All languages change over time, but some change at a faster rate than others. The most important factors are the number of people who speak a language, where they live and whether they move around, the importance of the language for world trade and communication, and changes in technology.
However, today English is the most widely used language in the world. English is spoken by about 350 million people as a first language in countries such as Great Britain, the United States. In addition, about a billion more people speak English as a second language.
English started to take over French as an international language during the period of British colonialism (殖民主义) when the English ruled many countries in Africa and Asia. The colonial period came to an end at the same time that several other changes occurred. For example, the U.S. started to play a greater part in global affairs and the international economy. New means of communication technology such as television and the Internet spread English worldwide. In addition, they could use the Internet for information, business, or e-mail communication, all in English. Just as the use of English spread, other languages changed English by contact or by new inventions and technology.
In contrast, Icelandic is a language that has changed very slowly. Icelandic speakers today can understand poetry written in a slightly different dialect over 1,000 years ago! Why has Icelandic changed so slowly? The main reason is the isolated (孤立的) location of the island in the middle of the Atlantic Ocean. Compared to England, Iceland had no history of colonialism. Iceland's small population has not played a major role in international trade or communication. Today, most Icelanders speak English in addition to their native language. With outside influences, Icelandic is changing more rapidly now.
A. People everywhere could watch the news or sports events in English.
B. These changes have a great influence on the development of society.
C. Isolation meant that for hundreds of years, Icelanders had little contact with speakers of other languages.
D. What are some of the factors that influence how quickly a language changes?
E. The language communication brings about the communication of technology.
F. In the past, other languages such as Latin or French were more important than English.
G. English was the primary means of communication in these colonies.

If you travel, you will leave a carbon footprint in your wake. You can't help it. But eco-friendly travel practices can lighten the harm on Mother Earth. Green travel is not a passing trend but a lifestyle choice. .
Choosing a green destination
No destination is a Green Giant. . However, some countries and cities show a deep commitment to Earth-friendly policies and practices. When researching a vacation spot, look for places that naturally embrace the green lifestyle.
Choosing green transportation
What makes Mother Earth proud? Seeing you use your own power to get around. Many adventure tour operators arrange cycling, hiking and walking holidays. . The greenest rides typically run on electric power. Switzerland is taking the lead with its hybrid buses and trains powered by hydroelectricity; Japan is running close behind.
Choosing a green hotel
Once you are at your destination, if you can get the hotel right, you can make the greatest impact. . Look for a fact sheet online, or call the front desk. You can also search for hotels approved by respected certification programs, such as Green Key and the Global Sustainable Tourism Council.
.
The Earth-friendly choices are numerous: You can sail, bike, kayak, bike, swim, bird-watch and play I-spy-a-monkey in a tree. Visit a local food market, and don't forget to bring a reusable bag for purchases. You can also lend a hand during your holiday. The green movement has changed from how to preserve and protect to how to use less and do good when you're there.
A. Choosing green travel
B. Choosing green activities
C. Next in line are trains and buses
D. They all make environmental missteps
E. Most major chains operate in-house green program
F. If you plan to drive, consider a fuel-efficient vehicle

|
A. Height played a major factor. B. No such association was seen for men. C. The study was observational and couldn't establish cause. D. In fact, the study found that the optimal level of activity for women was 60 minutes a day. E. Neither height nor weight seemed to factor into whether the men reached their 90s, but activity level did. F. In addition, for each 30 minutes a day the men were active, they were 5％more likely to reach that age. G. And they included dog walking, gardening, home improvements, walking or biking to work and sports. |
Living to the ripe old age of 90 may depend on your body size—both height and weight—as well as your level of physical activity, and geeing to influence a woman's lifespan more than it does a man's.
The study found women who lived to 90 were, on average, taller and had put on less weight since the age of 20 as compared to women who were shorter and heavier. However, men saw more benefit from physical activity than women.
In 1986 researchers asked over 7, 000 Norwegian men and women between age 55 and 69 about their height, current weight, and weight at age 20. Both genders also told researchers about their current physical activities. The men and women were then sorted into daily activity quotas: less than 30 minutes, 30 to 60 minutes, and 90 minutes or more.
Men and women in the study fared very differently when it came to the impact of body size and exercise.
Women who weighed less at age 20 and put on less weight as they aged were more likely to live longer than heavier women. The study found women who were taller than 5 feet 9 inches were 31％more likely to live into their 90s than women who were less than 5 feet 3 inches.
Men who spent 90 minutes a day or more being active were 39％more likely to live to 90 than men who were physically active for less than 30 minutes.
However, women who were physically active for more than 60 minutes a day were only 21％more likely to live to 90 than those who did 30 minutes or less. And unlike men, there was no bonus for increasing activity.
How to Cultivate Confidence?
When faced with a big challenge where potential failure seems to appear at every corner maybe you'll hear this advice: "Be more confident." Take the belief that you are valuable, worthwhile, and capable, also known as self-esteem. Confidence turns thoughts into action. It comes from the genes you are born with, the way people get used to treating you as well as the choices you make. While it isn't possible to completely separate these three factors, the personal choices we make obviously play a major role in confidence development. As a result, by keeping in mind certain practical tips, we do actually have the power to cultivate our own confidence.
If you're looking for a long-term change, consider the way you think about your abilities and talents. Do you think they are fixed at birth, or that they can be developed? These beliefs mater because they can influence how you act in the face of setbacks, if you have a fixed mindset, meaning that your talents are locked in pace, you might give up, assuming you've discovered something you're not good at. But if you have a growth mindset, and think your abilities can improve, a challenge will become an opportunity to learn and grow. Neuroscience(神经学)supports the Jatter. The connections in your brain do get stronger and grow with study and practice.
Practicing failure is a must. Failure happens. J.K. Rowling was rejected by twelve different publishers before one picked up Harry Potter. The Wright Brothers built on history's failed attempts at flight before designing a successful airplane. Studies show that those who fail regularly and keep trying anyway are better equipped to respond to challenges in a constructive way. So, think of a challenge you want to take on, realize it's not going to be easy, accept that you'll make mistakes, and be kind to yourself when you do. You'll feel the excitement, knowing that whatever the result, you'll have gained greater knowledge and understanding.
A. But what is confidence?
B. So can confidence be easily cultivated?
C. Everyone is possible to encounter failure.
D. Being a talented person is quite necessary.
E. They learn to try different strategies and persevere.
F. Believing in your abilities to improve is the first step.
G. It also turns out that people with a growth mindset are better at dealing with challenges.
Is our planet heating up? Are human beings to blame for climate change? The discussion on this subject has been heated, but what are scientists actually saying? At Reader's Digest, we decided to find it out.
Yes, it has, and even warmer. Greenland was forested between 450,000 and 800,000 years ago, so temperatures were considerably warmer then. There have also been other times of relatively high temperatures.
So why does the concern exist?
It's all about the speed at which temperatures are changing. But in the 20th and 21st centuries, especially since 1976, temperatures have probably risen more quickly than during any century in the past 1 ,000 years. Warming may bring improved crop production and other benefits to northern countries such as Canada or Russia. However, many species may not adapt to these conditions, and the one that is able to may cause a problem. The West Nile virus, first seen in North America nine years ago, infected about 4,000 people in the US in 2006. The mountain pine beetle, which is active during warmer winters, has already destroyed about 13 million hectares of Canada's forests, worth an estimated $6. 4 billion.
What is causing the warming?
IPCC has concluded that human activity is very likely responsible, by increasing the concentrations of greenhouse gases and thus the greenhouse effect. They argue the human contribution is nothing.
A. Some scientists, however, still disagree.
B. Has the planet ever been this warm before?
C. Has human behavior made the planet warm?
D. Temperatures have been changing all the time.
E. In the past, temperatures moved up or down gradually.
F. Mosquitoes have been moving northwards to higher places.
G. These questions have burst into newspapers, films and popular books.
My first career had been related to audiology (听力学)—one that allowed me to work part time while tending my growing family. But when my children grew up and left home, I found myself longing to be outside, not in a soundproof room in the hospital.
So I began attending classes at the local university, hoping that might lead me to a new career. "What gave you pleasure as a child?" the counselor (顾问) asked. I thought for a while before responding, "Playing outside in the woods." Our discussion eventually led to a second master's degree, this one in zoology, and the job as a naturalist at a state park. I was 44 years old.
But as I climbed the career ladder, my time in the field disappeared. I was chained to a computer screen. In the back of my mind, the career counselor's question sounded again. ""
Shortly thereafter, an opportunity presented itself: a 4-month field research project at a university in the Netherlands. I found that field research allowed me to play in the woods again, but with a new purpose.
At the end of the project, I was invited to participate in the "sandwich" Ph.D. program, in which students do research in their home country while receiving support and instruction in the Netherlands. I was 60 years old. I didn't think that earning a Ph. D. would further my career.
Still, my colleagues raised their eyebrows. "" they asked, "It is all about the journey," I responded.
A. What gave you pleasure as a child?
B. I also went to see a career counselor.
C. What do you intend to do with a Ph.D.?
D. But I wanted to follow my new passion.
E. But when it was no longer right, I changed direction.
F. Can you believe you're actually getting paid to have this much fun?
G. And I was delighted to once again experience the joy of being outdoors.

A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that woman next door has a green thumb if her garden continues to grow long after your plants have died.
The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.
The green－eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play Othello.

How to Be Eco-friendly
If you'd love to be more eco-friendly but don't know where to begin, start with a few small changes.
Lowering Your Energy.
Turn off lights and unplug power strips (电源插板) that you're not using. Since some devices can still use energy even when they're turned off, turn off these power strips at night to completely cut off energy use. If you need to leave your computer, or TV on, try setting it to sleep mode instead of simply leaving it on.
Using public transportation.
Keeping cars off the road in rush hours can also improve the air quality. If you do need to drive somewhere, ask friends if they'd like to carpool (拼车) , so fewer cars are on the road.
Say no to unnecessary plastic straws, lids, and bags and stop using plastic wrap and plastic containers for food storage. Instead, you can use reusable water bottles made of sustainable material like glass, bamboo, and ceramic.
Considering growing a plant.
They add more oxygen to the air, which means a less polluted air. If you don't have a green thumb, choose some plants that are rather easy to look after. If possible, grow more than one plant.
A. Reduce your gas consumption and carbon emissions by walking, biking, or taking the bus.
B. Here are some suggestions for you to live an eco-friendly life.
C. Use less energy during the hot summer months and cold winter season.
D. This is an easy way to reduce energy use.
E. Using items more than once.

Natural disasters come without warning, and this underlines the need for disaster management. Natural disasters may cause death or damage crops and properties without warning. Emergency management can reduce the damage and save more lives than if there are no systems set up for disaster security (安全).
There are steps to take when you plan for a natural disaster. Here's a list of some of them:
⒈Ask your local Red Cross chapter or emergency management office for reminders of disasters and emergency management steps. You may also request a list of emergency steps that should be done in each type of disaster.
⒉Each community has its own set of emergency signals. Knowing what to do at once gives you a head start in any emergency.
⒊Include discussions on what is likely to happen and what should be done in such cases. Plan how each one of you will react and what are the responsibilities of each one, in order to be able to work as a team.
⒋Set a meeting place in case of a natural disaster. It should be one within the vicinity (附近) of your workplace or home, and one outside your immediate vicinity. Agree on an emergency telephone that everyone should try to call.
⒌Prepare a disaster supply toolbox. Stock it with first aid supplies. Prepare emergency lights like flashlights with batteries. Include a battery-powered radio in the kit so you can listen to updates.
A. Find out what they sound like and what they mean.
B. Discuss the dangers of different types of natural disasters.
C. Try to understand why these signals sound unfamiliar to you.
D. Everyone should try to reach it when a natural disaster happens.
E. Prepare some water and food that should be enough for three days.
F. Find out any disaster management plan that your community has.
G. This is also the best time to ask what kind of disasters may likely take place.

Do you think studying in a different country is something that sounds very exciting? Certainly, it is a new experience, which brings the opportunity of discovering fascinating things and a feeling of freedom. You will experience culture shock. Evidently, at least four essential stages of culture-shock adjustment occur.
The first stage is called "the honeymoon". In this stage, you feel excitement about living in a different place, and everything seems to be marvelous.
Eventually, however, the second stage of culture shock appears. This is the "hostility stage". You become tired of many things about the new culture. Moreover, people don't treat you like a guest anymore. Everything that seemed to be so wonderful at first is now awful, and everything makes you feel distressed and tired.
Then you come to the third stage called "recovery". You start feeling more positive, and you try to develop comprehension of everything you don't understand. The whole situation starts to become more favorable.
The last stage of culture shock is called "adjustment". The things that initially made you feel uncomfortable or strange are now things that you understand. Now you feel comfortable; you have adjusted to the new culture.
A. Actually, culture shock is something you cannot avoid when studying in a foreign country.
B. You have reached a point where you feel good because you have learned enough to understand the new culture.

Set time. You should have some time during every day when you'll read for at least 5 to 10 minutes. For example, make it a habit to read during breakfast and lunch and even dinner if you eat alone.
Always carry a book.When I leave the house, I always make sure to have my car keys and one book at hand. The book stays with me in the car, and I take it into the office and to appointments and pretty much everywhere I go.
Find a place in your home where you can sit in a comfortable chair. Don't lie down unless you're going to sleep. There shouldn't be a television or a computer near the chair, and no music or no noisy family members/ roommates. If you don't have a place like this, create one.
Reduce television/ the Internet. If you really want to read more, try cutting back on time on TV or the Internet. Still, every minute you reduce of the Internet/ TV, you could use for reading. This could create hours of book reading time.
A. Wherever you go, take a book with you.
B. Go to bookstores.
C. Have some good tea or coffee while you read.
D. Find a quiet place.

Healthy eating is not just what you eat, but how you eat. Here are some tips for you:
Eat with others whenever possible. Eating with other people has numerous benefits, especially for children. Eating in front of the TV or computer often leads to mindless overeating.
Take time to chew(咀爵) your food and enjoy mealtime. We tend to rush through our meals, forgetting to enjoy the flavor and feel the taste of what is in our mouths.
Ask yourself if you are really hungry, or have a glass of water to see if you are thirsty instead of hungry. During the meal, stop eating before you feel full. It actually takes a few minutes for your brain to tell your body that it has had enough food, so eat slowly.
A healthy breakfast can jumpstart your metabolism(新陈代谢), and eating small, healthy meals throughout the day (rather than the standard three large meals) keeps your energy up and your metabolism going.
Avoid eating at night. And then don't eat for 12-14 hours until breakfast the next morning. Studies suggest that eating only when you're most active and giving your digestive(消化的) system a long break each day may help to keep fit.
A. Drink plenty of water.
B. Try to have dinner earlier.
C. Be careful when eating out.
D. Eat your food slowly, tasting every bite.
E. Listen to your body.
F. It allows you to follow others' healthy eating habits.
G. Eat breakfast, and eat smaller meals throughout the day.
Do you want to be at the top of your class? Add these tips to your life and you should be on your way to being a top student!
I cannot stress (强调) enough how important it is to pay attention to what your teacher is teaching you. Take part in class discussions if you have something worthwhile to add. Pay attention during class, especially during lectures.
Taking notes is important. You don't need to write down every word your teacher says but write down what he writes on the board, or any special fact you think you might need for a test.This way it will help you learn more effectively by actually thinking about what you are writing.
Don't skip school (逃学).You will be missing out on stuff. However, you will have more work because you have missed lectures. Also, try not to be late for class. It's most likely that your teacher won't appreciate it and you will get yourself behind.
If you have an "I don't care about school or this class" attitude, then teachers will be less willing to offer you extra credit (学分).The same goes for lazy attitude. Have a respectful attitude to the teacher and other students. Try not to laugh when other students make a mistake.
Always ask questions.If you don't understand, ask someone. Read your textbook and notes, and then if that fails, seek help. Ask a teacher, friend, classmate, parent, etc. Get a tutor if you need one.
A. Be prepared.
B. Write in your own words.
C. Staying organised will be helpful.
D. Keep a good attitude toward things.
E. There is no shame in needing some help.

Have you ever tried skiing? Skis are long, mostly flat pieces of metal, wood, or plastic. Skiers attach them to their shoes and use them to get over snow, often down a mountain slope. Nordic skiing and Alpine skiing are major events of the Winter Olympic.
Nordic skiing started in Norway and other countries of north Europe. Cross-country skiing takes place on open, hilly land. A cross-country skier must be able to ski uphill, downhill, and cross flat areas. As for a ski-jumping competition, the skier gets down a steep ramp (斜坡) that curves upward at the end. The skier leaps off the end and tries to "fly" as far as possible and then lands on his or her feet.
Alpine events include downhill and slalom racing. Downhill racing is the fastest and most dangerous of all skiing events. The skiers go down a long, steep course that may have large bumps (隆起物). Along the course are gates formed by single poles or pairs of poles. The skier must ski between them and stay on the course. The winner is the skier who completes the course in the shortest time. Slalom racing is similar to downhill racing. However, a slalom course is shorter and more winding (蜿蜒的) than a downhill course.
A. It requires the skier to make high-speed turns.
B. Alpine skiing started in the Alps of central Europe.
C. Skiing is a winter sport that involves the use of skis.
D. The skier who leaps the farthest and has the best style is the winner.
E. Nordic skiing events include cross-country racing and ski jumping.
F. The skier races over and around large bumps of snow called moguls.
G. They are allowed to touch gates with their bodies as long as their skis stay on the course.
Maybe in the near future, driverless cars may become common on the roads. Driverless cars have already been test-driven thousands of miles. For instance, it helps reduce the number of accidents and traffic jams.
That is because there are many issues that must be solved before the widespread use of them. One problem is that a driverless car cannot predict problems far down the road like a driver can. The driverless cars react to an emergency only when it actually occurs. For instance, a driver starts to slow down when he sees a child riding her skateboard directly into the road 0.2 km away.
Driverless cars are not suitable for extreme weather conditions. They don't predict or "feel" that the roads have become icy like an experienced driver would. For instance, when a road is icy, a human driver would step on the brakes more gently than when the roads are clean and dry.
Another issue is that driverless cars have maps programmed into their memory, but these maps aren't always updated and accurate. New roads are built, and old roads are closed down. Perhaps one day, driverless cars will be everywhere, but we are not ready for that just yet.
A. The safety problems have almost been addressed.
B. However, they are not yet available for the public.
C. Many advantages can be associated to the driverless cars.
D. Driverless vehicles also have trouble adjusting to new roads.
E. They may become confused by fog, heavy rain, or heavy snow.
F. Due to this, a driverless car may get passenger to the wrong destination.
G. But the driverless car only takes action when the child is in its immediate path.
How to Have Fun During a Long Car Ride
Are you afraid of that long, family car ride? Boredom can be avoided. The following are some things that you can do so that you won't feel bored any more.
Read a book. If you do feel carsick, stop reading. Get a book that is full of action — this should keep your mind busy and make you feel time flies.
