The Most Attractive Trips for You

This afternoon, a friend asked if she could come by to spend some time with me in stillness.

Two days back, she got the news that her grandmother passed away» on the other side of the globe. They were very close, and due to some duties in the coming days, she couldn't leave right away to be by her side.

I am a priest. Although we are opposite sex and I actually don't know her well, there was a resonance (共鸣) in values that connected us. She had attended a few gatherings that some friends and I hosted, and her attendance had always added a gentle and friendly atmosphere to the circle, and in the talks she'd find herself in. I was touched by the way she asked for help — and her intention to spend time in silence and in a sacred space to honor and connect with her grandmother.

I was very busy that day, and I was already behind on a few deadlines. I had hoped to work late on to catch up. But it was so clear to stop and make time for this. This friend has such a modest personality, and I could tell it had been an uncertain couple of days since she received the news. "Of course, come by please," I told my friend.

When she arrived a couple of hours later, I handed her a cup of tea. It was 5:30 pm. She had wanted to sit in silence to honor her grandmother first, but because she had missed eating lunch, she gently brought a container of leftovers to share an early dinner instead.

I listened to her memories and stories. Her grandmother was the joyous community elder and had experienced the peaks and valleys in life with a lightness of heart.

After the meal, we sat together in stillness for an hour. When it was over, daylight had been absorbed by the night sky.

More than 100 scientists traveled to faraway places to collect wild crop seeds in an effort to help battle climate change. The scientists have been likened to the hero of the Indiana Jones movies. Like him, they had to face blood-sucking creatures and fierce tigers. Some-times, they had to use elephants for transportation because they couldn't find any other means of transportation.

A report on the project was published last week. It described the results of a six-year search to collect thousands of wild seeds. The seeds could be important in feeding a growing human population at a time when rising temperatures are affecting crop production in some areas.

The scientists traveled on foot, by four-wheeled vehicles, boat and riding horses and they even rode elephants to reach faraway areas. They collected 4,644 seed samples of 371 wild relatives of 28 crops. Many of those wild relatives are said to be endangered.

The Crop Trust, a nonprofit organization that works to save different kinds of crops, was directing the project. The group was working in partnership with Britain's Royal Botanic Gardens and Millennium Seed Bank. Additional financial support came from Norway. The project is believed to be the largest organized international effort yet to collect and protect crops' wild relatives.

Some relatives of widely grown crops have developed so they can survive usual and severe conditions such as low rainfall, flooding, extreme temperatures and poor soils. Scientists say the wild crops offer a largely unused source of diversity for protecting crops against climate change.

Some crops are threatened because of destruction of forests, conflict and expanded cities. Experts say losing this diversity could endanger food security around the world. A United Nations report says that food supplies are under severe threat. The report notes that the number of animal and plant species are quickly disappearing as the world deals with how to feed a rising population.

A new study suggests some of America's favorite Independence Day fireworks can give out lead and copper（铜）, which are used to give fireworks their vivid colors, and also damage human cells and animal lungs.

Led by researchers at NYU Grossman School of Medicine, the study showed poisonous levels of lead in two of 12 samples of commercially-available fireworks. Experiments using human tissue showed that lung exposure to particle emissions（颗粒排放物）from five types of fireworks significantly increased oxidation (氧化), a chemical process in the body that can damage or even kill cells.

The researchers say the new study, published online in the journal Particle and Fibre Toxicology, is believed to be the first to examine the effects of firework exposure in human cells and living animals, and to test for particles of common firework metals thrown into the atmosphere.

"While many are careful to protect themselves from injury from explosions, our results suggest that inhaling firework smoke may cause, longer-term physical damage, a risk that has been largely ignored," says study senior author Terry Gordon, PhD, a professor in the Department of Environmental Medicine.

Gordon and his team also analyzed 14 years' worth of air quality samples taken at dozens of sites across the US by the Environmental Protection Agency (EPA) throughout each year. They found that levels of poisonous metals were higher in samples taken on Independence Day and New Year's Eve celebrations than at any other time of the year. Along with lead, copper and other poisonous metals are commonly found in fireworks. "Our research shows that although we are only exposed to these poisonous substances for a short time each year, they are much more poisonous than the pollutants we breathe every day," says Gordon.

Gordon cautions that the current investigation is a first step, only addressing the potential effects of one-time exposure to the firework metals. He says repeated exposure is likely a larger concern. Nevertheless, he is planning to share his findings with local health officials, firework producers, the Environmental Protection Agent, and other regulatory agents to alert them to the potential for harm.

Many of the highest-scoring students owe their success to some surprisingly simple habits. It's not about brains，or about the amount of time spent studying..

♦Schedule your time. When a teacher assigns a long paper, you can draw up a timetable, dividing the project into small pieces so it isn't so challenging. It's like eating a steak.  Of course, even the best students delay sometimes. But when that happens, they face up to it. Sometimes it comes down to late nights. Still, if you want A's, you should make sure you hit the deadline.

♦Study anywhere or everywhere. When you learn English words, you can post a vocabulary list by the cupboard. Learn a new word every day while brushing your teeth. Study time was strictly a matter of personal preference.  Some wake up early to study. Still others study as soon as they come home from school when the work is fresh in their minds.

♦ If you want to study well, you should have your own learning system. Immediately file the day's papers in color-coded folders by subject so they'll be available for review at the exam time. Even you don't have a private study area, remain arranged in an orderly way. A backpack or drawer keeps essential supplies together and cuts down on time-wasting searches.

♦Learn how to read fast. You not only increase your words per minute but also learn to look at a book's table of contents, graphs and pictures first. Then, when you begin to read, you have a sense of the material, and retain a lot more.

A. Get organized.

B. Review properly.

C. You should chew it one bite at a time.

D. The best way to improve your reading efficiency is speed-reading.

E. Some straight-A students work late at night when the house is quiet.

F. You can read the whole book like swallowing the steak if you do try to.

G. Here's a handful of their secret ways that will help you become a straight-A student.

A few months ago, one of my fellow graduate students was offered an incredible career-building opportunity. His efforts on a student-led campaign to increase federal funding for basic research had 1 an invitation to speak on a conference panel（专家组）. It would look great on his CV（简历）. I was 2 for him, of course. I had been a（n）3 partner in the campaign. I felt that I deserved the same opportunity. Yet I hadn't been 4, and I wasn't sure why.

Growing up, I had been taught that the way to 5 was to put my head down and work hard. If my work was good enough, it would speak for itself and I would be 6. This, coupled with a natural 7, meant that I 8 worked up the nerve to put myself forward. However, I decided that I need to 9 my life again — by becoming my own big-gest 10.

So, with my 11 beating fast, I asked my colleague to ask the panel organizers to 12 me. My mind flooded with a list of well-practiced 13. Maybe I didn't deserve it. Maybe I was being too 14. But my colleague immediately contacted the organizers, who quickly agreed to 15 me to the panel. I've come to understand that I can't be recognized for my work if I'm invisible. This isn't a revolutionary 16, I know, but as an introvert (内向的人) this is my 17 Mount Qomolangma.

I think advocating for myself will always make me a little 18. But I do plenty of other uncomfortable things to 19 I'm living my best life, like getting flu shots. I suppose I can do the same for my 20.

Bike-to-Work Day is held every year across North America on the third Friday of May. It (start) by the League of American Bicyclists in 1956, which is aimed (promote) the bicycle as a serious choice of getting to and from work.

Another benefit of cyclic is that you may be more creative and full of energy once you get to work, which will improve your (perform).

Bicycles are a very common form of transport in the world. There (be) about one billion bicycles worldwide. That makes it the most popular invention ever. When we think of some (country), like China, we imagine a large number of people's cycling every-where. Even in high-tech Japan, is possible to see businessmen, farmers, mothers or workers in the streets on their bikes. We use bicycles today for recreation, fitness and so on.  the bicycle, much of the world might stop (work)!

My English was not good previous. But I have done whatever I could to improving my English in the past two years. First, I forced myself to memorize at least several new words every day. It is huge importance to learn English well. Seconds I went over the basic rules of grammars every week, which my English teacher expected me to master it. Third, I read short English articles and then wrote a English composition every others day. I neither want to get low marks in reading or hope to get low marks in writing. Now my English is improving day by day, and I hoped I am prepared for the come College Entrance Examination.
