Are you looking for some new and exciting places to take your kids to? Try some of these places:

●Visit art museums. They offer some activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling

●Head to a natural history museum. This is where kids can discover the past from dinosaur models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.

●Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet (木偶) making and stage make-up are just a couple of the special offerings you might find.

●Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.

Being compared to great people like Stephen Hawking and Albert Einstein is not something that happens to the average person. At the age of just 23, Sabrina Gonzalez Pasterski has already achieved much more goals than most of us ever will in our lifetime.

When she was only 14 years old, the Chicago girl made her own single engine airplane—by herself. She then flew it across Lake Michigan, becoming the youngest person to ever fly their own plane.

She graduated from Illinois Mathematics and Science Academy (IMSA) in 2010 and entered Massachusetts Institute of Technology (MIT).

At first, she had to wait to be accepted into the school, but once Professors Allen Haggerty and Earll Murman watched her video they had no doubt. Femalista quoted Haggerty as saying: After just three years at MIT she has already achieved the highest possible grade point average of 5.0.

She is now studying further at Harvard University, with full academic freedom. Once again she is only 23 years old.

What's even more impressive is that she is no longer interested in building planes but has turned her attention to physics, namely black holes and how gravity (重力)affects space and time—that is why she is being compared to Einstein and Hawking.

Pasterski records all of her work on her website Physics Girl, but if you are a little shocked by her achievements, she has some words for you.

During an interview with Marie Claire earlier this year she said, "Being optimistic about what you believe you can do. When you're little, you say a lot of things about what you'll do or be when you're older—I think it's important not to forget those dreams."

Most people shake hands and make eye contact when they meet people for the first time. Among very good friends, a woman may give another woman a little hug, and a man may kiss a woman quickly on the cheek. Males don't hug one another, which, however, is changing. Men usually shake hands with the right hand. Sometimes they use the left hand to either cover the handshake or lightly hold the other person's arm. This shows greater warmth and friendship. Most people wave hello or good-bye by extending the palm(手掌) facing outward, and twisting the hand at the wrist. Another way is to raise the arm, palm outward, and move the whole arm and hand back and forth. This is important to know because in many other countries, the same movements mean "no".

When people are waiting in a public place, such as the post office, they usually form lines. Some people get angry and complain if someone pushes their way into a line or jumps ahead of other people. Moreover, many women like men to open doors for them. They also like men to give up their seats on public transportation. However, some women do not like this type of behavior. They feel that men and women should be treated in the same way.

In the United States, it's important to make direct eye contact in business and social situations. If you don't make eye contact, people will probably think that you are bored or not interested. If there is silence in these situations, people usually try to make conversation. Periods of silence make many people uncomfortable. People in the United States usually stand about one arm's length away from each other while talking or standing together. This space is called "the comfort zone".

In the United States, mothers sometimes show that they are angry with children by shaking an index finger(食指) at them. People may show that they like children by patting them on the head.

World Health Organization (WHO) chief scientist Soumya Swaminathan said Monday that herd immunity to coronavirus would not be achieved in 2021, despite the growing availability of vaccines (疫苗产量).

Factors that delay herd immunity include limited access to vaccines in developing countries, skepticism (怀疑) over vaccination, and the potential for virus mutations (变异), according to health experts.

A growing number of countries around the world, including the United States, the United Kingdom, Singapore, Germany and other European Union countries, are in the first stages of mass-vaccination campaigns.

Herd immunity occurs when enough people in a population have immunity to an infection(传染) so that it prevents the disease from spreading.

"We are not going to achieve any levels of population immunity or herd immunity in 2021," Swaminathan said, while emphasizing that measures like physical distancing, hand washing and mask wearing continue to be necessary in controlling COVID's spread for the rest of the year.

However, Swaminathan praised the "incredible progress" made by vaccine researchers to develop several safe and effective vaccines at unprecedented (空前的) speed. Countries are currently administering vaccines developed by BioNTech-Pfizer, Oxford University AstraZeneca and Moderna.

"The vaccines are going to come," she said. "They are going to go to all countries, but meanwhile we mustn't forget that there are measures that work," she added, referring to hygiene (卫生) and social distancing.

"We won't get back to normal quickly," Dale Fisher, chairman of the WHO's Outbreak Alert and Response Network, told a conference hosted by Reuters news agency. "We know we need to get to herd immunity and we need that in a majority of countries, but we are not going to see that in 2021," Fisher said. "There might be some countries that might achieve it but even then that will not create normal especially in terms of border controls," he added.

2050 seems a long way away, but it is not impossible to predict the future. With the speed we are moving now so many amazing things are going to happen in the future.

 Let's start our predictions.

·The Internet will be free for everyone.

The Internet is really a key driver these days.  There have already been attempts like Facebook's Free Basics. Though it hasn't happened yet, there is a very strong possibility that the Internet will be free for everyone in the future.

·

With the increasing population, it is not very hard to predict that common methods of transportation will not be enough. There will be much heavier traffic on the road. So in this case personal airplanes will be a handy method of transportation for common people.

Of course, there will be proper air traffic control for these personal airplanes.

·Most cancers will be treated successfully.

 It will be a huge achievement in the history of medical science. Many studies are already showing a trend (趋势) towards this.

·Humans will live on other planets.

There will be great achievements in space research.  

We will receive more intelligent signals from space. Chances are we will be able to find the next Earth-like planet.

A. But it is not free for everyone yet.

B. So where is technology going in the future?

C. The world's population will cross 9.6 billion.

D. What do you think of my predictions of 2050?

E. In the year 2050, humans will be able to live on Mars.

F. Personal airplanes will be used widely for short journeys.

G. The number of deaths caused by cancers will be greatly reduced.

I remember my first day to go to a new school in the 2nd grade. My dad accompanied me to the bus stop. As we waited for the bus, I just held his hand 1, but it still couldn't remove my clear sense of fear and anxiety. The moment finally arrived at which I had to2this new environment at a school where I had no friends, no 3teachers or classmates. It seemed everything would be full of 4.

The school bus pulled up. I turned around and 5to my father. As I boarded the bus, my 6continued to grow and I turned around once again to make a farewell gesture to my dad. When the bus pulled away, I couldn't help 7.

Being lonely, I was very 8in the classroom. I glanced out of the window and I really expected to see his kind figure. To my 9, there he was! He stood there, making the shape of a heart to 10me and mouthing to me, "Everything will be okay." It was 11to me that my father had seen me crying so he 12the school bus. He wanted to make sure that I would get and stay there 13and that my first day wouldn't worry him.

With his 14, I'm now studying in Princeton University. Today is Father's Day, and I want to say that love is not about changing each other but 15each other.

There are several reasons why school uniforms are a good idea. First of all, uniforms help the school look smart. The students feel that they belong to a particular group. When every pupil in the school wears the uniform, nobody （have）to worry about fashion. Everybody wears

 same style of clothes. Uniforms can be useful in unexpected ways. A school in Ireland has introduced an interesting new uniform. On the edge of the jacket, there is a piece of cloth  gives off light in the dark. When the children are walking or  (cycle) to school on dark mornings, car drivers can (easy) see them.

But can uniforms help improve school standards? The answer this question is not clear. One study in America found that students' grades (improve) a little after the school introduced uniforms. But some students didn't want (wear) the uniform. Other American studies showed no (connect) between uniforms and school performance.

School uniforms are (tradition) in Britain, but some schools are starting to get rid of them. Some very good schools don't have a uniform policy. However, uniforms are still popular. Pupils at about 90 percent of British secondary schools wear uniforms.
