    Albert Einstein is right once again! He thought of the idea about gravitational waves years ago with his Theory of Relativity, but scientists are finally discovering that it really exists now. But what are gravitational waves, and why are they important?

    Well, gravitational waves are made by black holes and can change time in space. Black holes aren't holes but are lots of matter put together into a very small area. They are created when a star, much like our sun, explodes and leaves behind this dense* material. It doesn't shine like a star any more, and it becomes black.

    The black holes that made these waves are special. About 1.3 billion years ago, there were two black holes that kept moving closer and closer together. Finally, they hit each other and formed one big black hole. The energy is given off and created the ripples* in space. These ripples are gravitational waves. For example, imagine you throw a stone into a pool. It creates ripples that change the shape of the water. Well, that's kind of what the influence of one black hole hitting the other has in space.

    Gravitational waves are hard to explore. But thanks to the efforts of scientists, the ripples were discovered on Feb. 11th, which is the first time in human history. Einstein was excellent to know this 100 years ago before we have the technology. It can give us a new view of the universe we live in. The discovery of gravitational waves, unlike stars, galaxies and other bright objects, black holes don't produce light, so we can't see them by tools. Gravitational waves allow scientists to look at the universe not only with light, but also with gravity. "Everything else in astronomy like the eye," A scientist told The New York Times. "Finally, astronomy grew ears. We had never ears before."

    Now, we will be able to find black holes and things that are much further away from Earth, which means much more space exploration in the future. And who knows, this discovery could even lead to time travel!

(1)、Gravitational waves are ripples that are created by
A、stars B、lots of matter C、different materials D、black holes
(2)、The third paragraph of the passage is mainly about     .
A、how black holes are formed B、how gravitational waves are created C、why gravitational waves are important D、why black holes are black
(3)、The discovery of gravitational waves can help people         .
A、understand the shape of water B、see black holes clearly C、learn more about the universe D、travel anywhere freely
(4)、What can we learn from the passage?
A、Albert Einstein discovered gravitational waves. B、Where there are black holes, there are gravitational waves. C、Gravitational waves are to astronomy what ears to people. D、Gravitational waves are easy for scientists to be found by light.

Do you feel lonely when your best friend isn't around? Here's our advice to you—and to all kinds who feel lonely sometimes. 

It's hard when a best friend isn't around—maybe because he or she moved to a different school or a different class. You may feelleft out during break(间歇)or lunchtime. You want to make new friends, but how do you find them? Maybe it seems like everybody else already has his or her own friends. But remember, there's always room for more friends. 

Start by looking around your classroom—think about which kids you'd like to play with during break. Look for chances(机会)to say hi to them, smile, and be friendly. Offer(主动提出)to share something or express(表达)your appreciation(欣赏)to them. Invite someone to play with you or say "Do you want to sit here?" in the lunchroom. When you're at break, walk over to kids you want to play with, act(举止)friendly, and say "Hi, may I join you?" or just join in. 

If you have trouble(问题)doing this or if you're feeling shy, ask your teacher to help you make new friends. Teachers are usually pretty good at matching(相配)people up. The best way to make friends is to be a friend. Being kind, being friendly, sharing, saying nice things, offering help—pretty soon, you'll have one, or two, or even more new friends. 

You might still miss that special best friend. But when you see each other again, you can share something you didn't have before he or she left: You can introduce him or her to your new friends!

 C. Read the passage and fill in the blanks with proper words. (在短文的空格内填入适当的词,使其内容通顺,每个空格限填一词,首字母已给):(7 分)

Since 2011, the Shanghai Peking Opera Company has held two seasons of "Youth Runway", a long-term opera development project hoping to find young opera talents (天才). 118 young performers have successfully showed 200 plays and classical (经典的) pieces. Most of them were born between 1995 and 2000, making them the company's newest p{#blank#}1{#/blank#}. They will show both classical and new plays in many different styles (风格).

"The Butterfly Lovers", one of the plays this spring, is changed from a s{#blank#}2{#/blank#} love story between a young poor man, Liang Shanbo, and Zhu Yingtai, the daughter of a rich family. They return as butterflies after their death (死亡). Another one, "Twelve Roles", which was shown in the summer, largely gets its i{#blank#}3{#/blank#} from an American film "12 Angry Men". Yueju opera, which developed around 1906 in Shengzhou, Zhejiang Province, is one of China's most famous operas. In the o{#blank#}4{#/blank#} days, people loved it because of its styles of singing and melodies (旋律) . Now, it is getting a new life. The performing season for young performers is held in its fifth year and has its own characteristic. Moreover, the project worked with BesTV to c{#blank#}5{#/blank#} a Yueju opera short video series (系列) about the 24 solar terms (节气) of the traditional Chinese calendar.

Every year, the China Shanghai International Arts Festival p{#blank#}6{#/blank#} chances for traditional opera performers like Yueju talents to perform. Many traditional opera performers have got fans among students and young performers in recent (最近的) years by showing how they prepare for a concert (演唱会) and behind-the- scenes stories with mobile apps on video websites.

They t{#blank#}7{#/blank#} many ways to make traditional art forms attractive (有吸引力的) to today's youth, including (包括) the creation of short opera films and the use of popular melodies. "We believe that Xiqu (traditional opera) like Yueju can attract today's young people because it can be mixed with different art forms," says Chen Daming, a theater critic.

March 14 is a great day for fans of maths. It is celebrated as Pi(π) Day, a day to celebrate the number that many people know very well. The date copies from the first three numbers of Pi(π). March is the third month and the 14th means one and four. Altogether it is 3.14. Pi(π) comes wherever there are circles(圆). Pi has been known for thousands of years and gets its name from a Greek letter, n. The Greeks are believed to be the earliest to use the letter in maths. The first Pi Day was celebrated on March 14,1988.

San Francisco's Exploratorium Science Museum started the event. The museum marks the day with a daylong celebration. March 14 is also the birthday of the famous scientist Albert Einstein. Princeton University, where Einstein lived for many years, celebrates Pi Day as well. March 14,2009, was celebrated as National Pi Day. And March 14,2019 also marked the one- year anniversary(周年纪念[1]) of the death of Stephen Hawking. And how do people celebrate the Pi(π) Day? Maybe you can try these ideas:

Eat or make different kinds of pies(for example, apple pies, cherry pies, and even pizza pies);

Celebrate the day with a pie cut using the mathematical constant(常数) of Pi(π);

Discuss the importance of the letter π;

Watch Life of Pi in cinemas;

Look for the number 3.14 in every place(such as prices and street numbers).
