    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.

World Book Day is on April 23rd every year. It was set up by the UNESCO(联合国教科文组织)in 1995 to encourage people, especially teenagers, to find out the fun of reading. It is also the day to honor great writers, for example, William Shakespeare, born or dead on that day.

Many countries celebrate World Book Day. Take the UK as an example. On that day, millions of schoolchildren can buy books at a much lower price than usual in any bookstore. It has been done every year since 1998.

World Book Day is also celebrated in China. Xi Jinping, Chinese President, does lots of reading every day though he is very busy. On World Book Day 2020, he called on young people to do more reading. "Books cannot change the world, but people can change the world by changing themselves through reading." he said.

Reading can be good for people in many ways. Reading gives us information about other cultures and places of the world. When we read, we may find many things that we don't know. We would have to use our head to think about them or do more reading to find out the answers. The more we read, the more we know. The more we know, the smarter we become. What's more, reading is also one of the most important ways to learn a foreign language like English. We all know that it is difficult to learn everything in the classroom, such as the ways English people are speaking and writing today. Reading helps us.

"Reading makes a full man." Bacon said. Therefore, it is necessary for us to spend time on reading every day.

 阅读以下短文, 从每小题的A、B、C、D四个选项中选出最佳选项。

Taking public transportation(公共交通) in the United States, you can often see people reading books on their way to school or work. But in China, I rarely (很少的) see people reading during their free time. 

Are people's attitudes toward reading different here?Not really, Data (数据) released by Amazon China in December 2017 show that Chinese people still read a lot. They simply prefer e﹣books over regular books. 

However, other data show that reading is still more popular in the US than in China. Is there a reason for this difference?I'm not sure. What I do know is that China has a rich history of literature (文学) (From classic novels like Romance of the Three Kingdoms(《三国演义》) to the modern science﹣fiction books The Three﹣ Body Problem(《三体》), Chinese writers have created many fantastic written works. Perhaps the difference starts from childhood. Reading textbooks and doing homework can make you feel quite tired. By the time you finish it, you might not fell like reading for fun. Chinese students definitely (肯定) have to read more and do more homework than US students. So it's no wonder that they might not want to read much in their spare time. 

But learning to love reading can be great. Reading can open doors to places, people and ideas that you cannot imagine. Even just a single book has the power to change your own beliefs and attitudes. Where will your next book take you?
