You might have learned in your science classes that the sun is quite large and heavy. What if you heard that we’ve found a black hole that contains the mass (质量) of nearly 70 suns?

Chinese scientists used LAMOST, a powerful Chinese telescope (望远镜), as well as telescopes in Hawaii and the Canary Islands, to make this discovery.

According to Einstein’s theory, black holes come from dying stars. The star collapses (坍塌) into a small point with a lot of mass and strong gravity (引力). The strong gravity of the black hole allows it to pull other things in and “eat” them. Scientists search for black holes by looking at x-rays that are released when they “eat” nearby stars. However, when black holes are inactive, this method doesn’t work.

This time, the researchers looked at stars that orbit invisible (看不见的) objects. These objects, they believe, cannot be anything but black holes. After calculating (计算) the speed of one particular star in a star system named LB-1, the scientists figured out that it was orbiting (绕轨道运行) a stellar-mass black hole.

The black hole’s mass is about 70 times the mass of our sun. According to current theory, this black hole shouldn’t even be able to exist. It was previously believed that the mass of such a black hole cannot be bigger than that of 25 suns. Stellar (星球的) winds blow away the heavy elements that are left behind when a star dies. But somehow, this black hole kept most of its heavy elements.

Researchers said it is possible that the black hole formed out of two large stars that died and merged (结合) together.

The discovery is also inspiring some researchers to revisit their previous studies. “This discovery forces us to re-examine our models of how stellar-mass black holes form,” University of Florida physicist David Reitze was quoted as saying in a press release.

1.How did Chinese scientists find the stellar-mass black hole?

A.By looking at stars moving away from the black hole.

B.By studying x-rays that came from the black hole.

C.By calculating the gravity of a nearby black hole.

D.By looking at the speed of a star that orbits it.

2.What does the underlined word “inactive” mean in Chinese?

A.积极的 B.不活跃的 C.快速的 D.活泼的

3.What do we know about the black hole?

A.It is much heavier than the sun. B.It is moving faster than the sun.

C.It hasn’t “eaten” any stars. D.It will disappear soon.

4.What is the last paragraph about?

A.The importance of this discovery.

B.Previous studies on black holes.

C.The formation (形成､构成) of stellar-mass black holes.

D.The preparations that were done before making this discovery.

5.What do we know from the story?

A.Black holes are usually heavier than 25 suns.

B.We cannot believe current scientific theories.

C.Black holes can form after stars die.

D.Stellar-mass black holes contain no heavy elements.

Good morning, class!

We know that there are too many net bars around us. The Internet is popular and it makes our lives colorful. Many of us like going online very much because we can learn how to use the computer and get more information from the Internet. We can learn English. We can read some good newspapers and magazines. It can make us clever in playing computer games. We can send E-mails to our friends quickly. We can chat(聊天) freely online with our friends. It can help us get in touch with people from all over the world.

But some students spend too much time in playing computer game and some stay in the net bars all day and all night. Teenagers even get to have boyfriends or girlfriends online. They write too many letters to each other. It takes them to much time to chat online so they do worse and worse in their lessons and they don’t study well any more. I think we mustn’t get online when it is time for us to study. We can do it in summer or winter holidays. We should get online with adults(成人)--our teacher or parents.

At the same time, if we have lots of free time, we can do some out-of-class activities at school. We usually have activities from 4:50 to 5:50 in the afternoon. We have different kinds of activities. If you are interested in sports, you can play basketball or football. We can go to the English Corner. We can practice talking in English there. We hope we can spend more time on our subjects or on such activities that we can learn a lot from and less time on the Internet.

Thank you for listening to me. That’s all.
