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.

Hey girls, if the boys in your class are acting silly, you might as well leave them alone. You are far more sensible than them, aren’t you?

There is science to back up this theory. Scientists from Newcastle University, UK, and Seoul University, South Korea, found that the brain matures (成熟) earlier in girls than in boys. This is partly because of the way children’s brains are “pruned.”

As the brain matures, it begins to cut out unimportant information and focus on important information. This process is called “pruning.”

In order to learn more about this process, scientists scanned the brains of 121 people aged between 4 and 40. They found that pruning began much earlier in girls. Between the ages of 10 and 12, a girl’s brain will start to see a lot of activities as the pruning process starts. But for boys, this doesn’t start until the age of 15 to 20.

During this process, the brain will turn off memories, sounds or sights that appear several times. But important connections, like linking the sound of a familiar person’s voice to their face, are kept.

“The loss of connectivity during brain development can help to improve brain function,” scientist Sol Lim told the Daily Telegraph.

To understand this more easily, imagine you are at a party and everyone is talking. You can’t concentrate. But if you “turn off” some of the voices, it is easier to hear the others. The brain works in a similar way.

1.What did the scientists find?

A. Boys usually focus on unimportant information.

B. Girls never focus on unimportant information.

C. Girls mature earlier than boys.

D. Connectivity helps improve brain function.

2.What does the underlined word “pruned”probably mean?

A. 删减 B. 成长 C. 改变 D. 损失

3.What happens during the process “pruning”?

A. The brain doesn’t work for a moment.

B. You can’t remember, hear or see.

C. The connections between things disappear.

D. Brains develop to focus on important information.

4.What can we know from the passage?

A. Boys are more silly than girls.

B. Boys are less sensible than girls.

C. You can never concentrate at the parties.

D. Brains function better after losing some connections.
