The idea for a science experiment can come from an unusual place. After watching a YouTube video of a dancing bird named Snowball, a scientist in Californina decided to study the ability of animals to keep the beat.

Bird lovers have long claimed that their pets have rhyhm, and there are many videos of dancing birds online. Until now, scientists have suspected that humans are the only animals that can accurately keep rhythm with music.

Thanks to Snowball, that scientific opinion is changing. Snowball is a cockatoo, a kind of parrot, and his favorite song is “Everybody” by the Backstreet Boys. When he hears the song, he moves his feet and rocks his body with the tempo, or pace of the music, as though he is the only bird member of the boy band.

Aniruddh Patel is a neuroscientist, or a scientist who studies how the brain and the nervous system contribute to learning, seeing and other mental abilities. He works at the Neurosciences Instiute in San Diego. After seeing Snowbaill’s dance online, Patel visited the cockatoo at the bird rescue facility he’s called home for two years. The scientist played “Everybody” for Snowball and also played versions of the song that were sped up or slowed down. Sometimes, Snowball danced too fast or too slowly. Often, when there was a change in tempo, Snowball adjusted his dancing to match the rhythm. In other experiments, scientists have observed the same abilities in preschool children.

Patel isn’t the only scientist who has studied Snowball’s moves. Adena Schachner, who studies psychology at Harvard University, also wanted to know more about the dancing bird. Schachner’s team played different musical pieces for Snowball and a parrot named Alex, as well as eight human volunteers. The scientists observed that the birds and the humans kept time to the music with about the same accuracy.

Schachner and her team watched thousands of YouTube videos of different animals moving to music. Not all the animals could dance, however. From watching the videos, the scientists observed that only animals that imitate sounds, including 14 parrot species and Asian elephants, accurately moved in time to music.

The underlined words “that scientific opinion” in the third paragraph refers to the theory that .

A.birds like Snowball have the ability to keep the beat

B.humans are the only animals that can accurately keep rhythm with music

C.the brain and the nervous system contribute to some mental abilities

D.bird pets can have their special rhythm under human’s instruction

From the fourth paragraph we may know that .

A.Patel is the only scientist who has studied Snowball’s moves.

B.Snowball is able to adjust his dandcing to match the rhythm.

C.Snowball cannot dance to the versions of the song Everybody.

D.it is the brain and the nervous system that control the mental abilities.

The idea of studying animals’ ability to keep the beat comes from .

A.bird lovers’ discovery B.humans musical sense

C.the same abilities in children D.videos of dancing birds

According to the scientists, Snowball’s ability to dance to music is probably related to the fact that .

A.it is the only bird member of thd Backstreet Boys band

B.it has the ability to imitate sounds

C.it is a kind of dancing parrot

D.it has the same abilities as preschool children

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.

So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.

Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.

Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we' re very sad until we cry. We learn about our emotions through crying, and then we can deal with them.

Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural — and healthy — emotional response.

1. People can do benefit from crying except_______?

A. reduce pressure

B. attract help from other people

C. learn about our emotions through crying

D. cause healthy problems

2. Why didn't the author cry when her grandmother died?

A. Because her father did not want her to feel too sad.

B. Because she did not love her grandmother.

C. Because she was too shy to cry at that time.

D. The author doesn’t give the reason.

3. It can be inferred from the text that ______.

A. there are two ways to keep healthy

B. crying does more good to health than laughing

C. crying and laughing play the same roles

D. emotional health has a close relationship to physical health

4. According to the author, which of the following statements is true?

A. Crying is the best way to get help from others.

B. Fighting back tears may cause some health problems.

C. We will never know our deep feelings unless we cry.

D. We must cry if we want to reduce pressure.

5. What might be the most suitable title for the text?

A. Power of Tears B. How to Keep Healthy

C. Why We Cry D. A New Scientific Discovery

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。

The hole in the Earth's ozone layer (臭氧层) has until now protected Antarctica from the worst effects of global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3^oC on average, with melting ice contributing to a global sea level increase of up to 1.4 metres.

In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much of the continent surface colder than usual.

But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3^OC and a reduction in sea ice by around a third.

The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly. "Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent decades.

Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected - Antarctica may be a long way away but it is an important part of the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough, if it melts completely, to raise sea levels by 63 metres."

Even in a worse-case situation scientists don't expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 metres higher by the end of the century.

A. rapidly B. approximately C. contradictorily D. apparently

A. It is causing the ice to melt faster.

B. It is making much of the continent colder.

C. It is making the effects of global warming in the region worse.

A. Antarctica is currently experiencing the full effects of global warming.

B. The average temperature has increased by 3^OC in recent decades.

C. Antarctica contains most of the world's fresh water.
