Just hearing the name of the great white shar...

Just hearing the name of the great white shark makes people afraid. In fact， they have more to fear from us than we do from them. For many years， lots of great white sharks were killed.

But thanks to people’s efforts， the population of these sharks is rising again in the US， according to two recent studies.

Why is their growing population something to celebrate? Great white sharks play an important role in the ocean ecosystem. As the biggest predators， they help keep the population of other creatures from growing too large. If the population of an species(物种) gets too big， it will affect the food chain.

Although they are very important， great white sharks had been hunted for their meat and fins for a long time. In 1997， a law was passed in the US to stop the hunting of great white sharks. Gradually， the numbers of sharks started to increase.

The law wasn’t the only thing that has helped great white sharks. Environmental protection groups have also played a part. The research group， OCEARCH， puts an electronic device(装置) on a shark’s fin and then tracks(追踪) its movements. Just as important， they let the public follow each shark as it travels the world’s oceans. OCEARCH also gives each shark a name. The group’s most famous shark is a shark named Katharine. Thousands of people have tracked Katharine’s movements on the website. This helps people see sharks in a new way --- not just as the dangerous killers seen in movies. Learning about sharks makes people want to do more to protect them.

1. What is the good news mentioned in the second paragraph?

A. People can track sharks’ movements on a website.

B. The population of great white sharks is increasing.

C. Some new kinds of fish were found in the ocean.

D. Two recent studies show that great white sharks are not dangerous.

A. Their meant and fins are very valuable.

B. They can keep other ocean species away from danger.

C. Other Ocean species cannot live without great white sharks.

D. They can stop the population of other ocean species getting too big.

3.The underlined word， “predators”， in the third paragraph probably means “_________” in Chinese.

A. 捕食性动物　　　　 B. 素食性动物

C. 海洋生物　　　 D. 陆地生物

4.Which of the following statements is NOT true about OCEARCH?

A. It works hard to make people want to do more to protect sharks.

B. It helps thousands of people find their pets.

C. Its most famous shark is called Katharine.

Are you left-handed? If you are, you make up just 10% of the world’s population.1. Most people write and play musical instruments with their right hands.

Why are so few people left-handed? A new theory, called “cooperation (合作) vs competition” may have the answer.2.　　 When making tools for a right-handed person — like a knife — it was easier if everybody could use the same hand. But some humans wanted to compete instead. So to have an advantage over right-handed people, they would use their left hand to surprise competitors.

3.German born American scientist Albert Einstein, British physicist Isaac Newton and British biologist Charles Darwin are some famous “lefties”. At least six US presidents were left-handed, including Barack Obama, Bill Clinton, and Harry Truman.

“Lefties” are also often linked with creativity and visual (视觉) skills.

How can this be? Well, the left side of our brain is where we solve problems. The right side of our brain is where we develop creativity. Right-handers tend (倾向) to use the left side more than the right side.4.

“This is why there are more of them in creative areas, such as music, art and writing,” said Alan Searleman, PhD, from St. Lawrence University, New York.

5.They tend to have worse memories, often forgetting names and places.

Great white sharks have become well known in a bad way, for being scary. 　 1.　 . However, you are more likely to be hit by lightning than attacked by a great white shark.

One reason why people don’t like great white sharks is that they are huge. They grow to be nearly 21 feet long and can weigh up to 5,000 pounds. That is about two cars long! But the size is not typical. Most great whites are smaller, about 10 to 15 feet long. 　 2.　 .

Great whites are called apex predators（捕食者）because they are at the top of the food chain. They have no predators and aren’t that picky about what they eat. Great whites are known to eat fish, squid, other sharks, otters, turtles, dolphins, whales, seals, and sea lions.　 3.　 . Great whites also eat carrion, which is the remains of dead animals floating（漂浮）in the water.

4.　　 . They have 3,000 teeth, and each is up to 3 inches long! Their very sharp teeth are shaped like triangles and have rough edges that tear into things. Great whites don’t even chew their food. They just swallow it down. 　　 5.　　 .

But, like other sharks, great whites don’t intentionally（主动地）eat or attack humans. So swim without fear.

A. That’s still longer than one car, though

B. Those last two kinds are their favourite food

C. Movies and popular stories make them scary

D. A big meal can satisfy a great white shark for about two months

E. Another reason why people fear great whites is their frightening teeth
