【题目】For years,Hagelin has studied what role scents(气味)play in wild birds’ behavior.In 2010,Hagelin heard Jan Straley,a marine biologist,talk about the behavior of whales.Straley mentioned that whales often leap into the air,but nobody knew why.

The mystery interested Hagelin.So Hagelin asked Straley whether they might leap to smell the air—maybe to locate food or look for danger.Straley replied that it was an interesting idea but there wasn't much evidence that whales have a sense of smell.To investigate the idea further,the two scientists teamed up.

In the summer of 2011,they set up a post on the coast of southern Alaska.The researchers spent hours monitoring the direction of the whales and of the wind.The whales headed into the wind half of the time.This didn't prove that whales leap to smell,but it suggested that it is possible.

Meanwhile,other researchers in Alaska were studying a region of the brain called the olfactory bulb(嗅觉球)in whales.Olfaction means the ability to smell.Humans also process smells in the olfactory bulb.

In identifying a scent,you might think the nose does all of the work.However,the major role of a nose is to draw chemicals on the air and pass them across sensing cells.As chemicals come into contact,they give signals that travel directly to the bulb and then in the brain for further interpretation.

The researchers discovered that the bulb in a whale was more complex than the one in a human.In whales,this smell-processing center takes up a share of the brain six times larger than it does in humans.

The brain research suggested that whales probably can smell just as well as people—and possibly better than humans can.It is supposed that a good sense of smell could help them find food more easily.

However,Hagelin is not sure of that.Now he is planning a new study that will examine whether whales do use the sense of smell to find food.

1Hagelin and Straley set up a post with the purpose of finding______.

A. how whales look for food in groups

B. whether whales can get out of danger

C. how whales head into the wind

D. whether whales leap to smell the air

2We can learn from the text that the olfactory bulb in a whale______.

A. is smaller than the one in a human

B. draws chemicals spreading in the air

C. is more complex than the one in a human

D. processes smells better than the one in a human

3It is implied in the text that Hagelin______.

A. hasn't got any evidence that whales have a sense of smell so far

B. doesn't know whether whales hunt their food in groups

C. isn't sure that the sense of smell can help whales find food

D. isn't sure whether humans can smell as well as whales

4In which section of a newspaper can we read this text?

A. Education. B. Science.

【题目】根据短文理解,选择正确答案。
Woman Uses Daughter's Key to "Steal" Car
Charlie Vansant, a college student of Athens, Ohio, who reported that his car was stolen, got a surprise when he learned a woman had mistaken it for her daughter's car and taken it — using her key.
Kate Anderson became an accidental car thief when picking up her daughter's car near an Ohio University building last week. Anderson spotted the Toyota Camry(丰田凯美瑞)and used her daughter's key to unlock the car, start the engine and drive home — without realizing that the car wasn't her daughter's.
When Charlie Vansant left class a short time later, he found only an empty parking spot. He first assumed the car had been towed, but when the police couldn't find a record of it, they took a theft(偷窃) report.
The morning after Anderson took the car, her daughter discovered the Camry in the driveway wasn't hers. Anderson said she was able to find Vansant's name on paperwork in the glove compartment and look up his phone number on the website for the university.
When Anderson told Charlie the car was in her driveway, "It sounded really suspicious at first, as she wanted to hold the thing for ransom (赎金) , ” said Vansant. He eventually went to the house with a police officer, where he was reunited with his car. According to the police report, the case was closed "because of mistaken car identity", and Anderson wasn't charged.
Vansant seemed to blame the car company more than the "thief". "Her key fit not only my lock, but my ignition(点火装置)as well — so high-five for Toyota, I guess." he said.
(1)What does the underlined word "towed" mean in paragraph 3?
A.sold
B.damaged.
C.remove
D.stolen.
(2)Which of the following is NOT true according to the passage?
A.Mrs. Anderson's daughter discovered the car her mother drove was not hers.
B.Mrs. Anderson stole Charlie's car at the request of her daughter.
C.Charlie had thought he had to give Anderson money to get his car back.
D.Mrs. Anderson used her daughter's key to unlock Charlie's car and drive home.
(3)What does Charlie mean by "high-five for Toyota"?
A.He should thank Toyota for returning his car.
B.He thinks highly of Toyota for producing large quantities of cars.
C.He wants to celebrate with Toyota for getting his car back.
D.He is blaming Toyota for the poor quality of car keys.
(4)What is likely to happen next according to the passage?
A.Mrs. Anderson was charged with stealing a car.
B.Charlie blamed Mrs. Anderson for mistakenly taking his car.
C.The Toyota Company would give Charlie a new car as compensation.
D.Charlie would ask the Toyota Company to give him an explanation.
