Ears are for hearing — everyone knows that. But for a creature called the Cuvier’s beaked whale, hearing starts in the throat (喉嚨), a new study found.
The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar (聲吶). This sonar, used by some ships, sends out sound waves to locate underwater objects.
The Cuvier’s beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they’re 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X rays of two Cuvier’s beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier’s beaked whale’s head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure (構(gòu)造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (墊) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale’s head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal’s jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal’s ears.
69. Toothed whales look for food under the sea by ______.
A. watching the shape and size of their objects B. diving deep into the sea
C. sending and receiving sounds D. making lots of noises
70. Researchers took X rays of two Cuvier’s beaked whales in order to ______.
A. find out why they had died and washed up on the beach
B. make a computer model of a Cuvier’s beaked whale’s head
C. make sure that sound travels through the head
D. know more about the way the whale hears
71. Which of the following describes the way taken by sound waves through a Cuvier’s beaked whale?
A. A hole in the back of the jaw → the ears → the jaw → the throat.
B. The jaw → the throat → a hole in the back of the jaw → the ears.
C. The throat → the jaw → the ears → a hole in the back of the jaw.
D. The ears → the throat → a hole in the back of the jaw → the jaw.
72. Which of the following is TRUE according to this passage?
A. The throat is important to the Cuvier’s beaked whale’s hearing.
B. Ships send out sound waves like a Cuvier’s beaked whale.
C. The ears are actually useless to the Cuvier’s beaked whale.
D. The researchers haven’t found how the whales hear.

If you’re a male and you’re reading this, congratulations! You’re a survivor. According to statistics,you’re more than twice as likely to die of skin cancer than a woman,and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term,about 78 years for men in Australia,you’ll die on average five years before a woman.
There're many reasons for this--typically,men take more risks than women and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor.
“Men aren't seeing doctors as often as they should,” says Dr. Gullotta.“This is particularly so
for the over-40s, when diseases tend to strike. According to a recent survey, 95%of women aged between 15 and early 49s see a doctor once a year, compared to 70%of men in the same age group.
“A lot of men think they’re unbeatable,”Gullotta says.“They only come in when a friend drops dead on the golf course and they think, Geez, if it could happen to him …”
Then there’s the ostrich(鴕鳥)approach.“Some men are scared of what might be there and would rather not know,” says Dr. Ross Cartmill.
“Most men get their cars serviced more regularly than they service their bodies,” Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups.
“Prevention is cheaper in the long run than having to treat the diseases.Besides, the final cost is far greater,it’s called premature death.”

Researchers in Britain are driving the environmental movement to a new level. A team from the University of Warwick has built what it calls the world’s first completely environmentally friendly Formula Three racing car.
The car is made mainly of renewable materials, like plants and vegetables. The structure around the car is made from natural plant fibers and potatoes. The steering wheel(方向盤) is made from root vegetables like carrots. The engine uses bio-fuel made from vegetable oil and waste chocolate.
The new racing car is extremely fast. The car has a top speed of two hundred fifteen kilometers an hour. And it can go from zero to ninety-five kilometers an hour in just two and a half seconds. The racing car meets all of the Formula Three racing requirements except for its biodiesel(生物柴油) engine.
Automobile racing is one of the most widely watched sports in the world. But it is also considered one of the least friendly sports to the environment. Racing cars burn a lot of fuel, and create a lot of air pollution. In recent years, the racing industry has taken steps to protect the environment. More racing companies are now producing cars that use less energy. These cars produce less pollution than cars that depend on traditional fuel, like gasoline.
Last month, the new racing car was set to run in its first competitive race at the Formula Three Championship Final at Brands Hatch. It would have been the first biodiesel-powered car to race at Formula Three. Current Formula Three rules let only gasoline-powered car to compete. Officials needed permission from all of the Formula Three racers for the biodiesel-powered car to compete. They were unable to contact one of the drivers, so the new racing car didn’t appear in the event. In test runs, the new racing car was the fifth fastest among the Formula Three race cars. Supporters are hoping to have the fuel problem solved in time to compete in the next season.
【小題1】. What’s the second paragraph mainly about?
A.What materials the new racing car is made of. |
B.Why researchers built the new racing car. |
C.The characteristics of the new racing car. |
D.The process of the new racing car being designed. |
A.speed | B.a(chǎn)ppearance | C.weight | D.engine |
A.the new racing car is the first environmentally friendly car |
B.a(chǎn)utomobile racing could be forbidden in the near future |
C.many people like to watch automobile racing |
D.the new racing car will be allowed to compete in the next season of Formula Three racing |
A.burn more fuel | B.go more quickly |
C.produce less pollution | D.cost less money |
A.Because the new racing car still needs testing. |
B.Because officials needed each racer’s permission but failed to contact one. |
C.Because there’re some technical problems to be solved. |
D.Because few drivers think it is fast enough. |
