On receiving my learner driver license a couple of months ago, I started driving lessons straight away. In New Zealand, the __33__ driving age is 15.

Our surroundings are being polluted faster than nature and man’s present efforts cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.

    What can explain and solve this problem? The fact is that pollution is caused by man, by his desire for a modern way of life. We make “increasing industrialization”(工业化)our chief aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the countryside into the cities, eager for the benefits of our modem society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.

Isn’t it time we stopped to ask ourselves where we are going and why? It makes one think of the story about the airline pilot (飞行员) who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.

Man cannot prevent the world from being polluted because___________.

A. the population of the world is increasing fast   

B. people use too many man-made materials

C. our technological achievements have grown in the last twenty years

D. we are producing more cars, trucks and buses

People crowd into the cities for___________.

A. they want very much to find well-paid jobs

B. they are anxious to enjoy the achievements of our society

C. they have become tired of their homeland

D. they have a strong wish to become industrial workers

The story about the airline pilot tells us that___________.

A. man knows where the society is going

B. people do not welcome the rapid development of modern society

C. man can do little about the problem of pollution

D. the speaker is worried about the future of our society

What does the  writer really want to say in this passage?

A. With tile development of technology pollution has become a serious problem.

B. Lower the speed of development to stop pollution.

C. It’s time we did something to reduce pollution.

D. As industry is growing fast, pollution is the natural result.

 

PART FOUR WRITING SECTION A

Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN 3 WORDS for each blank. The Chilean earthquake, measuring 8.8 – magnitude, which struck early Saturday morning, released 500 times the energy of the 7.0 – magnitude quake that hit Haiti last month, a geophysicist told CBS’ “The Early Show. ” Tsunami warnings were issued for much of the Pacific, including Hawaii, following the quake that struck near the Chilean coast.

“When the earthquake occurred, it moved the land and then it moved the water causing the tsunami,” said U.S. Geological Survey geophysicist Jessica Sigala. “And the coastal areas of Chile have already noticed the wave heights up to about 7 feet.”

Sigala said Hawaiians can expect to see the waves from this tsunami around 11:20 a.m. local time (about 4:20 p.m. ET). “So we have to wait and see how big the waves will be.”

“It's not so much the height [of the wave] but it's the width, it's how long the duration, and then it's also the speed at which it's traveling,” said co-anchor Kelly Cobiella “Correct me if I'm wrong, but these waves are traveling at the speed of a jetliner, about 500 miles per hour?”

“That's correct. It's a big block of water coming onto the land,” Sigala said. 

Chile has already experienced several aftershocks following the quake.

“Aftershocks are definitely a concern,” said Sigala. "We always see aftershocks with a large quake and a shallow quake, which this one was. And as of right now, we've located about maybe 15 aftershocks and those are of the larger kind. I'm sure they felt much more than that.”

“A shallow earthquake just means that it happened pretty close to the surface,” said Sigala. “And because of that the energy is really close to the surface, where all the buildings and people are.”

    50 deaths caused by aftershocks have been reported, according to the national emergency agency, adding the estimate casualties to 960.

It is hard to track the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior.

So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans.

Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.

Earth scientists announced at a news conference recently that they had used the system for closely

monitoring a deep-sea volcanic eruption （爆发） for the first time and that they plan similar studies.

Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures.

The speed of sound in water is roughly one mile a second—slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope （听诊器） does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.

81. The passage is chiefly about ____ .

A. an effort to protect an endangered marine species

B. the civilian use of a military detection system

C. the exposure of a U.S. Navy top-secret weapon

D. a new way to look into the behavior of blue whales

82. The underwater listening system was originally designed ____ .

A. to trace and locate enemy vessels

B. to monitor deep-sea volcanic eruptions

C. to study the movement of ocean currents

D. to replace the global radio communications network

83. The deep-sea listening system makes use of ____ .

A. the sophisticated technology of focusing sounds under water

B. the capability of sound to travel at high speed

C. the unique property of layers of ocean water in transmitting sound

D. low-frequency sounds travelling across different layers of water____

84. It can be inferred from the passage that____.

A. new radio devices should be developed for tracking the endangered blue whales

B. blue whales are no longer endangered with the use of the new listening system

C. opinions differ as to whether civilian scientists should be allowed to use military technology

D. military technology has great potential in civilian use

85. Which of the following is true about the U.S. Navy underwater listening network?

A. It is now partly accessible to civilian scientists.

B. It has been replaced by a more advanced system.

C. It became useless to the military after the cold war.

D. It is indispensable in protecting endangered species.
