听力原文： Objects that are vibrating make sounds．Rhythmic sound vibrations produce sound waves which travel in every direction．The frequency of a sound is the number of waves that pass a given point each second．The more rapidly an object vibrates，the greater the frequency of sound it makes．Frequency is measured in hertz．One hertz equals one sound wave per second．The frequency of sound determines the degree of highness or lowness of the sound．A high-pitched sound has a higher frequency than a low-pitched sound．Humans hear sounds that have frequencies from about 20 hertz to 20,000 hertz。Sound with a frequency higher than 20,000 hertz is called ultrasound which is too high-pitched for humans to hear．However，many animals can hear ultra- sound．Bats can hear higher sounds than any other animal．Some can hear up to 210,000 hertz．Bats send out lots of high-pitched squeaks and then listen to the echoes bouncing off things like insects．The shorter the time interval between the squeak and the echo，the closer they are to the insect．Using sound to find or“see” things is called echolocation．Another animal that uses ultrasound is the dolphin．Dolphins can hear sounds up to about 150,000 hertz．Dolphins use sound waves to find food underwater．They make clicking sounds that hit whatever is around them and then bounce hack to the dolphins．Dolphins can send as many as 2,000 clicks per second．Dolphins' ultrasound ability is so sensitive that they can detect small fish from 10 feet away．

(30)

A．The quicker it vibrates, the greater the frequency of sound it produces.

B．The slower it vibrates, the higher the frequency of sound it produces.

C．The quicker it vibrates, the lower the frequency of sound it produces.

D．The frequency of sound it produces is not in proportion to the speed it vibrates.

听力原文：（23) Almost 20,000 whales have been slaughtered since a ban on commercial whaling

听力原文： (23) Almost 20,000 whales have been slaughtered since a ban on commercial whaling was introduced in 1986 and the death toll is rising each year. Norway and Japan killed over 1,000 whales in 1999 and they plan to kill even more. The International Whaling Commission (IWC) has failed to stop the killing and a compromise deal may relax the ban allowing coastal whaling—condemning many thousands more whales to a cruel death. In 1994, the IWC created a whale sanctuary in Antarctic waters and many believed the battle to save the whales had been won. But Japan has ignored the sanctuary and along with Norway continues to defy the whaling ban. As the environmental concerns increase, whaling is no longer the issue as it was or deserves to be. With little public awareness of the increasing whale slaughter, there has been no pressure to stop it. Consequently, the political will to confront the whalers and .enforce the whaling ban has slipped away. Commercial whaling has devastated whale populations worldwide, pushing the entire species to the brink of extinction. (24) There is still great scientific uncertainty about the size and status of remaining whale populations. Whales are facing increasing threats to their survival including increasing toxic pollution, massive over-fishing, entanglement in fishing nets, boat collisions, habitat loss, ozone depletion and climate change. They need to be protected, not hunted. (25) Commercial whaling is appallingly cruel and unnecessary. It is morally indefensible. It should be condemned to history, to a time when sadly we knew no better!

23. What does the speaker say about the death toll of whales after 1986？

24.How does the speaker describe scientific knowledge of whale populations？

25.What is the speaker's attitude towards whaling？

(4)

A．It is lessening.

B．It is growing.

C．It hasn't changed.

D．It is slowly changing.

听力原文：The cost is going up for just about everything, and college tuition is no excepti

听力原文： The cost is going up for just about everything, and college tuition is no exception. According to a nationwide survey published by the College Board's Scholarship Service, tuition at most American universities will be on average of 9 percent higher this year over last.

The biggest increase will occur at private colleges. Public colleges, heavily subsidized by tax funds, will also increase their tuition, but the increase will be a few percentages points lower than their privately-sponsored neighbors.

As a follow up, the United Press International did their own study at Massachusetts Institute of Technology. At M.I.T., advisors recommended that students have $8,900 available for one year's expenses, including $5,300 for tuition, $2,685 for room and board, $630 for personal expenses, and $285 for books and supplies. Ten years ago the tuition was only $2,150. To put that another way, the cost has climbed 150 percent in the last decade.

An additional burden is placed on out-of-state students who must pay extra charges ranging from $200 to $2, 000, and foreign students who are not eligible for scholarships at state-funded universities.

On the brighter side, the survey revealed that college graduates are entering the best job market since the middle 1960s. Job offers are up 16 percent from last year, and salaries are good, at least for graduates in technical fields. For example, a recent graduate in petroleum engineering can expect to make as much as $20,000 per year. A student with a liberal arts degree might expect to make about half that salary.

(30)

A．Average tuition costs increased by 9 percent.

B．Average tuition costs increased by 15 percent.

C．Average tuition costs increased by 90 percent.

D．Average tuition costs increased by 150 percent.

听力原文：Lions are opportunists. They prefer to eat without having to do too much work. Wh

听力原文： Lions are opportunists. They prefer to eat without having to do too much work. When resting in the shade, they are also watching the sky to see what is flying by, and even in the heat of the day they will suddenly start up and run a mile across the plains to find out what is going on. If another animal has made a kill, they will drive it off and take the kill for themselves. A grown lion can easily eat 60 pounds of meat at a single feeding. Often they eat until it seems painful for them to lie down. The lionesses(the females), being thinner and faster, are better hunters than the males. But the males don't mind. After the kill they move in and take the best share.

Most kills are made at night or just before daybreak. We have seen many, many daylight attempts but only ten kills. Roughly, it's about twenty daytime attempts for one kill.

When lions are hiding for an attack by a water hole, they wait patiently and can charge at any second. The kill is the exciting moment in the day-to-day life of the lion, since these great animals spend most of their time, about 20 hours a day, sleeping and resting.

Lions are Social cats, and when they are having a rest, they love to touch each other. After drinking at a water hole, a lioness rests her head on another's back. When walking, young lions often touch faces with older ones, an act of close ties among members of the group.

(33)

A．Because lions are cruel animals.

B．Because lions are clever animals.

C．Because lions like to take every chance to eat.

D．Because lions like to take advantage of other animals.

M: What do you need them for？

W: There's so much stuff piling up in my dormitory room. If I don't do something soon, I won't be able to move in there.

M: Do you usually order from a catalog？

W: Sometimes. Why？

M: Oh, it's just in the history class today we were talking about how the catalog sales business first got started in the US.

A Chicago retailer, Montgomery Ward started it in the late 1800s. It was really popular among farmers. It was difficult for them to make it to the big city stores so they ordered from catalogs.

W: Was Ward the only one in the business？

M: At first, but another person named Richard Sears started his own catalog after he heard how much money Ward was making.

W: What made them so popular？

M: Farmers trusted Ward and Sears for one thing. They delivered the products the farmers paid for and even refunded the price of things the farmers weren't satisfied with. The catalog became so popular that some country school teachers even used them as textbooks.

W: Textbooks？

M: Yeah, students practice spelling the names and adding up the prices of things in the catalogs.

W: Was everybody happy about it？

M: That's doubtful. It was said they drove some small store owners out of business. Sears and Ward sold stuff in such large quantities that they were able to undercut the prices at some small family owned stores.

(27)

A．The necessity to keep everything in place.

B．Catalogs used as textbooks by country school teachers.
