听力原文：W：Hi，Mike! You missed a great history lecture this morning．Where were you？

M: Oh, I overslept again. This really is becoming a bad habit. What did Professor Brown talk about today？

W: Can you believe it？ We talked about George Washington's false teeth.

M: All I know is that they were made of wood.

W: A professor at a dental school in California recently presented a paper showing that Washington's teeth were made of many things, including, can you imagine, elephant ivory and cow's teeth, but not wood.

M: But why do people say Washington's teeth were made of wood？

W: A set of his teeth that were made of elephant ivory were shown publicly at various exhibitions about a hundred years ago. The ivory had turned a very dark color, and I guess, looks like wood.

M: Yes, I've seen some ivory that was dark brown color.

W: It seems that ivory turns dark easily with age, especially if it's exposed to drinks, such as coffee, tea, or wine. I guess that's how the story got started.

M: What's about cow's teeth？

W: You know cows have teeth just on their bottom jaws. After about five years of biting grass off against their hard up- per jaws, the bottom teeth wear down into the shape of a human tooth.

(23)

A．A student and a professor.

B．Two students.

C．Two dentists.

D．A dentist and a patient.

听力原文： How many teeth have you had failed in the past two years？ If you follow the advi

ce of Dr Forsdic, you may be able to reduce the number of your visits to dentist. Dr Forsdic conducted a two-year survey to find out how to prevent or reduce dental decay. 946 students took part in the experiment. 523 students cleaned their teeth within 10 minutes of eating. When possible, they used the tooth- brush. When this was impossible, they washed their mouth thoroughly with water. The remaining 423 students merely cleaned their teeth when they went to bed and when they got up in the morning. All the students had their teeth X-rayed at the end of the first and second years. At the end of the first year, the night-and-morning group had 3 times as many decayed teeth as the clean-after-each- meal group. At the end of the second year, the latter group had 53% fewer decayed teeth than the former group. Dr Forsdic has cleaned his teeth after every meal for 13 years and has not had a single decayed tooth. He pointed out that sugar is a major agent in dental decay. Particularly the sugar in sweets, cakes and soft drinks. Ideally, you should keep a toothbrush in your pocket and use it immediately after you have finished eating. When this is impractical, you can at least make sure that you have a drink of water and let the water through your teeth to force out any particles of food. Seven out of ten people lose at least half their teeth by the time they are 50. Many have a complete set of false teeth by that time. In any case, neither toothache nor a visit to a dentist is very pleasant. So it is worthwhile making an effort to keep your own teeth as long as possible. The main preventative agent is simply water.

According to the passage ,what type of food/drink is most likely to cause dental decay？

A．Coca Cola

B．Sausage.

C．Milk.

D．Fried chicken.

听力原文： The office has always been a place to get ahead. Unfortunately, it is also a place where a lot of natural resources start to fall behind. Take a look around next time you're at work. See how many lights are left on when people leave. See how much paper is being wasted. How much electricity is being used to run computers that are left on. Look at how much water is being wasted in the restrooms. And how much solid waste is being thrown out in the rubbish cans. We bet it is a lot.

Now, here are some simple ways you can produce less waste at work. When you arc at the computer copier, only make the copies you need. Use both sides of the paper when writing something less important. Turn off your lights when you leave. Use a lower watt bulb in your lamp. Drink your coffee or tea out of your mug instead of single-use cups. Set up a recycling box for cans and one for bottles. And when you're in the bathroom brushing your teeth or washing your face, don't let the tap run. Remember, if we use fewer resources today, we'll have more for tomorrow.

(33)

A．The disadvantages of working in an office.

B．The waste produced in an office.

C．To save resources when working in an office.

D．How to save water in a restroom.

听力原文： Washoe is a young chimpanzee. She is not ordinary chimpanzee, though. Scientists

are doing a research on her. They want to see how civilized she can become. Already she does many things a human being can do.

For example, she has been learning how to exchange massages with people. The scientists are teaching her sign language. When she wants to be picked up. Washoe points up with one finger. She rubs her teeth with her finger when she wants to brush her teeth. This is done after every meal.

Washoe has also been trained to think out and find answers to problems. Once she was put in a room with food hanging from the ceiling. It was too high to reach. After she considered the problem, she got a tall box to stand on. The food was still too high to be reached. Washoe found a long pole. Then she climbed onto the box, grasped the pole, and knocked down the food with the pole.

Washoe lives like a human, too. The scientists keep her in a fully furnished house. After a hard lesson in the laboratory, she goes home. There she plays with her toys. She even enjoys watching television before going to bed.

Washoe is a(n) ______ chimpanzee.

A．young male

B．old male

C．young female

D．old female
