31. What do your muscles need when you run? 32. Why are people always curious? Passage Three

What do you do if you are hit in the mouth and one of your teeth is knocked out? Band Three 173

A dentist may be able to put the tooth back in for you, but you have to get to the dentist

first. In the meantime, you have to store the tooth so that it will stay healthy. The simplest thing to do is to put the tooth back into your mouth, or you could put it in milk. Frank Courts, a dentist at the University of Florida, worked with other

researchers to find the safest way of keeping knocked-out teeth. He tried putting teeth

into milk, into water, and into cell-culture medium. He also tried just drying the teeth in the open air. He used teeth that had to be removed from people’s mouths for various reasons. The teeth were put into one of the solutions or stored in the air for one hour.

Then cells from the root of the teeth were scraped off the teeth. Dr. Courts and the

others then studied how healthy these cells were.

The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth. However, few people keep cell-culture medium handy at home or in school. The next best thing was milk. But Dr. Courts said that the best thing of all was to wash the tooth and put it right back into its socket in the mouth. For some people, though, this is just too painful or upsetting. So milk will do, until you get your tooth (and your

mouth) to a dentist.

Questions 33 to 35 are based on the passage you have just heard. 33. What is the passage mainly about?

34. What is the best way to store a knocked-out tooth healthily outside the mouth?

35. What did Dr Courts test on? Section C: Compound Dictation

Directions: In this section, you will hear a passage three times. When the passage is read for the first time,

you should listen carefully for its general idea. When the passage is read for the second time,

you are required to fill in the blanks numbered from 36 to 43 with the exact words you have

just heard. For blanks numbered from 44 to 46 you are required to fill in the missing information.

For these blanks, you can either use the exact words you have just heard or write

down

the main points in you own words. Finally, when the passage is read for the third time, you

should check what you have written. Immigration: New York

New Yorkers like to call their city “the capital of the world”. The results of a

new (36) population survey show that even if the name is perhaps a little too (37) ambitious, the city (38) definitely may claim to be the world in (39) miniature. Two out of every five New Yorkers were born outside the United States. That (40) figure is based on the results of a citywide (41) survey of more than 15 thousand (42) households conducted by the United States Census Bureau. Andrew Beveridge, a sociologist who analyzed the data, says the foreign-born population in New York has increased (43)dramatically during the last 10 years.

In 1990, the census (44) estimates show about 28 percent immigrants in New

York City, and in the 1999 survey you get about 40 percent immigrants. If you look 174 Model Test (2)

at it with respect to households headed by immigrants, it is actually 44 percent. (45) New York’s immigrant population is highly diverse. For example, the city’s borough of Queens is considered the most diverse county in the United States. (46) People representing 167 nationalities live there, speaking 116 languages. However, Mr. Beveridge says, there are several groups that dominate immigration to the city such as Dominicans (387,000), Russians (229,000), Chinese (192,000) and Mexicans (133,000). Band Three 175

Key to Model Test (3) Band Three Part I. Writing Sample Writing:

Diligence Is the Key to Success

All people dream of being successful in what they are doingDiligence Is the Key to Success

All people dream of being successful in what they are doing. Some of them think talent plays a critical role in people’s success while others argue they obtain their success

because they have good luck. In fact there is more than one way to success. But we can

see almost all successful people have one thing in common—they all have made great efforts to make their dreams come true.

There is an old saying that success belongs to those people who are well- prepared, which means if one wants to be successful, he must work hard. To put it in a different way, in spite of good luck, one cannot actually succeed if he doesn’t make efforts. An

artistic talent will not turn into a great artist if he doesn’t practices every day. A scientific

genius will not become a scientist if he doesn’t spend much time and energy observing and experimenting with things around him. All these have proved that diligence, instead

of luck or talent, is the key to success.

As for me, I strongly contend that success depends on diligence. No pains, no gains. If we want to succeed, the only way for us is to work hard. Remember, diligence is

the key to success.
