What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist(牙医)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 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(细胞培养液).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(溶液)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(牙槽)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.

This passage is mainly about              .

A. how a dentist can save a knocked-out tooth

B. how to keep a knocked-out tooth healthy

C.how Dr.Courts and other researchers made their experiments

D.how to put a knocked-out tooth back into its socket

The best way to keep a knocked-out tooth healthy outside the mouth is to store it       .

A.in cell-culture medium    B.in milk     C.in water    D.in the open air

Milk can be used instead of cell-culture medium to put a knocked-out tooth in because     .

A.milk works better to keep the tooth healthy  B.milk causes less pain

C.cell-culture medium is not usually handy    D.cell-culture medium is more expensive

“Dr.Courts said that the best of al1 was to wash the tooth and put it right back into its socket in the mouth.”In the sentence, the word “best” means              .

A.cheapest and healthiest                  B.least painful and cheapest

C.quickest and least painful                D.easiest and healthiest

Today, we talk to an up-and-coming (有前途的) erhu player, Lee Hang, from Hong Kong. He’ll play with the Hong Kong Orchestra (管弦乐队) next Sunday in a special concert by young Chinese musicians.

Interviewer: Thank you for talking to us, Lee. You must be very excited.

Lee: Yes, I am. This is the first time that I’ve played with such a famous orchestra and in front of so many people. They’re expecting about 4,000 people.

Interviewer: Does that scare you?

Lee: To be honest, yes. I haven’t slept much in the last few days. But my teacher told me I wouldn’t take it seriously enough if I wasn’t scared. That helped a lot.

Interviewer: Tell me about why you started playing the erhu.

Lee: My parents took me to piano and violin lessons. I quite liked them but they had to force me to go sometimes. One night, I saw a documentary about Yo Yo Ma, the famous Chinese American cello(大提琴) player. He talked about his love of Chinese instruments and we should follow our interests. I always enjoyed listening to Chinese instruments like the erhu and guzheng. That inspired me to learn the erhu. My parents were glad that I was playing something I actually liked.

Interviewer: What do your friends think of you playing a Chinese instrument?

Lee: Well, a lot of my classmates think playing things like the erhu isn’t cool. I don’t care. It makes me happy. I got a letter from Yo Yo, saying how much he admired me and that he’d like to meet me next time when he’s in Hong Kong. They thought that was pretty cool!

Interviewer: And what does the future hold for you?

Lee: I’d like to study music in a university in China then hopefully play in orchestras. My ambition is to bring the beautiful sound of the erhu to all the corners of the world.

Interviewer: Well, if anyone can, it’s you. Thanks for talking to me, Lee. Good luck.

Lee: Thanks.
