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 (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 peoples 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.36. this passage is mainly abouta. how a dentist can save a knocked-out toothb. how to keep a knocked-out tooth healthyc. how dr courts and other researchers made their experimentsd. how to put a knocked-out tooth back into its socket37. dr courts tested a. man-made teethb. teeth dried in the open airc. teeth pulled for various reasonsd. teeth put back in their sockets38. the best way to keep a knocked-out tooth healthy outside the mouth is to store it_.a. in cell-culture mediumb. in milkc. in waterd. in the open air39. 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 healthyb. milk causes less painc. cell-culture medium is not usually handyd. cell-culture medium is more expensivebthe high noise of modern life may affect speech and language development in the very young, according to a study that found the auditory parts of the brains of young mice are slower to organize properly in the presence of continuous sounds.researchers at the university of california, san francisco, kept a group of rats in an environment of continuous background noise and found that their brain circuits that receive sound did not develop at the same speed as animals that were raised in a quieter environment.edward f. chang and michael merzenich made the study together and said the continuous noise delayed the organization of auditory neurons (听觉神经)during a critical(决定性的)two-to-three-week period after the rats were born.for rats in the quieter environment, the auditory cortex neurons during this period gathered into a smaller area and began developing a selective response (选择性的反应)to sounds.but for the rats in the noisy environment, this organization was slowed, causing a delay in the development of the ability to notice the difference between sounds. the researchers said it took three or four times longer for the rats raised in a noisy environment to reach the basic marks of auditory development seen in the rats in the quieter environment.although the rat is not a perfect model for what happens in humans, the researchers note, the study does suggest that high levels of noise might possibly have a bad effect on babies language learning.these findings suggest that environmental noise, which is commonly present in modern life when we bring up babies, can lead to auditory and language-related development delays, the researchers write in science.the researchers noted that although the brain development was delayed in rats in the noisy environment, their brains did eventually reach full natural growth and development.40. the rats raised in an environment of continuous noise_.a. are backward in developing their brainsb. have brains smaller than othersc. cant receive sounds at alld. are used to the environment41. which of the following statements is not true according to the text?a. noise delayed the organization of auditory neurons.b. noise delayed the development of the ability to hear sounds.c. in modern life there is too much noise for the young to grow up well.d. too much noise has a bad effect on old rats.42. it took _ for the rats raised in the noise to reach the bas
