17．We can stay young forever．That is the message Dr．Shen Ziyin wants to give the world．And the Chinese doctor claims that he has found an answer to the problems of aging．
His solution is a herbal medicine to slow the process of aging．
Dr．Shen Ziyin has been trained in Western medicine．At the same time he studied traditional Chinese medicine．And，he has been working for the past forty years to put together the best of both and find a cure for aging．He has taken a hint from the ancient Chinese medicine system called"shen"．
According to Shen，it is the kidney which adjusts the functioning of the body as well as its aging process．It is responsible for the level of activity that the human bodies go through．Studies conducted by Dr．Shen show that herbal medicine based on the shen system slow the aging process，says a report in The Telegraph newspaper．
We notice that when people grow old，they have reduced strength，loss of hair，backache，weakness in general，and wrinkles，among others．This happens because when people grow old，their bodies produce T-cells．These T-cells contain a particular substance called Fas．Fas makes the cells in the body destruct themselves．
So the only way to slow down aging is to slow the production of T-cells in the body．This can happen if people eat low calorie food．Then the body is not active enough to produce extra T-cells．But，is going hungry all the time a good price to pay for staying young？
This is where Dr．Shen's herbal medicine comes in．But how effective it will be，only time can tell．

分析 本文主要講述了沈子銀醫(yī)生發(fā)現(xiàn)人體老化的問題的答案．他的解決方案是一種延緩衰老的草藥．沈子銀博士已經(jīng)在西方醫(yī)學訓練，同時他學習中醫(yī)．在過去的四十年里他一直工作是為了把中西醫(yī)兩者最好的結(jié)合和找到對老齡化的治愈．根據(jù)沈的說法，腎臟調(diào)節(jié)人體功能和變老過程，它負責人類的活動水平．最后經(jīng)過一系列的研究得出延緩衰老的唯一方法是減慢體內(nèi)T細胞的產(chǎn)生．如果人們吃低卡路里的食物，那么身體就沒有足夠的活力來產(chǎn)生額外的T細胞．
解答 9．D 細節(jié)理解題，由第二段Dr．Shen Ziyin has been trained in Western medicine．At the same time he studied traditional Chinese medicine．And，he has been working for the past forty years to put together the best of both and find a cure for aging．可知他是結(jié)合中西醫(yī)來延緩人的衰老．故選D．
