16．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 本文介紹了Dr．Shen在幾十年中，通過中西醫(yī)結(jié)合的方法，研究并發(fā)現(xiàn)了人變老的原因，推出了自己獨特的中藥來延緩衰老．根據(jù)Dr Shen的理論，人變老是由于人體的腎臟器官會隨著年齡的增長而產(chǎn)生一種T-cells，如果想延緩衰老就要減少T-cells的產(chǎn)生．但是這種理論還有待于證實．
解答 28．D 細(xì)節(jié)理解題．從文章第三段And，he has been working for the past forty years to put together the best of both and find a cure for aging．可知他是通過中西醫(yī)結(jié)合研究出了人變老的奧秘．所以D選項正確．
29．B 細(xì)節(jié)理解題．文中提到 it is the kidney（腎臟）which adjusts the functioning of the body as well as aging process，腎臟調(diào)節(jié)人體的功能以及變老的過程，由此可知B為正確選項．
30．B 細(xì)節(jié)理解題．從文章倒數(shù)第三段可知This happens because when people grow old，their bodies produce T-cells．因為人變老的時候，他們的身體產(chǎn)生T-cells．所以B選項正確．
31．C 推理判斷題．從文章末句 But how effective it will be，only time can tell．可以判斷作者不能確定效果，藥物如何還需要時間的檢驗，所以C選項正確．
點評 本篇文章主要是細(xì)節(jié)理解方面的題型，需要考生通過跳讀迅速找到對應(yīng)的句子進行詳細(xì)理解，句子的理解可以結(jié)合上下文意思，通過邏輯推理得到．
