1.不知道你们老师给你们讲过没有,在时间状语中,当主句是将来时的时候,从句一般不用将来时,要用一般现在时或现在完成时代替一般将来时。这一题中,sb. is to do sth.是表示未来的一种行为的。2.这题我觉得是表示一个习惯吧 。。因为列车发车的时间是固定的吧。。或者这一题我觉得也可以用上一题的观点来解释,因为虽然是问的can you,是一般现在时,但是回答却是未来的事情,所以这里的can you 我觉得可以相当于是will you ,额。。所以。。。

1.Peter is to study medicine when he __ middle school。A.will finish B.has finished C.finished D.would finish本题考查的是时间状语从句,从句中的时态应遵循“主将现从”。主句is to study是将来时,从句要用现在时,所以选择B。另外,B选项的时态为现在完成时,这是因为study medicine的前提是finish middle school,从时间上在其之前,所以要用完成时。2.----Can you tell me when the train __(leave) for Shanghai.----Of course,Ican.It left half an hour ago.用leaves这种一般现在时表示这趟列车的一般行为,就是每天都是这个时刻发车的。will leave是一般将来时,时态错误。而且如果要选择will leave,从句中的顺序也应为:Can you tell me when will the train leave for Shanghai。

1 : 你可以这样理解,Peter是先在中学毕业,再去学医。所以中学毕业要用完成时态 2:“leave” 是在从句后面,从句不能用将来时 (仅供参考,我只是中学生,不是老师)

The purpose of Natural Medicinal ChemistryFrom natural medicines in the research and development of new drugs (including the lead compound of structure modification and transformation, the total synthesis), which our study of natural medicines are the main purpose of the chemical. Pure compounds to develop new drugs is very difficult, long cycle and the high cost of chemotherapy side effects, and easy to produce drug resistance, cause injury to human health, and from green plant life of the natural active ingredients often have high security, so to natural medicine as raw materials of drugs and drug extracts in the world is increasingly popular(1) a wide range of natural products, novel structure, pharmacological screening of the hit rate than the high synthetic compounds derived from natural lead compounds promising treatment for difficult cases of new drugs, so drugs from the natural development of new drugs has become a Top research directions. It was predicted that the future of natural drugs and chemical substances will be evenly divided, and biology were the three drugs with a tendency(2) A number of natural active compounds, because there are some defects, such as efficacy is not satisfactory, or side effects must exist, or because the content is too low, shortage of resources, it is difficult to Medium derived from natural raw materials, or because the structure was too complex, synthetic is also very difficult, so there is no direct the development and utilization of their own future. However, the natural active ingredients for the lead compounds, structural modification or structural alteration, and eventually developed into new drugs. For example: synthetic morphine substitutes - is scheduled for piperaquine (meperidine), morphine is retained in the structural parts of an effective (analgesic effect of the same!), And its addictive than morphine decreased. Another example: the active ingredient in coca leaves cocaine has a very strong narcotic effect, but toxic, easy to addiction, through research design and synthesis of local anesthetics such as procaine. Again Example: to extract from the Artemisia annua with the separation of anti-malarial activity of artemisinin, is a heat-labile compounds, such as its hydrogenated, methylated derivatives artemether made after the markedly improved stability, anti - more enhanced malaria activity. 问题补充的翻译:In the 21st century, "return to nature" of the world trend, the traditional medicine once again full of great vitality and show broad prospects for development. Western medicine sector has changed the original opinion, interested in Chinese medicine to Chinese medicine in Japan, Germany, the United States and other Western developed countries has been given scant attention up.World Association of Traditional Chinese Medicine in 1994, set up in Los Angeles, the West has also opened a number of institutions of higher learning professional courses on Chinese medicine or the establishment of a Chinese medicine research center. The United States Food and Drug Administration (FDA) have begun to formally accept the traditional Chinese medicine compound products. This trend of Chinese medicine into the world to provide an unprecedented good opportunity. Modernization of Traditional Chinese Medicine is the inevitable trend of the modernization of Chinese medicine must be to the world and the benefit of mankind. The development of Chinese medicine is the medicine our country in the competition to win one of the effective ways.

(2) is not the natural activity compound short, because of existence some defects, existence definitely poisons or a side effect, or resource shortage, is difficult to draw materials from natural raw material middle because contents are very low,or excessively, complicated , compose because of structure if pesticide effect is not ideal, also very difficult , develop the future making use of therefore self is not direct. And but take natural activity component as guide compound, the structure being in progress polishes or structure reforms, ultimate exploitation becomes a new drug.For example: The cries of a baby replaces the morphine combining substitution- stablely (dolantin) , (the effect is invariable now that effective in having reserved morphine structure part eases pain)! ,Use whose more obvious than morphine habituation sex lessening. Such as: In Gukeye, active constituent cocain has the very strong anaesthesia effect, but big , easily able addiction of toxicity, by studying the ethocaine designing the anaesthetic having composed waits. No matter how regular: Active Artemisia apiacea is plain from the malaria extracting having parting for in Artemisia apiacea resisting , is one kind of hot unsteady compound, the stability improves obviously after manufacturing the Wormwood A ether derivative if hydrogenate with the person , methylate,resist malaria activity strengthening especially.
