[不定项选择题]共用题干 Brain Drain

1.Brain drain is a phenomenon under which"people of a nation move to another nation due to financial benefits and also due to economical reasons,but there are many more reasons behind it". If we think deeply to the topic,we would find that this phenomenon has more disadvantages than advantages.
2.This phenomenon has many advantages for receiving countries which will automatically benefit from the skills and talents of immigrated people who were educated and qualified in their home countnes.
3.However,developing countries are deeply affected by this phenomenon since they are deprived from millions of their skilled workers, doctors,hardworking Engineers,and billions of man power. Those elites represent the backbone of their economies and once they travel abroad,their economies will not flourish and promote.In fact,there are many reasons behind brain drain.Firstly,the Government is the first responsible for brain drain. The salaries paid by local companies are much less than multinational foreign companies,which pushes millions of intelligent,hardworking Engineers to leave their native countries to look for a better life and opportunities.Secondly,the status and facilities provided by foreign companies are much higher in quality and quantity.Also,some people find it a matter of pride and dignity to work as an employee in foreign countries.
4.But we have to mention that brain drain does not only affect developing countries but also has some advantages for them.People living abroad help foreigners to know about their cultures and traditions.Also,they give information about various natural beauties and tourist spots in their home countries,which encourages tourists to visit them. This in turn increases tourist income.Brain drain also helps in increasing their foreign exchanges.
5.But at last you would find that brain drain has more disadvantages than advantages on developing or poor countries.So,to stop brain drain,local governments should make people aware of its harmful effects.Also Government should provide opportunities to their elites and should provide them with handsome salary so that they can serve their own mother nation. Paragraph 4______
A.Harmful effects of brain drain on developing countries.
B.Brain drain in developing countries.
C.Strategies governments can use to curb brain drain.
D.Good effects of brain drain on receiving countries.
E.Brain drain and elites.
F.Benefits brain drain brings to developing countries.

[单项选择]

阿托生是美国运用最广泛的一种除草剂，除草效果明显，然而让它混入饮用水后，其危害极大。除完草之后残留在土壤中的阿托生会和土壤融为一体，并不会再流走。残留的阿托生会进入地下水源，造成更为广泛的危险。从动物实验可以看出，量多的阿托生损害肝、肾、肺或心脏，它还可能是一种致癌物质。美国印第安纳州珀杜大学的科学家找到了一种能吃掉阿托生的微生物。他认为该微生物虽不能用于净化被阿托生污染的水源，但可以在阿托生混入水源之前在土壤中使其转化为无害物质。实验室试验相当成功，该微生物可以在150天内消86%的阿托生。

该文支持的主要观点是（）
A. 美国除草剂阿托生的弊端
B. 美国科学家找到一种专吃残留农药的微生物
C. 微生物的新用途
D. 美国科学家已成功防止阿托生污染水源
