轉折關系

　　解題技巧：
　　轉折關系常涉及讓步狀語從句或轉折并列句的理解。讓步狀語從句通常由while或although引導，通常強調的是主句的內容;在轉折并列句中，表示轉折的詞有however,nonetheless,but,yet,on the other hand等，強調的是轉折連詞后面內容。
　　練習：
　　As we heve seen, the focus of medical care in our society has been shifting frome curing desease to preventing disease — especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
　　Q: In the paragraph, people are reminded that ______.
　　A. good health is more than not being ill
　　B. drinking,even if not to excess, could be harmful
　　C. regular health checks are essential to keeping fit
　　D. prevention is more difficult than cure
　　答案:
　　選A。本段最后一句是對倒數第2、3句的轉折。這個人沒病，但是還可以更健康。所以良好的健康不僅僅是生病，A正確表達了這個含義。
