识别高考阅读理解干扰项的七大法宝

检验：根据原文中的“parallel”（与…平行）可以确定上述分析结果正确。

5．常识项原则

在议论文当中，那些符合一般常识，意义深刻富有哲理，符合一般规律，属于普遍现象的选项往往是正确答案。

Trees are useful to man in three import ways: they provide him with wood and other products; they give him shade; and they help to prevent droughts and floods. Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important.

Q: What is the most important service of trees to man according to the passage?

A. They help him make money

B. They give him wood and other products

C. They help him prevent droughts and floods

D. They give him shade

『个案解析』：答案为C，这是常识项。植树造林是我国的一大国策，目的在于防止洪涝、风沙、旱灾，这是我国公民的普遍常识，所以C为正确答案：树木可以帮助人类阻挡洪涝与旱灾。相对于其它三项，C项意义更加深远。 其实，根据“Unfortunately（语义转折标志），in many parts of the world, man has not realized that the third of these services is the most important，”我们也可以得出C项为正确答案。

再如：

If Mrs. Abby dies after he has paid premiums for one or two years only, the insurance company will lose heavily. But if she lives to the age of seventy or beyond, the insurance company will make a profit.

Q: According to the passage, the insurance company will make great profits.

A. If the premium（保险费）is increased so the company can earn more money  each year.

B. If nobody above seventy buys insurance against death.

C. If most insurance buyers live longer than the average length of life.

D. If most insurance buyers live shorter than the average length of life.

『个案解析』：答案为C，这也是常识项。众所周知，保险公司之所以能盈利，那是因为被保险的对象平安无事，所以，人活得越长，他交的保险额就越多，保险公司利润就越高，所以C为正确答案：如果投保人比普通人活得更长。

注意：人的平均年龄往往是保险公司设置保率的基准。另外，此题根据“But （语义转折标志）if she lives to the age of seventy or beyond, the insurance company will make a profit.”也可以推断出答案为C。

6．集合项原则

四个选项中，如果有一项是其它两项或三项的集合，那么此集合项往往就是正确答案。

其表现形式为：A and B; A, B and C; Both A and B; all of the above items。

The Antarctic is a continent almost as large as Europe and Australia combined, surrounded by the most unobstructed water areas of the world- the Atlantic, Pacific, and Indian Oceans.

Q: Antarctic is bordered （与…接壤） by the ____.

A ） Atlantic ocean

B） Pacific Ocean

C） Indian Ocean.

D） All of the above
