资源描述
是非判断题是细节题的一种，是要求考生选出与文章内容相符(三误一正)或不相符(三正一误)的一项。题干中常有TRUE, NOT true或EXCEPT等，考生务必要留意是否有NOT或EXCEPT，否则就容易出错。常见的提问方式有： 1. Which of the following statements is (NOT) true? 2. The author mentions all of the items listed below except. . .,如何做是非判断题,信息点可能在某句、某段，较容易；但信息点也可能分散在几段甚至全文，相对就较难了。当分散在几段或全文时，按理需要花较多时间在各段落找到相关句。若要到全文中去一一查证四个选项，效率太低。因此我们可以首先对所有选项作逐一分析，根据常理或自己的知识结构，看看哪一选项最有可能是答案。如问哪一个true，就把四个中最可能正确的一项挑出来首先去查证；如问哪一个NOT true，就把四个中最可能是错误的一项挑出来首先去查证。用这一方法，最多查证两项，答案就会出来。,另外还有一招，假如我们发现四个选项中有两个选项的意思矛盾或相反，那么其中之一很可能是正确答案，就立马排除了另两个选项，只需从两个选项中选一个去验证。这样不但节省了时间，更大大提高了正确率。,阅读下列文选，然后从所给的A、B、C和D项中，选出最佳选项。 1.Which of the following is true according to the passage? A. Dogsledding is the most popular sport among local people. B. Watching wildlife is a memorable experience. C. Travellers should bring their own sports equipment. D. Shopping is too simple a pleasure to enjoy.,即学即用,B,B 分析四个选项，最有可能正确的是选项B，由文中“Wildlife watching also creates satisfying memories”可知，选项B的确正确。,2. Which of the following is NOT true of a hoatzin? A. It cannot fly when it has claws. B. It eats green leaves. C. It has claws on its beak. D. It has the stomach of a cow. C 根据本文可知C选项 中has claws on its beak(鸟的嘴)与文中的has claws on its wings不符。,C,3. When camping , youd better avoid all the following EXCEPT_. A. standing dead trees around B. animal runs and caves C. homes of biting insects or damaging plants D. an area where people have obviously camped before,D,D 由文章第三段所述, 寻找宿营地时应避免直立的枯树、动物经过的路线或洞穴以及叮咬昆虫的栖息之地, 而尽量使用人们以前宿营时使用过的地方, 所以D项正确。,4. Which of the following is NOT true according to the passage? A. Spam is troubling for individuals and companies. B. Whoever spams should be sent to prison. C. Spam results in a loss of productivity. D. Computer problems increase production costs of companies.,B,B 因选项B与最后一段第二句Spammers should be fined, and perhaps sent to prison不符，言之过重了。此外，选项A与第二段第一句This problem is troubling for individuals and companies as well相符；选项C与第二段中的Such a situation results in a loss of productivity 相符；选项D与These computer problems raise production costs of companies相符。与选项相关的信息分布在两个段落里。,
