如何做判断是非的题目

是非题也称之为正误判断题，因为问的是选项中对文章中的事实的转述是否真实，提法是否正确，文章或作者是否提及。例如：

Which of the following statements is (not) true?

Which of the following is (not) mentioned in the passage?

Which of the following does not explain _______ ?

All of the following are true except ________.

可见这些问题的四个选项要么是"一正三误"，即一项是对的，是符合文章事实的，其余三项均是错的;要么是"一误三正"，即一项是错的，是不合原文事实的，其余三项均是正确的。

解答这类问题，头脑应当清楚：问题是要求把正确的选项圈出，还是要求把错误的选项圈出。有的考生不看清问题，就去选择选项，想当然地把正确的，符合文章事实的一项圈出，而问题明明问的是Which of the following is not true (mentioned)，结果误选。
