　　一、 重要干扰项

　　重要干扰项就是指，这种选项虽然不是正确答案，却与原文不冲突(或者很难判断是否与原文冲突)，它们与正确答案看起来比较相似，只不过不如正确答案更准确、更完整或更严谨。我们和小编一起来看下面的例子：

　　In Tarkovsky’s opinion, the attraction of the cinema is that it

　　A aims to impress its audience.

　　B tells stories better than books.

　　C illustrates the passing of time.

　　D describes familiar events.

　　我们可以定位到原文的C段和D段，C段提到：The frightened audience could not accept that they were watching a mere picture. Pictures were still, only reality moved; this must, therefore, be reality. In their confusion, they feared that a real train was about to crush them. 这一段文字表达了观众当时的反应，观众们很难接受自己看到的是图画而不是事实。D段提到：The key to that magic was the way in which cinema created a dynamic image of the real flow of events. A still picture could only imply the existence of time, while time in a novel passed at the whim of the reader. But in cinema, the real, objective flow of time was captured. 这段文字描述了电影创造了事件随时间的发展演变，并且用picture和novel进行类比，强调电影的魔力是让人清楚地看到事情流畅地随时间演变。

　　根据这两段文字所表达的意思，很多学生会选择A或B选项，因为原文提及了观众、小说(书)的内容。A和B两个选项与原文所讲的内容并不是矛盾或完全不符合的。因此，这两个选项就干扰了我们正确的选择。当我们把这两段文字仔细推敲之后，发现描述观众的反应和对比书和电影的区别，都是为了表达电影的魔力在于表达事件随时间的发展这一主题含义。C项的含义比AB要更准确，因此答案选择C项。

　　二、 错误干扰项

　　相比之下，多选题目的错误干扰项就较容易识别出来了。我们可以看到，有些题目中，某个选项与原文是直接矛盾的，那么肯定不会选择它为正确的答案。比如：

　　A recent survey found that in British secondary schools,

　　A there was more bullying than had previously been the case.

　　B there was less bullying than in primary schools.

　　C cases of persistent bullying were very common.

　　D indirect forms of bullying were particularly difficult to deal with.

　　我们看到原文，其中有一句话是：There was less bullying in secondary schools, with about one in twenty-five suffering persistent bullying. 通过这句话，我们可以明显地判断出，C项的含义与原文是矛盾的。very common和one in twenty-five的比例是明显不符的。因此，C选项就是一个错误的干扰项，我们可以确定地排除答案是C项的可能性。
