典型高考英语陷阱题详解·情态动词

1. “Mike is often absent from class.” “Tell him he _________ answer for it if he goes on behaving like that.”

A. shall                        B. will                        C. would                        D. can

【陷阱】几个干扰项均有可能误选。

【分析】最佳答案选A。shall 用作情态动词主要有以下两个用法：

(1) 用于疑问句中征求意见。如：

Shall I help you? 要不要我帮帮你?

Shall I open the window? 要我把窗子打开吗？

(2) 用于陈述句中表示允诺、告诫、警告、威胁、命令、规定、必然性等(可用于各类人称)。如：

You shall suffer for this. 你会为此事吃苦头的。(表威胁)

Each competitor shall wear a number. 每个参赛者要戴一个号码。(表规定)

You shall hear everything as soon as you come. 你一来就可听到所有情况了。(表允诺)

请做以下试题(答案均选 shall)：

(1) “I promise that she _________ get a nice present on her birthday.” “Will it be a great surprise to her?”

A. should                        B. must                        C. would                        D. shall

2. You _________ pay too much attention to your reading skill, as it is so important.

A. cannot                     B. shouldn’t                  C. mustn’t                  D. needn’t

【陷阱】几个干扰项均有可能误选。

【分析】最佳答案选A。cannot…too…是英语中一个十分有用的表达，意为“不可能太……，无论怎样……也不算过分，越……越……”。如：

You can’t be too careful. 你越仔细越好。

You can’t praise the too much. 这本书值得大加赞扬。

We cannot work too much for the people. 我们为人民做工作是不可能做过头的。

A woman cannot have too many clothes. 女人买的衣服再多也不算多。

注：有时也可用 can never, impossible 等与too连用来表示类似意思。如：

It is impossible to get there too soon. 去那儿越早越好。

3. “Is John coming by train?” “He should, but he _________ not. He likes driving his car.”

A. must                        B. can                        C. need                        D. may

【陷阱】可能误选B或C。

【分析】最佳答案为D。may 表推测，may not 意为“可能不(会坐火车来)”。句中的 He should 为 He should come by train 之省略，由于其后出现转折连词 but，说明语意有变化，再结合下文的 He likes driving his car，便可决定此题选D。注意，不能选B，因为can表示推测时通常不用肯定陈述句。

4. “I heard they went skiing in the mountains last winter.” “It _________ true because there was little snow there.”

A. may not be                 B. won’t be                  C. couldn’t be               D. mustn’t be

【陷阱】几个干扰项均有可能误选。

【分析】此题最佳答案为C，主要由下文的 because there was little snow there 这一语境所决定，既然“没下什么雪”，那么“滑雪”就应是“不可能”，所以选 couldn’t be，即选C。
