七年级英语语法精讲：有关非谓语动词的重要考点

　　原则上说，动词用作主语，只能是不定式或动名词，不能是分词形式。这类考题命题还往往用动词原形作为干扰项进行考查，同学们做题需引起注意。如：

　　It’s necessary to be prepared for a job interview; _________the answers ready will be of great help. (北京卷)

　　A. To have had B. Having had C. Have D. Having

　　【分析】答案选D。动名词短语用作主语。

　　十、考查“(be +) 过去分词+介词”结构

　　有一类“be+过去分词+介词”结构，如be interested in, be worried about, be lost in, be dressed in 等，也往往是命题的热点。如：

　　1. _________ in the mountains for a week, the two students were finally saved by the local police. (江苏卷)

　　A. Having lost B. Lost C. Being lost D. Losing

　　【分析】答案选 B。因表示“迷路于”是lose oneself in，题中没有oneself, 所以the two students与lose是被动关系，应该用过去分词作状语。

　　2. _________ in a white uniform, he looks more like a cook than a doctor. (湖南卷)

　　A. Dressed B. To dress C. Dressing D. Having dressed

　　【分析】答案选 A。由dress的宾语一定是人或oneself可知，dress与he是动宾关系，即he与dress是被动关系，要用过去分词作状语，Dressed in …=As he is dressed in …

　　十一、非谓语动词的综合考查

　　有时命题者会将多个知识点综合起来进行考查，如在考查被动式的同时兼考完成式，在考查不定式的同时兼考分词，等等。如：

　　1. I don’t want _________ like I’m speaking ill of anybody, but the manager’s plan is unfair. (天津卷)

　　A. to sound B. to be sounded C. sounding D. to have sounded

　　【分析】答案选 A。表示“想要做某事”want后只能接to do，排除选项C;sound like中sound是系动词，属不及物动词，不能用于被动语态，排除选项B;sound 发生在want后，故不用完成式，排除选项D。

　　2. “Is Bob still performing?” “I’m afraid not. He is said _________ the stage already as he has become an official.” (江苏卷)

　　A. to have left B. to leave C. to have been left D. to be left

　　【分析】答案选 A。因he与leave是主动关系，不用被动式，排除选项C和D;由already可知，要用完成式。
