2014年成人英语三级考试语法试题复习：非谓语动词(17)

　　1. Arriving at the bus stop, ____ waiting there.

　　A. he found a lot of people B. a lot of people were

　　C. he found a lot of people’s D. people were found

　　【答案】A 主句arriving at the bus stop 省略了when he was, 而waiting there的主语是people.所以状语的逻辑主语应该和句子的主语保持一致,故排除B, D.在发现某人做某事时应用名词或代词的宾格,不可以用所有格形式，故C项可以排除,正确答案选A.句意是“当他到达车站时,发现有很多人等在那里.”

　　2. To succeed in a scientific experiment, ____.

　　one needs being patient person

　　patience is to need

　　one needs to be patient

　　patience is what needed

　　【答案】C. 本题考查的是独立主格中分句和主句的主语要一致。逗号前面是非谓语做状语，逗号后面需是句子，且非谓语的逻辑主语应与句子主语一致，排除B、D。要想在科学实验中取得成功，必须要有耐心。

　　Need的用法：

　　1. 作情态动词时，与其他情态动词“can”，“may”，“must”的用法基本相同。

　　2. 作实义动词时，人+need+to do;物+need+doing=物+need+to be done。

　　3. 另外，“need”后还可以直接跟名词。

　　3. Having taken our seats, _____.

　　A. the professor began the lecture B. the lecture began in no time

　　C. we were attracted by the lecturer immediately D. the bell announced the beginning of the lecture

　　【答案】C。本题考查的是现在分词作状语。前半句话是分词形式的非谓语，所以后半句话应该不缺成分，有主语和谓语，而且句子主语也要是非谓语的逻辑主语。而Having taken our seats显然是我们才能发出的动作，因此选择C。我们都坐下以后，立刻被讲座吸引了。

　　4. Unless ________ to speak, you should remain silent at the conference.

　　A. invited B. inviting C. being invited D. having invited

　　【答案】A。被邀请。

　　5. ________ where to go, the old man turned to a policeman for help.

　　A. Lost his way and not knowing B. Lost his way and didn't know

　　C. Losing his way and didn't know D. Having lost his way and not knowing

　　【答案】D。迷了路又不知道去哪里，老人向警察求救。非谓语作状语，发生在谓语动词之前，所以用非谓语的完成时态，因此选择D。
