　　参考答案与解析：

　　1. B。take带走(去)；bring带来。另外，主语Jim与动词take之间构成逻辑上的动宾关系。

　　2. D。考查固定句型“Why not do ...?”。

　　3. C。不定式所表示的动作在谓语动词所表示的动作之前发生，故应使用不定式的完成式。

　　4. A。不定式作定语时，既可以与其所修饰的名词或代词构成逻辑上的主谓关系，也可以与其所修饰的名词或代词构成逻辑上的动宾关系。当不定式的逻辑主语是句子的主语或谓语动词的宾语时，不定式应使用主动形式。

　　5. C。与不定式连用，并且要表达“是否”之意时，只能用whether，不能用if。

　　6. D。动词不定式作tell, show, know, decide, learn, teach, discuss等动词的宾语时，不定式前面可以带疑问代词、疑问副词或连词whether等，即：who, whom, what, which, when, where, why, how, whether等 + to do。

　　7. C。不定式作目的状语。

　　8. D。当不及物动词的不定式形式作定语，且该不定式与其所修饰的名词或代词构成逻辑上的动宾关系时，其后需使用必要的介词。例如：a river to swim in, a person to laugh at, nothing to worry about, a chair to sit in, a hotel to stay at, a pen to write with等等。

　　9. A。不定式的逻辑主语既可以用for sb.也可以用of sb.来表示。当形容词强调人的品质、特点时，要用of sb.。常见的这类形容词有：kind, nice, good, bad, polite, rude, wrong, right, clever, careless等。

　　10. C。but用作介词时，后面可接带to或不带to的不定式。除了短语can't help but do, can't choose but do, do … but do …之外，介词but后常跟带to的不定式。have no choice but to... 表示“除了……之外毫无选择；只好……”

　　11. D。考查不定式作目的状语。

　　12. B。so as to do或in order to do在句中作目的状语，其否定形式为so as not to do和in order not to do。

　　13. C。动词need后面的动词作其宾语，且与need的主语构成逻辑上的动宾关系时，need后面的动词可用doing或to be done两种形式。

　　14. A。动词不定式跟在某一形容词后作状语，且这个形容词用来说明主语的性质、品质、特征等时，不定式通常使用一般式，而不使用被动式。再如：

　　The box is too heavy to carry.

　　He finds English difficult to learn.

　　15. B。考查不定式作表语。“be+不定式”可用来表示将来。take an exam参加考试。
