\x05 省略to的不定式\x05\x05除了我们所熟知的使役动词make、let、have和感官动词see、watch、notice、hear、feel、listen to、look at、observe等后通常用省略to的不定式作宾语补足语外,还有如下结论 \x05在had better、would rather、may/might as well、rather than等搭配之后,动词不定式也不带to。例如：If you'd rather be aloue,we'll all leave here。如果你宁愿独自呆着,那我们都离开这儿。You might as well go without her。你们还是不带她去为好。\x05在介词but,except之后,如果其前有动词do的某种形式,其后不定式一般不带to,反之则必须带to,表示“不得不,只能”。例如：He does nothing but watch TV all day long。他整天除了看电视无所事事。I have no choice but to accept the fact。我别无选择只有接受这个事实。\x05以why或why not开头引起的无主语中,动词不定式要省略to。Why argue with him?为什么要和他争辩呢?Why not tell me about it in time?为什么不及时告诉我这个问题?\x05在主语以what、all、the only thing等开头的包含行为动词do的句子中,作为表语的不定式常可省略to。The only thing you can do is wait and see。你唯一可做的只有等待和观望了。All I can do is help you finish the work on time。我能做的所有事情就是帮你按时完成工作 \x05为了避免重复,由and或or连接两个不定式时,一般可以省略第二个不定式符号to。例如：I'm really puzzled what to think or say。我真不知道该怎么想和怎么说。We want to swim and climb the hills next Saturday。我们下个星期六想游泳、爬山。注：如果前后两个不定式在意义上有对比关系时,不定式符号to不能省略。例如：I came not to scold,but to praise you。我来不是批评你,而是表扬你的。\x05一些含有but的固定搭配短语如can not help but、can not choose but、can not but、can but等结构中,but后面跟不带to的动词不定式。例如：It rained hard,so they couldn't choose but stay at home。雨下得很大,他们只得待在家里。The old lady could but walk slowly with a stick。那个老太太只能拄着拐杖慢慢地朝前走。\x05在动词help之后可用不带to的不定式,也可用带to的不定式。例如：Will you help me(to) carry the bag?你能帮我拿这个包吗?
