何时跟to说bye-bye
动词不定式的基本形式是“to 动词原形”,本身没有人称和数的变化,在句中不能作谓语,其否定形式为在不定式符号to前加not。可是,我们有时候会见到动词不定式前边的to何时被省略的情况,这是怎么回事呢?先请看以下两个例句:
① We often hear the boy read English here.
在以上两个例句中,动词不定式前的to就被省略了。一般来说,省略不定式符号to 常见于以下情况:
1. 作宾补,一感二听三让四看半帮助
宾补,也就是宾语补足语,在句中对宾语补充说明。动词tall(让)ask(请求)teach(教)wish(希望)等常接动词不定式做宾补。
如:Dad wishes me to pass the exam.
但以下这些动词后常接省略了to的动词不定式作宾补:即一感feel;二听listen to/ hear; 三让make/ let/ have; 四看see/ watch/ look at/ notice;半帮助help sb (not ) do sth.
如:I felt someone come in just now. 我刚才感到有人进来了。
<特别注意>here/ see/ make sb do sth. 用在被动语态中,常把to还原。
如:We made him do it.= He was made to do it by us.
我们让他做这件事。/ 他被我们要求做这件事。
2. 记句型,牢记心中定成功
① You'd better ( not ) do sth. 你最好(不要)做某事
如:You'd better not leave me alone.你最好别把我一个人单独留下。
② Will/ would you please ( not ) do sth? 请(不要)…,好吗?
③ prefer to do A rather than do B 与做B相比,更喜欢做A(宁愿做A,也不愿做B)
她小时候宁愿待在家,也不愿出去。
