英语不带to的不定式详解....！！！

Answer 1

英语不带to的不定式：
1. 使役动词 let,have,make 等后接不定式作宾语补语时, 作宾语补语的不定式不带to。如：Let me sit down! 让我坐下!(不能用: to sit down)。再如: His mother often makes him do housework. 他妈妈经常让他做家务事。(不能用: to do housework)。
2. 感官动词 see, notice, watch, look at, hear, listen to, feel 等后作宾语补语的不定式不带to。如：He saw the man walk into the room. 他看见这个人走进了房间。(不能用: to walk into the room) 。
但是应该注意的是：如果上述句子变成被动语态的句子，就一定要加上 to，例如：His mother often makes him do housework. 他妈妈经常让他做家务事，如果变成被动句，就是：He is often made to do housework (by his mother). 再如: He saw the man walk into the room. 他看见这个人走进了房间, 如果变成被动句，就是：The man was seen to walk into the room (by him). (当然这2句被动语态句子括号中的: by his mother 及by him 都可以省略，因为被动语态不强调动作的执行者，但是: to do housework 及 to walk into the room 中的 to 却千万不能省略)。
