The meeting to be held tomorrow is very important. 1) 带to的不定式作宾补。很多动词如: allow, order, force, permit, tell, want, wish, forbid, advise, persuade, warn等后面作宾补的不定式都带to。 如: He didn’t allow us to smoke in his house. 他不允许我们在他的家里吸烟。 2) 不带to的不定式作宾补。使役动词make, have, let;感官动词see, watch, observe, hear, listen to, notice等后面作宾补的不定式不带to。 如: He made a face and made everybody laugh. 他做了一个鬼脸, 逗得大家都笑了。 如果上述结构变为被动语态,不定式就由原来的宾语补足语变为主语补足语,此时第2类动词(let, have无被动语态)后原来不带to的不定式要加to。 如:I saw him go upstairs. He was seen to go upstairs. 有人看见他上楼去了。 Translation 1. I forgot to ask you to go to the community service centre. 2. It is very important to turn off the electricity before you check the machine. 3.
