Question

大家好!请教两道题!
You may go to play football as soon as your homework _______(finish).
Middle school students ________ (tell) not to smoke.
We ________(watch) the boys _____ (play) games on the playground when something strange happened.

Answer 1

1.is finished 因为在时间状语从句和条件状语从句中,用一般现在时代替将来时.
2.are told 中学生被告知不要吸烟.
be told not to do sth 是tell sb not to do sth的被动语态.
3. were watching , playing
这是固定句型：was/were doing...when... 意思是“正在做某事,就在此时.”
这个句型要关键看第一个分句的时态,还可以说be about to do when...正要干某事就在此时...
第二个空：watch sb doing sth 看见某人在干某事 doing sth在句中作宾补.
watch sb do sth.看见某人做了某事, do sth 是不带to的不定式作宾补.
祝你学习愉快~
