几句when,as soon as语法上的句子
1）As soon as they enter the garden ,they ____ by a smiling young lady.
A.are greeted B.were greeted C.are greeting
答：A
译：他们一进入花园,就会受到一个年轻女子的笑脸相印.
析：如果楼主从句中的谓语动词enter没有打错（确实是enter而非entered)的话,则表示的是一个经常发生的事情,每次只要一进入这个花园,都会发生的事情,所以主句用一般现在时（的被动语态）.如果从句中的为entered,则说的是过去的事情,则选B.
2）He never goes home until he _____ all his homework.
A.finished B.has finshed C.is finished
答：这句话中的主句是一般现在时态,表示的是经常发生的情况.until引导的是时间状语从句,用现在时态表示现在（或将来）排除A（这时讲过去的事情的,如：He didn't go home until he (had) finished all his homework.讲的是那一天,他一直等到所有的作业都（已经）做完了,才回家去）.他做完做业是主动的,排除被动的C.如有一个D.finishes也是可以的.
译：他（经常）要等到完成了所有的作业之后才回家.
我知道答案是AB,但不知道理由,只知道until前后时态一致什么的,帮忙解释一下,基础一点,当我是白痴把,
答：你别想复杂了,也没有什么until前后时态一致的什么的.你也不是白痴.如你是白痴,咱就是傻子了.
反正不要语法错就行啦！谢谢哦 1. Protection of the bad environment is everyone's responsibility, we should start small, from now on. 2. I
一个A， 后一个B
1) as soon as 引导的时间状语从句，一般现在时的被动语态。
2）not until 引导的时间状语从句，逐句是一般现在时，从句要保持一致，用跟现在有关系的时态，现在完成时包含现在时。
