问题: 几道单选题????

1 Teaching is hard work:I love it,_____
A though B yet
为什么选A 不选B

2 —Guess what?I drove my new car at a speed of 100km/h this afternoon . It was fun.
--Were you crazy?You _____yourself!
A can kill B might kill C would have killed D could have killed

答案选D 可为什么不选B 即使选D也要把could改为might“可能”才对啊

How come you stepped into the lab with your shoes on?Youre _____ to take them off before you enter it.I told you so!
A expected B supposed C forbidden D permitted
为什么答案选B C不对吗?我觉得B没有不允许的意思啊!

解答:

1.though “即使” 应放在前面之前理解 Though teaching is hard work

2.虚拟语气 ,事情并没有发生,而且是过去世态,所以后面用woule have done

3.,把鞋脱下来,才被允许进入,这个permitted应该+to enter it而不是
象你说的那样,被允许脱鞋。
supposed
在这里的意思是“必须的”
He is supposed to go to the store.
她必需去商店
forbidden 是禁止的,句子这么改就通顺了,you are forbidden to enter the room before you take them off.
