注：英语选择题的答案都已经给出了,能几题就几题啦~当然,若能全部解答出那就太好了~
再注：所说的解答不是选出这道题选A or B or C or D这样的，而是说想知道为什么要这样做^ ^

不考虑我的采纳率,给你进一言：
一贴一题一问.
要有自己的疑问,至少要说出你自己做错的那一项（另两项就不用费口舌去解释了,因为你已经将它们排除了）
看了所有题目,发现答案没有给错的.有两题值得我讲解一下：
9.__B__ that Mary leave it to him to repair the washing machine.
A.It is said B.It is suggested C.It is hoped D.It's thought
答：从形式上看,到that为止,这四个选项都是可能的.从句意看,这四个都可以,为什么选B,而不选其它三个呢?
关键在于这个that引导的（真正的）主语从句中的谓语leave =should leave 省略了should
原来本题句实为考查虚拟语气和真实语气的.这四个动词中,只有suggest 是虚拟十动词之一,与它对应的宾语从句、同位语从句、主语从句、表语从句中的谓语动词要用should +V,should 常省略（主语常为第三人称单数）
12.The mother seldom let an opportunity to help her son make up for the hours of schooling he had missed __C__.
A.to pass B.passing C.pass D.being passed
