呃、问几道英语单项选择题.
RT、呵呵.我就把我错选的和正解放上来了.
1.She was not___________his presence until he was quite near her.
C.concerned with D.aware of
4._________decision you make,you parents will always support you.
A.Whichever B.whatever
9.People throughout the world are facing a serious water problem at present.The related department is _________to everyone to save water.
正解：appealing
12.-I saw a girl that looked very much like Nancy in the bookstore just now.
-It________her.She has just gone to America.
B.couldn't have been D.mustn't have been
我觉得must也可以用来对过去的推测啊。
第9题把sppealing填进去是什么意思啊。呼吁么。

答案

1.翻译：直到他很靠近她,她才知道他也在场.
be concerned with 和...有关联 ；be aware of 知道
4.翻译：不管你做出什么决定,你的父母亲总会支持你的.
whichever=no matter which；whatever=no matter what
用which必须是上下文给出选择的范围,而如果只是泛指“什么”,则用what即可.
9.翻译：全世界的人们现在都面临着严重的水(短缺)问题.相关部门正在呼吁/恳请每个人都要节省水（资源）.
appeal to sb to do sth 恳请/呼吁某人做某事
10.翻译：--刚才我在书店看到了一个长得非常像Nancy的女孩子.
--不可能是她.她刚刚到美国去了.
must have ...一定做过某事；can't/couldn't have...不可能做过某事(以上是对过去发生的事情做的肯定或否定的推测).
没有mustn't have...的短语,must have...的否定形式就是can't/couldn't have...
