Question

呃、问几道英语单项选择题。拜托了。

RT、呵呵。我就把我错选的和正解放上来了。各位帮帮我、给我解释下为什么错了。谢谢。

1.She was not___________his presence until he was quite near her.
C.concerned with D.aware of 正解

4._________decision you make,you parents will always support you.
A.Whichever B.whatever 正解

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 正解 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。

Answer 1

1. 翻译：直到他很靠近她，她才知道他也在场。
解释：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。
解释：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）。
解释：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。
解释：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...

Answer 2

concern with是‘关心’aware with是‘意识到’，根据题干显然选后者。记住，whichever必须用在有选择的时候，‘无论选择哪一个desion’，但题中并没提出可供选择的desion。倒数第二题考词汇，最后一题是语法，表示‘一定不是他’。可以理解了吗？
