ever可用在现在完成时 否定句中　表示强调not　　ever＝never
8 To save the drowning child, the boy plunged into the icy water without hesitation,____ his own safety．
怀疑答案有误A. despite of B. as to
应该是 regardless of
9 ______,he never forces his ideas on others.
B.Experienced as he is这是让步状语从句
10 however ,I did manage to save myself from a beating by telling my mother I had only one good hairbrush as she'd broken ____other ones in the beating.
B.other 前加the。此处表特指，故应用the other 修饰
11The year of 2008 ___ the success of the summer olympics in China.
B　　saw见证了
12 He said I didn't try my best.That's ___ I disagreed with him.
B.where连接副词引导表语从句　并在从句中作状语
选项A是代词，从句中结构完整　　无需代词　故错

1. A,不能去的理由就是因为“。。。情况已经出现了” 2. B发生在arrive之前的过去动作。 3. A.沙发的干净状态是clean动作造成的结果 4. Beither表示两者中的任何一个都可以。 5. B It won' be long =soon, It won't be long before 是个常用句型，”不久以后就。。。“不久就回复正常了 6. B 表示独一无二的职位名称作表语，宾语，宾补时，其前部加冠词 7. B with可以表示在什么单位工作，有时也用on, has ever done表示曾经的意思 8. A despite of =without considering his own safety 的意思 9. B. as 引导让步状语从句时意思等于Although/though,但是常用倒装语序。 10. B 相当于 That's the point on which I disagreed with him. 再比如类似例子：Put thebook where it was.

选d。表示目的，用动词不定式。
