A．be blamed for B．be blamed on

C．blame for D．blame on

答案 C [blame意为“责备，谴责”，to blame作表语时常用主动形式表被动意义，介词for表示原因。blame常构成的结构为：blame sb for sth/doing sth“由于(做)某事而责备某人”；blame sth on/upon sb“将某事怪罪到某人头上”；sb be to blame (for sth/doing sth)“某人由于(做)某事而应受责备”。 ]

7．The boy sat there sad，________by his friends.

8．—Thank goodness.It is much warmer today than yesterday.

—Yes，I________my coat today.

A．couldn't have worn B．wouldn't have worn

C．needn't have worn D．mustn't have worn

答案 C [考查情态动词。句意：“谢天谢地。今天比昨天暖和多了。”“是的，我今天本不必穿外套的。”couldn't have done sth“不可能做了某事”，wouldn't have done sth常用于虚拟语气；needn't have done sth“本没有必要做某事”；没有mustn't have done sth这种结构。]

9．At that moment，I was just standing by the window in my room，________ I could see what was occurring on the street.

A．from which B．from whose

C．from that D．from where

答案 D [考查定语从句。句意：那时，我恰好站在我的房间的窗边，从那里可以看到大街上正在发生的事。定语从句中的地点指by the window，而不是the window，因此是“从窗户处”而不是“在窗户”，故选from where。]

10．—Did you go to the party last night?

—Yes.But I'd rather________.It was so ________.

A．not go；tiresome B．not have gone；exciting

C．not have gone；tiring D．go；interesting

答案 C [答句句意：——是的，我去了，但是我宁愿没有参加，因为聚会很枯燥。would rather not have done意为“宁愿不做 (而实际做了 )”，这是一种虚拟语气的用法。根据句意可知选C。B项不符合逻辑。]
