If you go to Xi’an,you’ll find the palaces there more magnificent than commonly (supposing/supposed)这里我选的supposing,我觉得more后面的都是修饰前面find的,应该是主动,答案上是后者,

I’ll be away on a business trip.Would you mind looking after my cat?--- Not at all.(I’d like it/I’d be happy to)我决定的额前面用would问了,后面用would也没错啊,
( If he were to study / Had he studied hard) he would have passed the exam.
No sooner ( did they hear the news than /had they heard the news than) they rushed out into the street.
He was unable to make such progress,(A.hard as he tried/as hard he tried).

1、If you go to Xi’an,you’ll find the palaces there more magnificent than commonly (supposing/supposed) 这里我选的supposing,我觉得more后面的都是修饰前面find的,应该是主动,答案上是后者,我不明白哪里错.
　　【解析】
　　首先,more后面的不是修饰前面的动词find,而是 find 后宾语the palaces 的补足语,意思是“发现这些宫殿更加壮观”； than 后的 commonly 是there 的比较对象,即“那里的宫殿比普通的宫殿更加宏伟”.
　　你可能指用supposing/supposed 替换 if 表示条件.Supposing 和supposed 都可以引导条件状语从句,但是需要考虑与主句主语的逻辑关系.本句的主语是 you,主要考虑的是它们与 you 的逻辑关系,即究竟是 you 本人supposing 去西安,还是 you 被人supposed 去西安.Suppose 的不同形式所表示的意思是有区别的.
　　Supposing you go to Xi’an = If you suppose that you go to Xi’an（如果你假定自己要去西安）
　　Supposed you go to Xi’an = If you are supposed that you go to Xi’an （如果有人假定你要去西安）
　　很显然,应该是后者.
　　2、Do you mind my taking this seat?----(Yes,sit down please /.B.No,of course not)这里前后选项在口语里貌似都出现过,我选后者哪里不妥吗?
　　【解析】
　　Do you mind 是针对介意还是不介意而向对方征求意见的.如果用 yes 回答,意思是“我是介意的”,等于 Yes,I do的省略,接下来再说sit down please 势必前后矛盾.如果用 no,则是“我不介意”,等于No,of course I do not mind.因此,用后者回答才是正确的.
　　3、I’ll be away on a business trip.Would you mind looking after my cat?--- Not at all.(I’d like it/I’d be happy to)我决定的额前面用would问了,后面用would也没错啊,答案是后者
　　【解析】
　　’d like（=would like）后面只能跟不定式表示“乐于/愿意做某事”,不能直接跟名词或代词 it,因此用I’d like it是错误的.Would be happy to 和 would like to 的意思差不多.,
　　4、( If he were to study / Had he studied hard) he would have passed the exam.
　　【选择】Had he studied hard
　　【解析】
　　后面的would have passed是对过去的虚拟,只能选择过去完成时Had he studied hard 表示过去的虚拟条件.If he were to study 是对将来的虚拟,前后时态不一致.这句话的意思是“如果你早在这以前就用功学习,那么你那个时候你考试就能及格”.
　　5、No sooner ( did they hear the news than /had they heard the news than) they rushed out into the street.
　　【选择】did they hear the news than
　　【解析】
　　“No sooner（比较级）+ than从句”表示“一如何就如何”,而had they heard the news 本身是虚拟条件状语从句,等于 if they had heard the news,后面再跟比较从句 than 就成了缺少主句的两个状语从句.
　　6、He was unable to make such progress,(A.hard as he tried/as hard he tried).
　　【选择】hard as he tried
　　【解析】
　　hard as he tried 等于 although as he tried hard.用 as 引导让步状语从句时,必须要把副词、形容词或名词放在句首.另如：
　　Ridiculous as it seems,the tale is true.尽管这个故事看似荒唐,但它却是真的.
　　Child as he is,he can do it better.虽然是个孩子,他却能把这件事做得更好.
　　7、We will work (whenever/wherever) we are needed.
　　【解析】
　　用哪一个语法上都没有错误,但是在情理上来说应该用wherever.
　　whenever = at whatever time,We will work at whatever time (when) we are needed【什么时候需要,我们就在什么时候工作（我们会在需要我们的任何时间工作）】
　　wherever = at whatever place,We will work at whatever place (where) we are needed 【哪里需要我们就在哪里工作（我们会在需要我们的任何地方工作）】
　　8、(Though/As) still half drunk,he made his way home.
　　【选择】Though
　　【解析】
　　Though still half drunk 等于Though he was still half drunk 的省略,用as 参见第6题的解释.
　　9、(Although/In spite of) she was very tired,she went on working.
　　【选择】Although
　　【解析】
　　Although 是连词,后面跟句子.In spite of 是复合介词,后面跟名词或动名词.正确说法有两种：
　　Although she was very tired,she went on working.
　　In spite of being very tired,she went on working.
