1.__i accept the gift or refuse it is none of your business.填whether还是no matter when?好像填whether翻译别扭...
-------答：whether,这里是whether...or..：不管我接受还是拒绝这个礼物，都不关你事。

2.it is strange __.填that no one liked this book还是that no one should like this book.为什么 ?
-------答：it is strange that 后面一般用虚拟should + 动词原形，should可省略。

3.____nothing to do with us .填what he has done is 还是what he has done has.还是?
-------答:have nothing to do with 与。。。无关

4.i have no idea _what_ the word "infinity" means.什么从句?为什么填以下内容不行?1.what does the word infinity mean 2.what the meaning of the word infinity was 3.what was the meaning of the word infinity.
--------答：宾语从句。i have no idea= i don't know 。既然是从句，就正常语序，1.不行 2.was换is 3.was 换is。但都没原句好。

5.she looked _as though_ she were ten years younger.为什么不填THAT,怎么翻译?为什么是AS THOUGH?
------答：as if /as though 意思是：好像。 而且look经常和as if/though连用，意思：看上去好像。而且look不能接“that”从句。

6.that's _what_ the party called on us to do.为什么填WHAT?怎么翻译?
------答：what引导的表语从句，what在从句里作do的宾语。翻译：那就是党要求我们去做的事情。

7.is was _because_ he worked hard that he succeeded.为什么不能填since和for.
------答：强调句，since for的语气太弱，不适合强调句。

8.his suggestion _that_ we go to see the art exhibition interested every one of us什么从句?
------答：同位语从句。从句就是suggestion的内容。

9.are you sure _she is honest_?为什么不填whether she is honest.?什么从句
------答：宾语从句。作形容词宾语。are you sure she is honest? 意思是：你确定她是诚实的吗？--如果你用whether，岂不是就成了:你确定她是否是诚实的吗？--哪有这样问话的?

10.he was interested in _all that_ he had seen at the exhibition.虽然all that =what,但是为什么不填WHICH?WHICH也可以做成分啊...?
--------答：先行词为不定代词时，比如all，必须用that，不能用which.

11.he often thinks of _how_ he can do more for the four modernizations.为什么不填WHAT?
--------答：从句里已经有了宾语more，不缺宾语，不用what.

12.is this _where_ we met each other two years ago?什么从句?还原为简单句怎么做?
--------答：表语从句。这个句子还需要用还原法来理解么？“这就是我们2年前会面的地方”
