Answer 1

22. It was not until midnight__A__ the snow-capped peak.
A. that they sighted B. that they did not sight
C. did they sight D. had they sighted
这是一个强调句。it was……that……所以that不能省
原句为they did not sight the show capped peak until midnight

23. We could _B___ him with a detached house when he came, but he had specifically asked for a small flat.
A. provide B. have provided
C. not provide D. not have provided
could have done sth本可以做某事
"他来的时候我们本可以为他提供独立的大住宅，但是他却明确地提出要一件小的公寓”

24. This missile is designed so that once__A___ nothing can be done to retrieve it.
A. fired B. being fired
C. they fired D. having fired
missle与fire是被动关系，所以用过去分词。一般这种情况，once后面接动词过去分词的话，则不用加being，比较常见，记住就行，以后再选就知道了

26. Agriculture is the country’s chief source of wealth, wheat __D_ by far the biggest cereal crop.
A. is B. been C. be D. being
该句没有连词，即只能有一个谓语，前面的is即是整个句子的谓语，所以空里不能填谓语，即排除A.C，后面的部分如果是有连词的话应是这样wheat is by far the biggest cereal crop.因为不能有谓语所以用being表状态，been一般不单独用，与have、has一起

27. The opening ceremony is a great occasion. It is essential ___A_ for that.
A. for us to be prepared B. that we are prepared
C. of us to be prepared D. our being prepared
it is +adj+for sb+to do sth

28. He spoilt the poem by reading it in a ___B__ voice.
A. soft B. monotonous C. cheerful D. faint
spoilt是spoil的过去式，即毁坏，即他毁坏了这首诗，应填的是贬义词。
monotonous单调的，无抑扬顿挫的

31. She is one the most __A__ people in the company, for she is very influential.
A. vital B. special C. precious D. practical
因为她在公司里是十分有影响力的，所以应是重要的

37. If you have really been studying English for so long, it’s about time you __B___ able to write letters in English.
A. should B. were C. must be D. are
it is （high、about）time+that虚拟从句，固定用法，要记住的

40. This famous businessman__B__ most of the profits from his business to various charities after his success.
A. discharged B. donated C. designated D. distributed
为什么不用 distributed to？
这体现的是捐赠的意思，用donate比较好

Answer 2

其实，就语法来看是没错的。但是你要看他后面跟的是charity。也就是慈善机构。向慈善机构捐钱。他不是一种分配也不是投资。而是白给啊。如果后面是子公司或者是部门什么的可以用distribute，因为那是一种资金分配啊。
