回答不论先来后到，只按精彩度采纳答案~

1D． your letter , I would have started off two days ago. A.If I received
B.Should I receive C.If I could have received D.Had I received
(显然这是虚拟语气的Should，Had和Were的倒装，为什么用Were不用Should呢，是不这三个在时态上有什么差别啊)

2C By no means his plan to practise English . A.he has given up
B.up he has given C.has he given up D.he did give up
（为什么不是does he havegiven up，非完全倒装到底是前置什么样的词呢）

3A.—You seem to have known all about the accident .— .
A.So I have B.So I do C.So have I D.So do I
(为什么不选B)

4B22.—It was careless of you to have left your clothes outside all night .
—My god! . A.So did I B.So I did C.So were you D.So did she
(假设有So I was，为什么不选So I was呢，诸如此类，到底该根据哪个词…)

5D27.—I’ve left my pen at home .-- . Use mine.
A.Here are you B.Here it is C.Here is it D.Here you are
(Here you are感觉是好熟悉的一个词，但是根据副词后跟代词谓语动词不提前，难道are是谓语动词？原谅我基本知识不扎实啊)


6C. and caught the mouse . A.up the cat jumped
B.the cat up jumped C.up jumped the cat D.jumped up the cat
(没见过的知识，讲一下~)

7C36.Not once him to . A.he has done as I asked B.he has done like I ask
C.has he done as I asked D.has he done like I asked
(D为什么不行…隐约记得学过一个与as相似的like)

8A60.To all the people here the honor for the success.
A.belongs B. belongs to C.is belonged D. belong to
(虽然做对了可是这种倒装没讲过，简单讲讲吧)

1.应该是选D啊 完整的应该是If I have received...就是对过去的虚拟，这是if的省略，倒装句Had提前。
2.C 不完全倒装就是把助动词提前，现在完成时的助动词就是have
3.A 完成时have done的助动词是have嘛
4.B 同上
5.D here，there，away，on等方位介词放句首，名倒代不倒（主语是名词就倒装，是代词不倒装，如，Here comes the bus.就不倒装的）
6.A 解释同上
7.C like是介词，as是连词，所以as可以连接一个句子，后面I asked有主语和谓语构成了主谓结构的句子，所以不能用D
8.这个我倒没看懂了，空格在哦哪儿呀？我就知道belong to是没有被动和进行时的

想补充一下2-4题吧，需要助动词提前倒装时，要先弄清楚助动词是怎么样的吧：
一般现在时--do/does/is/am/are
一般过去时——did/was/were
一般将来时——will
现在完成时——have/has
过去完成时——had
将来完成时——will have
现在进行时——is/am/are
过去进行时——was/were

好久没做这方面的语法联系了，说不完善见谅哈！
