说明理由并翻译
理由再具体一些，尤其是6、8题

Answer 1

1.选B,这是固定搭配：it's not until···that···,“直到··才·”
如果选D,则是：直到这个老工人来我们才不开始实验.
B的意思是：直到老工人来我们才开始实验.（两者相比,B更好）
2.选C.当not none等这些含否定意义的词放句首时,句子倒装（即把助动词do does、be动词、情态动词之类的提前到主语前面）,则C的意思是：他昨晚说了不止一个词
3.和第二题一样,句子倒装,选D
4.选D.动词放句首是只有doing和to do形式,to do表目的.D选项的意思是：当老师的那些日子让人看不起,C则是：去当老师的日子让人看不起
5.选D,指人用who 或whom,介词后面用whom
6.选D,主语是人,A B中的it不就是代表不是人嘛.在C,D中选,nobody就是否定,反义疑问句前面否定,后面用肯定
7.选D,前面的decided表示是过去时态,在B D中选,B中的what i did表示我已经做好了,D表示完成我正在做的事,也就是还没完成,完成之后才去看老师
8.选A,这里的which指代Most people usually have money,这样句子更简洁
9.选A,who在think（动词后）用whom.你认为谁是这条街上最富有的人···
