1.C 主谓一致当中的看前不看后的原则。还有就是：with , together with ,but ,except ,besides ,as well as
主谓一致当中看后不看前的有：either ... or ; neither ... nor ;not only ... but also
2.C 时间状语从句和条件状语从句的时态关系：主将从现，也就是主句一般将来时，从句一般现在时。
3.C how soon 是多快，和将来时间连用的。
4.D 可以这样来理解，work out th physics problem 所以就没有it .
5.is it 主语是不定代指物，用it 来代；如指人就是单复数都有呀。
6.both sides either 和both 都指两者
7.had great fun 如果是两个空就填had fun ,四个空就填had a good time
8.What an 主要看是名词或代词还是形容词、副词或动词。名词类的要用what ;形容词类的要用how .追问

(3)第六题为什么是What an 而不是what a ?
