问题解答：
我来补答
not only.but also 不仅.而且.连接词
再问： 那do等是不是要放在not only后面，而人要放在not前面？？ 还有一个问题， 疑问句中 “do you think” 是放在句首还是句末，那 “do you know” 呢？ 麻烦你了，谢谢
再答： 不一定 看你连接的是什么 比如： i agree with not only what you said, but also what you wrote on your plan. 和 i not only cleaned the window, but also washed the carpet. do you think/know 作为主句的话放在句首，如 do you think (that) he can finish this task on time. 实际上是一个宾语从句 而放在句中或者句末的话常常是一个插入语 比如 who, do you think , can get the first of the match.
再问：
谢谢你了，好耐心那
