问题描述：
The publishers will send you a specimen copy of their new books ______?.
A.when it will be requestedB.when they are requested it?
C.when it is requested D.when requested
这句的的主句是The publishers will send you a specimen copy of their new books吗,那么主句的主语和从句的主语不一致啊,从句的主语怎么可以省略呢
我的疑问是主句的主语是the publishers,而从句when requested的主语是it（a specimen copy of their new books),主从句的主语不一致的情况下,从句主语和谓语怎么能省呢?
答
D
主句的主语是the publishers,而从句when (the publishers are)requested的主语也是,所以从句的主语和谓语可以同时省略.
当出版商被要求时,他们将会送你一份他们新书的样本.
