1、该题主要考的倒装.B.the children rushed C.they rushed 的区别在与当是人称代词时,就用陈述语气,即they rushed .而若选B为正确答案应改为rushed the children.
2、介词短语位于句首需要倒装.At the head of the procession 其实做的是宾语,marched是谓语 the Young Pioneers是主语.主谓宾很全,句子完整,所以不需要加where .ezch holding a red flag in his or her hand是伴随状语.
3、 the reward for the boy who worked 14 hours a day是句子的主语.当主语太长的时候,一般采用倒装 ,Such 提前指代整件事.
4考察的是虚拟语气的倒装,B.Had it not been 就等于if it hadn't been.虚拟语气的倒装只有三个可以提前,即 had,should ,were.
5将来的虚拟还有should do sth 和were to do sth,A.Were he to come 就是 were to do sth的形式.
