涉及主谓一致的倒装有这样一道题: In the letter __________ these words,“I love you”.A. was B. were C. saw D. found此题应选B。选项A,C,D都有可能被误选。对于此题,考生首先要弄清它是一个倒装句,其正常词序为:These words "I love you" were in the letter. 为了结构紧凑和平衡,才使用此倒装句式。又如:轮船上有2000余人。正:On the ship were more than 2000 people. 正:More than 2000 people were on the ship. 值得注意的是,以上这类倒装句,还涉及主谓一致问题:墙后是一些高树子。正:Behind the wall are some tall trees. 误:Behind the wall is some tall trees. 老师四周围着一些年轻的学生。正:Around the teacher were some young students. 误:Around the teacher was some young students. 这两座山之间有一个小村庄。正:Between the two hills was a small village. 误:Between the two hills were a small village. 盒子里有一些小球。正:In the box are some small balls. 误:In the box is some small balls. 这类句子,有的考生之所出错,是因为他们把句首的介词短语看作主语,从而把谓语与介词短语中的名词保持一致。关于这个问题,有个比较简单的方法可以判定:即在英语中介词短语通常不能作主语,假若一个句子的主语位置是一个介词短语,考生应考虑是否是一个倒装句。
