propel和help平行 it...have主谓一致杀E(B也有一样问题)

that不是跳跃指代，是因为that从句太长，后面的谓语太短，为了避免头重脚轻。就把谓语 is being tested 提前了。这样做是为了是主谓语更紧凑。

一看答案就明白了。当时怎么就没有反应过来呢！~~~that不是跳跃指代，是因为that从句太长，后面的谓语太短，为了避免头重脚轻。就把谓语 is being tested 提前了。这样做是为了是主谓语更紧凑。that放在后面是一种无奈的妥协。新东方老师讲过。。。这应该称之为一种另类的倒装。非常够。有一个题记忆很深。应该说的是一种鸟 动词用的bring。结构是bring sth that to sth. 由于that 从句太长，就写做bring to sth that sth.....而且这个题就化纤了bring 一个词。。。。。。记忆很深。不知道大家有没有印象。。。刷过题的同学应该记得的。。。。

看到being就喜欢排连着一起的。其实这道题真的不应该错！！！A,B没怎么看，该打。一定要稳住。很容易的平行啊，句意懂了就一下出来的 啊
