Many teenagers undergo stress, but results of a recent study indicate that the patterns of stress
            that girls experience
            are
            more likely to result in depression than
            are
                those
                that boys experience.

(A) are those that boys experience

(B) what boys experience

(C) boys' experience would

(D) boys' stress patterns do

(E) stress patterns of boys

答案：a

than后面的部分是怎样的语法结构 是主谓倒装么 我这样平行标注对么

B为什么不对 what=something that= the patterns of stress
                that

为什么不对

than前后的成分一定要平行一致.

此题比较的成分是句子,即前面是the patterns of stress
        that girls experience
        are likely to result in depression. 所以than后边对比的一定是有主谓语的句子.

当than后的主语(S)和前面一样时,用that/those代替;
当than后面的谓(V)和前面一样时,用相应时态助词代替.此题时态是are...所以不能用什么do,would之类的.

than后的句子结构用陈述句和倒装句都可.(不过题里倒装挺常见的.)
