白勇语法里我记得说these/that/this/这样的词不能单独用来做主语呀?这么看是可以的呀?

请NN们解释一下什么情况下these/those这样的指示代词可以做主语吧~~~~

我用这一点直接把A排除了...很勉强地选了B,但是现在觉得B里面like excercise的位置确实很微妙,而且they指代不明也.说affect that is like morphine也不对....

LZ，朗文字典的解释
this1 S1 W1 [See pronunciation table in "How to use dictionary" pages] plural these [See pronunciation table in "How to use dictionary" pages]
1XX used to refer to a person, thing, idea etc that has just been mentioned or to something that has just happened:
例句：
This will be discussed in the next chapter.

我没看过白勇，但是this/these不能做主语这种说法太绝对了，
小学英语就学过“This is an apple”, this怎么会不能做主语呢？

只能说this和these做主语在GMAT中貌似真的不常见。
