(E) fixes that problem: it just uses the conditional tense “could easily be bought directly”, which makes much more sense with the fact that people “are turning to stockbrokers” now.
So (E) is the correct answer, even if you don’t pay much attention to the idiom.
In (D), we have “stocks that easily could have been bought directly”, and that doesn’t completely make sense, since it suggests that the stocks could have been bought directly – in the past! Then why is it that people “are turning to stockbrokers” now – in the present progressive tense, which can ONLY be used for an action that’s happening right now?
Manhattan: AS如果想表示像... 后面必须是一个句子,e.g. AS we did last year, we will win this year.
而AS直接加名词,表示作为(i.e. =in the role of) e.g. As the president of the company, she works hard.
又是一道模考的时候没有读进去题目的题....
