请教大全83

83.        Although it claims to delve into political issues, television can be superficial such as when each of the three major networks broadcast exactly the same statement from a political candidate.C

(A) superficial such as when each of the three major networks

(B) superficial, as can sometimes occur if all of the three major networks

(C) superficial if the three major networks all

(D) superficial whenever each of the three major networks（E）

(E) superficial, as when the three major networks each

请问正确选项E出现each后面是不是该接broadcast(s)啊？还有C错是不是就是因为因为if前缺少了逗号？

为什么呢？

In "the three major networks each broadcast", the subject is "the three major networks" and the verb is "broadcast". Here "each" ia just a parentheses插入语; it cannot influence the main sentence. You can omit "each" in such a situation for it only illustrates the subject additionally. See:

We each have an apple.

Each of us has an apple.

C 错在哪里了呢？

是不是不该用if条件句？Although 已经表示了转折句了，所以主句应该叙述的是事实，而不是“如果”怎样。。。。

我只是知道，as when 时as 用法之一，用的比较少，楼上解释的each的用法。我觉得E就应该时对的了，可是还不动C 错哪里了。

顶！我也不知道if为啥不行，这题我也选了C

高手帮帮忙啊
