1.        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.

(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

看到关于这个句子的讨论,结果还不是十分满意.

我想起了OG上面出现无数次的if X happens, Y will happen的结构

我觉得如果用if的话,前面就不可以用can be superficial,而应该用will be superficial

而E当中用的是as when, 而when X happens, Y can happen这样的结构肯定是对的,因为见过很多.

不知道可不可以这样解释呢?(主要是因为OG当中每次有类似的题的时候总是拿if X happens, then Y will happen( 或者Y would happens only if X happens等等)来解释,所以我觉得这道题也可以这么解释.

不知道这个看法是不是正确,大家请指正.

E is the best answer.

这里有个逻辑概念：

if x happens, then y will happen. 是一个x->y，x是y的充分条件。

As when x happens, then y can happen. 这里，x不是一个充分条件。

还记得OG里有关于"provided"和"if"的区别的例子。

我做题时也选了C，但是我总觉得逻辑语感上不爽，当然当时我以为as when是啰嗦。

if x happens, then y will happen. 是一个x->y，x是y的充分条件。

As when x happens, then y can happen. 这里，x不是一个充分条件。

偶也是这么想的，但是似乎if x happens后面就必定要用y will happen，是不不有这样的必然性呢？～～

E中each broadcast对吗？

为什么不是boradcasts？
