[讨论]如何看待prep

dustinxing

听朋友说prep的材料是真题，故拿来一做，但发觉prep的题目相当不严谨，这边我先抛砖引玉，希望大家把prep上发现的问题一同讨论，以便更深刻的理解各语法点。

prep2－34

34.   (26262-!-item-!-188;#058&003094)

 

Besides adding complementary flavors to many foods, hot sauces stimulate the release of endorphins in the brain, just as exercise does, and these have a pain-relieving effect like morphine's.

 

(A) hot sauces stimulate the release of endorphins in the brain, just as exercise does, and these have a pain-relieving effect like morphine's

(B) hot sauces stimulate the release of endorphins in the brain, like exercise, and they have a pain-relieving effect that is like morphine

(C) hot sauces and exercise both stimulate the release of endorphins in the brain, and they have a pain-relieving effect like morphine

(D) the release of endorphins in the brain is stimulated both by hot sauces and exercise, and they have a pain-relieving effect like morphine's

(E) the release of endorphins in the brain is stimulated by hot sauces, just as with exercise, and these have a pain-relieving effect like that of morphine

答案：A 。如果利用5选2原则的话，我相信绝大部分都会在A、B里面最终确定答案。那我先来分析一下答案

A，明显错误在于后半句的these，单独使用these指代前面出现的hot sauces，此类用法在GMAT中绝对需要杜绝。但此处居然算对，不知道是什么意思？

B，明显错误在于后半句的不对等比较（effect与morphine比较）。

C，D,  E 明显错误在于主句逻辑主语不能与Besides adding complementary flavors to many foods相配

不知道各位碰到此类题，会选哪个答案？

these 和this指代已经不能算是绝对性的错误了

OG和PREP就是law，没有必要执着于这两种材料严不严谨

hmm...這個月的KFC中有2個NN(770)都經過排除法後picked啦一個choice有this做主語.
OG10中有提過不可以(用this做object)...有可能GMAC現在接受這個用法...

我觉得this等代词做主语绝对错这本身就过于绝对，应该以逻辑＋其他项的错误作为评价标准。不可绝对化。

楼主不要再看OG了，现在的SC已经没有哪种用法绝对不可以这样的说法了，OG已经无法代表现在的SC真实情况。

呵呵，不知道你在看哪些材料啊，能否分享一下。目前多见的就是OG，大全（白勇包括在大全中），其他的好像没有了。

These are his grandparents. That’s his father. That’s his mother. That’s his sister.

为什么不能作主语呀？
