Q3.p2-sc 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
答案是A   可是，these不是不能单独出现作主语吗？这是极大的硬伤啊！！！请大侠们帮帮我吧，快考试鸟~~~

这道题目考的主要是just as和and的区别。Just as是用来比较clause的，like是用来比较nouns的。（你网上可以随便google一下like vs. as）。

These是不能做主语，但是这里是用作指代 hot sauce，由于and的介入使其变成平行结构，they是指代人不是物。

D和E应该上手就排除掉因为“adding complementary flavors to many foods”的主语是hot sauce，而不是releases。

C么结构错误。

可是很多地方都提到，these，this等不能单独指代，this，these+n  才是正确的结构啊！！！
谁说they不能指物的？OG里有很多例子啊。。。OG verbal 16   Iguanas  have been an important food resouce in Latin American ......and they are still prized as game animals.......

嗯，这道题目有人在manhattan gmat上争论过，也是因为pronoun ambiguity，认为these不能stand alone。不过我觉得这道题的考点在like 和 just as的比较上，相对来讲pronoun ambiguity的问题小点，还有一种解释就是these在这里不是指代，而是adjective，是these endorphins的缩写。

不过我觉得你不要过于去钻这个细节，题目的主要还是考察你有没有分清just as 和 like的区别。因为 B 明显没有用对。
