prep我真是对你狂无语，牛牛们帮我看看吧，救命了~~~~(>_<)~~~~

AmyGMAT

今天起来做了几道语法题，真是狂郁闷，狂无语，我所熟悉的语法现象全都没用到，都不对，啊啊，真想撞墙了，不知道是我语法真就这么烂呢还是这些语法题就是那么BT，本来我 对我语法还挺自信，做prep以后打击的我抬不起头来，各位大牛们帮我看看吧。。。看看我是思路有问题呢，还是基础不行？谢谢了谢谢了！！

The Chicagoand Calumet

Riversoriginally flowed into the St. Lawrence by way of Lake Michigan,

but having been redirected byconstructing canals so that the water now empties into the

Mississippi

by way of the Illinois River.

(A) Rivers originally flowed into the St.Lawrence by way of Lake Michigan, but havingbeen

redirected by constructing

(B) Rivers had originally flowed into theSt. Lawrence by way of Lake Michigan, but theyhave been

redirected by constructing

(C) Rivers, which originally flowed intothe St. Lawrence by way of Lake Michigan buthave been

redirected by the construction of

(D) Rivers, originally flowing into theSt. Lawrence by way of Lake Michigan, buthaving been

redirected by the construction of

(E) Rivers, originally flowing into theSt. Lawrence by way of Lake Michigan, havebeen redirected

through the construction of

句子结构：… Rivers,flowing…, have been redirected through… so that …

主语是rivers，由现在分词结构flowing…作定语修饰，谓语是have been redirected。

考点：句子结构、有效用词

1)        句子结构，在主从复杂句子中要注意主句和从句的主谓结构是否齐全，常见的错误选项是缺少主

句谓语。

2)                                                   有效用词，by doing与by+noun.       在语法上都正确，但前者强调动作，后者强调结果，在GMAT语

法中，通常是by+noun.是正确表达方式。 关于这点的解释我真的很无奈，昨天刚刚看到“because，by doing用法优先，我还记了下来，背过了，放在这里怎么又成了by+n.是正确的表达了。我这个汗啊！！！

还有，我们不都一直说忠于原文么，原文的逻辑意思不要改变，所以这题我很自然就想啦，原文是个转折意，那么选项也应该是，结果错了！

Besides adding complementary flavors tomany foods, hot sauces stimulate the release of

endorphins in the brain, just as exercisedoes, and these have a pain-relieving effect like

morphine's.

(A) hot sauces stimulate the release ofendorphins in the brain, just as exercise does, and these

have a pain-relieving effect likemorphine's

(B) hot sauces stimulate the release ofendorphins in the brain, like exercise, and they have a

pain-relieving effect that is likemorphine

(C) hot sauces and exercise bothstimulate the release of endorphins in the brain, and they have a

pain-relieving effect like morphine

(D) the release of endorphins in thebrain is stimulated both by hot sauces and exercise, and they

have a pain-relieving effect likemorphine's

(E) the release of endorphins in thebrain is stimulated by hot sauces, just as with exercise, and

these have a pain-relieving effect likethat of morphine

这个我更无语了，我是上来就把带these的给排了，虽然我觉得they在这里也不是那么好，可是these错的太不能原谅了啊，不能做主语啊！！现在给出的解释又是these指代前面，可是我明明记得以前的题里面，these也都是有指代前面的某个词的，可是不管怎么样它都不能单独做主语啊！！！

~~~~(>_<)~~~~ 大家快帮我解答解答吧！！

不好意思大家，是我疏忽了
语法中只有说是this/that不能做主语，不能单独存在。
而从来没有说过these/those
所以说上面那样单独指代是对的。

AmyGMAT

TO：zhaoyiqing
呵呵 你的意思是E选项不好还是？

AmyGMAT

哎。我觉得那个啥。。第二题的these 应该指代endorphins
其他几个选项明显错误
我昨天看到貌似在GMAT中these和that/those/one/ones/it/they
的作用不太一样
所以我在想是不是那些会产生歧义，而这个不会呢？
因为在刘振民的书里我看到代替那章 没有说到这个词。
所以these会不会就是就近指代呢

是吗？啊 我还真是没注意到这个语法点。。严重疏忽。。。我去查查！谢谢！！

AmyGMAT

第二个题里看题的时候看到你Mark了These就想到了不能单独做主语，不过读了其他的选项可以看出这里应该是省略了Hot sauces；不过这题让我来做的话估计也会选错，确实很纠结啊

当然细看的话也可以发现其他的选项存在着明显的错误，其中B,C选项中把effect 和morphine做了比较，明显错误，改变原文意思；D, E中把逻辑主语改成了 the release of endorphins ，逻辑意思不合理，可以最先排除

以上愚见欢迎拍砖

真是很纠结啊，我估计我到了考场上是看不出来那个these是个省略形式，我肯定把它当最明显最严重的错误给先排除，然后我会觉得剩下的那些也有错误但也忍了~
我现在做prep发现很多题不好掌握到底哪个是错的最严重的，哪个是可以接受的。有的同样的错误在一道题里就是十恶不赦，在另一道题里就是可以接受，。。。艾艾艾 太灵活了。。。真有点驾驭不了。。。
NN有什么好办法吗？

第一题的E不会觉得像夹心饼干么

那个。。咳咳，我是GG..
我刚才又翻了下OG，91题those who....have found ..，我觉得可以借鉴一下，把who clause去掉，那么貌似跟这题差不多，不知道ETS是不是说这种形式在选优情况下是可以考虑的
this that单独用肯定错，这个是没话说，但是these和those到底行不行目前好像还没公论
这题只能说是选取最优了，一道挺恶心题，差不多就那么回事吧，人难得糊涂。。。

这个题我开始也是很纠结E选项中的have been redirected through这里没有用by, 不过看了你附的解释，感觉明了了，下面说下其他几个选项的错误
A选项中having been redirected 不可用来修饰名词，所以错了
B选项中had originally flowed 时态错误，originally表明要用过去时
C选项整个句子缺少谓语动词
D选项包含了A选项和C选项的错误
这样E是5选项中最合理的了
