Due to poaching and increased cultivation in their native habitats, researchers have determined that there are fewer than 100 Arabian leopards left in the wild, and that these leopards are thus many times as rare as China's giant pandas.

(A) Due to poaching and increased cultivation in their native habitats, researchers have determined that there are fewer than 100 Arabian leopards left in the wild, and that these leopards are thus many times as rare as

(B) Due to poaching and increased cultivation in their native habitats, there are fewer than 100 Arabian leopards left in the wild, researchers have determined, making them many times more rare than

(C) There are fewer than 100 Arabian leopards left in the wild due to poaching and increased cultivation in their native habitats, researchers have determined, which makes the leopards many times more rare compared to

(D) Researchers have determined that, because of being poached and increased cultivation in their native habitats, there are fewer than 100 Arabian leopards left in the wild, thus making them many more times as rare as

(E) Researchers have determined that, because of poaching and increased cultivation in their native habitats, there are fewer than 100 Arabian leopards left in the wild, and that these leopards are thus many times more rare than

我记得...time后面只有两种表达：....times as...as 以及....times the+n.  而且加more than是错的。这里堂而皇之的当了答案。不理解！

Scientists at the Los Alamos National Laboratory have succeeded for the first time in mining heat
from the Earth's interior and producing energy on a commercial scale, enough for efficient
generation of electricity and heating factories and homes.

(D) to produce energy on a commercial scale, enough for generating electricity efficiently and for
heating

我记得so...that   so....as to 与enough to常常混考。enough to是必错的，因为主观。可是这里又是为什么啊。。。

The application of a new method for analyzing the chemistry of tooth enamel allows scientists to
examine molars of prehuman ancestors and determining that their diets were more varied than had
been supposed.

(E) Applying a new method for analyzing the chemistry of tooth enamel, scientists have examined
molars of prehuman ancestors and determined

这里不是for doing不好么？为什么又用了呢？而且不论表目的还是和apply连用，都是to do更好啊？

为什么prep把我以前很多判断标准都打乱了呢？还有一周考试了，大家帮帮忙!

165:这个问题难回答，之前没有见过这种表达。Prep里面解释是...times+more+adj+than, ...time as + adj + than都正确

44：新东方结论说enough出现一定错的。到Prep这题才发现不一定。

但是这题每个选项都有enough,GMAT语法永远是选相对正确的。这里D选项最对称。

45：这个还是回答和上面一样，每个选项都有for doing,选相对正确的。

看来真的没有规律，prep真是叫我又爱又恨，发现本来建立起来的敏感问题好多都不成立了。。

你之前那些规律，(一定错的词，一些优选结构等)。我觉得应该这么理解,在2个选项之间其它部分都一样的时候，再用此规律比较保险。

新东方总结出来那些规律，用起来真得小心。

Prep中似乎强调平行，对称，逻辑，代词等问题，靠实力去解题保险咯

这个more adj. than 和more than还是有差异吧

more adj. than中的more是修饰adj的，上面的many times more rare than 和我们常见的.. times more than的错误不同，细细体会一下

也就是说times more than的more与times重复，但是本题中more是形容rare的？是么？还是有点别扭

那啥，，，我也选的是many times more rare than，但是我选的是B。为什么B不对呢，researchers determined不可以做插入语么？

B中后面的making有没有问题先不说，前面的due to就不对。前面的现在分词poaching and increased cultivation 没有逻辑主语。难道是there are?
