看到这种大段大段的选项最头疼了

老师，一直看不了课程，老师有空的时候能帮忙调整下吗

neither "lake" nor "water" would be a legitimate referent for this modifier -- you couldn't say "the lake is more than...", but neither could you say "the water is more than..."
this sentence will only make sense if the modifier is allowed to modify the preceding clause, which talks about holding water (because "holding more" actually makes sense).

More than 300 rivers drain into Siberia's Lake Baikal, which holds 20 percent of the world's fresh water, more than all the North American Great Lakes combined.

(c) amount修饰不可数名词，不能用来修饰4,000（drive-ins）这个可数的量。

was injured!

e.g.
i solved all the problems in OG12 in preparing for the GMAT.
--> notice that solving the problems IS ACTUALLY PART OF preparing for the test.

choice (c) fails here, too, since organizing the campaign (the main clause) is not ACTUALLY PART OF convincing the government.

The organic food industry has organized a successful grassroots campaign—using Web sites, public meetings, and also mass mailings—that have convinced

平均值和总数之间的gap

粗心！两次，不是三次

没有认真做题嗦。。。不管文章是否看得懂，你总是要认真去看，去找的呀，有时候不能读懂全文是不影响你把某道题做对的。

看DE选项第一反应ABC缺少连词...

注意start up和new companies的同义转换。

C最好，B用to have非常awkard.
又是比较级 than/ compared to | that of
网友笔记：（注意后两句possible的位置）
Dummy pronoun
3.Postpone Infinitive or That-Clause Objects
Right: She made it possible for us to attend the movie.
Right: She made possible our attendance at the movie.
Right: She made our attendance at the movie possible.

要读懂题
on the grounds 因为
这道题tricky的地方在于问题的问法——文章论点是易受攻击的，因为文章认为……
接下来的选项应该是讨论文章的逻辑漏洞，直接问你GAP是什么。
P——大家喜欢做高凳子看名人
P——大家再高凳子上不会多做逗留
C——引入高凳子会让饭店的收入增加
人们有理由相信那些坐在hollywod的stool上的人不是typical的，他们并不会逗留很短

考察比较级，首先more than这里不一定拆开用，且“than it is for”中的it 错误，这里比较级所以应该用that指代。

笔记：
分词短语in fact possibly serving as an approximate thermometer是伴随状语，在逻辑上，这个伴随状语应改为合句and it can in fact serve as an approximate thermometer，这是本题的一大难点。很多同学可能会认为“伴随”也可以表示因果啊，为什么这里不可以呢？实际上，伴随所表达的因果是一种自然而然的因果，例如：
Jack kicked the post, feeling pain.
“感觉疼痛”是“杰克踢杆子”的自然而然的结果，所以“感觉疼痛”用了伴随状语来表达。但在本选项中，“实际上可以做温度计”显然不是“叫声随着温度而变化”的自然而然的结果，因此不能用伴随状语来表达。

首先AE不对，这个策略/目标既不是无效的或者作者拒绝的；然后排除互相支持的说法BC，即note that the argument recommends a strategy (the second boldface) that contradicts what the businesses are doing in the first strategy. therefore, that consideration is not "support" for the strategy at all -- it's an inferior practice that the strategy actually contravenes. (notice that the follow-up statement starts with "But", emphasizing this contrast.)
本题选项设置较为微妙。

AD两项都错在because of the participle placing, which wrongly indicates that this trend is already placing more women in leadership positions
A还有错的原因是 this fall的位置，可以用来修饰整句，表示今年秋季被认为，也可以用来修饰今年秋季入学的学生。
ultimately蕴含有发生在未来的含义，所以应当搭配将来时，所以是will ultimately place【来自曼哈顿语法Chapter10】
ultimately通常要搭配will来表示未来
注意点：ing的现在进行含义；将来时态；时间副词位置防止歧义。

B项提到了节省时间这一点，至于是不是属于维护工作，不要妄加推测。E项明显与目标无关。
