there is no reason to suspect that the effect would be qualitatively different than what was seen in the aftermath of the Mount Saint Helens eruption.
there is no reason to believe that A would be qualitatively different than B≠they believe that the amounts of A and B are the same,识别说话人的目的和情境，这里是说人工的会跟自然的差不多或者比自然的还高，而不是跟自然的一毛一样。

do在比较级中是指代前句整个动词的一个缩写，跟指代名词时的it类似。

C. did应该为did so (曼哈顿讲的)

Quote:
C. outline the major questions in a scientific discipline

We can eliminate (C) because the author didn't write the passage to outline major questions. If this were true, we'd see more of an outline-like breakdown of more than one question. Instead, we have a deep dive into a single question ("How do these two groups define behavioral?") and a single example (Shaker) used to address that question.

没有 future likely。 sb is likely to xx。而不是 sb will be likely to do

likelihood that sb will 。。。 makes sense

Manhatten 的 staff如此说：
for those of you who are not native speakers of english - the best approach to problems such as this one is:
* note the differences in usage between the formal and informal
- e.g., "rate how likely" vs. "rate the likelihood that..."
* remember what these differences look like, so that you can make similar distinctions in the future.

that在不在都ok，不是必须不在。

if。。。were。。。，。。。would。。。。

哎呀，看尾不看头。。。。罪过罪过

这个题是经济学，讲的是稀缺性，学生老师有一定比例，学生多了，作者就觉得emmm，找个教教师的工作会很容易。BUT，如果大家都像你这么想，并且人家都是有教师资格证的，那么找个礁石工作还会容易么？no！

(1) The cable company installed three cable outlets in the Horace family home. Total cost=$30+$20*3. Sufficient.

(2) The amount that the cable company charged the Horace family for installing cable television in their home was equivalent to an average (arithmetic mean) charge of the $30 per cable outlet installed. Say the number of outlets is x, then Total cost=$30+$20*x and the average is ($30+$20*x)/x --> ($30+$20*x)/x=30. We can solve for x. Sufficient.

10^x - 74 --> last 2 digits are always 2, 6.

10^2 - 74 = 26

10^3 - 74 = 926

10^4 - 74 = 9926 and so on....

If x > 1,
the sum of the digits --> (x-2) * 9 + 2 + 6. hence, (50-2) * 9 + 8 --> 440.

此段话想说“让它（火蚁，单数）更容易扩散。
A B C 代词问题： A C用了them，不可指代单数的火蚁，便成了天敌们的代词，明显不符语义。
B出现了两个it，分别代表不同含义，指代混乱，非优选。
D完美项
E畸形

有that就是identify两个递进的发现：an asteroid & 一个if句子
没有that就是an asteroid & 一个句子并列，这不可能
ac的时态用法都是对的

简单的句意不要大意
d歧义，对比的是energy produced in France to that produced in Germany, 顺序颠倒造成句意变化：energy produced in France comes from nuclear power in Germany
whereas这类subordinator两clauses结构很宽松，不需要平行，主被动态也不需要一致

倍数关系：A is twice B, 不用A is twice of B
A is sold for 3 times the price THAT sb charges for B 宾语从句直接解释倍数关系
A is sold for 3 times the price OF WHAT sb charges for B 所有格

类比甲：曾经市中心经营不佳的店都又回弹了，乙：现在因郊区打折店竞争经营不佳的市中心店要倒闭，回不来了。
找类比失败原因：1类比对象两者本质不同，2他因
a乙和甲性质不同，乙旗舰店：imply之前回弹的甲是靠乙回弹的
c代替甲的都和甲一个性质：代替乙的也可以和乙一个性质，郊区有打折店城里也可以接着有打折店

对比ab，为什么我就是看不明白，这明明都是在拿spending和rate比啊。。。

However, despite antagonism between bourgeois feminists and socialist feminists, the two movements shared certain underlying beliefs.
however，despite这种衔接词，表示反向的核心态度
c还错在solving a political problem，女权运动的两派，原文没提到过要解决的问题
