1.主谓一致，E错
2.句意推理,convince后面应该接that，表示一件事，C错
3.idiom:prefer A to B. CDE错
4.句子结构，just as和many travelers应该是并列关系，作比较，所以应该在that后面，BCD错

1.主谓一致，BCD错
2.句意推理，merger是并购的意思，那就应该是两个公司才对,A错，BC有歧义。
3.逻辑推理，CD的独立主格结构修饰的是前面整个句子，这个和句意不相符，这部分本来应该用来修饰market the utilities的。

Much more importantly, "smaller" vs. "less of a" is there just to distract you. You don't actually need it to solve the problem.
* You can eliminate a/b/c because the comparison has two possible meanings: (1) commitment to work vs. commitment to family, or (2) young people's commitment to work vs. their parents' and grandparents' commitment to work.
* You can eliminate E because "than" is there without "less".

E with the remainder of it coming，这里的with作为介词还是连词呢？如果是介词跟名词（独立主格形式）为什么不正确呢？

看题都看麻了， 还以为他干什么呢，下面4个橘子上面就放1个，这样算上层一个都没有。结果是在这堆橘子塔呢

1.主谓一致，E错
2.句子结构,BC没有谓语
3.between and平行，BD不平行
4.view...to be用法错误，BDE错

1.代词指代错误，DE的it都指代的是The growth of the global economy between 1990 and 2000，C的that which更错了，CDE错
2.动词时态，CD时态错误
3.B的from when agriculture began不如A表达简洁。
4.措辞，for 10,000 years错，CDE错。

1.which修饰对象错误，DE错
2.代词指代，it和they的指代都不明确，而且不正确。
这里是比较和省略结合，把比较的名词省略掉。
a greater proportion than（the proportion）（television costs had accounted for of the spending）in any previous election

1.句子结构，AB错
2.动词时态，没有必要用过去完成，E错。
3.修饰词的位置，well-established应该修饰的是Method,ABE错
4.简洁，D不如C简洁。

1.平行,promote前面的动词一定要跟它平行，只有B满足。
2.逻辑推理，注意这里是三者中选一个，explain，reveal，和promote一起平行，所以要用among,ACD错。

1.Idiom,A的so...such that...错，A错
2.逻辑推理，Only位置，AD错
3.代词指代，it指代的是75 percent of the population，句意错，AC错
4.动词时态，B的现在进行时没有必要。
5.句意推理，B的so表示前后因果关系，没有必要。so..that表示强调更好。
6.D有两个谓语，D错。

1.句子结构，没有谓语，BD错
2.代词指代，Athis用错
3.句意推理，平行，barbed和stay应该是一前一后的动作，应该是平行的。ABD错
4.句意推理，C的句意错，刺导致了一个结果？句子表达的不是这一个单独的意思。

1.主谓一致，BD错
2.平行的idiom和平行的对象，CD错
3.简洁表达,AB不好，C错
4.介词的选择，of for和that，AD不好
5.A的EAST前面的that多余。

C: 说明本身这里的人平均年纪就高

A选项：介词短语due to poaching and increased cultivation in their native habitats是状语，应就近修饰一个句子。本选项中其最近的句子为researchers have determined that xxx。但在逻辑上，由于“偷猎和栖息地减少”的，应该是“野生猎豹的数量少”，而不是“调查者确定了xxx”。

CD:我跟你一样的选了B。不过我现在反反复复看了很多遍。觉得问题所在是第一句话的前提上。所以整段话的前提都是为了实现Industrial accidents are more common when some of the people in safety-sensitive jobs have drinking problems than when none do.这个目标。所以非安全敏感地带只能属于无关项了。
E也是一样，out of scope。

anyway,C也不是个什么好选项。假设他们确实hide了。但是并不影响他们的禁令。比如20个喝酒的。19个hide。不禁和禁还相差了一个人。总是对预防由好处的。而且题目问的是undermine the argument，而并非问的是if true, the company will not reach their goal。两者是不一样的。前者是需要整段话的逻辑。反正我觉得这个题愤懑

DE错在that使用，如果 that 修饰records，后面的句子指代records主动要表达的动作或者内容。
原文 proven records 是想修饰 什么样的borrowers (they do not pay pack their loans on time) = records of these borrowers that they do not pay...

such 就是修饰a group 的，应该不是考点
with such a group 错在with，消失了主语

原文 high frequently 原因是prey availability was low, 和 intense competition over kills 等
问题 less frequently 会怎样？
答：prey availability was high = during periods in which more prey were available

请教毕老师，为什么B 是现在进行时，原句子In 2000, a mere two dozen products accounted 是过去式

Locke’s intellectual heirs it was only a short step to the “labor theory of value,” whose formulators held that 100 percent of the value of any product is generated by labor (the human work needed to produce goods)
