B: 多了一个a ，会产生是两种drugs的歧义
A：does放在名词后可（preferred）,像B中前置也可。
【copy】如果在平行结构的后半部分，名词后面（注意是后面）跟着修饰成分，则必须！把do / does 放在名词之前
例
than my brother, who has never studied literature, does. --> F
than does my brother, who has never studied literature,. --> T

结论题，是原文中可以推出来的，c选项可以推出来，但是e选项推不出来

D: if you precede a clause with an initial modifier that doesn't have a subject, then the noun IMMEDIATELY FOLLOWING THE COMMA is automatically assigned as the subject of that modifier.
in this choice, you're saying, weirdly enough, that 'this substitution' is 'substituted' for more traditional fertilizers.
把握核心词，C中they 指代the use of sythetic fertilizers， 但原句想要表达的不是化肥的使用会 造成不好的影响，而是加速使用（an increase)会带来问题！

Industry analysts said that the recent rise in fuel prices may be an early signal of the possibility of gasoline and heating oil prices staying higher than usually through the end of the year.

A. of the possibility of gasoline and heating oil prices staying higher than usually through---- 1. redundancy of may and possibility as already pointed out. 2. usually has no verb to modify, a dangling adverb


B. of the possibility that gasoline and heating oil prices could stay higher than usual throughout--- 1. redundancy 2. throughout and through are meaning - wise different.

C. of prices of gasoline and heating oil possibly staying higher than usually through ----- 1. redundancy 2. dangling adverb

D. that prices of gasoline and heating oil could stay higher than they usually are throughout----- throughout and through are meaning - wise different.

E. that prices of gasoline and heating oil will stay higher than usual through -- correct choice

General: All reported speeches are presented in a relative clause introduced by 'that'. Hence D and E are stylistically better than A. B and C.

Through the end of the year means from now until the end of the year, period by period or event by event. As we are in June now, through the end means the rest of June, the entire of July, August, September, and so on until the last day of December. On the contrary, throughout the end of the year doesn't convey any sensible meaning except to refer to the last of the year. The end of the year marks a particular short point of time. There is no meaning in saying throughout that the short period.
Through means from one point to another. Throughout means entirely

理论上，联合国的国际公务员被禁止继续从他们自己的政府领取薪水；但是，在实践中，一些政府只是用生活补贴替代了被他们派去联合国的公务员的薪水。

A：assigned从句就近修饰paycheck，修饰错误
C: having been done容易错，有更优则不选；非限定此处不如限定
D. in place of, is rather unidiomatic. And the "them" is ambiguous.
E. to have been assigned by them, this is grammatically incorrect and changes the meaning.

憨批题目

D：more…as…as 错，more一定搭配than! many times as rare as / many times more rare than……-Idiomatic
BCD结尾的状语和定语从句对应的逻辑主语illogical!
A:due to ……（由于偷猎和栖息地减少），researchers have determined that ……（研究人员确定了……）--illogical

第20题中E: When a foundation was formed 做状语和做宾语的by local residents在句意上会有区别吗？

原因是一件事而不是湿气本身
such...so that 不对

twice后面可以直接接名词，也可以加as much as。

unqualifying :没资格
unqualified：无条件的

stored... 定语修饰treat，主语a scrub jay是单数

contact这里是名词，仔细看题！跟direct形容词形式

vanish消失，把grassy fields和bird比较，都是在消失

such在前句中要有指代对象，such+noun的noun要在前文出现才可以

E选项：连词while不能添加，其使得others as religious havens缺少谓语动词。（连词必须连接两个句子）

这里的double是make twice as great（造成两倍的）的意思，也就是“使increase/growth两倍”，所以本题直译过来是“今年的人数造成了去年增长人数两倍的增长”。因此，严格来讲，并不是“比较”the number of people和“去年的增长”，而是the number of people发出了“造成两倍”这个动作。
the increase in VS the increase of

like跟名词（代词或名词短语），排除A和B；
Like "As in the case of..." and "As is the case with...", this construction can only describe things that have actually happened.
B: star 与hydrogen 比较对象不对等；it 错误地指代hydrogen，应该指代Sun，但在该选项中Sun
是以所有格形式出现的，it 无法指向所有格形式的Sun；被动语态的表达不如主动语态更清楚。
E：As would be the case with any star of similar mass, once the Sun exhausts the hydrogen in its core,it （will expand） into a red giant and（eventually eject） its outer envelope ……

看清，candidate和candidacy

模仿和练习这两个事件是每一代猩猩遗传下去的根本，这两个事件是世世代代猩猩重复的事件，必然是有时间终止点的事件，应用名词形式，而不是ing形式
