比较的题型：1）比两样东西（名词），2）比两个动作（动词）。
这里比较的是两个动作，所以，有一个省略用法 [sub+verb]+modifier，只保留modifier，选C。
如果是比较两个东西, 比如circulation in.... is lower than that in ....，就应该是D。
（newspaper）{had} 《lower circulation》 in the six months than（newspaper）{ had} in a similar period
改写为两个东西比较：the circulation of newspaper in the six months is lower than that in a similar period
如果有两个with，后面的strained to the breaking point就只能修饰第二个with后面的那个名词，语义上就不对了。 比如A，意思就是”因为客户的耐心和马上就要爆了的网络“，”顾客的耐心“到底怎么样就没说。由此可以排除AD。
B：a series of new initiatives that try to relieve...不对，try的主语是initiatives，不是company。
E： try relieving在这里不对，要用try to do
This uses a quite idiosyncratic idiom, involving the verb "to usher." The literal use of this word is the action of the person called an "usher," the person in a theater or at a classical concern who escorts patrons to their seats. Metaphorically, it is used about anything that brings something into existence. The basic idiom is:
I usher X in.
If I want to specify the region in which this X is introduced, I would say:
I usher X into A.
The "in . . . into" is redundant and wrong: choice (A) & (B) have this, and the "in . . . to" in (C) is far from ideal. Choices (D) & (E) get the idiom completely correct.
This is not a strict rule, but "continue" +[infinitive] sounds formal and sophisticated, whereas "continue" +[gerund] sounds casual and colloquial.

Choice (E) is the tricky one. A comma-which modifier refers to a noun and that noun has to be close enough to the modifier that the relationship is clear. In this case, a broad area (of high pressure) is that noun, and it is in fact only one word away from the modifier—but, unusually, a verb (builds) comes in between. A lot of people will cross this answer off because, typically, a verb does not intervene between a noun and a noun modifier.
This particular clause (while a broad area of high pressure builds) is itself a modifier of the main sentence that appears before it. In this case, the author must choose between these two constructions:
… while a broad area of high pressure builds, which will bring fair and dry weather for several days.
… while a broad area of high pressure, which will bring fair and dry weather for several days, builds.
Given the length of the noun modifier—and the shortness of the verb—an author might choose to place that verb first. Think of this as an extension of the convention that a noun followed by two noun modifiers will place the essential modifier first:
The box of nails, which is sitting on the table, …
It’s still clear that the second modifier refers to box, as in choice (E) it’s clear that the which modifier refers to the broad area of high pressure.
【转自RON】关于D
It's nonsense, because "$xxxx in yyyyy" would mean that yyyy is something that can actually be measured in dollars.
E.g.,
By driving a hybrid car, I will save thousands of dollars in fuel costs.
Your business can save over $10,000 per month in shipping costs by using XYZ Courier Service.
【转自RON】句中代词their＆they
those pronouns are in two completely different clauses, so they can absolutely stand for different nouns. as long as the meaning is clear in context, that isn't a problem.
朗文当代：be known to do something-Smoking is known to increase a person’s risk of developing lung cancer.
In more formal English, you say it is known that or it is known who/why/what etc:
It is known that the drug causes infertility. / It is not known how many people were killed.
ab选项还原：that humans made tools is known at the earliest date 意思是known这个事情发生的时间；原句表达的是做工具的时间即推前的是做工具的时间，而不是考古发现证据的时间humans are known to have made stone tools at the earliest date

我自己的理解：
比较的题型：
1）比两样东西（名词）【主句谓语动词是be之类的系动词？】
2）比两个动作（动词）【主句谓语动词是实义动词？】
