which没有修饰句子！！！！！！！！！！！！！，而是因为which引导的修饰部分太长，把build这个谓语动词放在最后不符合表达习惯！！！！！我的天呐，解释的啥都是

GMAC有点脑残了，ABD都可以排除掉，CE的话就需要常识(到底是风带来晴朗天气还是高气压带来晴朗天气）来解题了，GMAC觉得是常识。

（续）比如其实正常是写是这样：while a broad area of high pressure, which will bring fair and dry weather for several days builds. 所以你也看到了，划线部分是which引导的从句，老长老长，但是a broad area of high pressure的谓语动词就个不及物动词builds，放在最后确实有点点奇怪。所以E选项把builds放到which前面去了。
BTW，这个题目的大意是：在大面积高气压（这个东西会带来好几天晴朗干燥的天气）形成的同时，Gusty westerly winds将会继续把a seasonably coolair mass带进这个区域。【build表形成的意思】

官方的意思是，E选项的which可以理解为将前面的一句作为先行词，但是建议更好的理解是which以‘a broad area of high pressure’为先行词，因为从句which后面引导的句子太长，他前面a broad area……的谓语就一个单词’builds’，为了不让动词builds离主语太远造成理解不顺，所以，将which引导的从句放到了谓语动词builds后面。对于这种表示“出现、就位、形成”的动词，在不会造成歧义的情况下，可以放在被修饰的名词与定语从句之间，以避免动词在长修饰成分之后出现，造成动词距离主语过远的理解障碍。

usher...to/into...强调动态的时候用into，故直接选E
D选项中building and bring不并列，错误
E选项中which理论上语法角度来讲只能修饰就近名词，这里不太严谨，但要优于其他选项

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.

解释的好烂，which根本不是在修饰句子
这道题是which是修饰最前面的winds，不规范的地方是离得太远了
这句话的语义是说：当大范围的高压形成后, 这个风还会继续带一些cool air进入这个地区，而且会带来几天的dry weather

从意思来看，高气压和风共同形成干燥的天气

摘：”which will 就远修饰a board of high pressure, 因为谓语builds很短。不然句子就要变成：while a borad area of high pressure, which will bring fair and dry weather for several days, builds.了， 头重脚轻。 ----by IrisH ”

A
Gusty westerly winds 【will continue】 to usher in a seasonably cool air mass into the region, as a broad area of high pressure 【will build and bring】 fair and dry weather for several days.没有用主将从现❌
B
【Gusty westerly winds will continue ushering in a seasonably cool air mass into the region】 and 【a broad area of high pressure will build that bring fair and dry weather for several days】❌
Gusty winds 先把冷空气团带进了地区，形成了冷高压，是这个冷高压导致了几天晴朗（fair）干燥的天气
C
Gusty westerly winds will continue to usher in a seasonably cool air mass to the region, a broad area of high pressure building, and bring fair and dry weather for several days. a broad area of high pressure building作为插入语❌
D
Gusty westerly winds will continue ushering a seasonably cool air mass in the region, 【with a broad area of high pressure building】 and 【bring fair and dry weather for several days】and前后明显不平行❌
E
Gusty westerly winds will continue to usher a seasonably cool air mass into the region while a broad area of high pressure builds, which will bring fair and dry weather for several days. which修饰"a broad area of high pressure"✔

现在看这题的E解释真的不太能接受，which可以跳过简单谓语动词builds修饰a broad of area of high pressure或者说pressure，高压带来晴朗干燥天气，没问题

这题不会做...Mark 一下

主句意思：usher in a seasonably cool air mass to the region。——Gusty winds将继续给这个地区带来一个及时的冷空气团
1.will表示continue后面应该是to do，排除BD
2.usher in… int/to赘余 排除ABC
3.continue to和for several days意思相近，不应该放在一个句子里 排除C
4.C翻译：winds会为某region（一个有高压的宽阔area）带来冷气团，并且winds会带来持续的晴朗干燥。但实际带来干燥的是winds带来的高压。
错误-用area同位语指代region？winds为谁带来fair&dry weather？
5.E：wind会为某region带来冷气团，同时builds一个高压area，这会为这个area带来持续的晴朗干燥地区。

这句话的意思是——G风将会继续引导季节性的大量冷空气进入地区，（as/while）形成大面积的高压会（and/which)带来几天干燥凉爽的天气。
在我看来考点是这俩，但是蛮多人说as 和while不是考察重点........
这句话乍一看很难理解到底谁修饰了谁。

如果有选项是同位语和定语从句交替出现的，肯定要保证定语从句修饰一个名词。如果没有同位语的选项，那么which引导的非限定性定语从句，也可以修饰整个句子！！！

in...into You can eliminate options A & B quickly because they are redundant.

A选项：连词as身后是由并列连词and连接起来的合句，即， a broad area of high pressure will build和a broad area of high pressure will bring fair and dry weather for several days. 在逻辑上，能带来几天干燥的天气的应该是前文的两个天气现象，不应是a broad area of high pressure。

E选项：Correct. 本选项在语法和逻辑上均是正确的。值得注意的是，划线部分最后的非限定性定语从句which will bring fair and dry weather for several days在修饰其身前的两个事件的共同结果。

1.while/as 当。。时候，主将从现，while/as后用现在时而不是will
2.winds usher（引导） cool air mass into the region，而不是winds usher in cool air mass into the region
build的是天气现象，不是high pressure

利用定语从句修饰名词，同位语可以修饰句子的原则来考查我们考生判断逻辑主语的能力，这个时候，定语从句自然只能修饰名词，不能修饰句子

要keep learning啊。 定从是绝不可能修饰，想想定语的定语是什么？ 个人愚见：E选项是一个完美倒装。while在本题做subordinator，后面是个独立句。 因为which引导定从修饰a broad area of high pressure（核心词是area）。本句中因为area的定从太长，为了方便读者理解所以把谓语builds放到了noun modifier（也就是定从）的前面。 如果本句还原后是： a broad area of high pressure which will bring fair and dry weather for several days buils.
Takeaway:
本题的正确答案E，在SC中非常少见的出现了倒装。把area的动词builds提前到area的定从前面。所以本题以划线部分后半部分的splits来判断是很容易排除正确答案的。 本题应该选择更容易的句子开头更简单的splits开始解题。
