as身后直接为“in the most other developed countries”这一状语，说明省略了主句部分，但前面的主句部分直接copy过来就成了“Linking arrangements between secondary schools and the workplace never evolved in the most other developed countries”。其字面意思为“学校和工作的联系在其他发达国家也从未发展”。但合理的意思应该是在美国没发展，但在别的国家发展了。

即便c选项在语法上无错误，但扭曲的原句语义

同时省略 could be, reduce 应用被动

无逗号 v-ing 和 无逗号+从句 都修饰就近名词，因此advocating修饰reformers没问题

as the means of 固定搭配

“continue to do” means “start doing something again that was previously interrupted”, whereas “continue doing” means “to carry on the same thing you have already been doing”.

E选项，and前后不平行，这是因为，前者是同位语，后者是定语，两者的功能不同（如果两者都是定语，则可以平行），所以不能用and连接。
****and做连接词，功能结构都必须平行***

【Standard deviation and Mean 类型题】

mean=（70+ 75+ 80+ 85+ 90+ 105+ 105+ 130+ 130+ 130）/10=100;
1 standard deviation 即范围在[100-22.4,100+22.4]------>[77.6,122.4] 找小于这个区间的数，只有2个；

took 4 freaking 4 mins to get this questions right. "CLEARLY" ---not so clear to me lol lol

choice a is a run-on - it tries to have two main verbs without using any sort of subordinating element. if you take out modifiers, adjectives, etc., you're left with the following: the settlements were built with structures were connected. that's bad.

choice b is correct: it uses a nonessential modifier set off by commas ('of up to 600 rooms each'), which, if eliminated, yields the intact and legitimate sentence ...carefully engineered structures, connected by... (with another nonessential modifier).

choice c:
- 'scale of' doesn't make sense
- you can't say 'each that had...' (can't follow 'each' with a relative pronoun - if you're going to use a relative pronoun, it has to come directly after the thing it's trying to modify)
- no justification for using the past perfect ('had been') - that verb, if there's a verb there at all, should be in the simple past (the same tense as everything else in the sentence, because everything described in the sentence is contemporaneous)
- it doesn't make sense to use 'each' AFTER the comma, because it's not true that each structure was connected with a road system. instead, the road system connected all of the structures with each other, which is nowhere close to the same thing. (having 'each' BEFORE the comma makes sense, because it's actually true that each of the structures comprised up to 600 rooms.)
analogy:
the USA comprises 50 states, each of which is united by a federal government --> wrong (the implication is that each state has its own federal government)
the USA comprises 50 states, all of which are united by a federal government --> correct
the USA comprises 50 states, (all) united by a federal government --> correct, whether you have 'all' or not

choice d:
- 'scale of' doesn't make sense
- the use of AND sets up ostensible parallelism, but the two structures given aren't parallel (one starts with of and the other with with)

choice e is also a run-on sentence (you'll see this if you reduce it to its 'skeleton', a la choice a)

我还以为freezer是品牌名呢。。

D 第一点 are在前面找不到平行的结构 如果要用are的话 前面应该是 prices of xxx are xxxx than they are.....
第二点 我是从指代上发现的 因为虽然都是prices 但其实不是同一个prices 应该用those 来描述一个new copy 不知道对不对呢

DE主要区别在于中文意思的理解上：
D是指公司在预防员工生病这个事情上面省钱
E指的是公司利用预防员工生病这个手段省钱

第三题的解析有点差了

句意为there were no female writers like Jane Austens or Bronte sisters，所以用复数

考试的时候会不会有按钮能筛选数据T-T这不大可能肉眼算出答案来呀

shirla说professionals有优势，ron反驳说但这意味着他们已经很长时间没有达到业余比赛更严格的技术标准了。意思就是没优势。所以两人在说这样的比赛公不公平，谁有优势A说两者是否应该一起比赛，无关Bprofessionals分数是否应该调整去反应专业的优势，分数调整无关 C说变成professionals的事，无关 D professional figure skating competition 和 amateur figure skating competition 谁的 technical standards 更高，无关 只有E说了他俩比赛时 professionals有没有优势

passage2 最后一题E选项文中第二段哪句话表明这个model仍然有效啊，看下来整段都是解释是由于地缘因素导致的inconsistency

passage5 第二题A选项，没搞懂文中哪里体现了productivity are great enough to benefit firms这个意思

passage5的第一题B选项有点没搞懂，Reducing the hours of existing workers怎么就能increase the number of available jobs了，ameliorate unemployment也可以理解为就业率的增加吧，怎么就能得出job number上升了

A. 时态错误，主句时态是announced，宾语从句中变成一般现在时了
B. 时态错误，主句时态是announced，宾语从句中变成一般现在时了，account for是解释说明...的原因
C. right，不了解announce后面的that在主语宣布自身信息时是可以省略的。这里Corporation宣布的是关于他自身的消息的
D. 短语错误，只有
1. announce (that) Clause
2. announce sth
3. announce sth to sb
4. announce to sb sth
没有announce to do的用法！！！
E. having poor sales只能动名词做announce宾语，such that引导的状语从句与主句没有关系，不是声明导致店铺关闭的
