“decline at” is unidiomatic

From Ron：you can use "that of Y" in parallel to either "NOUN of X" or "X's NOUN".

From Ron：
第二个and 后面有没有that都对，“as long as you can find the corresponding structure in the other part, then the parallelism is fine”

the passive voice is indeed a problem, because it's unnecessary. (remember that the passive voice should only be employed when there's a fairly compelling reason to use it.) in choice b especially, there's also an unacceptably long distance between the passive-voice action (will be greatly reduced) and the agent of that action (by the ...).

one thing you should definitely notice in choice c is the wordiness of 'the government's prediction is'. constructions like that, which can easily be replaced by more compact forms ('the government predicts') with no change in meaning, are ALWAYS wrong. (also, you need the word 'that' after 'is'.)

found in Puerto Rico in 1991和dated at 34 million years old修饰的都是fossils.

非常tricky！！！！ 有former都不对，不能做18年的前主席

as many as 不能和 as compared to 写在一起，造成重复

cut的原型，分词，和过去时均同型!!

同位语，见RON解释：http://www.manhattangmat.com/forums/post35386.html#p35386

是pulsar被observed，discovery被announced

定语和状语

考虑影响export的因素——需求or供给

要看清题目结论是在说，major eruptions

expect sb to do sth，跟allow很像；而expect that一件事的时候就不是关乎具体的人做事了。这里A和B的区别就是，不是女性被期待，而是大部分学生群体被期待

by failing 修饰动名词engaging；动词含义名词形式也可以被状语修饰。

B中，for一般是用来表原因的，to才是表目的的。表达要做某事用to

C中，being表伴随；但青蛙需要3到4年成熟是个常态，是青蛙的属性，并不是在讲一个过程，不应该用伴随修饰。

所以答案是错了吗？

第三段把我彻底迷糊了，本来前二段比较逻辑清楚： 第一段说一种不仅分析变化与连续性，而且考虑了地理位置和职业差别的分析替代了传统历史上女性地位的下降的结论。 第二段，引用PINCHPECK说在 English farmhouse 农业革命和规模扩大减少了女性在该工业的工作，是的女性lose business ability, indenpence and intiative. 第三段是一些学者反驳PINCKPECK将precaptialism 描述为女性的好时光，因为那时候女性也是很少可以支配工作的收入。但怎么话题一转就说虽然女性不去市场上卖cheese了，但买cheese不一定就意味着有收入。DAVID举例说有个essex的man 还要挪用他老婆的cheese sales?
