1.条件状从，不能用when，应用if
2. possibly改变了原句can的意思
3.correspondingly increased sales，correspondingly 状语修饰accompanied，相应地伴随增长，错
corresponding increases in sales，corresponding 定语修饰increases，伴随相应的增长，对

4.unaccompanied，没有not accompanied顺
5.C：were，can时态不一致

意思是整数j的质因数是不是比k的质因数大！

C:在随后的一项研究中，消费者认为性能风险较低的产品的定价高于先前研究中价格最高的产品。

前置定语是永久属性！two -year low level是说这个level2年一直这么low

the principal objection here is that the meaning is incorrect/unclear: for instance, a 'two-year low level' could mean that it hit a low level and then stayed there for two years.

e选项，应该是with the aim of doing吗？还是因为with 结构如aimed at doing更好？
另外的问题在于，aimed at decreasing 做policy的后置定语，policy 是aimed动作的发出者吗？这样logical吗？

it was 与it served as 的区别吗？

Choice A, on the other hand, correctly captures the intended meaning of the sentence: The government is making a general prediction (it's not a prediction aimed at anybody in particular), about the rate cuts that will be experienced by certain individuals.

C：如果宾语从句主句谓语动词与that从句之间有插入语，that不可省略；
The problem with choice E is in the placement of the modifier ("For consumers and businesses making a large number of..."). Since this comes before the main clause, "the government predicts...", the implication is that the government is making a prediction for the sake of those consumers and businesses: the prediction is "for" them - and may not even mean that their rates will fall!

该题为加强题，方案推理题。从方案可行性上考虑。只有在折扣大于设备售价的时候，客户才会愿意接受这个方案。

在DE纠结，还是错选E。求解答

这是一个加强题，要找能够加强因果联系的答案。因果联系为，『交通警察搜车能搜出重案的证据，从而帮助破解重案』，答案C说，『犯重案的人，不太会遵守交通法这种他们觉得不太重的法律』。但C选项的难点在于句子比较难看懂。
很多人以为unwilling是修饰crime的，其实你看到are这个谓语动词接的是in committing such crime，你就应该意识到这是倒装句，唯一合适的句子动词是 unwilling，整句为
Those willing to break the law to commit serious crimes are often unwilling to observe what they regard as the lesser constraints of traffic law in committing such crimes.

这是一道Justify conclusion题，要找支持结论的premise。 文中的特殊牛奶，因为法案要求贴标签，客户可以识别出来，而面临销量下降的风险。结论却说，即使没有这条法令，销量也会下降。最有可能的原因还是客户可以识别出这种牛奶，选项C给了解释，特殊牛奶虽然不用贴标签了，但是普通牛奶缺可以贴标签让自己和特殊牛奶区分开来，故正确。

A的主句是the intellectual quality would diminish，C的主句是the use would diminish the intellectual quality，明显C更合理

as 是介词，后面跟名词。

there are lots and lots and lots of words like this in english. (e.g., I like to taste foods from different countries; These foods taste good.)

it's in the present tense because this statement is still (and always will be) true -- that's where the origins of those alphabets lie.

RISING是定语，RAISING才可能是动名词

expect: 认为某事会发生，约束力强
