就是某个商业区里的折扣店纷纷关闭，因为他们竞争不过Spendless （把它理解为大型折扣店吧）；但作者认为这些店铺不会空置很久，他打了个比方：一个叫Colson的正价店开张以来，它周围的店也纷纷倒闭，但不久就又会有新店开张。 其实这题的问题在于错误类比，S是折扣店，C是正价店；我们已知S周围倒闭的都是折扣店，但不知C周围倒闭的是什么店。 因此，很有可能C周围的是折扣店，它们和C互补，商家认为低价还是有商机，所以一直有人在C旁边开折扣店（B点出了这一点）； 而S就不一样了，S自己是打折店，周围开的也是打折店，它们是同类竞争的关系，之后也不太可能有人在S旁边再开折扣店了。

问的是C的study能推出啥，a说c做这个study就是为了反驳B，显然文章没这么说

原题中6K后面的逗号是没有的，麻烦改进一下，不然很容易误导学生，谢谢

5是怎么个切法

the construction 'to be sold' is passive voice. in fact, the passive voice is necessary here, because you don't know who is going to be selling the books.
(compare the analogous sentence 'there is still plenty of food left to be eaten').
此题用either or 平行考点即可排除BCDE！

A - should be "as many x as y." the "as compared to" is long winded. A also is not parallel and missing a "there"

e.g. the safety of X is not as great as…… vs. X is not as safe as……
the latter of these is definitely better.

possibly 和may 之间无明显差别，应从其他splits突破

choices (b) and (c) both declare that the actual amount of $950 million is "(a) part of a deal..."
that's incorrect; it's the purchase / acquisition of the rival company's color printing division that's part of the deal.
if you use the infinitive "to make", then the computer company is still the subject of the sentence. therefore, in this case you have to use the reflexive pronoun: itself.
in choice (e), "...that will make..." shifts the role of subject to deal, so a reflexive pronoun is no longer needed. in fact, the reflexive pronoun would be absurd in this case, since a deal obviously can't make itself the largest manufacturer in the market.

这道题最后AC中选择了A就是没有读懂这句话想表达的意思。并不认为A是错在proposal不可以say，而是错在intended meaning illogical
EPA的提案对柴油发动机和柴油进行限制，受到了oil industry 的反对，因为他们认为这样的move（即place restrictions）会恶化国内的supply

读完整的句子！！根据后面的单复数判断主语或代词的单复数！

虚拟语气的句子一开头就要是主语！

语意语意！！！！！！逻辑关系！！！

B选项：分词短语causing only a mild illness是伴随状语，其主语为它所修饰的句子的主语，即，experimental subjects。但在逻辑上，引起疾病的应该是 cowpox，而不是experimental subjects。

those for power与cost平行。
另外，E中，plants之后that引导的从句不缺成分，因此不能看作是定语从句，而要看成同位语从句。
