To Josephine Baker, Paris was her home long before it was fashionable to be an expatriate, and she remained in France during the Second World War as a performer and an intelligence agent for the Resistance.
排除AB:划线内外的一致性，划线外说的是and she remained in France（描述的是一个动作）所以前面也应该是一个动作 排除E：it was 和being的不对应（话说being到底会对句子起什么作用呢） 在C,D中纠结 然后看到D的long before it was fashionable to be an expatriate,后面紧接的是josephine Baker,就觉得那个it 错误的指代了josephine baker. 所以选了D 不过现在看回C那个 to be an expatriate was fashionable 也很奇怪。

Retail sales rose 0.8 of 1 percent in August, intensifying expectations that personal spending in the July–September quarter more than doubled that of the 1.4 percent growth rate in personal spending for the previous quarter.
感觉D的意思也符合整个句子，也是围绕整个句子的意思说的，但是为什么不能选呢，是因为that指代不明吗？

A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. Agronomists studying the growth of this herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert. Hence, the herb’s high histidine production must be the key feature that allows it to grow in metal-rich soils.

In evaluating the argument, it would be most important to determine which of the following?
疑问：为何选B，related group of plants怎么翻？ B选项中说的是其他的植物是不是也大量产生H。老管上课讲，如果提到了原文之外别的东西，又没说这个东西和原文的联系，就错，所以排除了。 C提到了H和酸的关系，这个是原文提到过的，所以就选了C

Which of the following best completes the passage below?

When the products of several competing suppliers are perceived by consumers to be essentially the same, classical economics predicts that price competition will reduce prices to the same minimal levels and all suppliers’ profits to the same minimal levels. Therefore, if classical economics is true, and given suppliers’ desire to make as much profit as possible, it should be expected that ______________.
我的思路： 看完全部原文之后，留下一个印象是价格低，profit低。怎么才能盈利呢？ A:在拥挤的市场中，不同的价格，产品相似。（起码第一句提到了产品相似呢。选） C：在拥挤市场中，每个供应商都要试着去说服消费者，他们自己的产品和竞争者的产品差别是很大的。（原文就没有提过这个啊？）

To reduce waste of raw materials, the government of Sperland is considering requiring household appliances to be broken down for salvage when discarded. To cover the cost of salvage, the government is planning to charge a fee, which would be imposed when the appliance is first sold. Imposing the fee at the time of salvage would reduce waste more effectively, however, because consumers tend to keep old appliances longer if they are faced with a fee for discarding them.

Which of the following, if true, most seriously weakens the argument?
A：提升处理成本，会可能提高动机去不正当的抛弃他们。（认为无关） B：这个额外的花费，不能使得生产商被激励着生产更持有耐用的产品。（不能更持有耐用，所以这个东西该扔还得扔）

In the past the country of Malvernia has relied heavily on imported oil. Malvernia recently implemented a program to convert heating systems from oil to natural gas. Malvernia currently produces more natural gas each year than it uses, and oil production in Malvernian oil fields is increasing at a steady pace. If these trends in fuel production and usage continue, therefore, Malvernian reliance on foreign sources for fuel is likely to decline soon.

Which of the following would it be most useful to establish in evaluating the argument?
看最后一句话：M现在生产的气比国内能用了的要少，并且M的油田也以一个固定的速度在增长。如果这些发现资源、使用资源的趋势能够保持下去，因此M依靠于进口资源将会减少。 D：油的数量M用于生产电，以及能源用于运输，会增长吗？（原文都说了如果发现资源、使用资源的趋势能够保持下去了，这句话是在对假设进行质疑。本来假设就是个假设，不应该质疑啊？） E：有没有什么现存的燃油加热系统，存在与M的，已经转换成了天然气供热系统了？（是否转换了，会使得对能源的利用，有变化）

Rye sown in the fall and plowed into the soil in early spring leaves a residue that is highly effective at controlling broad-leaved weeds, but unfortunately for only about 45 days.  No major agricultural crop matures from seed in as little as 45 days.  Synthetic herbicides, on the other hand, although not any longer-lasting, can be reapplied as the crop grows.  Clearly, therefore, for major agricultural crops, plowing rye into the soil can play no part in effective weed control.
 
The argument is most vulnerable to the objection that it fails to
原文好长，所以只看了最后两句：SH虽然不能维持很长时间，但是可以应用当庄稼生长的时候。因此，对于主要的农作物，用R在土里不能做到有效的杂草控制。 D：原文错在同意这个可能性，去结合两个杂草控制的方法，原文提到的。（因为只看了最后两句，不知道有两个控制方法，排除了） E：原文错在同意这个可能性，植物而不是r,控制在相同的方式，会有相同的影响。（好歹R在原文是提到过的，选之）

During the month of May, crabs arrive on Delaware's beaches to lay eggs.  Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds.  Delaware's crab population has declined recently.  This decline, however, poses no serious threat to the migrating shorebird populations:  by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.
