Which of the following most logically completes the argument below?

Twenty percent of the stores in Morganville's downtown shopping district will fail within five years because they will be competing directly with the SaveMart discount department store newly opened in East Morganville.The downtown shopping district has lost business at this rate before and has always completely rebounded.Confidence that it will rebound again from the losses it is now about to suffer is ill founded, however, because __________.



A. the stores likely to be put out of business by direct competition from SaveMart are the downtown shopping district's anchor stores, on whose ability to draw shoppers many of the other downtown stores depend

B. the bus line that has long connected the downtown area of Morganville with East Morganville has a tradition of carrying shoppers who reside in East Morganville into downtown Morganville to shop

C. when the downtown shopping district has rebounded before, the business premises of a failed business were typically taken over by a business of the same kind as had been there before

D. SaveMart's business plan for the East Morganville store is based on earning low profits, if any, during the first five years of the store's existence

E. it is conceivable that the downtown shopping district could shrink substantially without collapsing altogether

82.(28316-!-item-!-188;#058&002977)



When feeding, aquatic birds known as phalaropes often spin rapidly on the water’s surface, pecking for food during each revolution.To execute these spins, phalaropes kick one leg harder than the other.This action creates upwelling currents.Because plankton on which phalaropes feed typically occurs in greater quantities well below the surface, it is hypothesized that by spinning phalaropes gain access to food that would otherwise be beyond their reach.



Which of the following, if true, most strongly supports the hypothesis?



A. Phalaropes rarely feed while on land.

B. A given phalarope spins exclusively either to the right or to the left.

C. Phalaropes sometimes spin when they are not feeding.

D. Different phalaropes spin at somewhat different rates.

E. Phalaropes do not usually spin when food is abundant at the surface.

第一题是一道填空题,其重要的核心思想就是一定要提炼出because之前的精华,前文说的很清楚,SaveMart store就是会让那些compete directly的倒闭,所以,如果一个store可以rebound,说明,他没有和SM store compete,而C the same kind of business就说明还是要compete,不正确,A选项就是正确答案,而B,D,E均与前文中的所说没有关系,其实填空题并不是一类很难的题型,关键是从上文中提取观点,做题的时候可以用前文来检查一下,如果提到,则是正确的,总之一句话,填空题就是要在题干中提取有效信息,题干的话不是白说的

而第二题是support题型中的现象解释类,其答案极其明确,就是取否,题干结论说spin 就是为了below surface下的greater quantities food。那么答案就是not spin 在surface food is abundant。你的选项属于无关选项,1是文中没有提及left 和right, 2是没有和food产生关系。这类题是support题型中最容易预测而且答案最为固定,就是去将结论取否

82题:题型:支持题,支持的对象:hypothesis:p鸟通过旋转可以够到原本够不到的猎物
典型的现象解释文,加强:通常是否定句,假设另外一种情况。
P鸟通过旋转够到原本够不到的猎物,那么对于容易够到的猎物,它们就不用旋转了——E
