问题 单项选择题

葡聚糖是现在人气极高,食品科学和工业界很看好的一种可溶性纤维。某些葡聚糖也似乎对于增强免疫力更有效果——但是任何的膳食纤维都会对健康大有裨益。与其花钱去买“特别的”、“增强免疫力”的纤维,多吃一些经济实惠的富含膳食纤维的食物是不更划算
根据上文推断,作者接下来最可能讲述的内容是:

A.葡聚糖在众多膳食纤维争夺战中如何获胜
B.消费者如何选择膳食纤维
C.富含膳食纤维的食物种类
D.膳食纤维对人类生活的影响

答案

参考答案:C

解析:文段首先介绍了葡聚糖是业界很看好的一种可溶性纤维,某些葡聚糖也似乎对增强免疫力更有效果的事实,接着以“但是”作转折,说明任何膳食纤维都会对健康大有裨益,建议人们多吃一些经济实惠的富含膳食纤维的食物,接下来,自然要围绕富含膳食纤维的食物展开论述,选项中只有C提到了富含膳食纤维的食物,为正确选项。

单项选择题

Pamela: Business has an interest in enabling employees to care for children, because those children will be the customers, employees, and managers of the future. Therefore, businesses should adopt policies, such as day-care benefits, that facilitate parenting.
Lee: No individual company, though, will be patronized, staffed, and managed only by its own employees’ children, so it would not be to a company’s advantage to provide such benefits to employees when other companies do not.
In which one of the following pairs consisting of argument and objection does the objection function most similarly to the way Lee’s objection functions in relation to Pamela’s argument

A.New roads will not serve to relieve this area’s traffic congestion, because new roads would encourage new construction and generate additional traffic.
Objection: Failure to build new roads would mean that traffic congestion would strangle the area even earlier.

B.Humanity needs clean air to breathe, so each person should make an effort to avoid polluting the air.
Objection: The air one person breathes is affected mainly by pollution caused by others, so it makes no sense to act alone to curb air pollution.

C.Advertised discounts on products draw customers’ attention to the products, so advertised discounts benefit sales.
Objection: Customers already planning to purchase a product accelerate buying to take advantage of advertised discounts, and thus subsequent sales suffer.

D.If people always told lies, then no one would know what the truth was, so people should always tell the truth.
Objection: If people always told lies, then everyone would know that the truth was the opposite of what was said.

E.(E) Human social institutions have always change so even if we do not know what those changes will be, we do know that the social institutions of the future will differ from those of the past.
Objection: The existence of change in the past does not ensure that there will always be change in the future.
