问题 单项选择题

在没有特别说明的情况下,通货膨胀一般是用消费者价格指数(CPI)衡量的物价涨幅,这主要是因为CPI是根据一国消费者最终消费支出的商品种类和权重编制的价格指数。该指数量直接地影响居民收入的真实购买力。政府从维护居民福利的角度看,没有哪个价格指数比这个指数比CPI更合适。更体贴民意了。而食品价格波动主导了中国的消费者价格波动,这不仅是因为食品价格在商品篮子中超过三成以上的比重,更重要的是食品价格本身的剧烈变动。故而关注食品价格波动成为研究中国通货膨胀的重中之重。 对这段文字概括最准确的是。

A.说明在中国食品价格为何成为研究通胀问题的焦点 

B.分析控制食品价格波动对中国国计民生的重要意义 

C.解释食品价格波动如何对消费者价格指数产生影响 

D.强调提高居民的真实购买力应从控制食品价格入手

答案

参考答案:A

解析:解析 根据提问可知本题属于表面主旨题。 文段前两句话介绍了CPI的定义和作用,属于背景铺垫。由关联词“不仅”“更重要的是”“故而”可知,最后一句话的最后一分句是文段的重点,主要说明了,食品价格波动成为中国研究通货膨胀的重中之重的原因,A项最为全面准确。 B项错误,文段只说了关注食品价格波动,并未提及“控制”;C项对食品价格波动带来的影响,属于背景铺垫部分,不是重点;D项文中未提及,属于无中生有,延伸过度。 故正确答案为A。 考点:表面主旨题

     A lift is very useful. It looks like a small room. It goes up and down all day.Sometimes a worker

stands in the lift. He or she operates(操作)it up and down. In modern lifts there's no worker. People

walk in. They know which floor they want to go. They push a button(按钮)and the lift goes to that floor.

It's very fast and easy.

     Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe

it has fifty or more. Who can walk up all the stairs(楼梯)?Maybe people can climb them once. Can

someone climb thirty floors to an office every day? Can small children walk up to their rooms on the

twenty-fourth floor? Can their mothers or fathers carry food up to all those stairs? Of course not.

     We can have very high buildings because we have lifts. We could not have all the beautiful tall buildings without lifts. Because it is too tired for people to climb the stairs every day.
