问题 单项选择题

美国联邦所得税是累进税,收入越高,纳税率越高。美国有的州还在自己管辖的范围内,在绝大部分出售商品的价格上附加7%左右的销售税。如果销售税也被视为所得税的一种形式的话,那么,这种税收是违背累进原则的。
以下哪项,如果为真,最能加强题干的议论

A.人们花在购物上的钱基本上是一样的。

B.近年来,美国的收入差别显著扩大。

C.低收入者有能力支付销售税,因为他们缴纳的联邦所得税相对较低。

D.销售税的实施,并没有减少商品的销售总量,但售出商品的比例有所变动。

E.美国的大多数州并没有征收销售税。

答案

参考答案:A

解析: 题干必须基于一个假设:人们花在购物上的钱基本上是一样的。否则,如果收入越高,花在购物上的钱越多,则销售税并没有违背累进税的原则。因此,A项能有力加强题干议论。

     Busy senior managers need no longer waste time in showering themselves-an Australian company has

invented a suit that can be worn while they wash.

     The suit has been specially designed so that it can be cleaned under the showerhead.There is no need

for soaking (浸泡), dry cleaning-or even soap.

     The Japanese market has taken a liking to the "shower suit", described as "revolutionary" by its owner Australian Wool Innovation (AWI), which is the research and marketing body that represents Australian

woolgrowers.Orders have been placed for 170,000 of the woolen suits.

     The suit could be worn in the shower, although it was probably better to hang it on a clothes hanger

and carry it instead, AWI corporate affairs spokesman Stephen Feighan said."The idea is that you hang it

up and then...you give it a spray (喷雾), and it's dry the next morning, " Mr Feighan said.

     A Japanese researcher working for AWI invented the suit by combining three technologies.The secret

is the best lining (内衬), which allows the suit to dry quickly.The shower suit attracted busy corporate

people, particularly those who often traveled or stayed up late, Mr Feighan said.The airline industry was

also interested.

     Mr Feighan confessed he had not worn one of the suits yet, or tried to wash it in the shower, because

they cut to fit Japanese figures.

     AWI believes that the shower suit will spread from the Japanese market through Europe and India

.Mr Feighan hoped the suit, made from local wool, would be available in Australia in 12 to 18 months'

time.
