问题 单项选择题

除了企业购买外,过去5年中购买一辆新的刚刚出厂的汽车平均支出的费用增长了 30%。在同样的时期中,购买汽车的开支占家庭平均预算的比例并未发生变化。因此,在过去的5年中的家庭平均预算一定也增加了30%。
以上论述依据下面哪个假设

A.在过去的5年中,平均每个家庭购买新的刚出厂的汽车的数量没有变化。

B.在过去的5年中,企业平均在每辆新车上的花费增长了30%。

C.在过去的5年中,家庭平均花在和汽车有关的方面的费用没有变。

D.在过去的5年中,家庭平均花在食物和住房上的开支没有变。

答案

参考答案:A

解析: 这是一道计算题。设5年前一个家庭购买每辆汽车的开支是X,购买汽车的总数是n,家庭预算是Y,则n=Y/X。5年后购买每辆汽车的开支是130%X,家庭预算是130%Y。那么,5年后购买汽车的总数n'=130%Y/]30%X=Y/X=n,即在这5年中,平均每个家庭购买新车的数量没有变化,即A。

Three Boys and a Dad

Brad closed the door slowly as Sue left home to visit her mother.Expecting a whole day to relax,he was thinking whether to read the newspaper or watch his favourite TV talk show on his first day off in months.“This will be like a walk in the park,”he’d told his wife.“I’ll look after the kids,and you can go visit your mom.”

Things started well,but just after eight o’clock,his three little “good kids”—Mike,Randy,and Alex—came down the stairs in their night clothes and shouted “breakfast,daddy.”When food had not appeared within thirty seconds,Randy began using his spoon on Alex’s head as if it were a drum.Alex started to shout loudly in time to the beat(节拍).Mike chanted “Where’s my toast,where’s my toast” in the background.Brad realised his newspaper would have to wait for a few seconds.

Life became worse after breakfast.Mike wore Randy’s underwear on his head.Randy locked himself in the bathroom,while Alex shouted again because he was going to wet his pants.Nobody could find clean socks,although they were before their very eyes.Someone named “Not Me” had spilled a whole glass of orange juice into the basket of clean clothes.Brad knew the talk show had already started.

By ten o’clock,things were out of control.Alex was wondering why the fish in the jar refused his bread and butter.Mike was trying to show off his talent by decorating the kitchen wall with his colour pencils.Randy,thankfully,appeared to be reading quietly in the family room,but closer examination showed that he was eating apple jam straight from the bottle with his hands.Brad realised that the talk show was over and reading would be impossible.

At exactly 11∶17,Brad called the daycare centre(日托所).“I suddenly have to go into work and my wife’s away.Can I bring the boys over in a few minutes?”The answer was obviously “yes” because Brad was smiling.(2012·陕西,B)
