现在的物理学中加速度的定义式为a=，而历史上有些科学家曾把相等位移内速度变化相等的单向直线运动称为“匀变速直线运动”（现称“另类匀变速直线运动”），“另类加速度”定义为A=，其中v₀和v_t分别表示某段位移s内的初速度和末速度。A>0表示物体做加速运动，A<0表示物体做减速运动。则下列说法正确的是 [ ]

A．若A不变，则a也不变

B．若A不变，则物体在位移中点处的速度比大

C．若a不变，则物体在中间时刻的速度为

D．若a>0且保持不变，则A逐渐变小

Brazil has become one of the developing world’s great successes at reducing population growth — but more by accident than design. While countries such as India have made joint efforts to reduce birth rates, Brazil has had better result without really trying, says George Martine at Harvard.

Brazil’s population growth rate has dropped from 2.99% a year between 1951 and 1960 to 1.93% a year between 1981 and 1990, and Brazilian women now have only 2.7 children on average. Martine says this figure may have fallen still further since 1990, an achievement that makes it the envy of many other Third World countries.

Martine puts it down to among other things, soap operas and installment (分期付款) plans introduced in the 1970s. Both played an important, although indirect, role in lowering the birth rate. Brazil is one of the world’s biggest producers of soap operas. Globo, Brazil’s most popular television network, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy characters living the high life in big cities.

“Although they have never really tried to work in a message towards the problems of reproduction (生育), they describe middle and upper class values: not many children, different attitudes towards sex, women working,” says Martine. “They sent this image to all parts of Brazil and made people conscious of other patterns of behavior and other values, which were put into a very attractive package.”

Meanwhile, the installment plans tried to encourage the poor to become consumers (消费者). “This led to an enormous change in consumption patterns and consumption was incompatible (不相容的) with unlimited reproduction,” says Martine.

I had the meanest mother in the whole world. While other kids ate candy for breakfast, I had to have cereal, eggs or toast. While others had Cokes and candy for lunch, I had to eat a sandwich. As you can guess, my supper was different from the other kids’ too. But at least, I wasn’t alone in my sufferings. My sister and two brothers had the same mean mother as I did.

My mother insisted upon knowing where we were at all times. She had to know who our friends were and where we were going. She insisted if we said we’d be gone an hour, then we should be gone one hour or less -- not one hour and one minute. And she always insisted upon us telling the truth. Now you can see how mean she was.

The worst is yet to come. We had to be in bed by nine each night and up at eight the next morning. We couldn’t sleep till noon like our friends. So while they slept - my mother actually had the courage to break the Child Labor Law. She made us work. We had to wash dishes, make beds, and learn to cook. We had to wear clean clothes and take a bath every day. The other kids always wore their clothes for days. We reached the height of disgrace because she made our clothes herself, just to save money. I believe she laid awake at night thinking up mean things to do to us.

Through the years, things didn’t improve a bit. We could not lie in bed “sick” like our friends did, and miss school. Our marks in school had to live up to expectations. Our friends’ report cards had beautiful colors on them, black for passing, red for failing. My mother, being as different as she was, would be satisfied with nothing less than ugly black marks.

As the years rolled by, first one and then the other of us was put to shame. We graduated from high school. With our mother behind us, talking, hitting and demanding respect, none of us was allowed the pleasure of being a drop-out.

My mother was a complete failure as a mother. Out of four children, a couple of us attained some higher education. None of us have ever been arrested or divorced. Each of my brothers served his time in the service of this country. She forced us to grow up into God-fearing, educated, honest adults. I am now trying to raise my three children. I am filled with pride when my children call me mean. Why? Because now I thank God every day for giving me the meanest mother in the whole world.
