     "Few things help an individual more than to place responsibility upon him, and let him know that you
trust him." These words are from the black American educator, Booker Washington.He was saying that,
"If you want people to grow up, you have to stop treating them like children."
     In America, families are close but children are encouraged to be independent, to make their own
decisions, even at a very early age.It's not unusual for a child of seven to be given an allowance  (津贴)
every week.The child is encouraged to save some of the money but he or she can spend it on whatever
they choose, for example, buying clothes, school supplies or CDs.Some teenagers even have their own
credit cards!That's a big responsibility since even adults are tempted tooverspend when they have credit
cards.
     From an early age, American children are asked for their opinions and they are included in family
decisionmaking.At the dinner table, teenagers will be listened to on any topic, from politics to buying a
new family car or where the family will go on vacation.In this way, teenagers are getting practice in
becoming individuals:they are learning how to stand on their own two feet.
     Many Chinese young people are becoming almost as interested as American teens in searching for
independence.They want to express those qualities that make them unique human beings.You can see
this in the way they dress, the music they listen to and the friends they choose."Super Girl" Li Yuchun
caught the imagination of Chinese teenagers on the "Super Girl" television contest.She was not the
traditional "nice, young Chinese girl". With her short, spiky hair and boylike clothes, she was telling
everyone that she was different.She had the courage to be her own person and to stand on her own two
feet...and she won!
     There is an old saying, "Everyone should carefully observe which way his heart draws him and then
choose that way with all his strength." If you do this, step by step, over a period of time, you may find
that you have become the person you always wanted to be.

阅读下面短文,回答下 * * 道题。
基于潮流和波浪而产生的周期性流动以外的、比较固定的水流叫洋流。海水会经历几十年甚至数百年的时间在全世界的海域中循环,洋流指的是这种地球规模的海水循环的一部分。在洋流中,有像陆地上的河流一样幅度较窄而流速快的,也有幅度无限宽广而流速缓慢的,其大小、强度不能一概而论。以代表性的洋流之一——黑潮为例,在强流带时可达到2.5米/秒的速度,水流的路径、速度随季节和年代不同都会发生很大变化。一般意义上的洋流,是在大海的表层流动(表层流),而深层的水流则较弱,速度在每秒几厘米以下,水流的结构也很复杂。
表层洋流的发生,首先是因为风。水面上一起风,由于风力作用,水层就被拖动。表层的水一动,因海水彼此之间存在摩擦力,下面的水层便接连不断地被拖动。实际上,洋流并非沿着风的方向前进。像洋流这种地球上的大规模运动通常要受到地球自转的影响,即要受到科里奥利力的作用。在北半球,运动物体所受科里奥利力在其运动方向垂直的右方起作用。这样,海水就偏离了风力作用方向的方位前进,在北半球,表层洋流沿偏离风向约四五度的右方流动。
海面并不是完全水平的,温度、盐分、海水密度等多种因素使得海面凹凸不平。笼统来说,水温高的部分密度小,水面就高,水流理应从高处向低处流,但是由于科里奥利力的作用,高处的水流沿偏右的方向流动,这称为地衡流。海水的盐分等因素也可造成海水密度不同。海水中溶入了各种各样的物质,其中钠和卤素占绝大多数。另外,也有镁、钾、钙等盐类。盐分浓度会随年蒸发量、降水量而发生变化。此外,有河流等大陆水流注入的沿岸海域盐分较少,这些都影响洋流的流向。

下列对“洋流”下的定义,最准确的一项是:

A.基于潮流波浪而产生周期性流动以外的、比较固定的水流叫洋流。

B.由于潮流和波浪而产生周期性流动的,幅度宽窄、流速、大小强度均不同的固定水流叫洋流。

C.洋流指的是几十年甚至数百年的时间在全世界的海域中循环运动的水流。

D.不属于由潮流和波浪而产生周期性流动的、地球规模的海水循环中比较固定的水流叫洋流。
