根据材料内容选择最佳答案,并将其标号填入题前括号内。

It was one of the hottest days of the dry season.  If we didn't see any rain soon, we would lose everything.

One day when I was in the kitchen, I saw my six-year-old son, Billy, walking towards the forest. He was clearly trying to be as still as possible.   Several minutes after, he had gone into the forest, he ran out again, towards. the house.  This activity went on for an hour, walking carefully to the forest and running back to the house.  I really wanted to know what Billy was doing.

Finally I followed him into the forest.  I found that he was holding a cup of water. He walked very carefully not to drop the water.

I saw a baby deer lying on the ground.  It lifted its head to drink the water in my son's cup.  After the deer drank up, Billy jumped up and ran back to the house to get more water.  When he saw me, he said, "I'm not wasting. " I found that his eyes were filled with tears.

“I know. " I watched the most beautiful heart working so hard to save another life.Tears ran down my face.  As my tear drops began to hit the ground, other drops and more drops and more suddenly joined them   I looked up at the sky.   It was raining.

Some people would say this was all just a huge coincidence  (巧合).   Those miracles(奇迹)  don't really exist (存在).  I would like to believe it was a miracle.   All I can say is that the rain that came that day saved our farm just like the actions of one little boy saved a life.

题型:单项选择题

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、速度随季节和年代的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的方向,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。海水中溶人了各种各样的物质,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。

与第一、二段所提供信息内容不相符合的一项是()。

A.洋流可分为表层流和深层流两种

B.表层流流速较快,而深层流则由于结构复杂而流速缓慢

C.表层流的发生及其流动方向离不开各种力的作用

D.科里奥利力是由地球自转而产生的,它影响洋流运动的方向
