题目内容

【题目】下图所示为局部海域的等温线, 图中甲、乙两处等温线弯曲均是洋流影响所致。据图回答问题。

【1】

A. 甲、乙两处可能都为暖流 B. 甲、乙两处一定位于大陆西岸

C. 赤道不可能从甲乙之间穿过 D. 甲乙流向主要受盛行风的影响

【2】

A. 甲处洋流对沿岸具有增温增湿作用

B. 该图的中心部分可能形成世界级的大渔场

C. 乘海轮自北向南由甲至乙一路顺流

D. 如果乙处海域石油泄露，则甲处最易受影响

【答案】

【1】A

【2】A

【解析】试题分析：

【1】洋流流向与等温线弯曲方向一致，若在太平洋上赤道从甲乙之间穿过，则甲是日本暖流、乙是东澳大利亚暖流，甲、乙位于大陆东岸，甲乙南北流向是补偿流，A正确、B、C、D错；

【2】图中洋流是暖流，对沿岸气候起增温增湿作用，A正确；大渔场一般分布在寒暖流交汇处，该图的中心部分洋流向南北两侧流，不会形成世界级的大渔场,B错；海轮自北向南由甲至乙先逆流后顺流，C错；乙处洋流向南流，如果乙处海域石油泄露，甲处不易受影响，D错。

Last night a strong wind as well as a heavily rain struck our area. News came that the trees in the park two kilometers away from our school was blown down. This afternoon, they set off the park to do some cleaning. The head of the park met us or gave us some advice on how to clear away the falling trees, branches and leaves. Some times later, we were working hard when it begins to rain. Because few of us had taken along umbrellas or raincoats, so we were all wet. A rain lasted about an hour and it was a pity that they had to stop our work.

Nowadays more and more Chinese go to work with bicycle, leaving their cars at home. Why are so many people riding bicycles to work? They have different reason for it.

First, bicycles do not use up any fuel. Therefore, they cost less than other means of transport. Besides, bicycles do not need many space on the road, and it is easily to find a place for it. And everybody knows that riding a bicycle is healthy sport.

When people drive their cars to work or shop, they lost the chance to exercise, but the waste gas from the cars will pollute the air. And moreover, people feel annoying when looking for a parking lot in the busy city center. So I prefer riding a bicycle to drive a car.

We are looking forward to a cleaner and better environment by changing our life style.
