【題目】下圖所示為局部海域的等溫線, 圖中甲、乙兩處等溫線彎曲均是洋流影響所致。據(jù)圖回答問題。

【1】

A. 甲、乙兩處可能都為暖流 B. 甲、乙兩處一定位于大陸西岸

C. 赤道不可能從甲乙之間穿過 D. 甲乙流向主要受盛行風(fēng)的影響

【2】

A. 甲處洋流對(duì)沿岸具有增溫增濕作用

B. 該圖的中心部分可能形成世界級(jí)的大漁場(chǎng)

C. 乘海輪自北向南由甲至乙一路順流

D. 如果乙處海域石油泄露，則甲處最易受影響

【答案】

【1】A

【2】A

【解析】試題分析：

【1】洋流流向與等溫線彎曲方向一致，若在太平洋上赤道從甲乙之間穿過，則甲是日本暖流、乙是東澳大利亞暖流，甲、乙位于大陸東岸，甲乙南北流向是補(bǔ)償流，A正確、B、C、D錯(cuò)；

【2】圖中洋流是暖流，對(duì)沿岸氣候起增溫增濕作用，A正確；大漁場(chǎng)一般分布在寒暖流交匯處，該圖的中心部分洋流向南北兩側(cè)流，不會(huì)形成世界級(jí)的大漁場(chǎng),B錯(cuò)；海輪自北向南由甲至乙先逆流后順流，C錯(cuò)；乙處洋流向南流，如果乙處海域石油泄露，甲處不易受影響，D錯(cuò)。

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.
