题目内容

【题目】 我国水资源总量虽然大,但由于我国人口众多,且水资源分布不平衡,导致我国约四分 之一的省份面临严重缺水问题。

据此完成下列各题。

1我国水资源地区分布“东多西少,南多北少”,依气候知识解释正确的是

①西部为非季风区,降水多

②东部为季风区,降水多

③北方雨季短,降水少

④南方雨季短,降水少

A.①④B.②③C.①②D.③④

2福建上杭县降水集中在春、夏两季,在少雨季节易导致干旱,影响人们正常的生产与 生活,解决这一问题的最佳措施是

A.兴修水库B.跨流域调水C.防治水污染D.人工降雨

【答案】

1B

2A

【解析】

我国水资源的时空分布情况受我国降水的影响,我国降水空间上来说从东南沿海向西北内陆降水逐渐减少,导致我国水资源东多西少、南多北少;我国水资源时间分配上具有夏秋多,冬春少和年际变化大的特点。

1我国水资源地区分布“东多西少,南多北少”,其原因是我国东部为季风区,夏季风影响大,降水多,西部为非季风区,夏季风影响小甚至不受夏季风的影响,降水少,南方雨季来得早退的晚,雨季长,降水多,北方雨季来得晚退的早,雨季短,降水少。所以ACD解释错误,B解释正确。故选B

2福建上杭县降水集中在春、夏两季,在少雨季节易导致干旱,降水时间分布不均匀,解决这一问题的最佳措施是兴修水库,丰水期蓄水,枯水期放水。跨流域调水可以解决水资源空间分布不均,防治水污染可以保护水资源,人工降雨可以缓解旱情。所以A符合题意,BCD不符合题意。故选A

本题主要考查我国水资源的时空分布特点和解决水资源分布不均的措施。

【题目】 During the summer holiday, some students might have been busy with traveling, summer camps and all kinds of courses. But a special group of Chinese middle school students decided to taste the hardship of life outside school.

Twelve students in a big city sold vegetables at a local market together. Within 12 days, they made more than 1, 500 yuan.

Among them, the oldest is 21 years old, while the youngest is just 10. They are all cousins in a big family and eight of them are from rural areas.

“Compared to traveling, such social practice connects us and makes us learn how tough our parents are.” said Dalin, 18, to the City Morning Post. Dalin, a senior high graduate, and her 12yearold brother Xiaolin came up with the idea.

They learned to work hard to sell their veggies. Every morning they had to wake up at 3 o'clock. Some of them went to the farmer's market to buy vegetables. Some of them went to the local market to take up a temporary stall(临时摊位). To lower the cost, they learned to bargain(讲价) with the sellers.

At about 630 am, they began to sell vegetables. They peddled(吆喝) loudly to attract customers. After several days, they got some experience, too.

For example, it was better to put vegetables in order and bigger ones on top. When the vegetables are too heavy, they should give customers an extra plastic bag.

When they finally packed up and went home, they had a small meeting. Everyone took notes and shared their feelings.

“We are tired” said Dalin, “but we gained a lot.”
