答案

小题1:珠江流域降水丰富(淮河流域降水少) (1分)

小题2:淮河流域的水库库容与径流总量的比值高 (1分)

小题3:台风影响 1分  冬季流域内降水少,径流量小 ( 2分)

小题4:夏季降水集中,多暴雨 ( 1分)

小题5:13  ( 1分)

小题6:广州此时气温适宜,降水少、不受台风影响,经济发达,城市、城际交通便利,观众、志愿者众多等 (3分 言之成理可酌情给分)

小题1:河流流量取决于流域的面积和流域内的降水量。淮河流域面积约为珠江流域的3/5,但珠江流域降水丰富,淮河流域降水少。所以径流总量却不足珠江的1/5。

小题2:根据材料分析:淮河流域的水库库容与径流总量的比值高,所以淮河流域水资源利用率远高于珠江流域。

小题3:珠江中下游地区夏秋季节台风影响,多突发性暴雨洪水。冬季冬季流域内降水少,径流量小,河口处常受海水入侵的威胁,形成咸潮。 

小题4:淮河流域夏季降水集中,多暴雨,所以7、8月份多洪水。

小题5:根据材料分析:耕地面积之比为480:1200;径流量之比是622:3338。所以淮河受农业污染的程度约为珠江的13倍。

小题6:广州为亚热带季风气候区,雨季时间长;11月份广州此时气温适宜,降水少、不受台风影响,经济发达,城市、城际交通便利,观众、志愿者众多等。

A lawyer and a young lady were sitting next to each other on a long flight. The lawyer asked if she would like to play a fun game. The lady just wanted to take a nap, so she politely refused.

The lawyer explained that the game was actually very easy. He explained “I ask you a question, and if you don’t know the answer, you pay me, and vice versa(反之亦然).” Again, the lady politely refused and tried to get some sleep.

The lawyer added eagerly, “Okay, if you don’t know the answer, you pay me $5, and if I don’t know the answer, I will pay you $50!” Considering that there would be no end to this suffering unless she played, the lady agreed.

The lawyer asked the first question, “What is the distance from the earth to the moon?” The young lady didn't say a word, pulled out five dollars from her purse and handed it to the lawyer.

Now, it was the lady’s turn. She asked the lawyer, “What goes up a hill with three legs, and comes down with four?” The lawyer was greatly puzzled. He took out his computer and searched all of his references. He searched the Net and sent e-mails to all of his friends, but it was all to no avail. After over an hour, he woke up the lady and handed her $50. The lady politely took the money and turned away to get back to sleep.

The lawyer, very puzzled now, woke the lady up again and asked, “Well, what on earth is the answer?” Without a word, the lady reached into her purse, handed the lawyer another $5 and went back to sleep.
