题目内容

【题目】古代描写我国河流的诗句很多，其中苏轼的《念奴娇·赤壁怀古》中“大江东去，浪淘尽，千古风流人物”，就是对长江的描写。

据此回答下列各题。

【1】导致长江这种流向的原因是（）

A.地势西高东低，呈阶梯状分布B.地形多种多样，山区面积小

C.地势南高北低，呈阶梯状分布D.气候类型多样，降水总量丰富

【2】对我国河流的叙述，不正确的是（）

A.外流河的水文特征深受季风气候影响

B.内流河大部分属于季节性河流

C.长江自古以来就享有“黄金水道”的盛誉

D.黄河是我国第二大河

【答案】

【1】A

【2】D

【解析】

中国外流区面积610多万平方千米，约占全国陆地总面积的64%．内流区面积约占全国陆地总面积的36%．中国绝大多数河流分布在外流区，外流河年径流总量占全国的95%以上，内流河年径流总量不足5%。

【1】地势的特点决定河流的流向，河流总是由高处向低处流，由于中国地势西高东低，呈阶梯状分布，所以长江水自西向东流．故选：A。

【2】A、我国外流河的水文特征深受季风气候的影响．随着雨带由南向北推移，河流水量骤增，水位上涨，形成汛期．故A不符合题意；

B、我国外流河多分布在西北内陆．这里降水稀少，气候干旱，河水主要来自高山冰雪融水．夏季，随着冰雪融化，内流河水量增多；夏季过后，河流水量逐渐减少，甚至断流．所以，内流河大部分属于季节性河流．故B不符合题意；

C、长江中下游水流平稳，江面开阔，不少河段江面宽度超过10千米，航运价值高．长江地处亚热带季风气候区，降水丰富、无结冰期，四季通航，自古以来就享有“黄金水道”的盛誉，故C不符合题意；

D、黄河是我国第二长河，也是世界著名大河之一．它源自巴颜喀拉山，流经青海、四川等9省区，注入渤海，全长5464千米，流域面积75.24万平方千米．故D符合题意。

故选：D

本题考查我国的地势特点及影响，属于基础题，理解简单即可。

【题目】 When I was in high school, I worked parttime helping Dad sell fruits and vegetables at a market. One day, as I was preparing the fruits, a little boy came by with his mom and sister. He was about eight years old, and the girl, five or six. They were looking at the fruits in front of me. I heard the kids say to their mom(in French)，“They're good！” I knew it was French, because I can speak and understand it.

Then I noticed how the mom was picking the fruits. At first I thought she was really looking at the fruits because she was facing them, but then I noticed how much she had to feel and smell each one as she picked them out. And she often asked her son if it looked okay, but looked way above where his face was. Putting what I saw together, I was sure she was blind.

Both of the kids continued to help their mom pick out the fruits. The son made sure the fruits were not obviously bad, and the daughter handed them to her mom. The woman then felt each one and smiled, and the daughter would put them into their basket. The kids were smiling while helping their mom pick the fruits out.

Their smile and gentle manner moved me in a way that never happened before. It was so beautiful to see such young kids so willingly help. Most kids that age would be picking out candies or toys in a store for themselves, instead of helping their mom pick out fruits, as the two kids did.

It was great to witness the moment, but not so great because I didn't tell the mom how beautiful her children were in their language. This is what I regret to this day.

C.his mom and sisterD.his mom and brother

【4】The writer was moved because________.

A.the mother was brave to face her problemsB.the kids were polite and kind to each other

C.the mother was careful in picking out thingsD.the kids were so willing to help their mother

【题目】属于内流河的是

A.淮河B.塔里木河C.长江D.黄河

【题目】我国最大的淡水湖、咸水湖分别是（　　）

A.洞庭湖、青海湖B.洪泽湖、鄱阳湖
