问题 问答题

读下面我国两大河流示意图,回答下列问题:

(1)图中字母A所代表的支流是______,字母C所代表的海洋是______.

(2)黄河上、中游的分界点B  是______.

(3)黄河的______ (上游、中游、下游)河段形成“地上河”,治理该河段应采取的主要措施是______;黄河不会发生凌汛现象的是______(上游、中游、下游).

(4)黄河是我国的“母亲河”但历史上水患严重.下列措施中,你认为治理黄河有效的是______

①加固下游河堤②修建分洪蓄洪工程③造林种草,加强水土保持④修建水利工程

A.①②③④,B.①②③,C.①②④,D.②③④

答案

(1)黄河发源于青海省,向东注于渤海,主要的支流是汾河渭河,图中的A代表汾河,C代表渤海.

(2)黄河上中下游的分界点是内蒙古的河口和河南孟津,图中的B是上中的分界点河口.

(3)由于黄河下游泥沙淤积形成为“地上河”,导致黄河下游流域面积比较狭窄,几乎无支流汇入;治理黄河在不同的河段依据情况有不同的措施:中游保持水土、下游加固黄河大堤;黄河在由南向北流的河段容易出现凌汛,中游河段正好是由北向南流,所以该河段不会出现凌汛.

(4)黄河是我国的“母亲河”但历史上水患严重,治理黄河的关键是治沙,治沙过程中,应加强中游黄土高原的水土保持工作,造林种草,并结合打坝淤地、修梯田,同时修建水库,使防沙和防洪并举.

故答案为:

(1)汾河;渤海;

(2)河口;

(3)下游;加固黄河大堤;中游; 

(4)A.

完形填空
There was once a group of young people searching everywhere for happiness but what they got was only annoyance, grief and misery.
So they       Socrates for advice on where happiness      . But       giving any answers, Socrates asked them to help with building a       first. The group of guys had to       the task, laying aside their own business of seeking happiness. It took them a long time to cut down a tall tree, gouging out (挖空) the center. Through painstaking effort, they made a canoe out of the tree. They launched the canoe into a river, and then       together in it, singing with      .
Socrates asked, “My children, do you have happiness now?” They answered in chorus: “We       be happier!” Socrates      , “That’s it!       you are too busy pursuing something to notice anything bitter, happiness will occur.”
From the story I got to know that happiness      hides behind every tiny thing that you are involved in, and that you may only get pleasure through       work and creativity.
We may have to       pain in our daily life and in the process of       happiness. Sometimes we tend to look for happiness in       things, like a new car, clothes, etc. True long term happiness, however, comes from within our       and spirit. So why not turn suffering into       life, and       tears into the light in your heart? Only in this way can we make it through and find true happiness.
So my dear friends, just remember happiness is a state of mind and a matter of      , and I       you all a life of happiness.
