图是某地海岸地区的等高线(单位:米)示意图,比例尺为1:50000,图中每一方格的边长为2厘米。读图回答下列各题。

一方格的边长为2厘米。读图回答下列各题。

小题1:与本区域沿海的其他位置相比,渔港M的区位优势是

A.风浪小

B.腹地广

C.航道深

D.不封冻小题2:若在甲处建一储运仓库,需将所在小山头沿50米等高线铲平,平整后的土地面积约为

A.0.1km2

B.0.3 km2

C.1 km2

D.2 km2

答案

小题1:A

小题2:B

题目分析:

小题1:与本区域沿海的其他位置相比,渔港M的腹地与是否封冻和其他地方差别不大,因为该图是大比例尺,实际范围不大,纬度差异极小气温差别也就极小;没有等深线不知道M地航道深浅,但有小溪汇入倒有可能淤积;渔港M处于海湾,受风浪影响小。故选A。

小题2:图中比例尺为1:50000,也就是1厘米代表0.5km, 每一方格的边长为2厘米,即1km, 面积1 km2。甲处50米等高线围成的面积约为一个方格的三分之一。故选B。

Directions: Read the following passage. Answer the questions according to the information given in the

passage.

                                                                My First Long Run

     Two weeks ago, I had a quarrel with my husband. After he had driven off in anger, I realized that I wasn't

going to feel any better just sitting there. Feeling abandoned and guilty, I put on my gym shoes to get some

fresh air.

     Our driveway has a slope (斜坡) that is easier just to jog down if you are lazy, taking advantage of gravity.

Instead of stopping at the end of the lope, I decided to see if I could just jog to the end of the street. I had tried

a few moths ago and failed miserably. Since that first attempt I had been jogging regularly and was significantly

fitter, but still very lazy. However this time around I managed to reach the stop sign with ease and I figured I

would go a little further.

     After about one kilometer, however, I noticed that my upper body was tense. To make the movement easier

I had to relax my body, and tried to take deep breaths of fresh air.

     I kept giving myself the excuse to stop. No one would be disappointed. No one would even know. But I

didn't stop. I wanted to keep going harder, better, faster, stronger. To my great surprise, I ran 4.9 km in 31

minutes. When I got back, I had tears in my eyes. I did some thing I thought I could never do.

     It was the first run of my life. Since then, I have improved my stride (步幅) and time. After every run I feel

fitter, happier and motivated to keep progressing. I love the runner's high. I normally jog because I want to look

good. I want to run because it makes me feel good.
