问题 综合

(10分)下图所示是我国部分地区气温年较差分布图,读图完成下列问题。

(1)气温年较差最大值出现在_______(省级行政区)。(2分)

(2)归纳图示地区气温年较差的分布规律。(2分)

(3)图中P地的气温年较差大约是多少?与附近同纬度地区相比,其年较差有何特点?并分析其原因。(6分)

答案

(1)黑龙江          

(2)气温年较差由低纬(南)向高纬(北)增大

(3)39℃左右。  与附近同纬度地区相比,P地气温年较差较小,其原因是该处地势较高(大兴安岭)

题目分析:

第(1)题,本题等值线是气温年较差分布图,图中等值线从低纬向高纬增加,由图可知气温年较差最大值出现在黑龙江。

第(2)题,受纬度影响,纬度越高,气温年较差越大,故气温年较差的分布规律是气温年较差由低纬(南)向高纬(北)增大。

第(3)题,根据图中数值变化趋势,可以判断出图中P地的气温年较差数值介于38到40之间,与附近同纬度地区相比,P地年较差较小,其原因是该处地势较高,位于大兴安岭地区。

点评:本题难度较小,解答本题的关键是根据经纬度对区域进行准确定位,然后根据数值变化及区域自然地理环境特征具体问题具体分析即可作答。

Boris was a teacher. He taught science at a high school. For he needed some books for his lessons, he went to a bookshop to buy some. After he put them in his car in a quiet street, he went to buy some other things at other shops. When he came back to his car, one window was open and the books were gone. Boris drove home sadly.

That night he called a newspaper. The next day people read an advertisement in the newspaper:

Books: Have you got any old books? I buy old and modern books. Open all day on Saturdays. Boris 82 West Road.

And then he went to the police station with the Wednesday newspaper at once.

The first weekend, when Boris was staying at home, his first visitor came at 8:30 in the morning. Boris took him to the kitchen. At about ten o’clock another man arrived. He had a bag under his arm.

As soon as he saw Boris, he asked, “Are you Boris?”

“Yes, I am,” Boris said. “What can I do for you?”

“Look! I have got some good books here. You buy books, don’t you?”

“Yes. Bring them in. Let me have a look at them.”

Soon the books were taken in and showed on the dinning-table. “Sir, come out now,” Boris called. “And take the list with you.”

A policeman appeared in the dinning-room. He read the names on the books, and then read the names on the list in his hand. He found that they were the same.

“Come with me, sir,” the policeman said to the man.
