【题目】下列图中阴影部分位于西半球、北半球的是( )

A. B. C. D.

【答案】C

【解析】试题分析:由经线和纬线相互交织所构成的网络叫做经纬网,利用经纬网可以确定地球表面任何一个地点的位置.在经纬网上,经线的度数叫做经度,若相邻两条经线的经度向东增大,就是东经,用符号E表示,若相邻两条经线的经度向西增大,就是西经,用符号W表示;纬线的度数叫纬度,若相邻两条纬线的纬度向北增大,就是北纬,用符号N表示,若相邻两条纬线的纬度向南增大,就是南纬,用符号S表示.

南北半球的划分是以赤道(纬线)为界,赤道以北的属北纬,用符号“N”表示,所有的北纬都在北半球,赤道以南的属南纬,用符号“S”表示,所有的南纬都在南半球;东西半球分界线是20°W160°E组成的经线圈,20°W以东、160°E以西为东半球,20°W以西、160°E以东为西半球.

从经纬网图看出,A图阴影部分位于东半球、北半球;B图阴影部分位于西半球、南半球;C图阴影部分位于西半球、北半球;D图阴影部分位于西半球、南半球.

故选:A

【题目】David walked down the street. All he wanted to do was to play basketball with Jim. But his mother told him to return his sister's books to the library on his way to Jim's house.

In his eyes, books and summertime just don't go together. He thought he had read a lot during the school year. And he had never set foot inside a public library. Today he'd just drop the books off in the outside return box, but it was locked. He had to go inside to return them.

David walked inside the building a few minutes before closing time. He put the books into the return box. After a quick drink of water and a short stop in the toilet, he'd be on his way to meet Jim. He walked out of the toilet. The library lights were turned off. He was locked—in a library!

David tried to use the telephone, but he couldn't find one. As the sun began to set, he searched for a light and found a little one on a desk. He used a pencil to write a note on a big piece of paper. It read, “I'm locked inside. Please call for help.” He put it on the front door. Surely, someone passing by would see it. He then turned his attention to the library itself.

He was surprised to discover that this place was not so bad. Rows and rows of books! When he saw a book about Michael Jordan on the desk, he picked it up. He opened the book and began to read. He felt that being locked in the library didn't seem to be such a terrible thing.
