【題目】下列圖中陰影部分位于西半球、北半球的是（ ）

A. B. C. D.

【答案】C

【解析】試題分析：由經(jīng)線和緯線相互交織所構(gòu)成的網(wǎng)絡(luò)叫做經(jīng)緯網(wǎng)，利用經(jīng)緯網(wǎng)可以確定地球表面任何一個(gè)地點(diǎn)的位置．在經(jīng)緯網(wǎng)上，經(jīng)線的度數(shù)叫做經(jīng)度，若相鄰兩條經(jīng)線的經(jīng)度向東增大，就是東經(jīng)，用符號(hào)E表示，若相鄰兩條經(jīng)線的經(jīng)度向西增大，就是西經(jīng)，用符號(hào)W表示；緯線的度數(shù)叫緯度，若相鄰兩條緯線的緯度向北增大，就是北緯，用符號(hào)N表示，若相鄰兩條緯線的緯度向南增大，就是南緯，用符號(hào)S表示．

南北半球的劃分是以赤道（0°緯線）為界，赤道以北的屬北緯，用符號(hào)“N”表示，所有的北緯都在北半球，赤道以南的屬南緯，用符號(hào)“S”表示，所有的南緯都在南半球；東西半球分界線是20°W和160°E組成的經(jīng)線圈，20°W以東、160°E以西為東半球，20°W以西、160°E以東為西半球．

從經(jīng)緯網(wǎng)圖看出，A圖陰影部分位于東半球、北半球；B圖陰影部分位于西半球、南半球；C圖陰影部分位于西半球、北半球；D圖陰影部分位于西半球、南半球．

故選：A．

【題目】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.
