(2)地球公转位置在B点时,太阳直射在(23.5°N,23.5°S),
北半球的季节是
(3)地球上南北半球的季节
(4)图2为荆门市某学校的王玲同学在不同时间里她的身影长短变化情况示意图.假如王玲的身高不变,请比较判断:如果是在同一天,则更接近正午的是图(填甲或乙);如果是在不同季节的正午时刻,则更接近冬至日的是图(填甲或乙).

【答案】
(1)自西向东;一年
(2)23.5°N;夏季
(3)相反
(4)乙;甲
【解析】读图可知,(1)地球绕太阳不停的旋转叫地球的公转,地球公转的方向自西向东的,周期是一年.(2)地球公转位置在B点时,为北半球的夏至日,日期为6月22日前后,太阳直射在北回归线上,即23.5°N纬线上,此时北半球为夏季.(3)地球上南北半球的季节是相反的,当北半球为夏季时,南半球为冬季.(4)由于地球自转,在同一天,正午的太阳高度角最大,影子应最短,从图中看出乙图影子短,应在正午;由于地球公转,在不同季节的正午时刻,冬至日太阳直射了南回归线,北半球太阳高度角最小,影子最长,从图中看出甲图影子长,应更接近冬至日.所以答案是:(1)自西向东;一年;(2)23.5°N;夏季;(3)相反;(4)乙;甲.

【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.
