【題目】讀地球繞太陽(yáng)公轉(zhuǎn)示意圖(如圖1),回答下列問(wèn)題.
(1)地球公轉(zhuǎn)的方向 , 周期 .
(2)地球公轉(zhuǎn)位置在B點(diǎn)時(shí),太陽(yáng)直射在(23.5°N,23.5°S),
北半球的季節(jié)是 .
(3)地球上南北半球的季節(jié) .
(4)圖2為荊門市某學(xué)校的王玲同學(xué)在不同時(shí)間里她的身影長(zhǎng)短變化情況示意圖.假如王玲的身高不變,請(qǐng)比較判斷:如果是在同一天,則更接近正午的是圖(填甲或乙);如果是在不同季節(jié)的正午時(shí)刻,則更接近冬至日的是圖(填甲或乙).
【答案】
(1)自西向東;一年
(2)23.5°N;夏季
(3)相反
(4)乙;甲
【解析】讀圖可知,(1)地球繞太陽(yáng)不停的旋轉(zhuǎn)叫地球的公轉(zhuǎn),地球公轉(zhuǎn)的方向自西向東的,周期是一年.(2)地球公轉(zhuǎn)位置在B點(diǎn)時(shí),為北半球的夏至日,日期為6月22日前后,太陽(yáng)直射在北回歸線上,即23.5°N緯線上,此時(shí)北半球?yàn)橄募荆?)地球上南北半球的季節(jié)是相反的,當(dāng)北半球?yàn)橄募緯r(shí),南半球?yàn)槎荆?)由于地球自轉(zhuǎn),在同一天,正午的太陽(yáng)高度角最大,影子應(yīng)最短,從圖中看出乙圖影子短,應(yīng)在正午;由于地球公轉(zhuǎn),在不同季節(jié)的正午時(shí)刻,冬至日太陽(yáng)直射了南回歸線,北半球太陽(yáng)高度角最小,影子最長(zhǎng),從圖中看出甲圖影子長(zhǎng),應(yīng)更接近冬至日.所以答案是:(1)自西向東;一年;(2)23.5°N;夏季;(3)相反;(4)乙;甲.

【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.
