Answer 1

答案：1．B;2．D;3．A;4．B;5．C;
解析：

(1)	根據(jù)句子的意思及地理課上學(xué)到的知識，可知地球繞其中心旋轉(zhuǎn)的那條線叫做地軸．這是一條假想的、看不見的東西．故答案是B．
(2)	根據(jù)“The earth travels twenty-four hours around its axis once．”這個句子可直接選出正確答案．事實上，確切地說，地球自轉(zhuǎn)一周所用的時間是23時48分46秒．
(3)	答案就在“…but the sun doesn’t really do so．The turning of the earth makes us feel as if the sun were moving across the sky．”這兩句話中．選項D迷惑性較大，但是這利用由地理知識來排除．
(4)	這是表層理解題，很明顯答案在“…because everything else on the earth is turning with us”一句中．
(5)	只要理解了“When our half of the earth is facing the sun, we say it is ‘day’．When our half is away from the sun, we say it is ‘night’．”這句話中face的意思，即它在此處用作動詞(意思是“對著；面向”)，答案即可迎刃而解． 　　這是一篇介紹地球的自轉(zhuǎn)、公轉(zhuǎn)以及晝夜的交替等自然現(xiàn)象的成因的短文．借助地理學(xué)知識，是不難理解的．
