【题目】日全食指在地球上的部分地点太阳光被月亮全部遮住的天文现象。2016年3月9日,印度尼西亚出现日全食天象奇观。据此回答下列各题。

【1】日全食的过程中,涉及到的相关天体所构成的天体系统有

【2】在涉及的天体系统中,较低级别天体系统的中心天体是

A.月球 B.太阳 C.地球 D.金星

【答案】

【1】C

【2】C

【解析】

试题分析:

【1】本题考查天体系统的层次。日食出现时太阳月球地球处于同一直线上,月球处于太阳和地球之间遮挡了太阳光,从而出现了日食现象。该现象涉及到的天体有地球、月球、太阳。天体系统的层次为:最高一级为总星系(即目前所知的宇宙范围),第二级为银河系和河外星系(河外星系简称星系),银河系又向下分成第三级的太阳系及其他恒星系,太阳系向下分成最低一级的地月系和其他行星系。该现象包含太阳系和地月系,。所以本题选择C选项。

【2】由上题可知,地月系的天体系统级别较低,地月系的中心天体为地球,故答案选C项。

I once had the unpleasant experience of someone breaking his promise to me. Last month, everyone in my class had to gather at school 5 6:30 AM for our 6 (graduate) trip. My friend Ben asked me 7 (meet) him at McDonald’s at six, but he never showed up. I was 8 (depress) that when I called him, he told me he was already at school. I 9 (rush) straight there, but all my classmates still blamed me for delaying the trip. After that, I ended my friendship with Ben because I don’t need 10 (friend) who can’t keep their word.
