题目内容

| B． | why does the earth go around the sun | |
| C． | why he earth goes around the sun |
分析 老师问学生们为什么地球围绕太阳转．
解答 答案：C
此题考查宾语从句，可从三个方面判断：1．陈述语序排除法，2．根据句意选择合适的引导词，3．根据时态判断．首先，排除不是陈述语序的选项B；
再根据时态：主句为一般过去时，从句需用与过去相关的时态，但宾语从句是客观真理"地球围绕太阳转"，不受主句影响，采用一般过去时，P排除A选项，故选C．
点评 此题考查宾语从句为客观事实、自然现象、科学真理时不受主句时态的限制，考生知道该特殊用法是宾语从句解题的关键．
