题目内容
【题目】Peter knew .
A. whether he has finished reading the book
B. why the boy had so many questions
C. there were 12 months in a year
D. when will they leave for Paris
【答案】B
【解析】
考查宾语从句,句意:皮特知道了为什么这个男孩有如此多的问题.根据Peter knew可知,考查宾语从句,宾语从句中一般为陈述语序,当主句是一般过去时态,宾语从句应该用过去的某一时态,所以选项AD时态不对;C选项叙述的是客观真理,应该用一般现在时态,故选B.
