ifwhether引导的宾语从句
当从句部分是一般疑问句或选择疑问句时,常用if或w hether引导宾语从句,ifwhether意为"是否"。
说明对陈述的事物不明确或不清楚。常 用在see,ask,say,learn,tell,wonder,doubt,find out,be uncertain

使用if 或 whether 两个词来表达不定性,两者都算标准。

形式(客观事实和真理 除外),这样A选项也不符合题意,答案为B。
5. A 【解析】句意:——你能告诉我这里附近是否有一个书店吗?——是的,当然可以。根据Could you please
tell me可知,本题是考查宾语从句,宾语从句中一般为陈述语序。选项B、C是 疑问语序,所以排除
