【名师点睛】本题是对宾语从句中连词的考查。对于宾语从句的连词的选择，首先确定连词的词义，然后根据句意判断出正确的连词，本句的句意很明显，确定为＂是否＂。 【拓展延伸】
在复合句中，如果由一个句子充当宾语，这个句子叫作宾语从句。引导宾语从句的常见关联词有that, if/whether, what, who, where, why和how等，本单元主要学习that和if/whether引导的宾语从句。 一、that引导的宾语从句 1. 关联词
当宾语从句是陈述句时，用that引导，that在口语或非正式文体中常省略。 2. 时态
（1）如果主句为一般现在时，从句可选择任意适当的时态。 （2）如果主句是一般过去时，从句一般要用过去的某种时态。
（3）当宾语从句是表达客观事实或自然规律的句子时，即主句使用过去时态，宾语从句仍用一般现在时态。 二、if/whether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whether引导宾语从句，if/whether意为＂是否＂。一般情况下，if和whether可互换，在口语中多用if，而在以下几种情况下，只能用whether： 1. 当or not直接跟在关联词后时，只能用whether。. 2. 在动词不定式之前只能用whether。
3. 在介词后通常用whether。
【易错提醒】
关联词that在下列情况下不可省略： （1）当宾语从句的主语是that时。 （2）当宾语从句前有插入语时。
（3）当宾语从句是双宾语中的直接宾语时。
