Tip：if/whether都可以作宾语从句的引导词，意为“是否”，但以下几种情况只能用whether： ①宾语从句在介词之后时 It depends on whether it will rain tomorrow.这取决于明天是否会下雨。 ②与or not直接连用时 I don't know whether or not they will come.我不知道他们是否会来。 ③与动词不定式连用时 I haven't decided whether to buy it.我还没决定是否买它。 ④宾语从句提前至句首时 Whether they can come here on time, we don't know.我们不知道他们能否按时来这儿。 2.语序 在宾语从句中，无论主句是陈述句还是疑问句，从句都要用陈述语序(从句本身就是陈述语序的不用变)，即“引导词＋主语＋谓语”。如： He asked Jane why she didn't come last night.他问简昨晚为什么没来。 Lucy wanted to know if I could make a cake for you.露西想知道我是否能为你做个蛋糕。 3．时态 主句 从句 例子 现在时态 根据需要使用任意时态 I don't know when he came home last night.我不知道昨晚他什么时候回家的。 过去时态 使用过去的某种相应时态 He wanted to know when his mother would be back.他想知道他的妈妈什么时候回来。 任意时态 表示客观真理或事实，用一般现在时 The teacher told the students that the earth goes around the sun.老师告诉学生们地球绕着太阳转。 Tips：(1)当主句的主语是第一人称，且谓语动词是think, believe, expect等时，若要否定宾语从句，应将主句变成否定句，即“否定转移”，但翻译成汉语时，要对从句进行否定。 I don't think they will lose the match.我认为他们不会输掉这场比赛。 (2)宾语从句的简化：当宾语从句的主语和主句的主语相同，且主句的谓语动词为remember, know, forget, learn, decide, choose, agree, ask, tell, show 等时，从句可简化为“疑问词＋动词不定式”结构。如： She has forgotten how she can ride a bike.＝She has forgotten how to ride a bike.她已经忘记了如何骑自行车。 ►►先练基础——单句训练 (　B　)1.(2023北京)—Lily, can you tell me   ⁠ during the Dragon Boat Festival this year? —Sure.We ate zongzi and watched a dragon boat race.
