八年级英语下册Unit6语法讲义 宾语从句（2） 一、疑问词引导的宾语从句 1. 核心定义 当宾语从句要表达 “什么、何时、何地、如何、为什么” 等疑问含义时，用 what, when, where, how, why 等疑问词引导，而不用 that /whether/if。 2. 基本结构（挖空填写） 主句（主语 + 谓语动词）+ 疑问词 + 从句（陈述语序：主语 + 谓语 + 其他） 注意：从句必须使用陈述语序，不能用疑问语序。 答案：陈述语序 3. 例句 They couldn’t believe what they heard on the news. He asks how we can help protect the environment. I do not understand why they like computer games so much. They have not decided where they should go for the holiday. 二、宾语从句的时态问题 宾语从句的时态通常与主句时态息息相关： 1. 主句为现在时态（一般现在时、现在进行时等） 从句时态可根据实际情况，选择任何合适的时态。 例句： I can hardly believe we’re in the city centre.（从句：一般现在时） I’m sure it’ll be fantastic to see the city from the top.（从句：一般将来时） 2. 主句为过去时态（一般过去时、过去进行时等） 从句通常使用相应的过去时态（一般过去时、过去进行时、过去将来时等）。 例句： I did not know who she was.（从句：一般过去时） We thought somebody was moving about.（从句：过去进行时） 三、配套练习 （一）基础填空（用合适的疑问词填空） Do you know _____ we will hold the sports meeting (when / what) I do not understand _____ they like computer games so much.
