九年级英语Unit3-4语法专题：宾语从句专项讲解 一、定义 在复合句中，当一个句子充当宾语，这个句子叫作宾语从句。 二、关联词 1.陈述句作宾语时，宾语从句用that引导。that只起连接作用，没有实际意义，在从句中不充当任何成分，因此常省略。如： ①He can visit the capital of Kenya one day. ②My brother hopes. (合并为含有宾语从句的复合句) →My brother hopes (that) he can visit the capital of Kenya one day. ①Everyone knows. ②He shows a great talent for painting.(合并为含有宾语从句的复合句) →Everyone knows ( that )he shows a great talent for painting. 2.一般疑问句作宾语时，宾语从句用whether或if引导。whether和if意为“是否”，在从句中不充当任何成分，但不可省略。如： ①Does Tom have a collection of coins? ②Mary wants to know. (合并为含有宾语从句的复合句) →Mary wants to know whether / if Tom has a collection of coins. ①Can the physicist finish the scientific project on time？ ②I wonder.(合并为含有宾语从句的复合句) →I wonder whether / if the physicist can finish the scientific project on time. ★★whether 和 if 的用法区别： 二者都表 “是否”，多数情况可互换，但下面只能用 whether，不能用if： 1. 与 or not 连用时 例：I don’t know whether he will come or not.（√）I don’t know if he will come or not.（×） 2. 介词之后作宾语时 例：We are talking about whether we should give him a hand. 3. 后接 to do 不定式（whether to do）例：She hasn’t decided whether to accept the invitation. 4. 放在句首引导主语从句时 例：Whether they will take part in the match hasn’t been decided. 3.当特殊疑问句作宾语时，宾语从句用相应的疑问词引导。 ①The general asked me. ②When did the soldier join the army ? →The general asked me when the soldier joined the army. ①I would like to know. ②How has the biologist made such great achievements? →I would like to know how the biologist has made such great achievements. 三、语序 宾语从句要用陈述句语序(主语+谓语)。如： ①Will she go to Beijing tomorrow? ② I don't know. (合并为含有宾语从句的复合句) I don't know whether / if she will go to Beijing tomorrow. ①Could you tell me? ② When did Yuan Longping develop hybrid rice ? Could you tell me when Yuan Longping developed hybrid rice ? 四、时态 1.如果主句是一般现在时，宾语从句可根据需要使用适当的时态；(主现从任) 2.如果主句是一般过去时，宾语从句用相应的过去时态(主过从过)(一般现在时→一般过去时，现在进行时→过去进行时，一般将来时→过去将来时，现在完成时→过去完成时，一般过去时→过去完成时)。如： Andy knows (that) his wife bought a nice dress yesterday. I want to know whether / if my father will go to London next week. Jack told me sadly (that) the well-respected biologist had died in a car accident. Mary wondered whether / if Jenny was watching a movie at 8:00 p.m.yesterday. 3.当宾语从句表示名言警句、客观事实或真理时，其时态不受主句限制，始终用一般现在时。如： The teacher said (that) China lies in Asia. The geography teacher told us that the earth goes around the sun. 五、其他考点 ✅ 考点1：“疑问词 + to do” 结构（宾语从句同义简化） 适用：主句主语 和 宾语从句主语 是同一个人，宾语从句可以简化成：wh- / whether + to do（if 不能加 to do） 1. I don’t know what I should do.= I don’t know what to do. 2. Could you tell me where I can buy the stamps ?= Could you tell me where to buy the stamps? 3. She didn’t know whether she should refuse the offer.= She didn’t know whether to refuse the offer. ✅考点2：否定转移 主句主语为第一人称 I / We，谓语动词是 think, believe, suppose, expect 等，从句表达否定含义时，否定词 not 要移到主句，从句用肯定形式。 翻译：我认为…… 不……。 例：I think he is right. → 否定：I don’t think he is right.（√） 六、强化训练 基础过关：句型转换 要求：将两个简单句合并为含宾语从句的复合句，或完成同义句转换 1.
