I think that moon cakes are delicious! PART 01 宾语从句 宾语从句是用一个完整的句子来充当主句中的宾语成分。它的构成形式是：主句+引导词+宾语从句。 宾语从句 I know you . I know who you are. 主语 谓语 宾语 简单句 主语 谓语 宾 语 从 句 连接词 从句主语 从句谓语 主 句 复合句 看区别 常见引导宾语从句的引导词1- that 引导陈述句作宾语的从句，本身无实际意义，在口语或非正式文体中常可省略。 She thinks (that) he is right. 她认为他是对的。 I know (that) they will come tomorrow. 我知道他们明天会来。 He said that he was very tired after a long day's work. 他说经过一天长时间的工作后他很累。 he is afraid that she will be late for the meeting. 她担心自己开会会迟到。 常见引导宾语从句的引导词2 连接代词（what, which, who, whom, whose） 引导特殊疑问句作宾语的从句，本身有具体意义（“什么”“哪一个”“谁” 等），在从句中充当主语、宾语、定语等成分，不可省略。 Do you know what he said? 你知道他说了什么吗？—— what 在从句中作宾语 Can you tell me who broke the window? 你能告诉我谁打破了窗户吗？—— who 在从句中作主语 She asked me whose book this is. 她问我这是谁的书。—— whose 在从句中作定语 常见引导宾语从句的引导词3 连接副词（when, where, why, how） 引导特殊疑问句作宾语的从句，本身表示时间、地点、原因、方式等，在从句中充当状语，不可省略。 He wants to know when the meeting will start. 他想知道会议什么时候开始。—— when 表时间 Please tell me where you live. 请告诉我你住在哪里。—— where 表地点 I don’t understand why he refused the invitation. 我不明白他为什么拒绝邀请。—— why 表原因 由从属连词 that 引导的宾语从句 2. 由从属连词 whether, if 引导的宾语从句 本单元的重点是… 1.由从属连词 that 引导的宾语从句 当宾语从句的主句是一般现在时，从句的时态可以根据实际情况灵活选择，不受主句时态限制，使用任何合适的时态即可。 I think he gets up early every morning. 我认为他每天早上起得很早。 He says he will finish the work in three days. 他说他会在三天内完成这项工作。 The teacher finds that Tom lost his key yesterday. 老师发现汤姆昨天丢了钥匙。 She tells me that she has learned English for five years. 她告诉我她已经学了五年英语了。 若主句是一般过去时，宾语从句的时态要与主句保持一致，需使用过去的某种对应时态（如一般过去时、过去进行时、过去将来时、过去完成时等）。 He said that he visited his grandparents last weekend. 他说他上周末去看望了祖父母。 I knew that my dad was working in the garden at that time. 我知道那时爸爸正在花园里干活。 The teacher said that we would have a test the following week. 老师说我们第二周要考试。 He found that he had left his umbrella in the classroom. 他发现自己把伞落在教室里了。 如果宾语从句表达的是客观真理或科学事实，无论主句是什么时态，从句的谓语动词都要用一般现在时。 The teacher says that the sun rises in the east. 老师说太阳从东方升起。 He told us that light travels faster than sound. 他告诉我们光比声音传播得快。 Scientists have proved that gravity exists everywhere. 科学家已经证实重力无处不在。 She was explaining that plants need sunlight to grow. 她当时正在解释植物需要阳光才能生长。 2.由从属连词 whether, if 引导的宾语从句 “if” 和 “whether” 都可以表示 “是否”，用它们引导的宾语从句，通常是因为说话人对陈述的内容不太确定、存有疑问。 这类引导词常搭配一些带有疑问或不确定含义的词语使用，比如 “ask（问）”“wonder（想知道）”“can you tell me（你能告诉我）”“could you tell me（你能告诉我）” 等。 需要注意的是，由 “if/whether” 引导的宾语从句，句子意思是完整的，不缺少主语、宾语、状语等成分。 与 ask 搭配 She asked me if I would go to the concert with her. 她问我是否愿意和她一起去听音乐会。 与 wonder 搭配 I wonder if he remembers our first meeting. 我想知道他是否记得我们的第一次见面。 其他常用动词搭配 He didn’t know if he should accept the invitation. 他不知道是否应该接受邀请。 与 can/could you tell me 搭配 Could you tell me if there is a bank near here? 你能告诉我这附近是否有银行吗？ 在大多数情况下 whether 和 if 可以互换，但在句首、与 or not 连用或接不定式时，通常用 whether Whether he will come, I’m not sure. She asked whether I liked coffee or tea. tips 宾语 从句 小结 引导词 that+陈述句 if／whether+一般疑问句 特殊疑问词+特殊疑问句 时 态 主句为一般现在时,从句根据语境定时态 主句为一般过去时 ,从句 一般过去时 过去将来时 过去进行时 过去完成时 语 序 宾语从句的语序都为陈述句语序 客观真理时态不变 主现从随意 主过从也过 真理永不变 PART 02 感叹句 在初中英语中，感叹句指的是用来抒发强烈情感的句子，这些情感涵盖了喜悦、气愤、悲伤、恐惧等多种类型。这类句子在结构上，一般会由 What 或 How 来引导。 感叹句的基本结构 What + a/an + 形容词 + 可数名词单数 +（主语 + 谓语）！ 例：What a beautiful flower (it is)！多美的一朵花啊！ 注：可数名词单数前需加 a/an（根据形容词首字母发音判断），括号内的主语和谓语可省略。 What + 形容词 + 可数名词复数 +（主语 + 谓语）！ 例：What clever children (they are)！ 多聪明的孩子啊！ What + 形容词 + 不可数名词 +（主语 + 谓语）！ 例：What heavy rain (it is)！多大的雨啊！ 由 What 引 导的感叹句 How 修饰的是形容词、副词或动词，基本结构为： How + 形容词 +（主语 + 谓语）！ 例：How happy (they are)！他们多开心啊！ How + 副词 +（主语 + 谓语）！ 例：How quickly (he runs)！他跑得真快啊！ How + 主语 + 谓语！（此时 How 修饰动词，强调动作的程度） 例：How time flies！时间过得真快啊！ 由 how 引 导的感叹句 感叹句的基本结构 What型 感叹句 What an attractive city!
