Unit 3 Smart Learning Section A Grammar Focus (4a-4c) 01 02 03 能识别宾语从句结构，分清that、if/whether引导词的用法差异，圈画从句、引导词不出错。 能结合华罗庚自学案例，用宾语从句简单表达对学习方法的看法，尝试口头造句分享个人学习疑问与观点。 能在单句、短文语境中正确选用that/if/whether填空，准确补全语篇。 Learning objectives ① I need a pen. ② John helped her. ③ Children stopped talking. ④ I do not want to cry. ⑤ I am interested in Chinese festival. 名词 代词 V-ing形式 动词的 to do形式 宾语表示动作行为的对象，常跟在及物动词或介词之后。 试着找出下列句子中的宾语。 Lead in 名词短语 动词后跟宾语 介词后跟宾语 Can you find the objects? Can you find the objects? I believe (that) I can fly. 主语 谓语 关联词 宾语 He knew (that) he should study hard. Lead in 主语 谓语 关联词 宾语 置于动词、介词等词性后面，在句子中起宾语作用的从句叫做宾语从句。 4 What are types of object clauses? I find that taking notes in class helps me review knowledge better. 1. 主语 + 及物动词 + 宾语从句 动宾 We are talking about how we can memorize English words more quickly. 2. 主语 + 动词 + 介词 + 宾语从句 介宾 We are glad that group discussion can help us understand hard knowledge points. 3. 主语 + be + 形容词 + 宾语从句 形宾 所以大名鼎鼎的宾语从句： 其实就是一个 “跟屁虫” 跟在动词，介词，形容词后~ Look and say Presentation 4a Circle the connecting words（关联词）and underline the object clauses（宾语从句）. I believe (that) reading is important for learning. I think (that) the best way is to do maths problems. Peter finds (that) he can connect physics with something in real life. I wonder if / whether you could help me. I want to know if / whether you read English books outside class. 引导宾语从句的关联词有that, if, whether， that在非正式文体中可以省略，whether/if不可省略 在复合句中，由一个句子充当宾语，这个句子叫做宾语从句 宾语从句学习要点。 时态 01 02 03 宾语从句三要素： 关联词 语序 Let’s think 7 根据关联词的不同，宾语从句可分为以下三种： 1. 由that引导的宾语从句； 2. 由if/whether引导的宾语从句； 3. 由疑问词引导的宾语从句： what, which, who, whom, whose (疑问代词) when, where, how, why (疑问副词) Presentation 宾语从句关联词that 陈述一个 _____ I believe 陈述一个 _____ I think 陈述一个 _____ Peter finds 信念 观点 发现 1.我认为使用闪卡是记忆新单词的好方法。 I think (that) using flashcards is a good way to remember new words. 2. 我希望我能成为一名主动学习者。 I hope (that) I can become an active learner. 当及物动词后接一个__________作宾语时，该从句通常由______引导。that_______实际意义，不充当从句成分，通常可以______。 陈述句 that 省略 没有 宾语从句结构I: 主语+谓语动词+that+宾从(肯定句、否定句) Presentation that在以下情况中不可省略： I know that that is Lisa’s textbook. ①当宾语从句的主语是that 时。 The manager said, at the meeting, that he wanted to thank all of us. ②当主句与that 引导的宾语从句之间有插入语时。 The teacher told the students (that) they should hand in their homework on time and that they would have a test the next day. ③当主句谓语动词后接两个或两个以上宾语从句时，除第一个从句外，其他从句的that不可省略。 I will never tell anyone that you have ever been there. ④当that宾语从句是双宾语中的直接宾语时。 ⑤当宾语从句中含有其它从句（如if/when引导的从句）时，that不能够省略。 I’m afraid that if you miss the Spring Festival family dinner, you will feel really lonely. I believe (that) he will not do such a silly thing. = I don't believe (that) he will do such a silly thing.  当主句的主语是第一人称 I 或we，且谓语动词是think, believe, suppose, guess等时，如果宾语从句要表达否定含义，一般将否定词not转移到主句的谓语中。即“否定转移”。  观察两个句子的区别 我相信他不会做如此愚蠢的事。 当主句表达“想知道、不确定一件事是不是真的”，就要用_____ 或__________引导宾语从句，意为“是否”，______省略。 if whether I want to know about it. Could you help me?  合并为一句→ I want to know. Do you read English books outside class？合并为一句→ I wonder if / whether you could help me. I want to know if / whether you read English books outside class. 不可 宾语从句关联词if/whether 宾语从句结构II:主语+谓语动词+ whether/if+宾从(由于if/whether连接的句子在语义上是一般疑问句或选择疑问句，要注意把从句改为陈述句语序) 陈述句的语序，即“主语在前，谓语在后”的顺序. What are the differences between “ if ” and “ whether ” ? • I don’t know if / whether I can improve my English fast. • It depends on whether I practise speaking every day. • I wonder whether I can memorize more words or not. • He asked whether to finish the homework before ten. Whether you read English books outside class ,I want to know. 1. 当 if 和 whether 用在谓语动词后面表示“是否”时, 一般情况下两者_________。 2. 下列四种情形，只能用whether： 当宾语从句置于______之后时，引导词只能用whether。 当宾语从句中含有________时，只能用whether。 当从句以“whether + _______________”的结构出现时，引导词只能用whether。 当whether引导的从句置于_____起强调作用时，引导词只能用whether。 介词 不定式 (to do) 句首 or not 可互换 Exercise I don't know ___________ he will come to our English party.
