Section A How do we learn? Grammar Focus UNIT 3 Smart Learning 01 02 03 能够在"Smart Learning"主题语境中观察、理解和归纳 that、if 与 whether 引导的宾语从句的结构与功能,掌握宾语从句的语序(陈述语序)及主从句时态呼应规则; 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。 准确区分 if 与 whether 的使用条件,并能根据语境恰当选择;在复杂语境中灵活处理宾语从句的时态呼应(尤其是主句为过去时的情况),做到表达准确、得体、连贯,形成对宾语从句独立而有逻辑的运用能力。 Learning objectives ① I need a pen. ② John helped her. ③ Children stopped talking. ④ I do not want to cry. ⑤ He knew (that) he should study hard. 名词 代词 V-ing形式 动词的 to do形式 句子 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。 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。 、 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. 4a Read the sentences. Circle the connecting words and underline the object clauses. 1. that 引导陈述句宾语从句,无词义,口语 / 非正式书写可省略; 2. if /whether 引导一般疑问含义的宾语从句,表 “是否”。 、 that, if, whether, what, who,where, why和how等 主现从随意 主过从随过 事实真理永不变 宾语从句用陈述句语序,即“主语+谓语” 宾语从句 主语+谓语 + 连接词 (引导词) + 宾语从句 宾语从句三要素 引导词 时态 语序 根据引导词的不同,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) 、 (1) 由that引导的宾语从句:表示陈述一件事实,主句谓语动词表确定,非疑问; 宾语从句结构I: 主语+谓语动词+that+宾从(肯定句、否定句) I believe that reading is important for learning. 主语 谓语 宾语从句(肯定句) Bill thinks that the books were not interesting to watch. 宾语从句(否定句) 主语 谓语 宾语从句的连接词 that在句中无任何意义,不充当句子成分,常省略。 I believe (that) he will not do such a silly thing. = I don't believe (that) he will do such a silly thing.  *think, believe, suppose, guess等动词作主句的谓语,且主句的主语是第一人称 I 或we时,若后面的宾语从句表示否定概念,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。 由并列连词连接的两个或多个that引导的宾语从句,只有第一个从句中的that 可以省去,其余并列宾语从句中的that都要保留。 She said (that) she missed her family and that she would go home soon. it作形式宾语代替that引导的宾语从句时,that不能省略。 They took it for sure that we would help them. 形式宾语 真正的宾语 that在宾语从句中的省略与保留 、 (2)由if / whether引导的宾语从句:whether与if通常可以互换,且常跟在ask、want to know、wonder、doubt、unsure、uncertain等之后引导宾语从句,引出两个或以上的可能性之一; 宾语从句结构II: 主语+谓语动词+ whether/if+宾从(一般疑问句,陈述语序) whether/if在从句中也不充当任何成分,不可省略 由于if和whether连接的句子在语义上是一般疑问句或选择疑问句,因此要注意把从句语序改为陈述句语序。 、 主语 谓语 宾语从句(一般疑问句,陈述语序) I wonder if/whether you could help me. 主语 谓语 宾语从句(一般疑问句,陈述语序) I want to know if / whether you read English books outside class. 主语 谓语 宾语从句(一般疑问句,陈述语序) I wonder if/whether it will rain tomorrow. 陈述句的语序,即“主语在前,谓语在后”的顺序. 一般情况下,if / whether 引导宾语从句,表示“是否”的时候,可以通用;想要不用错,选 whether 就对了。 ① I wonder ... ② Is the Water Festival really fun? 试将下面两句话合并为一句: 宾语从句 谓语动词 I wonder if/whether if/whether引导的宾语从句 陈述语序 the Water Festival is really fun. 只用 whether 不用 if 的情况 在whether ... or not的固定搭配中; I can't say whether or not he will come on time. 在介词后,只能用whether; I'm interested in whether he joins the army. 宾语从句置于句首时,只能用whether; Whether he will come, I'm not sure. 在动词不定式前只能用whether。 Tomorrow the teacher will tell us whether to have a test. 、 Exercise. I don't know ___________ he will come to our English party. She asks ___________ you have finished your homework. We are wondering ___________ to take part in the speech competition. Could you tell me ___________ it will rain tomorrow or not? He didn't know ___________ his friend liked this new learning method. It all depends on ___________ we can get enough time to practice. I want to know ___________ your brother enjoys reading English stories. They haven't decided ___________ they will go abroad for study. if / whether if / whether if / whether if / whether if / whether whether whether whether 小试牛刀 、 宾语从句的时态 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 若主句是一般过去时,从句则用过去相关的时态 主过从随过 Did the train leave? She didn’t know. →She didn’t know if / whether the train had left. 、 宾语从句的时态 事实真理永不变 1.The teacher told us that the earth moves around the sun. 2.He said to me light travels faster than sound. 老师告诉我们地球绕着太阳转 他对我说光比声音传播的更快。 一般过去时 一般现在时 一般过去时 一般现在时 从句是客观真理是用一般现在时态 、 宾语从句的时态 ►Danny says that he will learn English. ►Do you know where he came from? ►Please tell me how I can get to the bus station. 比较主句和从句的时态变化 一般现在时 一般将来时 一般现在时 一般过去时 一般现在时 一般现在时 若主句是一般现在时,从句用任何所需时态。 主现从随意 、 宾语从句的语序 注意观察下面句子的变化 Does he like sports? ( Do you know…) Will they play basketball after school? ( He asks…) 一般疑问句 陈述句 一般疑问句 陈述句 Do you know (whether) he likes sports? He asks (whether) they will play basketball after school. 宾语从句都是运用陈述句的语序,即“主语在前,谓语在后”的顺序 、 that(陈述句) if/whether(一般疑问句) who; whom; whose; which; what; when; where; why; how(特殊疑问句) 主句为一般现在时, 从句可以是任何时态 主句为一般过去时, 从句进行相应的过去变化 客观真理,自然现象等不变 陈述语序 连接词 时态 语序 宾语从句三要素 【总结】 微软中国 (微) - 4b Complete the sentences with that or whether / if.

Could you tell me __________ this sentence is correct in English? whether that that if / whether if / whether 一看意思:先看“从句有没有疑问 / 选择含义”。有则用 whether/if,无则用that。 二看搭配:从句末尾有or not/在介词后/从句位于句首/后跟 to do 不定式,只能用whether。 三看动词:表示“陈述、相信、认为、知道”的动词(think, believe, know等),多用that; 表示“疑问、想知道、不确定、询问”的动词(wonder, ask, don't know等),多用whether/if。 、 Who is this person? What do you think of him? I think/believe/wonder that he... 、 华罗庚(1910—1985),江苏常州金坛人,祖籍江苏丹阳,著名数学家。他是多国科学院院士,曾任中国科学院数学与系统科学研究院原所长、全国政协副主席等职。 华罗庚早年毕业后进入清华大学工作,曾赴英国剑桥大学访问学习,先后任教于清华大学、美国多所知名高校。1950年,他毅然放弃国外优厚待遇回国,途中写下《致中国全体留美学生的公开信》,归国后主持清华数学系工作,牵头建设国内数学研究体系,长期投身我国数学科研与教育事业。 他深耕解析数论、矩阵几何学等多个数学领域,攻克多项国际数学难题,改良诸多经典研究成果。其创立的华氏定理、华氏不等式、华—王方法等成果,被国际数学界认可并以其姓氏命名,极大提升了中国数学的国际地位。 Complete the passage with the correct sentence parts.
