Let’s listen and learn. UNIT 3 Smart Learning Section A（4a-4c） Let's review 1. 朗读并说出句意（衔接 Section A 3a-3e 阅读）： 　　I think (that) first you need to become an active learner. 2. 对比观察，找出两个句子的差别： 　　I believe you.　　｜　　I believe (that) I can fly. 3. 想一想：第二句中作宾语的是一个单词，还是一个句子？ 　　→ 由句子充当宾语 → 宾语从句（本课学习主题） Learning tip：观察 — 归纳 — 验证 先自己从例句中发现规律，再用规则回头检查自己写出的句子。 Learning Objectives In this lesson you will be able to: 1. identify the connecting words (that / if·whether / wh-words) and the object clauses in sentences; 2. master the three key points of object clauses: connecting words, word order (陈述语序) and tense; 3. use object clauses to talk about learning methods and express your opinions and questions; 4. summarize the rules by observing examples, and check your own learning with the self-check list. Let’s learn. I believe you. I believe I can fly. (that) 主 谓 宾 这两个句子有什么区别呢？ 从 句 代词 Let’s learn. I believe (that) I can fly . 宾 语 从 句 连接词 I believe (that) I can touch the sky . 宾 语 从 句 动词、介词后的句子就是宾语从句 that 无实际含义，常常可以省略 Let’s learn. the movie will be on in June. I ask I ask Will the movie be on in June? Will the movie be on in June? Will the movie be on in June? Will the movie be on in June? I ask 我问 这部电影是否在6月上映。 will be on in June. if whether the movie will be on in June. the movie will be on in June. I ask the movie will be on in June. I ask whether / if 表示“是否”，不可以省略，其后句子用陈述句语序 Let’s learn. 3 4 2 1 whether 介词后面 I’m thinking of whether Keep Run -ning will be on in May. 位于句首时 Whether it is true or not, I can’t tell. 不定式前面 They asked me whether to watch Running Man together. 与 or not 连用 I’m not sure whether it will be on in May or not. 一般情况下，if / whether 引导宾从，表示“是否”的时候，可以通用；想要不用错，选 whether 就对了。 Read the sentences. Circle the connecting words and underline the object clauses. 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. 1. that引导陈述句宾语从句，无词义，非正式书写可省略（多个宾语从句并列时，第二个 that 不能省）； 2. if /whether 引导一般疑问含义的宾语从句，表 “是否”。 宾语从句 在复合句中，由一个句子充当宾语，这个句子叫作宾语从句。 宾语从句三要素：关联词、语序、时态。 Let’s learn. 宾语从句 连接词 （引导词） 语序 时态 陈述句语序 可省略 一、关联词 引导宾语从句的常见关联词有that、if、whether、what、who、where、why和how等。 当宾语从句具有陈述意义时，用that引导。 that只起连接作用，没有实际意义，在从句中不充当成分，因此常可省略。 e.g. Mary thinks (that) the teams were just fantastic. I believe (that) reading is important for learning. Grandma still remembers (that) you love cookies. that I wonder if / whether there will be races again next year. I want to know if / whether you read English books outside class. I wonder if / whether you could help me. 当宾语从句具有一般疑问含义时，用if或whether引导，意为“是否” whether或if 在从句中不充当任何成分，但不可省略。 if / whether 只用whether，不用if引导的情况： 1) 在介词后面 e.g. I’m thinking of whether we should go to see the film. 2) 与or not直接连用 e.g. I don’t know whether or not they can get there on time. 一般来说，在宾语从句中if与whether可以互换使用。但有时，两者不能互换。 I don’t know whether / if she will go to Beijing tomorrow. The boy didn’t believe that his cat died. Do you know if / whether Lucy will go to Beijing to have a meeting tomorrow? 二、语序 无论主句是陈述句还是疑问句，也无论主从句间是什么引导词，宾语从句一律用陈述语序：引导词+主语+谓语+其他。 I know (that) Jack is a hard-working student. I know (that) he will take the exam. Jenny knows the man was flying a kite at that time. 宾语从句的时态一般受主句时态的影响。 如果主句是一般现在时或一般将来时，that, whether/ if 引导的宾语从句可根据需要使用适当的时态。 三、时态 Linda didn’t say if her aunt was still with them. Dad told me that the sun rises in the east. Teresa told her son that leaves turn yellow in autumn. 当主句是一般过去时，从句要用相应的过去时态。 当从句表示的是客观真理或自然现象等时，一般不受主句时态的限制，用一般现在时。 4b Complete the sentences with that or whether / if. 1.
