Observe and explore the semantic features, sentence structures and declarative word order rules of object clauses introduced by that, if/whether and question words, and summarize the selection of conjunctions, tense agreement and usage differences of the three types of object clauses. 2. Use the three types of object clauses correctly in real contexts of talking about teenage growth troubles, asking for help and giving advice, so as to consolidate and internalize the core usage of object clauses. 3. Write a help-seeking passage by correctly using object clauses introduced by that, if/whether and question words to describe their own growth puzzles, improve the comprehensive application ability of grammar, and deepen the understanding of active communication and solving growth problems. Review 翻译下列Reading中的句子 1.我想知道我们是否真正理解彼此！ 2.我就是不知道如何减少手机使用时间。 3.我真的希望你能给我一些建议。 I wonder if we understand each other at all! I just don’t know how to cut back on phone time. I really hope you can offer me some advice. 想一想：这三个句子是什么类型？ Object clauses 宾语从句 A Object clauses introduced by if or whether Read the text below and pay attention to the object clauses introduced by if or whether. Amy often argues with her best friend about silly small things. She wonders if this is normal, so she talks to her mum about it. Amy asks her mum whether she has any advice. Her mum tells her to talk to her friend about the situation. Amy wants to improve their friendship, but she isn’t sure if talking about it will help. We use if or whether to introduce an object clause that expresses a yes-no question. Such an object clause often follows verbs such as ask, see, wonder and find out. The word order in the clause should be the same as that in a statement. 我们用 if 或 whether 引导表达是否问题的宾语从句。这类宾语从句常跟在 ask, see, wonder, find out 等动词后。从句的语序应和 __________ 一致。 陈述句 She wonders if this is normal. She wonders if is this normal. √ × We often use whether instead of if in formal situations. The teacher wanted to know whether the students were under a lot of stress. 在正式场合中，我们通常用 __________ 而不用 __________。 whether if A1 Amy is writing a diary entry about her studies. Complete it below using that or if/whether. I just had my History exam, and I don’t know (1) ____________ I passed it. I know (2) ____________ I tried my best, but I’m not sure (3) ____________ that’s good enough. I’ll have to wait to find out. I really hope (4) ____________ I do well at school this year. That’s why I work so hard every day. I’m not sure (5) ____________ I need to do more. I wonder (6) ____________ it would improve my grades or just make me more stressed. From the bottom of my heart, I just want to succeed and feel proud of myself. if/whether that if/whether that if/whether if/whether A2 Talk with your partner about your learning problems, using object clauses introduced by if or whether. A: Hi, how’s your study going these days? I’m having a hard time with my math. I wonder if I can catch up with others before the midterm exam. B: Oh, I feel the same. I’m not sure whether I can keep up with the teacher’s speed in class. Sometimes I get lost halfway. A: Me too! I often doubt if I’ve chosen the right way to study. Maybe I should change my study plan. B: That’s a good idea. I’m also thinking about asking the teacher for help. I wonder whether she will have time to talk to me after class. A: I hope so. I’m also worried about my English listening. I don’t know if I can improve it in a short time. B: Don’t worry. Maybe we can practice listening together every evening. I’m not sure if my listening skills are good, but two heads are better than one. A: That sounds great! I really hope we can make progress together. if 或 whether 引导的宾语从句 1. if 和 whether 在作“是否”理解时，引导宾语从句时常放在动词 know, ask, care, wonder, find out等之后，此时从句部分的语义相当于一个一般疑问句。 I want to know if/whether he is our new teacher.我想知道他是不是我们的新老师。 拓展提升 2. if 和 whether 都可以引导宾语从句，表示“是否”，在口语或间接引语中两者可以互换使用。如： I wonder if/whether I can get some advice from you.我想知道是不是能从你那里得到一些建议。 Ask him whether/if he can come.问一问他能不能来。 3. 用 whether，而不用 if 的情况： ① 作介词的宾语时，用whether，而不用if。 I am interested in whether he’ll go to have a picnic.我对他是否去野餐很感兴趣。 ② whether引导的从句可移到主句之前而if不能。 Whether this is true or not, I am not sure.我不确定这是不是真的。 ③ 后面紧接or not时，只用whether。 We didn’t know whether or not she had come.我们不知道她是不是已经来了。 ④ 用if会引起歧义时， 只用whether。 Please let me know whether you like it.请告诉我你是否喜欢它。 4. 宾语从句语序必须是陈述语序，即“连接词＋主语＋谓语＋其他成分”。 “Did Mary clean the classroom yesterday?” Mr Wu is asking. Mr Wu is asking if/whether Mary cleaned the classroom yesterday. 胡老师正在询问昨天玛丽是否打扫教室了。 5. 宾语从句中的人称代词要符合逻辑，有时需进行合理变化。 She wonders, “Can I keep that book for one more week?” She wonders if/whether she can keep that book for one more week. 她想知道那本书她能不能再借一个星期。 B Object clauses introduced by question words Read the text below and pay attention to the object clauses introduced by question words. Teenagers often have problems with their parents. They do not always understand why their parents have so many rules. Although this is a common problem, many teenagers do not know what they should do. They are not sure how they can have an honest dialogue with their parents. They do not know who they can ask for advice either. Tip: Whom is an object pronoun. In a very formal style, whom is sometimes used instead of who. 提示：whom 是人称代词宾格，在非常正式的文体中，有时用 whom 代替 who。 Work out the rule! We use a question word to introduce an object clause that expresses a wh-question. The word order in the clause introduced by a question word should be ______________. (different from,the same as) that in a wh-question. the same as 我们用 __________ 引导表达特殊疑问句的宾语从句。由疑问词引导的宾语从句，语序应和 __________ 一致。 疑问词 陈述句 B1 The Class 1, Grade 9 students are talking about their problems.

Rewrite his questions by using object clauses introduced by if/whether or a question word. 1.Why did I argue with my friends yesterday? Can I explain ? 2.Can Millie help me get along well with my friends? I wonder . 3.Where can I find useful articles on friendship? I want to know ________________________________________.

Dear Mr Friend, My name is Li Hua. I have a problem and I need your advice. I know that my parents are strict with me. They don’t allow me to play basketball after school. I love sports very much, but I don’t know how I can make them understand my feelings. I also wonder whether I should give up my hobby to focus more on my schoolwork. I am under a lot of stress these days. Could you tell me what I should do to solve my problem? I hope you can give me some useful advice. Best wishes, Li Hua 连接代词和连接副词引导的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述语序。常见的连接代词有who, whom, whose, which和what，在宾语从句中充当主语、宾语、定语或表语；常见的连接副词有when, where, why和how，在宾语从句中充当状语。 拓展提升 (1) 宾语从句的时态：① 如果主句的时态是一般现在时，宾语从句可以根据实际需要使用各种时态；如果主句是一般过去时，从句则只能用相应的过去时态(一般过去时、过去进行时、过去完成时等)。② 如果宾语从句所陈述的是客观真理、自然现象、定理、谚语、名人名言等，则用一般现在时。 (2) 当宾语从句由连接副词或连接代词引导时，有时可以改为由“连接副词/代词＋动词不定式”构成的不定式短语，使宾语从句转化为简单句，但前提是主句的主语与从句的主语一致。 当堂检测 一、单项选择 1.No one has ever doubted 　　　　 he is an honest and hard-working young man.
