1、Unit 3知識點總結 一、重點短語 pencil box excuse me thank you for sth. thank you for doing sth. You’re welcome. in the school library ask...for... a set of e-mail sb. e-mail sb. at+郵箱地址 call sb. call sb. at+電話號碼 What/How about sth.? What/How about doing sth.? How do you spell...?

2、 sb. must do sth. in classroom 3E 二、重點語法 1.一般疑問句 (1)一般疑問句一般翻譯為“......嗎？”需要對方用yes或no來回答。 (2)結構和答語 結構 be動詞 + 主語 +其他？ 肯定回答 Yes, 主語 + be動詞. 否定回答 No, 主語 + be動詞和not的縮寫（isn’t/aren’t,特殊：No, I’m not.). ①一般疑問句主語為this/that時，答語中主語用it. ②一般疑問句主語為those/these時，答語中主語用they. ③在肯定回答時，主語不能與be動詞縮

3、寫；否定回答時，be動詞常與not縮寫，但是am與not不能縮寫(No,I’m not.) 2. 物主代詞2：名代 (1)物主代詞的形式 人稱 第一人稱 第二人稱 第三人稱 形代 my our your your his/her/its their 名代 mine ours yours yours his/hers/its theirs 注意：兩種代詞形不同，添個s形變名，his,its不用變，my變mine要記清。 (2)用法 形代起形容詞的作用，用在名詞前，后面必須有名詞；

4、 This is my book. 名代起名詞作用，其作用相當于一個名詞，只能單獨使用，不加名詞； This book is mine. 名代=形代+名詞 This is my book. That is yours. 名代可放在句末，形代不可放句末。 注意：在使用名代時，必須有特定的語言環(huán)境，也就是要省略的名詞大家已經(jīng)知道，已經(jīng)提過。（只有上文提及了某個名詞，才會知道名代所指代的事物） (1) 順口溜:用形或用名，全憑后決定；有名則用形，無名則用名。 3. 重點句型 Is this your pencil? Yes,it is. It’s mine.

5、 Is that his blue pen? No,it isn’t. It’s hers. Are these his books？ Yes,they are. They’re his. Are those your keys? No,they aren’t. They’re Bob’s. 易錯考點 一、 用括號內(nèi)單詞的正確形式填空 1. I find a set of_____(key) in the morning. 2. He has two nice_______(watch). I have three _______(box). 3. What abo
