初三英語重點難點解析 [作者] 周振行/陸偉平 [內(nèi)容] Unit 5 The Accident 本單元要求學(xué)生更好地掌握過去進(jìn)行時態(tài)的各種句式,并能活學(xué)活用;掌握 用"had better"等來提出建 議的句式,通過做18課的練習(xí)2之后,使學(xué)生 逐漸了解如何進(jìn)行課文縮寫。可以模訪第19課的"ACCIDENT REPORT"進(jìn)行練習(xí)。 一、提出建議并能作出恰當(dāng)?shù)幕卮?/p> 在第二冊第6單元已經(jīng)學(xué)到過用"shall","Let's"和"why not"來提 出建議,并作簡略回答。 如: ①-Shall we go at ten? -Good idea! ②-Let's go at ten? -OK! ③-Why not go at ten?-All right. 這一單元里,主要學(xué)習(xí)有關(guān)"had better"的用法。"had better+動詞原 形"表示"最好做某事",用 來向別人提出建議,其形式可以縮寫為"d better"。如: ①You'd better do your homework now. ②We'd better go to school. "had better"的否定形式為"had better not…"如:You'd better not watch TVnow. 二、學(xué)習(xí)過去進(jìn)行時的各種句式 在前一單元里,已經(jīng)學(xué)習(xí)了過去進(jìn)行時的構(gòu)成和用法,這一單元著重學(xué)習(xí)它 的否定句式、一般疑問句式及 在從句中的用法。 1.過去進(jìn)行時的否定式在助動詞"be(was或were)"后面加上"not" 即可。如: I was not washing clothes last night. 2.過去進(jìn)行時的一般疑問句式為:助動詞"was或were"在句首。如: —Was Tom writing a letter at seven yesterday? —Yes,he was.(No,he wasn't.) 3.在含"when"和"while"(當(dāng)……時)引導(dǎo)的時間狀語從句的復(fù)合句中, 常有過去進(jìn)行時,表示一個 動作在過去某一時刻或一段時間內(nèi)正在進(jìn)行或發(fā)生。 這一過去進(jìn)行時的動作可以出現(xiàn)在主句,也可以出現(xiàn)在從 句中,但要注意的是, 用該時態(tài)的動詞常常是一個持續(xù)性動詞。如: ①Someone knocked at the door when I was cook-ing ② While we were talking,my mother came in. ③ The twins were sweeping the floor when their mother returned. 另外,含"when"的復(fù)合句中,主句用過去進(jìn)行時,從句用一般過去時的情 況下,常包含有"意外"之概 念,如前例③。 三、重點、難點詞組和句子的分析 1. You look tired today. (2.17)(你看上去很累。) 該句中的"look"意為"看起來",是系動詞,而在這種系動詞后面常用形 容詞作表語如look young/hap y/old/…等,另外,"look"也可用作實義動詞, 并且有許多相關(guān)詞組,如:look at …(看…)look like… (看起來像……), look the same(看起來很相像),look for…(尋找……),look after…(照 料/照看 ……)等等。當(dāng)然,不能再用形容詞來作表語或修飾它,如果要修飾, 只能用副詞。如: Please look after your watch carefull. 2. A woman saw it happen when she was walking past.(L17) 表示感覺的動詞如"see,hear,watch"等以及一些其它動詞如"make, let"等,后接不定式作其賓語補(bǔ) 足語時,該不定式前不帶"to"。如: ①I'm tired.Let me have a short rest. ②Do you often hear Tom sing this song? ③I saw him go out.(我看到他出去了。) 另外,"see,hear,watch"等還可后接現(xiàn)在分詞作其賓語補(bǔ)足語。如: I heard someone laughing. (我聽到有人在笑。) 3.The children were leaving school on Tues-day when they saw a truck. (2.18) 該句中有二點需要注意: ①"were leaving"是過去進(jìn)行時的形式表示過去將來的動作,即"正要離 開……"。在英語中,個別動 詞如:"leave,go, come,start"等,它們的 進(jìn)行時形式可以表示一個最近按計劃或安排要進(jìn)行的動作。如 : Are you going home next week? ②"leave school表示"(學(xué)生)離校;畢業(yè)";中間不加冠詞。又如;go to school/come to school( 上學(xué))。類似的表達(dá)法如: in hospita1(住院),leave hospital/come out of hospita1(出院)。注意比較下 句中冠詞的區(qū)別; His mother often goes to ____the school to seeher son at ______ school. 4.He did not see the bag until it was too late: (L18) "not…until…" 是"直到 ……才……"如: ①. She won.'t go away until you promise, to help her. ②. I didn't go home until I finished cleaning the classroom. 5. It's really nice of you. (L18) 該句相當(dāng)于"It's very kind of you."(你真好。) 6. He told her about the accident. (L18) "tell sb. about/of sth." 意為: 初三英語重點難點解析>"告訴某有關(guān)某事或 跟某人講述某事"。如: Please tell me about your family. 另外, "tell sb. sth./tell sth. to sb." "告訴某人某事", "tell sb. todo sth. ":"叫某 人做某事"。如: ① I told him my name. ② My grandfarther often told us stories when we were children. ③ She told the happy news to everyone. ④ Tell him to wait for me at the school gate. 7. Please hurry up! (L18) Miss zhao hurried off to look after the man.(L18) "hurry up"; "趕 快";"hurry off"; "匆匆離去"如: ① Hurry up, or you'll be late for school. ② Tom finished the work and hurried off. 8. Give short answers to these questions.(L20) 一般地,在表示"……的"時,可以用以下四種形式: ① 's: 通常在表有生命的事物后,以"s"結(jié)尾的復(fù)數(shù)名詞只加"'"即 可。如: Tom's coat. Teachers' Day, Children's Day等。 另外,一些無生命的如表示"時間、城鎮(zhèn)"等的名詞后,也可加“s'"。如: Tomorrow's meeting, the city's streets, etc. ② of:通常是與無生命事物的名詞相連。如: Parts of China, a photo of my family ③ to:一些表達(dá)法已成為習(xí)慣,有時我們可理解為配套的事物。如:the key to thedoor, answers to t he questions. ④形容詞性物主代詞置于名詞前。如:my book. Unit 6. In the library 一、語法:現(xiàn)在完成時(一) 1、構(gòu)成:助動詞have/has+動詞的過去分詞 2、主要用法:(一)動作發(fā)生在過去,對現(xiàn)在留有影響,可以與到現(xiàn)在為 止的時間狀語these days, up to now, recently, in the last two years連用,也可以與一些表示強(qiáng)調(diào) 的副詞aleady,yet,just, before, ever…eg.連用:I have (already) seen the film. Have you ever been there (before )? 注意:A、動詞過去分詞的變化有兩種,一種與過去式的規(guī)則變化一樣(即 在動詞后加ed);另一種為不 規(guī)則變化,需要熟讀熟記。規(guī)則變化如下: 1)動詞原形加ed,如:work--worked 2)以e結(jié)尾加d,如:like--liked 3)以輔音字母加y結(jié)尾的動詞,變y為i,再加ed,如:worry--worried 4)以重讀閉音節(jié)結(jié)尾,詞尾只有一個輔音字母的動詞,雙寫這個輔音字母 再加ed,如:stop--stopped B.現(xiàn)在完成時與一般過去時的區(qū)別在于:一般過去時只單純表示過去的動 作和狀態(tài),與現(xiàn)在無任何聯(lián)系 ,時間狀語常為:yesterday, last week,3days ago, in 1990; 現(xiàn)在完成時則強(qiáng)調(diào)動作與現(xiàn)在的聯(lián)系、影響 和結(jié)果。 eg. Have you seen the film? Yes, I have. When did you see it? I saw it last week. 二、詞匯與句型 have got=have 1.I think I've got one. { has got=has 2.Here you are.這是一種倒裝語序,常用在口語中。 Can I use yourpen for a while? eg.{ Certainly.Here you are. 類似的還有:There goes the bell. Here comes the bus. 3.Have you seen it anywhere? anywhere常用于疑問句和否定句;some where表示某個地方,常用于肯定 句;no where=not anywhere, e verywhene, 是處處、到處的意思。 eg. I can't find my pen anywhere. He has borrowed some money somewhere. I have looked for my lost bike everywhere. Where likes them to borrow them. { Nowhere. 4.She also likes them to borrow them. borrow : 借來,借進(jìn),與form連用。 詞組:borrow sth.from sb. { lend:借來,與to連用。詞組: {lend sb.sth.lend sth.to sb. eg. Whom have you borrowed the bike from? Can you lend me your bike? wifh sb. 5.She is very strict, be strict{ in sth. 初三英語重點難點解析 eg. She is strict in her job. Our teacher is strict with us. 6.Please be more careful from now on. from now on:從現(xiàn)在起,還有from tomorrow on, from then on, from next weekon. 7.I have never lost a book before. ago與before都是副詞,前者用 于過去時,后者用于現(xiàn)在完成時 ,泛指以前。 eg. I lost my pen three days ago. I haven't seen such a good film before. 8.We must both thank Lucy !注意both,all,each作同位語的位置: 1.放在be動詞后;2.放在行 為動詞前;3.放在助動詞與謂語動詞中: eg. We are all students. They have both gone there. We each have an English book. 9.You must always return your library book on time. return表示give back, 故后面不再跟back. on a train 10.{ by train不能加冠詞或任何修飾詞,類似的有:in a car,on my bike, by trainby bus,by bike,by air… 11.……,you must pay for it. pay for sth."付…的錢,賠償…" eg. I paid two yuan for the book.
