初三英語重點難點解析
Unit 5 The Accident
本單元要求學生更好地掌握過去進行時態(tài)的各種句式，并能活學活用；掌握用“had better”等來提出建 議的句式，通過做18課的練習2之后，使學生逐漸了解如何進行課文縮寫�？梢阅ＴL第19課的“ACCIDENT
REPORT”進行練習。
一、提出建議并能作出恰當?shù)幕卮?
在第二冊第6單元已經(jīng)學到過用“shall”，“Let’s”和“why not”來提出建議，并作簡略回答。
如：
�、�-Shall we go at ten?
-Good idea!
�、�-Let's go at ten?
-OK!
�、�-Why not go at ten?-All right.
這一單元里，主要學習有關“had better”的用法�！癶ad 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.
�、赪e'd better go to school.
“had better”的否定形式為“had better not…”如：You'd better not watch TVnow.
二、學習過去進行時的各種句式
在前一單元里，已經(jīng)學習了過去進行時的構(gòu)成和用法，這一單元著重學習它的否定句式、一般疑問句式及 在從句中的用法。
1.過去進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……時)引導的時間狀語從句的復合句中，常有過去進行時，表示一個 動作在過去某一時刻或一段時間內(nèi)正在進行或發(fā)生。這一過去進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：
�、賁omeone knocked at the door when I was cook-ing
② While we were talking，my mother came in.
�、� The twins were sweeping the floor when their mother returned.
另外，含“when”的復合句中，主句用過去進行時，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“l(fā)ook”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，“l(fā)ook”也可用作實義動詞，并且有許多相關詞組，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 足語時，該不定式前不帶“to”。如：
①I’m tired.Let me have a short rest.
�、贒o you often hear Tom sing this song?
�、跧 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：
�、佟皐ere leaving”是過去進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：“l(fā)eave，go, come，start”等，它們的進行時形式可以表示一個最近按計劃或安排要進行的動作。如 ：
Are you going home next week?
�、凇發(fā)eave school表示“(學生)離校；畢業(yè)”；中間不加冠詞。又如；go to school/come to school( 上學)。類似的表達法如： 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:
�、�. She won.'t go away until you promise, to help her.
�、�. I didn't go home until I finished cleaning the classroom.
5. It's really nice of you. (L18)
該句相當于“It's very kind of you.”（你真好。）
6. He told her about the accident. (L18) “tell sb. about/of sth.”意為：“告訴某有關某事或 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：
�、� I told him my name.
② My grandfarther often told us stories when we were children.
�、� She told the happy news to everyone.
�、� 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：
�、� 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:一些表達法已成為習慣，有時我們可理解為配套的事物。如：the key to thedoor, answers to t he questions.
�、苄稳菰~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
