【正文】 ut。 語(yǔ)法——的一般現(xiàn)在時(shí)的用法。難點(diǎn)：表示時(shí)間的介詞以及靈活運(yùn)用一般現(xiàn)在時(shí)。三、知能提升 （一）重點(diǎn)單詞 ［單詞學(xué)習(xí)］◎ want【用法】want作及物動(dòng)詞時(shí)，意為“想要”，其后可接名詞、動(dòng)詞不定式等?！纠洹?. I want some green tea. 2. I want to speak good English.【考查點(diǎn)】考查want to do 和want sb. to do ?！疽族e(cuò)點(diǎn)】沒(méi)有識(shí)記want后要接to do作賓語(yǔ)或賓語(yǔ)補(bǔ)足語(yǔ)。 15.【考題鏈接】The old man wants you make noise in the room. A. to B. for C. don’t to D. not to解題思路：本題考查動(dòng)詞不定式的否定形式。want sb. not to do “希望某人不要做某事”，不定式的否定要在to前加not，故選D。本題的句意是“這位老人希望你不要在房間里吵鬧?！?◎ although【用法】although=though是連詞，引導(dǎo)讓步狀語(yǔ)從句，意思是“雖然……，但是……”。在英語(yǔ)里，句中如果用了although或though就不能再用but?！纠洹?. Although/Though he is very old, he is quite strong. 2. He works hard although/though he is in bad health.【考查點(diǎn)】考查連詞although和but只能用其中的一個(gè)【易錯(cuò)點(diǎn)】受“雖然……，但是……”這種漢語(yǔ)句式的影響，既用了although又用了but。【考題鏈接】— the soldiers are very tired, they keep on working.—They are great. We must learn from them.A. Because。 / B. Though。 / C. Because。 so D. Though。 but 解題思路：although意為“盡管，雖然”，引導(dǎo)讓步狀語(yǔ)從句，可放在主句前，也可放在主句后，當(dāng)although引導(dǎo)從句時(shí)，其后不能再與but連用；同樣，若句中有轉(zhuǎn)折連詞but時(shí)，although也不能出現(xiàn)。具有相同用法的還有because和so不能同時(shí)連用（“因?yàn)椤?，所以……”）?！?表示時(shí)間的介詞：at, in, on【用法】at可以表示某一時(shí)刻，如：at nine, at noon, at breakfast等； in表示一段時(shí)間，常用于年、月、季節(jié)之前，如：in spring, in 2004； on表示在某一天，常與日期、星期或某天的上午、下午、晚上連用，如：on my birthday, on the morning of May 1st；【例句】1. I go to school at 7 o’clock every day. 2. The new term begins in September. 3. The old man died on a cold morning. 【考查點(diǎn)】在具體的語(yǔ)境中選用正確的介詞【易錯(cuò)點(diǎn)】on the morning of May 1st中的on錯(cuò)用為in【考題鏈接】—Look. Your bus is ing.—That’s No. 15. Ours is No. 5. It es 9: 15 Monday.A. at, in B. at, on C. in, on D. on, in解題思路：at, on, in三個(gè)介詞都可以用在時(shí)間名詞之前，但用法不同。at用于具體時(shí)間點(diǎn)之前；on用于具體某一天或某天的上午、下午、晚上；in用于月、季、年前?！?should【用法】should是情態(tài)動(dòng)詞，意為“應(yīng)當(dāng)”，用來(lái)向別人提出建議，以勸導(dǎo)別人。其后接動(dòng)詞原形。 【例句】1. You should brush your teeth before you go to bed. 2. You shouldn’t drink and drive. 16.【考查點(diǎn)】情態(tài)動(dòng)詞的基本用法【考題鏈接】1. You should eat some vegetables. （改為否定句）You vegetables. 答案：shouldn’t eat any解題思路：should的否定形式應(yīng)在should后加not，后面跟動(dòng)詞原形，some要變?yōu)閍ny。2. He should go out this Sunday. （改為一般疑問(wèn)句） he out this Sunday? 答案：Should, go解題思路：含有情態(tài)動(dòng)詞的句子變?yōu)橐话阋蓡?wèn)句時(shí)，把情態(tài)動(dòng)詞直接放在句首就可以了。［即學(xué)即練］1. The doctor wants me milk for breakfast every day. A. get B. to drink C. to buy D. have2. Mr Li wants me (join) the swimming club. （用動(dòng)詞的適當(dāng)形式填空）3. they are brothers , they don’t look like each other . A. Because B. Although C. When D. As 4. New York and Washington D. C. are good places to visit May or October.A. from B. at C. in D. on 5.—When did this accident happen?—It happened six o’clock the afternoon of last Monday.A. at。 in B. in。 on C. about。 at D. at。 on 6. He should lots of water. A. drinks B. drink C. not drinks D. didn’t drink （二）重點(diǎn)短語(yǔ)［短語(yǔ)學(xué)習(xí)］◎ how about【用法】how about用于詢(xún)問(wèn)情況、征求意見(jiàn)或提出建議，后接名詞、代詞或動(dòng)詞ing形式。 【例句】1. You are quite good at English. How about your maths? 2. How about going for a walk after supper? 【考查點(diǎn)】how about的用法【考題鏈接】My parents are both fine. How about ? A. you B. your C. yours D. her解題思路：how about用來(lái)詢(xún)問(wèn)情況。所以本題應(yīng)該問(wèn)的是你的父母或她的父母的健康狀況，故只能選yours=your parents。句意為“我的父母身體都很好，你的父母呢？”◎ think about【用法】think about 表示“考慮，思考”，about是介詞，后接名詞、代詞和動(dòng)詞ing形式作賓語(yǔ)?！纠洹?. Tom is thinking about a difficult problem. 2. Mr Green is thinking about having a meeting. 【考查點(diǎn)】辨析：think about與think of, think over的區(qū)別?！疽族e(cuò)點(diǎn)】沒(méi)有識(shí)記相關(guān)短語(yǔ)的用法?！究碱}鏈接】Can you the past? A. think of B. think about C. think over D. think 解題思路：think of意為“想起”；think about 和think over都有“思考”的意思，而think只是單純的想。句意為“你能想起過(guò)去的事嗎？” 17.（三）重點(diǎn)語(yǔ)法◎ 頻率副詞 【知識(shí)講解】頻率副詞表示動(dòng)作發(fā)生的頻率，通常用于一般現(xiàn)在時(shí)。常用的頻率副詞按照頻率發(fā)生的高低分別是always usually often sometimes hardly ever never。頻率副詞一般用于be動(dòng)詞、助動(dòng)詞、情態(tài)動(dòng)詞之后，行為動(dòng)詞之前。但sometimes一詞非常靈活，既可以放在句首也可以放在句中或句末?！纠洹縄 always have some milk for my breakfast.He usually gets up at 6:30 in the morning. Lucy is never late for school.Sometimes Jim goes to the movies on Friday evening. 【考查點(diǎn)】根據(jù)語(yǔ)境使用正確的頻率副詞【考題鏈接】We play sports in the school on weekdays, you know, we don’t have enough time. A. often B. usually C. hardly ever 解題思路：A意為“經(jīng)常”，B意為“通常”，C意為“幾乎不”。由句中“我們沒(méi)有足夠的時(shí)間”可判斷，在學(xué)校里我們“幾乎不”做運(yùn)動(dòng)。He is late for school. He is not a good student. A. often B. never C. not D. hardly ever 解題思路：由句中“他不是一個(gè)好學(xué)生”可知他上學(xué)“經(jīng)?！边t到。often表示“經(jīng)常，常?！薄＃奂磳W(xué)即練］1. He helps us to learn English. We all like him.A. sometimes B. usually C. hardly ever D. never2. I’m too busy. I watch TV.A. usually B. sometimes C. hardly ever D. often◎一般現(xiàn)在時(shí)【知識(shí)講解】概念：一般現(xiàn)在時(shí)表示一段時(shí)間內(nèi)經(jīng)常發(fā)生的動(dòng)作或存在的狀態(tài)。結(jié)構(gòu)：當(dāng)主語(yǔ)是第一人稱(chēng)、第二人稱(chēng)或第三人稱(chēng)復(fù)數(shù)形式時(shí)，謂語(yǔ)動(dòng)詞用動(dòng)詞原形。當(dāng)主語(yǔ)是第三人稱(chēng)單數(shù)形式時(shí)，謂語(yǔ)動(dòng)詞用第三人稱(chēng)單數(shù)形式，即在動(dòng)詞詞尾加s或es。規(guī)則變化：1）一般在動(dòng)詞詞尾加s。2）以字母s, x, sh, ch或o結(jié)尾的動(dòng)詞，在詞尾加es。3）以輔音字母加y結(jié)尾的動(dòng)詞，先變y為i再加es。不規(guī)則變化：be－is, have－h(huán)as用法：1）表示經(jīng)常性、習(xí)慣性或永久性的動(dòng)作，常與always, usually, often, every day, every week等時(shí)間狀語(yǔ)連用。He is often late for class.

We often (play) in the playground. 解題思路：題中有often，表示“經(jīng)常做某事”，故用一般現(xiàn)在時(shí)。主語(yǔ)是we，所以動(dòng)詞用原形。2. Mike (read) English every day? 答案：Does。 read 解題思路：此句是一個(gè)一般疑問(wèn)句，主語(yǔ)是第三人稱(chēng)單數(shù)，所以第一個(gè)空填助動(dòng)詞Does，助動(dòng)詞后應(yīng)用動(dòng)詞原形。［即學(xué)即練］1. —Can your father drive?—Yes, and he usually to work.
