6、少在飯館吃飯。2. 英語中表次數(shù)的用法OnCe 一次，twice 兩次，three times 三次，four times 四次 我們能夠看出表示次數(shù)的詞，除了“一次，兩次”特殊外，后面的次數(shù)都是“基 數(shù)詞+times”構(gòu)成。另外同學(xué)們還要記住以下詞組：OnCe （twice） a day/ week/ month/ year 每天（周/月/I ） 一（兩）次3. alL most, some, no的用法及差異。all “所有的，全體的”Ail StUdentS do homework after SChOOLLaSt night, I COOked all the VegetableS i

9、e.g.HOW many apples do you have?HOW Inany StlIdentS are there in your class?如果名詞是不可數(shù)名詞，要用'How much +不可數(shù)名詞”。e.g.HOW much milk do you drink each time?HOW much Water do We need every day?【課文解析3a】but m Pretty healthy I exercise every day, USUany When I COme home from SChOOl And my eating habits are

Of course, I IOVejUnk food, too. but I try to eat it OnIy OnCe a week, oh, and I SleeP nine hours every night SO you see, I IOOk after my health And my healthy IifeSt

11、yIe helps me get good grade GOOd food and exercise help me to StUdy better1. Pretty表示"十分”作副詞用，我們以前學(xué)過quite和Very也有這種意臥 其中它們的水準(zhǔn)由淺入深為quitepretty-*very. e.g.He is quite SeriOUS It SOUndS Pretty good Nina Can Sing EngliSh SOngS Very WelL2 I exercise every day, USUany When I COme home from SChOOl 我每天鍛

13、er my health."所以你看，我很在意我的健康”。IOOk after意為"照顧、照看”。e.g.Can you IOOk after my baby When I leave?PleaSe IOOk after your OWn bags carefully.Iook還能夠和很多詞搭配，但意思不一樣。(1 ) Iook at U看，認(rèn)真地看”。e.g.PIeaSe IOOk at the blackboard SOme PeOPle are IOOking at the notice (2 ) IOOk for "尋找"o e.g.OId He

16、 twice a week.他每周看兩次電視?！居蒊lOVV Often談起】我們已經(jīng)學(xué)習(xí)了 always, usually, often, SometimeS, never等表示時間頻度的副 詞。這些詞通常用來說明在一段時間內(nèi)做某事的多少或某種狀態(tài)存有的次數(shù)的多 少。例如：We USUally get UP at half PaSt six. 我們通常六點半起床。SOmetimeS he goes to See his grandpa On weekends.周末,他有時候去看望爺爺。但是，在日常生活中，我們不可能總是用陳述句來表達自己的或他人的一些行 動，或者事物所存有的狀態(tài)。我們還要向?qū)?/p>

17、方提出一些問題，請求對方回答。在 這種情況下，我們還要用礙問句。請看下面兒組對話：1 一HOW Often do you Play football?I USUany Play football after SChOOl 2 一HOW Often does Mary go to the concert?She Often goes to it On SatUrday evening3 一HOW Often does my daughter take the medicine?Three times a day.不知大家是否注意到，我們針對上面所說的頻度副詞和表示“在某段時間內(nèi)某 種動作的次數(shù)”

18、的狀語提問時,都要用how Ofteno換句話說，如果要回答111 how Often提問的句子，我們通常要用頻度副詞或諸如every day, each week, OnCe a week, twice a day, four times a month 等來回答。e.g.4. HOW Often do you borrow books from the library?TWiCe a InOnth 5 一HOW Often does your mother do the washing?She does it every day.6 一HOW Often Can you go to the

19、 movie?OnCe a week在大家所做的練習(xí)中，常見的有“句型轉(zhuǎn)換”。這種題型有一種“就劃線部 分提問”，要求針對陳述句中的劃線部分提出問題（也就是把陳述句變成特殊疑 問句），其中就有針對上面所說的頻度副詞或every day, each week, OnCe a week, twice a day, four times a InOnth等提問的句子。這時候自然要用how Often來提問 T O e.g.JaCk WatCheS TV three times a week. HOW Often does JaCk WatCh TV?OUr SChOOl has a SPOrtS m

20、eeting twice a year. How Often does your SChOOl have a SPOrtS Ineeting?要注意的是，陳述句在變成這種特殊疑問句時，其結(jié)構(gòu)是：Howoften+助動 詞+主語+實義動詞+其它成分？或：Howohen+系動詞be+主語+其它成分？ HOW Often ？和 HOW long. ?1) HOW Often do you WatCh TV?你多長時間看一次電視？回答能夠是下面的任何一種：EVery day./ OnCe a week./Three times a week./ Often./ 2) HOW IOng do you U

21、SUally WatCh TV?你通常看多長時間電視？回答能夠是下面的任何一種：AbOUt One hour./ Three hours. / Thirty minutes./.從以上例句中能夠看出：how Often意為"多久一次”；how long意為"多長時間"?！菊Z法知識聚焦】一般現(xiàn)在時 The SimPIe PreSent TenSe一般現(xiàn)在時的特殊疑問句Let's IOOk at the following SentenCeS first (讓我們先看看下面的句子)1) What do you USUany do On Weekends?2)
