4、ually通常often經(jīng)常sometimes有時(shí)候hardlyever很少，幾乎沒有never從不這些詞都是表示頻率的副詞，但是在程度上有差別。通常用于一般現(xiàn)在時(shí)。如:Ialwayshavesomemilkformybreakfast.我早餐總是喝牛奶。Heusuallygetsupat6:30inthemorning.他通常早上6：30起床。Heoftendoeshomeworkbeforedinnertime.他經(jīng)常晚餐前做作業(yè)。HesometimesgoestomoviesonFridayevening.他有時(shí)周五晚上去看電影。Ihardly/evereatoutatnoon.我很少中

6、ar每天（周/月/年）一（兩）次all,most,some,no的用法及差異。all“所有的，全體的”Allstudentsdohomeworkafterschool.Lastnight,Icookedallthevegetablesinthefridge.most“大多數(shù)的”Moststudentsplaycomputergamesonweekends.some“一些”SomestudentsgotoEnglishmovieseveryday.no“沒有”，注意這里no是形容詞。NostudentsreadEnglishnovels.我們可以看出：all,most,some,no放在名詞的前

14、ally,often,sometimes,never等表示時(shí)間頻度的副詞。這些詞通常用來說明在一段時(shí)間內(nèi)做某事的多少或某種狀態(tài)存在的次數(shù)的多少。例如：Weusuallygetupathalfpastsix.我們通常六點(diǎn)半起床。Sometimeshegoestoseehisgrandpaonweekends.周末，他有時(shí)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(dá)自己的或他人的一些行動，或者事物所存在的狀態(tài)。我們還要向?qū)Ψ教岢鲆恍﹩栴}，請求對方回答。在這種情況下，我們還要用疑問句。請看下面幾組對話：一Howoftendoyouplayfootball?Iusuallyplayf

15、ootballafterschool.一HowoftendoesMarygototheconcert?SheoftengoestoitonSaturdayevening.Howoftendoesmydaughtertakethemedicine?Threetimesaday.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(shí)間內(nèi)某種動作的次數(shù)”的狀語提問時(shí)，都要用howoften。換句話說，如果要回答由howoften提問的句子，我們通常要用頻度副詞或諸如everyday,eachweek,onceaweek,twiceaday,fourtimesamonth等來回答。e.g.Ho

16、woftendoyouborrowbooksfromthelibrary?Twiceamonth.Howoftendoesyourmotherdothewashing?Shedoesiteveryday.Howoftencanyougotothemovie?Onceaweek.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everyday,eachweek,onceaweek,twiceaday,fourtimesamonth等提問的句子。這時(shí)候自然要用howoft

17、en來提問了。e.g.JackwatchesTVthreetimesaweek.HowoftendoesJackwatchTV?Ourschoolhasasportsmeetingtwiceayear.Howoftendoesyourschoolhaveasportsmeeting?要注意的是，陳述句在變成這種特殊疑問句時(shí)，其結(jié)構(gòu)是：Howoften+助動詞+主語+實(shí)義動詞+其它成分？或：Howoften+系動詞be+主語+其它成分？Howoften？和Howlong.?HowoftendoyouwatchTV?你多長時(shí)間看一次電視？回答可以是下面的任何一種：Everyday./Onceawe
