（2）次數(shù)+一段時(shí)間onceaday/twiceaweek/onceortwiceayear/twoorthreetimes

（3）頻度副詞always（100%）---usually（90%）---often=allthetime=attimes（60%）---sometimes（30%）---hardlyever（10-20%）---never（0%）=seldom頻度副詞

在一般現(xiàn)在時(shí)態(tài)的句子中，常出現(xiàn)usually，often，sometimes，never等表示頻率的狀語。這些詞在英語中被稱為頻度副詞。一般來說可按頻率大小排列為：always（總是）>usually（通常）>often（常常；經(jīng)常）>sometimes（有時(shí)）>hardlyever（幾乎從不）>never（從不）等。Grammar頻度副詞放在系動(dòng)詞be、助動(dòng)詞或情態(tài)動(dòng)詞之后，行為動(dòng)詞之前。Heisalwaysaskingformoney.他總是要錢。Weoftenhavelunchatschool.我們經(jīng)常在學(xué)校吃午飯。Grammar有些頻度副詞可放在句首或句尾，用來表示強(qiáng)調(diào)。

SometimesIwalkhome，andsometimesIgohomebybus.我有時(shí)步行回家，有時(shí)乘公共汽車回家。never位于句首，句子要倒裝。eg：NeverhaveIlearntthisword.我從未學(xué)過這個(gè)單詞。拓展Grammar頻度副詞用法：行前系后情助后，句首句末表強(qiáng)調(diào)。（行—行為動(dòng)詞；系—系動(dòng)詞be；情—情態(tài)動(dòng)詞；助—助動(dòng)詞）Never

（我能見到）thisgirlagain.canIseeGrammaronce，twice，threetimes...次數(shù)構(gòu)成頻率的表達(dá)方式（1）次數(shù)＋a＋時(shí)間（年/月/日/分……）（2）次數(shù)＋every＋基數(shù)詞＋時(shí)間（年/月/日/分……）eg：onceayear

twiceamonth

onceeveryfouryears

seventimeseverytwominutes次數(shù)+一段時(shí)間每年一次每月兩次每四年一次每兩分鐘七次Grammar對頻度副詞提問時(shí)，一般用howoften（多久一次）。eg：—Howoftendoyouexercise？你多久鍛煉一次？—Onceamonth.每月一次。拓展everytwodays＝everyotherday每兩天;每隔一天Grammar【辨析】howoften與howmanytimeshowoften多久一次，用來詢問動(dòng)作發(fā)生的頻率。howmanytimes多少次，它不問動(dòng)作發(fā)生的頻率，只詢問次數(shù)，即“多少次”。其答語為once，twice，threetimes等。eg：—HowmanytimeshaveyoubeentoBeijing？你去過北京幾次？

—Onlytwice.

—HowoftendoyougotoBeijing？

—Twiceamonth.僅兩次。你多久去一次北京？每個(gè)月兩次。Grammar4.①hardly只用作副詞，其意思是“幾乎不”，它常和can,could等連用，在句中位于be動(dòng)詞、情態(tài)動(dòng)詞或助動(dòng)詞之后、行為動(dòng)詞之前。e.g.HecanhardlyspeakEnglish.

他不太會(huì)說英語。

hardlyever幾乎從不

e.g.Peterishardlyeverlate.

②hard也用副詞，意為“努力地、刻苦地”e.g.Heworkshardonlybeforeexams.

他只在考試前努力學(xué)習(xí)。

Grammar

maybe/me?bi/adv.大概；或許；可能【辨析】maybe與maybemaybe副詞，意思是“也許，可能”，在句中作狀語，相當(dāng)于perhaps，常位于句首。maybemay是情態(tài)動(dòng)詞，be是動(dòng)詞原形，兩者構(gòu)成完整的謂語形式，意為“也許是，可能是”。eg:Hemaybeintheoffice.他或許在辦公室。=Maybeheisintheoffice.舍maybe仍有意，丟maybe可不成。Grammar他可能是個(gè)老師Hemaybeateacher.=Maybeheisateacher.他可能在教室Hemaybeintheclassroom.Maybeheisintheclassroom他可能今天下午來你可能不能通過考試Maybeyoucan’tpasstheexamMaybeshewillcomethisafternoon.—Ican’tfindmydictionary.—________youputitinthatbag.A.MustB.MayC.MaybeD.Maybe
