maybe/meɪbi/adv.大概；或许；可能考向讲解来自《点拨》知识点1【辨析】maybe与maybeeg：Maybeheknowsthewaytothezoo.也许他知道去动物园的路。maybe副词，意思是“也许，可能”，在句中作状语，相当于perhaps，常位于句首。Hemaybeintheoffice.=Maybeheisintheoffice.他或许在办公室。maybe/meɪbi/adv.大概；或许；讲解来自《点拨》巧记maybe与maybe：合并作状语，分开作谓语。舍maybe仍有意，丢maybe可不成。maybemay是情态动词，be是动词原形，两者构成完整的谓语形式，意为“也许是，可能是”。特色土方法讲解来自《点拨》巧记maybe与maybe：合并作状语，分频度副词概念及构成

考点在一般现在时态的句子中，常出现usually，often，sometimes，never等表示频率的状语。这些词在英语中被称为频度副词。一般来说可按频率大小排列为：always（总是）>usually（通常）>often（常常；经常）>sometimes（有时）>hardlyever（几乎从不）>never（从不）等。语法讲解频度副词概念及构成考点在一般现在时态的句子频度副词放在系动词be、助动词或情态动词之后，行为动词之前。eg：Heisalwaysaskingformoney.他总是要钱。Weoftenhavelunchatschool.我们经常在学校吃午饭。考向一频度副词放在系动词be、助动词或情态动词考向一典例—Doyoulikegoingmountainclimbing？—Yes，I

doitonweekendswithmyfriends.（漳州）A.seldom

B典例—Doyoulikegoingmountain有些频度副词可放在句首或句尾，用来表示强调。eg：SometimesIwalkhome，andsometimesIgohomebybus.我有时步行回家，有时乘公共汽车回家。考向二never位于句首，句子要倒装。eg：NeverhaveIlearntthisword.我从未学过这个单词。拓展有些频度副词可放在句首或句尾，用来表示考向二never位于频度副词用法：行前系后情助后，句首句末表强调。（行—行为动词；系—系动词be；情—情态动词；助—助动词）典例Never

（我能见到）thisgirlagain.【点拨】never放在句首时，句子要倒装。句意为：我再也不能见到这个女孩了。

canIsee特色土方法频度副词用法：行前系后情助后，句首句末表典例Neveronce，twice，threetimes...次数构成频率的表达方式（1）次数＋a＋时间（年/月/日/分……）（2）次数＋every＋基数词＋时间（年/月/日/分……）eg：onceayear每年一次twiceamonth每月两次onceeveryfouryears每四年一次seventimeseverytwominutes每两分钟七次考向三once，twice，threetimes...次数构成频对频度副词提问时，一般用howoften（多久一次）。eg：—Howoftendoyouexercise？你多久锻炼一次？—Onceamonth.每月一次。考向四拓展【难点】everytwodays＝everyotherday每两天对频度副词提问时，一般用howoften考向四拓展【难点】典例—

B.HowoftenC.Howlong【点拨】本题用寻找题眼法。由答语中“twiceaweek”可知问句对频率提问。

B典例—doesyourfathergoto【辨析】howoften与howmanytimeshowoften多久一次，用来询问在某一段时间内进行某个动作的次数。howmanytimes多少次，它不问动作发生的频率，只询问次数，即“多少次”。其答语为once，twice，threetimes等。eg：—HowmanytimeshaveyoubeentoBeijing？你去过北京几次？—Onlytwice.仅两次。—HowoftendoyougotoBeijing？你多久去一次北京？—Twiceamonth.每个月两次。拓展【辨析】howoften与howmanytimes拓展Completethequestionswithdoordoes.Thenmatchthequestionsandanswers.3a1.Howoften
