Lets look at the following words and their usage.频度副词：always,usually,often,sometimes,hardly和never是英语中最常见的频度副词，它们在句中的位置大致相同：通常放在行为动词之前，系动词be、助动词和情态动词之后。但它们所表示的含义及频度是各不相同的。（1）always的频度为100%，表示动作重复、状态继续，中间没有间断，意思是“总是”、“永远地”。例如：Thesunalwaysrisesintheeastandsetsinthewest. 太阳总是东升西落。Customersarealwaysright. 顾客永远是对的。always与进行时态连用，并不强调动作正在进行，而是表示说话人的“赞扬”、“不满”、“厌烦”等情绪，有强烈的感情色彩。例如：Sheisalwaysthinkingofhowshecandomoreforpeople. 她总是在考虑怎样为人们多做些事。（表示赞扬）Hewasalwaysaskingformoney. 他总是要钱。（表示厌烦）Sheisalwaysaskingforleave. 她总是请假。（表示不满）always与not连用，表示部分否定，意思是“不总是”。例如：Thericharenotalwayshappy. 有钱人未必总是幸福的。（2）usually的频度为70%左右，意为“通常”、“平常”，即很少有例外。例如：Heusuallygoestobedattenoclock. 他通常10点钟睡觉。（3）often的频度为50%左右，意为“常常”，但不如usually那么频繁，表示动作重复，中间有间断。例如：Heisoftenlateforschool. 他上学经常迟到。veryoften语气比often重，常位于句首或句末。例如：HedoesntgotoLondonveryoften. 他不常去伦敦。（4）sometimes的频度为20%左右，意为“有时”，表示动作偶尔发生。可以位于句首，以示强调。例如：Itissometimeshotandsometimescold. 天气忽冷忽热。Sometimeshedoesitthiswayandsometimeshedoesitthatway. 他有时这样做，有时那样做。He sometimes goes to movies on Friday evening. 他有时周五晚上去看电影。（5）hardly的频度为5%左右，意为“几乎不”、“简直不”，常和ever连用表示强调。例如：Ihardlyevergooutthesedays. 这些天我几乎不出门。（6）never的频度为0，意为“从来不”、“永不”。例如：Myparentsareneverlateforwork.我父母上班从来不迟到。2.注意sometimes与几个形似的词的区别。(1)sometime是副词，意为“在某个时候”，“某时”e.g：Willyoucomeagainsometimenextweek?Shewastheresometimelastyear.(2)sometime是名词词组，意为“一段时间”，做时间状语用e.g：Iwillstayhereforsometime.Heworkedonthetroubleforsometime.(3) sometimes是名词词组，意为“几次，几倍”。e.g：Imethimsometimesinthestreetlastmonth.Thefactoryissometimeslargerthanthatone.3.不定代词all“所有的，全体的”，most“大部分的，大多数的”，some“一些”，no“没有一个”的用法，这些词可以在句中作主语、宾语、表语或定语。e.g：Allthewaitersintherestaurantareverybusy.Allthestudentsinourschoolhavetowearschooluniforms.Iknowmostpeopleinthisparty. Most students play computer games on weekends.Ginahassomebeautifulscarves. Some students go to English movies every day. Nochildrencansingthissong. all, most, some, no 放在名词的前面做定语，表示数量的多少。4.疑问词how的用法（1）怎样，用什么手段，方法。Howdidhedoit?Idontknowhowtoswim.（2）情况如何（指身体健康状况）Howareyou? HowsitgoingwithTom?（3）howmany，howmuch表示“多少”howmany后接可数名词复数，howmuch接不可数名词。Howmanytimesdoyougotothepark?Howmanyticketsdoweneed?How much water do we need every day?Howmucharethosepants?（4）howoften是对动作发生的“次数”提问,询问的是频率“多久一次”回答可以是：Every day./ Once a week./Three times a week./ Often./ .eg：Howoftendoyouplaytennis?Howoftendoyousurftheinternet.(5) How long. ? 询问的是时间长短“多长时间”回答可以是：About one hour./ Three hours. / Thirty minutes./. How long do you usually watch TV? 你通常看多长时间电视？5.time表示不可数名词，意为“时间”。 表示可数名词，意为“次数，倍数”。eg：Whattimeisit?Timeandtideneverwaitformen.Igotothemoviesthreetimesaweek.Thesizeofthenewmuseumisfourtimeslargerthantheoldone.注意“次数”的表达方法一次once，两次twice，三次或三次以上用基数词加上times，threetimes、fivetimes、onehundredtimes.表示“几次”的表达方法是：once a day/ a week/ a month/ a year twice a day/ a week/ a month/ a year 6. She says its good for health. 她说它对健康有利。begoodfor意为“对有好处”，其反义词为“bebadfor”。eg：Drinkingmilkisgoodforyourhealth.Eatingtoomuchsugarisbadforyourteeth.ReadingEnglishisgoodforstudyingEnglish.7.asfor意为“就而论”，“至于”eg：Asforfruit，Ieatitsometimes.8. My mother wants me to drink it. 我妈妈想要我喝。 want sb. to do sth. 想要某人干某事 eg：I want you to help me with my math.我想要你帮我学数学。有很多动词后面用这种结构做动词的复合宾语。如：asksb.todosth. tellsb.todosth. helpsb.(to)dosth.等9.exercise的用法。（1）作可数名词复数exercises。意为“运动、体操”。（2）作不可数名词，意为“练习、习题”。eg：Ihavetodosomuchexercise.Heboughtanewexercisebook.（3）作动词，意为“练习、运动”。eg：Howoftendoyouexercise?Iexerciseeveryday.10. 语法：一般现在时的特殊疑问句 1) What do you usually do on weekends? 2) What does he do on weekends? 3) How often do you shop? 4) How often does he watch TV? 5) How many hours do you sleep every night? 一般现在时的特殊疑问句的构成： 特殊疑问词+一般疑问句这里的特殊疑问词指 what, what time, where, when, which, who, whom, whose, why, how, how many, how much, how long, how often六、课文解析SB.3abutImprettyhealthy.Iexerciseeveryday,usuallywhenIcomehomefromschool.Andmyeatinghabitsareprettygood.Itrytoeatalotofvegetables,usuallytentoeleventimesaweek.AndIeatfruiteverydayandIdrinkmilkeveryday.Ofcourse,Ilovejunkfood,too,butItrytoeatitonlyonceaweek,oh,andIsleepninehourseverynight.Soyousee,Ilookaftermyhealth.Andmyhealthylifestylehelpsmegetgoodgrade.Goodfoodandexercisehelpmetostudybetter.1.pretty表示“十分”作副词用，我们以前学过quite和very也有这种意思。其中它们的程度由浅入深为quite pretty very.eg：Heisquiteserious.Itsoundsprettygood.NinacansingEnglishsongsverywell.2.Iexerciseeveryday,usuallywhenIcomehomefromschool.我每天锻炼身体，通常是放学后。3.eatinghabits“饮食习惯”。4.trytodosth意为“尽力去做某事”。 eg：Trytogethereearly.Hetriedtopasstheexam.5.tentoeleventimesaweek.“每周十到十一次”。注意这种表达。“to”为介词。翻译：（1）两到三次。twicetothreetimes.（2）每月四到五次。fourtofivetimesamonth.6.Ofcourse.当然。7.Soyousee,Ilookaftermyhealth. 所以你看，我很在意我的健康。lookafter意为“照顾、照看”。eg：CanyoulookaftermybabywhenIleave?Pleaselookafteryourownbagscarefully.look还可以和许多词搭配，但意思不一样。（1） lookat“看，认真地看”。 eg：Pleaselookattheblackboard.Somepeoplearelookingatthenotice.（2） lookfor “寻找” eg：OldHenrylookedforhisdogs,buthedidntfindit.Imlookingformylostpen.8.Goodfoodandexercisehelpmetostudybetter. 好的饮食和锻炼帮助我学得更好。【模拟试题】一. 翻译词组1.很少/几乎不曾_ 2.surfthe Internet_3.大部分学生_ 4.asfor_5.一周两次_ 6.begoodfor_7.照顾_ 8.eatinghabits_ 9.六到八次_ 10.trytodosth._ _二.用括号内所给词的正确形式填空。1.My_（eat）habitsareprettygood.2.Youmusteatmorevegetablesandkeep_（health）.3.Therearemany_（different）betweenthetwobooks.4.Thismovieisvery_（interest）5.Mymomwantsme_（drink）milkeveryday.三.选择填空1.Howoftendoesheexercise? _.A.Heistwelve B.Heexercisesbybus C.Twiceaweek D.Aboutonehour.2.Myfatherwantsme_vegetableseveryday.A.toeat B.eating C.eat D.eats3.80%studentslikethewatch.Whatdoes“80%”mean?_.A.Noneofthestudents B.Allthestudents C.Someofthestudents D.Mostofthestudents4.HaveyoueverbeentoHaiNan?No,_.A.ever B.never C.sometimes D.usually5.Mikeisa_boy.Hedoesexerciseeveryday.A.health B.unhealthy C.healthy D.healthily6.Isyourbook_asmine?
