頻度副詞學(xué)案

1、頻度副詞科目英語(yǔ)適用年級(jí)初中二年級(jí)適用區(qū)域全國(guó)使用人教版教材的地區(qū)課時(shí)數(shù)量/時(shí)間1課時(shí)/60分鐘教師姓名學(xué)生姓名教學(xué)U標(biāo)知識(shí)：1、熟悉常見的頻度副詞。2、掌握頻度副詞的用法以及位置。方法：1、要總結(jié)、熟記重要頻度副詞的用法；要學(xué)會(huì)在實(shí)際中靈活運(yùn) 用。能力：1、能正確運(yùn)用頻度副詞，。2、掌握并會(huì)運(yùn)用頻度副詞進(jìn)行正確表達(dá)句子。教學(xué)方法建議1、通過復(fù)習(xí)一般現(xiàn)在時(shí)，引出常見的頻度副詞，從而從根本上讓學(xué)生明 白頻度副詞的用法。2、進(jìn)行相應(yīng)的練習(xí)講解，分類講解，綜合練習(xí)。知識(shí)點(diǎn)常見頻度副詞，頻度副詞的等級(jí)，常見的頻度副詞的位置和用法教學(xué)過程：一、預(yù)習(xí)教師引導(dǎo)學(xué)生復(fù)習(xí)上節(jié)課留的作業(yè)，進(jìn)行評(píng)價(jià)并講解。二、知識(shí)

2、講解知識(shí)點(diǎn)1:常見的頻度副詞頻度副詞是表示與次數(shù)，頻度有關(guān)的副詞，如:always（總是），usually（通常）,frequently （經(jīng)常）often （經(jīng)常） sometimes （有時(shí)），seldom（不常）,rarely （極少），never （從不）once（一次）， twice （兩次），等。知識(shí)點(diǎn)2：頻度副詞等級(jí)：all the time 100%；almost , always 90%；generally , usually 80%；often , frequently 60-70%；as often as not 40-50%；sometimes , at times 2

3、0-30%；occasionally , from time to time 10%；hardly , seldom , rarely 5%；never 0%o知識(shí)點(diǎn)3：頻度副詞的位置以及用法 always頻率最高，表示動(dòng)作重復(fù)、狀態(tài)繼續(xù)，表示“一直、總是”，其反 義詞為nevero always等與not連用時(shí)，表示部分否定。如：The rich are not always happy.有錢的人并不總是快樂的。如果要變?yōu)榉穸ň?，?yīng)將always改為never才能全部否定。如:Li Ping is always late for school.李平上學(xué)總是遲到。Li Ping is neve

4、r late for school.（全部否定）Li Ping is not always late for school. （部分否定）頻度副詞通常和一般現(xiàn)在時(shí)連用，表示動(dòng)作發(fā)生的頻率。但always與進(jìn)行時(shí) 連用時(shí)，并不強(qiáng)調(diào)動(dòng)作正在進(jìn)行，而是表示贊嘆、厭煩等情緒。如：He is always thinking of others.他總是想著別人。（贊嘆）She is always asking silly questions.她總是問些愚蠢的問題。（厭 煩）The boy is always asking for money.這個(gè)小男孩總是要錢。（厭煩） usually意為“通?！?，表示習(xí)

5、慣性動(dòng)作或狀態(tài)，很少有例外。如：We usually go to school at seven in the morning.我們通常在早上七點(diǎn) 上學(xué)。My mother and I usually go shopping on Sundays.我和媽媽通常在星期 天去買東西。Often意為“經(jīng)常，時(shí)?！保硎痉磸?fù)性的動(dòng)作或狀態(tài)，中間有間斷，不 如usually那么頻繁。其反義詞是seldomo often在句尾時(shí)常被very或quite修 飾。如：It often rains here in April.這兒四月份常下雨。he boys often eat noodles and the

6、girls sometimes eat them 男生經(jīng) 常吃面條，女生有時(shí)吃。I often chat with my friends under the big tree.我經(jīng)常在這棵大樹下 和朋友聊天。He writes to his friends quite often.他常給他的朋友寫信。 sometimes意為"有時(shí)”，頻率不及often,表示動(dòng)作偶爾發(fā)生，間斷時(shí)間 較長(zhǎng)。其位置比較靈活，放在句首、句中、句末都可。如：Sometimes we go to the cinema and at other times we go for a walk有時(shí)我們?nèi)タ措娪?，有時(shí)我

7、們?nèi)ド⒉?。I sometimes watch TV in the evening.我有時(shí)晚上看電視。My father has lunch in the factory sometimes我父親有時(shí)在工廠吃午 飯。 seldom意為“很少” ；never意為“從不”。這兩個(gè)副詞表示否定意義, 動(dòng)作兒乎不會(huì)發(fā)生。如：He seldom eats breakfast他很少吃早餐。The little girl seldom goes out.這個(gè)小女孩很少外出。I w訂1 never forget your kindness.我永遠(yuǎn)忘不f你的好意。The boys never eat chocol

8、ate and the girls seldom eat it. 男生從不 吃巧克力，女生很少吃。Btter late than never.諺語(yǔ)遲到（遲做）總比不來（不做）好。 hardly具有否定意義，表示“兒乎不、簡(jiǎn)直不”，除非特殊情況，否則不 會(huì)發(fā)生。如：The boy is so young that he could hardly understand it. 這個(gè)孩子太 小了，不可能懂得這件事。對(duì)上述頻度副詞提問時(shí),用how ofteno如：I write to my brother sometimes.fHow often do you write to your brothe

9、r?位于助動(dòng)詞之前兩種惜況1. 為了表示強(qiáng)調(diào)，頻度副詞有時(shí)也可位于動(dòng)詞be、助動(dòng)詞、情態(tài)動(dòng)詞之前， 此時(shí)助動(dòng)詞等應(yīng)重讀。如：She always was late.她老是遲到。I never can remember.我永遠(yuǎn)也記刁、住。2. 在簡(jiǎn)略答語(yǔ)中，當(dāng)頻度副詞與動(dòng)詞be、助動(dòng)詞或情態(tài)動(dòng)詞位于句末時(shí)， 頻度副詞必須前置。一 "Philip is late again. ” 一 "Yes, he always is. 一 "菲利普乂遲 到了?！?一 “是的，他總是遲到。”uCan you park your car near the shops?" &

10、quot;Yes. I usuallycan.在否定句中的用法在否定句中，有的頻度副詞位于否定詞之前或之后均可，而有的頻度副詞則 必須位于否定詞之后，還有的頻度副詞卻必須要位于否定詞之前。大致情況如下:1. 頻度副詞usually和often可位于否定詞not之前或之后。他們不常開這樣的晚會(huì)。正：They don' t often hold such partiesIE： They often don' t hold such parties星期日我們一般不在9點(diǎn)以前起床。正：We don' t usually get up before nine on Sundays

11、IE： We usually don* t get up before nine on Sundays在否定句中，頻度副詞用于句中或句首，有時(shí)但會(huì)導(dǎo)致意思不同。He doesn' t usually sleep for two days at a time. 他很少一連睡兩 天。Usually he doesn' t sleep for two days at a time. 他連續(xù)兩天不睡覺 是常事。2. 頻度副詞always總是位于否定詞之后，不可位于否定句之前。Things are not always what they seem to be.外表往往是靠不住的。Sil

12、ence must not always be read as consent.沉默并不見得一定意味著同意。3. 頻度副詞sometimes總是位于否定詞之詢，不可位于否定詞之后。Jim is sometimes not very punctual.吉姆有時(shí)不太準(zhǔn)時(shí)。Debbie is sometimes not responsible for what she does. 黛比有時(shí)對(duì)她 所做的事不負(fù)責(zé)任。位于句末的用法1. sometimes?？捎糜诰淠Ｈ纾篧e all get into trouble sometimes.我們有時(shí)都會(huì)遇到麻煩。You can' t work al

13、l the time, it does you good to go out and enjoy yourself sometimes.你不能總是工作，有時(shí)出去放松一下會(huì)對(duì)你有好處。2. often有時(shí)可置于句末，但通常會(huì)帶有very, quite, fairly, more, so 等修飾語(yǔ)。如：We' ve been there quite often.經(jīng)常去那里。When I was young, I used to play tennis very often.我年輕時(shí)經(jīng)常扌J 網(wǎng)球。Diana used to travel a lot. These days she doesn' t go away
