知識精講1

  1.I'm learning/learn a lot today.

  一般現在時(shí)和現在進(jìn)行時(shí)的用法區別英語(yǔ)中的一般現在時(shí)和現在進(jìn)行時(shí)在用法上有著(zhù)許多相似之處,但又有著(zhù)本質(zhì)的區別。傳統的英語(yǔ)語(yǔ)法書(shū)籍從沒(méi)有將這兩種時(shí)態(tài)的諸多相似的用法聯(lián)系起來(lái)分析、比較,這極易使英語(yǔ)初學(xué)者在理解和記憶這些用法時(shí)產(chǎn)生混淆。下面我就這兩種時(shí)態(tài)的相似用法作一橫向的比較。

  充當將來(lái)時(shí)的一般現在時(shí)與現在進(jìn)行時(shí)在用法上的區別:

  (1)一般現在時(shí)表示將來(lái)時(shí)間時(shí),用于時(shí)間表、節日單或日程表上所安排好的事情:

  The conference begins at 8:30 and ends at 10.

  We leave tomorrow at 6:30 and arrive at 10

  June 8 marks our 10 th wedding anniversary.

  在這種用法中,句中動(dòng)詞多為go,come,sail,start,return,open,close,takeoff,land等。

  (2)現在進(jìn)行時(shí)表示將來(lái)時(shí)間時(shí),則強調個(gè)人在最近要做的事先安排、計劃好的事情,常跟表示未來(lái)的時(shí)間狀語(yǔ):

  I am spending next summer in Alaska.

  They are having a holiday next Saturday.

  He is arriving tomorrow morning on the 6:30 tram.

  I'm seeing Linda this evening.

  比較:一般現在時(shí)與現在進(jìn)行時(shí)均可表示最近按計劃安排要做的事,但前者表示某個(gè)集體或組織的計劃,而后者表示個(gè)人的計劃。如:

  I leave for Changchun tomorrow.(我和其他成員一起去,且該計劃也不是我個(gè)人定的)

  I am leaving tomorrow.(我個(gè)人的計劃)

  與高頻副詞連用的一般現在時(shí)和現在進(jìn)行時(shí)在用法上的區別:

  (1)一般現在時(shí)與高頻副詞(always,constantly,forever,perpetually,repeatedly)連用時(shí)表示經(jīng)常性發(fā)生的動(dòng)作,如:

  Tom always helps me with my work.

  He is nearly always at home in the evening.

  (2)現在進(jìn)行時(shí)與高頻副詞也表示經(jīng)常性發(fā)生的動(dòng)作,但它還同時(shí)強調說(shuō)者對某人所做事情的贊揚或批評(如欣賞、厭倦等),如:

  I'm always hearing strange stories about him.

  She's always helping people (changing her mind).

  Our fire alarm is forever going off for no reason.

  She is always coming late for work.

  與某些可持續動(dòng)詞或形容詞連用的一般現在時(shí)和現在進(jìn)行時(shí)在用法上的區別:

  (1)一般現在時(shí)與某些可持續動(dòng)詞或形容詞連用時(shí)可表示習慣性的動(dòng)作或一般存在的狀態(tài),如:

  The river flows slowly.

  Bill is very clever.

  The boy is naughty.

  The car works perfectly.

  (2)而現在進(jìn)行時(shí)與某些可持續動(dòng)詞或形容詞連用則強調該動(dòng)作或狀態(tài)的暫時(shí)性,表示不能長(cháng)期發(fā)生的動(dòng)作或存在的情況:

  The river is flowing fast after the heavy rain.

  (只是在暴雨之后河水才變得湍急了)

  He's being very clever today.

  (他平時(shí)的智力表現平平甚至愚蠢,今天卻一反常態(tài))

  The child is being naughty.

  (這孩子平時(shí)很聽(tīng)話(huà),這會(huì )兒卻很淘氣)

  The car is working perfectly.

  (這車(chē)子平時(shí)總出毛病,這會(huì )兒工作得倒挺不錯)

  一般現在時(shí)和現在進(jìn)行時(shí)與感覺(jué)動(dòng)詞連用時(shí)在用法上的區別:

  (1)感覺(jué)動(dòng)詞與一般現在時(shí)連用時(shí),表示無(wú)意的感覺(jué)行為(如無(wú)意中聽(tīng)見(jiàn)或看見(jiàn)),如:

  I notice a change in the way he is dressed.

  They all smell something burning.

  He feels cold.

  (2)感覺(jué)動(dòng)詞與現在進(jìn)行時(shí)連用時(shí),表示有意的感覺(jué)行為,如:

  I am smelling these new perfumes and trying to decide which to buy.

  I'm feeling this material to see whether it is pure silk or not.

  I am listening to the radio.

  一般現在時(shí)和現在進(jìn)行時(shí)在命令句中的用法區別:

  (1)一般現在時(shí)用來(lái)表示語(yǔ)氣強硬的命令或警告,如:

  You finish the assignment before 4 o'clock this afternoon.

  你必須在今天下午4點(diǎn)鐘以前完成任務(wù)。

  You mind your own business.

  你少管我的事(管好你自己吧)。

  (2)現在進(jìn)行時(shí)用來(lái)表示語(yǔ)氣較溫和的命令或要求,如:

  You are standing next to Tom,Bill.

  Don't just stand by. You are helping me with this.

知識精講2

I've lost/lost my key. Can you help me look for it?

  現在完成時(shí)和一般過(guò)去時(shí)的用法區別

  現在完成時(shí)和一般過(guò)去時(shí)都表示過(guò)去的動(dòng)作,區別在于該動(dòng)作是否與現在發(fā)生聯(lián)系:過(guò)去時(shí)的動(dòng)作與現在無(wú)大聯(lián)系;而現在完成時(shí)的動(dòng)作結果一直影響到現在,也許還在持續。

  I didn't have my breakfast yesterday.

  (昨天是否吃早飯和現在沒(méi)什么關(guān)系)

  You have studied for two years in this university.

  for表示一段時(shí)間,在現在完成時(shí)中經(jīng)常用到,和since接一個(gè)過(guò)去的時(shí)間點(diǎn)。

  The English chief engineer has stayed in China for ten months.

  The English chief engineer has stayed in China since ten months ago.

  I have worked as Chairman of the Student Union since I came to the university.

  注意:現在完成時(shí)中不能直接用表示過(guò)去的時(shí)間狀語(yǔ)。

  我們不能說(shuō)The English chief engineer has stayed in China last year.

知識精講3

It was the most exciting day of my life.

  How can I write with a broken arm?

  現在分詞與過(guò)去分詞作定語(yǔ)比較

  由于現在分詞和過(guò)去分詞具有形容詞或副詞的特點(diǎn),在句中可作表語(yǔ)、狀語(yǔ)、賓語(yǔ)補足語(yǔ)和定語(yǔ)。作定語(yǔ)時(shí),既可作前置定語(yǔ),又可作后置定語(yǔ)。現將其用法歸納如下,供大家參考。

  前置定語(yǔ):?jiǎn)为氁粋(gè)分詞作定語(yǔ)時(shí),一般情況下被放在被修飾的名詞前面,例如:

  (1)現在分詞:幾乎所有的現在分詞都可以作前置定語(yǔ),現在分詞表示它所修飾名詞的動(dòng)作,二者有邏輯上的主謂關(guān)系,并且表示所修飾詞的特點(diǎn)、性質(zhì)等。(可以轉換成定語(yǔ)從句)如:

  Barking dogs seldom bite.=Dogs which barks seldom bite.

  愛(ài)叫的狗很少咬人。

  (2)過(guò)去分詞:所有的及物動(dòng)詞的過(guò)去分詞都可以作前置定語(yǔ),不及物動(dòng)詞過(guò)去分詞作前置定語(yǔ)時(shí),一般過(guò)去分詞前有副詞修飾,但也有少數幾個(gè)可以單獨作前置定語(yǔ)。過(guò)去分詞與已經(jīng)完全變成了形容詞的過(guò)去分詞作前置定語(yǔ)的區別是:前者表示中心詞承受動(dòng)作的結果或狀態(tài);而后者表示中心詞的特點(diǎn)。如:

  a newly arrived student新到的學(xué)生(arrived是不及物動(dòng)詞,但前有newly修飾)

  an escaped convict逃犯(escaped是不及物動(dòng)詞)

  a retired worker退休工人(retired是不及物動(dòng)詞)

  a locked door上鎖的門(mén)(locked表示中心詞door鎖后的狀態(tài))

  an experienced doctor有經(jīng)驗的醫生(experienced表示中心詞doctor的特點(diǎn))

  后置定語(yǔ):

  (1)當被修飾的詞是由some/any/no+thing/body/one所構成的不定代詞或指示代詞those等時(shí),雖然是一個(gè)單一的分詞作形容詞用,但也要放在其后。(可變?yōu)槎ㄕZ(yǔ)從句)如:

  There has been nothing changed since I left Harbin two years ago.

  自從兩年前離開(kāi),哈爾濱一直沒(méi)有什么變化。

  (2)當分詞短語(yǔ)作定語(yǔ)時(shí),一定要放其之后。如:

  The bottle containing (=which contained ) the poison was sent to the laboratory.

  盛毒品的瓶子被送到實(shí)驗室。

  They have Intimate knowledge of the subject being investigated (=which is being investigated ).

  他們對所研究的題目非常熟悉。

  注意:現在分詞的完成式不能作后置定語(yǔ)。但是,如果中心詞是泛指的,偶爾可用現在分詞的完成式作后置定語(yǔ)。如:不能說(shuō):

  The man having written that book is our teacher.

  應該說(shuō):

  The man who has written that book is our teacher,

  寫(xiě)那本書(shū)的人是我們的老師。

知識精講4

Your house is three times larger than mine.

  比較結構的用法:

  1)比較級+than

  You are taller than I.

  注意:

  要避免重復使用比較級。

  (錯)He is more cleverer than his brother.

  (對)He is more clever than his brother.

  (對)He is cleverer than his brother.

  要避免將主語(yǔ)含在比較對象中。

  (錯)China is larger than any country in Asia.

  (對)China is larger than any other country in Asia.

  要注意對應句型,遵循前后一致的原則。

  The population of Shanghai is larger than that of Beijing.

  It is easier to make a plan than to carry it out.

  要注意冠詞的使用,后有名詞的時(shí)候,前面才有可能有名詞。

  比較:Which is larger,Canada or Australia?

  Which is the larger country,Canada or Australia?

  she is taller than her two sisters.

  She is the taller of the two sisters.

  2)as+形容詞或副詞原級+as在否定句中可用so…as。

  He cannot run so/as fast as you.

  當as…as中間有名詞時(shí)采用以下格式。

  as+形容詞+a+單數名詞

  as+many/much+名詞

  This is as good an example as the other is.

  I can carry as much paper as you can.

  用表示倍數的詞或其他程度副詞作修飾語(yǔ)時(shí),放在as的前面。

  This room is twice 9s big as that one.

  Your room is the same size as mine.

  倍數+as+adj.+as=倍數+the名詞+of

  This bridge is three times as long as that one.

  This bridge is three times the length of that one.

  Your room is twice as large as mine.

  Your room is twice the size of mine.

-What would you like to do?

  -I'd prefer to continue the conversation.

  prefer用法種種

  prefer意為“寧可、寧愿、更喜歡”,其后可以接名詞、代詞、動(dòng)詞不定式、動(dòng)名詞或從句,還可以構成固定句型。由于該詞后可接的成分多,用法靈活,許多同學(xué)對這個(gè)詞的諸多用法常常容易弄混淆。為了便于同學(xué)們掌握和用好它,筆者對prefer的八種常見(jiàn)搭配作出以下歸納。

  (1)prerfer+n. (pron.) 寧愿,更喜歡

  Which do you prefer,rice or bread?

  你比較喜歡哪一樣,米飯還是面包?

  I prefer some poems and short stories.

  我寧愿讀一些詩(shī)和短篇小說(shuō)。

  (2)prefer to do sth.寧愿做某事(強調特定的或某次具體的動(dòng)作,即在一定的場(chǎng)合下寧愿做什么)

  I prefer swimming,but I don't prefer to swim now.

  我喜歡游泳,但我現在不想游。

  (本句強調prefer to do與prefer doing結構的區別,prefer swimming指“一般愛(ài)好”,don't prefer to swim強調某次具體的行為,即現在由于種種原因而“不想去游泳”。)

  (4)prefer+(doing) sth.+to (doing) sth.

  寧愿選擇……寧愿……而不愿……

  She seems to prefer cats to dogs.

  貓和狗之間她似乎更喜歡貓。

I'd rather go to the cinema than stay at home and watch TV.

  would rather用法淺析

  “would rather+動(dòng)詞原形”是英語(yǔ)中常見(jiàn)的一個(gè)慣用句式(美國英語(yǔ)中多用had rather)。'd rather為would(或had)rather的縮寫(xiě)形式。Would (had ) 在此決無(wú)“過(guò)去”之意,且無(wú)詞性、時(shí)態(tài)變化,它是一個(gè)情態(tài)助動(dòng)詞。該句式常用來(lái)表示選擇的意愿,意為“寧可……”“寧愿……”“最好……”。如:

  He'd rather work in the countryside.

  他寧可到農村去工作。

  If you'd rather be alone,we'll all leave here.

  如果你寧愿獨自呆著(zhù),那我們都離開(kāi)這兒。

  You would rather stay at home and do some reading this evening.

  今晚你最好呆在家中讀點(diǎn)書(shū)。

  would rather與than連用.可構成另一個(gè)慣用句式,即“would rather…than…”,意為“寧可(愿)……(而)不要(愿)……”“與其……不如……”。用以表達主語(yǔ)的意愿。強調經(jīng)過(guò)選擇后做其中一件事,而不愿做另一件事。如:

  I would rather watch TV at home than walk outside.

  我寧可在家看電視而不愿到外邊散步。

  在使用“would rather…than…”句型時(shí)。應注意以下幾點(diǎn):

  (1)如該句型前后連接的兩個(gè)動(dòng)詞相同,則than之后的那個(gè)動(dòng)詞可省去。如:

  I'd rather you know that now than afterwards.

  我于可你現在就知道這件事.而不是以后。

  (2)would rather…than…也可改寫(xiě)成“would…rather than…”,其用法及含義仍不變。如:

  Facing the enemies,our soldiers would die rather than surrender.

  面對敵人,我們的戰士寧死不屈。

  (3)有時(shí),為表示語(yǔ)氣上的強調,可將rather than置于句首。如:

  Rather than refuse to help you,I would borrow money from my friends.

  我寧可向朋友借錢(qián),也不愿拒絕幫助你。

  (4)would rather后也可跟從句,表示主語(yǔ)寧愿讓某人干某事。這時(shí),從句謂語(yǔ)動(dòng)詞要用虛擬語(yǔ)氣,即用一般過(guò)去時(shí)表示現在或將來(lái)要做的事;用過(guò)去完成時(shí)表示過(guò)去要做的事。如:

  I'd rather she set out to do the work now.

  我寧愿她現在就著(zhù)手做這項工作。

  (5)would rather后還可接動(dòng)詞的完成時(shí),表示主語(yǔ)要做某事,而結果事與愿違的意思。如:

  I'd rather have left a note on her desk.

  我本想留張字條在她書(shū)桌上的。(事實(shí)上沒(méi)有留)
