    小升初一般現(xiàn)在時課件講解

      一般現(xiàn)在時的特征是1.表示事物或人物的特征、狀態(tài)。如:The sky is blue.天空是藍(lán)色的。2.表示經(jīng)常性或習(xí)慣性的動作。如:I get up at six every day.我每天六點(diǎn)起床。3.表示客觀現(xiàn)實(shí)。以下是小編整理的小升初一般現(xiàn)在時課件講解,歡迎閱讀。

    小升初一般現(xiàn)在時課件講解

      一. 概念

      時態(tài)是英語謂語動詞的一種形式,表示動作發(fā)生的時間和所處的狀態(tài).英語中的時態(tài)是通過動詞形式本身的變化來實(shí)現(xiàn)的.英語有16種時態(tài),但中學(xué)階段較常用的有十種:一般現(xiàn)在時,一般過去時,一般將來時,過去將來時,現(xiàn)在進(jìn)行時,過去進(jìn)行時,將來進(jìn)行時,過去完成時,英在完成時和現(xiàn)在完成進(jìn)行時.

      二.相關(guān)知識點(diǎn)精講

      1.一般現(xiàn)在時的用法

      1) 經(jīng)常性或習(xí)慣性的動作,常與表示頻腮度的時間狀語連用。時間狀語: every…, sometimes, at…, on Sunday。例如:

      I leave home for school at 7 every morning. 每天早上我七點(diǎn)離開家。

      2) 客觀真理,客觀存在,科學(xué)事實(shí)。例如:

      The earth moves around the sun. 地球繞太陽轉(zhuǎn)動。

      Shanghai lies in the east of China. 上海位于中國東部。

      3) 表示格言或警句。例如:

      Pride goes before a fall. 驕者必敗。

      注意:此用法如果出現(xiàn)在賓語從句中,即使主句是過去時,從句謂語也要用一般現(xiàn)在時。

      例:Columbus proved that the earth is round. 哥倫布證實(shí)了地球是圓的。

      4) 現(xiàn)在時刻的狀態(tài)、能力、性格、個性。例如:

      I dont want so much. 我不要那么多。

      Ann writes good English but does not speak well. 安英語寫得不錯,講的可不行。

      比較:Now I put the sugar in the cup. 把糖放入杯子。

      I am doing my homework now. 我正在做功課。

      第一句用一般現(xiàn)在時,用于操作演示或指導(dǎo)說明的示范性動作,表示言行的瞬間動作。第二句中的now是進(jìn)行時的標(biāo)志,表示正在進(jìn)行的動作的客觀狀況,所以后句用一般現(xiàn)在時。

      2. 一般過去時的用法

      1)在確定的過去時間里所發(fā)生的動作或存在的狀態(tài)。例如:時間狀語有:yesterday, last week, an hour ago, the other day, in 1982等。例如:

      Where did you go just now? 剛才你上哪兒去了?

      2)表示在過去一段時間內(nèi),經(jīng)常性或習(xí)慣性的動作。例如:

      When I was a child, I often played football in the street. 我是個孩子的時候,常在馬路上踢足球。

      Whenever the Browns went during their visit, they were given a warm welcome.

      那時,布朗一家無論什么時候去,都受到熱烈歡迎。

      3)句型:It is time for sb. to do sth "到……時間了" "該……了"。例如:It is time for you to go to bed. 你該睡覺了。

      It is time that sb. did sth. "時間已遲了" "早該……了" ,例如It is time you went to bed. 你早該睡覺了。

      would (had) rather sb. did sth. 表示寧愿某人做某事。例如:Id rather you came tomorrow.還是明天來吧。

      4) wish, wonder, think, hope 等用過去時,作試探性的詢問、請求、建議等,而一般過去時表示的動作或狀態(tài)都已成為過去,現(xiàn)已不復(fù)存在。例如:I thought you might have some. 我以為你想要一些。

      比較:Christine was an invalid all her life.(含義:她已不在人間。)

      Christine has been an invalid all her life.(含義:她現(xiàn)在還活著)

      Mrs. Darby lived in Kentucky for seven years. (含義:達(dá)比太太已不再住在肯塔基州。)

      Mrs. Darby has lived in Kentucky for seven years. (含義:現(xiàn)在還住在肯塔基州,有可能指剛離去)

      注意: 用過去時表示現(xiàn)在,表示委婉語氣。

      1)動詞want, hope, wonder, think, intend 等。例如:

      Did you want anything else? 您還要些什么嗎?

      I wondered if you could help me. 能不能幫我一下。

      2)情態(tài)動詞 could, would。例如:

      Could you lend me your bike? 你的自行車,能借用一些嗎?

      3.一般將來時

      1) shall用于第一人稱,常被will 所代替。will 在陳述句中用于各人稱,在征求意見時常用于第二人稱。例如:

      Which paragraph shall I read first? 我先讀哪一段呢?

      Will you be at home at seven this evening? 今晚七點(diǎn)回家好嗎?

      2) be going to +不定式,表示將來。

      a. 主語的意圖,即將做某事。例如:What are you going to do tomorrow? 明天打算作什么呢?

      b. 計劃,安排要發(fā)生的事。例如:The play is going to be produced next month。這出戲下月開播。

      c. 有跡象要發(fā)生的事。例如:Look at the dark clouds, there is going to be a storm. 看那烏云,快要下雨了。

      3) be +不定式表將來,按計劃或正式安排將發(fā)生的事。例如:

      We are to discuss the report next Saturday.我們下星期六討論這份報告。

      4) be about to +不定式,意為馬上做某事。例如:

      He is about to leave for Beijing. 他馬上要去北京。

      注意:be about to do 不能與tomorrow, next week 等表示明確將來時的時間狀語連用。

      1)下列動詞come, go, arrive, leave, start, begin, return的一般現(xiàn)在時可以表示將來,主要用來表示在時間上已確定或安排好的事情。例如:

      The train leaves at six tomorrow morning. 火車明天上午六點(diǎn)開。

      When does the bus star? It stars in ten minutes. 汽車什么時候開?十分鐘后。

      2)以here, there等開始的倒裝句,表示動作正在進(jìn)行。例如:

      Here comes the bus. = The bus is coming. 車來了。

      There goes the bell. = The bell is ringing. 鈴響了。

      3)在時間或條件句中。例如:

      When Bill comes (不是will come), ask him to wait for me. 比爾來后,讓他等我。

      Ill write to you as soon as I arrive there. 我到了那里,就寫信給你。

      4)在動詞hope, take care that, make sure that等的賓語從句中。例如:

      I hope they have a nice time next week. 我希望他們下星期玩得開心。

      Make sure that the windows are closed before you leave the room. 離開房間前,務(wù)必把窗戶關(guān)了。

      2)一般過去時常與具體的時間狀語連用,而現(xiàn)在完成時通常與模糊的時間狀語連用,或無時間狀語。

      現(xiàn)在完成時的時間狀語:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不確定的時間狀語。

      共同的時間狀語:this morning, tonight, this April, now, already, recently, lately 等。

      3)現(xiàn)在完成時可表示持續(xù)到現(xiàn)在的動作或狀態(tài),動詞一般是延續(xù)性的,如live, teach, learn, work, study, know.。

      句子中如有過去時的時間副詞(如yesterday, last, week, in 1960)時,不能使用現(xiàn)在完成時,要用過去時。
