一年級學(xué)生英語語法【三篇】集合學(xué)習(xí)

字號:

正確的語法可以簡化信息,簡單的一句話就能傳達(dá)很多信息,甚至包含多重意思,就像雙關(guān)語一樣。語法正確還能避免歧義,明確指代關(guān)系和修飾對象等,是很有用的,學(xué)進(jìn)去了就明白了。以下是整理的相關(guān)資料,希望對您有所幫助!
     【篇一】
    一般過去時現(xiàn)在完成時主要用于:
    1 、表示到現(xiàn)在為止這一時期中發(fā)生的動作或情況,即多次動作的總和。
    e.g. We have learnt four English songs this month.
    How many times have you read the novel?
    For many days we haven`t seen each other.
    2 、表示對現(xiàn)在有影響的某一已發(fā)生的動作。
    e.g. The delegation has left 代表團(tuán)已經(jīng)走了(說明現(xiàn)在不在這里)
    Look, what you have done. 看你干的事。
    與這一時態(tài)連用的時間狀語有:
    already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語,連詞 since 引導(dǎo)的時間狀語從句。
    一般過去時與現(xiàn)在完成時的區(qū)別:
    一般過去時:重在說明動作在過去發(fā)生時的具體情況(時間、地點、方式、對象、細(xì)節(jié)等)。
    現(xiàn)在完成時:只提起已發(fā)生的動作(事實)及其影響,不說明動作發(fā)生時的具體情況。
    cf. Have you had your lunch?
    What did you have for lunch?
    I have ever been to the Great Wall,_and_I went there last summer with my father.
    注:現(xiàn)在完成時表達(dá)的動作常具有反復(fù)性,故下面一句是錯的:
    Have you seen the six thirty`s news program?
    應(yīng)改為:
    Did you see the six thirty`s news program?
     【篇二】
    過去進(jìn)行時主要用于:
    表示過去某個時刻或階段正在進(jìn)行的動作。
    e.g. At that time she was working in a PLA unit.
    那時她在解放軍某部工作。
    What were you doing this time yesterday?
    與這個時態(tài)連用的時間狀語常用:
    at nine o`clock, this time last night, these days, at that time 等。
    用 when 引導(dǎo)的時間狀語從句表示主句的動作正在進(jìn)行的時間。
    e.g. When he came in, I was reading a newspaper.
    注:
    1 、 while 引導(dǎo)時間狀語從句敘述過去的動作時,從句常用過去進(jìn)行時。
    e.g. I read a magazine while I was waiting for the bus.
    2 、 when 用作并列連詞,意為“這時”,連接兩分句時,第一句多用過去進(jìn)行時。
    e.g. I was reading a newspaper when he came in.
    一般過去時與過去進(jìn)行時的區(qū)別:
    一般過去時:強調(diào)過去某一時間開始或完成的動作。
    過去進(jìn)行時:強調(diào)過去某一時間正在進(jìn)行的動作。
    試區(qū)別下面兩句: We were building a reservoir last winter.
    去年冬天我們在修建一座水庫。(可能尚未建成) We built a reservoir last winter.
    去年冬天我們修建了一座水庫。(已經(jīng)建成)
     【篇三】
    一般將來時主要用于:
    表示將要發(fā)生的動作或情況
    e.g. Tom will have a bike of his own.
    與這個時態(tài)連用的時間狀語常用:
    tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
    一般將來時態(tài)與其它結(jié)構(gòu)表將來情況的區(qū)別:
    一般將來時態(tài) :主要從時間的角度表將要發(fā)生的動作或情況。
    be going to 結(jié)構(gòu) :①表(主觀上)打算或準(zhǔn)備做某事時。 ②表有發(fā)生某事的預(yù)兆時。
    e.g. They are going to have a competition with us in studies. It is going to rain.
    據(jù)以上區(qū)別,故下面一句是錯的:
    I am going to be eighteen years old next year.
    應(yīng)改為: I shall be eighteen years old next year.
    be about to do sth 結(jié)構(gòu) :意為“剛要做某事”、“馬上要做某事”強調(diào)時間之緊迫性。
    e.g. We are about to discuss this problem.
