新概念英語(yǔ)第一冊(cè)第117-118課重點(diǎn)語(yǔ)法

字號(hào):

第117-118課的內(nèi)容:
    一、重要句型或語(yǔ)法
    1、過(guò)去進(jìn)行時(shí)
    過(guò)去進(jìn)行時(shí)表示過(guò)去某個(gè)時(shí)刻或時(shí)段正在發(fā)生的事情,其形式為was/were doing。課文里出現(xiàn)了when和while引導(dǎo)的時(shí)間狀語(yǔ)從句和并列句的用法。如:
    When my husband was going into the dining room this morning, he dropped some coins on the floor.
    While we were having breakfast, our little boy, Tommy, found two small coins on the floor.
    二、課文主要語(yǔ)言點(diǎn)
    When my husband was going into the dining room this morning,
    he dropped some coins on the floor.
    1)注意when后面的謂語(yǔ)動(dòng)詞一般都用did,此處when的用法與while相同。 2)drop,落下。
    There were coins everywhere. everywhere,到處。
    We looked for them, but we could not find them all. 1)注意look for與find的區(qū)別,look for強(qiáng)調(diào)過(guò)程,find強(qiáng)調(diào)結(jié)果。 2)all在此表示全部的硬幣,用在句末,強(qiáng)調(diào)的是還有一些硬幣沒(méi)找到。
    While we were having breakfast, our little boy, Tommy,
    found two small coins on the floor.
    while引導(dǎo)的是并列句,其謂語(yǔ)動(dòng)詞一定要用進(jìn)行時(shí)。
    He put them both into his mouth. 1)put...into...,放入。 2)both在此起強(qiáng)調(diào)作用。
    We both tried to get the coins, but it was too late. both放在代詞主語(yǔ)we后面,起到強(qiáng)調(diào)作用,強(qiáng)調(diào)我們兩個(gè)人同時(shí)都想從Tommy手里搶回硬幣。
    Tommy had already swallowed them! 1)本句話的動(dòng)詞采用了過(guò)去完成時(shí)的時(shí)態(tài),可在下課里學(xué)習(xí)。 2)swallow,吞咽。
    Later that morning, when I was doing the housework,
    my husband phoned me from the office.
    1)later,后來(lái)。 2)do one's housework,做家務(wù)。 3)phone,打電話,相當(dāng)于call或telephone。
    Tommy's been to the toilet three times this morning,
    but I haven't had any change yet!'
    1)句中的three times是完成時(shí)的標(biāo)志,所以謂語(yǔ)動(dòng)詞采用了has been to的完成時(shí)態(tài)。 2)change在此有雙關(guān)的含義,一是表示零錢,二是表示變化。。
    三、雙課補(bǔ)充內(nèi)容
    操練過(guò)去進(jìn)行時(shí)的用法,尤其是when和while的用法。
