新概念英語第1冊第123-124課重點(diǎn)語法

字號:

一、重要句型或語法
    1、定語從句
    當(dāng)句子用來充當(dāng)定語時(shí),這個(gè)句子就叫定語從句。學(xué)習(xí)定語從句先要理清兩個(gè)基本概念:先行詞和關(guān)系詞。先行詞是指定語從句所修飾的成分,而關(guān)系詞是指連接定語從句的連接詞,分為關(guān)系代詞和關(guān)系副詞兩大類。本課側(cè)重的是關(guān)系代詞的省略,以及定語從句改為短語的用法。如:
    They're people I met during the trip.
    That's the ship we travelled on.
    That's the man I told you about.
    The man standing behind the counter.
    The men repairing the road.
    二、課文主要語言點(diǎn)
    Look, Scott. This is a photograph I took during my trip to Australia. 1)句中的先行詞a photograph表物,在從句中充當(dāng)賓語,原本應(yīng)該用that或which,在句中為了簡便需要省略了。 2)take a photograph,拍照。。 3)trip to+地點(diǎn),到哪兒的旅行。
    Let me see it, Mike. 注意let的用法:let sb. do sth.,表示讓某人做某事。
    They're people I met during the trip. 先行詞people表人,在從句中作賓語,所以關(guān)系代詞原本應(yīng)該用who或whom,但為了簡便需要省略了。
    That's the ship I travelled on. 1)先行詞the ship表物,在從句中作賓語,所以原本要用關(guān)系代詞which或that,為了簡便需要省略了。 2)注意travel的過去式有兩種形式:英式為travelled,美式為traveled。
    What a beautiful ship! 可復(fù)習(xí)一下what和how引導(dǎo)的感嘆句的用法。本句話就相當(dāng)于:How beautiful the ship is!
    That's the man I told you about. 1)先行詞the man表人,在從句中作about的賓語,原本從句要用who/whom來連接,出于簡便需要省略了。 2)tell sb. about sth.,告訴某人某事。
    Remember? 完整形式為:Do you remember?
    The one who offered you a job in Australia. 1)先行詞the one表人,在從句中作主語,所以關(guān)系代詞采用了主格形式的who。 2)offer sb. sth.,給某人提供某物。
    It's not you, is it? 可講解反義疑問句的用法:前肯后否;前否后肯。
    I grew a beard during the trip, but I shaved it off when I came home. 1)grow a beard,蓄胡子。beard,一般只下巴上的胡子,絡(luò)腮胡;可拓展moustache(嘴唇上的胡子) 2)shave off,刮去。
    Why did you shave it off? My wife didn't like it! My wife didn't like it前面省略了because,這樣反倒加強(qiáng)了語氣,表達(dá)出了Mike的無奈。
    三、雙課補(bǔ)充內(nèi)容
    1、繼續(xù)操練關(guān)系代詞who/whom/that/which在定語從句的省略的用法。
    2、定語從句轉(zhuǎn)換為短語的用法。
