1、數(shù)詞易錯(cuò)1. 確數(shù)和約數(shù)(1)當(dāng)說(shuō)“幾百”、“幾千”這樣一些確數(shù)時(shí),“百”、“千”是不能用復(fù)數(shù)形式的。結(jié)構(gòu)是:數(shù)詞+dred/thousand/million/billion+名詞復(fù)數(shù)如:fivedred 五百;three thousand 三千;two million 兩百萬(wàn);six billion 六十億。(2)當(dāng)dred,thousand,million 加上 s 后,它們就成了概數(shù),表示“數(shù)百”、“數(shù)千”、“數(shù)百萬(wàn)”等概念。而且通常接 of,表示“的”,“數(shù)以千計(jì)的”,“成千上萬(wàn)的”,“億萬(wàn)的”等。結(jié)構(gòu)是:dreds/thousands/millions/billions+of+名詞復(fù)

2、數(shù)。如:dreds of new tall buildings 數(shù)以百計(jì)的新高樓;thousands ofstudents 數(shù)以千計(jì)的學(xué)生;millions of people 數(shù)以百萬(wàn)計(jì)的人。2. 數(shù)詞和冠詞的關(guān)系(1)一般情況下,序數(shù)詞前要加定冠詞 the,但基數(shù)詞前不加冠詞。如:He failedhetry. 他第一次嘗試失敗了。My number is forty-nine.號(hào)碼是 49。(2)a/an+序數(shù)詞,表示“又一、再一”。如:The monkey ate a second banana.這只小猴又吃了一根香蕉。(3)of the+基數(shù)詞,表示“范圍”。如:You can ch

3、oose a toy of the two as a birthday present.你可以在這兩個(gè)玩具中選一個(gè)作為生日。3. “數(shù)詞+more”與“another+數(shù)詞”(1) 表“另外的”接復(fù)數(shù)名詞,如與具體數(shù)詞連用,則置于數(shù)詞之后,但與定冠詞 the 連用時(shí),other 要放在數(shù)詞前。如:Mr Smisked me to fetch another three CDs.先生讓我再拿三張 CD。(2) more 一般位于數(shù)詞之后名詞前,有時(shí)也可置于名詞之后。如:She has got five more pens.她還有五支鋼筆。(3) more 除跟數(shù)詞外,還可與 a little,a

4、 few,a lot,several 等詞連用,而且名詞也可以是不可數(shù)名詞。如:Id like to buy a few more books.再買(mǎi)幾本書(shū)。There are many more dictionaries on the desk.課桌上有許多詞典。Would you like some more tea?再喝點(diǎn)茶好嗎?提分策略英語(yǔ)中的數(shù)詞看似簡(jiǎn)單,實(shí)際上運(yùn)用時(shí)并不簡(jiǎn)單,有很多需要注意的地方。近幾年中考對(duì)數(shù)詞的考查主要集中在基數(shù)詞和序數(shù)詞的辨析用法上。日期、時(shí)間和分?jǐn)?shù)也是中考考查的考點(diǎn)。數(shù)詞考查往往與其他知識(shí)點(diǎn)考查結(jié)合進(jìn)行,如主謂一致等。正確解答數(shù)詞有關(guān)問(wèn)題,需要熟記基本詞匯,掌

5、握一定解題策略。1. 熟練掌握基礎(chǔ)知識(shí)在復(fù)習(xí)過(guò)程中,要系統(tǒng)歸納、數(shù)量掌握數(shù)詞的構(gòu)詞法以及各類(lèi)數(shù)詞的基本用法。特別是日期、時(shí)刻、分?jǐn)?shù)的表達(dá)形式。這樣解題才能得心應(yīng)手?！纠?1】(201429)Its never too old to learn.
