初中英語專題訓(xùn)練題:數(shù)詞部分

2010-05-14 14:50:23  來源:智康教育 文章作者:匿名

  先進(jìn)部分:知識(shí)點(diǎn)分析


  一、基數(shù)詞


  1)基數(shù)詞讀法: 年,月,日,時(shí)刻的讀法,如2007年六月十三日讀作:June (the) thirteenth, two thousand and seven


  (主要體現(xiàn)在口語診斷和聽力題目中)


  2)表示一個(gè)具體數(shù)字時(shí),hundred, thousand, million, billion一律不用復(fù)數(shù);在表示一個(gè)不確定數(shù)字時(shí)則用復(fù)數(shù)。例如:


  There are three thousand students in our school.


  After the war, thousands of people became homeless.


  3)在一些表示"一排"或"一組"的詞組里;


  如:They arrived in twos and threes. 他們?nèi)齼蓛傻牡竭_(dá)了。


  4)表示"幾十歲", 例如:He died still in his forties.


  5)表示"年代",用 in +the +數(shù)詞復(fù)數(shù);


  二、序數(shù)詞


  1)序數(shù)詞主要用作定語,前面要加定冠詞,例如:


  The first truck is carrying a foot baskets.


  2)序數(shù)詞有時(shí)前面可加不定冠詞來表示“再一”,“又一”這樣的意思,例如:


  We'll have to do it a second time.


  3) 注意較為容易拼寫錯(cuò)誤的序數(shù)詞及其縮寫形式:one---first, two---second, three---third, five---fifth, eight---eighth, nine---ninth, twelve---twelfth。


  縮寫形式:first→1st second→2nd third→3rd fourth→4th twenty-second→22nd


  4) 表示分?jǐn)?shù)時(shí),分子用基數(shù)詞表示,分母用序數(shù)詞表示。分子大于1時(shí),分母加-s。例如:


  three fourths, one second, two fifths


  2、難點(diǎn)?


  倍數(shù)表示法


  主語+謂語+倍數(shù)(或分?jǐn)?shù))+ as + adj. + as


  I have three times as many as you. 我有你三倍那么多。
