2024屆高考英語二輪語法強攻課件:數詞
數詞主要包括基數詞、序數詞和分數詞。基數詞是表示數目多少的數詞,序數詞是表示先后順序的數詞。分數詞由基數詞和序數詞構成。 一、基數詞
1. hundred, thousand, million, billion, dozen, score等前有具體數字或several, a few等修飾時,一般不用復數;在表示不確切數目時,可用復數。如:
Several million people in the world are using this brand of toothpaste every day.
My teacher went to the bookstore and bought dozens of books.?
2. 表示年歲時,用“in one’s +逢十的基數詞的復數”。如:in his forties。
3. 表示年代時,用“in the +逢十的基數詞的復數”。基數詞的復數若用阿拉伯數字表示,可直接加s,也可加’s。如:in the 1950’s / 1950s。 二、序數詞
1. 序數詞前通常要加定冠詞the或與物主代詞一起使用,在句中可作主語、賓語、定語和表語等。
2. 序數詞前也可加不定冠詞,表示“再一,又一”。如:a third time, a third and a fourth等。 三、分數詞
1. 分數詞是由基數詞和序數詞構成,分子用基數詞表示,分母用序數詞表示;除了分子為1的情況下,序數詞都要用復數形式。如:1/3 one third;3/5 three fifths。
2. “分數/百分數+ of +名詞/代詞”作主語時,謂語動詞的數與名詞或代詞的數保持一致。如: Two-thirds of her spare time is spent on housework. 80 percent of the houses were damaged in the big earthquake. 四、常見考點
高考對數詞的考查主要集中在年齡表達法、年代表達法、序數詞前加冠詞及數詞作主語時的主謂一致等。 【考例】One-third of the country _______ covered with trees and the majority of the citizens _____ black people.?
A. is; are ?????? ????????????????? B. is; is C. are; are ? ? ? ? ? ? ? ? ? ? ? D. are; is
