Lesson Twelve B. Lesson Twelfth C. Twelfth Lesson D. the Lesson Twelfth 2)He is a student of ____. A. Class First B. the Class One *C. Class One D. First Class 考点二、分数表达法 分母用序数词，分子用基数词。如果分子大于一，那么分母的序数词要用复数形式，表示二分之一可以用a/one half，四分之一可以用a/one quarter, 有整数部分时用“整数+and+分数部分”。如： 1) He did it _____it took me. A. one—third a time B. one—third time C. the one--third time *D. one—third the time 点拨：D. it took me是定语从句，其前省略了关系代词that,因有定语从句限制，time之前应加定冠词，表示特指；one—third the time意为“三分之一的时间”。题意：他做此事所用时间是我的三分之一。 2) ______ of the land in that district _____ covered with trees and grass. A. Two fifth… is B. Two fifth…are *C. Two fifths…is D. Two fifths…are 点拨：C 点拨：当分子大于１，所以分母要用复数；“分数＋of＋名词”作主语，谓语动词应与名词保持人称和数的一致。 1/3 A/one third 2/3 two thirds two and two thirds 1/4 a/one fourth a/one quarter 3/4 three fourths three quarters ten and three fourths ten and three quarters 1/5 a/one fifth 2/7 two fifths three and two fifths 1/6 a/one sixth 5/9 five sixths twelve and three quarters 考点三、年代与几十几岁表示法 通常是把逢十的基数词用作复数形式, 表示年代的数词前用定冠词，表示岁数的数词前用形容词性物主代词。如： 1、表示年代的范例： 1） This story took place in the 1860s. 这个故事发生在十九世纪的六十年代。 2) It is
