题目内容

3．______ the teachers in the school is one hundred，and ______ of them are women teachers．（　　）

	A．	A number of； four fifth		B．	The number of； four fifth
	C．	A number of； four fifths		D．	The number of； four fifths

分析这个学校老师的数量是100人，其中五分之四的是女教师．

解答答案：D．the number of表示"…的数量"，跟复数名词连用作主语时，中心词是number，谓语动词要用单数，a number of表示"许多"，相当于 many，修饰可数名词复数．作主语时，谓语动词用复数．因前半句的谓语动词is是单数，A和C是必须要排除的．英语分数，分子读坐基数词，分母读做序数词．如果分子是一，则分母直接读做序数词；如果分母大于一，则序数词要加s变成复数，4/5的正确表达应是four fifths，B应在fifth后加s．只有D两个条件都符合，故选D．

点评本题考查the number of的用法和分数表达法，强调两点1．the number of表示"…的数量"，跟复数名词连用作主语时，中心词是number，谓语动词要用单数．2．分数的正确表达分母大于一，则序数词要加s变成复数．
