the number of跟a number of的区别

a number of… a number of…意思些若干（= some）接数名词复数或代词谓语动词用复数形式 a number of…词组还加入形容词表示数量大或小等（例：a large/small number of…许多/少数……） 注意和the number of区别the number of…意思……数字/数目介词of同其名词构成介词短语修饰the number.当作主语时谓语动词用单数例： Many people took part in 10,000-metre race, but only a number of them kept on running to the end. 许多人参加了10000米跑只有些人坚持跑底 A number of my friends think I should take a holiday. 我些朋友认我应该休假 The number of students is about twenty. 学生人数大约20人左右

the number of 后面加数字，表示多少的数目，谓语动词用单数，而a number of 是大量许多的意思，相当于many a lot of后接名词复数，谓语动词也用复数，而不是三单，亲 懂了吗？
