【篇三】
我們知道名詞可以分為可數(shù)名詞和不可數(shù)名詞，而不可數(shù)名詞它沒有復(fù)數(shù)形式，但可數(shù)名詞卻有單數(shù)和復(fù)數(shù)之分，復(fù)數(shù)的構(gòu)成如下：
一)在后面加s。如：fathers, books, Americans, Germans, apples, bananas
二)x, sh, ch, s, tch后加es。如：boxes, glasses, dresses, watches, wishes, faxes
三)1)以輔音字母加y結(jié)尾的變y為i再加es 如：baby-babies, family-families, duty-duties, comedy-comedies, documentary-documentaries, story-stories
