九. 英语日期的表示法
英语中月份和星期名称都是专有名词,它们的首字母必须大写,并且前面无需用冠词。
用英语表示日期,其顺序为 月+日+年,日和年之间需用逗号隔开。如:August 2nd,2003(2003年8月2日)。也可以用日+月+年来表示。如:10th May,2003(2003年5月10日)。英语日期前介词的使用:若指在哪一年或哪一月,则用介词in,若具体到某一天,则需用介词on。如:
①She was born in 1989
②She was born in August.
③She was born in August 1989.
④She was born on 2nd August, 1989.
十. 名词单数变复数
01
在英语里面,名词分可数名词(countable noun)和不可数名词(uncountable noun)。不可数名词没有单复数之分,用时只当单数词用;可数名词有单复数之分,一个的前面要用a或an,eg: a pencil, a basketball, a dictionary, an egg, an ID card,而复数即两个或两个以上的要作相应的变化,情况如下:
(1)一般的词在单数词后直接+“s”
book→books,pen→pens,car→cars,map→maps,cartoon→cartoons
(2)以s,x,sh,ch结尾的词+“es”
box→boxes,watch→watches
(3)以辅音字母+y结尾的名词去掉“y”,改成“i”,再加“es”
family→families,comedy→comedies
(4)以f或fe结尾的词,先去掉f或fe,改成“v”再加es
knife→knives,
wife→wives,
handkerchief→handkerchieves
(5) 特殊词,特殊变化,需单独记:
child→children,man→men,foot→feet,woman→women
tooth→teeth,sheep→sheep,deer→deer
