英语中时间的表达方式
1. 表示整点：时间+o’clock
Seven o’clock
2、如果分钟在半小时以内（包括半小时），表示“几点过几分”，句式为“分
钟+past+小时”。如：
eleven past seven
3、如果分钟在半小时以上（不包括半小时），表示“几点差几分”，句式为
“（60—分钟）+to+（小时+1）”，如：
two to seven
a quarter to eight
4、quarter意思是“四分之一”，用在时间中表示“一刻钟, 15分钟”。three quarter表示“三刻钟”即“45分钟”。不过，半小时可不是two quarter!而是“half”
a quarter past eight 八点一刻
half past nine 九点半
5、日常生活中用口语表达时间时，可以直接照书面数字读。如：
7:15读作seven fifteen
11:30读作eleven thirty
3:53读作three fifty-three
6、时间后面的am指上午；pm则指下午。
9.p.m 下午9点
5.a.m 上午5点
7、表达“在几点几分”，用at+时间。如：
My father begins to work at eight. 我的爸爸八点开始工作。
英语中日期的表达方式
（一）书写方面
先看下面的两个例子：
1. 1986年10月23日→October 23rd, 1986
2. 2002年1月17日→Ja nuary 17th, 2002
从上面的例子可以看出，英语日期的表达与汉语不同。英语表达的顺序为\"月、日、年\"。
（二）朗读方面
在朗读时，"月份"一般直接用英语读出；"日"则要读成"the + 序数词"；
读年份时，一般分为两个单位来读，前两个数为一个单位，后两个数为一个单位。如：1982年读作nineteen eighty-two, 1900年读作nineteen hundred。如果是三位数，先读第一位，再把后两个数合起来读。如：984年可读为nine eighty-four,757年读成seven fifty-seven。
另外，像2000年一般读成two thousand, 2001年则读成two thousand and one,以此类推，2004年应读成two thousand and four。
January 12th, 1993读成January the twelfth, nineteen ninety-three。
注意：
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
