二分之一怎么打( 二 )


当我们要表示几十年时,可以拼写出数字,并小写 。比如:During the eighties and nineties, the U.S. economy grew.
如果想用不完整数字表达年代,就可以在倒数第二个数字前加撇号,数字后加s 。比如:During the '80s and '90s, the U.S. economy grew.也可以完整写出:During the 1980s and 1990s, the U.S. economy grew.
表示时间的数字通常是要拼写出来的 。比如: She gets up at four thirty before the baby wakes up. The baby wakes up at five o'clock in the morning.
当表明上午或下午(A.M. or P.M.),并强调时间时,通常用阿拉伯数字表示 。比如,The flight leaves at 6:22 A.M.再比如,She had a 7:00 P.M. deadline.
表示地址时可用数字表示 。比如,I lived for years at 4 Howitt Road in Belsize Park.
