Question

She is ten.这个句子是对的吗

Answer 1

个人感觉，口语这么说没问题，“她十岁”
不过写作最好写全句

Answer 2

主系表没错。
用英语表达一个人的年龄：　
1表示“整岁”,直接用基数词或year,age,例如“他20岁”可表示为：
He is twenty．
He is twenty years old．
He is a twenty-year-old man．
He is aged twenty．
He is at age twenty．
He is at the age of twenty．
He is twenty years of age．
2表示“在某人几十多岁”,用“in one‘s ＋基数词复数形式”,例如：
他七十多岁.He is in his seventies．（从70岁到79岁之间）
她五十多岁.She is in her fifties．（从50岁到59岁之间）
还可以借助early,middle,late来表达得更明确一些,例如：
那女孩今年二十二、三岁.The girl is in her early twenties．
他今年十四、五岁.He is in his middle teens．
她今年二十八、九岁.She is in her late twenties．
3表示“快满多少岁”用进行时或将来时,例如“他快满十八岁了”可说成：
He is getting on for eighteen．
He is going on eighteen years old．
He willbe eighteen years old．
It willbe his eighteenth birthday．
4表示“不满多少岁”,用副词barely,nearly,al- most,quite,yet,just等,例如“她不满十七岁”有以下几种说法：
She is barely ／nearly ／almost seventeen．
She is not quite ／yet seventeen．
She is just under seventeen．
5表示“差多久满多少岁”用介词off,例如：
他差5个月就满19岁了.He is five months off nineteen．
她再过3年就50岁了.She is three years off fifty．
6表示“超过多少岁”用介词past,例如：
他已年过50.He is past fifty．
他是一个过了中年的人.He is a man past middle age．
那孩子两岁零两个月.The baby is two months past two years old．
