六岁半英文怎么说

He is six years and 6 months old.He is six and half years old.He is half a year to seven.He is a six-and-half-year-old boy.注意用法：six-and-half-year-old一般放在名词前，而且year用单数。汗，下面怎么还有人照抄？要知道英语的顺序也是从左到右理解的， half six 是3 的意思，另外也没有half six years old,这样用，没有任何理由。

I am six years old.I am six.I am at the age of six.I am six years of age.I will turn six next week.

举例来说吧：一岁半：one and half years old十岁半：ten and half years old但是，外国人很少这样表达的，若表达七岁半一般为more than seven years old.或者当强调小于某个年龄时，用less than ...years old 或者当强调只不过是某个年龄时用rather than ...years old

He is six years and 6 months old.He is six and half years old.He is half a year to seven.He is a six-and-half-year-old boy.He is six point five years old.

half six six and a half years old错了，应该是half and a six，sorry，好久没看英语都忘记了。一般口语不太正式的话这种说法是可以的
