半年好快英文

half a year

half a year 或者是a half year或者用连字符，即half-year是形容词，表示半年的如：经过半年的英语学习After a half-year study of English

半年 [词典] half a year; [例句]市场形势严峻，将导致今年上半年400个职位的削减。The tough market would lead to 400 jobs being cut in the first half of this year.

half （a）year~~~类似：half an hour半个小时a half and one hour一个半小时

half-year是形容词，表示半年的 half a year

semi-year不过我觉得一般不像咱们的习惯说半年，英语一般都说6个月。
