old one years

old one years 1岁时,是 one years old 还是 one year old? 一岁是one year old还是one years old? 急! years old怎么读,比如:one(万) Tina is 14 years old.Tara is 15 years old.改为合并句 Tara is one 请问,“一岁”翻译成英语是"one year old"还是"one years old"? 请问,我一岁了,用英语怎么说:one year old ,还是one years old Saran is 12 years(old,older).She is one year 改错 My sister is one years old than I. he is one ---- old .横线上填year还是years My uncle is 什么.He is twenty-one years old. “-year-old” “years old”
