是she is an eight-year-old girl对 数字与名词组成的复合形容词用‘-’连接,名词不能加S。意思是:她是一个8岁的女孩。 这句话等于 She is eight years old . 加油!不明白再问!如果帮到你,请采纳,谢谢!noh_sslw_66|三级 都对。 只是用了连词符后 名词不用变复数了。 加连词后就等于把几个词变成了 一个形容词,...
she is an eight-year-old girl对 因为有了连字符,这个eight-year-old就相当于一个形容词,可修饰 girl了 而she is an eight years old girl可改为She is a girl at the age of eight. 不懂可追问,满意请采纳
