1. Except for identical twins, each living thing has its own unique DAN. 除了每个双胞胎之外,每个生物都有他唯一的DNA。
1)except for除……以外,只是,排除的不是同类,表示对主要部分的肯定和对局部的否定。
Your article is quite good except for several spelling mistakes. 你的文章很好,只是有几处拼写错误。
except, besides, but 和except for 的区别
except “除……之外”,排除后面的人或物,而且排除的内容和主语往往是同一类。如:We went to see our teacher yesterday except Li Ming. 昨天除了李明以外我们都去看我们的老师了(李明没去)。
besides “除……之外,还有”,包括该词后面的人或物。如:We all went to see a film besides Li Ming. 除李明以外我们也都去看电影了(李明去了)。
but““除……之外”,一般用于否定句中,表示”只有……“,如:There is nothing but a pen in the pencil case.铅笔盒里除了一支钢笔之外什么也没有。
except for “除……之外”,后面排除的部分和主语不是同一类人或物.如 :The movie was good except for the ending.这部电影除了结局之外都很好。
