名词转化为动词1. She gave me a glass f water.2. Yu shuld water the flwers twice a week.
形容词转化为名词1. She is wearing a black dress.2. The girl in black is very beautiful.
形容词转化成名词。如：cld adj.冷的→ back adj.后面的→quiet adj.安静的→ calm adj.平静的→
形容词转化为动词1. Tm is a brave man. 2. He always braves the difficulties .n life.
形容词转化成动词。如： （adj.更好的→v.改善） （adj.安静的→v.使安静） （adj.凉快的→v.冷却） （adj.空闲的→v.节省） （adj.自己的→v.拥有） （adj.亲密的→v.关闭） （adj.慢的→v.减慢） （adj.最后的→v.持续）
