flow的过去式和过去分词是flew flown吗？

这是我们老师说的，我深表怀疑，字典上的和老师说的不一样，到底是什么啊？我的字典是新华书店买的，应该不会有错的才对啊，帮帮我啊．

flow flows flowing flowed flowed

fly flies flying flew flown

老师不对

没错

flew flown是fly的过去式和过去分词

不对,应该是flow-flowed-flowed fly-flew-flown 老师有时候一马虎也容易出错的.

老师错了 是 flow-flowed-flowed

词根： flow流，漂，飘动，流动to flow, float 动词 v. （河水等）流动 move like water · That river is flowing very fast. 那条河流得很快。 · The river flows eastward into the sea. 河水东流入海。 动词 v. 流畅 move or spring forth smoothly or continuously · The lines in this painting flow. 这幅画的线条很流畅。
