Hayley教口語，“樣樣精通，樣樣稀松”用英語怎么說？

saying

Jack指一個(gè)人。Jack of all trades是在夸這個(gè)人多才多藝，好像什么都會。這個(gè)詞組的第一部分剛開始是在16世紀(jì)使用的，并且是用來贊揚(yáng)某人。慢慢地從18世紀(jì)開始，隨著master of none的加入，這個(gè)詞組的意思就慢慢不再表示夸獎(jiǎng)了。

said about someone who is able to do many things, but is not an expert in any

博而不精的人;萬金油;三腳貓

He seems to know almost everything, no wonder he is referred to as a jack-of-all-trades and master of none.

他似乎對所有的事情都知曉，難怪人們稱他為萬事通，但其實(shí)他樣樣不精。
