短语have a thing for someone喜欢某人(=be attracted to someone)，

例：I can tell by the way she looks at me that she has a thing for me.从她看我的眼神就能感觉到她对我有意思。再如：I have a thing for Jennifer Aniston. She’s so hot! 詹妮弗•安妮丝顿简直让我神魂颠倒。她太正点了！

类似短语：have a thing about someone/something不仅可指"喜欢某人/物"，而且还可指"讨厌某人/物"，具体要看上下文。

例如：1) She's got a thing about spiders - she won't touch them. 2) Elaine has a thing about strawberry ice cream. She can't get enough of it
