应该是百度翻译的吧、这样说不对的(1.没有主语补it 2.have done完成时like改liked
（改完直译）看上去我喜欢上了你：It seems that i've already liked you
但是我感觉这样说不是很地道,因为like不是瞬间动词,也许应该改成
1.看上去我爱上了你：It seems that i've already loved you
2看上去我和你坠入爱河了：It seems that i've already fell in love with you
一定要用like you的话就是：看上去我喜欢上了你It seems that i like you
