How about going for a drink together?
一起去喝一杯怎么樣？
What time shall we go?
我們什么時間去？
Well, you can hook me up, maybe?
嗯，也許你可以幫我介紹一下？
"hook up"是"connection"的意思，相當于中文里的介紹、認識之類的詞，并不單指男女之間的認識。比如某人正在找份工作，他的朋友剛好有人認識。他就可以跟這位朋友說"Hey! Since you're a friend of Tom, why don't you hook me up?"（嘿！既然你是湯姆的朋友，幫我介紹一下吧！）
I heard that he is already seeing somebody.
我聽說他已經有了交往的對象了！
美國人關于交友的用詞和我們有些不同。這里的"he is seeing somebody"有可能指他剛開始和某人交往，也可能指他和對方已經交往了一陣子。還有一個美國人常用來形容他們的感情狀況的詞是"relationship"。
They broke up last week.
他們上個星期分手了。
"break up"是“關系中止”的意思，不限于男女之間的關系。"break-up"是分手的名詞形。如:"They had an ugly break-up."（他們很不愉快地分手了。）
I'm dating her.
我正在跟她約會喔！
和某人約會除了用"date"，還可以用"romance"這個字。比如:"A and B have been dating for years."可以說成:"A and B have been romancing for years."，均為A和B愛情長跑多年的意思。注意名詞的"date"和"appointment"不可混用。"appointment"是男女以外的約會，如醫生、工作面談的約會。
