Hahah such a cute question!!! well,its a funny way to say that a person looks ugly^^ Saying like this,the person who you are talking about may not get angry...even laugh with u:D

If "grow" is what you're aiming for (as in: "He's growing impatient."), then "長得" is not what you want. "長得" involves actual growth and development, so glosses better as "grow (up) to be/into". For "He's growing/getting nervous/tense.", why not try "他越來越緊張." ?

如果我的朋友这么说，我会觉得他说话很幽默。这个人长得挺紧张的，耐人寻味。

我想到了 一句有意思的 长得太急了。。 形容那个人的脸看起来比实际年龄要大很多。。。。^ ^

你最好说在英语中bala。。bala。。。用普通话怎么表达对吗？ 在我理解你是问he looks serious. 汉语应该说 他看起来很严肃认真
