I get upset. 我很生气。
That's so offensive. 真是令人生气。
offensive是“进攻的”, “进攻性的”意思，和defensive“防御的”, “防备的”是一对反义词。但是，这里的offensive是“冒犯的”，“无礼的”，“侮辱的”意思。offensiv作“进攻的”意思讲时，只在句中修饰名词。“她好像挺有进攻性的”，这句话用英文来说就是"She really seemed like an offensive girl". 但是，"She really seemed to be offensive"的意思却是“她好像很无礼”
That person is so rude. 那个人太粗鲁了。
How rude can you be?你怎么如此无礼？
