在看Kristy's Great Idea:
I thought about Sam. Now, he is pretty goodlooking with dark curly hair and sparkly blue eyes and a few freckles, but he was wearing jeans so ratty he’d once promised Mom he’d throw them away (but then hadn’t been able to go through with it), and a T-shirt that said: I KNOW YOU ARE, BUT WHAT AM I? To top it off, he was mad.
请教but then hadn’t been able to go through with it是不是“此时还没来得及扔”的意思?
Q2. 请教To top it off是什么意思?
