Thanks for your help. It’s really nice of you.
[解析] 该句式还可扩展为It’s (That’s ) + adj. + of sb. + to do sth.。这类形容词有nice, good, kind, clever, right等。如：
That’s very kind of you to say so.谢谢您这么说。
注意：表示性质、品格、品德之类的形容词，后面的介词用of.其他的形容词（表示大小、方位、形状等普通形容词）多用for或者to. 例如：
The sun is far for us to see. 太阳看上去离我们太远了。
It is very easy for me to do so. 这样做对我来说太容易了。
8. With the medicine box under her arm. Miss Zhao hurried off to look after the man. 赵老师腋下夹着药箱匆忙赶去照顾那个男的。
With the medicine box under her arm是介词短语作伴随状语。With在此意为“夹着”，它和其后的名词或代词构成介词短语，表示附带情况。如：
A woman looked worried, with a child in her arms.一个女人抱着个孩子，显得很着急。
He likes sleeping with the window open．他喜欢开着窗户睡觉。
With the light on, we began to work again．灯亮了以后，我们又开始干了起来。
With these words, the tiger jumped into the river．说着这些话，老虎跳进了河里。
另外，“with +名词”这一结构在句中可作后置定语。如：
China is a country with a long history.中国是一个历史悠久的国家。
