这道题选 B

B careless 是修饰you的 故选择of,但是如果形容词是修饰it形式主语所指代的事情时，就用for。

It’s very kind of you to help me. 你能帮我，真好。
It’s clever of you to work out the maths pro...

答案：B
理由：①若形容词是描述不定式行为者的性格、品质的，如kind，good，nice，right，wrong，clever，careless，polite，foolish等，用of sb.。
It’s very kind of you to help me. 你能帮我，真好。
It’s clever of you to work out the maths problem.
你真聪明，解出了这道数学题。
若形容词仅仅是描述事物，不是对不定式行为者的品格进行评价，用for sb.，这类形容词有difficult，easy，hard，important，dangerous，（im）possible等。
It’s very dangerous for children to cross the busy street.
对孩子们来说，穿过繁忙的街道很危险。
It’s difficult for us to finish the work. 对我们来说，完成这项工作很困难。

故第一空应填of

②so sb do意为“某人的确做了某事”
而so do sb意为“某人也做了某事”
