It is important you to get there on time.

A. of

B. to

C. that

D. For

答案：

A. of

B. to

C. that

(答案→)D. For

解析：句意：对你来说按时到达那里是很重要的。对于It is+adj+to/for sb to do sth句型中介词to和for的选择要遵循的原则就是：当形容词为描述事物的性质时，如important，necessary，helpful和meaningful等用介词for，表示对某人来说做某事是怎么样的；当形容词为描述人的品质时，如kind，nice，stupid等用介词of，表示某人做某事所体现出来的品质。故选D。
