问题描述：
.The fire is very dangerous .It is very important ________ with fire
The fire is very dangerous .It is very important ________ with fire.
A.to careful B for careful C to be careful D be carefu
答
c,因为有一个句型是it is +adj+(for sb )of sb to do sth.是固定的
答
选C,to be careful 因为careful是形容词A不对，important 后需加不定式
答
选 C
It is +形容词 +to do sth 是固定句型.
to be careful with fire 小心火
意思是：火很危险.当心火是很重要的.
