_,and I can do it better.A given more time B more time 选哪个?还有一道题：One more step_ I will

One more time,and I will do it better.这是正确的.
问题在and上,前后都是简单句,中间就用and.
= If I am given one more time,I will do it better.
Given more time,I will do it better.
Given more time = If I am given more time,
所以 and 在此不能用.
