问题描述：
you had better drive carefully .the roads are wet
为嘛不能用would better
would better 咋不行啊
答
had better 为词组
答
因为这是固定搭配，
had better+动词原形， 表示“你最好...”
句意：你最好小心开车。路面是湿的 。
答
had better 是最好这佯做，有建议别人这佯做的意思。would better 用于你不应该做某事但事实上你已经做了这件事 而且该句型稍有命令的口气。
答
had better 你最好。。 固定搭配。
答
因为had better+动词原形
表示你最好...
习惯搭配,这里这个句子的意思是你最好小心开车,路面是湿滑的
如果是would情态动词的话,后面是要跟上动词的原形的,better并不是动词
