B解析本题是考查enough的使用，在这道选择题中，首先应知道enough不存在任何形式的比较，故选项A、D不在选择之列。我们再看fast enough和enough fast，enough在句中，必须要放在所修饰的形容词或副词后面，特别是enough后面仍接有短语表示“足够……”时。例如：He is old enough to start school.他已到了上学的年龄。（修饰形容词）He works carefully enough.他工作相当细心。（修饰副词）This book is easy enough for me to read.这本书我读起来非常容易。（修饰形容词）This car runs fast enough to catch any train.这辆车开得这么快，足够可以赶上任何一列火车了。（修饰副词）
