题目内容
11．He had ，but he didn't write ．（ ）| A． | enough time； careful enough | B． | enough time； carefully enough | ||
| C． | enough time； enough careful | D． | time enough； enough carefully |
分析 他有足够的时间，但是他写的不是足够细心．
解答 答案：B，
考察enough辨析．句子包含两个修饰成分，一个是"足够多的时间"，另外一个是"足够细心"，enough作为形容词修饰名词时，一般位于名词之前，又因为enough修饰副词时，一般位于其后，这里write是个动词，修饰动词应该用副词形式carefully．故选B．
点评 考察enough的使用，应根据具体的句子含义及固定搭配加以分析后选择．
