10．Jack is teacher I've ever known．No one teaches better than him．（ ）| A． | a better | B． | a worse | C． | the worst | D． | the best |
分析 杰克是我所知道的最好的老师，没有人比他教得更好．
解答 答案：D 根据I've ever known可知，此处表示比较的范围是"我所知道的"，要用形容词的最高级；根据No one teaches better than him可知，要用形容词good最高级形式是best，并且形容词最高级前要加定冠词the，意思是"最好的"，故选D．
点评 判断形容词或副词的比较级和最高级，主要是看几者之间的比较．两者之间用比较级，三者或三者以上比较用最高级形式．本题是三者以上之间的比较．
