15、w后永远不带a/an）.第二步：如果已经确定选what，那就继续观察形容词后的名词，名词是可数单数的，what后就带a/an,名词如果是复数或不可数的，what后就没有a/an。第三步：what后a/an的选用问题则根据“元an辅a”规律，也就是观察紧跟在a/an后面的单词读音是以元音或辅音开头。注意：如果考查题目中没有形容词而是有副词（大部分副词有ly 结尾），那肯定选how。选择填空。()1.He could _ basketball when hw was eight years old.A.play B.plays C.played D.playing()2.Could you rid
