一、表语从句的考查
表语从句在句子中作表语,位于主句中的连系动词之后。
　　[考例1] - Are you still thinking about yesterday's game?
　　        -Oh, that's_______. (2003北京春季)
　　A. what makes me feel excited 　　
    B. whatever I feel excited about
　　C. how I feel about it 　　　　　 
    D. when I feel excited
　　解析: 本题全句意为：“你还在考虑昨天的比赛吗？” “哦，正是这件事使我激动不已。”关键词语“still thinking about yesterday's game”决定必然用表语从句what makes me feel excited, 表示比赛留下久久不能忘怀的印象, 现在还在thinking; B项是泛泛而指,当然不行; C和D项内容与上下文问题无关。故答案为A。
     [考例2] (2001上海春招) What the doctors really doubt is ______ my mother will recover from the serious disease soon.
　　 A. when 　　　B. how 　　　C. whether 　　 D. why
解析：本题题意为“医生真正怀疑的是我母亲是否将会从严重的疾病中恢复”。这里是表语从句，根据题意，故答案为C。
     [考例3] Perseverance is a kind of quality, and that's_______ it takes to do anything well.( 2002上海春季)
