单句语法填空/单句改错
1.(2018·全国卷Ⅲ)I'm not sure________ is more frightened, me or the female gorilla (大猩猩) that suddenly appears out of nowhere.
解析:who 分析句子成分,空格处作从句的主语,根据后面的"me or the female gorilla"可知,作者把自己和大猩猩作对比,表示"我不知道我和大猩猩谁更害怕",故填who。
2.(2018·北京高考改编)This is ________ my father has taught me - to always face difficulties and hope for the best.
解析:what 句意:这就是父亲教给我的--永远面对困难并且寄予最大的希望。表语从句中动词taught缺少直接宾语, 且表示"......的东西",故填what。
3.(2018·北京高考改编)Without his support, we wouldn't be________ we are now.
