4、d to walking解析:根据题意可知，此题考查used to do(过去常常做某事)，be used to doing(习惯做某事)，故此题选D. 而be used to do 意为“被用来做”2. 反意疑问句 肯定陈述句否定提问如：Lily is a student, isnt she? Lily will go to China, wont she? 否定陈述句肯定提问 如：She doesnt come from China, does she?You havent finished homework, have you?提问部分用代词而不用名词 Lily is a student

5、, isnt she?陈述句中含有否定意义的词，如：little, few, never, nothing, hardly等。其反意疑问句用肯定式。 如：He knows little English, does he?他一点也不懂英语，不是吗？They hardly understood it, did they?他们几乎不明白，不是吗？注：反意疑问句的答语 如果反意疑问句中的陈述部分为肯定句时，用“Yes+肯定结构”作为肯定回答；用“No+否定结构”作为否定回答 - He enjoys singing , doesnt he? 他喜欢唱歌，是吗？ - Yes, he does. /No,
