题目内容
15.It takes my mum two hours to do the housework today.( 划线部分提问 )Howlongdoes ittake your mum to do the housework today?
分析 --今天我妈妈花了两个小时做家务.
--你妈妈今天花多长时间做家务?
解答 答案:How long does;take.考查划线部分提问.根据two hours两小时,可知,对花费一段时间做某事提问,用疑问词组how long多长时间,剩下的变为一般疑问句,根据takes第三人称单数,可知是一般现在时态,主语是it第三人称单数,含有实义动词,变一般疑问句用助动词does,实义动词变原形take.答案是How long does;take.
点评 对划线部分提问,要根据划线部分内容选择合适的疑问词,剩下的变为一般疑问句.注意区分疑问词的用法.会正确运用一般疑问句用法.
