题目内容
9.Jack has already bought a new watch.(改为一般疑问句)Has Jack bought a new bookyet?
分析 句意:Jack已经买了一个新手表.Jack已经买了一个新手表吗?
解答 答案:Has…yet 根据题意,这是一个现在完成时的一般疑问句的改法:将have/has提到句首大写,将副词already(已经)改为yet,yet和already都是副词,表示"已经",但yet用于否定句和疑问句,且用在句子末尾;already用于肯定句.故答案为Has…yet.
点评 yet和already都是副词,都表示"已经"一类的意思,但yet用于否定句和疑问句,且用在句子末尾;already用于肯定句,在have或has后.如果要说"最近",就用recently.另外,yet还当连词用,与although是一组,且有although就只能加yet.
