题目内容
19.爱丽丝喜欢看赛马,但她从未骑过马.Alice enjoys watching horse races,but shehas never ridden a horse so far.
分析 has never ridden
解答 通过分析句子,可知本句缺少谓语,根据关键词so far结合语境可知此句应用现在完成时表达,表示到现在为止从未做过某事,强调对现在造成的影响;现在完成时的构成为has/have+动词的过去分词;"从未做过某事"表否定,应用否定副词never,对应的是have never done sth,由于主语she为第三人称单数,因而助动词为has."骑"为ride,过去分词为ridden.因此答案为:has never ridden.
点评 解答本题需注意过去分词的写法,并注意对时态的把握.
