问题描述:
I happened ____ this book before.A.having read B.to have read C.read D.reading
答
B ,因为happen to 是偶然的意思,全句解释为我碰巧以前读过这本书
以前读了要有完成时所以CD不对
答
选择B,因为根据题目中的before一词,得知“我” 已经 (完成时)读过这本书,Be happen to do 是固定句式,意思是碰巧做过某事。综合以上,选B
答
B
答
选择B,happened to do 固定短语搭配。
I happened to have read this book before我之前碰巧有读过这本书
答
B
happen to do sth
固定搭配~
由于句子中有before,所以用have done的完成时~
答
b
happen to do sth,这里又是完成状态,所以用完成时
答
1.happen to do
2.before——所以是过去式或过去完成时。此句的汉语意思“曾经读过 ”对现在有影响,所以用完成时
