Question

【题目】Mr. Smith—our English teacher, is said ________ to England for holiday last week.
A.to return
B.returning
C.to have returned
D.having returned

Answer 1

【答案】C
【解析】句意：Smith先生，我们的英语老师据说上周去英国度假了。It is said that...，“据说.......”，它可以转化成“主语+ is said to do sth.”结构。因此空白处应该使用动词不定式形式，另外return动作发生在say之前，所以这里用不定式的完成形式，故C项正确。
