参考答案:D进入在线模考
【译文】老年人和年轻人存在沟通上的问题是普遍的。
【解析】考查there be句型以及it is(un)common to do句型的用法。如果there be结构中的动词be要用不定式.则其逻辑主语there要用for引导,形成for there to be sth.结构,表示“有”或“存在”某种情况。如:It was too late for there to be any buses.此外.there be还可以作介词0f,about的宾语,用there bein9的形式.如:No one had told Smith about there being a lecture the following day.因此选D。
