答案

11.B(year after year,表示正在进行发生的趋势)
12.A(have sth.to do )
13.D(worry about,固定短语搭配,be nothing to do)
14.A(正在进行发生的事,句子中的主语technology与谓语动词develop不存在被动)
15.A(被动语态,当主语与从句的主语一致时,省略从句主语I'm be )
16.(后置定语,last week,过去式,选B)
17.C(keep sb./sth.from (doing) sth,这里用被动语态表示处于没有危险之中)
18.B(首先是非谓语,再者river与动词flow之间不存在被动,故选A)
19.A(被动语态做后置定语)
20.D(句子从意思上说本身存在一个先后关系,其次主语preparations与动词complete又存在被动关系,根据后半句谓语动词are来断,时间段为到现在为止,所以用现在完成被动时)
