30. in gardening and volunteering work,Mrs.Black leads a busy and rich life at her old age.
A.Employed B.Employing
C.To employ D.Being employed
答案:A
解析:“Mrs.Black”和“employ”是被动关系,且表示一般情况,因此用过去分词作状语。
31.The traditional approach with complex problems in our studies is to break them down into smaller,more easily managed problems.
A.to deal B.having dealt
C.to dealing D.being dealt
答案:C
解析:approach与介词to连用,to后接动名词,表示“做某事”。
32.The fact that so many people still smoke in public places that we may need a nationwide campaign to raise awareness of the risks of smoking.
A.suggest B.suggests
C.suggested D.suggesting
答案:B
解析:考查动词时态。分析句子结构可知,主语是the fact,其后的that引导的是同位语从句,因此主句的谓语动词应用第三人称单数形式,结合上下文时态可确定,此处用一般现在时。
