问题 We used to swim in this lake, but now it is seriously ______.

选项 A、contemplated
B、contrived
C、corrupted
D、contaminated

答案D

解析 近义词辨析。这四个选项的词性都是动词,其中contemplate表示“注视;凝视;沉思;期望”,如:The young surgeon contemplated the difficult operation of kidney transplant.(年青的外科医生为肾移植这一棘手的手术苦思冥想。)contrive是指“发明,设计,图谋”,如:to contrive a new kind of engine (设计一种新的发动机);corrupt表示“使腐烂,腐蚀,使恶化”,如:The businessman was sent to prison for trying to corrupt a tax official with money.(他因企图向税务官员行贿而被判入狱。)contaminate表示“弄脏;污染”,如:The river was contaminated with waste.(这河水被垃圾污染了。)根据句意,河水被严重污染了,应该选择D)。
