    1．【答案】D
    【解析】四個選項的意思分別是subside“下沉”；idealize“理想化”；initiate“發(fā)起”；sustain“支撐，撐住”。句意是：建筑物倒塌是因為它的地基不足以支撐整個建筑物的重量。所以正確答案是D。
    2．【答案】A
    【解析】A項radiation“輻射，放射線，放射物”；B項cancer“癌癥”；C項microwaves“微波”；D項high temperature“高溫”。題中講的是核電站，與之相對應的應該是核輻 射，故本題的答案為A。
    3．【答案】D
    【解析】A項mammoth“猛犸象，龐然大物”；B項penguin“企鵝”；C項mosquito“蚊子”；D項mammal“哺乳動物”。根據(jù)句子中所給的信息：誕生于母體，嬰孩時飲用母親的奶汁，這些都是哺乳動物的特征，本題中所填的詞代表這一類動物，所以A不對，B、C兩項所提到的動物不具有句子中所表達的物種特征，也不對。故本題的答案為D。
    4．【答案】C
    【解析】C項revenues“收入，國家的收入，稅收”符合題意。其他三項中，A項privileges“特權，特別待遇，基本公民權利”，B項efficiency“效率，功效”，D項、validity“有效性，合法性，正確性”，都與題意不符。本題是說市政計劃委員會說他們下一年度的財政前景是樂觀的。他們期望提高稅收。因此C項為正確答案。
    5．【答案】C
    【解析】C項session“會議，開庭”符合題意。其他三項中，A項convention“大會，協(xié)定，習俗，慣例”，B項 conference“會議，討論會，協(xié)商會”，D項assembly“集合，裝配，集會，集結，匯編”，都與題意不符。本題是說當明年春天議會再度開會時，污染問題和其他幾個問題將被討論。因此C項為正確答案。
