1．【答案】D
【解析】四個(gè)選項(xiàng)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?yàn)樗牡鼗蛔阋灾握麄€(gè)建筑物的重量。所以正確答案是D。
2．【答案】A
【解析】A項(xiàng)radiation“輻射，放射線(xiàn)，放射物”；B項(xiàng)cancer“癌癥”；C項(xiàng)microwaves“微波”；D項(xiàng)high temperature“高溫”。題中講的是核電站，與之相對(duì)應(yīng)的應(yīng)該是核輻 射，故本題的答案為A。
3．【答案】D
【解析】A項(xiàng)mammoth“猛犸象，龐然大物”；B項(xiàng)penguin“企鵝”；C項(xiàng)mosquito“蚊子”；D項(xiàng)mammal“哺乳動(dòng)物”。根據(jù)句子中所給的信息：誕生于母體，嬰孩時(shí)飲用母親的奶汁，這些都是哺乳動(dòng)物的特征，本題中所填的詞代表這一類(lèi)動(dòng)物，所以A不對(duì)，B、C兩項(xiàng)所提到的動(dòng)物不具有句子中所表達(dá)的物種特征，也不對(duì)。故本題的答案為D。
4．【答案】C
【解析】C項(xiàng)revenues“收入，國(guó)家的收入，稅收”符合題意。其他三項(xiàng)中，A項(xiàng)privileges“特權(quán)，特別待遇，基本公民權(quán)利”，B項(xiàng)efficiency“效率，功效”，D項(xiàng)、validity“有效性，合法性，正確性”，都與題意不符。本題是說(shuō)市政計(jì)劃委員會(huì)說(shuō)他們下一年度的財(cái)政前景是樂(lè)觀的。他們期望提高稅收。因此C項(xiàng)為正確答案。
5．【答案】C
【解析】C項(xiàng)session“會(huì)議，開(kāi)庭”符合題意。其他三項(xiàng)中，A項(xiàng)convention“大會(huì)，協(xié)定，習(xí)俗，慣例”，B項(xiàng) conference“會(huì)議，討論會(huì)，協(xié)商會(huì)”，D項(xiàng)assembly“集合，裝配，集會(huì)，集結(jié)，匯編”，都與題意不符。本題是說(shuō)當(dāng)明年春天議會(huì)再度開(kāi)會(huì)時(shí)，污染問(wèn)題和其他幾個(gè)問(wèn)題將被討論。因此C項(xiàng)為正確答案。
