11（）
A. grew with
B. agree with
C. coincide with
D. in concert with
参考答案：D
解析：
语义搭配题。in concert=in agreement意为“一致，共同”，如：The various government decided to act in concert over this matter. (各国政府决定对此事采取一致行动。)根据原文的句子结构，此处缺少一个词与后面的a virus or other agent一起作句子的状语，只有选项[D]in concert with(与…一致)可以与后面的构成介词短语，作状语，故选D。选项[A]grow with与句意不符；选项[B]agree with=be in accordance with意为“与…一致”，例如：Your story agrees with his in everything. (你的故事跟他的在各方面都一致。)虽然意思正确，但此处是句子的状语需要用agree的非谓语动词形式，故排除；选项[C]coincide with意为“(意见，观念等)恰好一致，相符合”，如：I timed my holiday to coincide with the children’s school holiday. 意思、结构都不符合。全句可译为：它看起来并不是细菌、病毒或真菌引起的，而是一种被称为朊病毒的蛋白质感染粒子引起的，它也许与病毒或其他的病源体共同引起了疯牛病。
