第1题：

（50）These processes of particle creation and destruction had been predicted from Dirac’s theory before they were actually discovered in nature, and since then they have been observed millions of times.


正确答案：
译文：粒子生成和毁灭的过程在真正被发现之前，迪拉克的理论已经对它们作出了预测，从那时起人们对此做过数百万次的观测。

本体考核知识点：状语从句、被动语态的译法。

该句由两个并列的分句构成：These processes had been predicted和since then they have been observed。前一分句中of particle creation and destruction部分是介词短语作定语，修饰主语processes，应译为“粒子生成和毁灭的过程”。Before...in nature部分为时间状语，翻译时，可按照汉语习惯前置，译成“在．．．之前”。后一分句中的时间状语since then可译成“在．．之后”或“从那时”。此外翻译被动语态结构had been predicted from Dirac’s theory时，为了突出施动者，可以按照汉语习惯，译为主动结构。

词汇：creation and destruction“生成和毁灭”。predict“预测，预言”，文中谈论的是科学现象，应该译为“预测”。in nature“实际上”。

第2题：

［A］ muted ［B］ discovered ［C］ doubled ［D］ undervalued


正确答案：A

本题考查动词辨析。空格处填入的过去分词与is构成被动式的谓语，因此其动词的实际的宾语是the might（强大力量，威力）。mute意为“消除或减弱声音；减弱，缓解”，如：mute the traffic noise/the criticism（减弱了车辆的噪音/委婉地提出批评）。discover意为“发现，发觉”；double意为“加倍”；undervalue意为“低估...之价值，看轻”。因此［A］符合文意，它与the might搭配，表示“威力减弱”。
