1.[谜底]B
[译文]一段时刻以来，世界首脑都一向指出有需要就裁军问题告竣共识。
[谜底解析]从该句中的时刻状语for some time now可以看出，主句的动作从曩昔某一时刻起头一向持续到此刻，而且动作可能还会延续，故应该用此刻完成进行时。
2. [谜底]D
[译文]Mr.White在化工进出口公司工作，但他休假时代为工业博览会工作。
[谜底解析]此刻进行时暗示现阶段正在进行的动作，也可以暗示一种姑且或今朝的状况，是以按照语境，应该用此刻完成时。
3.[谜底]C

[谜底解析]从该题的第一句语义可知“叛变”发生不止一次，尽管行为发生在曩昔，但结不美观是此刻仍然处于“叛变”的气象，是以用此刻完成时，暗示某事虽由曩昔起头，但与此刻还有关系。按照虚拟语气轨则，该题第二句的it's high time要求后面接得从句谓语动词要用一般曩昔时。
4.[谜底]B

[译文]因为被褫夺了连结自力的经济来历，Thomas Edison 不得不去当夜间电报员。
[谜底解析]该句后半句是一句完整的句子，那么逗号前的句子应该是一个分词自力结构作状语，deprive of 与其逻辑主语Thomas Edison 之间为被动关系，故用deprived of。
