laborer set a fire that caused $400 million damage to a
nuclear-powered submarine because he had anxiety and
wanted to get out of work early.
Example: He resigned his commission to take up civilian job.他辞去奎职儿从事平鸟工伧。
Example: The frigate rammed the submarine.护卫舰撞击了潜艇。
Example: A small, portable lamp usually powered by batteries.手电筒一种通常用电池供电的小型便携式电灯。
