【长难句英译汉】
1. Every camera we sell comes with a two-year guarantee.
1.D
【句意】这些申请表应尽早地寄回，这很重要。
【解析】语法结构——虚拟语气。由“在It is essential that+从句的结构中从句用should+动词原形且should可以省略”以及句中“application forms”和“send(其动词过去分词为sent)”之间是被动关系可知D项”“be sent”正确。
2.A
【句意】你们可以指责我胆小，但是我仍然不情愿参加这场不受欢迎的战争。
【解析】名词和形容词词义辨析。cowardice“怯懦;胆小”;promiscuity“乱交;混乱”;provocative“挑衅的;煽动性的;激起争端的”;infidelity“(夫妻或伴侣间的)不忠行为;通奸”。由句中关键词“accuse指责”与“but I am still reluctant to fight in this unpopular war但是我仍然不情愿参加这场不受欢迎的战争”的对应知“胆小”符合语境，故A项正确。
