B.didn’t die C.hadn’t died
D.wouldn’t have died 解析: 考查虚拟语气。下句意为:如果下了一点雨的话,现在的情况会好些,并且我种的蔬菜也不会死了。表示对过去情况的假设,从句谓语动词用“had done”,主句谓语动词用“would/could/should have done”。 答案: D Having killed up to 50 million people in 18 months,with a tendency to strike the young and fit rather than the old,the Spanish Flu is believed to have been the most acute epidemic in history. 西班牙流感在18个月内使多达5千万人丧命,并且发病的倾向为:年轻力壮的而不是老年人容易发病,它被认为是历史上最严重的流行性传染病。 本句中Sb./Sth.be believed to do=It’s believed that...意思为“……被认为是……”。类似的动词还有hope/report/think/announce等。但要注意:当不定式动作发生在谓语动词动作之前时,不定式要用完成式;强调不定式动作正在进行时,不定式要用进行式。 ①The book is said to have been translated into several foreign languages. =It is said that the book has been translated into several foreign languages. 据说这部书已被翻译成几种外文。 ②The banks are widely believed to be planning a cut in interest rates.人们普遍认为银行正在计划降低利率。 ③The next World Cup is reported to be held in Brazil. 据报道,下届世界杯将要在巴西举行。
