2、d fly to you.He talks as if he were the boss.2出现在 Wish,would rather(宁愿) , suppose(假设) , imagine(设想)之后,表与事实相反(non-fact)I wish I were tall.Id rather I were not here.Suppose the earth were flat. be-型虚拟式be-型虚拟式中动词不论人称,均用原形;此种虚拟式不一定与事实相反 。主要用于以下几种情况:1 用于 if,though 等引导的句子中Eg. If the rumor be true, everyth
3、ing is possible. (如果这个谣言是真的,那么任何事都有可能。 )Though everyone desert (抛弃 ) you, I will not. (即使大家都抛弃你,我也不会)注:此种句子和 were 型虚拟式不同,were 型均为 non-fact(非事实) ,而此种表假设,并非明显的与事实相反。2 用于公式化的句子中Long live Peoples Republic of China!God bless you!Devil take him! (混蛋!)3用于命令,决定,建议等词语之后 注:此种虚拟式和一般意义上的虚拟不同,它并非 non-fact, 也没有假设
