19、 prefer to fly 我宁愿乘飞机也不愿乘船。,这两个结构后面带名词时情况也一样： 例: Would you like some gin？ Id prefer a coffee=Id rather have coffee than gin,would rather/sooner和would prefer后面都可跟完成式，但后者带to。 例: We went by sea but Id rather have gone by air=Id prefer to have gone by air (我愿意乘飞机去，可我的愿望未能实现） 这和 would like+不定式的完成式有点相似,would like+带to 的不定式的完成式也表示未能实现的愿望。,
