35、 Li would rather not listen to rock music. 李先生不愿意听摇滚音乐。If youd rather be alone, well all leave here. 如果你宁愿独自呆着，那我们都离开这儿。Hed rather work in the countryside. 她宁可到农村去工作。You would rather stay at home and do some reading this evening. 今晚你最好呆在家中读点书。二、如果在两者中进行取舍，表示“宁愿而不愿，与其宁可”的意思时，则可用would ratherthan或would

36、rather than的句型例 I would rather watch TV at home than go to the cinema. 我宁可在家看电视而不愿去看电影。The children would walk there rather than take a bus. 孩子们宁愿步行去那里而不愿乘公共汽车。请注意 1） would ratherthan/wouldrather than也可以颠倒为：rather thanwould。Would(rather)和than后都接不带to的动词不定式，若选用的动词相同，那么than 后的动词可以省略。例 I would rather ha

37、ve noodles than rice. 我宁愿吃面条也不吃米饭。He would rather drink wine than beer 他喜欢喝红葡萄酒而不喜欢喝啤酒。Rather than work in such bad condition, he would give up. 与其在这样差的条件下工作，他宁愿放弃。2)使用would ratherthan句型时要注意“平行结构”，即在than 的前后要用两个同类的词或词组，如两个名词、两个不定式、两个介词短语等。例 I would rather go to work by bike than by bus. 我宁愿骑自行车也不愿乘公

38、共汽车去上班。I would rather talk with his mother than with his father. 我宁愿和他妈说话而不愿和他爸说话。三、在疑问句式中，would rather 与would ratherthan中的would要放在主语之前例 Would you rather stay here or go home? 你愿意呆在这里，还是回家？Which would you rather have, apples or bananas? 你喜欢吃苹果还是香蕉？Would you rather read a novel than read a poem?你宁愿看小

39、说而不愿朗读诗歌吗？四、would rather+从句，是一个常用的虚拟语气句型 Would rather+从句,谓语一般用过去时来表示现在或将来。其意为“宁愿,还是 好些”“一个人宁愿另一个人做某事”。引导从句的that常省略。在谈到过去的动作时，谓语则用过去完成时。例 John wants to see me today. I would rather he came to tomorrow than today. 约翰今天想去看我。我宁愿他明天来看我而不是今天。(句中came不是表示过去而是表示将来)Wed rather he paid us the money tomorrow. 我们

40、宁愿他明天付给我们那笔钱。Dont come tomorrow. Id rather you came next weekend. 明天别来。我希望你下周末来。请注意 1） 如果谈到过去的动作，也就是表示过去已经发生的事情在选择上不恰当。此时，主句一般为I had rather ,其（that）从句则用过去完成时。 例 Would rather you had not done that. 我真希望你没有做那件事。2）如果只涉及主语本人而不涉及另一个人，则would rather之后不接that从句而接have done结构。例 I would rather have gone to the

41、theatre than stayed home night. 我真希望昨天晚上去看了戏而不是呆在家里。 He would rather be poor than have got money by dishonest methods 他宁可穷也不愿意用不诚实的手段获取金钱。Henry would rather that his girlfriend worked in the same department as he does亨利希望他的女朋友和他在一个部门工作。五、would rather/sooner和prefer/would prefer的区别 would rather和would

42、sooner之间一般没有区别，但经常接触到的是would rather。例Tom would rather/sooner read than talk 汤姆宁可读书而不愿谈天。 Tom prefers reading to talking汤姆喜欢读书而不喜欢谈天。请注意 1）would rather后跟不带to的不定式+than+不带 to的不定式，而prefer后跟动名词+to+动名词。有时prefer后面也可跟名词，而在would rather之后要求只带动词原形。例 He prefers wine to beer= He would rather drink wine than beer

43、他喜欢喝红葡萄酒而不喜欢喝啤酒。I prefer tennis to golf= Id rather play tennis than golf我喜欢打网球而不喜欢打高尔夫球。 2）某些 prefer+名词的情况不能用 would rather完全确切地表达出来：He prefers dogs to cats（他喜欢狗而不喜欢猫。）和 He would rather have dogs than cats（他宁可养狗而不愿养猫。）很明显，这两句的意思并不完全相同。3） would rather+不带to的不定式有时可代替 would prefer+带 to的不定式。例 Id rather fl

44、y than go by sea=Id 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您想喝点杜松子酒吗？我想喝点咖啡。/我想喝点咖啡，不想喝杜松子酒。4）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 我们

45、是乘船去的，可我本想乘飞机去。（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。The pen is not compared to that one.这笔比不上那只。16 GrainGrain n.1. 谷粒CNot a grain of rice was wasted.一粒米也没有浪费。2. 谷物,谷类UCFarmers grow grain and keep cattle.农民种谷养牛。3.
