Section Grammar,探究语法精要,在正式的英语书面语及非正式的英语口语中，常用不同方式来告知人们我们认为他们该做什么，归纳起来，有以下几种表达说服的方式：,说服,一、英语书面语 在正式书面表达中，下列表达方式可以强化“建议”。 1should/ought todo. You should/ought to brush your teeth before you go to bed. 你在睡前应该刷牙。 We ought to go and see Mary tomorrow，but I dont think we will.我们应该明天去看玛丽，可我认为我们去不了。,2当人们想要表达建议、命令或要求时，从句的谓语动词需用虚拟语气，其形式为“(should)动词原形”。这些从句可以是宾语从句、主语从句、同位语从句或表语从句。 Our teacher demanded that Mary (should) finish her homework within a week. 我们老师要求玛丽在一周内完成作业。 His suggestion is that we (should) do our homework more carefully.他的建议就是我们的工作要更细心一些。,名师点津：“一、二、三、四”记虚拟：一个“坚持”(insist)；两个“命令”(order，command)；三条“建议”(advise，suggest，propose)；四项“要求”(demand，require，request，ask)。 (1)suggest作“建议”讲，宾语从句用虚拟语气；若作“暗示，表明”讲，则用陈述语气。 (2)insist作“坚持认为、坚持说”讲时，宾语从句不用虚拟语气。只有当insist作“坚持(要求)”“坚持(应该)”讲时宾语从句才用虚拟语气。,The Arab insisted that he had never seen the camel and that he (should) not be punished for its lost. 那个阿拉伯人坚持说他从未见过那头骆驼，并且坚持认为自己不能因为骆驼的丢失而受到惩罚。 Janes pale face suggested that she was ill，and her father suggested that she (should) have a medical examination. 简苍白的脸色表明她生病了，她父亲建议她做一下医学检查。,3Its(high/about)time that句式中，that从句中的谓语动词常用过去式或should do，should不能省略。 Its high time that I went/should go to pick up my daughter at school. 我该去学校接我的女儿了。,二、英语口语 1跟熟人交谈时用下列表达方式可以使“建议”听上去不生硬，具有试探性。 (1)虚拟语气表示委婉、客气的语气，常用句型“If I were you，Iddo.” If I were you，I would accept his advice. 如果我是你，我会接受他的忠告。 (2)句型I think you should/ought to do.，表示“我认为你应该做，”语气稍强。 I think you ought to tell your husband youre pregnant. 我想你应该告诉你丈夫你怀孕了。,2用下列方式可以强硬地对某人批评、责怪或提出建议，使用这种方式常具有权威性。 (1)Id rather (that)一般过去时/过去完成时 Id rather she set out to do the work now. 我宁愿她现在就着手做这项工作。 (2)Youd better do.
