1、 Predicate (谓语)谓语表述主语的行为动作或所处的状态。谓语的中心词是限定动词，有人称、数的变化。谓语大体上可以分为两类：简单谓语和复合谓语。简单谓语凡是由一个动词或短语动词构成，不管是什么时态、语态、语气，都是简单谓语。The plane takes off at 8 but this morning it may be delayed by the thick fog飞机八点起飞，但今天早晨可能会被大雾耽搁。I have tried this way three times and failed three times我用这种方法试了三次，失败了三次。复合谓语复合谓语一般由两部分
2、构成：一是带不定式的复合谓语(由情态动词或某些动词加不定式结构)；一是带表语的复合谓语(由系动词或少数其他动词加表语构成)。I would like to invite all my friends to the get-together我想邀请我所有的朋友去参加聚会。Our school becomes more beautiful and more contacted with the outside world我们的学校变得更加漂亮，与外界的联系也更广泛了。英语中的主谓一致主要遵循三个原则：意义一致原则、语法一致原则和邻近原则。这三个原则常常发生矛盾，但当发生冲突时，意义一致原则为优先考
3、虑的原则。语法一致原则主语和谓语通常是从语法形式上取得一致，即主语是单数形式，谓语动词也采取单数形式；主语是复数形式，谓语动词也采取复数形式。Mr Black is a well-known scientist on AIDS布莱克先生是著名艾滋病科学家。These books are intended for children under nine years old这些书是专门为九岁以下的儿童设计的。意义一致原则所谓意义一致原则是指谓语动词的变化是以主语所表达的单、复数概念而定。Three months has passed since you left(three months 表示单数
4、概念。)你已离开三个月了。The old are very well taken care of in our city(the old 指所有的老年人，指一类人，指复数概念。)老年人在我们城市被照顾得很好。邻近一致原则邻近一致原则是指谓语动词的变化是以靠近谓语动词的主语部分而定。Neither his parents nor he himself is a bank clerk(根据靠近谓语的主语he 而定。) 他父母和他本人都不是银行职员。Not Jack but his parents are to blame for the home accident(根据靠近谓语的主语 his pa
5、rents 而定。)不是杰克而是他父母应为这个家庭事故受到责备。考点分析：At last，we found ourselves in a pleasant park with trees providing shade and _ down to eat our picnic lunchAsitting Bhaving sat Cto sit Dsat答案：D。本题考查并列谓语的选择。found 与 sat down 应为并列谓语，而其余各项均为非谓语动词形式不能单独作谓语，解题时务必注意并列连词的作用，Professor Smith，along with his assistants，_ on the project day and night to meet the deadlineAwork Bworking Cis working Dare working答案：C。本题考查主谓一致用法。当“主语+along with/ with/ together with + n. / pron ” 结构作主语时其谓语动词的单复数应与主语保持一致。 因 Professor Smith 作主语，故应用单数谓语动词 is working。
