1、句子成分知识点 【只有分析清楚句子成分，才能够理解句子结构。】一个句子是由作用不同的各个部分所组成的，这些组成部分被称为句子成分。句子成分可以是单词，也可以是短语或句子。在句中起主要作用的句子成分有主语和谓语，称为主要成分；起次要作用的有宾语、宾语补足语、定语、状语和表语等，称为次要成分。1.主语主语是一句的主体，是全句述说的对象，通常用名词或相当于名词的词（即：名词、形容词或分词（与定冠词the连用表示一类人或物）、数词、代词、动词不定式（短语）、动名词（短语）以及主语从句等）担任。一般置于句首。如：Boy studentslike to play football on the playg

4、民共和国是1949年10月1日建立的。（时间作主语）Tian An Men Squarefirst saw the raising of our five-star red flag on October 1st, 1949.1949年10月1日天安门广场上升起了我国第一面五星红旗。（地点作主语）2.谓语谓语或谓语动词是说明主语的动作或状态的，通常用动词担任，置于主语之后。如：The earthtravelsround the sun.地球绕着太阳转。（不及物动词作谓语）The playbeginsat eight. So wemust dineat seven.戏八点钟开演，所以我们必须七点
5、钟吃饭。（不及物动词作谓语）Iborrowedthe novel from the school library a week ago.一周前，我从学校图书馆借了这本小说。（及物动词作谓语）The new bookswill have been enteredin the register by the end of next week.这些新书在下周前将登记完毕。（及物动词的将来完成被动式作谓语）Heis one of the most popular professorsin the university.他是大学里最受欢迎的教授之一。（系动词+表语作谓语）3.宾语宾语表示行为动作的对象。
6、及物动词涉及到的对象叫动词宾语。一般置于及物动词之后。不及物动词后不能直接跟宾语，只有与介词连用构成短语后才可以跟宾语。介词后面的宾语叫介词宾语。通常用名词或相当于名词的词（即：名词、数词、代词、形容词或分词（与定冠词the连用表示一类人或物）、动词不定式（短语）、动名词（短语）、名词化的分词以及宾语从句等）担任。如：You can leaveyour luggagewith me.你可以将你的行李存在我这儿。（名词作宾语）If you add five to ten, you get fifteen.5加10得15。（数词作宾语）Where did you buythat?你在哪儿买的那个？

8、个女孩有多大年纪。（宾语从句作宾语）注：a.代词作动词的宾语时通常要用宾格（例外：who常可替换whom），代词作介词的宾语时只能用宾格。如：He showedmehis photographalbum.他把照相册拿给我看。（代词宾格作间接宾语，名词作直接宾语）You can leave your luggage withme.你可以将你的行李存在我这儿。（代词宾格作介词宾语）b.介词之后要求跟带疑问词的动词不定式（短语），而不能跟简单的动词不定式。如：The teacher gave us much advice onhow to learn English well.老师给我们提出了许多学
9、好英语的建议。The problem ofhow to get the grand piano through the doorwaybaffled the workman.如何使这个大钢琴通过门廊难住了工作人员。c.如果宾语是与动词同源的名词，可构成同源宾语结构。这种宾语前有不定冠词和其它限定词修饰。如：Weare living a happy life.我们过着幸福的生活。Chris willsing an English songfor us.克里斯将要给我们唱支英文歌。Last night shedreamed a sweet dream.昨天晚上她做了一个甜蜜的梦。Theyfough
