句子成分(Members of a Sentence)在句子中，词与词之间有一定的组合关系，按照不同的关系，能够把句子分为不同的组成成分英语的基本成分有七种：主语（subject）、谓语（predicate）、表语（predicative）、宾语（object）、定语（attribute）、状语(adverbial) 和补语（complement）英语句子的基本结构能够归纳成五种基本句型及其扩大、组合、省略或倒装掌握这五种基本句型，是掌握各种英语句子结构的基础英语五种基本句型列式如下：四： Ｓ Ｖ ｏ Ｏ （主＋谓＋间宾＋直宾）五： Ｓ Ｖ Ｏ Ｃ （主＋谓＋宾＋宾补）基本句型 一：Ｓ Ｖ （主＋谓）主语：能够作主语的成分有名词（如boy），主格代词（如you），动词不定式，动名词等主语一般在句首 谓语：谓语由动词构成，是英语时态、语态变化的主角，一般在主语之后 此句型的句子有一个共同特点，即句子的谓语动词都能表达完整的意思这类动词叫做不及物动词，后面能够跟副词、介词短语、状语从句等 Ｓ │ Ｖ （不及物动词） 1. The sun │was shining. 太阳在照耀着。
2. The moon │rose. 月亮升起了3. The universe │remains. 宇宙长存4. We all │breathe, eat, and drink. 我们大家都呼吸、吃和喝5. They │talked for half an hour. 他们谈了半个小时 6. The pen │writes smoothly 这支笔书写流利基本句型 二： Ｓ Ｖ Ｐ （主＋系＋表）此句型的句子有一个共同的特点：句子谓语动词都不能表达一个完整的意思，必须加上一个说明主语身份或状态的表语构成复合谓语，才能表达完整的意思这类动词叫做连系动词系动词分两类：be, look, keep, seem等属一类，表示情况；get, grow, become, turn等属另一类，表示变化be 本身没有什么意义,只起连系主语和表语的作用其它系动词仍保持其局部词义 Ｓ │Ｖ（是系动词）│ Ｐ 1. His face │turned │red. 他的脸红了2. The dinner │smells │good. 午餐的气味很好。
3. The trouble│is │that they are short of money. 麻烦的是他们缺少钱4. Everything │looks │different. 一切看来都不同了5. Our well │has gone │dry. 我们井干枯了 基本句型 三： Ｓ Ｖ Ｏ （主＋谓＋宾）此句型句子的共同特点是：谓语动词都具有实义，都是主语产生的动作，但不能表达完整的意思，必须跟有一个宾语，即动作的承受者，才能使意思完整这类动词叫做及物动词 Ｓ │Ｖ（及物动词）│ Ｏ 1. Who │knows │the answer? 谁知道答案？ 2. He │said │"Good morning." 他说："早上好！"3. I │want │to have a cup of tea. 我想喝杯茶4. He │enjoys │reading. 他喜欢看书5. He │admits │that he was mistaken. 他承认犯了错误基本句型 四： Ｓ Ｖ ｏ Ｏ （主＋谓＋间宾＋直宾）有些及物动词能够有两个宾语，如：give给，pass递，bring带，show显示。
这两个宾语通常一个指人，为间接宾语；一个指物，为直接宾语间接宾语一般位于直接宾语之前 一般的顺序为：动词 + 间接宾语 + 直接宾语如：Give me a cup of tea, please. Ｓ │Ｖ（及物）│ ｏ（多指人） │ Ｏ（多指物） 1. I │told │him │that the bus was late. 我告诉他汽车晚点了2.

I │gave │my car │a wash. 我洗了我的汽车基本句型 五： Ｓ Ｖ Ｏ Ｃ （主＋谓＋宾＋宾补）此句型的句子的共同特点是：动词虽然是及物动词，但是只跟一个宾语还不能表达完整的意思，必须加上一个补充成分来补足宾语，才能使意思完整宾语补足语：位于宾语之后对宾语作出说明的成分。
宾语与其补足语有逻辑上的主谓关系Ｓ │Ｖ（及物）│ Ｏ（宾语） │ Ｃ（宾补） 1. I │saw │them │getting on the bus. 我看见他们上了那辆公共汽车2. They │painted │the door │green. 他们把门漆成绿色3. This │set │them │thinking. 这使得他们要细想一想4.
