S,V,o,1. She often helps her mother.2. I want a cup of tea.3.I had lunch.,Have a try,基本句型 三 + +（主系表） 特点：句子谓语动词都不能表达一个完整的意思， 必须加上一个表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。 系动词可分四类： 1）be 连系主语和表语的作用,后可接动词外的任何词； 2）感官动词类 look, feel, smell, taste, sound等 +adj. 3）表示变化：get, grow, become, turn, go等 4）表示状态延续：stay, keep, remain, stand等,+adj.,+adj.,1.This is an English dictionary.Everything looks different.The weather becomes cooler. The door stays open.,Have a try,基本句型 四 + +IO +D（主谓间宾直宾） 特点：谓语动词必须跟有两个宾语才能表达完 整的意思。这两个宾语一个是动作的直 接承受者，另一个是动作的间接承受者。 通常可改为 S +V+DO+prep.+IO e.g. She gave me an apple. =She gave an apple to me.,1.She passed him a new dress.2. 2.John told me his idea.3.He shows me his new cap.4.My father buy a present for me .,Have a try,基本句型 五 + + +OC（主谓宾宾补）特点：动词虽然是VT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。 e.g. We made him the manager. S,V,O,OC,We keep the table clean.I saw them getting on the bus.He asked me to come back soon.,Have a try,典型例题分析,1.Plants need water. S+V+O ( 主 + 谓+ 宾 )2.The flower is so fresh.

S+V +O +OC (主 + 谓 + 宾 + 宾补)6.Many animals live in trees. S + V (主 + 谓),同一个动词使用的句型也不尽一样，因此在学习动词时， 应掌握动词的类型。以 get 为例： Hes getting angry. (S V P) Youll get a surprise. (S V O) He got his shoes and socks wet. (S V O C) 在句子中词类和词的位置也影响句子的句型和意思: I found the book easily. 我很容易地找到了这本书。( S V O ） I found the book easy. 我觉得这本书很容易。 （S V O C）,Attention:,按结构英语句子主要可以分成三种： 简单句， 并列句，复合句 e.g. 1) The teachers name is Smith. 2) The teachers name is Smith and the students name is John. 3) He is Smith who likes going hiking. - 4) He is Smith and he likes going hiking. 5) Hurry up, or youll be late. 6) I saw him when I walked past the street. 7) He often gets up early because he wants to catch the early bus.,简单句,并列句,复合句,并列句,并列句,复合句,复合句,Study skills,Look at the sun.,Its a sun day.,ny,The shine of the morning sun is bright.
