1第 1 课句子的三种模式(Be 句型) 导言本课的重点是掌握英语的三种基本句型，注意词性和词序，以及定语的位置,同时注意中英文表达上的相同和不相同的地方。三种基本句型虽然简单，但至关重要。掌握好它们，在今后的学习中有一通百通之效。其实英语只有三种基本句型主+系动词+表词序 1 主语 2 系动词 3 表语即句子的主体用于连接主语和表语 表示主语身份、状态以及所处的位置词性 * 名词代词Be(is, am, are)* 名词 形容词介词+*名词 (介词短语)注：*注意该结构中的名词，它们能被定语修饰。1 这个人 是 一个老师。 The man is a teacher. 主语 系 表语 主语 系 表语（名词）2 他 （是） 很忙。 He is busy. 主语 系 表语 主语 系 表语（形容词） 注意中文中的系动词经常被省略,而英文中绝不能省。3 她（是）在教室里。 She is in the classroom.主语 系 表语 主语 系 表语（介词短语）注：定语只修饰名词，不破坏句子的基本结构。通常由形容词和介词短语充当，形容词放在所修饰的名词之前，而介词短语放在所修饰的名词之后，请注意英语与汉语词序的不同。看懂中文的定语是翻译好定语的关键。be 的人称变化You (They We ) are teachers.He ( She ) is a teacher.I am a teacher-Be 的肯定否定及疑问的变化You (They We ) are teachers.He ( She ) is a teacher.I am a teacherYou (They We ) are not teachers.He ( She ) is not a teacher.I am not a teacher2Are you (They We ) teachers?Is he ( She ) a teacher?Am I a teacher?(定语的位置)那个人是个老师.The man is a teacher.那个人在教室里.The man is in the classroom. A big deskA small deskA beautiful girl 教室里的 那个人是个老师.The man in the classroom is a teacher.这个人在教室里.The man is in the classroom. 那个人在 二楼的 教室里.The man is in the classroom on the second floor.The man in the classroom 教室 on the second 第二 floor 层 is a teacher from England.The man in the classroom on the second floor is not a teacher from England.Is the man in the classroom on the second floor a teacher from England ?介词短语即可以做表语也可以做定语，虽然它们词性相同，但由于词序不同，它们所起到的作用也不同，当在 is 的后面是表语 ,跟在名词的后面它就起到定语的作用。本课要求：牢记第一个句型的旗帜- be(1) 人称变化(2) 肯定否定及疑问的变化(3) You (They We ) He ( She ) I be 的人称变化You (They We ) are teachers.He ( She ) is a teacher.I am a teacherBe 的肯定否定及疑问的变化You (They We ) are teachers.He ( She ) is a teacher.I am a teacherYou (They We ) are not teachers.He ( She ) is not a teacher.I am not a teacher3Are you (They We ) teachers?Is he ( She ) a teacher?1、 Am I a teacher?2、 介词介词短语的作用本课需记忆的介词(认识就行 ) in in front of on from3、 near of4、 介词短语的作用(1) 表语,位置在 be 之后：The man is in the classroom on the second floor.(2) 定语，名词之后：5、 The man is in the classroom on the second floor.6、 本课目的-牢牢抓住 - 主系表考试时减少查字典的次数，抓主句子的中心The man in the classroom on the second floor is not a teacher from England.课堂练习be 的人称变化( 变为否定与疑问)You (They We ) are a teacher.( teachers)He ( She ) is a teacher.I am a teacher英译汉1: The girl 女孩 in the classroom is a teacher from England.2:The fat lady 女人 in front of 在.前面 the hospital 医院 is a doctor 医生 from England .3:The TV set 电视 on the desk 桌子 in the living-room 客厅 is new 新的.4: The bird 鸟 near the red apple in the tree is blue. 5:The wallet 钱包 on the sofa 沙发 in the living-room is your fathers 你爸爸的.第 2 课Be 句型的时态变化课堂练习be 的人称变化You (They We ) are a teacher.( teachers)He ( She ) is a teacher.I am a teacher1: The girl in the classroom is a teacher from England.2:The fat lady in front of the hospital is a doctor from England .3:The TV set on the desk in the living-room is new.4: The bird near the apple in the tree is blue. 5:The wallet on the sofa in the living-room is your fathers.课堂练习答案1:教室里的那个女孩是从英国来的 老师.42:医院 hospital 前面的那个胖女人 fat lady 是从英国来的医生 doctor.3:客厅里桌子上的那台电视 TV set 是新的.4:树上的红苹果 apple 旁边的那只鸟是蓝色的 blue.5:客厅 living-room 里沙发 sofa 上的钱包 wallet 是你爸爸的.He, fool现在时肯定: You are rich. 否定: You are not rich.疑问: Are you rich?过去时was were肯定: You were rich . 否定: You were not rich.疑问: Were you rich?将来时肯定: You will be rich. 否定: You will not be rich.疑问: Will you be rich?
