初一英语am is are及练习题
课时一 am is are一、 重点语法1. 动词be（am,is,are）的用法：be动词包括“am”, “is”, “are”三种形式。第一人称单数(I)配合am来用。句型解析析：I am+例句：I am Snoopy.I am ten years old. I am a student. I am a boy.第二人称(You)配合are使用。句型解析：You are+例句：You are my good friend. You are a good teacher.You are beautiful第三人称单数(He or She or It)配合is使用。句型解析：She(He, It) is +例句：She is a good girl.She is so tall.She is short.人称复数 (we /you/they)配合are使用。句型解析：We (You, They) are +例句 We are in Class 5,Grade 7.They are my friends.You are good students.二、Be动词在一般过去时中的变化：1am 和is在一般过去时中变为was。（was not = wasnt）2are在一般过去时中变为were。（were not = werent）3带有was或were的句子，其否定、疑问的变化和am,is, are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首。am, is, are的注意事项 1. is和are可分别与not缩写为isnt和arent，但am却不能与not缩写为amnt ，虽然有人把它缩为aint，但这毕竟是规范的口语说法，不宜仿用。2. 陈述部分为第一称肯定式时的反意疑问句，通常用arent如：Im late, arent I?我迟到了，是吗？3. 不要认为在主语之后总是用am。试看：Both he and I are right. 他和我都对。或他和我都不对。Neither he nor I am (或are) right. 他和我都不对. "I" is an English letter. I是英语字母。4. 当am, is are 位于句末时，均不能与主语缩写。如：Tell me where he is (不能用hes )。告诉我他在哪儿。He is taller than I am (不能用Im )。他比我高。A：Are they watching TV? 他们在看电视吗？B：Yes, they are. (不能用theyre)是的。注：若其后有not时，am, is, are则可以与主语缩写，其中is和are 也可与not 缩写。如：Are they watching TV? -No, theyre not (或they arent).用法口诀：我(I)用am, 你(you)用are，is跟着他(he)，她(she)，它(it)。单数名词用is，复数名词全用are。变否定，更容易，be后not加上去。变疑问，往前提，句末问号莫丢弃。还有一条须注意，句首大写莫忘记。一. 用括号中适当的词填空。1. I _(am, are, is) from Australia.2. She _ (am, are, is) a student.3. Jane and Tom _(am, is, are) my friends.4. My parents _ (am, is, are) very busy every day.5. _ (Are, Is, Do, Does) there a Chinese school in New York?6. _ (Be, Are, Were, Was) they excited when he heard the news?7.
