最新小学be动词的用法总结及练习题

精品文档精品文档精品文档精品文档精品文档精品文档Be动词的用法一、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：Iam+…第二人称(You)配合are使用。句型解析：Youare+…第三人称单数(HeorSheorIt)配合is使用。句型解析：She(He,It)is+…人称复数(we/you/they)配合are使用。句型解析：We(You,They)are+…be动词前面的人称，是不可随意替换的。例如：Iam,Youare,Sheis，并不会出现Iis,Youam,Sheare这样的情形。请记住以下口诀：我用am，你用are，is连着他，她，它；单数名词用is，复数名词全用are。变疑问，往前提，句末问号莫丢弃。变否定，更容易，be后not莫忘记。疑问否定任你变，句首大写莫迟疑。二、Be动词在一般过去时中的变化：am

和is在一般过去时中变为was。（was

not

=

wasn’t）are在一般过去时中变为were。（were

not

=

weren’t）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be的过去时有四巧：一是时间状语巧，表示过去的短语要记牢；二是形式巧，单数was，复数were；三巧是否定句结构，not紧跟was／were；四是疑问句式巧，was／were向前跑(提前)。【一巧】时间状语（即标志词）巧。一般过去时表示过去发生的动作或存在的状态，恰巧与表示过去的一些时间状语连用。【二巧】形式巧。它与一般现在时一样，形式多样：当主语是第一人称单数或第三人称单数时，谓语动词用was；主语是第二人称或其他人称复数时，谓语动词用were。例如：Iwasintheclassroomyesterdaymorning．昨天早上我在教室里。HewasatschoollastTuesday．上周二他在学校。Theywereoverthereamomentago．刚才他们在那边。【三巧】否定句结构巧。与动词be的一般现在时一样，它在动词后面加not即可变成否定句，并且was,were与not可以缩写成wasn't,weren't。即：主语＋wasn't／weren't＋表语＋其他。例如：Iwasnot(＝wasn't)hereyesterday．昨天我不在这儿。Myparentswerenot(＝weren't)athomelastSunday．上周日我父母不在家。【四巧】疑问句式巧。把was,were提到句首，句末用问号即可变为一般疑问句。即：Was(Were)＋主语＋表语＋其他？这恰巧与动词be的一般现在时的疑问句式相似。例如：Wereyouathomethedaybeforeyesterday﹖前天你在家吗？Wasshelatethismorning﹖今天早上她迟到了吗？更巧的是疑问句的答语也相似，肯定回答用“Yes,主语＋was／were．”；否定回答用“No,主语＋wasn't／weren't．”。例如：—WereWeiHuaandHanMeiherejustnow﹖刚才魏华和韩梅在这儿吗？—Yes,theywere．(No,theyweren't．)是的，她们在。（不，她们不在。）
