I用am；you,we,they都用are,is連著he，she，it；

單數(shù)名詞用is,復(fù)數(shù)名詞全用are

變疑問，往前提，句末問號莫丟棄

變否認，更容易，be后not莫忘記

be動詞的使用方法:be動詞涉及“was”,“were”兩種形式。(普通過去時)一是時間狀語巧，表達過去的短語要記牢；二是形式巧，單數(shù)was，復(fù)數(shù)were；否認句構(gòu)造是三巧，not緊跟was／were；四是疑問句式巧，was／were向前跑(提前)?！疽磺伞繒r間狀語巧。普通過去時表達過去發(fā)生的動作或存在的狀態(tài)，恰巧與表達過去的某些時間狀語連用。]例如：yesterday,lastnight／week／month／year,lastSaturday,thedaybeforeyesterday,in1998,fiveyearsago等。【二巧】形式巧。它與普通現(xiàn)在時同樣，形式多樣：當(dāng)主語是第一人稱單數(shù)或第三人稱單數(shù)時，謂語動詞用was；主語是第二人稱或其別人稱復(fù)數(shù)時，謂語動詞用were。例如：Iwasintheclassroomyesterdaymorning．昨天早上我在教室里。HewasatschoollastTuesday．上周二他在學(xué)校。Theywereoverthereamomentago．剛剛他們在那邊?！救伞糠裾J句構(gòu)造巧。與動詞be的普通現(xiàn)在時同樣，它在動詞背面加not即可變成否認句，并且was,were與not能夠縮寫成wasn't,weren't。即：主語＋wasn't／weren't＋表語＋其它。例如：Iwasnot(＝wasn't)hereyesterday．昨天我不在這兒。Myparentswerenot(＝weren't)athomelastSunday．上周日我父母不在家。【四巧】疑問句式巧。把was,were提到句首，句末用問號即可變?yōu)槠胀ㄒ蓡柧?。即：Was(Were)＋主語＋表語＋其它？這恰巧與動詞be的普通現(xiàn)在時的疑問句式相似。例如：Wereyouathomethedaybeforeyesterday﹖前天你在家嗎？Wasshelatethismorning﹖今天早上她遲到了嗎？更巧的是疑問句的答語也相似，必定回答用“Yes,主語＋was／were．”；否認回答用“No,主語＋wasn't／weren't．”。例如：—WereWeiHuaandHanMeiherejustnow﹖剛剛魏華和韓梅在這兒嗎？—Yes,theywere．(No,theyweren't．)是的，她們在。（不，她們不在。）練習(xí)從下列各題后所給的四個選項中選擇最佳答案填空。()1．Myfather＿＿＿＿＿＿illyesterday．A．isn't B．a(chǎn)ren't C．wasn't D．weren't()2．＿＿＿＿＿＿yourparentsathomelastweek﹖A．Is B．Was C．Are D．Were()3．Thetwins＿inDalianlastyear．They＿herenow．A．a(chǎn)re;were B．were;are C．was;are D．were;was()4．＿yourfatheratworktheday＿yesterday﹖A．Was;before B．Is;before C．Was;after D.Is;after()5．—WhowasondutylastFriday﹖—＿．A．Iam B．Iwas C．Yes,IwasD．No,Iwasn't用was,were填空JohnandPaul_______verybusylastweek.I_______atschooljustnow.He________atth
