15、現(xiàn)be ，如：I am a student我是一名學(xué)生。b否定句中，要在be 后面加not ，如：She isnt a teacher她不是教師。c一般疑問句，要將 be 放在句子開頭（注意句首字母大寫），句尾用問號(hào)，答語用Yes ，主語 +be 或 No ，主語 +be+not 如：Are you ready ？ 你準(zhǔn)備好了嗎？Yes ， I am 是的，我準(zhǔn)備好了。（ No ， Im not 不，我沒準(zhǔn)備好。）（2 ）實(shí)義動(dòng)詞 型：句中的 謂語動(dòng)詞 為實(shí)義動(dòng)詞 （也叫 行為動(dòng)詞 ）：a 肯定句 中，只出現(xiàn) 實(shí)義動(dòng)詞 ，如：I get up in the morning我早晨起床。b否定句中
