1、一般现在时讲解及练习1. 一般现在时： 1.表示事物或人物的特征、状态。如：The sky is blue.天空是蓝色的。2.表示经常性或习惯性的动作。如：I get up at six every day.我每天六点起床。3.表示客观现实。如：The earth goes around the sun.地球绕着太阳转。2. 构成：1. be动词：主语+be(am,is,are)+其它。如： I am a boy.我是一个男孩。2.行为动词：主语+行为动词(+其它)。如： We study English.我们学习英语。当主语为第三人称单数(he, she,it)时，要在动词后加-s或-es。
2、如：Mary likes Chinese.玛丽喜欢汉语。注意：一般现在时经常和频率副词连用。3. 我的变化-否定句、一般疑问句、特殊疑问句：1. be动词的变化。否定句：主语+ be + not +其它。如：He is not a worker.他不是工人。一般疑问句：Be +主语+其它。如：-Are you a student? -Yes.

3、单数时，要用doesnt构成否定句。如： He doesnt often play.一般疑问句：Do( Does ) +主语+动词原形+其它。如： - Do you often play football? - Yes, I do. / No, I dont.当主语为第三人称单数时，要用does构成一般疑问句。如： - Does she go to work by bike? - Yes, she does. / No, she doesnt.特殊疑问句：疑问词+一般疑问句。如：How does your father go to work?动词第三人称单数形式构成规则动词原形变第三人称单数的
4、规则与发音规律同名词单数变复数大致相同，请认真观察。1、大多数动词在词尾加“S”在清辅音后发音为s，在浊辅音及元音后发音为 z。如： stopstops s makemakes s readreads z playplays z2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读iz 如： flyflies z carrycarries z studystudies z worryworries3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为iz 如： teachteaches iz watchwatches iz4、以“o”结尾的动词，加“es”，读z
5、如： gogoes z dodoes z下面几个动词变为单数时，原词的元音部分的发音发生了较大的变化，请注意记忆。 如：1）、do du:does dz2）、say seisays sez 以不发音字母“e”结尾的开音节词，如果尾音是s，z时，加“s”后字母“e” 发音， 与所加“s”一起读做iz。 如： closecloses izbe动词包括：am， is， are。第三人称单数用 is；过去式为 was；复数are，过去式为were.have，遇到主语是第三人称单数时，要用 has； 动词 be 的第三人称单一般现在时练习题(一) 写出下列动词的第三人称单数形式：drink-_go-_s
