基本知识:
一:一般现在时:表示经常性的事情。时间状语:often经常, usually通常, always总是, every每个, sometimes有时, at…在几点钟只有第三人称单数用动词三单,其余动词均用原形三单变化:多数在动词后加s ,如:play—plays like—likes;以s,x,sh,ch,o结尾的动词加es,如:go—goes wash--washes ;以辅音字母加y结尾,把y 改i再加es ,如fly—flies,study-studies
二:基本结构:动词原形(如主语为第三人称单数,动词上要改为第三人称单数形式)三:否定形式:am/is/are+not;此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
四:一般疑问句:把be动词放于句首;用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
五:但是,动词to be 和to have 的一般现在时的形式特殊如下:
