一:现在进行时:用在叙述某人正在做某事的时候。(某动作正在进行)
其结构是“be动词 + 动词ing”,句中可能会有look,listen,now或一个相当具体的时间。动词加“ing”(现在分词)的变化规则:
1、接在动词后面加“ing”
2、“元音+辅音+e”结尾的单词把e去掉再加ing。
3、重读闭音节双写最后字母再加ing,单词有:run—running、swim—swimming、put—putting、get—getting、shop—shopping 1.)What is Mary doing?She’s shopping.2.)Is Betty swimming now?No, she isn’t.She’s running.3.)It’s seven thirty in the evening.We’re having dinner at home.二:一般现在时:用来叙述经常性发生的事情、习惯和爱好等,时间词有sometimesoftenusuallyevery morning(afternoon,evening,day,week,year)on Monday等(注意此时要先弄清叙述的人或事物是否第三人称单数。即he、she、it。)

动词第三人称单数变化规则:
1)直接在动词后面加“s”。2)以“s、x、sh、ch”结尾的单词,在动词后面加“es”。
wash---washeswatch---watchesfish---fishes 3)以“辅音+y”结尾的单词,把y改i再加es。carry---carrietudy---studiesfly---flies
