1、-一般现在时一、一般现在时的用法1表示经常的或习惯性的动作，常与表示频度的副词连用。常用的频度副词有： always、often、 usually、seldom、never、sometimes, every week (day, year, month), once a week, on Sundays。频度副词在句中通常放在行为动词之前，系动词、助动词之后。e.g. He often goes swimming in summer.他夏天经常游泳。I usually leave home for school at 7 every morning. 每天早上我七点离开家。2表示现在的状态。e

4、般现在时的句子转换:1）e.g. 陈述句：She is a student. 疑问句 Is she a student? Yes, she is./No, she isnt. 否定句 She is not a student. 陈述句：I can swim. 疑问句 Can you swim? Yes, I can. / No, I cant. 否定句 I can not swim.小结：当句子中有be动词或情态动词时，则把be动词或情态动词(can, could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句.2）e.g.陈述句：We get up at 7:00
5、every morning. 疑问句Do you get up at 7:00 every morning? 否定句We dont get up at 7:00 every morning. 陈述句：She has a little brother. 疑问句 Does she have a little brother? 否定句 She doesnt have a little brother. 小结：当句子中既没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does（单数she, he, it）变成问句；在主语后谓语动词前加助动词dont（I, you ,以及
6、复数), doesnt（单数she, he, it）变成否定句，助动词后的动词要变成动词原形。常见考点、典型例题与练习 练习: drink- go- stay-make- look- have- pass- carry- come-watch- plant- fly-study- brush- do-teach- swim- jump-walk- eat- copy-write plays- buy-小结：动词第三人称变化规则：一般情况下在单词后面加-s。 以s, x, ch, sh, o结尾的在单词后面加-es。以辅音字母加-y结尾的，把y变i再加-es, 以元音字母加-y结尾的，直接加-s
