小学英语一般现在时知识点?
⒈定义:一般现在时:表示经常性的事情,经常性的动作或一般性事实。
⒉用法:通常与频率副词never、sometimes、often、always、usually或时间短语in the morning、on sunday、every week等连用。
⒊一般现在时的句子转换:
①当句子中有be动词或情态动词时,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。
例:陈述句:She is a student.
疑问句→ Is she a student?
否定句→ She is not a student.
②当句子中即没有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don’t(I、you以及复数),doesn’t(单数she、he、it)变成否定句,助动词后的动词要变成动词原形。
例:陈述句:We get up at 7:00 every morning.

否定句:We don’t get up at 7:00 every morning.
