句型
一般现在时:There
is

There
are+复数……
一般过去时:There
was

There
were+复数……
一般现在时和一般过去时的区别一、概念
1、一般现在时用于表示经常性或习惯性的动作或存在的状态;表示客观事实或普遍真理;
在时间、条件等状语从句中表示将来。
2、一般过去时表示在过去某个特定时间发生,也可以表示过去习惯性、经常性的动作。一般不强调动作的影响,只说明事情。一般过去时常与表示过去的时间状语或从句连用。
二.句法结构
1、一般现在时当主语是第三人称单数时,动词变相应的第三人称单数形式,肯定句:主语
+动词第三人称单数形式+其它;否定句:主语+doesn't+动词原形+其它。当主语不是第三人
称单数时,肯定句:主语+动词原形+其它,否定句:主语+don't+动词原形+其它。
2、一般过去时没有第三人称单数形式,肯定句形式为主语+动词过去式+其他,否定句形式为主语+didn't
+谓语动词原形+其他。
