以上我们已经通过归纳总结和练习对本课的语法内容有了一定的了解，下面就让我们根据之前练习的考察情况进一步选择讲解该语法项的重难点。

一般现在时与现在进行时的区别： 一般现在时强调动作的经常性和反复性，而现在进行时强调动作的暂时性。如：He studies in N. 2 Junir High Schl. He is studying English in the classrm. 表示感觉或状态的动词一般不用现在进行时，而用一般现在时表示现在的感觉或状态。如：This ring belngs t my mther.

一般过去时与过去进行时的区别： 过去进行时强调动作的进行过程，而一般过去时强调动作的完成。如：I was reading a French nvel last night.(不强调读完)I read a French nvel last night. (强调读完) 过去进行时强调动作在过去某时间正在进行，而一般过去时则表示动作在过去某事件发生。如：My father was watching TV at seven yesterday.My father watched TV last night.
过去进行时强调动作的连续性，不可与确定的频度状语连用。一般过去时强调动作的反复性，可与确定的频度状语连用。如：The little girl was crying all afternn yesterday.The little girl cried five times yesterday.
