一、概念上的不同点:

一般现在时概念:表示通常性、规律性、习惯性、真理性的状态或者动作(有时间规律发生的事件)的一种时间状态。
现在进行时概念:现在进行时表示动作发生的时间是“现在”,动作目前的状态是“正在进行中”。所谓“正在进行中”,是指在谈到这件事的时候,这个动作还在进行中。至于它是什么时候开始的,什么时候会停下来,不是我们关心的。

二、结构的不同点:

一般现在时结构:常以动词原形表示,但当主语是第三人称单数时,应用动词的单数第三人称形式。
现在进行时结构:主语+be+v+ing〔现在分词形式)
不同点:一般现在时是表示现在经常性、习惯性的动作,或现在的状态,强调长期性、稳定性,而现在进行时是指现在此刻或现在这一时期内正在进行的动作,强调暂时性不稳定性。例如:

He usually gets up at six in the morning.(经常性、习惯性动作)
She is an Englishwoman.(现在的状态)
We are working on the farm these days.(现在这期间的动作,表示这几天暂时在农场上帮忙) Look! The boys are fighting.(现在此刻所发生的动作)
时间状语的不同

三、时间状语的不同

一般现在时常与often, sometimes, always, usually等频度副词和every morning / day / week, on Wednesday, on Sundays, in the morning / afternoon / evening等时间状语连用。现在进行时常与now, these days, at this moment等时间状语连用。句首有 Look! / Listen!等提示语时,后面的句子也要用现在进行时。如:

We often go shopping on Sunday.

Listen! Someone is singing an English song in the classroom.

体味以下句子的区别:
1.He works hard. 强调始终如一
2.He is working hard. 强调现在一直努力工作
3.Here comes the bus! (表高兴和欣慰)
4.I forget him name. I'm forgetting his name.(差点把他的名字忘了)
5.You don't eat much. (强调胃口不大)
6.The match starts at 7 o'clock. (比较固定,不宜改变)
7.The match is starting at 7 o'clock. (比赛将于7点开始)
8.Tom is always coming late.(表示不满,责备)
9.Tom goes to college now.
10.I'm expecting you to phone me.(婉转口气)
11.Apples cost more these days.(强调事实)
