一般现在时和现在进行时区别及习题.doc

一般现在时和现在进行时是初一阶段所学的两种重要时态，它们的不同之处有以下几点：1)基本用不同；2)谓语动词的形式不同；3)时间状语不同；4)有不同的特殊用法。
一、基本用法不同
【1】一般现在时用来表示习惯性的动作或状态。如：She goes to school by bike every day.她每天骑自行车去上学。
【2】现在进行时用来表示现在(说话的瞬间)正在发生或进行的动作或者用来表示现阶段正在进行或存在的状态。如：Look ! She is reading under the tree.瞧！她正在树下看书。
二、谓语动词的形式不同
【1】一般现在时的谓语动词：1) be动词用am/is/are这三种形式；2)实义动词用动词原形或第三人称单数形式(根据主语数的变化而变化)。
【2】现在进行时谓语动词的形式为： am / is / are+动词-ing 形式。如： We go to school at seven in the morning.我们早晨七点钟上学。 I am reading English now. 我现在正在读英语。
三、时间状语不同
【1】一般现在时常与often, sometimes, always, usually等频率副词及once a week/day等频率短语连用，还与 every morning /day / week..., on Wednesday, in the morning / afternoon / evening等时间状语连用。
【2】现在进行时常与now, these days, these weeks等时间状语连用。句首有 Look ! / Listen !等提示语时，后面的句子中动词一般用现在进行时。
四、特殊用法
1. 一般现在时的特殊用法： 表示客观真理、自然现象往往要用一般现在时表示。如：The moon goes round the earth.月亮绕着地球转。
2. 现在进行时的特殊用法： 现在进行时与always 连用时，往往含有赞扬、厌恶、责备等感情色彩。如： He is always working hard.他总是非常努力地工作。(表示赞扬)
　come, go, begin, start, leave 等动词常用现在进行时表示将要发生的动作。如：I'm coming. 我就来。
