“一般现在时”与“现在进行时”的区别
到目前为止,我们已经学过了一般现在时和现在进行时这两种时态。那么,它们之间有什么区别呢?仔细观察下面的例句,然后补全结论部分所缺的内容。
【例句】
1. 一般现在时:
I am happy. / She is a student. / They are free.
Lily often / always / usually / sometimes / never walks to school. The boys play basketball every day / on Sundays / once a week.
2. 现在进行时:
I am reading newspapers now.
Mr. Wang is writing a book these days / all the morning.
Look! The children are dancing in the room.
【结论】
通过观察上面的例句,我们可以发现:
1. 表示经常性、习惯性的动作或表示主语现在的身份、特征或状态等用____________(一般现在时/ 现在进行时);而表示说话时正在发生或进行的动作用____________(一般现在时/ 现在进行时)。
2. 一般现在时和现在进行时的谓语结构不同。一般现在时的谓语结构通常为:be动词(am / is / are),行为动词原形或第三人称单数形式;而现在进行时的谓语结构为:be动

3. ____________(一般现在时/ 现在进行时)常与always, usually, often, sometimes, never, every day, on Sundays以及表示频率的词语等连用;____________(一般现在
时/ 现在进行时)常与now, right now, these days, all the morning等时间状语连用,同时,Look! 和Listen! 也是这一时态的明显标志。
