Key grammar 现在进行时态 一、现在进行时的用法

1、表示说话时正在进行或发生的动作。如: I’m babysitting my younger brother. 我在照看我弟弟。 It’s raining outside. 外面正在下雨。

2、表示现阶段一直在进行或不断重复的动作,但说话时该动作并不一定在进行。如: He’s watching an interesting TV play these days. 近来,他在看一部很有趣的电视剧。

Are you teaching English in a school? 你在学校教英语吗?

3、表示最近的确定安排,即根据计划或安排在近期内将要发生的动作。这是表示眼前打算最普通的说法,但一般要与表示将来的时间连用,以避免现在进行时和一般将来时的含义上的混淆。例如:

I’m meeting you at the airport this evening. 今晚,我会到机场接你。 What are you having for dinner? 晚饭吃什么?

4、表示从一个地方到另一个地方位置移动的动词(如go, come, drive, fly, travel, arrive, leave, start, visit,run,return等),以及动词do等的现在进行时形式,可以用来表示没有确定安排的决定或计划。

He’s leaving for Beijing tomorrow. 他明天动身去北京。 What are you doing next Sunday? 下星期天你要干什么?

5、现在进行时和always,usually,all the time等连用时,表示一种经常、反复的动作,且说话人往往带有某种感情色彩(如赞扬、欣赏、厌烦、批评、惊讶、不理解等)。例如: She’s always helping others. 她总是乐于助人。(表示赞赏) You are always talking in class. 你上课老是说话。(表示批评) 二、现在进行时的谓语部分构成

现在进行时在句式的变化上,都应在助动词be上做文章。 1、 肯定式:be(am, is, are)+ Ving(现在分词) 如: They are having an English class. 他们在上英语课。 2、 否定式:be(am, is, are) + not + Ving(现在分词) 如: They aren’t having an English class. 他们不在上英语课。

3、 疑问式:将be的具体形式(即am, is或are)提前到句首。如: Are they having an English class? 他们在上英语课吗?

助动词变化口诀:变疑问,往前提,句后问号莫丢弃;变否定,更容易,be后not 莫忘记。

三、现在分词的变化规则

1、 一般在词尾加-ing(一般-ing)。例如: going,playing,knowing

2、 以不发音的字母e结尾,先去e再加-ing(去哑e)。例如:making,arriving,coming 3、以重读闭音节结尾,且词尾只有一个辅音字母时,先双写这个辅音字母,再加-ing(重闭单辅先双写)。例如:running,stopping,preferring

4、 以-ie结尾,先将-ie改成y,再加-ing。例如:tying,dying, lying

口诀:现在进行ing,以e 结尾要去e,除去几个特殊词,系住tie-tying死去die-dying要躺下lie-lying,直接ie变成y。 四、现在进行时态的常见提示语

1、在汉语中,通常有“在,正在”等提示词。如: 我在做作业。I am doing my homework.

2、在英语中,最常见的提示词有now,look,listen以及at the moment(此时此刻)等。如: Look,they are playing football. 瞧!他们在踢足球。 五、运用现在进行时常见的几个错误 1、把动词变成现在分词形式易出错。例: (1)误:They are swiming (swim) . 正:They are swimming (swim). (2)误:Jenny is plaiing (play) football. 正:Jenny is playing (play) football.
