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，knowing2、以不发音的字母e结尾，先去e再加-ing（去哑e）。
例如：making，arriving，coming3、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，preferring4、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。
