现在进行时讲解
现在进行时：
一、现在进行时的构成：主语+be动词（am /is /are）+v（动词）+ing形式 注意：这里的-ing 形式叫做现在分词
二、现在进行时句型变化：
1、肯定式：be(am, is, are)+ V-ing(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 + V-ing(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?
4、特殊疑问句式：
特殊疑问句结构：特殊疑问词＋一般疑问句？
现在进行时的特殊疑问句结构：特殊疑问词+be(am/ is/are)+主语+doing（+其他成分）？
eg:1、What are you doing ? 你们正在干什么？
We are playing.
2、What is the old man doing under the tree?
那棵树下的老人在干什么？
The old man / He is reading a book.
3、Where is the boy swimming? 那个男孩正在那里游泳？ The boy / He is swimming in the river.
注1：is not可以缩写成isn„t，are not可以缩写成aren‟t，但是am not在现代英语中不可以缩写。
注2：1、be 动词在现在进行时里算作“助动词”，翻译现在进行时的时候，be 不能解释为“是”， 否则不通顺。它只是和现在分词搭配构成“进行时”。
2、变一般疑问句时，形成“一问一答”的关系，要注意第一人称和第二人称相互交换。
3、简略回答时，所有称呼要简化为人称代词：I ，we ，you ，he ，she ，it ，they 。
三、现在进行时的应用
（1）现在进行时主要表示说话人的说话时刻正在进行的动作。
Be quiet! The baby is sleeping. 安静，孩子在睡觉。
He is teaching in a middle school. 他在一所中学教书。 (目前阶段在进行的动作)
（2）当句子中有now 时，经常表示动作正在进行，这时要用现在进行时。如： They are playing basketball now. 现在他们正在打篮球。
（3）以look ，listen 开头的句子，提示我们动作正进行，这时要用现在进行时。 Listen ！She is singing an English song. 听，她正在唱英语歌。
（4）表示当前一段时间或现阶段正在进行的动作，且此时有this week，these days等时间状语，这时常用现在进行时。如：
We are making building these days. 这些天我们在做飞机模型。
（5）描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。 Look at the picture. The children are flying kites.
看这幅图，那些孩子正在放风筝。
（6）现在进行时表将来, 主要表示按计划或安排要发生的动作：
某些词，如come ， go ， leave ， arrive ， start ， get ， stay ，live, fly等的一般现在时也可表示将来.
例如：I‟m leaving tomorrow. 我明天走。
They‟re getting married next month. 他们下个月结婚。
I‟m not going out this evening. 今晚我不准备出去。
What time does the train leave? 火车什么时候开?
四、动词变现在分词的规则
五、现在进行时与一般现在时的区别
(1) 现在进行时强调目前正在进行的动作，而一般现在时强调经常性或习惯性的动作。如：
I‟m reading a story now. 我在看一个故事。(目前正在干的事情)
I read stories in my spare time. 我有空时看故事。(经常性的行为)
(2) 现在进行时强调现阶段一直在进行的动作，而一般现在时只表动作的重复，而不表示动作的持续。如：
What are you doing these days? 这几天你在干什么?
They are learning English in the summer holiday. 他们暑假在学英语。 They read English every day. 他们每天读英语。
They play volleyball every Sunday. 他们每周星期天都打排球。
(3) 表示短促动作的动词(如 jump, knock, beat, pick, skip等) 的进行时，表示动作的重复。如：
The girls are jumping over there. 女孩子们在那边跳。
His heart is beating fast. 他的心脏跳得很快。
