现在进行时
一、现在进行时的构成：
现在进行时由"be+现在分词（v-ing）"构成。

Be动词应与主语的人称和数保持一致，即：I am/he/she/it 包括单数名词和不可数名词用is, you/we/they 包括复数名
词用are.
The students are listening to the teacher.
He is watching TV now.
现在分词变化规则如下：
1.动词后直接+ ing(例：sleep+ing sleeping)
2.去掉不发音的e+ing(例：bite-e+ing biting write-writing, make-making take-taking)
3.重读闭音节，且末尾只有1个辅音字母，双写辅音字母+ing(例:sitting, beginning,getting,putting，running，stopping，cutting ）
4.特殊变化：die-dying,lie-lying，tie-tying

二、现在进行时的应用
A表示现在( 指说话人说话时) 正在发生的事情(now，at the moment )
What are you doing?
I am watch TV now.
B. 表示当前一段时间内的活动或者现阶段正在进行的动作(these days，this week，this month,this term)
We are working on a farm these days.
I’m reading a history book this month.
C.已经确定或安排好的将来活动。

I'm leaving for a trek in Nepal（尼泊尔）next week.（已经安排了）
we're flying to Paris tomorrow.(票已经拿到了）
在实际运用时，现在进行时常用以下几种情况：
(1)当句子中有now时，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。

We are having an English class at the moment.我们正在上英语课。

(2)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。

如：Listen！She is singing an English song.听，她正在唱英语歌。

(3)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 model planes these days.这些天我们在做飞机模型。

(4)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。

如：Look at the picture. The children are flying kites in the park.看这幅图，那些孩子正在公园放风筝。
