2）倒装句，表示动作正在进行。
例如：Here comes the bus. = The bus is coming.
There goes the bell. = The bell is ringing. 3）在时间或条件句中。
例如：When Bill comes (不是will come), ask him to wait for me.
I'll write to you as soon as I arrive there.
4）在动词hope, take care that, make sure that等后。 例如：I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room. 5).表示按规定、计划或时间表将要发生的事。 例如：He starts next week. 他下个星期出发。 We leave very soon. 我们很快就离开。

这类用法限于表示“移动”的动词：go去，come来，leave离开，start出发，begin开始，arrive到达，take off起飞等。
三、动词变单三形式的规则：
1 一般情况下，动词后面直接加 -s.
例如：work---works bring---brings forget—forgets get---gets give---gives help---helps know---knows like—likes meet---meets look---looks live---lives love---loves order—orders say---says sit---sits see---sees show---shows sing---sings speak---speaks spell---spells take---takes think—thinks visit---visits wait---waits want---wants play---plays …
2 以s,x, ch, sh或 o 结尾的动词，在后面加 es。
例如：wash---washes watch---watches teach---teaches brush---brushes rush---rushes push---pushes go---goes do---does fetch---fetches guess---guesses fix---fixes 3 以辅音字母 + y结尾的动词，把 y变为 i 再加 -es.
例如： study-studies fly—flies try---tries carry---carries hurry---hurries marry---marries 4 特殊情况
例如：have---has 5 运用

四、现在进行时态 定义：

否定句：主语+is/am/are+not+现在分词

例：You are always changing your mind. 关于现在进行时的其他内容:
【No. 1】现在进行时的构成
现在进行时由\构成。be并不是助动词，而是am is are 这三个be动词。初学者最容易漏掉，它应与主语的人称和数保持一致。 【No. 2】现在进行时的应用
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。
(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。
【No. 3】现在进行时的变化
肯定句式：主语+be( am, is, are)+现在分词+其它.
否定句式：主语+be(am, is, are) +not +现在分词+其它. 一般疑问句：Be(am, is, are) +主语+现在分词+其它？
特殊疑问句：疑问词+be(am, is, are)+主语+现在分词+其它？
对现在进行时的特殊疑问句的回答，它不可以用Yes或No直接作答，要根据实际情况回答。
