Unit 8 Fashion 语法学案：现在进行时

现在进行时
一、考点归纳
　初中阶段对现在进行时的考查主要集中在以下几个方面：
　　1、现在进行时的结构；
　　2、通过时态关键词正确地判断时态；
　　3、现在分词的正确变化。
　　考查的主要形式是单项选择、根据所给词的适当形式、补全句子等。阅读理解和书面表达中也会出现相关的用法。
在初一上册的书中也会对这一时态进行深入的学习，结合单元的重要句型来给学生复习巩固这一知识点。
二、基本结构
构成:
主语+be
(am,
is
,are
)+动词现在分词-ing形式
注意：be动词与现在分词，二者缺一不可。
现在分词的构成：　
①一般在动词尾加ing
例：play
→playing
②以不发音字母e结尾的动词，去e加ing
例：make
→making
③以重读闭音节结尾，末尾只有一个辅音字母，先双写这一辅音字母，再加ing
例：put
→putting
④特殊的有
be→
being
lie→lying
tie
→tying
die→
dying

1）现在正在发生或进行的动作。例如：
I
am
looking
for
my
son
at
the
moment.

2）当前一段时期内的活动或现阶段正在进行的动作。例如：
They
are
living

Beijing
these
days.
