现在进行时
一、现在分词的构成规则：
（1）一般在动词后加“ing”。 例：read — reading
（2）以不发音的“e”结尾的动词，去“e”加“ing”。例：write — writing。
（3）以重读闭音节结尾的并且末尾只有一个辅音字母，双写这个辅音字母再加“ing”。例：put — putting。
（4）以“ie”结尾的动词改为“ie”为“y”再加“ing”。例：lie — lying。
二、写出下列动词的现在分词：
swim ____________  eat ______________  like ______________  sing________________
tie ______________  step _____________   keep ______________ wait ________________
do _______________  go _____________   forget  ____________ prefer ______________
三、现在进行时的用法：
（一）概念：
表说话的瞬间正在发生的动作或存在的状态，常与：look, listen, now look,  listen,  now,  at present，at the moment …..连用。谓语构成：am / is / are + V.ing
例：Look! The children are playing football over there.
（二）现在进行时的肯定句、否定句和一般疑问句的构成，以动词dance为例。
句式
结构

肯定句
I
am
dancing.


You
are



He / She/ It
is


否定句
I
am
not
dancing.


You/We / They
are




She / He/ It
is



一般疑问句
问句
回答


Am
I
dancing?
Yes,
I
am.






you / we / they
are.


Are
you / we / they


he / she / it
is.





No,
I’m
not.


Is
he / she / it


you / we / they
aren’t.






he / she / it
isn’t.

（三）现在进行时使用中的一些易错问题：
1．把动词原形转换成现在分词形式时易出错
例：（1）They are swiming.(swim)      应该为：________________________
   （2）Jenny is plaiing(play)football.   应该为：________________________
解析：动词变现在分词可有如下口诀:“一添一去y不变”. “一添”指双写规则；“一去”指去掉不发音字母e规则；“y不变”指要与名词变复数区分开。
2．丢掉be动词或忘记把动词变成现在分词
例：（1）Look, two children flying (fly) a kite in the park.   应该为：________________________
?  （2）Li Ming isn’t read ( not read) a book in bed now.   应该为：________________________
解析：现在进行时肯定句的结构规律为: “be+现在分词,缺一不可”。这一点必须牢记。
3．对动词或动词词组提问时丢掉doing
例：The students are singing in the room.(对划线部分提问)
What are the students in the room?  （错误）
应该为：______________________________________
解析：现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?”句式。
4．现在进行时态的选择疑问句中易忽视or后用现在分词形式
例：孩子们在跑还是在跳？?   Are the children running or jump?
应该为：______________________________________
解析: or连接的是两个并列成分，动词形式须一致。
