二、现在进行时
一、概念
现在进行时表示说话时正在进行或发生的动作,也可表示当前一段时间内的活动或现阶段正在进行的动作。结构：助动词 be ( am / is / are ) +现在分词.
二、 现在分词的构成：
1.大多数动词后可在动词后直接加-ing．
Eg: carry-carrying,catch-catching,drink-drinking, enjoy-enjoying hurry-hurrying ,do-doing , read-reading , think-thinking
2. 如果动词以-e结尾,则去掉-e,再加-ing,
如come-coming , have-having , make-making,ride-riding,write-writing,take-taking,use-using．
3. 如果动词只有一个元音字母,而其后跟有一个辅音字母时,将此辅音字母双写,再加-ing 如： hit-hitting,let-letting, put-putting,run-running,sit-sitting．
4. 如果动词有两个音节,且重音在第二个音节上,则末尾的辅音字母须双写,再加-ing, 如: forget-forgetting,prefer-preferring,upset-upsetting．试比较 benefit/benfiting, differ/differing,profit/profiting,这些词的重音在第一个音节上,因此其末尾的辅音字母不双写．
5. 以 -ic 结尾的动词,应先把 -ic 变为 -ick,再加 -ing,eg: panic/panicking,picnic/picnicking,
但 lie/lying ,die/dying,tie/tying是特殊变化要记住．
三、句型结构：
1.现在进行时的肯定形式、否定形式、疑问形式及其回答,所有变化都体现在助动词 be ( is / am / are ) 上．
1)现在进行时的肯定形式：主语+be(am/ is/are)+doing+其他成分
I am singing . They are writing .
2)现在进行时的否定形式:主语+be(am/ is/are)+not +doing+其他成分
I am not singing . They aren’t writing .
3）一般疑问句及回答：be(am/ is/are)+ 主语+doing+其他成分
Am I singing ? Yes ,you are . / No ,you aren’t .
Are they writing ? Yes ,they are . / No ,they aren’t .
4)特殊疑问句及回答:特殊疑问词+be(am/ is/are)+主语+doing+其他成分
What are you doing ? We are playing (要求就提问内容具体回答).
2. 缩写形式如下:
I am---I’m You are---You’re He is---He’s She is---She’s
It is---It’s We are---We’re They are---They’re
3.说明: 不是所有动词都能用现在进行时态的,如：
see、like、want、know 等动词往往都不用进行时态．
四．用法：
1.表示现在( 指说话人说话时) 正在发生的事情．往往与 now,at the moment,just 等副词连用,以示强调．
We are waiting for you. What are you doing? Some one’s knocking at the door．
2.正在进行着的动作可视为未完成的动作：
He’s talking to his friends in the classroom.
可用 still 一词强调动作的持续性
He’s still talking to his friends in the classroom.
3. 表示长期的或重复性的动作,说话时动作未必正在进行．
Mr. Black is writing another article.
Don’t take that book away. Your father’s using it.
She is learning piano under Mr. Black.
4.现在进行时可用来表示不会长期发生的动作或情况,或被认为在短期内正在进行的动作或存在的情况：

5.现在进行时也可以用来表示当前的动向：
People are becoming more and more beautiful these days.
6. 表示渐变的动词有：become,turn,get,grow,run,go,begin等．
The leaves are turning brown.
It’s getting colder and colder.
7.与always,constantly,forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩．
You are always changing your mind.
8. 现在进行时(以及 be going to）可以表示为将来安排好的活动和事件 We’re spending next winter in China. 用arrive,come,go,leave 等动词的现在进行时描写行 程安排,也通常有“将到达”和“将离去”的意思： He’s arriving tomorrow morning.

动词过去式的构成：
(1)规则动词过去式的构成有四条规则：
①一般在动词原形末尾直接加上-ed。如：look-looked。
②以不发音的字母e结尾的动词，去e再加-ed。如：live-lived。
③末尾只有一个辅音字母的重读闭音节，先双写这个辅音字母，再加-ed。如：stop-stopped。
④末尾是辅音字母+y结尾的动词，先变y为i，然后再加-ed。如：study-studied。
(2)不规则动词的过去式需特殊记忆。
am(is)-was, are-were, go-went, come-came, take-took, have (has)-had
read-read, make-made, see-saw, go-went, eat-ate,
III. 一般过去时的几种句型

否定句结构为：主语+did not (didn't)+动词原形+其它。如：He didn't go to the toy store yesterday. 他昨天没去玩具店。
一般过去时的一般疑问句的构成：

1) -Did you go to Beijing last week? -Yes, we did. (No, we didn't.)
2) -Did you meet the businessman before? -No, I didn't. (Yes, I did.)

1) -What did you do last night? -I did my homework.
2) -Where did you go last week? -I went to Shanghai with my parents.
一般过去时口诀
一般过去时并不难，表示过去动作、状态记心间。
动词要用过去式，时间状语句末站。
否定句很简单，didn't 站在动词原形前，其它部分不要变。
一般疑问句也好变，did放在句子前，主语、动词原形、其它部分依次站。
特殊疑问句也简单，疑问词加一般疑问句记心间。
最后一条请注意，动词过去式要牢记。
小朋友们口诀记，学会一般过去时没问题。
