[一号档案] 现在进行时的构成形式
现在进行时在其构成形式为:be+动词-ing形式,be是助动词,它有人称和数的变化,即要根据主语选用am,is或are。现在分词的构成方法如下:
1. 一般在动词后直接加上-ing。例如:work→working, do→doing, talk→talking, drink→drinking
2. 以不发音e结尾的动词应先去掉e然后加-ing。例如:write→writing, skate→skating
3. 以ie结尾的动词,变ie为y加-ing。例如:lie→lying, die→dying
4. 以重读闭音节结尾的动词,如果该单词末尾只有一个辅音字母,则应先双写该辅音字母,再加-ing。例如:put→putting, sit→sitting
[特别提醒]要双写的动词一般满足下面三个条件:①单词末尾的字母结构是“辅+元+辅”;②上述结构中的元音字母发短元音;③单词末尾的音节重读。例如:run→running, begin→beginning
I am doing my homework. 我现在正在做家庭作业。
He/She is doing his/her homework. 他/她现在正在做家庭作业。
We/They are doing our/their homework. 我们/他们现在正在做家庭作业。
[二号档案] 现在进行时的句型变化
在现在进行时的肯定句中be动词当然应在主语的后面,但在疑问句和否定句中情况就不同了,应将be移到主语前构成疑问句,在be后加上not构成否定句。例如:
They are playing beach volleyball. →Are they playing beach volleyball?
→They are not playing beach volleyball.
Lisa and Tim are waiting for a bus. →What are Lisa and Tim waiting for?
→Lisa and Tim are not waiting for a bus.
[三号档案] 现在进行时的基本用法
每一种时态都有其最基本的用法,现在进行时一般表示现在或现阶段正在进行的动作。例如:
Bob and Mike are playing soccer now.
鲍勃和迈克现在正踢足球。(踢足球的动作现在正在发生。)
This month Dad is writing a book. 这个月,爸爸在写一本书。
(在现阶段this month, 写书动作一直在发生。)
提示:表示位置移动的动词,如leave, move, go, come, start, begin等也常用现在进行时表示将要发生的事,而不表示动作现在正在进行。例如:
Next week my family is moving to Beijing.
下周,我家就要搬到北京去了。(搬的动作并非现在发生,而将在下个月发生。)
My aunt is leaving for Shanghai at eleven o’clock tomorrow morning.
明天早上十一点我婶婶将离开去上海。
[四号档案] 现在进行时的使用场合
1. 当句中出现的表示时间的词是now, at the moment (此刻、现在)等时,表示句子要说明的是现在正在发生的事,动词应用现在进行时。例如:
Linda’s brother is watching TV in his bedroom now.
琳达的哥哥现在正在他的卧室里看电视。
We’re far from home. What are our parents doing at the moment?
我们现在远离家,我们的父母此刻在干什么呢?
2. 当句子出现的时间状语是these days, this week, this month等时,如果句子所要表达的意义是在这一阶段正在发生的事,则动词应用现在进行时。例如:
These days we are learning computer. 这些天我们在学电脑。
They’re having a test this week. 这一周他们在进行一次考试。
Mr Liu is visiting our village this month. 这个月刘先生在我们村访问。
3. 在句中出现了Look, Listen, Can’t you see? 等暗示词时,说明后面谓语动词的动作正在发生,该动词应用现在进行时。例如:
Look!Maria and Tom are dancing under the tree. 看!玛丽亚和汤姆正在树下跳舞。
Listen!Our English teacher is singing the popular English song.
听!我们英语老师正在唱那首流行的英文歌曲。
Many children are swimming in the river. Can’t you see?
许多小孩在河里游泳,你难道看不见吗?
4. 注意根据上下文的暗示,句子的谓语动词可能应用现在进行时。例如:
Where is Mr Wang? 王先生在哪儿?
Oh, he is reading a newspaper in the office. 噢,他正在办公室看报。
(问句询问王先生在哪儿,应说明他现在在哪儿,故答句应说明他现在正在做的事,用现在进行时。)
Is that boy Jack? 那个男孩是杰克吗?
No. Jack is doing his homework in the classroom. 不是,杰克正在教室做作业呢。
(答句中说明杰克做作业的情况应发生在现在,应用现在进行时。)
提示:对于see, know, want, like, hear等表示情感状态、知觉认识或愿望的动词,一般在句中不能用现在进行时态,而应用一般现在时。例如:
Now many students like reading Harry Potter. 现在有许多学生喜欢读《哈利•波特》。
