小学生微试题
一)现在进行时
1.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.
2.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?
(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:
What’s your brother doing these days? He’s studying English at Oxford University.
(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.
3.小学英语句型结构:助动词 be ( am / is / are ) +现在分词.
1)肯定句:主语+be(am/ is/are)+doing+其他成分
I am singing . They are writing .
2)否定句: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).
4. 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
5.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.
通常在句子中有以下的词:now, look, listen, at present.
如:1. I am listening to the music now.
2. The students are drawing pictures now.
3. Listen! She is singing .
4. Look! Mr Li is riding a bike.
Be动词+动词的ing形式两者缺少其中任何一种都不可以构成现在进行时。
3.动词现在分词构成:
1) 正常变化是在动词原型后加ing 如: read----reading ; drink---drinking ; eat---eating ;
2) 以e结尾的动词,去掉e再加ing 如:
write ---writing ; make--- making ; ride---riding ;
3).重读闭音节( 只有一个元音字母,而其后跟有一个辅音字母时)要双写结尾的辅音字母再加ing sit---sitting ; swim--swimming ; put---putting ; run—running
