小升初语法专项——现在进行时讲义+练习
一、定义
现在进行时用于描述当前时刻正在进行的动作或暂时存在的状态。它特别强调动作的“正在进行”这一特性,而不是一般性的行为描述。它强调动作的即时性和当前性,可以用来表达说话时正在发生的事情、当前一段时间内的活动、计划中的未来事件以及反复发生的令人烦恼的行为。
·描述此刻正在发生的动作:
示例: Look! The dog is chasing a cat. (看!那条狗正在追一只猫。)
She is cooking dinner right now. (她现在正在做晚饭。)
Look! The children are playing in the park. (看!孩子们正在公园里玩耍。)
·表示当前时间段内的临时状态:
示例: These days, I am working part-time at a local café.
(这些天,我在当地一家咖啡馆做兼职。)
We are staying at a friend's house this week because our apartment is being renovated. (这周我们住在朋友家里,因为我们的公寓正在装修。)
These days, I am staying with my grandparents.
(这几天,我住在爷爷奶奶家。)
·表达即将发生的计划(通常与表示将来的时间状语连用):
示例: They are flying to New York next Monday. (他们下周一将飞往纽约。)
My sister is getting married in June. (我姐姐六月将要结婚。)
We are leaving for Beijing tomorrow. (我们明天出发去北京。)
·描绘不断重复且令人厌烦的行为(常带有情感色彩,如抱怨):
示例: He is always interrupting me when I'm speaking.
(当我讲话时,他总是打断我。)
Why are you constantly changing your mind (你为什么老是改变主意?)
He is always forgetting things. (他总是忘记东西。)
Why are you always coming late (你为什么总是迟到?)
·描述背景信息:
示例: While he was walking through the park, he saw an old friend.
(当他穿过公园时,看到了一位老朋友。)
As she was reading her book, the phone rang.
(当她在读书时,电话响了。)
二、结构
现在进行时的构成是“am/is/are + 动词的现在分词(-ing形式)”。根据主语的不同,选择不同的助动词:
·第一人称单数(I):am + 动词-ing
示例:I am writing a letter.
·第三人称单数(He/She/It):is + 动词-ing
示例:She is reading a book.
·其他人称(You/We/They):are + 动词-ing
示例:They are playing basketball.
【注意】
·对于疑问句,将助动词提前。
示例: I am listening to music.
Are you listening to music
Yes, I am. / No, I’m not.
·对于否定句,在助动词后加not。
示例: He is watching TV.
He is not watching TV.
动词的现在分词变化规则
·一般情况:直接加-ing。
示例:walk → walking talk → talking
·以不发音e结尾的单词:去掉e再加-ing。
示例:make → making have → having
·重读闭音节,末尾只有一个辅音字母:双写最后一个字母再加-ing。
示例:sit → sitting run → running
·特殊情况:以-ie结尾时,先将-ie变为-y再加-ing。
示例:lie → lying (躺) die → dying (死亡) tie → tying(平局)
