新仁爱英语七上Unit4现在进行时的练习
一、概念
现在进行时表示此时此刻正在进行或发生的动作,强调动作在说话的瞬间正在进行。
例:She is reading a book.(她现在正在看书。)
二、结构:be动词(am/is/are)+ 动词的现在分词(v.-ing)
例:I am running.
He is singing.
You /They/We are dancing.
→否定形式:在be动词后加 not,即 主语 + be + not + v.-ing
例:She is not(isn't)watching TV.
→一般疑问形式:将be动词提到句首,即 Be + 主语 + v.-ing?
例:Are you listening?
三、常用的时间标志词
now、look、 listen、at the moment(此刻)
四、动词-ing形式的构成规则:
1. 一般情况下,直接加 -ing
例:play → playing;read → reading;cook → cooking;watch → watching
2. 以不发音的字母e结尾的动词,去e加 -ing
例:dance → dancing;write → writing;come → coming;take → taking
3. 以重读闭音节结尾,且末尾只有一个辅音字母的动词,双写末尾的辅音字母,再加 -ing
例:swim → swimming;run → running;sit → sitting;shop → shopping。
4. 少数特殊变化 如lie(躺)→ lying;die(死)→ dying。
