2024中考英语语法知识点--动词的时态(二)
现在进行时
一、知识点解析
1、用法:现在进行时表示现在或当前一段时间正在进行的动作。可以表示有计划的未来,也就是用现在进行时表示将来。
1.表示现在( 指说话人说话时) 正在发生的事情。
We are waiting for you.
我们在等你。
2.表示长期的或重复性的动作,说话时动作未必正在进行。
Mr. Green is writing another novel.
格林先生在写另一部小说。
(说话时并未在写,只处于写作的状态。)
3.已经确定或安排好的将来活动
I'm leaving for Beijing next week.我下星期去北京。(已经安排了)
We're flying to Paris tomorrow.我们明天飞往巴黎。(票已经拿到了)
2、构成:
1.主语+be(am, is, are)+现在分词。它的句型变化和be动词的句型变化一样,一般疑问句把be提前,否定句在be后加not。
2. 现在分词的构成
现在分词是在动词后加上ing 构成。如:starting,working, coming, sitting 等。
(1)直接在谓语动词后加ing. 如:going, starting, working.
(2)去掉词尾不发音的e,再加ing. 如 leaving,dining.
注意:如果单词结尾的e发音,则不能去掉,也直接加ing. 如:see -seeing/agree - agreeing .
另外,有少数动词比较特殊,请用心记住:如:lie - lying/die - dying/tie - tying.
(3) 对于重读闭音节词,双写末尾字母再加ing. 例如:sitting, beginning.
这一条规律,必须要弄清什么是“重读闭音节”。下面再举一些双写的例子:
run - running
stop - stopping
cut - cutting control – controlling
二、例题展示
1. -Listen, what’s the noise?
- My brother _______ the programme of the World Cup in the sitting room.
A. watches B. is watching C. has watched
答案为 B。 本题考查的是现在进行时,从上文Listen来看,应该是现在正在发生的事情。
2.—Peter, I haven’t seen you for a long time.
—Oh, I _______ a book these days.
A. am writing B. have written C. wrote
答案为A。本题考查现在进行时表示当前一段时间正在进行的动作的用法。
