2024年八年級(jí)英語上冊重點(diǎn)時(shí)態(tài)梳理總結(jié)：現(xiàn)在進(jìn)行時(shí)

1. 動(dòng)詞變化：現(xiàn)在進(jìn)行時(shí)由“am /is /are＋動(dòng)詞現(xiàn)在分詞”構(gòu)成。加-ing的規(guī)則如下：

(1)一般在動(dòng)詞原形末尾加-ing。如：

stay-staying do-doing

listen-listening suffer-suffering

work-working spend-spending

look-looking

(2)以不發(fā)音的字母e結(jié)尾的動(dòng)詞，先去掉e，再加-ing。如：

make-making take-taking

give-giving ride-riding

please-pleasing refuse-refusing

close-closing operate-operating

(3)以一個(gè)輔音字母結(jié)尾的重讀閉音節(jié)詞，先雙寫這個(gè)輔音字母，再加-ing。如：

put-putting sit-sitting

run-running win-winning

begin-beginning

2. 現(xiàn)在進(jìn)行時(shí)的用法

(1)表示說話時(shí)正在進(jìn)行或發(fā)生的動(dòng)作，這時(shí)可以不用時(shí)間狀語，也可以和now, at present, at the moment等時(shí)間狀語連用。有時(shí)用一個(gè)動(dòng)詞，如look(看)，listen(聽)。

eg: What are you reading now?

Listen! Someone is singing in the classroom.

(2)表示當(dāng)前一段時(shí)期的活動(dòng)或現(xiàn)階段正在進(jìn)行的動(dòng)作。

eg: They are working in a factory these days.

More and more people are giving up smoking.

(3)表示最近按計(jì)劃或安排要進(jìn)行的動(dòng)作。

現(xiàn)在進(jìn)行時(shí)有時(shí)可表示一個(gè)在最近按計(jì)劃或安排要進(jìn)行的動(dòng)作，即可以用來代替將來時(shí)。

eg: When are you leaving?

Are you going to Tibet tomorrow?

3. 現(xiàn)在進(jìn)行時(shí)的否定句和疑問句比較簡單。否定句在be(am, is, are)后面加not;疑問句把be動(dòng)詞移到主語前。

eg:

I am not working.

What are you reading now?

How are you feeling today?

The train isn’t arriving soon.
