1.Grammar
The present continuous tense
1.We use the present continuous tense to show that something is happening now.
2.We also use the present continuous tense to talk abotemporary situations.ut
It is often used with:
now,at the moment,right now,look,listen
eg:
We are stay at Peter's house now.
The students are listening to Miss Li carefully.
Is Linda doing her homework at home right now?
What are you doing at the moment?
Listen,the singer is singing on the stage.
Look,Michael is playing the guitar.
Why is he crying?
3.現在進行時還表示當前一段時間或現階段正在進行(但說話時不一定在進行)的動作。常與this week,these days等時間狀語連用。
eg:
We are planting trees this week.
The students are working hard these days.
We are making model planes these days.
4.描述圖片中的人物的動作,也為了表達更生動,此時也常用現在進行時。
eg:
Look at the picture,the children are flying kites in the park.

有些動詞從結構來看是現在進行時,但卻是表示將要發生的事,而不表示動作現在正在進行。這些動詞往往是一些表示位置移動變化的動詞,
如:go,some,leave,fly,move,begin,arrive,stay,return等。
Next month my family is moving to Beijing.
下個月,我家就要搬到北京去了。(搬的動作并非現在發生,而將在下個月發生。)
My aunt is leaving for Shanghai at eleven o'clock tomorrow morning.
明天早上十一點我嬸嬸將離開去上海。
在實際運用時,現在進行時常用以下幾種情況:
(1)當句子中有now,at the resent,at the moment(現在)時,常表示動作正在進行,或者告訴你一個準確的現在時間,這時要用現在進行時。如:
They are playing basketball now.現在他們正在打籃球。
(2)以look,listen等暗示性詞語開頭的句子,提示我們動作正進行,這是要用現在進行時。如:
Listen!She is singing an English song.聽,她正在唱英語歌。
(3)當局中出現的時間狀語是today,these days,this week,this month等時,如果句子所要表達的意義是在這一階段正在翻身的事,則動詞應用現在進行時。如:
We are making model planes these day.這些天我們在做飛機模型。
(4)描述圖片中的人物的動作,也為了表達更生動。此時也常用現在進行時,如:
Look at the picture.The children are flying kites in the park.
看這幅圖,那些孩子正在公園放風箏。
(5)在口語中表示主語計劃將要作的動作。
They are leaving for New York tomorrow.明天他們將要動身前往紐約。
Is your brohter departing soon? 你的兄弟很快就要啟程嗎?
這類情況常與come來,go去,leave離開,depart離開,arrive到達,stay逗留,start開始等動詞連用。所用的動詞必須是動作而不是狀態,主語必須是人。
