【第一篇:一般將來時】
一般將來時主要用于:
表示將要發(fā)生的動作或情況
e.g. Tom will have a bike of his own.
與這個時態(tài)連用的時間狀語常用:
tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般將來時態(tài)與其它結(jié)構(gòu)表將來情況的區(qū)別:
一般將來時態(tài) :主要從時間的角度表將要發(fā)生的動作或情況。
be going to 結(jié)構(gòu) :①表(主觀上)打算或準(zhǔn)備做某事時。 ②表有發(fā)生某事的預(yù)兆時。
e.g. They are going to have a competition with us in studies. It is going to rain.
據(jù)以上區(qū)別,故下面一句是錯的:
I am going to be eighteen years old next year.
應(yīng)改為: I shall be eighteen years old next year.
be about to do sth 結(jié)構(gòu) :意為"剛要做某事"、"馬上要做某事"強調(diào)時間之緊迫性。
e.g. We are about to discuss this problem.
【第二篇:過去進(jìn)行時】
過去進(jìn)行時主要用于:
表示過去某個時刻或階段正在進(jìn)行的動作。
e.g. At that time she was working in a PLA unit.
那時她在解放軍某部工作。
What were you doing this time yesterday?
與這個時態(tài)連用的時間狀語常用:
at nine o`clock, this time last night, these days, at that time 等。
用 when 引導(dǎo)的時間狀語從句表示主句的動作正在進(jìn)行的時間。
e.g. When he came in, I was reading a newspaper.
注:
1 、 while 引導(dǎo)時間狀語從句敘述過去的動作時,從句常用過去進(jìn)行時。
e.g. I read a magazine while I was waiting for the bus.
2 、 when 用作并列連詞,意為"這時",連接兩分句時,第一句多用過去進(jìn)行時。
e.g. I was reading a newspaper when he came in.
一般過去時與過去進(jìn)行時的區(qū)別:
一般過去時:強調(diào)過去某一時間開始或完成的動作。
過去進(jìn)行時:強調(diào)過去某一時間正在進(jìn)行的動作。
試區(qū)別下面兩句: We were building a reservoir last winter.
去年冬天我們在修建一座水庫。(可能尚未建成) We built a reservoir last winter.
去年冬天我們修建了一座水庫。(已經(jīng)建成)
【第三篇:現(xiàn)在進(jìn)行時】
現(xiàn)在進(jìn)行時主要用于:
1 、表示現(xiàn)在或現(xiàn)階段正在進(jìn)行的動作。
e.g. Listen, someone is crying.
What are you doing these days?
2 、代替一般現(xiàn)在時,表示經(jīng)常性動作或狀態(tài),而含有某種感情色彩。
e.g. How are you feeling today?
你今天感覺怎樣?(顯得親切)
He is doing well in his lessons.
他的功課很好。(贊揚)
You are always boasting.
你老愛吹牛。(厭煩)
3 、動詞 go, come, leave, arrive 等表將要發(fā)生的動作時。
e.g. They are leaving for Shanghai.
與這種時態(tài)連用的時間狀語常有:
now, these days, recently, this week 等。
