用於以下五種情况
1.
To tell others you are in the middle of doing something
正在進行或發生的動作
e.g.
He is working right now, so can you call
later?
What are you doing？
It is raining.
Used with the following adverbs of time: 通常用於有以下副詞出現時
now, at the moment, at this moment, at
present, currently, for the time being
Non-progressive
verbs:
有些動詞一般不能/宜用于現在進行時，因它們表示狀態/感覺，不能表示正在進行的動作：
love, hate, want respect, admire, like,
dislike, value, desire, (verbs of emotion and feeling感覺)
know, think, remember, understand, expect,
can't forget , recall,see, realize, trust,perceive...(mental activity思念活動)
look,
hear, feel, ...(unintended or
involuntary action不隨意活動)
watch, listen...(intended or voluntary
action)
belong, owe, own , borrow..(verbs of
property)
seem, appear, look, taste, smells,
sounds....(linking verbs)
不過有些這類動詞用進行時是有別的意思的！
e.g
She looks tired. 表示狀態
She is looking at a bird. 表示動作
The food smells nice. 表示感覺
He is smelling the flowers. 表示動作
The juice tastes good. 表示感覺
I’m tasting the wine. 表示動作
She has two sisters. 表示狀態
She is having lunch. 在吃午飯---表示動作
I have a dog. (= own有)表示狀態
We are having a walk.= we are walking. 表示動作
有些表示動作的動詞有時反而表示狀態，這時不宜用進行時
e.g
My house stands by the river.
The hut sits in the forest.
The town lies before us.
The coat dosen’t fit me.
He is standing on a chair.
They are sitting on the grass.
She is lying on the beach.
He is fitting the pieces together.
有些表示極短暫動作的動詞也不宜於用進行時
e.g
declare
recognize
jump
nod
但有時用於進行時，則表示反复做某動作
e.g
He is jumping up and down.
The old man is nodding his head.
2.
To denote a more temporary action or arrangement
---one main use of the continuous tense(present,
past, future) is to tell that something is temporary. 表示一時的動作/安排
e.g
John is teaching us grammer and it is
boring. (temporary)
比較以下一句
Bill teaches us English and he teaches very
well. (permanent action) ( Bill 才是我們的英文老師)
Is Mr Bill very sick? He hasn't been around
for quite some time. What happened to him? Mr Tak took over the Maths class,
and he is teaching it well. He told us that he used to be a Maths major at the
university.
Be 在一般情況下不能用於進行時，有時卻可以這樣用來表示一時的表現
e.g
Bob is being silly.
You’re being very clever today.
The children are being very quiet.
You’re being childish.
I am not being slow. I’m being careful.
3.
ALWAYS + continuous tense
often used with adverbs such as always,
repeatedly, continuously, forever to
tell an often repeated action.表示經常性動作，表示厭煩或贊美等情緒
e.g
He’s always making that mistake. (不耐煩)
Social workers are always trying their best
to help their clients.(贊賞)
He is constantly changing her mind.(不滿)
如只說明事實，則用一般現在時
e.g
He does fine works at school. (只說明事實)
He is doing fine works at school. ( 贊賞)
How do you feel today？(只明事實)
How are you feeling today？(關切)
She often complains of his job. (只說明事實)
She is always complaining of his job.( 厭煩)
有些靜態動詞也可用現在進行時
e.g
I’m hoping you’ll all come.(表示殷切希望)
I’m always hearing strange stories about
him.
I am forgetting that I promised to ring him
tonight.
還有少數動詞用兩種時態意思也差不多
e.g
I wonder(am wondering ) whether you could
give me some adv ice.
Does your leg hurt ( Is your leg hurting？)
I write (am writing ) to inform you that
your mother is ill.
I don’t hear ( am not hearing) as well as I
used to .
Now
