was = is,am (you use " was " in past tense)
were = are (you use " were " in past tense)
he,she,it use" were/are "
I,we,they,we use " was/is/am "

you can use I was... when you are just saying something.
you can use I were... when you are compare with something that is plural.

單數和用過去式, 就要用was. eg. i was a boy ten years ago.



眾數和用過去式, 就要用were. eg.we were children ten years ago.



但有例外, 在沒有可能的情況下, 單數也用were.



eg. if i were you, i will buy it.

is/am/are:是的解釋, e.g..

I am a boy.(現在式黎的)

I am playing.(現在進行式)

He is swimming.(現在進行式)

was:(過去式)/(過去進行式)

If it is past tense(過去式), then
it funtions as (be),
am/is - was
are - were

if you want to say (if ... ,....)
e.g.
如果我是你,我會放棄!
If I were you, I will be give up.
係呢個情況,無論你係用is/am/are 都係用were,因為你講緊d冇可能發生的事

1) was 係verb-to-be 其中一款, 佢係is 的過去式。



Past tense (過去式)



e.g. She was very happy. 她很開心。



Past Continuous tense (過去進行式)



e.g. She was doing her homework when the door bell rang yesterday.



昨日當門鈴響起的時候, 她正在做家課。

2010-08-17 14:47:58 補充：
補充: 幾時用 was

另一個情況會用 was 係

當 main verb (這裏係 punish) 係用於被動型式 (同時又係過去式), 而 subject 係 he , she 或 it 其中一款

E.g. Last week, he WAS punished by his teacher

"Was"almost is using on"past continues tense"or"express sentiments
of variation"

1)Past continues tense

Vivian and I were doing homework together.

2)Express sentiments of variation

I was upset because my dog was death last night.

2010-08-17 14:50:43 補充：
Was is the past tense for am and is.
If you want to say something using am or is in past tense , was will be the right verb.

2010-08-17 14:50:53 補充：
For example , if you want to say " He is very nervous " in past tense (過去式) , then you should use " he WAS very nervous " because you have to change " is " to " was " .
Examples for was ,
1. I was nervous .
2. She was doing her exam.
3. He was at my house.

When was it published?
回答是
It was published in 2000.
WAS PUBLISHED 是it的被動詞，即是it是要被出版，它(一本書)不能自己出版自己。
因此
When did it published?意義上不成立因此沒有這種寫法的。

Last , 我推薦您一個非常不錯的英語學習網站，里面有很多非常不錯的學習資源，您能從中得到不少幫助：

我諗用中文答你會好一些。

首先is/am/are是動詞，意思係人都知。

然而eat又係動詞。

但一個句子又豈能有兩個動詞，中文都不可以啦。


因此每一個句子都只需一個動詞

例如他食蘋果>he eats apple.就可以了。不用is.


另外

is/am/are解是，後面大部份的時侯都跟名詞或形容詞

例如she is beautiful(形容詞).she is a student(名詞).


最後你問的is/was幾時用。其實好簡單was同is/am意思上是一樣的，但was係過去的動詞，表示事情己發生了。

Wrong.

You should write in this way:

He eats apple. OR He is eating apple.

"Is" and "was" are used before and adjective.

Example:

She is pretty.

He, she, it, these pronouns are third person singular pronouns, so verbs after them should be added the letter 's'.
'Was' is the past tense of be, usually were put after 'he', 'she' and 'it'.

For the sentence 'He is eat apple'. 'Eat' should change to 'eating' because it is an action happening now.

For the sentence 'He eat apple.' According to the first rule, 'eat' should be added the letter 's'.
