was/were and is/am/are

1.She was ate breakfast in this morning.-------錯
2.She ate breakfast in this morning.---------岩
1.I am listening to music.-------岩
2.I listen to music.---------岩

was /were 都係is/am/are ge 過去式, 同埋was/ were/ is/ am /are 都係be verb
即係"be " 呢個verb 其實係包括左was/ were/ is/ am /are, 而was /were 係過去式, is/ am/ are 係現在式
因為the meaning of "be"= 是, so the meaning of "was/ were/ is/ am /are " =是
一句句子入面只可以有一個main verb.

be verb ge 用法, 據我所知有2 個:
‧be verb 可以係一個main verb,
例如, she is beautiful.
This is a car.
I am a girl.
--> (當中ge "is/am " 是main verb, 表演"是" ge 意思, 同埋因為3 句句子入面講ge 野都係事實, 所以用現在式 , 而唔係過去式 )

‧不過be verb 都可以係一個輔助詞,
例如你ge 例子" I am listening to music."
-->( 當中"listen" 係main verb, 表達"聽 " ge 意思; 而"am " 係句子入面就係一個輔助詞, 表達出tense, " am listening" 強調我e+ "聽緊 " )
note: 係咁多種tense 入面, 只有進行式(現在進行式/ 過去進行式) 先要加be verb 做輔助, 表達佢ge action 係進行緊~~ 所以is,am,are後面係唔係一定要加ing, 就要睇情況, 如果係要表達ge 話就一定要加ing

就係因為咁, 所以你ge "I am listening to music. "同埋 "I listen to music. " 都係岩ge.
-->不過係唔同ge tense

不過因為" She was ate breakfast in this morning. " , 入面ge "ate " 係main verb, 而且佢要表達ge 係過去式, 而唔係現在進行式/ 過去進行式, 所以唔洗有be verb 做輔助表達, 所以係句子入面唔洗/ 唔可以有"was" 出現, 唔係就會有文法上面ge 錯誤( 一句句子有2 個main verb)

另外, be verb 亦會用於被動句式(passive voice) 作輔助表達出"被" 呢個動作
例如: The apple was eaten by Mary.
係度ge was 係用黎輔助表達出apple "被" mary 吃了.
而從個"was " 就睇得出, "吃" 呢個動作係過去式.
所以其實The apple was eaten by Mary.= Mary ate the apple.
note: 被動句式 ge verb 係be verb + p.p.---> 所以句子用係"was eaten ", 而唔係was ate, was eating...etc.

唔知呢d 係唔係你想要ge 野, anyway, hope those are useful to u:)

was同were是在past tense 才用
I,he, she, it 後用was , we,they,you 後用were.
was, were 用ing 或past participle(for passive voice)
所以She was ate breakfast in this morning is wrong,而eg. 2 應改為She ate breakfast this morning.
is, am ,are 後用ing 或past participle(for passive voice),
如閏用ing 是描述一個系正在做緊嘅動作
I 之後用am, he, she, it 之後用 is, we, they之後用 are
1 am listening to music and I listen to music both are correct, 視乎你想說(1)你正在聽音樂或(2)你是回答"Do you listen to music?"這問題

was/is 係當個 subject. (e.g Mary, She, Tom, He, It) 係 singular 個是用. singular means 一個人或一隻. 記住係 一個人或一隻動物.
---was 係 PAST TENSE.而 past tense 意思係 動作巳經做完.
---- is 係 present tense.而 present tense 意思係 動作還沒做.


were/are 係當個 subject (e.g ClassmateS, teacherS, parentS, bookS) 係 PLURAL 個是用. Plural means 一羣人 usually 有個s 係個字ga最尾.
自不過 were 係 PAST TENSE
而
are 係 PRESENT TENSE.
-----------例如: My classmates were very tired after the field trip.
My friends are very excited about the field trip.

am 係當個 subject is I( 記住 ONLY when the subject is I can use am) 而 又係 PRESENT TENSE ga 時侯用. 如果 I 要用 past tense ga 話 gum 就要用was la....

I am listening to music 意思係我已加 還 listening to music.
I listen to music 係一個 FACT.意思係 我聽音樂ga.


希望幫到你 la =]

In question 1(was & were) , example 1 is not correct . It is because after we used & ,we should put in the verb.But in example 2,you are correct.
& is use in past continue tense
I-------was
she-------was
he-------was
it---------was
we--------were
you--------were
they(Tom & Terry,Amy & Bella . ect)----------were

In question 2(is & am & are) , both 2 examples are correct because your :
examle 1 is a present continous tense
example 2 is present tense

Also after using is / am / are, remember to add after the verb (is eating)

Hope I can help you on it.
