did,are,have

首先, did 係過去式, 不過are and have 係現在式。did ge 現在式係do.
佢地基本ge 解釋係....
did(do) = 做
are = 是
have = 有

而佢地後面要跟d 咩就要視乎佢地係句子用面係咩性質, 因為呢3 個words 都可以係main verb or 輔助詞。
1. did
---> 如果did 係一個main verb ge 話, 佢ge 解釋會係"做 "==> 後面要跟subject/ noun
~e.g.: We did homework yesterday.( 我們昨天做功課)----留意: did 係過去式
We do homework.(我們做功課)----呢句係用現在式
* 係2 句句子入面, homework 係一個noun, "did " 係main verb, 因為句子要表達同強調ge 係"做 " 功課呢個動作, 所以did 係main verb。
---> 如果did 係一個輔助詞, 作用多數係用輔助表達, 所以佢係無一個獨立ge 解釋===> 後面多數係跟verb, 而且係一個infinitive ge verb, 即係果個verb 係係現在式ge 時態
~e.g. We did not go Mary's home yesterday.( 我們昨天沒有去mary 屋企)
* 句子入面did 係一個輔助詞, 輔助表達"沒有去 "呢個動作, 因為英文文法入面無go not 呢個講法, 所以要用did/do/does+ not + main verb 黎表達"沒有 ". 又因為句子要表達同強調ge 係"沒有去 " 呢個動作, 所以go=去係main verb, 所以did 只係輔助詞。

2. are
---> 如果are 係一個main verb ge 話, 佢ge 解釋會係"是 "==> 後面要跟subject/ noun
~e.g.: We are girls.( 我們是女孩子)
* 句子要表達同強調ge 係"是 " 女孩子, 而girls 係noun, 所以are 係main verb。
---> 如果are 係一個輔助詞, 作用多數係用輔助表達進行式ge 時態, 所以佢係無一個獨立ge 解釋===> 後面多數係跟verb+ing, 即係果個verb 係ge 進行式時態
~e.g.: We are having dinner.(我們正在吃晚飯)
* 句子要表達同強調ge 係"食緊 "晚飯, 所以have 先係main verb, 但係由於句子又要同時表達果個動作係進行中, 即係食緊晚飯, 所以要用"are " 黎輔助表達進行式ge 時態, 變成are having dinner.

3. have
---> 如果have 係一個main verb ge 話, 佢ge 解釋會係"有/擁有 "==> 後面要跟subject/ noun
~e.g.: We have 10 dollars. (我們有十元)
* 句子要表達同強調ge 係"有 " 十蚊, 所以have 係main verb.
---> 如果have 係一個輔助詞, 作用多數係用輔助表達現在完成式時態(present perfect tense) ==> 後面係跟一個係過去分詞 ge verb
~e.g.: We have finished our work.(我們已經完成我們的工作了)
* 句子要表達同強調ge 係"完成 " 呢個動作, 所以finish 先係main verb, 但係句子又想同時表達動作現成已經完成了, 所以加個have 黎輔助表達.

注意:
# did 係過去式, are and have 係現在式.
# 因為subject 係"we ", 所以先用are and have, 如果係he/she/it 係要用"is " 黎代替"are ", "has " 黎代替"have ".
