在完整句子中，主要動詞只能得一個。除非引入了附句子或用連接詞加入了另一個完整句子。在主要動詞前的動詞叫輔助動詞。它們沒有字意，只是輔助性質，不要強加中文意思影響文法。也不要因為輔助動詞有時可作主要動詞 (有字意) 而被混淆。

1. 動詞有分 1 連接動詞 (表示主詞是什麼，最常見的有 'be'* )， 2 動作動詞 (表示主詞做什麼) 。要構成問句或否定句，主要動詞(只限動作動詞)前加輔助動詞 do。

       例句： Do you know how to do this? / I do not know.

2. can 是情態動詞 (輔助動詞的一種) 。注意：情態動詞後的主要動詞必須是原形 (跟簡單現在式一樣，而且不用加 s 協調主詞)。

       例句： I can help you do it.

3. 要構成某種時態：

       - 進行式 (現在/過去) ：(be) + verb-ing (present participle現在分詞)

          I am/was swimming.

       - 完成式 (現在/過去) ：(has/have/had) + verb (past participle過去分詞)

          I have/had swum.

4. 被動句式：(be)+ verb (past participle過去分詞)

       The work was done by someone else.

[* be 像孫悟空，多變： be, is, am, are, was, were, being, been]
