-- Present Simple （現在式）
最簡單的時態，它的用途有三種：

1 用以表達一些重覆的動作或習慣
2 表示一種永恆不變的情況，事情
3 表示真理


-- Present Continuous Tense （現在進行式）

1. 表示一個與說話時同步進行的動作
2. 表示一個發生時間比現在相差不遠的動作
3. 表示一個時常重復又惹人煩厭的動作或事情
4. 表示一個正在轉變中的事件或計劃了而將進行的事情

--Present Perfect （現在完成式）
1. 當說及一些事件發生於以前，並繼續進行至現在，我們都可以使用 Present Perfect Tense 或 Present Perfect Continuous Tense
2. 當強調一個動作我們做了多少次或發生次數，我們會用 Present Perfect Tense
3. 當一個動作於過去發生，持續到現在，並有可能會繼續發生至將來


-- Simple Past （過去式）
表達一個過去及已經結束的動作，而這個動作必須給予一個清楚的時間。簡單而言，就是如果我們在知道時間的情況下，我們會用 Past Tense，相反如果不知道時間，我們會用 Present Perfect Tense，或 Past Perfect Tense，視乎情況。

-- Past Perfect Tense （過去完成式）

當我們想表達一個比 Simple Past Tense 更早發生的動作時，就會用上 Past Perfect Tense 或 Past Perfect Continuous Tense。


--Past Countiunous tense
動詞的過去進行時態的形態


--Simple future tense
將會發生的事。不太肯定會will，十分肯定會be going to。這些詞後的字不用加(s,ess,ed...)。問問題用will或shall，I 或we用shall，其餘用will。
