✔ 最佳答案
Conditional 有四種1.最簡單的一種: 每次發生某事情時, 必會做另一件事情
如: 如果下雨, 我會帶遮.
If it rains, I carry an umbrella. (If 可用when/whenever代替)
Form: 前後兩句都用現在式.
2.Future Possible Conditional
只要(將來)某事情發生, 我會做另一件事情.
如: 如果明天下雨, 我將會帶遮.
If it rains tomorrow , I will carry my umbrella.
I will be very surprised if I pass my English test.
Form: If 句用現在式動詞, 另一句用will/can/should/must/may/might + 動詞.
If 可以用在一句句子開頭, 那麼兩句句子中間有逗號.
或用在中間, 連接兩句句子, 那麼不用逗號.
3.Present Unreal Conditional
假設現在發生某事, 我就會怎樣. (事實現在不可能發生此事)
如: 如果我係你, 我會同我老細講. (事實我唔可能係你)
If I were you, I would talk to my boss.
If it were raining, I would call a taxi. (但事實無落雨)
*** be 在這個情況下, 不論係 I, he/she/it 都用were 而不是was ***
Form: If 句用過去式動詞, 另一句用would/could/may/might + 動詞.
4.Past Unreal Conditional
假設以前發生過某事, 過去/現在/將來就會怎樣.
如:
If we had bought that house in 1980, we could sell it now for a lot of money. (影響現在)
If they hadn’t come to the United States, they would have gone to Canada.
(兩句都過去, 佢地無去加拿大, 而來左美國)
If she had continued studying law, she would be graduating next June. (影響將來)
(因為佢過去無繼續讀law, 所以呢個六用佢唔會畢業)
Form: If 句用past perfect(過去現成),
另一句用would have/could have/might have 或者 would/could/might.

Conditional Sentences / If-Clauses Type I, II und III
Conditional Sentences are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.
Conditional Sentence Type 1
It is possible and also very likely that the condition will be fulfilled.
Form: if + Simple Present, will-Future
Example: If I find her address, I’ll send her an invitation.
Conditional Sentence Type 2
→ It is possible but very unlikely, that the condition will be fulfilled.
Form: if + Simple Past, Conditional I (= would + Infinitive)
Example: If I found her address, I would send her an invitation.
Conditional Sentence Type 3
→ It is impossible that the condition will be fulfilled because it refers to the past.
Form: if + Past Perfect, Conditional II (= would + have + Past Participle)
Example: If I had found her address, I would have sent her an invitation.
Exceptions
Sometimes Conditional Sentences Type I, II and III can also be used with other tenses.
