L6 + L7 文法-假設語氣+倒裝句

假設語氣 + 倒裝句

※假設語氣之時間順序：

過去完成→→→→過去式→現在式→未來式

1. 對未來不確定的假設：

If + S + beV/V現在/助V, S + 一般V/助V + V原

可根據事實而改變

※假設語氣沒有未來式, 所以現在式代替未來式

Ex: (1) If I study hard, I will get good grades.

倒裝：

1.去If

2.一般V找助V幫助 (如果本身有beV/助V就直接提至S之前)→類似疑問句寫法

3.主要子句不改變, 改變的是有If那一句

疑問句：

I am a good student. → Am I a good student?

I study English. → Do I study English?

I can study hard. → Can I study hard?

假設+倒裝句型：

If + S + beV/V現在/助V, S + 一般V/助V + V原

→BeV + S + ~, S + 一般V/助V + V原

→Do + S + V原, S + 一般V/助V + V原

→助V + S + V原, S + 一般V/助V + V原

句字改寫：

(1)If I am a good student, I can get a lollipop.

→Am I a good student, I can get a lollipop.

(2)If I study hard, I will get good grades.

→Do I study hard, I will get good grades.

(3)If the train should be delayed, please let me know at once.

→Should the train be delayed, please let me know at once.

2. 與現在事實相反：

If + S + were/V-ed, S + would/might/could/should + V原

※beV一律用were, 即使是I, she, he

Ex:(1)If I were you, I would kiss her.

(2)If I kissed her, she might love me more.

假設+倒裝句型：

If + S + were/V-ed, S + would/might/could/should + V原

→Were + S + ~, S + would/might/could/should + V原

→Did + S + V原, S + would/might/could/should + V原

句子改寫：

(1) If I were you, I would kiss her.

→Were I you, I would kiss her.

(2)If I were a nurse, I should be patient.

→Were I a nurse, I should be patient.

(3)If I kissed her, she might love me more.

3. 與過去事實相反：

If + S + had + p.p, S + would/might/could/should + have + p.p

Ex:(1)If I had enough money, I would have bought this house.

假設+倒裝句型：

If + S + had + p.p, S + would/might/could/should + have + p.p
