【三大子句】5分鐘學會副詞子句｜簡化副詞子句的方法

I like to eat cake.
我喜歡吃蛋糕。

While Mom was taking a shower. (Ｘ)
當媽媽在洗澡時...（語意不完整）
沒有說完「當媽媽在洗澡時」究竟發生什麼事

因此應該要改寫成⮕
While Mom was taking a shower, the bell rang. (Ｏ)
當媽媽在洗澡時，電鈴響了。

How can you say you don't like him when you've never even met him!
你連他都沒見過，怎麼能說不喜歡他呢！
→ 副詞子句 when you've never even met him 修飾整個主要子句，補充說明了「你沒見過他」的這個資訊。

★如果去除副詞子句，僅留下主要子句，句構依然完整，如下：
How can you say you don't like him!
你怎麼能說不喜歡他呢！

例句：While I was in America, I went to see the Statue of Liberty.
當我在美國時，我去看了自由女神像。

★開始簡化流程

1. 確認主詞相同：「副詞子句」的主詞和「主要子句」的主詞皆為 I （我），確認主詞相同。
2. 省略主詞：While I was in America, I went to see the Statue of Liberty.
3. 動詞變形：While being in America, I went to see the Statue of Liberty.（動詞為主動，變形為 Ving）
4. 省略 being：While being in America, I went to see the Statue of Liberty.
5. 省略從屬連接詞：while 可省略，但此句建議保留，語意較為清楚。

★簡化後的比較
原句：While I was in America, I went to see the Statue of Liberty.
簡化後：(While) in America, I went to see the Statue of Liberty.
