【語法】so that於such that


一、such that 的用法

用法:表示「如此…以致於」

  • such 修飾名詞
  • that 引導結果狀語從句
  • 強調程度導致結果

結構:

such + (a/an) + 形容詞 + 名詞 + that + 結果句

例句:

  1. It was such a difficult test that I failed.

    • 翻譯:這是如此困難的考試,以致於我不及格。
    • such 修飾名詞 “test”
  2. He told such funny jokes that everyone laughed.

    • 翻譯:他講的笑話如此搞笑,以致於每個人都笑了。
    • such 修飾名詞 “jokes”
  3. They are such good friends that they share everything.

    • 翻譯:他們是如此好的朋友,以致於什麼都分享。
    • such 修飾名詞 “friends”

二、so that 的用法

有兩個完全不同的意思:

用法1:目的(以便)

主句 + so that + 目的句(常有情態動詞)

例句:

  • I study hard so that I can pass the exam.
    • 翻譯:我努力學習以便能通過考試。
    • 表達目的

用法2:結果(結果是)

主句, + so that + 結果句

例句:

  • He didn’t study, so that he failed the exam.
    • 翻譯:他沒學習,結果考試不及格。
    • 表達結果(但較少用)

三、核心區別

特點 such that so that
修飾對象 修飾名詞 連接兩個句子
主要意思 如此…以致於(強調程度→結果) 1. 以便(目的)
2. 結果是(結果)
結構 such + 名詞 + that 完整句 + so that + 完整句
能否省略that ❌ 不能 ⚠️ 有時可以省略

四、⚠️ 為什麼不能互換?

例子1:

such that(正確)

  • It was such a good movie that I watched it twice.
    • (這電影如此好,以致於我看了兩次。)
    • such 修飾名詞 “movie”

so that(錯誤)

  • It was so that a good movie I watched it twice.
    • 語法完全錯誤!

✅ 如果要用 so…that:

  • The movie was so good that I watched it twice.
    • so 修飾形容詞 “good”(不是名詞)

例子2:

so that(目的)

  • I’m saving money so that I can buy a car.
    • (我在存錢以便能買車。)
    • 表達目的

such that(不適用)

  • I’m saving money such that I can buy a car.
    • 完全不符合 such that 的用法

例子3:

such that

  • He has such bad eyesight that he needs glasses.
    • (他視力如此差,以致於需要戴眼鏡。)
    • such 修飾名詞 “eyesight”

so that(表示目的,意思完全不同)

  • He has bad eyesight so that he needs glasses.
    • 語法上勉強可以,但意思變成「他有壞視力是為了需要眼鏡」?
    • 邏輯不通!

五、什麼時候可能混淆?

只有在表示「程度→結果」時,可以用:

  1. such…that(修飾名詞)
  2. so…that(修飾形容詞/副詞)

不能用 so that

例子:

句型 例句 正確性
such…that It was such a hot day that we went swimming.
so…that It was so hot that we went swimming.
so that It was hot so that we went swimming. ❌ 意思變成「為了去游泳所以天氣熱」?邏輯錯誤!

六、📊 三種結構對比

表示「程度→結果」時:

1️⃣ such + 名詞 + that

  • He made such a big mistake that he got fired.
    • (他犯了如此大的錯誤,以致於被炒了。)

2️⃣ so + 形容詞/副詞 + that

  • His mistake was so big that he got fired.
    • (他的錯誤如此大,以致於被炒了。)

3️⃣ so that(表示目的/結果)

  • 目的:He worked carefully so that he wouldn’t make mistakes.
    • (他小心工作以免犯錯。)
  • 結果:He didn’t work carefully, so that he made mistakes.
    • (他工作不小心,結果犯了錯。)← 較少用,更常說 “so he made mistakes”

七、✅ 正確用法總結

such that 只有一個用法:

such + (a/an) + 形容詞 + 名詞 + that + 結果
= 如此…的(名詞)以致於…

so that 有兩個用法:

  1. 目的:動詞 + so that + can/could/will/would…
    = 為了、以便

  2. 結果:句子, so that + 結果句
    = 結果是(較少用)
