開始這一課之前,請先確認你已經理解:

3核心概念

① 這一課在學什麼?——「程度」加「結果」
生活裡我們常要表達「因為某個程度,所以有某個結果」:
• 箱子太重了,所以我搬不動。
• 他夠大了,所以他可以開車。
• 那本書有趣到一個程度,所以我讀了兩次。
這一課的四個句型,就是把這種「程度+結果」寫進一個句子的工具。
② too + 形容詞/副詞 + to V:「太……而不能……」
too 是「太」,後面接形容詞或副詞,再用 to V 帶出結果。在國中範圍,這個 to V 通常帶有「做不到」的否定意味。
• The box is too heavy to carry.(箱子太重,搬不動)
• My grandpa walks too slowly to catch the bus.(爺爺走得太慢,追不上公車)
受詞原則:如果句子的主詞本身就是 to V 的受詞,to V 後面不再重複受詞。上面的句子裡,「被搬」的正是主詞 the box,所以寫 to carry,不寫 to carry it。
🔑 常見錯誤:The box is too heavy to carry it. ❌——主詞 the box 已經是 carry 的受詞,再加 it 就重複了。
③ too...for + 人 + to V:「對某人來說太……」
如果做那個動作的人不是句子的主詞,就用 for + 人標明是誰。
• The tea is too hot for me to drink.(這茶對我來說太燙,喝不下)
• The question was too hard for us to answer.(這題對我們來說太難,答不出來)
④ 形容詞/副詞 + enough + to V:「夠……而能……」
enough 放在形容詞或副詞的後面,表示程度「足夠」,to V 帶出「因此做得到」的結果。
• Lily is old enough to go to school.(Lily 夠大了,可以上學)
• Ben runs fast enough to win the race.(Ben 跑得夠快,能贏得比賽)
如果 enough 修飾的是名詞,位置改成放在名詞前面:
• We have enough money to buy the tickets.(我們有足夠的錢買票)
🔑 最常考的陷阱:enough 的位置。修飾形容詞/副詞 → 放後面(old enough);修飾名詞 → 放前面(enough money)。He is enough old ❌ → He is old enough ⭕。
⑤ not...enough to 與 too...to 的反向關係
「不夠大到能做某事」可以換成「太(相反的形容詞)而不能做某事」:
• He is not old enough to drive. = He is too young to drive.(他年紀不夠大,不能開車 = 他太年輕,不能開車)
注意兩句的形容詞要換成反義詞(old → young),語意才會一樣。
⑥ so + 形容詞/副詞 + that 子句:「如此……以至於……」
so 之後接形容詞或副詞,再用 that 帶出一個完整的子句(有自己的主詞和動詞)來表示結果。
• I was so sleepy that I couldn't keep my eyes open.(我睏到眼睛睜不開)
• Ken studies so hard that he always gets good grades.(Ken 用功到總是拿到好成績)
💡 that 在正式書面與考試中通常保留;口語中有時會省略(如 I'm so tired I can't move.),但初學階段建議一律把 that 寫出來,避免與其他句型混淆。
⑦ such + 名詞 + that 子句:「這麼……的……以至於……」
such 之後接名詞(片語),再接 that 子句。名詞是單數可數時,such 後面要加 a/an:
• It is such a good idea that everyone agrees.(這主意好到大家都同意)
• She told us such an interesting story that we all want to hear it again.(她說的故事有趣到我們都想再聽一次)
名詞是複數或不可數時,such 後面不加 a/an:
• They are such friendly people that everyone likes them.(他們是這麼友善的人,大家都喜歡)
• It was such bad weather that we stayed home.(天氣這麼糟,我們只好待在家)
⑧ so vs. such 怎麼選?+重要例外:so many/much/few/little
快速判斷:看後面接什麼。
• 後面是形容詞/副詞 → 用 so(so tired、so hard)
• 後面是名詞 → 用 such(such a good idea)
例外:名詞前面如果有 many/much/few/little 表數量,要用 so 不用 such:
• There were so many people that we couldn't move.(人多到我們動不了)
• He made so many mistakes that he failed the test.(他錯這麼多,考不及格)
🔑 記住固定組合:so many + 複數可數名詞、so much/so little + 不可數名詞、so few + 複數可數名詞。這四個數量詞前面用 so,不用 such。
⑨ 句型互換:too...to ↔ so...that...can't;enough to ↔ so...that...can
兩組等義的改寫:
• He is too young to drive. = He is so young that he can't drive.
• He is old enough to drive. = He is so old that he can drive.
改寫時 that 子句要補出自己的主詞(he),並用 can't/can 表達「能不能」。
💡 補充:so that 連在一起時,常常表示「以便;為了」的目的(如 We left early so that we could catch the train.),與本課 so...that 表「結果」不同。國中階段兩種用法都會遇到,要看前後語意判斷。

4句型公式

① 太……而不能: S + V + too + 形/副 + (for + 人) + to V
The box is too heavy to carry.

too 之後接形容詞或副詞;to V 帶出「做不到」的結果。主詞同時是 to V 的受詞時,to V 不再重複受詞。

② 夠……而能: S + V + 形/副 + enough + to V
Lily is old enough to go to school.

enough 放在形容詞/副詞後面,to V 帶出「做得到」的結果。

③ 足夠的……可以: S + V + enough + 名詞 + to V
We have enough money to buy the tickets.

enough 修飾名詞時放在名詞前面。

④ 如此……以至於: S + V + so + 形/副 + that + S + V ...
I was so sleepy that I couldn't keep my eyes open.

so 接形容詞/副詞;that 子句是完整子句,有自己的主詞與動詞。

⑤ 這麼……的……以至於: S + V + such + (a/an) + 形+名詞 + that + S + V ...
It is such a good idea that everyone agrees.

單數可數名詞要加 a/an(母音開頭用 an);複數與不可數名詞不加。

⑥ 等義互換: too + 形 + to V ↔ so + 形 + that + S + can't + V
He is too young to drive. = He is so young that he can't drive.

too...to 換成 so...that 時,that 子句要補主詞,並用 can't;…enough to 換成 so...that 時則用 can。

5基礎例句

規則①②:too...to 與 too...for + 人 + to V

The box is too heavy to carry.
箱子太重,搬不動。
分析:主詞 the box 就是 carry 的受詞,所以 to carry 後面不再加 it。
My grandpa walks too slowly to catch the bus.
我爺爺走得太慢,追不上公車。
分析:too 之後接副詞 slowly;to V 表示「做不到」的結果。
The tea is too hot for me to drink.
這茶對我來說太燙,喝不下。
分析:喝茶的人是我(不是主詞 the tea),所以用 for me 標明。

規則③④:…enough to 與 enough + 名詞

Lily is old enough to go to school.
Lily 夠大了,可以上學。
分析:enough 放在形容詞 old 後面;to V 表示「做得到」的結果。
Ben runs fast enough to win the race.
Ben 跑得夠快,能贏得比賽。
分析:enough 也可以放在副詞 fast 後面。
We have enough money to buy the tickets.
我們有足夠的錢買票。
分析:enough 修飾名詞 money 時放在名詞前面。

規則⑤⑥:so...that 與 such...that

I was so sleepy that I couldn't keep my eyes open.
我睏到眼睛都睜不開。
分析:so 接形容詞 sleepy;that 子句有自己的主詞與動詞,表示結果。
Ken studies so hard that he always gets good grades.
Ken 用功到總是拿到好成績。
分析:so 也可以接副詞 hard。
It is such a good idea that everyone agrees.
這主意好到大家都同意。
分析:such 接「a + 形容詞 + 單數名詞」;idea 是單數可數名詞,要加 a。
They are such friendly people that everyone likes them.
他們是這麼友善的人,大家都喜歡他們。
分析:people 是複數名詞,such 後面不加 a/an。
There were so many people that we couldn't move.
人多到我們動不了。
分析:many 表數量,前面用 so 不用 such——這是 so/such 判斷的重要例外。

6正確 vs. 錯誤比較

❌ He is enough old to drive. enough 修飾形容詞時要放在形容詞後面,不是前面。
⭕ He is old enough to drive. old enough=「夠大」;to drive 帶出「做得到」的結果。
❌ The box is too heavy to carry it. 主詞 the box 就是 carry 的受詞,to V 後面再接 it 就重複了。
⭕ The box is too heavy to carry. to carry 不加受詞,被搬的就是主詞本身。
❌ She was such tired that she fell asleep. tired 是形容詞,such 之後要接名詞,不能接形容詞。
⭕ She was so tired that she fell asleep. so 之後接形容詞 tired,再接 that 子句。
❌ It was so interesting book that I read it twice. so 不能接「形容詞+名詞」;名詞片語前面要用 such。
⭕ It was such an interesting book that I read it twice. such 接 an interesting book;interesting 母音開頭用 an。
❌ There were such many people in the park. many 表數量時,前面用 so 不用 such。
⭕ There were so many people in the park. so many+複數名詞是固定組合。
❌ I was so nervous that I can't say a word. 主句 was 是過去,that 子句的動詞也要過去(時態呼應)。
⭕ I was so nervous that I couldn't say a word. can't 的過去式是 couldn't,與 was 呼應。
❌ The tea is too hot for me to drink it. 主詞 the tea 已經是 drink 的受詞,再加 it 就重複了。
⭕ The tea is too hot for me to drink. for me 標明喝茶的人;to drink 不再加受詞。
❌ She is too young that she can't drive. too 之後不接 that 子句;接 that 的是 so/such。
⭕ She is too young to drive. / She is so young that she can't drive. 兩種寫法意思相同:too...to 用 to V;so...that 用 that 子句。

7易混淆觀念

① so vs. such(後面接什麼?)

關鍵字後面接例句
so形容詞/副詞She is so kind that everyone likes her.
such(a/an+)名詞片語She is such a kind girl that everyone likes her.
so(例外)many/much/few/little+名詞There was so much rain that the game stopped.

判斷關鍵:先看空格後面是形容詞/副詞還是名詞;若名詞前有數量詞 many/much/few/little,改用 so。

② too...to vs. so...that...can't(等義互換)

句型結構例句
too...totoo+形/副+to VHe is too short to play basketball.
so...that...can'tso+形/副+that+S+can't+VHe is so short that he can't play basketball.

兩句意思相同。改寫時 that 子句要補出主詞,並用 can't 表達「做不到」;too...to 的 to V 則不再接受詞。

③ …enough to vs. so...that...can(等義互換)

句型結構例句
…enough to形/副+enough+to VShe is tall enough to reach the shelf(架子).
so...that...canso+形/副+that+S+can+VShe is so tall that she can reach the shelf.

反向改寫也常用:not+形容詞+enough to = too+反義形容詞+to(not old enough to = too young to)。

④ so...that(結果)vs. so that(目的)vs. , so(所以)

用法意義例句
so...that如此……以至於(結果)It was so cold that we stayed home.
so that以便;為了(目的)We left early so that we could catch the train.
, so所以(因果連接詞,第 35 課)It was cold, so we stayed home.

看語意判斷:so 和 that 之間有形容詞/副詞 → 結果句;so that 連在一起、後面接「想達成的事」→ 目的;so 前面有逗號、連接兩個子句 → 因果。

8判斷技巧:結果句型五步走

  1. 看空格後面接什麼:是 to V?that 子句?還是名詞?——這決定句型家族。
  2. 接 to V:語意是「做不到」→ too+形/副+to V;語意是「做得到」→ 形/副+enough+to V。
  3. 接 that 子句:看 that 前面——形容詞/副詞 → so;名詞片語 → such(單數可數名詞記得加 a/an)。
  4. 接名詞:名詞前有 many/much/few/little 表數量 → 用 so;其他 → 用 such。
  5. 最後總檢查:enough 位置對嗎?too 的 to V 有沒有重複受詞?that 子句的時態有沒有和主句呼應?
🎯 會考實戰心法:這一課最常考的三個陷阱——① enough 的位置(old enough/enough money);② so 與 such 的選擇(接形容詞用 so、接名詞用 such、數量詞前用 so);③ too...to 的 to V 不重複受詞。看到題目先判斷空格後面接什麼,再套家族,就不會被干擾選項牽著走。

🔑 一句話記憶口訣:太而不能 too…to,夠而能 …enough to;so 接形容詞/副詞,such 接名詞;so many/much/few/little 表數量,前面仍用 so;that 帶出結果子句,子句時態要呼應。
