“too … to” / “enough to”

Too 表示超過了需要或合適的程度（常常因此做不了某事）；enough 表示達到了需要的程度。它們的位置不同：

要說明誰做這件事，在 to + 動詞 前面加 for + 賓語：too heavy for me to carry。

• The box was too heavy for me to carry.

  這個箱子太重了，我搬不動。

• Is the water warm enough to swim in?

  水夠暖和，可以下去游泳嗎？

💡注意位置：enough 放在形容詞或副詞後面（old enough、fast enough），但放在名詞前面（enough money、enough time）。

1. too：超過合適的程度，所以做不了或不好

• I'm too tired to cook tonight.

  我今晚太累了，不想做飯。

• I got up too late to catch the bus.

  我起得太晚，沒趕上公交車。

2. not … enough：沒達到需要的程度

• My son is only fifteen, so he isn't old enough to drive.

  我兒子才十五歲，所以他還不到開車的年齡。

• He didn't run fast enough to catch the bus.

  他跑得不夠快，沒趕上公交車。

3. enough：達到需要的程度——沒問題

• She's old enough to decide for herself.

  她已經長大了，可以自己做決定。

• Is the room big enough for 30 people?

  這個房間夠 30 個人用嗎？

4. 和名詞連用：enough / too much / too many——enough 也可以單獨使用：I've had enough。

• We don't have enough time to see everything today.

  今天我們沒有足夠的時間把所有東西都看完。

• I drank too much coffee this morning.

  我今天早上喝了太多咖啡。

• There are too many tourists here in summer.

  夏天這裡遊客太多了。

• No more rice for me — I've had enough, thanks.

  我不要米飯了——我已經吃飽了，謝謝。

要加強或減弱 too 的語氣，用 much too / far too 或 a bit / a little too——形容詞前面不用 too much。

• These jeans are much too small for me now.

  這條牛仔褲現在對我來說太小了。

• It's a bit too expensive to eat there every day.

  每天都在那裡吃飯有點太貴了。

💡Too 通常帶有負面意思——超過了好的程度。中文說“太好了”“太漂亮了”是誇獎，但英語不能直接說 too good 來誇獎：要用 so 或 really：This is so good!（You're too kind 這樣的固定說法是例外。）

當句子的主語就是 to + 動詞 的作用物件時（the tea = 你要喝的東西），句末不要再重複它。如果動詞需要介詞（swim in、sit on），介詞要保留。

• The tea is too hot to drink.

  茶太燙了，沒法喝。（不說：to drink it）

• The water was too cold to swim in.

  水太冷了，沒法下去游泳。

如果句子以 It（形式主語）開頭，賓語要保留。too / enough 後面用 to + 動詞——不用 -ing，也不用 for + -ing。

• It's too dangerous to swim in this river.

  在這條河裡游泳太危險了。（不說：too dangerous swimming）

• My daughter is too young to go to school.

  我女兒還太小，不能上學。（不說：for going）

• ✗He is enough old to vote.

  ✓He is old enough to vote.

  enough 放在形容詞後面。

• ✗It was very cold to go swimming.

  ✓It was too cold to go swimming.

  做不了這件事 → 用 too，不用 very。

• ✗The tea is too hot to drink it.

  ✓The tea is too hot to drink.

  不要重複 it——茶就是你要喝的東西。

• ✗It's too much expensive to eat there every day.

  ✓It's too expensive to eat there every day.

  形容詞前面用 too（或 much too），不用 too much。

• ✗This jacket is too small to me to wear.

  ✓This jacket is too small for me to wear.

  表示人 → 用 for + 賓語。

• ✗We don't have enough of money.

  ✓We don't have enough money.

  enough + 名詞；enough of 只用於 the/my/them… 前面。
