不定詞 (to＋原行動詞)概述
一、基本觀念
(1) 不定詞是所有的動狀詞裏，功用最多的，可以當名詞、形容詞、以及副詞。
二、動狀詞包括：現在分詞、過去分詞、動名詞、原形動詞和不定詞
動狀詞的否定：永遠在動狀詞最前面加 not
(1) 現在分詞：只能當形容詞使用，表主動和進行；
例子：1. The definition of a word is a sentence or a phrase giving the meanings
of the word. = The definition of a word is a sentence or a phrase
which gives the meaning s of the word. (表主動)
2. It’s dangerous to drink boiling water. = It’s dangerous to drink watch
that is boiling. (表進行)
3. Do you see the cat playing with the ball? (表進行)
【感官動詞後面可以接原行動詞、現在分詞和過去分詞：接原形
表動作發生過，接現在分詞強調動作正在進行，接過去分詞表被
動。】
(2) 過去分詞：也只能當形容詞使用，表被動和完成；
例子：1. Broken cups are useless.= The cups which are broken are useless.
(表被動)
2. In autumn, the high mountains are full of fallen leaves.
= In autumn, the high mountains are full of leaves which have fallen.
(表完成)
3. I have heard the same song sung many times. (表被動)
(3) 動名詞：則是為具有動詞特性的名詞，通常當作名詞使用，但也可轉變為
形容詞，用來修飾名詞的功用，跟現在分詞修飾名詞的性質和狀態不一
樣，這兩者之間要有所區分。
例子：1. Driving too fast is dangerous. (動名詞當主詞)
2. She practices playing the piano every day. (動名詞當動詞的受詞)
3. I have been used to living in this hustle and bustle city.
(動名詞當介係詞的受詞)
4. The fastest way is taking a taxi. (動名詞當主詞補語)
5. Good eating habits are necessary to everyone.
(動名詞 eating 轉變成形容詞，用來修飾名詞 habit 的功用。)
6. Spelling lessons are sometimes borings.
(動名詞 spelling 轉變成形容詞，用來修飾名詞 lessons 的功用。
因為 spelling 是形容詞，不能當主詞，真正的主詞應該是 lessons。)
7. Spelling long words is difficult for me.
(Spelling 是純粹動名詞，用來當此句的主詞，long words 則當
spelling 的受詞；單一動名詞當主詞時，永遠都是第三人稱單數。)
1
8. I can’t catch up with that running boy. (running 是現在分詞，修飾
名詞 boy 的狀態。)
9. I saw him stealing your car. (stealing 是現在分詞，修飾名詞 him 的
狀態。
(4) 原形動詞：則是要放在某些特定的動詞之後當受詞或當受詞補語。
例子：1. He helps set the table. (set 是原形動詞，當 helps 的受詞。)
2. Please help me carry the heavy box.
(carry 是原形動詞，當受詞補語，補充說明受詞 me。)
3. Mother made me do the dishes.
(do 是原形動詞，當受詞補語，補充說明受詞 me。)
4. Have someone fix my car quickly, please.
(fix 是原形動詞，當受詞補語，補充說明受詞 someone。)
5. Don’t let him watch too much TV.
(watch 是原形動詞，當受詞補語，補充說明受詞 him。)
(5) 不定詞：可以當名詞、形容詞、以及副詞。

三、不定詞的功用：可以當名詞、形容詞和副詞
(1)當名詞：可以當主詞、受詞、主詞補語、和受詞補語
(a) 當主詞：(常可用虛主詞 it 代替)
例：1. To finish the job is the most important thing for me.
= It is the most important thing for me to finish the job.
2. To solve the problem is not easy.
= It is not easy to solve the problem.
3. To finish homework on time is every student’s duty.
= It is every student’s duty to finish homework on time.
虛受詞和虛主詞之區分：
1. 虛主詞：I don’t think that to be there on time is possible.
= I don’t think that it is possible to be there on time.
(這個句子有兩個子句，主要子句 I don’t think 和從属子句 it is possible to be
there on time，在從属子句裏，it 是主詞，當虛主詞。)
(虛主詞可以用不定詞來代換)
虛受詞：I don’t think it possible to be there on time.
(這個句子，只有一個子句，it 當 think 的受詞，是虛受詞，真正的受詞是
後面的不定詞 to be there on time)。
≠ I don’t think to be there on time possible.
(虛受詞不可以用不定詞來代換)
2
2. 虛主詞：I think (that) it is wrong to tell a lie.(兩個子句)
(it 是從属子句的主詞，wrong 是主詞補語)
= I think that to tell a lie is wrong.
虛受詞：I think it wrong to tell a lie.(一個子句)
(it 當 think 的受詞，wrong 是受詞補語)
≠ I think to tell a lie wrong.

四、簡單式的不定詞 (to＋v.)和完成式的不定詞 (to＋have＋pp.)之區分：
(1) 簡單式的不定詞：不定詞的動作所發生的時間和動時的時間一致，如是現式
則都同為現在式，如是過去式，則都同為過去式：
例子：
1. I am sorry to be late. = I am sorry that I am late.
2. I was sorry to be late. = I was sorry that I was late..
3. He seems to be happy. = It seems that he is happy.
4. He seemed to be happy. = It seemed that he was happy.
(2) 完成式的不定詞 (to＋have＋pp)：不定詞的時間一定比動詞早，動詞若是現
在式，則不定詞的時間一定是過去式或是現在完成式；動詞如為過去式，則不
定詞的時間一定是過去完成式。
1. He seems to have been rich. = It seems that he was (has been) rich.
2. He seemed to have been rich. = It seemed that he had been rich.
3. He seems to have known you before.
= It seems that he knew (has known) you before.

五、代不定詞 to：不定詞如果接 want, wish, hope, hate, like, try, have(必須), need,
used (過去的習慣), be able, be going 等動詞時，可以將不定詞的原形動詞省略，
只保留 to，以避免重複。
例子：
1. I don’t buy the coat because I don’t want to (buy it).
2. Have you had your lunch? No, but I am going to (have it).
3. Would you like to have dinner with us? Yes, I’d like to (have dinner with you).

6. I don’t know if I can make it, but I’ll try to (make it).
六、在虛主詞代替不定詞的句型中，對於某某人來說，原本都用 for＋人；但在
表讚賞以及責備的句型中，都是用 of＋人：
例子：
一般用法
1. It is easy for me to answer this question.
2. It is necessary for him to get up earlier.
3. It is important for us to be there on time.
