以下的動詞后面，不定詞的后面都要省掉to。
動詞 例句
let My mother let me watch TV tonight.
make He makes his students respect teachers.
have He had his sons clean their rooms.
see I saw him run away.
hear I heard the birds sing.
watch I watched the kids play.
notice I noticed her cry.
因為在這些動詞的后面，本來應該用不定詞，僅僅是to被省掉了，因此我們在這些動詞的后面仍然要用原式，以下的句子都是錯的：
＊He made his son ran away from home.
＊I saw him walked away..
＊I have never heard him sang any song.
Help這一個動詞非常特別，它后面的不定詞中的to可省略也可不省，以下的句子都是對的：
I helped him wash his car.
I helped him to wash his car.

第十章 如何將動詞改成形容詞
我們中文里，一個字有時是動詞，有時卻又可以用作形容詞，的例子是〝微笑老蕭〞（蕭萬長院長的外號）〝微笑〞應該是動詞，可是在這里，顯然〝微笑〞是形容詞。〝哭泣〞通常是動詞，可是我們也可以說〝哭泣的孩子〞。也難怪我們常見到以下錯誤的英文句子：
＊ a smile face
＊ a run boy
需知smile和cry都是動詞，是不能當作形容詞來用的。
可是，更糟糕的是以下句子：〝住在臺灣的人很有錢〞，我們很多人會說
＊ People live in Taiwan are rich.
以上的話為什么錯呢？因為People是主詞，are是動詞，live in Taiwan形容people，可是live是一個動詞，不能用作形容詞的。怎么辦呢？我們可以將一個動詞用成一個形容詞，我們的做法是利用分詞（participle）和不定詞（infinitive），而分詞有兩種：現在分詞（present participle）和過去分詞（past participle），我們在下一節(jié)，先談現在分詞的用法。
10§1 現在分詞（present participle）作為形容詞
任何一個動詞，都有一個現在分詞（present participle），現在分詞的形式是在動詞后面加上ing，如：
laughing
crying
walking
swimming
running
以下的例子中，現在分詞都是形容詞
a crying baby
a smiling girl
an exciting story
running water
a running boy
a rising star
現在分詞不一定放在名詞的前面，在以下的句子中，現在分詞都在名詞的后面
a person walking in the woods
the young man running very fast
people living in Taiwan
the person driving that red car
the singer singing the national anthem（國歌）
the boys playing in the fields
the young boy swimming in the pool
以下句子中的現在分詞，都被用作形容詞。
We have a crying baby here.
Seeing is believing.（believing是形容詞，seeing是名詞）
Loving is forgiving.
He always wears a smiling face.
Running water is important for mankind.
Look at the rising sun.
The person swimming in that cold river is quite strong.
The young man driving the red car is rich.
Those boys playing basketball are happy.
This movie is exciting.
This news is very upsetting.
This story is troubling.
The young boy swimming in the pool is my brother.
People living in the United States consume more energy than other people.
The person painting the house there is from Mexico.
She has a loving husband.
He is a rising star.
【練習四十四】
將以下的中文句子譯成英文，每句都要用現在分詞
1. 這是一本有趣的故事。
2. 這門課很無聊（boring）。
3. 看那只在唱歌的鳥。
4. 那位微笑的人是我的哥哥。
5. 住在鄉(xiāng)下的人通常很健康。
6. 我不認識那位騎腳車的男孩子。
7. 那位正在吃冰淇淋的小孩子是我的兒子。
8. 那位在問問題的學生非常聰明。
9. 你見過那位打籃球的男孩子嗎？
10.那位垂死（dying）的病人是我的老師。
10§2 過去分詞（past participle）作為形容詞
在完成式中，我們要用過去分詞，過去分詞也可以作為形容詞，以下是一些例子：
a broken window （破碎的窗）
a fallen angel （墮落的天使）
a fallen star （已經不走紅的明星）
a depressed person （一個沮喪的人）
a much appreciated action （為人很欣賞的動作）
究竟過去分詞和現在分詞何不同呢？過去分詞多半有動被和已經完成的意思。好的例子是：開發(fā)中家叫做a developing country，已開發(fā)國家就叫做a developed country。
以下的例子可以解釋過去分詞和現在分詞的不同：
1. (a)這本書很有趣。
This book is interesting.
(b)我對這本書很有興趣。
I am interested in this book.
2. (a)這是一部令人沮喪的電影。
This is a depressing movie.
(b)我看了這部電影以后，感到非常沮喪。
I felt very much depressed after seeing that movie.
3. (a)結果令人失望。
The result is frustrating.
(b)他因這個結果而非常失望。
He was frustrated because of the result.
4. (a)這個消息真令人難過。
This news is really upsetting.
(b)他們都很難過。
They are all upset.
5. (a)約翰的進步令人鼓舞。
John’s progress is encouraging.
(b)我因約翰的進步而感到鼓舞。
I am encouraged by John’s progress.
6. (a)水在燒。
The water is boiling.
(b)這是燒開的水。
This is boiled water.
7.(a)這個消息出人意外。
This news is surprising.
(b)我對這個消息感到意外。
I was surprised by the news.
8. (a)他的談話令人困惑。
His words are confusing.
(b)他是一個充滿困惑的人。
He is a confused person.
記住，以下的句子都是錯的：
＊His statements are confused to me.
＊I am interesting in music.
＊He is an interested person.
＊This is indeed a surprised news.
＊This news is encouraged.
正確的句子應該是：
His statements are confusing.
I am interested in music.
He is an interesting person.
This is indeed a surprising news.
This news is encouraging.
以下是含有過去分詞的句子，每一個過去分詞都用作形容詞：
America is a developed country.
I found that dog killed in a car accident.
The frustrated student needs help.
I want the report completed before midnight.
He is totally depressed.
They are all frustrated.
The car driven by that young man is a Cadillac.
This book, read by almost every one, was written by Charles Dickens.
This is still an unrealized dream.
Are you interested in music?
I am really surprised to meet you.
I was excited by his arrival.
The girl dressed in white is from Japan.
A depressed person needs love from others.
Millions got killed in the Second World War.
He is a troubled child who needs advice.
I have a broken leg.
Broken glass is all over the place.
千萬注意，我們不可以輕易亂用過去分詞，以下的句子都是錯的：
＊He is suffered.
＊This article will be appeared in the next issue of Science.
正確的說法是：
He suffers.
This article will appear in the next issue of Science.

22. This song, (hear) by almost everyone, was written by me.
23. I don't like the song (write) by the Beatles.
24. She is a (care) woman.
10§3 不定詞（Infinitives）作為形容詞和副詞
不定詞可以用作名詞，也可以用作形容詞，以下都是不定詞用作形容詞的例子，要注意的是不定詞不會放在名詞的前面：
You don't have the right to talk so loudly.
He is to blame.
To see is to believe.（To see是名詞，to believe是形容詞）
My job is to teach poor kids to learn.
We all have the duty to serve our country.
He has a talent to sing.
I don't have time to play.
He is a person to be liked by us all.
This is a book to be read by all students.
He has no money to spend.
This is not a good place for kids to grow up in.
This law is to protect innocent citizens.

9. 我的工作是教小孩英文。
10. 我看到你，感到很意外。（surprised to…...）
11. 我們有很多可談的事。
12. 他沒有可以交談的朋友。
第十一章 詞組（Phrases）和子句（Clauses）
請看以下的句子，特別注意劃線的字群：
1. Understanding English is easy.
2. I want you to work hard.
3. Peter, who has been to England, speaks good English.
4. I told him that I was going away.
Understanding English和to work hard有一共同特色，他們都沒有主詞，也沒有動詞，這種字群，叫做詞組（phrase）。
Who has been to England和I was going away中，內部都有主詞和動詞，這種字群，叫子句（clause）。
由于我們已經對詞組很熟悉，我們在這里不再討論，而我們在這一章將多多介紹子句的用法。
11§1 問題型式的名詞子句
假如我們說〝我不知道他住在哪里〞，或者〝他究竟住在哪里仍是個謎〞，我們就可以用這種問題型式的名詞子句，每一個名詞子句都要用who, where, whether, which等來開始。以下是典型的例子：
I don't know where he came from.（我不知道他來自何處。）
Whether or not he is an American is still a secret.（他是否是個美國人仍然是個秘密。）
I will find out where he is living.（我要找出他住在哪里。）
I can not remember whether he smokes or not.（我不記得他是否吸煙。）
Please let me know how old he is.（請讓我知道他多大年紀。）
Kindly tell me what you really need.（請讓我知道你需要什么。）
You have to decide which book you want to buy.（你應該決定買哪一本書。）
Do you know where he is from?（你知道他是從哪里來的？）
Do you know who he is?（你知道他是誰嗎？）
Please ask your brother whether he is coming or not.（請問你的兄弟他會不會來。）
When she is coming remains a puzzle.（她何時來仍然是個謎。）
I don't know what he is interested in.（我不知道他的興趣何在。）
I don't understand what he is talking about.（我不知道他在談什么。）
Do you know whose bicycle this is?（你知道這輛腳踏車是誰的嗎？）
Do you know which country Hawaii belongs to?（你知道夏威夷屬于哪一個國家嗎？）
You should ask your mother where you were born.
（你應該問你的母親你在哪里生的。）
雖然每一個名詞都有問題的意義，我們卻不能在名詞子句中用問句的型式，因為畢竟這個名詞子句僅僅是一個子句而已，它的結尾并不是〝？〞。
因此以下的句子都是錯的：
＊I don't know where did he come from.
＊I will find out how old is he.
＊Kindly tell me what do you need.
＊You have to decide which book do you want to buy.
＊When is he coming remains a puzzle.

10. 你知道發(fā)生了什么事嗎？

6. Do you know who is the president of the United States?
7. May I ask you which kind of coffee do you like?
8. I can not remember how old am I?
9. What is he talking about is unclear to me.
10. Do you know why is he coming?
動詞 例句

make He makes his students respect teachers.
have He had his sons clean their rooms.
see I saw him run away.
hear I heard the birds sing.
watch I watched the kids play.
