中国人轻松学英语常用语法(11)
第十一章 词组（Phrases）和子句（Clauses）
请看以下的句子，特别注意划线的字群：
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，他们都没有主词，也没有动词，这种字群，叫做词组（phrase）。
Who has been to England和I was going away中，内部都有主词和动词，这种字群，叫子句（clause）。
由于我们已经对词组很熟悉，我们在这里不再讨论，而我们在这一章将多多介绍子句的用法。
11§1 问题型式的名词子句
假如我们说〝我不知道他住在哪里〞，或者〝他究竟住在哪里仍是个谜〞，我们就可以用这种问题型式的名词子句，每一个名词子句都要用who, where, whether, which等来开始。以下是典型的例子：
I don’t know where he came from.（我不知道他来自何处。）
Whether or not he is an American is still a secret.（他是否是个美国人仍然是个秘密。）
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.（我不记得他是否吸烟。）
Please let me know how old he is.（请让我知道他多大年纪。）
Kindly tell me what you really need.（请让我知道你需要什么。）
You have to decide which book you want to buy.（你应该决定买哪一本书。）
Do you know where he is from?（你知道他是从哪里来的？）
Do you know who he is?（你知道他是谁吗？）
Please ask your brother whether he is coming or not.（请问你的兄弟他会不会来。）
When she is coming remains a puzzle.（她何时来仍然是个谜。）
I don’t know what he is interested in.（我不知道他的兴趣何在。）
I don’t understand what he is talking about.（我不知道他在谈什么。）
Do you know whose bicycle this is?（你知道这辆脚踏车是谁的吗？）
Do you know which country Hawaii belongs to?（你知道夏威夷属于哪一个国家吗？）
You should ask your mother where you were born.
（你应该问你的母亲你在哪里生的。）
虽然每一个名词都有问题的意义，我们却不能在名词子句中用问句的型式，因为毕竟这个名词子句仅仅是一个子句而已，它的结尾并不是〝？〞。
因此以下的句子都是错的：
＊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.

选择适当的代名词，如whether, which, what, who, how, when, why等填入下面句子的空格（有时会有多种正确的填法）：
1. I don’t know book you bought.
2. Do you know he is from?
3. Please ask him he drinks tea or not.
4. he is thinking about is well known to all of us.
5. Let me guess old you are.
6. May I ask you are so sad?
7. I don’t know he is.
8. Do you know house this is?
9. This is not I want.
10. I don’t care you want to say.
11§2 以that开始的名词子句
现在我们先试着翻译以下的句子：
地球是圆的是众所周知的事。
一种直接了当的翻译是：
＊The earth is round is known to everyone.
遗憾的是，以上的句子是不对，我们必须加一个that到名词子句里去，以下的翻译是正确的：
That the earth is round is known to everyone.
我们再来翻译一个中文句子：
我要求他一定要用功念书。
直接了当的翻译可能像下面的：
＊I demand he must work hard.
这是错的，我们应该加一个that在这个名词子句的前面。以下的翻译才是正确的：
I demand that he must work hard.
虽然我们常看到这种that被省略的情形，我们仍希望大家知道，为保险起见，最好不要省掉that。以下是一些例子：
That the sun rises from the west is wrong.（太阳从西方升起是错的）
That a lot of Jews were killed during the Second World War is now a historical fact.
（大批犹太人在第二次大战中被杀是历史上的事实）
I didn’t know that he is such a diligent student.（我不知道他是如此勤快的学生）
I demand that you go away.（我要求你离开）
I suggest that you go swimming every morning.（我建议你每天早上游泳）
That we should all respect our parents should be taught to our kids.
（我们该教孩子们尊敬父母）
I don’t think that he is a good athlete.（我不认为他是一个好运动员）
Do you think that she is a good actress?（你认为她是一个好的演员吗？）
That he can speak good English helps him.（他能说很好的文，这点对他很有帮助）
I propose that we get married.（我建议我们结婚）
Let us always remember that there are a lot of poor people in the world.
（我们永远记住世界上有很多穷人）
Never forget that we should always love one another.（不要忘记我们应该互相友爱）
I am surprised to find out that he is a Catholic.（我很惊讶地发现他是个天主教徒）
That we lost the game made all of us frustrated.（我们输了，这件事令我们大感沮丧）
