高中英语强调句
强调是有效地进行思想交流的重要手段之一。人们在交际过程中，为了使自己的思想能被对方恰当的理解，必须加强语气，突出重要的内容，增加对比效果与感情色彩，这时就会用到强调。强调常见的表现形式如下：
一、强调句型
为了强调句子的某一成分（通常是主语、宾语、或状语），常用强调句型：It is +被强调部分+that… 表示强调的 it 在句子中作主句的主语；被强调部分可以是主语，宾语，表语或状语；强调的主语如果是人，that和who都可用。如：
Last night I saw a film in the Youth Palace.
强调主语：It was I that / who saw a film in the Youth Palace last night.
强调宾语：It was a film that I saw in the Youth Palace last night.
强调地点状语：It was in the Youth Palace that I saw a film last night.
强调时间状语：It was last night that I saw a film in the Youth Palace.
另外，还要注意下面几点：
1）在强调主语时，that 后的谓语动词要与被强调者保持人称和数的一致。如：
It is I who am a teacher.
2）即使被强调的主语是复数，主句中的谓语动词也用单数。如：
It is they who often help me with my lessons.
3）在强调时间、地点、原因或方式状语时，不能用when，where，why或 how ，而要用that 。如：
It was because her mother was ill that she didn't go with us.
It was only when I reread his poems recently that I began to appreciate their beauty.
It was the house that the murder happened.
4）在强调not … until 结构中由 until 短语（或从句）表示的时间状语时，要用固定的强调句型：It is not until ...that... 注意此时原句的not…until要变成not until ，that 从句中的谓语动词要用肯定式。如：
My father didn't come home until 12 o'clock last night.
It was not until 12 o'clock last night that my father came home.
I didn’t realize she was a famous film star until she took off her dark glasses.
It was not until she took off her dark glasses that I realized she was a famous film star.
5）原句的谓语动词如果是现在或将来的各种时态，用It is…that …；如果原句谓语动词是过去各种时态，则用It was… that…
6）在强调一般疑问句中的某一成分时，主句要用一般疑问句的语序。that后面的原句其余部分在移走了被强调部分后词序及词形都不可以改动。如：
Did this happen in Beijing?
Was it in Beijing that this happened?
7）特殊疑问句中只有疑问词可以强调，其强调结构是“疑问词+is it that...? " 如：
Where were you born?
Where was it that you were born?
8）强调句型容易和句型It is/was+名词+that名词从句混淆。如果把构成强调句型结构的词It is … that… 去掉，被强调部分归位后，应该能够形成一个完整 的句子（这也是判断是否是强调句型的方法）。但后者的It is/was…that 是不可去掉的，否则that前的名词就找不到位置，原句也不再成立，如下面这个句子如去掉It is/was…that就不再完整：
It was the rule of the school that the pupils should wear their school uniforms
强调句型还容易跟It is/was+形容词+that名词从句这一句型混淆。如：It is clear that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为”清楚”是主语从句最常见的一种结构。
It is very clear that he’s round and tall like a tree.
That he’s round and tall like a tree is very clear.
9)强调句可以用作宾语从句。如：
He told me that it was because he was late for class that he was punished.
I really can’t remember where it was that I first met the man.
10）强调句型可有如下变体：It is/was变成“情态动词+be”。如：
It may be my bike that he is riding.
It must have been the manager that spoke to you.
11）与疑问词连用构成特殊疑问句和感叹句。如：
Whom was it that Mr. Smith saw in the park yesterday?
Why is it that silver is not widely used as a conductor?
What a beautiful picture it is that you have drawn!
12）被强调的名词或代词可带有一个定语从句。如：
Was it Bill, who plays football well, that helped the blind man cross the road?
It was in the school, where（or：in which） I once studied, that we hold a party.
Was it in the house, which we visited last year, that the murder happened?
二、用助动词do或其变化形式does，did来强调句中谓语动词，用来加强陈述句和祈使句的语气，译作“的确”，“一定”，“确实”。如：
He did send you a letter last week.
We’re pleased that she does intend to come.
Do write to me when you get there．
三、用倒装句来加强语气。如：
Only in this way can we solve this problem．
Never will China be the first to use nuclear weapons.
Proud as these nobles are, they are afraid to see me.
In front of the farmhouse there sat a little boy.
四、用形容词, 副词或者否定词very, never, ever, even, still , single，simply, just ,only, too等来表示强调。如：
At that very monent he heard a cry for help.
I can't even remember the name of that old friend of mine.
Not a single person has been in the office this afternoon．
You are the only person here who can speak Chinese．
This is just what I wanted．
五、用what引导的名词性从句或wh-疑问词+ever构成的复合词引导的状语从句来强调从句中的主语，宾语或状语等。如：
What Mary does every day is to give piano lessons.
Whenever you come to me, you can come right in.
六、反复使用同一个词来加强语气 ，可反复使用词的一般是动词， 副词，形容词和名词。如：
He worked worked until late at night.
They walked for miles and miles．
I'll never, never forget you.
七、 用“at all”，“in every way”，“in no way”，“by all means”，“by no means”，“only too”，“all too”，“but too”，“in heaven”，“in the world”，“in hell”，“on earth”，“under the sun”等来加强疑问或否定语气。如：
Where in the world did you go just now ?
What on earth are you doing?
She's not in the least angry with me.
The clerk is not at all fit for the post.
八、用感叹句来表示强烈的感情，突出说话人的情感。如：
How interesting a story it is！
九、 用反身代词表示强调 。如：
I myself will see her off at the station．
You can do it well yourself．
十、用破折号、黑体字也可以表示强调，加强语气：
It's because of hard work—ten years of hard work．
追问那个Youth Palace 是什么意思？
那个Youth Palace 是什么意思？

追问哦，懂了，谢谢你。

英语句子里的主语。
谓语 宾语各是指的什么
组成句子的各个部分叫句子成分。
英语句子成分有主语，谓语，表语，宾语，宾语补足语，定语，状语等。
顺序一般是主语，谓语，宾语，宾语补足语，而表语，定语，状语的位置要根据情况而定。

求一些动名词作主语的英语句子
如何判断英语句子中的语法成分之主语 主语是英语句子中一个主要语法成分，常出现在句首（但出现在句首的并非总是主语）。
这一讲我们将学习英语句子主语的形式选择、意义选择和主谓一致三个方面。
一、主语的形式选择 主语表示句子描述的是“谁”或“什么”，是谓语的陈述对象，由名词性的成分来充当，说明人物、地方、行为、事件、事实等。
英语中除了名词和代词（47页例1-3）之外，名词性的成分还包括： （一）“定冠词the+形容词”，可起名词作用，表示某一类的人或事物。
The blind often have sharp hearing. The wise are those who know themselves. The Chinese love peace. The good in him outweighs the bad. （二）动词的非谓语形式（不定式或动名词）可起名词作用。
在英语中，当动词不是用作句子谓语，而是用于充当其他语法功能的时候，动词就会以非谓语形式出现，主要有三种：不定式（Infinitive）、分词（Participles）和动名词（Gerund）。
其中，可以充当主语的非谓语形式是不定式和动名词。
1、不定式作主语 （1）当不定式作主语时，如果较短，可直接出现在常规的主语位置，如：To leave or stay is a question hard to answer. To say something is one thing, to do it is another. 但是如果不定式充当的主语较长而谓语较短时，常用“it”作形式主语，而把真正的不定式主语放在谓语的后面。
It'll be a crime to stay anywhere else. It's always a good ides to get a second opinion. It would be wrong not to take this problem into consideration. 有时，不定式的前面可以有一个连接词、连接代词或连接副词（包括whether, what, which, whom, where, when, how）。
不定式的这种结构在句中主要起宾语作用，如： He will tell us how to use the library. 他将告诉我们如何使用图书馆。
但也可以作主语，如 What to buy for dinner is not decided yet. Where/Where/How/Who to prepare the dinner is not decided yet. 2、动名词作主语 （1）动名词与现在分词同形，但主要起名词作用，在句中可充当主语，如课本47页例5: Learning English grammar is by no means easy. Seeing is believing. Reading French is easier than speaking it. 在一些习惯表达中，常用形式主语“it”，而将作主语的动名词短语放在后面，多见于某些形容词或名词之后，其他情况一般不用it作形式主语代替作主语的动名词。
如： It is no use telling him not to worry.It is no good talking about that. It is worthwhile trying again. It is a water of time trying again. 当动名词有自己的逻辑主语时，常可以在前面加上一个名词或代词的所有格，构成动名词的复合结构（这时，名词或代词的所有格做动名词的逻辑主语）。
动名词的复合结构也可以在句中作主语。
例如： Their coming to help was a great encouragement to us. *动词不定式和动名词都可以用作主语。
在意义上相近。
但动名词多用来表示泛指或抽象动作，不定式多用来表示特指或具体动作。
比较： Smoking is not good for health. It is not good for you to smoke so much （三）主语从句 1、句子也可以起名词作用，在句子中充当主语，形成主语从句。
判断主语从句时，可先找到句子的谓语，谓语前面的从句就叫做主语从句。
如 Who murdered Joan/Why Jack murdered Joan/When Jack murdered Joan remains unknown. Why he left wasn't important. That she became an artist may have been due to her father's influence. 2、借助形式主语it，主语从句放在后面。
（1）由that引导的主语从句可以放在主语的位置，这时that不可以省略。
例如：That prices will go up is certain. that主语从句放在句首的情况不是很常见，绝大部分主语从句都借助形式主语it，主语从句放在后面。
如： It is strange that he knows nothing about it. It is a pity that he can't swim. It happened that he wasn't in that day. It is said that there has been an earthquake in India. 在口语中，用it做形式主语时，主语从句的that可以省略。
（2）wh-疑问词引导的主语从句，可以放在句首（第一组），也可以借助形式主语it（第二组）。
第一组：When he'll be back depends much on the weather. How it was done was a mystery. Whether we'll succeed remains to be seen. 第二组：It is uncertain whether the game will be held. It's a puzzle how life began. It doesn't matter much where we live. Is it known where he went？ 注意：疑问词后面的语序应为正常的陈述语序。
二、主语的意义选择 除了形式上的多样性之外，英语句子的语义类型也是多种多样的，包括动作的执行者、动作的承受者、动作得以完成的工具、事件的原因、地点、谈论的话题等等。
Jack murdered Joan with a gun. Joan was murdered by Jack with a gun. A gun killed Joan. Cancer deprives many people of their lives. The hall can seat 50 people for a conference. Learning Chinese Kongfu is by no means easy. 在实际的语言使用中，我们可以根据自己的意图来选择主语的意义类型。
一般来说，主语通常总是某种已知给定的信息，是后面谓语部分的评述对象。
The bees swarmed ...
英语中句子可以做主语吗？
补语的作用对象是主语和宾语，具有鲜明的定语性描写或限制性功能，在句法上是不可或缺的。
补语是起补充说明作用的成份。
最常见的是宾语补足语。
名词、动名词、形容词、副词、不定式、现在分词、过去分词都可以在句子中作宾补。
主语+动词+宾语+补语 我用斜杆分开补语的部分能让你更清楚理解，避免混淆~~1. You make me / sick. 你让我感到恶心2. We believe him / to be guilty. 我们相信他是有罪的.3. We made him / copy the sentence. 我们让他复制这个句子4.
