如何区分英语四大从句.ppt
首先要清楚的了解句子的成分，即在句子中什么是主语、谓语、宾语、表语、定语、状语等，举个例子：we are Chinese，we是主语，are是表语，Chinese是宾语。这是简单的句子，主语表语宾语都是只有一个词，而所谓的从句就是句子的某个成分由短语或句子构成，这个短语或句子在句子中属于什么成分，它就是什么从句，举个例子：That light travels in straight lines is known to all （众所周知，光沿直线运动）That light travels in straight lines在句子中做主语，所以这个句子是主语从句。（我是这样理解的）
从句有名词性从句、形容词性从句、副词性从句（我就学过这三种）。名词性从句包括主语从句、宾语从句、表语从句、同位语从句。形容词性从句即定语从句。副词性从句即状语从句。个人觉得只要弄清句子成分就可以很好判断出从句类型。
英语语法句子结构讲解
英语语法中，句子类的结构我们需要知道的一些知识。下面是我给大家整理的英语语法句子结构讲解，供大家参阅!
英语语法句子结构讲解：S十V句式
在此句式中，V是不及物动词，又叫自动词(vi.)。例如：
He runs quickly.
他跑得快。
They listened carefully.
他们听得很仔细。
He suffered from cold and hunger.
他挨冻受饿。
China belongs to the third world country.
中国属于第三世界国家。
The gas has given out.
煤气用完了。
My ink has run out.
我的钢笔水用完了。
英语语法句子结构讲解：S十V十O句式
在此句式中，V是及物动词(vt.)，因此有宾语。例如：
I saw a film yesterday.
我昨天看了一部电影。
Have you read the story?
你读过这个故事吗?
They found their home easily.
他们很容易找到他们的家。
They built a house last year.
他们去年建了一所房子。
They‘ve put up a factory in the village.
他们在村里建了一座工厂。
They have taken good care of the children.
这些孩子他们照看得很好。
You should look after your children well.
你应该好好照看你的孩子。
英语语法句子结构讲解：S十V十P句式
在此句式中，V是系动词(link v.)，常见的系动词有：look，seem，appear，sound，feel，taste，smell，grow，get，fall ill/asleep，stand/sit still，become，turn等。例如：
He is older than he looks.
他比看上去要老。
He seen interested in the book.

He stood quite still.
他静静地站看。
He becomes a teacher when he grew up.
他长大后当了教师。

注意：有些动词同时也是及物动词，可构成SVO句式，例如：

他上下打量我。
He reached his hand to feel the elephant.
他伸出手来摸象。
They are tasting the fish.
他们在品尝鱼。
They grow rice in their home town.

Please turn the sentence into English.
请把这个句于泽成英语。
英语语法句子结构讲解：S十V十O十C句式
在此句式中，V是有宾语补足语的及物动词。常带宾语补足语的词有形容词、副词、介词短语、名词、不定式、现在分词、过去分词。
常见的可接宾语补足语的动词很多，哪些动词可接哪几种形式作宾补，须根据动词的惯用法而定，不能统而概论。请看下面的例子。
They made the girl angry.
他们使这个女孩生气了。
They found her happy that day.
他们发现那天她很高兴。
I found him out.
我发现他出去了。

英语语法句子结构讲解：S十V十O1十O2句式
在此句式中，V是带有双宾语的及物动词。常见的须带双宾语的动词有give，ask，bring，offer，send，pay，lend，show，tell，buy，get;rob，warn等。例如：
He gave me a book/a book to me.
他给我一本书。
He brought me a pen/a pen to me.
他带给我一枝钢笔。

他把座位让给我。
注意下边动词改写后介词的变化：

妈妈给我买了一本书。
He got me a chair/a chair for me.
他给我弄了一把椅子。
Please do me a favor/a favor for me.
请帮我一下。
He asked me a question/a question of me.
他问我个问题。
注意，下边动词只有一种说法：

他们抢了老人的钱。
He‘s warned me of the danger.
他警告我注意危险。
The doctor has cured him of his disease.
医生治好了他的病。

英语的句子的结构。
总体而言，英语的句子成分有主语，谓语，宾语，定语，状语，主语补语（常指表语），宾语补语，形容词补语，同位语，独立成分这十类组成，每种成分的常见表现形式最多不超过三类：单词，短语，从句。比方说，以主语为例，您需要再进一步搞清楚哪些单词或短语可以充当该成分，从句作主语有什么注意事项（如作主语的句子是陈述句、一般疑问句、特殊疑问句时各有什么要求及注意须知等等），如此这般将每个成分过上一遍，保证您的语法底子坚如磐石！
主语有两种定义（请务必注意句子成分的定义与句子结构是密不可分的!!!)
1．在“主语+谓语”结构中，主语是陈述/被陈述的对象或说明/被说明的事物。
1）主语+ 系动词+ 表语 ：He is a fanciful writer（他是一位富有想象力的作家。）
2）.主语+ 半系动词+表语：
She looks lovely in white.（她穿白色衣服看上去很漂亮。）
His face went cool again.（他的面孔又变冷漠了。）
she remained serene and in control.( 她依旧泰然自若。)
Our vision appears limited.（看来我们的目光短浅。）
注：请特别注意以上四句的谓语动词，它们在这里代表着四组不同类别的半系动词
3）主语+不及物谓语动词/ 不及物动词短语：
The breeze has died away.( 微风渐渐止住了.)
2．在“主语+谓语+宾语”结构里，主语是动作的发出者。
能够作主语的一般有：名词、代词、数词、动名词、名词化的形容词【即：the+形容词表示每一类的人或物，如：the rich(富人)，the poor（穷人）等），此外还有动词不定式、动名词短语，名词短语，形容词短语，代词短语和从句（即主语从句）】。
谓语同样也是两类定义：
1）在“主语+系动词+表语”结构中，谓语=系动词+表语，在 “主语+不及物谓语动词/不及物动词短语”中，谓语就是该不及物动词或不及物动词短语。
2）在“主语+谓语+宾语”结构中，谓语是主语所发出的动作。此时谓语由动词来担任。(详情参阅链接提示中内容）
宾语总体分为动宾和介词宾语两大类，动词宾语是仅指“主语+谓语+宾语+......”类结构而言，宾语是主语所发出的动作的承受者，介词宾语则是指放在介词后面单词、短语或从句（详情请参看英语语法书）宾语可由名词、代词、数词、名词化的形容词、不定式、动名词、宾语从句等来担任。
定语是用来修饰名词或代词的修饰限定成分，放在被修饰词的前面或后面。（一般称为“修饰、限定名词或者代词的成分”。
定语有两类，位于被修饰词之前的单个词或者合成词称作前置定语；位于被修辞之后的单词、短语或从句称作后置定语。前置定语可以由名词,形容词和起形容词作用的词（如数词、现在分词、过去分词）来担任；后置定语则由形容词、介词短语、现在分词短语、过去分词短语和从句来担任。
前置定语见以下例句：
There is a a baby girl in the cradle. （摇篮里有一个女婴）baby就是名词作前置定语。
I am waiting for your reply. (我在等你答复) your就是形容词性物主代词作前置定语。
He is a business- is –business man.(他是一个公事公办的人) business- is –business 就是合成词作前置定语。
后置定语分为三类，详情见下：
单词：
1）以a开头的形容词： a world anew 一个崭新的世界（其中，anew就是后置定语，用来修饰限定world 。）
2)修饰限定“复合不定代词”的形容词：I have something important to tell you.我有些重要的事情要对你说。（其中，important 就是后置定语用来修饰something.）
短语：
1）He had the ability to push aside all difficulties 他有能力排除一切困难。
（句中，to push aside all difficulties 就是动词不定式作后置定语，修饰ability.)
2)The girl in red is his sister. 穿红衣服的那个女孩是他妹妹。
（句中介词短语in red 就是The girl 的后置定语）
3）I hopped into a taxi standing at the door. 我跳进一辆停在旅馆门口的出租车。
（句中，standing at the door就是现在分词短语作a taxi 的后置定语）
4）He is a man rude but henpecked．他是一个粗暴而惧内的男人。（形容词短语作后置定语）
从句：
1）He lives in the house which is opposite ours. 他住在我们对面的那栋房子里。（句中，从句which is opposite ours就是the house 的后置定语）
2）This is a pretty flower, whose name I don't know. 这是一种很美的花,我不知道它叫什么名字.
（句中，whose name I don't know就是a pretty flower的后置定语）
补语有三大类：
主语补足语：一般多体现为表语形式，表语即是主语补足语的最常见的一类。
宾语补足语（放在宾语后面补充说明宾语的成分）
形容词补足语：放在形容词后面，用来补充说明该形容词的内容，原因等的成分。例如：
I am glad to see you again.(我很高兴再次见到你。）本句中的to see you again就是动词不定式作形容词glad的补语，补充说明高兴的原因，再如：
Mike is confident that he will arrive in time. （迈克相信他会及时到达。 ）句中的confident 就是形容词，其后的 that he will arrive in time就是形容词补语从句。
状语包含的内容很复杂：用以说明地点、时间、原因、目的、结果、条件、方向、程度、让步、方式和伴随、比例、比较等十余种概念的成分称作状语，具体表现形式为“单词、短语、从句”三类，状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语以及从句来担当。其位置一般放在句末，但也可放在句首或句中。 （详情请参看英语语法书“状语章节”，此处不多赘叙。
以上是句子中重要成分的介绍，余者还需参看语法书）
至于您末尾的一问，可以100%的肯定答复您：You are my best friend不是主谓宾结构，而是“主语+系动词+表语”结构，You是主语，are是系动词，my best friend是表语，其中，my 和best都是friend的前置定语， are my best friend是“系动词+表语”充当合成谓语，所以整个句子又可以说是属于一种“主语+谓语”结构
