1. 词性（词类）

词性（词类）Parts of Speech

英语的十大词类：动词、名词、冠词、代词、形容词、数词、副词、介词、叹词、连词

1.1 动词 verbs

1.1.1 充当谓语动词

谓语动词的“三大本领”：

1. 动作时间

动作的发生可能在过去、现在或者将来。

• 现在
• 过去
• 将来
• 过去将来（从过去某个时间点打算将来）

2. 动作状态

动作可能处在已经完成或者正在进行的状态。

• 一般（未说明时）
• 完成
• 进行
• 完成进行（不但完成而且继续）

动作时间和动作状态，两者合在一起称为**“时态”**

四种时间和四种状态可以随意排列组合，理论上就会有16种时态。

3. 动作假设，情感等

3.1 动作的“语气”

3.1.1 虚拟语气

• 用来表示意愿，和事实相反的假设等
• If I were a rabbit … （I 后的 were[不是was] 暗示了我并不是一只兔子）

3.1.2 陈述语气

• I ate a carrot and…

3.1.3 祈使语气

• Eat this carrot and…

1.1.2 充当非谓语动词

1. 非谓语动词

动词除了充当句子的谓语动词以外的其他部分合称为“非谓语动词”，做主语、宾语、表语、补语、定语、状语。

• 非谓语动词几乎可以取代所有的从句，从而简化句子。
• 但是非谓语动词丧失了时态，语气，语态这些本领。
• 动词需要通过变形才能出现在句中（不能直接充当非谓语动词）。

1.1 动词不定式

动词不定式：to+动词原形，和谓语动词原形一样。

如：

• Rabbits eat carrots. （谓语动词原形）
• To eat or not to eat? 动词不定式

1.1.1 动词不定式的语法功能

1. 动词不定式作主语：

   • It is easy to be wise after the event.

   • It is easy to ignore the effect of our acts upon their disposition.

   • It is preferable for journalists to rely on their notions of significance and make their judgments.

2. 动词不定式作宾语：

   • He promised not to tell anyone about it.
   • I think it is hard to answer the question in one go.

3. 动词不定式作状语：

   • This will be particularly true since the energy pinch will make it difficult to continue agriculture in the high-energy American fashion that makes it possible to combine a few farmers with high yields.
   • Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty.

4. 动词不定式作定语：

   • An important property of a scientific theory is its ability to stimulate further research and further thinking about a particular topic.

1.2 动名词

动名词，动词+ing，和谓语动词的进行状态一样。

如：

• Eating carrots is healthy. 动名词

1.2.1 动名词的语法功能

1. 动名词作主语：
   • Speaking a language does not necessarily mean that someone understands social and cultural patterns.
   • Getting enough vitamins is essential to life.
   • Using a language is not an easy task.
2. 动名词作宾语：
   • He would not tolerate having his lectures interrupted.
   • I am looking forward to hearing from you.
3. 动名词作状语：
   • In thinking about the evolution of memory together with all its possible aspects, it is helpful to consider what.
4. 动名词作定语：
   • A rather similar process of differentiation has led to professional geologists coming together within one or two societies, whereas(然而) the amateurs have tended either to remain in local societies or to come together nationally in a different way.

1.3 现在分词和过去分词

现在分词，动词+ing，谓语动词的进行状态一样；过去分词和谓语动词的完成状态一样。

如：

• The rabbit is eating. 谓语动词进行状态

• Eating everything, I survived. 现在分词

• The rabbit has eaten. 谓语动词的完成状态

• This is a half-eaten carrot. 过去分词

1.3.1 分词的语法功能

1. 分词做定语

   • After all(毕竟), what is one(有什么) modern form of expression(表达形式) almost completely dedicated to(致力于) depicting(描绘) happiness?
   • The emphasis(强调) on data gathered first-hand, combined with a cross-cultural perspective(跨文化的角度) brought to(使得,进行,对) the analysis of cultures past and present, makes this study a unique and distinctly(明显地) important social science.
   • Databases used by some companies don’t rely on data collected systematically(系统地) but rather lump(无奈地归并) together information from different research projects.
   • The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber or burned as biofuel(生物燃料) in vehicles that would otherwise run on fossil fuels(化石燃料).

2. 分词做状语

   • Waiting for a bus, a brick fell on my head.
   • Reading the letter, she burst out crying.
   • Mocked by everybody, he had my sympathy.
   • Exhausted by the walk, he continued his journey.
   • The best lawyers made skyscrapers full of money, tempting ever more students to pile into law schools.

3. 独立主格结构

   独立主格结构的实质：分词的逻辑主语和主句主语 不一致。

   1. 名词+分词

      • Time permitting, we are going to Beijing Botanical Garden. (主句 we，从句 time)

   2. 介词+名词+分词

      • A car roared past, with smoke pouring from the exhaust(排气管). （主句 car，从句 smoke）

   3. 副词+分词

      • Generally speaking, he is an honest person. （主句 he，从句反正不是he）

1.1.3 助动词 Auxiliary Verbs

英语的谓语动词本身往往是不能够独立完成刚才说的哪些本领，以及另外一些其他的本领。而且谓语动词独自也无法完成比如否定，可能性，必须性等意思。

想让谓语动词充分发挥，我们必须用到另一类经常和动词一起用的词，帮助完成任务——助动词。

词汇在做助动词时，是没有意思的，只是用来帮助构成某种结构（所以也叫结构助词），比如：时态，被动语态，疑问句，否定句等。

1. 常见助动词

can，might，have，be，must，do… …

但是许多的助动词特别喜欢伪装，它们除了做助动词（没有实义，只是帮忙谓语动词而已），还可以做实义动词，甚至其他词性。

例子：

can => 易拉罐，might => 力量，musty => 发霉的，do => 做某事，have => 拥有，be => 存在，… …

所以千万不要把助动词和它其他的身份弄混淆。

2. 助动词的使用

举例：eat

1.2 名词 nouns

名词，表人和物。

• Papa Rabbit is a rabbit.

⭐Attention：名词一定需要配合冠词使用。

名词的常用语法功能：做主语、宾语、表语、同位语。详见：3.3.2 名词性从句

举例：

• 主语：This drawing leaves us with a deep impression.
• 宾语：The early bird catches the worm.
• 表语：Confidence in yourself is the first step on the road to success.
• 同位语：LiMing, the most brilliant boy in the class, is admired by his classmates.

1.3 冠词 articles

• Papa Rabbit is a rabbit.

冠词，英语中说明人和事务。

• 定冠词：the
• 不定冠词：a、an
• 零冠词：就是没有冠词

1.3.1 不定冠词a, an使用

元音音素前用an，辅音音素前用a，不靠元音字母。

• a rabbit /ə ˈræbɪt/ an apple /ən ˈæp(ə)l/

• a university /ə ˌjuːnɪˈvɜːsəti/ an hour /ən ˈaʊə®/

  元音：

• 单元音：/iː/ /i/ /ɪ/ /uː/ /u/ /ʊ/ /e/ /æ/ /ɒ/(office英式/ɒfis/) /ɑː/(office美式/ˈɑːfɪs/) /ɔ/ /ɔː/ /ɜː/ /ə/ /ʌ/

• 双元音：/eɪ/ /ɔɪ/ /aɪ/ /aʊ/ /əʊ/ /ʊə/ /eə/ /ɪə/

1.3.2 名词与冠词的误区

1. 可数名词前面一般要加冠词；
2. 可数名词+定冠词，表示特指； The dog is a friend.
3. 单数可数名词+不定冠词，表示类指； I like an apple.
4. 复数可数名词也可以表示类指； I like apples. Governments should protect dogs.
5. 不可数名词一般不用定冠词，除非特指； Education is important to a person.(The education 就变成强调、特指的意思了)

1.4 代词 pronouns

代词，替代人和物。

• I am a rabbit.

1.5 形容词 adjectives

形容词，形容人和物。

• I am a smart rabbit.

名词的常用语法功能：做定语、表语、补语、状语。详见：3.3.2的定语从句

举例：

• 表语：She is beautiful.
• 宾补：We find the NETEM difficult.
• 状语：The girl stood there, full of fear(形容词短语).
• 定语：He is a handsome boy.

1.6 数词 numerals

数词，表示数量。

• I ate two carrots.

1.7 副词 adverbs

副词，指在句子中表示行为或状态特征的词，用以修饰动词、形容词、其他副词或全句，表示时间、地点、程度、方式等概念。

• I ate two carrots quickly.

1.7.1 副词分类

副词可分为：时间副词、频率副词、地点副词、方式副词、程度副词、疑问副词、关系副词、连接副词、表顺序、表完成的副词。

副词的常见用法：

1. 时间频率副词

   • 频率副词：主要表示“什么时候”、“经常与否”，形容动作所做的次数或频繁程度。

     除了表达某事发生的频率之外，频率副词与一般副词相似。频率副词放在主动词前面，放在be动词后面。

     The items on sale in the supermarket are often sold out quickly.

   • 时间副词：能够表达出某事发生的时间。它可以表达出一个具体的时间，例如两天、昨天、三个星期前等。虽然时间副词有时引导一个句子，但它常常放在句末。例如：

     We’ll let you know our decision next week.下周我们会通知你我们的决定。

     I flew to Dallas three weeks ago.三个星期前我飞去了达拉斯。

   now， then， often， always， usually， next， after last day， already(已经)， generally(一般地)， frequently（频繁 ）， seldom/hardly（很少的）， ever， never， yet， soon， too， immediately（立即）， finally， shortly（很快）， before， ago， sometimes， yesterday， once， twice， lately， recently， personally， today……yet

2. 地点副词

   表示地点与位置关系的副词，用来说明动作发生的地点。

   例如：Tom will go anywhere with his dog.汤姆去哪都带着他的狗。

   here， there， everywhere， nowhere， anywhere， somewhere， in， out， inside， outside， above， below， up， down， back， forward（向前的）， home， upstairs(楼上的)， downstairs， across， along， round， around， near， off， past， up， away， on.……

3. 方式副词

   方式副词能够表达出某人完成某事的方式，它最常与行为动词搭配使用。

   方式副词可以放在句末，或者直接放在动词后。例如：Jack drives very carefully.杰克开车非常小心。

   carefully， properly(适当地)， anxiously(焦虑地)， suddenly， normally(正常地)， fast， well， calmly(冷静地)， politely(有礼貌地)， proudly(自豪地)， softly， warmly， slowly， badly， hard， bravely……

4. 程度副词

   程度副词通常表示某事完成的程度。它们通常位于句末。例如：They like playing golf a lot.他们很喜欢打高尔夫。

   much，little， very，rather(相当)，so，too，still，quite，perfectly(完美地)，enough， extremely(非常)， entirely(整个)，almost， slightly(细小地)， hardly.……

5. 疑问副词

   how， when， where， why……

6. 关系副词

   when， where， why……

7. 连接副词

   therefore(因此)，moreover(此外)，however，otherwise(另外的)，then，when ，where，how，why……

8. 表顺序的副词

   first， then， next， finally， afterward， primarily……

9. 完成时的副词

   already， ever， just， never， since， yet， recently……

1.7.2 副词常见误区

1. 副词混用成连词

   常见的就是连词副词：therefore(因此)，moreover(此外)，however，otherwise(另外的)，then，when ，where，how，why……他们并不能连接两句。

   • He made good preparation for the postgraduate entrance examination, therefore he was admitted to Peking University.

     上面用therefore连接两句话是错误的，要么分成两句，要么用分号连接两句，要么therefore改成so。

1.8 介词 prepositions

英语前置词/介词（preposition ，adposition的一种，还有后置词postposition），表示名词、代词等与句中其它词的关系，在句中不能单独作句子成分。

介词后面一般有名词、代词或相当于名词的其他词类、短语或从句作其宾语，表示与其他成分的关系。

• I ate two carrots with chopsticks.

1.8.1 介词分类

按构成分

前置词表示它后面的名词或代词（或相当于名词的其他词类、短语或从句）与其他句子成分的关系。前置词通常位于名词或代词之前。

（注意：前置词是一种虚词，不能单独作句子成分，只能用在一个名词、代词或相当于名词的结构之前，可以与后面的词一起构成介词短语。）

1. 简单前置词：

   in， on， with， by， for， at， about， under， of， to等。(to为介词，意为“习惯(做)……”，后接名词，代词或动名词形式)

2. 合成前置词：

   由两个单词组成的介词。into， within， throughout， inside， outside， without等。

3. 重叠前置词：

   from among 从…当中，from behind 从…后面，until after 直至…之后，at about 在大约…，after about 在大约…之后 等。

4. 短语前置词：

   一个或两个简单介词 和 一个或几个其他词类 构成一个短语，作用相当于一个介词，这就叫做短语介词。这类介词的末尾总是一个简单介词。

   如 according to， because of， by means of， in addition to， in front of， in spite of 等。

5. 分词前置词：

   有极少数介词的词尾是“-ing”，形似现在分词（其中也有些可做分词）。常用的有：considering， regarding， respecting， including。

1.8.2 介词常见误区

1. 混淆to 和 to

   • 介词to：

     be key to …是…的关键， contribute to 有助于…， give rise to， lead to， conform to， due to，… …

   • 不定式符号to：

     claim to， endeavour to == try to， demand to，… …

2. 介词混淆成连词

   介词一般后面只能接名词或名词性质的短语，不能加句子（除介词后面加宾语从句外）。

   容易当连词的介词（短语）： despite/in spite of/due to/because of/ …despite 尽管

3. 常用介词需牢记

   时间介词：

   • on：日期，具体的上下午 on July 14th，on a fine morning
   • in：用于表示月、年、四季、早晚
   • at：时刻，固定搭配 at noon， at night

1.9 叹词 interjections

叹词，表示感叹。

• Ah, the carrot is tasty!

1.10 连词 conjunctions

连词，用于连接词和句。

• I ate two carrots and a potato because I was hungry.

1.10.1 连词常见误区

1. 同一句子中，连词不能成对出现；

   常见成对出现的连词错误：because…so…，although…but…，…

   • Although we are into our idols, but we should keep a clear head. （两个连词去一）（be into sb. 喜欢某人）

2. 逗号不能连句，分号可以；

   • They get married, I’m happy. （I 前需要加上and/so）

   • He proposed(求婚) to her, and she was very happy. => He proposed to her; she was…（可用分号连句）

2. 句子成分

句子成分 Clause Elements

注意：句子成分 != 词类

举例：句子成分中最特殊的似乎就是谓语动词这一类，其他成分可能是不同的词类，但是谓语动词显然只可能是动词。

2.1 主语

是谓语讲述的对象，一般由名词、代词、不定代词、从句(主语从句)、动名词(v-ing)等来充当，句子叙述的主体，一般位于句首。

• What you said is right. 主语从句

• That the seas are being overfished has been known for years. 主语从句

2.2 谓语

谓语定义就是，说明主语动作或者状态的词语。或者理解为，说明主语做什么、主语是什么、主语怎么样的词语。

2.2.1 谓语动词的类别

• 不及物动词 intransitive verbs
• 及物动词
  • 单及物动词 monotransitive verbs
  • 双及物动词 ditransitive verbs
  • 复杂及物动词 complex-transitive verbs
• 系动词 linking verbs

1. 不及物动词

可以独立完成的动作，没有承受者的动词。Papa Rabbit sleeps.

如果要加宾语，则要加介词。He disagrees with her points.

2. 单及物动词

有1个动作的承受者。

• Papa Rabbit likes you.

3. 双及物动词

有2个动作承受者。两个承受者分别是直接宾语(direct object)和间接宾语(indirect object)。

• Papa Rabbit teaches you English.

区分直宾和间宾：如果删除后句意依然通顺，则删除的是直宾(English)，反之是间宾(you)。

4. 复杂及物动词

只有1个动作承受者，但这个动词必须要有个补充承受者的信息，句意才能完整。

• Papa Rabbit considers you smart.

5. 系动词/连系动词

非“动作”，其描述的动作与我们狭义上说的“动作不同”，以is为代表的一类词，实际作用就是把这个动词之后的信息（性质、状态）赋予给前面的主语，像这样的赋予主语某种性质状态的“划等号”的动词，叫做“连系动词”or“系动词”（linking verbs）。

• Papa Rabbit is tall. / Papa Rabbit is in the room. / Papa Rabbit looks tall. / Papa Rabbit smells nice.

有哪些系动词:

1. 状态系动词

   用来表示主语状态，只有be（am，is，are）一词，例如：

   • He is a teacher. （is 与 补足语一起说明主语的身份）

2. 持续系动词

   用来表示主语继续或保持一种状况或态度，主要有keep， remain， stay， lie， stand，例如：

   • He always keeps silent at meetings.

3. 表象系动词

   用来表示“看起来像”这一概念，主要有seem， appear， look，例如：

   • He looks tired.

4. 感官系动词

   感官系动词主要有feel， smell， sound， taste， see， watch， look，例如：

   • This kind of cloth feels very soft.

5. 变化系动词

   这些系动词表示主语变成什么样，变化系动词主要有become， grow， turn， fall， get， go， come， run，例如：

   • He became mad after that.

注意：

不及物动词和系动词没有被动语态。

• What happened last night? （happen是不及物，没有 What was happend…）

• It tastes delicious. （taste是系动词，没有 It is tasted …）

2.2.2 简单谓语、复合谓语

1. 简单谓语

一个实义动词或者一个动词短语都可以构成简单的谓语。

• 实义动词，就是表示“有实际意义”的动词，用来区别系动词，助动词，情态动词。

• 动词短语/复合动词：动词和另一个单词或者几个单词构成的词组。

  动词短语虽然由几个词语构成，但实际只表示一个动作。如“look after”表示“照顾”且仅仅是一个动作，所以动词短语就相当于一个动词的作用。

常见的简单动词和动词短语：say、talk、speak、type、eat、drink、play、buy、look at、look after、get up等等，以上任何一个实义动词或动词短语都可以作谓语。

2. 复合谓语

复合谓语：简单谓语+其他词语，共同作谓语的情况。

主要有下面三种形式：

1. 情态动词+实义动词或者动词短语的原形

   • I can speak Cantonese/Mandarin. 我会说广东话/普通话
   • I can look after her 我可以照顾她。

   “can”就是一个情态动词， “can speak ”和 “can look after”都是复合谓语。这里涉及到情态动词的情况。

2. 助动词+实义动词或者动词短语的原形

   • I will buy a new book tomorrow. 我明天要买一本新书。 (一般将来时态)
   • I will get up early tomorrow.我明天要早起。(一般将来时态)

   “will buy”和“will get up”都是复合谓语。

3. 助动词+其他的动词形式（be+ doing 或Have/has+ done）

   • I am working now.我现在正在工作。（现在进行时态）
   • I have learned English for 10 years.我已经学了10年英语了。（现在完成时态）

   “am working”和“have learned”都是复合谓语

2.3 宾语

宾语往往表示动作支配的对象，并且总是处在动词的后头。宾语可由名词、代词、数词、名词化的形容词、动名词、宾语从句等来担任。

• Show me（间接宾语）your tickets（直接宾语）, please. 请让我看看你的票。

宾语一般用在(单)及物动词的后面，表示行为动词所涉及的对象。当然还存在双及物动词句型中的双宾语，直接宾语和间接宾语。以及复杂及物动词句型中的宾语和宾补。

• 名词作宾语
  • Show your passport, please. 请出示护照。
• 代词作宾语
  • She didn’t say anything. 她什么也没说。（此处为不定代词）
  • I consider it(形式宾语) important(宾补) to capture her heart(真正的宾语).
• 数词作宾语
  • How many do you want? — I want two. 你要几个？－ 我要两个。
  • How much milk do you want? — A bottle. 你要多少牛奶？— 一瓶。
• 名词化的形容词作宾语
  • They sent the injured to the hospital.他们把伤员送到医院。
• 不定式或ing形式作宾语
  • I decided to go shopping.我决定去购物。
  • I enjoy working with you. 我和你们一道工作很愉快。
• 从句作宾语
  • Did you write down what he said? 你把他的话写下了没有？
  • He takes it(形式宾语) for granted that women are meant to be loved, not to be understood(宾语从句).

2.4 宾语补语/宾补

宾语补语/宾补 object complement，在**“主语+复杂及物动词+宾语+宾语补语”的句型中使用到，补充的信息叫做“补足语”or“补语”（complement），更确切说是“宾语补语”**（object complement）。

举例：

• It drives her crazy(宾补).
• I saw him playing basketball(宾补) yesterday.

宾语补语和主语补语都是补语，因使用的对象不同，又有了不同的命名区别，对应指定的使用场景。

2.5 主语补语，表语

主语补语，subject complement；表语，predicative。

主系表结构：传统语法把系词后的成分称为表语，现代语法把系词后的成分称为主语补足语。

• He was asked to come.
  • 在传统语法和现代语法中，不定式“to come”都叫做主语补足语。
• He is tall.
  • “tall”在传统语法为表语，在现代语法为主语补足语。

因此传统语法是区分主语补语和表语的，而现代语法将其都成为主语补语。我这里就按照传统语法来学。

主语补语或者表语，是补充主语含义而必须加上的部分（可以是词，或者短语，甚至是从句）。

有**“主语+谓语+主语补语…”，“主系表”**两种句型。

举例：

• He was seen playing basketball(主语补语) yesterday.（含有宾语补足语的句子改为被动语态后，原来的宾语成主语，原来的宾语补足语改称为主语补足语）
• You are my sunshine(表语).

2.6 定语

定语 Attributive，主要用来修饰主语或者宾语。可由以下词性词汇担任：adj./n./to do./doing/done/介宾短语/定语从句(后置定语)。

举例：

• adj.：The little white rabbit ate a large carrot.
• 前置定语，后置定语：I have a lot of homework to do.
• adj.，后置定语(doing)： The young man standing in the front of the classroom is No.1.
• 介宾短语： The computer on the table is mine.
• 定语从句： The singer who was popular all over China disappeared for a long time.
• 定语从句： The songs which are sung by Dao Lang were popular.

2.7 状语

状语一般由副词、介词短语、分词和分词短语、不定式、相当于副词的词或短语来担当。其位置一般放在句首，但也可放在句末或句中。

状语 Adverbial，主要用来修饰谓语动词，形容词，副词或全句的词，说明时间，地点，程度，方式等概念。

• 状语的类别：
  • 时间、地点、频率、程度、原因、目的、结果、条件、让步、方式、方面、伴随。

举例：

• 时间：

  • I get up at five(介词短语).

• 地点：

  • We are having breakfast in the dining room(介词短语).

  注：地点状语除表位置外，还可以表“出发”“去向”“距离”等。如：

  • Are you glad to be going back to school? 返回学校你感到高兴吗?

  • They lived many miles from the town. 他们住的地方离镇子好几英里远。

• 频率：

  • I love you three thousand times.

• 程度：

  • The rabbit ate quickly.

  • To a great extent(在很大程度上), it is not fair.

• 原因：

  • The boy was praised for his bravery(勇气)(介词短语).

• 目的：

  • I talk in order to understand; I teach in order to learn.

  • They went out for a walk.

• 结果：

  • He talked his wife into buying a car.

  • The box is too heavy for me to lift.

  • It rained heavily, causing severe flooding(洪水泛滥) in that country.

  • He went to Africa in 1963, never to come back.

• 条件：

  • If I were a boy even just for a day, I’d roll out of bed(get up faster) in the morning. (if从句引导条件状语/状语从句)

  • United, we stand； divided, we fall. 团结则存，分裂则亡。

  • Weather permitting, we’ll have the match tomorrow.

• 让步：

  • For all his money(虽然他很富有), he’s a very lonely man.
  • With all his efforts, he lost the match.
  • Knowing all this, they made me pay for the damage.

• 方式：

  • We came on the bus.

  • You must pay the bill in cash.

  • I watched the game on television.

  • We see with our eyes and hear with our ears.

  • I heard of the job through a newspaper advertisement.

• 方面：

  • She is very weak in physics.
  • China is very rich in natural resources.
  • This is better in every way than that.
  • The bridge is 2500 meters in length and 150 meters in height.

• 伴随：

  • I slept with the window open.

• She said goodbye with tears in her eyes.

  • He ran up to her breathing heavily.

• He rushed into the room, his face covered with sweat.

2.8 同位语

同位语 Appositive，

主要用来再把主语或宾语说一遍。

• Papa Rabbit, an English teacher, eats carrots.

  Papa Rabbit 和 English teacher 是同一事务的不同解释，具有相同的地位。

3. 造句：英语语法的目的

3.1 简单句

3.1.1 简单句

简单句（Simple Sentence）

长句拆解到不能再拆，并且拆了句意会不完整的“基本句子”。

除去感叹句、省略句、（向整句提问）问句，其他的句子都是在说什么怎么样；而什么、怎么样就是句子成分（Clause Elements）。

什么+怎么样 => 主语Subject+谓语Predicate，主语与谓语是最基本的两种句子成分，几乎所有的英语句子结构都是主语+谓语。

• 主语：一般是人或物，不管抽象还是具体；

• 谓语：都有一个广义的"动作/发生了什么事儿"

  • 动作：不是指狭义的要"动起来"的"动作"，而是广义的动作是指语法中的动词Verbs。

  谓语与谓语动词是有区别的，句子主语后面的余下句子部分就是谓语，谓语动词只是谓语的一部分。

3.1.2 五大基本句子结构

五大基本句子结构 对应了 动作（谓语动词）的五大类别：

• 不及物动词 =》 主语+不及物动词
• 及物动词
  • 单及物动词 =》 主语+单及物动词+宾语
  • 双及物动词 =》 主语+双及物动词+间宾+直宾
  • 复杂及物动词 =》 主语+复杂及物动词+宾语+宾补
• 系动词 =》 主语+系动词+表语

1. 主+谓/vi.

可以独立完成的动作，没有承受者的动词。

• Papa Rabbit sleeps.

2. 主+谓/单vt.+宾

有1个动作的承受者，宾语。

• Papa Rabbit likes you.

3. 主语+谓/双vt.+间宾+直宾

有2个动作承受者，直接宾语和间接宾语。

区分直宾和间宾：

直接宾语表示动作的承受者，一般是物；间接宾语表示动作是受影响的事物或人，一般是人。

还有如果删除后句意依然通顺，则删除的是直宾(English)，反之是间宾(you)。

• Papa Rabbit teaches you English.

4. 主语+谓/复杂vt.+宾+宾补

只有1个动作承受者，且需要**“宾语补语”**补充信息，句意才能完整。

• Papa Rabbit comsiders you smart.

**区分双及物 与 复杂及物：**如果去掉宾补，复杂及物的句子会不完整；而双及物句子去掉直宾，意思仍然完整。

5. 主语+系动词+表语

系动词实际作用就是把这个动词之后的信息（性质、状态）赋予给前面的主语，其后面的补充信息就是“表语”。

• Papa Rabbit is tall. / Papa Rabbit is in the room. / Papa Rabbit looks tall. / Papa Rabbit smells nice.

3.2 复合句/并列句

复合句（Compound Sentence）

复合句就是对句子进行简单地叠加，句子之间通过连接词连接起来，分句间的关系是平等的。

3.2.1 常见连接词

• 顺接：
  • and， both…and…， not only…but also…， not only…but…as well， as well as，
• 转折：
  • but，whereas(但是/却,侧重前后对比)，yet，
• 选择：
  • … or…，either…or…，neither…nor…，
• 因果：
  • because， so，

3.3 复杂句

复杂句（Complex Sentence）

复杂句对句子是进行相互嵌套，句子之间是从属关系。

3.3.1 主句和从句

• 主句 Main Clause
• 从句 Subordinate Clause
  • 从句就是把简单句子修改后，充当另一个句子（不一定是主句，句子可以套多层）的句子成分。

3.3.2 复杂句类型

1. 名词性从句

名词性从句类别：

• 主干类从句：主语从句，宾语从句，表语从句；
• 修饰类从句：同位语从句。

主语从句、宾语从句、表语从句和同位语从句，具有名词的性质，合称为名词性从句。

常用连接词

• that：无实义
• whether/if：表是否
• 特殊疑问词：表状态
  • 一类：
    • when：表时间
    • where：表地点
    • how：表方式（how+从句:如何…），表程度（how+adj./adv.+从句:多么…）
    • why：表原因
  • 二类：
    • what、 who、 whom、 whose

特殊疑问句第二类引导词(连接词)：连接从句为非完整句，引导词在从句中做主语或宾语；其余引导词连接完整的从句。

1.1 主语从句

主语从句位置：句首，句末（含有形式it）。

1.1.1 普通主语从句

• Why he told me the secret is clear now.
• That the plates are moving is now beyond dispute.
• How well the predictions will be validated by later performance depends upon the amount, reliability, and appropriateness of the information. （how表程度）

why, that, how 连接的都是完整句。

普通主语从句变为形式主语：

• That she is into her idol is known to all. [be into sb. 喜欢某人] => It is known to all that she is into her idol.

1.1.2 形式主语it

1.4 同位语从句

1.4.1 何为同位语

同位语：在名词旁对其进行解释。

• Yihan, an English teacher, is giving a class.
• I have just received a letter from my brother, Tim.

注意：

1. 同位语一般由名词（结构）来充当（名词、动词不定式、动名词、同位语从句）；
2. 同位语的功能：解释；
3. 同位语删去后，不影响句子结构的完整性。

1.4.2 同位语从句

• We found out the murderer, Tom(同位语).

  We found out the fact that he was killed.

• The news is true.

  The news that she made is true.

1.4.3 同位语引导词

• 分隔式同位语从句——特殊的同位语从句
  • He got a piece of news from Mary that Bob had gotten rid of single life. [一般同位语是贴着的，这里就分开了]

2. 定语从句

2.1 定语从句的构成

• He loves the girl who is beautiful.

  the girl：先行词，被修饰的名词(结构)，先于定语从句；who：关系词/引导词

2.2 定语从句的类别

从修饰的语义紧密与否的角度可分为：限定性定语从句和非限定性定语从句。

• 限定性定语从句：不能省略，否则不完整，与先行词关系紧密，所以不用逗号；
• 非限定性定语从句：描述、补充作用，与先行词关系不紧密，因此可用逗号分隔。

表象区别：限定性定语从句（设逗号），非限定性定语从句（没逗号）；本质区别：先行词的（具体or广泛）范围是否明确。

举例：

• The man, whose IQ was said to be lower than 85, was elected as the president, which surprised the world.
• Do you remember the teacher who taught us English vocabulary?

2.3 关系词/引导词

定语从句的引导词可分为关系代词和关系副词两种。

a. 关系代词

关系代词：that、which、who、whom、whose、as、than。

• 关系代词在从句中做主语、宾语、表语、定语；同时做宾语时，关系代词可省。

  关系代词可分为 必要成分关系词：who whom which that；非必要成分关系词：whose when where why

  必要成分(主语 宾语 表语)，从句缺少关系代词会句意不完整；非必要成分(定语 状语)，从句缺少不影响句意，仅是修饰作用。

  • The one who was talking to you a minute ago is a professor. （who做主语，先行词one）
  • I walked to the gate that opened towards the lake. （that作主语，先行词gate）
  • As is known to everybody, the moon travels around the earth once every month. （as作主语，指代主句）
  • The reason that she gives is unbelievable. （that做宾语，可省）
  • This is the house which we bought last month. （which做宾语，可省）
  • The man whom I met yesterday is Jim． （whom做宾语，先行词man，可省）
  • This is the pen which he bought yesterday. （which做宾语，先行词pen，可省）
  • He wants a room whose window looks out over the sea. （whose做定语，先行词room）

• 关系代词who，whom，whose的区别

  • who、whom只用于指人；who在定语从句中做主语，whom在定语从句中做宾语。

    who可代替whom作宾语，但介词后面必须用whom。

    • She said she huffed(蔑视) the persons who flattered(讨好) her. （who指人，做主语）

      The man who / whom you met just now is called Jim. （who/whom指人，做宾语，所以who whom皆可）

      She brought with her three friends, none of whom I had ever met before. （whom指人，做宾语，虽做宾语，但有介词所以用whom）

  • whose既可指人，也可指事或物，在定语从句中主要用做定语。

    • This is the woman whose name is known all over the country. （whose指人，作定语，谁的）

b. 关系副词

关系副词：when、where、why、whereby(表方式；凭此,借以)；关系副词不在从句中充当成分。

• The day when we stop learning is the day when we die.
• Literature is the place where the past meets the present to contemplate(考虑,思考) the future.
• Schools have always been in a society where practical is more important than intellectual.
• There is the so-called(所谓的) a big deal, where institutional(机构的) subscribers pay for access to a collection of online journal titles through site-licensing agreements.
• That’s one reason why we have launched(发布) Arc, a new publication dedicated to the near future.
• The definition also excludes(排除) the majority of teachers, despite the fact that teaching has traditionally been the method whereby many intellectuals(知识分子) earn their living.

c. 介词+关系代词 = 关系副词：

介词+which / whom：从句中的介词提前，当涉及修饰对象时。

• 如：on which = when，表示当在某天时

举例：

• High growth rates(高增长率) increased the chances for academic innovation(创新); they also weakened the forms and processes by which teachers and students are admitted into a community of scholars during periods of stability or slow growth. 他们同样削弱了老师和学生在发展稳定和缓慢增长时期被接纳为学术群体的形式和过程。

2.4 as 引导的定语从句

a. as引导限定性定语从句的条件

如所修饰的名词前有such， the same， as出现，后面的从句将有as引导。

• He’ll repeat such questions as are discussed in the book.

• Such a student as works hard will be sure to succeed.

• They made the same mistake as others would have made on such an occasion.

• He tried to make as few mistakes as he could avoid.

• Besides, this is unlikely to produce the needed number of every kind of professional in a country as large as ours and where the economy is spread over so many states and involves so many international corporations.

  两句并列的定语从句用and相连，都是修饰"country"。

b. as引导非限定性定语从句

as引导非限定性定语从句和which相似，往往指代一整句话。不过位置相对比较灵活，可以位于先行词之前、之后或者中间，而which引导的非限定性定语从句只能位于先行词之后。

• As is true of any developed society, in America a complex set of cultural signals, assumptions, and conventions underlines all social relationships.

  与任何发达社会一样，在美国，所有的社会关系都受到一系列复杂的文化信号、假设和习俗的影响。

画图写作作文常用句型：（如上图所示，…）

• As is shown in the pictures, …
• As is seen from the chart, …
• As is vividly portrayed(描绘) in the cartoon above, …

2.5 than引导定语从句

than引导的定语从句有如下用法特点：

1. than可作关系代词引导定语从句，在从句中充当主语或宾语；
2. than前面的主句需有形容词的比较级形式；
3. 比较级所修饰的名词即为先行项。

例句：

• She donated(捐赠) more than could be expected.
• His help is more valuable than was supposed.
• There is more money than is needed.
• The Milky Way(银河) is made of more stars than anybody can count.
• We must not have more furniture in our rooms than is required for convenience.
• They came earlier than was expected.

习题：There ought to be less anxiety over the perceived risk of getting cancer than ______ in the public mind today.
A. exists　B. exist　 C. existing　 D. existed

【答案】A；根据以上分析我们知道，这个句子是than引导的定语从句；上文说过的than的用法特点“比较级所修饰的名词即为先行项”，所以可以判断出定语从句的先行项是名词anxiety；又因为先行项是单数形式，所以谓语动词应为exists这一单三形式，故正确答案为A

P.S. 传统语法认为，该语法现象是than引导的比较状语从句省略了主语或宾语it，如：

• His help is more valuable than（it）was supposed.

2.6 区分同位语与定语的that从句

• 同位语从句：解释

  • 引导词在从句中不做成分，不能省略。

  • The news that she has a crush on him is true.

    “she has a crush on him”，是个完整的句子

• 定语从句：修饰

  • 在从句中做成分，作宾语时that可省略。

  • The news that he told me is true.

3. 状语从句

状语类别：时间⭐、地点、原因⭐、结果⭐、目的、条件⭐、让步⭐、比较、方式。

主从句顺从关系：时间、地点、原因、结果、目的、条件、方式；主从句转折关系：让步；比较状语不一定，可多可少也可以一样。
