英语构词法中在词根前面加前缀或在词根后面加后缀，从而构成一个与原单词意义相近或截然相反的新词的方法叫作派生法。
除少数英语前缀外，前缀一般改变单词的意义，不改变词性；英语后缀一般改变词类，而不引起词义的变化。
⒈ 表示否定意义的前缀常用的有dis-, il-, im-, in-, ir-, mis-, non-, un-等，在单词的前面加这类前缀常构成与该词意义相反的新词。
如：agree同意→disagree不同意
fair公平的→unfair不公平的
possible可能的→impossible不可能的
understand理解→misunderstand误解
⒉ 表示其他意义的前缀常用的有a-(多构成表语形容词), anti- (反对；抵抗), auto- (自动), co- (共同), en- (使), inter- (互相), re- (再；又), sub- (下面的；次；小), tele- (强调距离)等。
如：co-worker 同事，帮手
enlarge 使变大
cooperate 合作
rewrite 重写
subway 地铁
给单词加后缀也是英语构词的一种重要方法。后缀通常会改变单词的词性，构成意义相近的其他词性；少数后缀还会改变词义，变为与原来词义相反的新词。
⒈ 构成名词的后缀常用的有-ence，-(e)r/ -or (从事某事的人),-ese (某地人)，-ess (雌性)，-ian (精通……的人)，-ist (专业人员)，-ment (性质；状态)，-ness (性质；状态)，-tion(动作；过程)等。
如：differ不同于→difference区别
write写→writer作家
China中国→Chinese中国人
act表演→actress女演员
music音乐→musician音乐家
⒉ 构成动词的后缀常用的有-(e)n (多用于形容词之后)，-fy (使……化)，-ize (使……成为)。
如：wide→widen加宽
beauty→beautify美化
pure→purify提纯
real→realize意识到
organ→organize组织
sharp→sharpen使变锋利
⒊ 构成形容词的后缀常用的有-al，-able (有能力的)，-(a)n(某国人的)，-en (多用于表示材料的名词后)，-ern (方向的)，-ese(某国人的)，-ful，-(ic)al，-ish，-ive，-less (表示否定)，-like (像……的)，-ly，-ous，-some，-y (表示天气)等。
如：nature自然→natural自然的
reason道理→reasonable有道理的
America美国→American美国的
China中国→Chinese中国人的
gold金子→golden金的
east东→eastern东方的
child孩子→childish孩子气的
snow雪→snowy有雪的
⒋ 构成副词的常用后缀有-ly (主要用于形容词之后表示方式或程度)，-ward(s) (主要用于表示方位的词之后表示方向)。
如：angry生气的→angrily生气地
to到→towards朝……，向……
east东方→eastward向东
⒌ 构成数词的后缀有-teen (十几)，-ty (几十)，-th (构成序数词)。
如：six六→sixteen十六→sixteenth第十六
four四→forty四十→fortieth第四十
英语构词法中把一种词性用作另一种词性而词形不变的方法叫作转化法，有的名词可以作动词，有的形容词可以作副词或动词。
⒈ 意思没有变化
如：I think we'd better finish the talk now.我想我们的谈话最好现在结束。
⒉ 意思有一定变化
如：He is a man of strong build.他是一个体格健壮的汉子。
⒊ 构成短语
如：Let's have a look first. 我们先看一下吧。
⒈ 表示物体的
如：Have you booked the ticket?你订好票了吗?
⒉ 表示身体部位的
如：Hand in your papers please.请把你们的试卷交上来。
⒊ 表示一类人的
如：She nursed her husband back to health.她看护丈夫，使他恢复了健康。
⒋ 抽象名词
如：We breakfasted together.我们在一起吃了早餐。
少数形容词可以转化为动词。
如：We will try our best to better our living conditions.我们要尽力改善我们的生活状况。
有少数副词可以转化为动词。
如：Murder will out.恶事终必将败露。
⒈ 表示颜色的形容词常可转化为名词
如：The girl in black appears very beautiful.那个穿黑衣服的女孩子看上去非常漂亮。
⒉ 一些形容词如old, young, poor, rich, wounded, injured等与the连用，表示一类人，作主语时，谓语用复数。
如：We don't belong to the rich, but we dong't belong to the poor either. 我们不是有钱人，但我们也不是穷人。
将单词缩写，词义和词性保持不变的英语构词法称为截短法，主要有截头、去尾、截头去尾等形式。
⒈ 截头
如：telephone→phone
airplane→plane
⒉ 去尾
如：mathematics→maths
examination→exam
kilogram→kilo
laboratory→lab
taxicab→taxi
⒊ 截头去尾
如：influenza→flu
refrigerator→fridge
prescription→script
英语构词还可以将两个词混合或各取一部分紧缩而成一个新词，前半部分表属性，后半部分表主体。这样的英语构词法就是混合法。
如：news broadcast→newscast新闻广播
television broadcast→telecast电视播送
smoke and fog→smog烟雾
photo and graphy→photography摄影，摄影术
helicopter airport→heliport直升飞机场
用单词首尾字母组成一个新词的英语构词法叫做首尾字母缩略法。这种形式的英语构词生成的新词，读音主要有两种形式，即各字母分别读音；作为一个单词读音。
如：Testing of English as a Foreign Language→TOEFL托福
Teach English as a Foreign Language→TEFL
Teach English as a Second Language→TESL
Graduate Record Examination→GRE美国研究生入学考试
陈述句用来叙述一个事实，句末标点用句号。有的陈述句表示肯定的意思，在说话、写文章中，对陈述语气的要求是多方面的，只会简单肯定和否定，不能满足表情达意的需要。因此，陈述句又分为肯定的陈述句和否定的陈述句，简称为肯定句(The Affirmative Sentence)和否定句(The Negative Sentence)。
① 主语+连系动词+表语
② 主语+谓语(不及物动词)
③ 主语+谓语(及物动词)+宾语
④ 主语+谓语(及物动词)+间接宾语+直接宾语
⑤ 主语+谓语(及物动词)+宾语+宾语补足语
⒈ 肯定句：
在说话、写文章中，表示肯定的句子。
⒉ 否定句：
在说话、写文章中，表示否定的句子。
⑴ 一般否定句
即含有“不、没有、完全不是，完全不”等否定意思的词的句子。
⑵ 双重否定句
含有两个否定词的句子，例如：含有“没有.....不......”“,非.....不可......”等词语的句子，双重否定句表示肯定。
陈述句又分为肯定的陈述句和否定的陈述句，简称为肯定句和否定句。含否定词的句子称为否定句（legative Sentence），不含否定词的句子就称为肯定句。
如：Mr.Walker is an Englishman.(华克先生是英国人。一肯定句）
He is not an American.(他不是美国人。一否定句）
否定陈述句的表达方式基本上有下面的三种。
⒈ 全否定：用not,no,never，neither，none,nothing等否定。表示“完全不是，完全不”的意思。
如：He is not a worker.
Nothing is wrong with me.
⒉ 半否定句：在句子里用否定词hardly,scarcely,little，few, seldomrarely等。
如：I hardly see anything in the room.=I can see little in the room
注意：“all/both/every/each/+谓语”表示概念为“有的是，有的不是”
如：All of them are not students.=Some of them are students,some are not.
⒊ 宾语从句的否定形式：用在think,believe,suppose 引导的宾语从句里则否定主句。
如：I don't think he'll come.=He will not come in fact,I think.
肯定句：基本结构为主+谓语/主语+系动词+表语，但是在某些情况下主语和谓语可以倒装：
⒈ 如果虚拟条件句的谓语动词含有were，had或should，可以把if省略掉，而将这三个词放于条件句主语前，构成倒装。
如：Should you be fired,your health care and other benefits will not be immediately cut off.
⒉ 表示方位的副词或介词短语位于句首时，句子要全部倒装。副词有out,in,up，down,
away，off，here,there,now等；大部分介词短语位于句首，都有此种用法；这时句子的谓语动词往往是be，lie，come，walk,go,stand,lie等词。当表示地点的介词短语放句首时，注意：谓语多为be，lie，sit，stand，come,walk等不及物动词。
如：In the dark streets lie many lakes, some large enough to hold several English towns.
⒊ 对含有否定意义，半否定意义的副词或介词短语等放在句首时。这一类常见的副词有：hardly,scarcely,never,not,not only,not until,seldom,little,few,no longer, at no time,by no means,nowhere,in no case等。
如：Never before has the city been in greater need of modern public transport than it is today.
高考对疑问句的考查主要是对反义疑问句的考查。
反义疑问句也叫附加疑问句，指的是在陈述句后面附加一个简短的一般疑问句，用于对陈述句所说的事实或观点提出疑问或表示证实。
陈述部分与附加部分的动词时态和动词性质应保持一致，但是肯定和否定形式却彼此相反，即陈述部分为肯定式时，疑问句部分用否定式；陈述部分为否定式时，附加部分用肯定式。
反意疑问句由两部分构成：前一部分用陈述句形式，后一部分是一个附加在前一部分上的简短问句。陈述部分用肯定形式时，附加问句部分用否定形式，反之亦然。附加问句部分的动词形式及主语由陈述句决定，而且主语必须是代词。
⒈ 陈述部分的主语是名词时，附加问句的主语用相应的人称代词。
如：Your parents had a long talk with you last night,didn't they?
⒉ 陈述部分主语是表示人的不定代词时，反意疑问句的主语侧重全部用they，侧重个体用he。
如：No one was there that day,was he/were they?
⒊ 陈述部分主语是表示物的不定代词时，反意疑问句的主语用it。
如：Everything that he says is true,isn't it?
⒋ 陈述部分的主语是one时，反意疑问句的主语在正式的场合用one，在非正式场合用you。
如：One should be honest,shouldn't one/you?
⒌ 陈述部分主语是指示代词时，反意疑问句的主语要用it或they。
如：This is your car,isn't it?
Those are grapes,aren't they?
⒍ 陈述部分是there be 结构时，反意疑问句仍用there。
如：There was a hospital here,wasn't there?
⒎ 陈述部分有表示推测的情态动词must时，反意疑问句的动词与must后的动词一致。
如：They must be sleeping then,weren't they?
注意：must后接完成式，若表示对过去情况的推测，附加问句中动词用didn't；若表示对已完成情况的推测，用haven't或hasn't。
⒏ 陈述部分含有否定词时，反意疑问句用肯定式。
如：He is never late for school,is he?
They seldom clean the roomdo they?
注意：常见的否定词有no,never,nothing,nowhere,rarely,hardly,seldom,few,little等；若陈述部分有带否定意义词缀的派生词，如dislike，useless，unfair等，后面的附加问句仍用否定式。
⒐ 陈述部分是祈使句时，反意疑问句用will you或won't you。
如：Look at the blackboard,will/won't you?
Don't make any noise,will you?
注意：以Let's开头的祈使句，反意疑问句用shall we；以Let us/me开头的祈使句，反意疑问句用will you；陈述部分是否定的祈使句，反意疑问句用will you或can you都可以。
⒑ 陈述部分是并列句时，反意疑问句与邻近的分句一致。
如：She works hard and she is the best one in her factory,isn't she?
⒒ 陈述部分是复合句时，反意疑问句与主句一致。
如：When the teacher speaks in class,we have to keep quiet,don't we?
⒓ 陈述部分是否定转移句式时，反意疑问句与从句一致，且用肯定形式。
如：I don't think he will come,will he?
注意：在回答反意疑问句时，不管其陈述句部分是肯定的还是否定的，如果事实是肯定的，回答用”yes+肯定的简略句”；如果事实是否定的，回答用”no+否定的简略句”，形式要一致。陈述部分是否定形式时，答语中的yes译成”不”，no译成”是”。
如：—They haven't been told the truth,have they?
—Yes,they have./No,they haven't.
用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句。祈使句的作用是要求、请求或命令、劝告、建议别人做或不做一件事。祈使句的句末一般用感叹号，但是有些祈使句的语气较弱，可以用句号结尾。
祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时。
如：Go andwash your hands.
Be kind to our sister.
Watch your steps.
No parking
表示禁止的句式有：不准、不要、别.
⒈ 肯定结构:
① Do 型(即:动词原形(+宾语)+其它成分)。
如：Please have a seat here.
有的祈使句在意思明确的情况下，动词可省略。
如：This way, please. = Go this way, please. 。
② Be 型(即:Be + 表语(名词或形容词)+其它成分)。
如：Be a good boy! 要做一个好孩子！
③ Let 型(即:Let+宾语+动词原形+其它成分)。
如：Let me help you. 让我来帮你。
⒉ 否定结构:
① Do 型和 Be 型的否定式都是在句首加 don't 构成。
如：Don't forget me!
Don't be late for school!
② Let 型的否定式有两种:“Don't + let + 宾语 + 动词原形 + 其它成分”和“Let + 宾语 + not + 动词原形 + 其它成分”。
如：Do't let him go. / Let him not go. 别让他走。
③ 有些可用 no 开头，用来表示禁止性的祈使句。
如:No smoking!
No fishing!
祈使句是用来向别人提出命令,建议或请求的句式.常见的祈使句有以下五种:
⒈ Let's 开头的祈使句
如: Let's say it in English.
⒉ 动词原形开头的祈使句
如：Listen to the teacher.
⒊ Shall I 开头的祈使句
如：Shall I carry the parcel for you ?
⒋ Will you 开头的祈使句
如：Will you come here early ?
⒌ 以 Please 开头的祈使句
如: Please take a message for him.
⒍ 带呼语的祈使句
如：Mary, come down here ! (对 mary 讲话，而不带呼语的且以动词原形开头的祈使句则对第二人称讲话)
⒎ 不让对方做某事, 英语用 " Don't "
如：Don't speak loud . 不要大声讲话。
Don't write in that way . 不要那样写。
⒏ "let"带头的祈使句是个常见的动词句型，它的主要用法有下列三种：
① 表示“建议”。 这个句型里的"let"后头紧跟着一个第一人称的代词宾语。
如：Let me try.
Let's do it.
Let me go and look for it.这个句型语气委婉，比直接的祈使句客气。
比较：Don't disturb him. 是直接命令，语气强烈
Let's not disturb him.
② 表示“警告”、“蔑视”、“威胁”等。 这种祈使句里的宾语也是第三人称为主。除了口气凶悍之外，有时还语带讽刺.
如：Let him try and he will expose（暴露） his inability（无力） to work on his own.
Let the invaders（侵略者）come and our armed forces will wipe（擦拭）them out in no time.
③ 用"let"的祈使句时，必须注意下列几点
⑴ "let" 的否定句有二。如果宾语是第三人称用"Don't let....."
如：Don't let this type of things happen again.
如果宾语是第一人称，则用 "Let......not"
如：It's raining now. Let's not go out until after the rain.
⑵ "Let"只适用于现在时态，可以有被动语态。
如：Let the recalcitrant criminals be sent to prison.
Let all the dedicated capable staff be promoted.
⑶ "Let"后头除了是不带"to"的不定式动词之外，还可以是某些适当的副词，如 out, in, down, alone 等。
如：Let the puppy out.
Open the windows and let the fresh air in.
The room is too sunny. Let the blinds down.
Let me alone, please.
⑷ 用"Let's"时，把谈话者的对象包括在内；用"Let us"时，并不包括对方。
如：Let's try it, shall we?
Let us do it by ourselves, will you?
从以上两个例句里的"will you"，不难知道前者包括听话人，后者并没有。
⒈ 祈使句=You must…（陈述句）
如：Come here .过来。 =You must come here . 你必须过来。
Don't do that again. = You mustn't do that again 你一定不可以再那样做了。
⒉ Please +祈使句=Will you (please)…?（陈述句）
如：Please help me .请帮帮我。 =Will you (please) help me? 你愿意帮我的忙吗？
Come here on time ,please .请准时到这儿。 =Will you (please) come here on time ? 请你准时到好吗？
⒊ 含有第一、第三人称主语的祈使句
如：Let's say good-bye here. 我们在此道别吧。
Don't let him do that again. 别让他再那么做了。
祈使句有时相当一个“if”引导的条件状语从句。
祈使句：Use your head and you'll find a way.
条件句：If you use your head，you'll find a way.
注意回答 Let's～的反意疑问句句型时，肯定时用 Yes，let's.否定时用 NO，let's not.
⒈ Let's 表示说话人向对提出建议，简短问句的主语用 we 表示，问句用 shall we 或 shan't we
如: Let's have a cup of tea ,shall we (shan't we) ?
⒉ Let me 或 Let us 表示听话人提出请求,问句用 will you 或 won't you.
如：Let me have a rest , will you (won't you ) ?
⒊ 其它的祈使句后可以加一个简短问句,使语气变得客气一些
如：Have a rest , will you?
Stand up , will (won't) you?
一般说来，感叹句是由what或how开头的，它有两个类型，六种句式。掌握了它的搭配，即掌握了感叹句的重点。
此时，what 为形容词，用作定语，修饰它后面的名词或名词词组（即感叹部分是名词性短语）。
⒈ What +a/an 形容词+可数名词单数+主语+谓语！
如：What a fine day it is!多么好的天气啊！（辅音音素前用a）
What an old building that is!那是一栋多么破旧的楼房啊（元音音素前用an）
⒉ What+形容词+可数名词复数形式+主语+谓语！
如：What good teachers they are!他们是多么好的老师啊！
What beautiful flowers these are!这些是多么美丽的花啊！
⒊ What+形容词+不可数名词+主语+谓语！
如：What thick ice we are having here!我们这儿的冰多厚啊！
What round bread it is!这是一块多么圆的面包啊！
此时，how是副词，用作状语，修饰后面的形容词、副词或动词。
⒈ How+形容词+主语+谓语！（即谓语动词是连系动词）
如：How hot it is today!今天天气多热啊！
How beautiful the flowers are!这些花多么美丽啊！
⒉ How+副词+主语+谓语！
如：How hard he works!他工作多么努力啊！
How well she sings!她歌唱得多好啊！
⒊ How +主语+谓语！（即谓语动词是行为动词）
如：How she dances!她跳舞跳得多好啊！
注意：what和how引起的感叹句，在口语中常可以省略主语、谓语或其它句子成分。
如：How cold (it is)!
What a good girl What delicious fish!
判断是否使用冠词、使用什么样的冠词
如果名词不可数，摒弃a，an不留情：名词的复数形式和不可数名词之前不使用冠词，以元音音素开头的词语之前用an，以辅音音素开头的词语之前用a。
如：What beautiful sunshine it is today! （sunshine不可数名词）
What a useful book this is useful!（以辅音音素开头）
What an old house that is old!（以元音音素开头）
有时陈述句、疑问句（句中常有so或much）以及祈使句也可直接转化为感叹句，不需要改变词的位置，只要改变原来的音调（即变为降调）。
如：He's such a nice boy!多好的孩子！
How can you be so clever!你怎么这么聪明！
Don't go with us!刷和我们一起去！
Have you ever seen such a thing?你曾见过这种事情吗?
主语是一个句子所叙述的主体，一般位于句首。但在there be结构、疑问句（当主语不疑问词时）和倒装句中，主语位于谓语、助动词或情态动词前面。主语可由名词、代词、数词、不定式、动名词、名词化的形容词和主语从句等表示。

句式结构：主语+系动词+表语
常见的系动词有：be(是）,get（变得）,become（成为）,turn(变得）,look（看起来）,feel(感到）,smell(闻起来）,taste(尝起来）,sound(听起来）,seem(似乎)

英语构词法中在词根前面加前缀或在词根后面加后缀，从而构成一个与原单词意义相近或截然相反的新词的方法叫作派生法。
除少数英语前缀外，前缀一般改变单词的意义，不改变词性；英语后缀一般改变词类，而不引起词义的变化。
⒈ 表示否定意义的前缀常用的有dis-, il-, im-, in-, ir-, mis-, non-, un-等，在单词的前面加这类前缀常构成与该词意义相反的新词。
如：agree同意→disagree不同意
fair公平的→unfair不公平的
possible可能的→impossible不可能的
understand理解→misunderstand误解
⒉ 表示其他意义的前缀常用的有a-(多构成表语形容词), anti- (反对；抵抗), auto- (自动), co- (共同), en- (使), inter- (互相), re- (再；又), sub- (下面的；次；小), tele- (强调距离)等。
如：co-worker 同事，帮手
enlarge 使变大
cooperate 合作
rewrite 重写
subway 地铁
给单词加后缀也是英语构词的一种重要方法。后缀通常会改变单词的词性，构成意义相近的其他词性；少数后缀还会改变词义，变为与原来词义相反的新词。
⒈ 构成名词的后缀常用的有-ence，-(e)r/ -or (从事某事的人),-ese (某地人)，-ess (雌性)，-ian (精通……的人)，-ist (专业人员)，-ment (性质；状态)，-ness (性质；状态)，-tion(动作；过程)等。
如：differ不同于→difference区别
write写→writer作家
China中国→Chinese中国人
act表演→actress女演员
music音乐→musician音乐家
⒉ 构成动词的后缀常用的有-(e)n (多用于形容词之后)，-fy (使……化)，-ize (使……成为)。
如：wide→widen加宽
beauty→beautify美化
pure→purify提纯
real→realize意识到
organ→organize组织
sharp→sharpen使变锋利
⒊ 构成形容词的后缀常用的有-al，-able (有能力的)，-(a)n(某国人的)，-en (多用于表示材料的名词后)，-ern (方向的)，-ese(某国人的)，-ful，-(ic)al，-ish，-ive，-less (表示否定)，-like (像……的)，-ly，-ous，-some，-y (表示天气)等。
如：nature自然→natural自然的
reason道理→reasonable有道理的
America美国→American美国的
China中国→Chinese中国人的
gold金子→golden金的
east东→eastern东方的
child孩子→childish孩子气的
snow雪→snowy有雪的
⒋ 构成副词的常用后缀有-ly (主要用于形容词之后表示方式或程度)，-ward(s) (主要用于表示方位的词之后表示方向)。
如：angry生气的→angrily生气地
to到→towards朝……，向……
east东方→eastward向东
⒌ 构成数词的后缀有-teen (十几)，-ty (几十)，-th (构成序数词)。
如：six六→sixteen十六→sixteenth第十六
four四→forty四十→fortieth第四十
英语构词法中把一种词性用作另一种词性而词形不变的方法叫作转化法，有的名词可以作动词，有的形容词可以作副词或动词。
⒈ 意思没有变化
如：I think we'd better finish the talk now.我想我们的谈话最好现在结束。
⒉ 意思有一定变化
如：He is a man of strong build.他是一个体格健壮的汉子。
⒊ 构成短语
如：Let's have a look first. 我们先看一下吧。
⒈ 表示物体的
如：Have you booked the ticket?你订好票了吗?
⒉ 表示身体部位的
如：Hand in your papers please.请把你们的试卷交上来。
⒊ 表示一类人的
如：She nursed her husband back to health.她看护丈夫，使他恢复了健康。
⒋ 抽象名词
如：We breakfasted together.我们在一起吃了早餐。
少数形容词可以转化为动词。
如：We will try our best to better our living conditions.我们要尽力改善我们的生活状况。
有少数副词可以转化为动词。
如：Murder will out.恶事终必将败露。
⒈ 表示颜色的形容词常可转化为名词
如：The girl in black appears very beautiful.那个穿黑衣服的女孩子看上去非常漂亮。
⒉ 一些形容词如old, young, poor, rich, wounded, injured等与the连用，表示一类人，作主语时，谓语用复数。
如：We don't belong to the rich, but we dong't belong to the poor either. 我们不是有钱人，但我们也不是穷人。
将单词缩写，词义和词性保持不变的英语构词法称为截短法，主要有截头、去尾、截头去尾等形式。
⒈ 截头
如：telephone→phone
airplane→plane
⒉ 去尾
如：mathematics→maths
examination→exam
kilogram→kilo
laboratory→lab
taxicab→taxi
⒊ 截头去尾
如：influenza→flu
refrigerator→fridge
prescription→script
英语构词还可以将两个词混合或各取一部分紧缩而成一个新词，前半部分表属性，后半部分表主体。这样的英语构词法就是混合法。
如：news broadcast→newscast新闻广播
television broadcast→telecast电视播送
smoke and fog→smog烟雾
photo and graphy→photography摄影，摄影术
helicopter airport→heliport直升飞机场
用单词首尾字母组成一个新词的英语构词法叫做首尾字母缩略法。这种形式的英语构词生成的新词，读音主要有两种形式，即各字母分别读音；作为一个单词读音。
如：Testing of English as a Foreign Language→TOEFL托福
Teach English as a Foreign Language→TEFL
Teach English as a Second Language→TESL
Graduate Record Examination→GRE美国研究生入学考试
陈述句用来叙述一个事实，句末标点用句号。有的陈述句表示肯定的意思，在说话、写文章中，对陈述语气的要求是多方面的，只会简单肯定和否定，不能满足表情达意的需要。因此，陈述句又分为肯定的陈述句和否定的陈述句，简称为肯定句(The Affirmative Sentence)和否定句(The Negative Sentence)。
① 主语+连系动词+表语
② 主语+谓语(不及物动词)
③ 主语+谓语(及物动词)+宾语
④ 主语+谓语(及物动词)+间接宾语+直接宾语
⑤ 主语+谓语(及物动词)+宾语+宾语补足语
⒈ 肯定句：
在说话、写文章中，表示肯定的句子。
⒉ 否定句：
在说话、写文章中，表示否定的句子。
⑴ 一般否定句
即含有“不、没有、完全不是，完全不”等否定意思的词的句子。
⑵ 双重否定句
含有两个否定词的句子，例如：含有“没有.....不......”“,非.....不可......”等词语的句子，双重否定句表示肯定。
陈述句又分为肯定的陈述句和否定的陈述句，简称为肯定句和否定句。含否定词的句子称为否定句（legative Sentence），不含否定词的句子就称为肯定句。
如：Mr.Walker is an Englishman.(华克先生是英国人。一肯定句）
He is not an American.(他不是美国人。一否定句）
否定陈述句的表达方式基本上有下面的三种。
⒈ 全否定：用not,no,never，neither，none,nothing等否定。表示“完全不是，完全不”的意思。
如：He is not a worker.
Nothing is wrong with me.
⒉ 半否定句：在句子里用否定词hardly,scarcely,little，few, seldomrarely等。
如：I hardly see anything in the room.=I can see little in the room
注意：“all/both/every/each/+谓语”表示概念为“有的是，有的不是”
如：All of them are not students.=Some of them are students,some are not.
⒊ 宾语从句的否定形式：用在think,believe,suppose 引导的宾语从句里则否定主句。
如：I don't think he'll come.=He will not come in fact,I think.
肯定句：基本结构为主+谓语/主语+系动词+表语，但是在某些情况下主语和谓语可以倒装：
⒈ 如果虚拟条件句的谓语动词含有were，had或should，可以把if省略掉，而将这三个词放于条件句主语前，构成倒装。
如：Should you be fired,your health care and other benefits will not be immediately cut off.
⒉ 表示方位的副词或介词短语位于句首时，句子要全部倒装。副词有out,in,up，down,
away，off，here,there,now等；大部分介词短语位于句首，都有此种用法；这时句子的谓语动词往往是be，lie，come，walk,go,stand,lie等词。当表示地点的介词短语放句首时，注意：谓语多为be，lie，sit，stand，come,walk等不及物动词。
如：In the dark streets lie many lakes, some large enough to hold several English towns.
⒊ 对含有否定意义，半否定意义的副词或介词短语等放在句首时。这一类常见的副词有：hardly,scarcely,never,not,not only,not until,seldom,little,few,no longer, at no time,by no means,nowhere,in no case等。
如：Never before has the city been in greater need of modern public transport than it is today.
高考对疑问句的考查主要是对反义疑问句的考查。
反义疑问句也叫附加疑问句，指的是在陈述句后面附加一个简短的一般疑问句，用于对陈述句所说的事实或观点提出疑问或表示证实。
陈述部分与附加部分的动词时态和动词性质应保持一致，但是肯定和否定形式却彼此相反，即陈述部分为肯定式时，疑问句部分用否定式；陈述部分为否定式时，附加部分用肯定式。
反意疑问句由两部分构成：前一部分用陈述句形式，后一部分是一个附加在前一部分上的简短问句。陈述部分用肯定形式时，附加问句部分用否定形式，反之亦然。附加问句部分的动词形式及主语由陈述句决定，而且主语必须是代词。
⒈ 陈述部分的主语是名词时，附加问句的主语用相应的人称代词。
如：Your parents had a long talk with you last night,didn't they?
⒉ 陈述部分主语是表示人的不定代词时，反意疑问句的主语侧重全部用they，侧重个体用he。
如：No one was there that day,was he/were they?
⒊ 陈述部分主语是表示物的不定代词时，反意疑问句的主语用it。
如：Everything that he says is true,isn't it?
⒋ 陈述部分的主语是one时，反意疑问句的主语在正式的场合用one，在非正式场合用you。
如：One should be honest,shouldn't one/you?
⒌ 陈述部分主语是指示代词时，反意疑问句的主语要用it或they。
如：This is your car,isn't it?
Those are grapes,aren't they?
⒍ 陈述部分是there be 结构时，反意疑问句仍用there。
如：There was a hospital here,wasn't there?
⒎ 陈述部分有表示推测的情态动词must时，反意疑问句的动词与must后的动词一致。
如：They must be sleeping then,weren't they?
注意：must后接完成式，若表示对过去情况的推测，附加问句中动词用didn't；若表示对已完成情况的推测，用haven't或hasn't。
⒏ 陈述部分含有否定词时，反意疑问句用肯定式。
如：He is never late for school,is he?
They seldom clean the roomdo they?
注意：常见的否定词有no,never,nothing,nowhere,rarely,hardly,seldom,few,little等；若陈述部分有带否定意义词缀的派生词，如dislike，useless，unfair等，后面的附加问句仍用否定式。
⒐ 陈述部分是祈使句时，反意疑问句用will you或won't you。
如：Look at the blackboard,will/won't you?

用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句。祈使句的作用是要求、请求或命令、劝告、建议别人做或不做一件事。祈使句的句末一般用感叹号，但是有些祈使句的语气较弱，可以用句号结尾。
祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时。
如：Go andwash your hands.
Be kind to our sister.
Watch your steps.
No parking
表示禁止的句式有：不准、不要、别.
⒈ 肯定结构:
① Do 型(即:动词原形(+宾语)+其它成分)。
如：Please have a seat here.
有的祈使句在意思明确的情况下，动词可省略。
如：This way, please. = Go this way, please. 。
② Be 型(即:Be + 表语(名词或形容词)+其它成分)。
如：Be a good boy! 要做一个好孩子！
③ Let 型(即:Let+宾语+动词原形+其它成分)。
如：Let me help you. 让我来帮你。
⒉ 否定结构:
① Do 型和 Be 型的否定式都是在句首加 don't 构成。
如：Don't forget me!
Don't be late for school!
② Let 型的否定式有两种:“Don't + let + 宾语 + 动词原形 + 其它成分”和“Let + 宾语 + not + 动词原形 + 其它成分”。
如：Do't let him go. / Let him not go. 别让他走。
③ 有些可用 no 开头，用来表示禁止性的祈使句。
如:No smoking!
No fishing!
祈使句是用来向别人提出命令,建议或请求的句式.常见的祈使句有以下五种:
⒈ Let's 开头的祈使句
如: Let's say it in English.
⒉ 动词原形开头的祈使句
如：Listen to the teacher.
⒊ Shall I 开头的祈使句
如：Shall I carry the parcel for you ?
⒋ Will you 开头的祈使句
如：Will you come here early ?
⒌ 以 Please 开头的祈使句
如: Please take a message for him.
⒍ 带呼语的祈使句
如：Mary, come down here ! (对 mary 讲话，而不带呼语的且以动词原形开头的祈使句则对第二人称讲话)
⒎ 不让对方做某事, 英语用 " Don't "
如：Don't speak loud . 不要大声讲话。
Don't write in that way . 不要那样写。
⒏ "let"带头的祈使句是个常见的动词句型，它的主要用法有下列三种：
① 表示“建议”。 这个句型里的"let"后头紧跟着一个第一人称的代词宾语。
如：Let me try.
Let's do it.
Let me go and look for it.这个句型语气委婉，比直接的祈使句客气。
比较：Don't disturb him. 是直接命令，语气强烈
Let's not disturb him.
② 表示“警告”、“蔑视”、“威胁”等。 这种祈使句里的宾语也是第三人称为主。除了口气凶悍之外，有时还语带讽刺.
如：Let him try and he will expose（暴露） his inability（无力） to work on his own.
Let the invaders（侵略者）come and our armed forces will wipe（擦拭）them out in no time.
③ 用"let"的祈使句时，必须注意下列几点
⑴ "let" 的否定句有二。如果宾语是第三人称用"Don't let....."
如：Don't let this type of things happen again.
如果宾语是第一人称，则用 "Let......not"
如：It's raining now. Let's not go out until after the rain.
⑵ "Let"只适用于现在时态，可以有被动语态。
如：Let the recalcitrant criminals be sent to prison.
Let all the dedicated capable staff be promoted.
⑶ "Let"后头除了是不带"to"的不定式动词之外，还可以是某些适当的副词，如 out, in, down, alone 等。
如：Let the puppy out.
Open the windows and let the fresh air in.
The room is too sunny. Let the blinds down.
Let me alone, please.
⑷ 用"Let's"时，把谈话者的对象包括在内；用"Let us"时，并不包括对方。
如：Let's try it, shall we?
Let us do it by ourselves, will you?
从以上两个例句里的"will you"，不难知道前者包括听话人，后者并没有。
⒈ 祈使句=You must…（陈述句）
如：Come here .过来。 =You must come here . 你必须过来。
Don't do that again. = You mustn't do that again 你一定不可以再那样做了。
⒉ Please +祈使句=Will you (please)…?（陈述句）
如：Please help me .请帮帮我。 =Will you (please) help me? 你愿意帮我的忙吗？
Come here on time ,please .请准时到这儿。 =Will you (please) come here on time ? 请你准时到好吗？
⒊ 含有第一、第三人称主语的祈使句
如：Let's say good-bye here. 我们在此道别吧。
Don't let him do that again. 别让他再那么做了。
祈使句有时相当一个“if”引导的条件状语从句。
祈使句：Use your head and you'll find a way.
条件句：If you use your head，you'll find a way.
注意回答 Let's～的反意疑问句句型时，肯定时用 Yes，let's.否定时用 NO，let's not.
⒈ Let's 表示说话人向对提出建议，简短问句的主语用 we 表示，问句用 shall we 或 shan't we
如: Let's have a cup of tea ,shall we (shan't we) ?
⒉ Let me 或 Let us 表示听话人提出请求,问句用 will you 或 won't you.
如：Let me have a rest , will you (won't you ) ?
⒊ 其它的祈使句后可以加一个简短问句,使语气变得客气一些
如：Have a rest , will you?
Stand up , will (won't) you?
一般说来，感叹句是由what或how开头的，它有两个类型，六种句式。掌握了它的搭配，即掌握了感叹句的重点。
此时，what 为形容词，用作定语，修饰它后面的名词或名词词组（即感叹部分是名词性短语）。
⒈ What +a/an 形容词+可数名词单数+主语+谓语！
如：What a fine day it is!多么好的天气啊！（辅音音素前用a）
What an old building that is!那是一栋多么破旧的楼房啊（元音音素前用an）
⒉ What+形容词+可数名词复数形式+主语+谓语！
如：What good teachers they are!他们是多么好的老师啊！
What beautiful flowers these are!这些是多么美丽的花啊！
⒊ What+形容词+不可数名词+主语+谓语！
如：What thick ice we are having here!我们这儿的冰多厚啊！
What round bread it is!这是一块多么圆的面包啊！
此时，how是副词，用作状语，修饰后面的形容词、副词或动词。
⒈ How+形容词+主语+谓语！（即谓语动词是连系动词）
如：How hot it is today!今天天气多热啊！
How beautiful the flowers are!这些花多么美丽啊！
⒉ How+副词+主语+谓语！
如：How hard he works!他工作多么努力啊！
How well she sings!她歌唱得多好啊！
⒊ How +主语+谓语！（即谓语动词是行为动词）
如：How she dances!她跳舞跳得多好啊！
注意：what和how引起的感叹句，在口语中常可以省略主语、谓语或其它句子成分。
如：How cold (it is)!
What a good girl What delicious fish!
判断是否使用冠词、使用什么样的冠词
如果名词不可数，摒弃a，an不留情：名词的复数形式和不可数名词之前不使用冠词，以元音音素开头的词语之前用an，以辅音音素开头的词语之前用a。
如：What beautiful sunshine it is today! （sunshine不可数名词）
What a useful book this is useful!（以辅音音素开头）
What an old house that is old!（以元音音素开头）
有时陈述句、疑问句（句中常有so或much）以及祈使句也可直接转化为感叹句，不需要改变词的位置，只要改变原来的音调（即变为降调）。
如：He's such a nice boy!多好的孩子！
How can you be so clever!你怎么这么聪明！
Don't go with us!刷和我们一起去！
Have you ever seen such a thing?你曾见过这种事情吗?
