它用在名词的前面 帮助指明名词的含义 英 语中的冠词有三种 一种是定冠词 the Definite Article 另一种是不定冠词 the Indefinite Article 还有一种是零冠词 Zero Article 一 不定冠词的用法 a an 1 表示 一个 意为 one 指某人或某物 A Mr Ling is waiting for you 2 代表一类人或物 A knife is a tool for cutting with Mr Smith is an engineer 词组 a little a few a lot a type of a great many many a in a hurry in a minute in a word in a short while after a while have a cold have a try 二 定冠词的用法 the 定冠词 the 与指示代词 this that 同源 有 那 这 个 的意思 但较弱 可以和一个名词连 用 来表示某个或某些特定的人或东西 1 特指双方都明白的人或物 Take the medicine 把药吃了 2 上文提到过的人或事 He bought a house I ve been to the house 他买了幢房子 我去过那幢房子 3 指世上独一物二的事物 the sun the

考点分析考点分析 当空格后面的名词是上文提到过 是世界上独一无二的事物 是序数词以及最高当空格后面的名词是上文提到过 是世界上独一无二的事物 是序数词以及最高 级级 例题例题 1 There is picture of elephant on wall 2 This is useful book I ve read it for hour 3 elephant is much heavier than horse 4 doctor told him to take medicine three times day 5 Let s go out for walk 6 It s too hot Open door please 7 There is woman over there woman is Meimei s mother 8 sun rises in east 9 Changjiang River is longest river in China 10 Are you going to do it second time 11 Washington is capital of USA 12 Turners are living at the end of Turner Street 1 a an the 2 a an 第一个空的 a 是泛指 第二个空的 an 是指 一小时 3 An a 这两个空都是泛指 故都用不定冠词 4 The the a 前两个空都是特指 故填 the 后一个空中的 a 相当于 every 或 each three times a day 意为 一天三次 5 a go out for a walk 意为 出去散步 6 the 7 a The 前者泛指 后者特指 8 The the 第一个空用 the 表示太阳是世界上独一无二的物体 第二个空用 the 是因为在方 位词的前面一般用定冠词 9 The the 第一空用 the 是因为在河流名称的前面用定冠词 第二空用 the 是因为在形 容词最高级前面用定冠词 第三空 零 冠词是因为专有名词前一般不加冠词 10 a a second time 意为 再一次 另一次 the second time 意为 第二次 此句填 a 是表 示动作的重复 而不能用 the 表顺序 11 the the 第一个 the 是特指美国的首都 第二个 the 是在由普通名词构成的专有名词前应 加定冠词 12 The the 姓氏的复数 表示 一家人 或 夫妻二人 由普通名词构成的专有名词前 应加 the 2 如果需要填入代词 就要考虑到是人称代词的主格 宾格或物主代词的变化 指示代词的用法 语法语法 人称人称 物主物主 指示代词指示代词 分类分类 英语中代词主要分为人称代词和物主代词英语中代词主要分为人称代词和物主代词 具体形式如下表所示具体形式如下表所示 第第 一一 人人 称称第第 二二 人称人称第第 三三 人人 称称 单数单数复数复数单数单数复数复数单单 数数复数复数 主主 格格 I I wewe youyou youyou hehe sheshe it it theythey人人 称称 代代 词词 宾宾 格格 meme usus

人称代词人称代词 人称代词又分为主格和宾格形式人称代词又分为主格和宾格形式 主格通常做主语 宾格通常做动词或介词的宾语主格通常做主语 宾格通常做动词或介词的宾语 Eg a I m a nurse b b Could you help me c c Mum often takes us to the park on Sunday d d It s a cat We call it Mimi 形容词性的物主代词形容词性的物主代词 相当于形容词 后面要跟名词 指定名词的所属对象 名词性的物主代词名词性的物主代词 相当于一个名词 必须单独使用 后面不能再跟名词 a Your book is small mine is big my book b This is not your pen Yours is on the desk your pen c whose book is that It s hers her book 指示代词指示代词 this 这个 that 那个 these 这些 those 那些 反身代词 反身代词 1 第一 二人称的反身代词是由形容词性物主代词加上 self 或 selves 构成的 如 I myself we ourselves you 单数 yourself you 复数 yourselves 2 第三人称的反身代词是由人称代词的宾格加上 self 或 selves 构成的 如 she herself he himself it itself they themselves one oneself 用法用法 与 by 搭配 当反身代词与 by 搭配时 意为 单独地 没有人帮助的 例如 1 We must finish it all by ourselves 我们必须全靠自己去完成 2 He can swim all by himself 他能独自一个人游泳 简单口语 Help yourself 请随便吃吧 请自己去取吧 Make yourself at home 别客气 Don t upset yourself 别自寻烦恼 考点分析 首先判断分析句子是否缺主语和宾语 在无提示词的语法填空中若出现这样的情况 一般填写的是 代词 考试时分析句子成分才是首要做的 例题例题 1 This is not my pencil box I is in the bag 2 Trees are planted in we country every year which makes our country more and more beautiful 3 Is that bike Miss Gao s Yes it is she book isn t it 4 Help you to some fruit Jack 5 Who taught your brother to surf Nobody He learnt all by he 6 Their English teacher is from America but we is from England 7 Mary s answer is different from I 11 My watch keeps good time What about you 12 He asked me to give he some advice on how to enlarge his present business and he was entire happy about my advice 3 并列的两个或多个单词 短语 或句子之间设空 一般填入并列连词 and but or 等 并列连词并列连词 连词是一种虚词 它不能独立担任句子成分而只起连接词与词 短语与短语或句子与句子作用 连词主要分为两类 并列连词和从属连词 并列连词 1 平行或对等关系的并列连词 and 和 both and 和 两个都 as well as 也 not only but also 不但 而且 neither nor 既不 也不 例 My mother bought me a present and I like it very much 我妈妈买了一件礼物给我 我很喜欢 He can speak not only English but also French 他会说英语还会说法语 2 表转折关系的并列连词 but 但是 例 Lucy likes red but Lily likes white 露西喜欢红的 然而莉莉喜欢白的 3 表选择关系的并列连词 or 或者 either or 要么 要么 注 由 or 连接的句子可以转换为有否定条件构成的主从复合句 Eg Study hard or you ll fail the exam If you don t study hard you ll fail the exam 努力学习 否则你考试会失败的 Either you or he goes 要么你去 要么他去 4 表因果关系的并列连词 so 所以 因此 Eg Kate was ill so she didn t go to school 凯特病了所以没去学校 二 不能同时出现在一个句子中的连词 1 because 因为 so 所以 不能同时出现在一个句子里 只能用其一 eg Because he was tired he couldn t walk here He was tired so he couldn t walk there 因为他 很累 所以走不到这里 2 although though 虽然 but 但是 不能同时出现在一个句子里 只能用其一 但 although though 和 yet 可以同时出现在一个句子里 yet 用作副词 Eg Though he was tired he still worked hard He was tired but he still worked hard 虽然他很累 但是她仍然坚持工作 3 and 和 or 用于否定句中的区别 1 当列举成分是主语 又在否定词之前时用 and 连接 而当列举成分在否定词之后时 用 or 构成完全否定 Eg I can t sing or dance 我不会唱歌 也不会跳舞 Lucy and lily can t speak Chinese 露西和莉莉都不会说汉语 在否定句中 如果所连接的两部分都有否定词那么用 and 而不用 or Eg There is no water and no air on the moon 月球上没有水也没有空气 2 在否定句中 without and 而在肯定句中 without or 构成完全否定 Eg Man can t live without air and water Man will die without air or water 五 由 either or neither nor not only but also 连接两个并列主语时 谓语 动词与较近的主语保持一致 就近原则 填写谓语动词时需要注意 Not only my parents but also I am looking forward to meeting you 不止我父母 连我很也很想见到 你 考点总结 首先确定词与词 句与句之间的关系 然后根据关系选择适当的连词 注意否定词与空格的位置以及特殊单词 without 例题 1 The English would say to their guests Enjoy yourselves when eating and Hope you ve enjoyed after eating 2 He was very tired after doing this for a whole day but he felt very happy since the crop did grow higher 3 Each winner receives a gold medal a diploma and a sum of money 4 He was very tired from doing this for a whole day but he felt very happy 5 Which do you prefer folk music or pop music 6 You may do it yourself or ask someone to help you 7 It was hard work but they really enjoyed it 8 It was our first lesson so the teacher didn t know all our names 9 He is short but strong 10 There is no air or water on the moon 11 He went there by train and but she went there by airplane 12 They made faces and so we all laughed 13 The baby watched and listened 14 I don t like fish but I like chicken 15 My classmates all went to the park but I didn t go 4 两句之间 如果不是并列句 则很可能是主从句 因此需要填入从属连词 what which who how when 等 或者是宾语从句 定语从句或者是状语从句的连接词 这种空格需要同学们根据句子结构 分析 到底是什么从句 从而选择合适的从属连词 从属连词从属连词 语法语法 从属连词分为两大类 即引导状语 定语从句的从属连词和引导名词性从句 主语 宾语 表语 同位语从句 的从属连词 引导名词性从名的从属连词 宾语从句宾语从句 宾语可由名词 代词或名词短语或句子来充当 当一个句子充当宾语时 这个句子称为宾语从句 1 由 that 引导的宾语从句 that 只有语法作用 没有实在的意义 例如 He said that he wanted to stay at home She doesn t know that she is seriously ill I am sure that he will succeed We all know that the earth moves around the sun 众所周知 地球围绕太阳转 宾语从句 I m sorry that you can t come 很遗憾你不能来 宾语从句 2 由连接代词 who whom whose what which 连接副词 when where why how 引导的宾语从句 这些连接代词和连接副词在宾语从句中充当某个成分 例如 Do you know who whom they are waiting for 宾语 He asked whose handwriting was the best 定语 Can you tell me where the No 3 bus stop is 表语 I don t know why the train is late 状语 3 由 if 或 whether 引导的宾语从句 if 和 whether 在句中的意思是 是否 例如 I want to know if whether he lives there He asked me whether if I could help him 注意 句子中出现 or not 时 只用 whether 4 形式宾语 it 如宾语从句后有补语 要用形式宾语 it 来代替 而将从句放到补语的后面去 e g He has made it clear that the meeting will not be hold 考点总结 1 首先分析句子成分空格前面不含有宾语 双宾语情况除外 则一定为宾语从句 2 从句部分是完整的句子则用 that whether if 3 若从句句子成分不完整则根据句意判断是连接代词还是副词 地点 时间 原因 方式 例题 1 I don t know when Mr Green will come to see us He ll help us with our English 2 Be careful Don t break the bottles Do you hear what I said David 3 I find it important that we practice English every day 4 He asked me who told me the accident 5 I hardly understand what he has told me 6 Can you tell me when you were born Betty 7 I don t know if they have passed the exam 8 I hardly understand that he has told me 9 I don t know whether he still lives here after so many years 10 Do you know what they listened to yesterday evening 定语从句定语从句 定义 在复合句中 修饰某一名词或代词的从句叫做定语从句 如 1 The man who lives next to us is a policeman 2 You must do everything that I do 上面两句中的 man 和 everything 是定语从句所修饰的词 叫先行词 定语从句放在先行词的后面 引导定语从句的词有关系代词 that which who 宾格 who 所有格 whose 和关系副词 where when why 关系词常有三个作用 1 引导定语从句 2 代替先行词 3 在定语从句中担当一个成分 二 关系代词引导的定语从句 1 who 指人 在从句中做主语 1 The boys who are playing football are from Class One 2 Yesterday I helped an old man who lost his way 2 whom 指人 在定语从句中充当宾语 常可省略 1 Mr Liu is the person whom you talked about 注意 关系代词 whom 在口语和非正式语体中常用 who 代替 可省略 3 The man who whom you met just now is my friend 3 which 指物 在定语从句中做主语或者宾语 做宾语时可省略 1 Football is a game which is liked by most boys which 在句子中做主语 2 This is the pen which he bought yesterday which 在句子中做宾语 4 that 指人时 相当于 who 或者 whom 指物时 相当于 which 在宾语从句中做主语或者宾语 做宾语时可省略 5 The people that who come to visit the city are all here 在句子中做主语 6 Where is the man that whom I saw this morning 在句子中做宾语 5 whose 通常指人 也可指物 在定语从句中做定语 1 he has a friend whose father is a doctor 2 i once lived in a house whose roof has fallen in 关系副词关系副词 why 关系副词 why 主要用于修饰表示原因的名词 主要是 the reason 同时它在定语从句中用作原因状语 如 We don t know the reason why he didn t show up 我们不知道他为什么没有来 She didn t tell me the reason why she refused the offer 她没跟我讲她拒绝这项工作的原因 与关系副词 when 和 where 不同 why 可以换成 that 或省略 如 That s one of the reasons why that I asked you to come 这就是我请你来的原因之一 另外 与关系副词 when 和 where 可以引导非限制性定语从句不一样 why 只能引导限制性定语从句 不能引 导非限制性定语从句 如 他失去工作的主要原因是他喝酒 误 The main reason why he lost his job was that he drank 正 The main reason why he lost his job was that he drank 关系副词关系副词 when 关系副词 when 主要用于修饰表示时间的名词 同时它在定语从句中用作时间状语 如 There comes a time when you have to make a choice 你必须作出抉择的时候到了 Gone are the days when they could do what they liked 他们为所欲为的日子一去不复返了 We ll put off the picnic until next week when the weather may be better 我们将把野餐推迟到下星期 那时天气可能会好一点 注意不要一见到先行词为时间名词 就以为一定要用关系副词 when 来引导定语从句 同时还要看它在定语 从句中充当什么成分 如果在定语从句中用作时间状语 就用 when 如果在定语从句中不是用作时间状语 而是用作主语或宾语 那就不能用 when 而要用 that which 等 如 Don t forget the time that which I ve told you 不要忘记我告诉你的时间 关系代词 that which 在定语从句中用作动词 told 的宾语 正因为是用作宾语 所以也可以省略 关系副词关系副词 where 关系副词 where 主要用于修饰表示地点的名词 同时它在定语从句中用作地点状语 如 This is the village where he was born 这就是他出生的村子 That s the hotel where we were staying last summer 这就是我们去年夏天住的旅馆 Barbary was working in Aubury where she went daily in a bus 巴巴拉在奥伯里工作 每天得坐公共汽车 去上班 与前面 when 的情况一样 注意不要一见到先行词为地点名词 就以为一定要用关系副词 where 来引导定语从 句 同时还要看它在定语从句中充当什么成分 如果在定语从句中用作地点状语 就用 where 如果在定 语从句中不是用作地点状语 而是用作主语或宾语 那就不能用 where 而要用 that which 等 如 He works in a factory that which makes TV sets 他在一家电视机厂工作 关系词选择 只用只用 that 不用不用 which 1 当先行词是或被序数词 最高级 不定代词修饰时 关系词用 that 不用 which 2 当先行词既有人又有物时 用 that 3 当先行词带有 the only the very the same the last the one 等词时 用 that 不用 which 4 当主句中有 who 或 which 时 为避免重复用 that 5 当句子是一个特殊疑问句 且引导词为 which 时 最好用 that 6 当只用 who 不用 that 如果先行词是 those they all person people he anyone one 时用 who 不用 that 只用只用 which 不用不用 that 1 当主句先行词后有介词时 用 which This the one of which I m speaking 2 非限定性定语从句 用 which 3 描述句中一般用 which Beijing which was China s capital for more than 800years 4 those 复数名词之后 多用 which Shopkeeper want to keep a number of those goods which sell best 5 当前面已有一个定语从句 且连接词为 that 时 宜用 which 注意 1 there be 句型中 指人用 who 指物用 that 2 当主句中缺少主语或表语时 用 the one 前面已有一个定语从句 且连接词为 which 时 宜用 that 考点分析 首先分析句子 如果空格前面的先行词中做了主语 宾语 定语时 判断为定语从句 最后根据修饰 人还是物来选择从属代词 例题例题 1 I still remember the night I first came to the house 2 I ll never forget the day we met each other last week 3 Mr Black is going to Beijing in October is the best season there 4 I will never forget the days I spent with your family 5 I ll never forget the

从属连词来引导 与主句连接起来 若置于句末 则前面不加逗号 辨析 定语 用来修饰名词或代词 因为它修饰这两种词类 而名词和代词有可以作主语 还可以作表语和宾 语 所以定语的位置很灵活 凡是有名词 代词的地方都可以有定语 例 The black bike is mihne black 作主语 bike 的定语 状语 用来修饰动词 形容词或副词 一般表示行为发生的时间 地点 目的 方式 程度等意义 常 由副词 介词短语 不定式或相当于副词的词语或短语来表示 状语一般放在句末 但有的可以放在句首 句中 例 He did it carefully 副词 carefully 作状语 根据意义和作用 状语从句可分为时间原因条件等几种 下面我们就来分析一下这几种状语从 句 1 时间状语从句时间状语从句 一般来说 时间状语从句常由连词 when before after as soon as 或 until 引导 I will go to the cinema as soon as I finish my homework 我一完成作业就去电影院 When I grow up I will join the army 当我毕业了 我就要去参军 2 条件状语从句条件状语从句 条件状语从句常由 if 如果 unless 除非 或 as long as 只要 来引导 同样适用于 主将从现 如 We will
