1、1英语语法知识汇总-五 B第一课时名词复数重点:名词的复数变化规则。 难点:灵活运用。这里强调两点:不可数名词都默认为单数,所以总是用 is.1.一般+s 如 mapmaps , bagbags 等 2.特殊:以 s,x,sh,ch 结尾的单词+es 如 busbuses , watchwatches 等; 3.以辅音字母+y 结尾,去掉 y 加上 ies,以元音字母 +y 结尾加上 s 4.以 f 或 fe 结尾,去掉 f/fe 加上 ves。如 knifeknives leafleaves wolfwolves wifewives lifelives thiefthieves 5.有时可数
2、,有时不可数:典型例词:fish 当它解释为鱼肉时是不可数名词,当它解释成同一种鱼时,单复数同形,复数即为 fish,当它解释为不同一种鱼时,+es,即为 fishes. 6.以 o 结尾,a) photophotos ,pianopianos,radioradios,zoozoos b)加 es 的名词有:potatopotatoes tomatotomatoes 7.特殊词:child-children(小孩) man-men(男人) woman-women(女人) 8.单复数同形(单数和复数一样)people(人)sheep(绵羊) deer(鹿)) 9.国人变复数 :口诀:中日不变英法
3、变,其余 s 加后面。 Chinese-Chinese Japanese-Japanese Englishman-Englishmen Frenchman-Frenchmen American-Americans 等等 10. 字母、数字、引语、缩略语变复数,在其后加 s 或s。 eg. There are two ts in the word 各种不同情况 变化方法 例词一般情况 直接加-s book-books bag-bags cat-cats bed-beds以 s. x. sh. ch结尾 加-esbus-buses box-boxes brush-brushes watch-wat

9、ing country. _is in the east of asia. ( its )人称代词 物主代词单数 复数 单数 复数 主格 宾格 主格 宾格 形容词性 形容词性第一人称 I(我) me we(我们) us my(我的) our(我们的)第二人称 you(你) you you(你们) you your(你的) your(你们的)he(他) him his(他的)she(她) her her(她的)第三人称it(它) itthey(他/她/它们)themit(它的)their(他/她/它们的)33. what day is _ today? _ is thursday.

( they)四、用括号中的适当形式填空(1)are these _(you)pencils?yes, they are _(our).(2) whose is this pencil?its _(i).(3)i love _(they)very much.(4)she is_(i)classmate. 第三课时冠词有 a、an、the。 a 和 an 的区别:an 用于元音音素(一般就是元音字母 a、e、i、o、u)前,a 用于辅音音素前。基本用法当代语法把冠词分为不定冠词、定冠词和零冠词(即不用冠词)三种。冠词是
14、一种虚词,起限定作用,是最主要最典型的限定词,放在名词(或名词化的形容词分词)前指近处 指远处单数 this (这个) that (那个)复数 these(这些) those(那些)4面,说明其所指的人或物。此类问题很多人都会陷入误区,认为见到 a,e,i,o,u 前面就该用不定冠词 an,如果不是就用a,这是不对的哦,其实正确的理解应该是当单个字母或单词发音以元音开头就用 an,否则用a,可以说当用 an 时与是否出现元音字母无关。 a 用于辅音前;an 用于元音前。一般说来,元音字母发元音,辅音字母发辅音。 但需请注意以下 3 点: (1 拼写以辅音字母开头读音却以元音开头的单词 hour
15、, honest, honor 等单词的拼写虽然以辅音字母 h 开头,但其读音却以元音开头,因此,前面要用 an。 (2) 拼写以元音字母开头读音却以辅音开头的单词 useful, university, usual, united, European, one-eyed, one-way 等单词的拼写虽然以元音字母开头,但其读音却不以元音开头,因此,前面要用 a。 (3)在26个英文字母中, a, e, i, o, f, h, l, m, n, r, s, x 这 12个字母的读音是以元音开头的,其余字母的读音则是以辅音开头的1. In America, _ car is _ popular
16、 means of transportation(交通设施).A. the, the B. a, the C. the, / D. the, a2. - What happened? - They left in such _ hurry that they forgot to lock _ door.A. a, a B. a, the C. /, the D. /, a3.

17、e D. a, a4. I ordered _ book some time ago. _ book has arrived.A. a, The B. the, A C. a, A D. /, The5. Mr Smith is _ European and his wife is _ American.A. an, an B. a, a C. a, an D. an, a第四课时特殊疑问句表示疑问,有疑问词(在开头),回答有很多种可能。常用疑问词: 疑问词 意思 用法What time 什么时间 问具体时间,如几点钟Who 谁 问人Whose 谁的 问主人5Where 在哪里 问地点What
18、 什么 问东西、事物What colour 什么颜色 问颜色How old 多大年纪 问年纪How many 多少数量(可数名词) 问数量How much 多少钱;多少数量(不可数名词) 问多少钱或数量(不可数)把下面的句子变成否定句。1.She is watching TV now. 2.We go to school on Sunday. 3.His father works hard. 4.Jacks mother is a nurse. 5.The cat runs fast. 把下列句子改为一般疑问句。1. We need some masks. 2. They like makin
19、g the puppet. 3. Su Hai and Su Yang live in a new house. 4.I put a book on my head. 6.They sing “In the classroom”together. 第五课时一般现在时表示某动作或者某状态是经常发生的事情,或者是自然规律。 主语+be 动词(am, is , are) 主语+动词原形(注意动词要根据主语变三单)(1)一般现在时中的 be 动词:一般用原形:am is aream 用于第一人称单数(I);is 用于第三人称单数(he she it 和其他人名或称谓,如:Ben his sister
20、等);are 用于第二人称单数(you)和所有复数(包括第一人称复数 we、第二人称复数 you;第三人称复数 they 和其他复数,如 the children 、 his parents 等)。6(2)一般现在时中的动词:第一种情况:主语是第三人称单数(he she it 和其他,如 Helen 、her cousin 等),动词后一般加 s 或 es。第二种情况:主语不是第三人称单数,动词都用原形。(4)一般现在时判断依据(如何判断一个句子是一般现在时):be 动词是 am、is、 are 动词用原形或加 s、es没有时间状语或有 usually、often、everyday、somet
21、imes 等不是具体的时间专项练习:一、 单选1 Jenny _ in an office. Her parents _in a hospital.A work works B works work C work are working D is working work2 One of the boys_ a black hat.A have B there is C there are D has3 We will go shopping if it_ tomorrow.A dont rain Bdidnt rain Cdoesnt rain Disnt rain4 He said the

23、s (play) football very well.2 Danny gos (go) to school at 7:10.解析:1 以辅音字母加 y 结尾的动词变单三人称形式才能把 y 换成 i 再加 es;2 与名词变复数不同,变第三人称形式以 o 结尾的词要加 es.2、在句式变换时易出错例:1 Does Jenny has (has) a good friend?2 Brian doesnt lives (not live) in China.解析:单三人称做主语的一般现在时做句式变化时,可记住如下口诀:“见助动,用原形” 。此口诀也可推广用于一般过去时态中。e.g. He didn
24、t go home yesterday.对 do 的理解易出错例:We dont (not do) our homework in the afternoon.7解析:do 是一个比较难理解的词,它有三个含义:a)是所有行为动词的总称;b) 是助动词,无实义;c) 是一个具体的行为动词“做,干”。此句中给出的 do 指“ 做,干” , not 指把此句变为否定句,故须在 do 前加助动词 dont。五、对主语的数判断有误例: Li Ming with me are (be) in Beijing.解析:表面一看是“我和李明两个人在北京” ,但 with 在此做伴随状语,不能做主语,故用 is.
25、另外,宾语从句中,从句部分若是表示客观真理,不管主句是何时态,从句都要用一般现在时;在时间和条件状语从句中,主句表将来,从句要用一般现在时。第六课时现在进行时(1)构成形式:Be 动词+动词的 ing 形式这里强调一点,两者缺少其中任何一种都不可以构成现在进行时。(2)现在进行时表示动作正在进行或事情正在发生。(3)有用的依据:一个句子中既有 be 动词,又有动词,且动词加了 ing 该句是现在进行时(4)句中往往有 now、look、listen 等词。动词现在分词的变化见下表:词尾情况 变化方式 例词一般情况 加ingplay 玩playing do 做 doinggo 去going ju
