Lesson One :名词、冠词和代词的用法第一部分:语法讲解一、名词用法讲解1.名词的数:英语中的名词可以分为可数名词(countable noun)和不可数名词(uncountable noun)。
如:“book, pen, cup”都是可数名词。
“furniture, milk, air”都是不可数。
在这里强调一点:英文中名词的可数和不可数是不能按照我们汉语的逻辑思维去理解的。
比如汉语中的“家具”,我们常说:一件家具。
但是英文中“furniture”是不可数的。
还需要注意的一点是,英语中有很多的名词既可以用作不可数名词也可以用作可数名词,只不过此时词义往往不同。
如:There is plenty of room for everyone to sit down in this room. 这房间有足够的空间让每个人坐下。
(第一个room作为空间是不可数的;第二个room作为房间是可数名词)b.以o结尾的名词,直接加-s,如:photo-photos, bamboo-bamboosc.以f 或者fe结尾,直接加-s,如:belief-beliefs, cliff-cliffs可数名词复数的不规则变化:1)变换元音或者加后缀如:tooth-teeth (牙齿)foot-feet (脚)mouse-mice (老鼠)woman-women(妇女)ox-oxen(公牛)child-children(孩子)2)单复同形如:cattle (牛)Chinese (中国人)sheeep (羊)reindeer (驯鹿)means (方法)3)外来语的复数形式拉丁语:datum-data (数据)medium-media(媒介)希腊语:crisis-crises(危机)phenomenon-phenomena(形象)不可数名词的数:不可数名词通常没有复数形式,但可以借助单位词来表示一定的数量。
如:a piece of paper一张纸 a slice of meat一片肉a fit of cough一阵咳嗽 a ripple of laughter一阵笑声2. 名词的所有格名词的所有格有两种形式:一是在名词后面加’s的形式,二是在介词of后加上名词的形式。
知识要点:英语语法专题一、冠词The Article冠词是一种虚词,放在名词的前面,帮助说明名词的含义。
冠词分不定冠词(The Indefinite Article)和定冠词(The definite Article )两种。
a (an) 是不定冠词, a 用在辅音之前:如 a book, a man; an 用在元音之前,如:an old man, an hour, an interesting book 等。
the 是定冠词。
一、不定冠词的用法1、指人或事物的某一种类(泛指)。
这是不定冠词 a (an)的基本用法。
如:She is a girl. I am a teacher. Please pass me an apple.2、指某人或某物,但不具体说明何人或何物。
如:He borrowed a story-book from the library.A Wang is looking for you. 一位姓王的同志正在找你。
3、表示数量,有“一”的意思,但数的概念没有one 强烈。
如:I have a mouth, a nose and two eyes.4、用于某些固定词组中。
如:a bit, a few, a little, a lot of, a piece of, a cup of, a glass of, a pile of, a pair of, have a good time, for a while,for a long time 等。
5、用在抽象名词前,表具体的介绍——a + 抽象名词,起具体化的作用。
如:This little girl is a joy to her parents. 这女孩对她父母来说是一个乐趣。
It is a pleasure to talk with you. 跟您交谈真是一件愉快的事情。
It is an honour to me to attend the meeting. 参加这个会,对我来说是一种荣誉。
雅思基础+写作语法总结一.时态问题:四种时态:一般现在时,现在进行时,现在完成时,一般将来时打工对一个人的将来的事业有深远的影响。
(过去现在未来都有影响,客观,单数)Taking part-time jobs exerts profound impacts on one’s future career.国际旅游业促进经济发展。
(过去现在未来都促进,客观,单数)International tourism promotes the economic development.现在进行时:表示正在进行的动作或存在的状态。
现在进行时表示动作发生的时间是“现在”,表示逐渐的过程is developing rapidly/dramatically.现在完成时: 1.表示结果和影响,一般表示变化大,发展了。
2.表示过去的动作或状态持续到现在注意常用搭配:In recent years, In the past decades…最近几十年期间,世界发生了巨大的改变。
In the past decades, dramatic changes have taken place in the world.最近几年,科技极大的改变了人们的生活。
In recent years, technology has reshaped people’s life.犯罪率已经急剧上升了。
The crime rate has increased sharply.will do电脑将会在教育过程中起越来越关键的作用,但是它们绝对不能在教室中取代老师的地位。
Computers will play an increasingly critical role in education, but it is not possible that they could replace teachers in the classroom. /but it is impossible for them to replace teachers in the classroom.二.语态问题:常见被动语态结构:be done一般现在时Am, is, are done正在进行时Is being done现在完成时Have/has been done一般将来时Will be done应该把优先权给教育Priorities should be given to education.很多动物的栖息地正在被破坏Many habitants of animals are being destroyed书信已经逐渐被先进的科技所代替Letters have been replaced by advanced technology gradually.三.简单句:1)简单句:主流句型,主要结构会使用就可以了。
