3、s读音为z。(2)以s,x,ch,sh结尾的词名词变复数时,要在词尾加es.eg.beachbeaches,brushbrushes,busbuses,boxboxes(es读音为iz(3)以“辅音字母+y”结尾的名词,先变y为i,再加es.eg.citycities,familyfamilies,documentarydocumentaries,countrycountries,strawberrystrawberries(ies读音为iz)(注：以“元音字母+y”结尾的词，直接在词尾加-s.eg.boys,holidays,days)(4)以o结尾的名词，变复数时情况如下：,.tomato

7、o boxes Of pencils2.不可数名词一般没有复数形式，它的“量”的表示方式如下。(1)表不定数量时,一般用much,(a)little,a lot of/lots of,some,any等词修饰。eg,much money,a little bread(2)表确定数量时,一般用“数词+量词+of+不可数名词。如：two/three/+量词复数十of+不可数名词。eg.a bag Of rice,two glasses Of milk,four bottles Of water3.有些名词既可作可数名词也可作不可数名词，但词义有所不同。eg： fruit水果fruits表示不同种类

11、难的是语法，因为英语的语法跟汉语的语法有很大的不同。初中英语连词有很多种。下面为大家讲解一下初中英语连词的用法。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，短语与短语以及句与句的作用。连词主要可分为两类：并列连词和从属连词。第一类表示并列关系的连词并列连词：并列连词用来连接平行的词、词组和分句。1)and 和判断改错：(错) They sat down and talk about something.(错) They started to dance and sang.(错) I saw two men sitting behind and whisper there.(对) T

12、hey sat down and talked about something.(对) They started to dance and sing.(对)I saw two men sitting behind and whispering there.解析：第一句： and 连接两个并列的谓语，所以 talk 应改为 talked。第二句：and 连接两个并列的动词不定式，第二个不定式往往省略to，因此sang 应改为 sing。第三句：and 连接感观动词saw 后面的用作的宾补的两个并列分词结构，因此whisper应改为whispering。注意：1. and 还可以和祈使句或名词词组

13、连用表示条件。(or也有此用法)Make up your mind, and youll get the chance.= If you make up your mind, youll get the chance.One more effort, and youll succeed.= If you make one more effort, youll succeed2, A and B 当表示整体或者指同一人时谓语动词用单数, 当and连接的单数名词前分别有each，every，many等词修饰时，谓语也用单数。bread and butter a knife and forkThe

14、mother and teacher is very strict with her son.No teacher and no student is allowed to smoke in class.3. and连接的是两个相同意思的词，表示“渐渐”，或加强语气Read it again and again2)both and两者都She plays (both) the piano and the guitar.3) neithernor 意思为既不也不谓语动词采用就近原则，与nor后的词保持一致。Neither you nor he is to blame.4)not onlybut

15、(also)不但而且She plays not only the piano, but (also) the guitar.注意： not only but also 关联两个分句时，一个分句因有否定词not 而必须倒装。Not only does he like reading stories, but also he can even write some.5) as well as 以及，也，与同样The teacher, as well as the students, is interested in the activity.比较and和or1) 并列结构中，or通常用于否定句，a

16、nd用于肯定句。2) 但有时and 也可用于否定句。请注意其不同特点：There is no air or water in the moon.There is no air and no water on the moon.在否定中并列结构用or 连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。第二类表示选择关系的连词1) or意思为或则。Which do you prefer, tea, coffee, or juice ?2) eitheror意思为或者或者 。注意谓语动词采用就近原则。Either you or I am right.3) or else/ other

17、wise 否则Be silent, or else you will be kicked out.I am tired, otherwise, I would play.第三类表示转折或对比关系的连词1) but 但是 He is rich but unhappy.while 然而，表示对比意味 Some people love cats, while others hate them.yet 然而 She said she would be late, yet she arrived on time.however 然而，可是，不过 She does not like him, howeve

18、r, I like him.2) notbut 意思为不是 而是not 和but 后面的用词要遵循一致原则。They were not the bones of an animal, but (the bones) of a human being.第四类表因果关系的连词1) for 因为，做并列连词使用时，是在对先行的句子补述原因或者理由，只可以连接句子与句子，通常不置于句首。He is absent today, for he is ill.2) so, therefore 因此He hurt his leg, so he couldnt play in the game.I think,

19、 therefore I am3)then 那么，因而Hide behind the wall, then they wont see you.注意：a. 两个并列连词不能连用，但therefore, then, yet.可以和并列连词连用。You can watch TV, and or you can go to bed.He hurt his leg, and so / and therefore he couldnt play in the game.b. although yet，但although不与 but连用。(错)Although he was weak, but he tr

20、ied his best to do the work.(对)Although he was weak, yet he tried his best to do the work.从属连词从属连词不同与并列连词，只能用来引导从句，而不能引导词或者词组。从属连词一般可以引导名词性从句和状语从句。第一类引导名词性从句的从属连词1) that 引导宾语从句或间接引语时，可省略。引导主语从句时不可以省略。He said (that) he would come. 宾语从句His mother told me (that) he is a good boy. 间接引语That she is still

21、alive is true. 主语从句2) if/whether 是否I wonder if he is at home.I ask him whether he would come.注意：只可以用whether的情况介词后面 It will depend on whether it rains tomorrow.whetheror not 固定搭配 Let me know whether you come or not.动词不定式前 I dont know whether to accept his advice.第二类引导状语从句的从属连词1) 连接时间状语从句的从属连词before 在

24、关系 I do it because I like it.for 表因为，表间接的原因，用于说明，解释 I soon went to sleep, for I was tiredsince 表原因，比because弱，比as强，表一种已知的，显然的理由，常译为“既然as 表原因时，意义最弱 As you are in poor health, you should do more exercises4) 连接结果状语从句的从属连词sothat 如此以至于 He is so kind that everybody likes him.suchthat He is such a kind man

25、that everybody likes him5) 连接目的状语从句的从属连词that / so that / in order that 为了Speak clearly that/so that/ in order that they may understand you.6) 连接条件状语从句的从属连词if 如果 If it rains tomorrow, we wont go on a picnic.unless 除非 (如果不 ) He will come unless it rains.in case 万一 You may call this number in case I am

28、ly yesterday. 他是昨天才到的。There were clothes lying here and there on the floor. 地板上到处都是衣服。I have been terribly worried about you all day. 我一整天都非常为你担心。She plays the piano very well. 她钢琴弹得很好。The boy is always asking his parents for money. 那个男孩老是向他父母要钱。She never goes to the cinema. 她向来不看电影。 修饰形容词、副词、介词短语，一
