七年级上册第二单元知识点一.指示代词1.指示代词的近指:时间或空间上离的近的人或物this、that、these、those这四个词是指示代词,his/these。
this为单数指示代词,these为复数指示代词。
①this,这个,(指代单数)This girl is Mary over there.♥This is Mary speaking.我是玛丽。
(电话用语)②these这些(指代复数)I like these flowers.2.指示代词的远指:时间或空间上离的远的人或物①that那(指代单数)He was young at that time.(时间)②those那些(指代复数)That boy is in Class5.3.指示代词单复数转化this/that指代单数名词,these/those指代复数名词。
this和these离近的人或事物,that和those离远的人或事物。
4.指示代词构成的疑问句及其答语:①一般疑问句♦-Is this your photo?-Yes, it is. /No,it isn’t.♦-Is that your book?-Yes, it is. /No,it isn’t.♦ - Are these your kids? -- Yes, they are./No,they aren’t.♦- Are those your flowers? -- Yes, they are./No,they aren’t.②特殊疑问句♦- Who is this?- It's my dad.- Who is this?- It's my dad.♦-Who’s that?-This is Bob speaking.二.Who1.Who pron.谁,特殊疑问词Whom宾格Whose所有格2.Who 与be 缩写Who is=who’sWho are=who are3.who特殊疑问句3.1单数-Who’s she?-She is my sister.3.2复数-Who’re they?-They are my parents.三.名词复数1. 名词的分类名词分为可数名词不可数名词。
Unit 2 This is my sister一.重点词汇1.parent父(母)亲= father or mother, 经常用复数形式”parents”= mother and father.As a parent, you should be kind to your kids.My parents go to work by car.2.family n. 家,家庭(1)family当作整体用时,是单数,谓语动词用单数。
I have a big family.(2)family 强调家庭成员时,是复数含义,谓语动词用复数形式。
My family are watching TV now.(3)family 复数形式是families, 表示”几个家庭”These families are very happy. 这些家庭都很幸福。
3.well(1)作感叹词,可以表示不同的含义Well, I’ve never heard such a story!啊,我从没听过这样一个故事!(表示惊讶)Well, maybe you are right.好吧,或许你是对的。
(表示认可某种事情)(2)作形容词,表示“健康的”I’m well, thank you! 我很好,谢谢你!(3)作副词,意为“好地,令人满意地”He plays tennis very well. 他网球打得非常好。
4.Have a good time!=Have a good day!(祝福语)玩的开心,过得愉快。

名词复数形式的读音分中情况:1.在轻辅音后面读【S】;2.在浊辅音和元音后面读【Z];3.在t,d的后面分别读【ts】,【dz];4.在s,z,sh,ch,ge等后面一般读作【iz】。
规则动词后加-ed的读音情况如下:1。
在轻辅音后面读【t】;2.在浊辅音和元音后面读【d];3.在t,d的后面分别读【id】;名词变复数,动词第三人称,过去式读音张东启无论是名词变复数、动词第三人称单数形式,还是动词加“ed”的过去式,总的发音规律就是“清清浊浊元也浊”,就是在清辅音后读清辅音,在浊辅音后读浊辅音,在元音后也读浊辅音。
动词第三人称单数词尾变化有三种形式。
(1)一般动词在词尾加-s,-s在清辅音后读/s/,在浊辅音或元音后读/z /,ds读/dz/,ts读/ts/。
如:help→helps/helps/,know→knows/nEuz/,get→gets/gets/,read →reads/ri:dz/(2)以字母s,x,ch,sh或有些以o结尾的动词加-es,-es读/iz/。
如:guess→guesses/'gAsiz/,fix→fixes/'fiksiz/,teach→teaches/'ti:tFiz/,wash→washes/'wRFiz/注意:go→goes/gəuz/,do→does/dΛz/(3)以辅音字母+y结尾的动词,先变y为i,再加-es,-ies读/iz/。
如:carry→carries/'kæriz/,fly→flies/flaiz/注:在play→plays/pleiz/,say→says/sez/中,字母y前为元音字母,第三人称单数形式直接在动词后面加-s。
(4)特殊词例外。
如:be→is,have→has动词过去式和过去分成过去式的发音是由单词的最后一个音素来决定的:1.如果该单词以清辅音结尾,如/k/,/p/等,则读作/t/,例如looked读作/t/.2.如果该单词以浊辅音结尾,如/n/,/b/等,则读作/d/,例如abandoned读作/d/.3.如果该单词以字母t或字母d结尾,则读作/id/,例如started读作/id/.4.如果该单词以元音结尾,则读作/d/,例如studied读作/d/.以上是过去式读音的一般规则,英语中还有许多不规则的动词,他们的过去式及发音就得靠你去记忆了,如buy过去式为bought,等等名词复数的构成和读音可数名词有单数(Singular Form)和复数(Plural Form)两种形式。
名词复数变形规律1.绝大多数的可数名词的复数形式,是在该词末尾加上后辍-s。
读音变化:结尾是清辅音读[s],结尾是浊辅音或元音读[z]。
例:friend→friends; cat→cats; style→styles; sport→sports; piece→pieces2.凡是以s、z、x、ch、sh结尾的词,在该词末尾加上后辍-es构成复数。

例:tomato→tomatoes; potato→potatoes; torpedo→torpedoes;bingo→bingoes反例:silo→silos; piano→pianos(外来词); photo→photos; macro→macros(缩写词)5.以-f或-fe结尾的名词,多为将-f或-fe改变为-ves,但有例外。

例:knife→knives; life→lives; leaf→leaves; staff→staves; scarf→scarves反例:roof→roofs6.以-us结尾的名词(多为外来词),通常将-us改变为-i构成复数。
读音变化:尾音[Es]改读[ai],其中[kEs]要改读为[sai],[gEs]要改读为[dVai]。
例:fungus→fungi; abacus→abaci; focus→foci; cactus→cacti; cestus→cesti籽伽21:53:097.以-is结尾的名词,通常将-is改变为-es。

1. 可数名词(Classifiable Nouns):可数名词可以用数字进行计数,并且可以有单数和复数形式。
如:book(书),apple(苹果),dog(狗),student(学生)等。
2. 不可数名词(Uncountable Nouns):不可数名词不可以用数字进行计数,只有单数形式。
如:water (水),music(音乐),money(钱)等。
二、冠词(ARTICLES)冠词是用于修饰名词的词语,在英语中主要有三种冠词:定冠词、不定冠词和零冠词。
1. 定冠词(The Definite Article):定冠词是指特指某个人或物的冠词,只有一个形式,即 "the"。
如:the book(这本书),the cat(这只猫)等。
2. 不定冠词(The Indefinite Article):不定冠词是指泛指人或物的冠词,有两个形式,即"a" 和"an"。
如:a book(一本书),an apple(一个苹果)等。
3. 零冠词(Zero Article):零冠词是指名词前没有任何冠词修饰的情况,也可以表示泛指。
如:I like flowers(我喜欢花)。
三、形容词(Adjectives)形容词是用来描述或修饰名词的词语,通常位于名词前面。
形容词可以分为具体形容词和抽象形容词。
1. 具体形容词(Concrete Adjectives):具体形容词用来描述或修饰可以通过感官观察得到的名词。
