What bad weather! I bought a new bike. 形容词可在系动词后,作表语(划线部分): The girl is kind. His face turned red. It tastes sweet. 2副词(划线部分)修饰动词、形容词、副词,也可修饰整个句子。 He ran quickly. Please speak loudly. Tim lives alone. 修饰动词 She is very angry. He felt too tired. I’m so lucky. 修饰形容词 He got up quite early. She did it very well. 修饰副词 Unluckily, I failed the English exam. 修饰整个句子26.everyday与every day: everyday是形容词,后接名词,“日常的”。He is practicing everyday English. every day是副词,作时间状语,“每天”。We speak English every day.

Ⅱ 初中英语知识:这样表达为什么不对

表示地点的时候应该用AT...而不是OF

of的使用方法没有掌握。。
我感觉's有一种所属的含义,比如A's B表示B是属于A的,如Mary's bag
而B of A一般表示B是A的一个特征,如the size of father's coat

eg. pictures of Mary
Mary's pictures
两者都可译为“玛莉的相片”但具体意思不同。
前者表明照片上的人是玛莉,后者表明照片归玛莉所有。
总的来说,of倾向于修饰的意思。例如sword of moon——月之剑,moon就起到了修饰sword的作用。再如the city of Beijing——北京城,Beijing就起到了修饰the city的作用。
而's则倾向于归属的意思。
其实有些情况二者也不是不可以混用的。

Ⅲ 初中英语知识点问题

1.other后接单复数均可,other one或other two students.
others只能作代词,意思是“其它的人(物或事等)”,常用来泛指。
the other也是既能作形容词,又能作代词。但它一般用来表示总数为二时的“另外一个”,经常与one搭配。 other也能既作形容词又可作代词,意思是“别的,另外的”。
the others也只能作代词,意思与others相近,但常用来特指。
the rest其余者;剩余部分another作形容词时,是指在原有的基础上再加一(些),表示“再一(些)”或“另外一个(些)”的意思,在心理上至少有三个。 another还可作代词,意思与作形容词时一样。它前面不能加任何冠词,后面也不能加s 2.选A 这里面A是修饰物的 C是修饰人的 题目问的是CARD 是物品 所以选A3.in one's sixties是固定用法 B项没有这种用法
over sixties一般用作名词 与for连用 例: It costs£3.70 for grown-ups ,£2 for children and less for over sixties4.be familiar to 物作主语 be familiar with 人作主语例:Shanghai is not familiar to me. I am still not familiar with Shanghai.5.这道题是应该用to 但其他时候不是一定用to了 这是方位介词的问题 方位介词的分辨比较,一般是in / to/ on 三者的的区别

I. "in the+方位名词"指的是小范围在一个大范围的里面,表示"在某范围之内",强调两者的包含关系。如:

Beijing is in the north of China. 北京在中国的北部。

II. "on the+方位名词"指的是一个范围紧挨着另一个范围,表示"两地接壤",强调两者为相邻关系。如:

Korea is on the northeast of China. 朝鲜在中国的东北面。

III. "to the+方位名词"指的是一个范围和另一个范围之间隔段距离,表示"在某范围之外",强调两者是远离关系。如:

Japan is to the east of China. 日本位于中国的东边。 6.go to college意思是上大学 表示的是泛指 英语有很多习惯用语都不用冠词的, 如:“go to school上学”、“go to bed睡觉”等等。 go to the college则表示特指 是指上某一所大学 需要根据语境具体分析7.in hospital表示住院 说明主语因生病而住院 in the hospital表示在医院 不是住院 只是在医院工作或去看望病人 希望能帮助到你 只是简练的说了一下 不清楚的话再问也OK

⑦ “be to +动词原形”表示按照计划将要发生的事情。如:An angel came to tell her that she was to have this special boy.

(4)现在进行时 现在进行时表示现在正在进行的动作或是现阶段正发生而此刻不一定在进行的动作。
① 现在进行时由“助动词be (am is are ) +现在分词”构成。
② 现在进行时的时间状语有: now, this …, these…等,但经常不用。如:What are you doing up in the tree?(你在树上干什么?)/ I am writing a long novel these days.(我最近在写一本长篇小说)
③ 表示即将发生的动作,一般指近期安排好的事情。常见的动词有:come, go, stay, leave, spend, do等。如:I’m coming now.(我就来)/ What are you doing tomorrow?(你明天干什么?)/ He is leaving soon.(他就要走了)

(5)过去进行时 过去进行时表示过去某一时刻或某阶段正在进行的动作。

⑥在完成时中,一个瞬间性动词(一次性动作)不能与表示一段时间的状语连用,此时须将该瞬间动词改为延续性动词或状态动词。具体变化见下表:

瞬间性动词的完成时 → 延续性动词或状态动词的完成时
have (already) gone to… have been in / at … for (two years)
has come to… has been here since (1990)
(had) left… (had) been away from…
arrived… been in…
died been dead
begun been on
ended been over
bought... had…
borrowed… kept…
joined… been in …
或者使用下面这个句型:
It is / has been + (多久)+ since + 主语(人)+谓语(过去时)+……+过去时间状语
[注意] 在其它的时态中也存在类似问题,记住,关键是:瞬间动词不能和表达一段时间的状语连用。如:How long may I keep the book?(这本书我能借多久?)(句子中keep取代了borrow)
(7) 过去完成时 过去完成时表示过去某一时间或某一动作发生之前已经完成的动作。简言之, 过去完成时所表示的时间是“过去的过去”。
①过去完成时由“助动词had+动词的过去分词”构成。
②过去完成时时间状语有:by (yesterday), by then, by the end of (last…)或者由when,before等引出状语从句。有时句子中会有already, just, once, ever, never等词语,也会有for… 或since…构成的时间状语。如:They had already finished cleaning the classroom when their teacher came.(当老师来的时候他们已经打扫完了教室)/ The woman had left before he realized she was a cheat.(在他发觉那个妇女是个骗子时她已经走掉了)
③过去完成时常用于宾语从句中、after引导的从句中,或者从句是before引导的主句中。如:After I had put on my shoes and hat,I walked into the darkness.(我穿上鞋子戴上帽子走进了黑暗之中)/ He said that he had never seen a kangaroo before.(他说他以前从来没有见过袋鼠)
(8) 过去将来时 过去将来时表示在过去预计将要发生的动作或存在的状态。
①过去将来时由“助动词should(第一人称)或would(第二、三人称)+动词原形”构成。在美国英语中,过去将来时的助动词一律用“would +动词原形”。
②过去将来时常由于宾语从句中,时间状语有:later, soon, the next (day).
③在时间状语从句和条件状语从句中不可以使用过去将来时,而应该使用一般过去时。如:He promised that he would pay me a lot if I helped him with the project.(他答应付给我许多钱如果我帮助他搞那个项目)/ Every time when he was free,he would sit down and read some books.(每次只要他有空他就会坐下来看看书)
④表示纯粹的将来时用would或should,表示打算或主观认为的事情用was/were going to (+动词原形)。如:She told me she would be 18 the next month.(她告诉我她下个月就18岁了)/ She told me that she was going to have a walk with her pet dog.(她告诉我她打算带她的宠物狗去散步)
⑤过去将来时还可以表示一个过去经常性的动作。如:When it rained in the day, he would bring an umbrella with him.(白天下雨时他会随身带一把雨伞)
(9)现在完成进行时:现在完成进行时指一个从过去就开始一直延续到现在并由可能继续下去的动作,它具有现在完成时和现在进行时双重特征,结构是:“have/has + been +动词的现在分词”。如:I have been swimming in the cold water for about two hours.(我已经在冰冷的水里游了将近两个小时)/ How long have you been waiting here?(你在这里一直等了多久?)

Ⅵ 初中英语问题

1. 问题解答: 动词的第三人称单数形式只出现在一般现在时而且主语是第三人称单数的情况下。英语语法规定如果谓语动词使用的动词的单三形式,如果对句子再进行否定、强调或者其他的语法变形,一般都要借助助动词does,使得这个does和后面的动词形成复合谓语,但是复合谓语中只能保留一个助动词,另外一个则应是动词原形形式。这种情况跟情态动词加实义动词原形的情况是一致的。不仅是一般现在时,而且在一般过去时和一般将来时这三种简单时态中,只要使用助动词,那么实义动词充当的谓语动词必须恢复成动词原形形式。

2. 语言知识: 一般现在是是英语中三种简单时态之一,主要用来表示动作或行为在现阶段反复多次出现或发生,也常常用来描写客观事实。在大多数情况下,一般现在时句子的谓语动词使用的是动词原形形式。但是当主语由第三人称主格人称代词he,she,it或者与之语法功能类似的名词充当时,谓语动词词尾则要添加后缀–s或者–es,也就是动词的第三人称单数形式。一般现在时的句子除了主要动词是be动词与复合谓语(情态动词+动词原形)的情况以外,由肯定句变成否定句,由陈述句变成疑问句,由普通句变为强调句,一般都要借助助动词do或者does。但要牢记: 一旦使用助动词do或者does,那么谓语动词则必须恢复成动词原形形式。

3. 典型例句:

① I usually do my homework after dinner. But my sister does not. 我通常在晚饭后做家庭作业。但我妹妹不是这样。

② Does your sister often do her homework before dinner? 你妹妹在晚饭前做家庭作业吗?

③ I don't play football with my classmates very often. 我并不常常和同学踢足球。

④ Yes, that's true. My grandparents do get up very early in the morning. 是的,那是真的。我爷爷奶奶早上的确起床起得很早。

Ⅶ 初中英语语法知识点总结有哪些

一、谓语动词和非谓语动词

从是否能充当句子中的谓语来看,动词有谓语动词和非谓语动词两大类。

1、谓语动词

有人称和数的变化。如:Heisa tractor driver.他是一个拖拉机手。

2、非谓语动词

非谓语动词有动词不定式、动名词和分词三种,在句子里都不能单独作谓语,没有人称和数的变化。如:I am pleasedto meet you.我很高兴与你相识。(动词不定式)

二、实义动词、连系动词、情态动词和助动词

从其含义来分,动词有实义动词(notional verb),连系动词(link verb),情态动词(modal verb)和助动词(auxiliary verb)四类。

1、实义动词

实义动词有完全的词义,并能独立作谓语动词。

如:The sunshonebrightly this morning.

今天早晨阳光灿烂。

2、连系动词

连系动词在句中作谓语动词,后面跟表语。英语连系动词有be(是),seem(似乎),look(看来),keep(保持),become(变成),get(变得),grow(变得),feel(感到),turn(变得,变成),appear(显得),remain(仍旧是)等。

如:Itisnever too late to mend.

改过不嫌晚。

3、情态动词

情态动词有can (能),may (可以,也许),must(必须)等,表示能力、义务、必要、猜测等说话人的语气或情态。情态动词只能和主要动词一起构成谓语动词。

4、助动词

助动词有shall,will,have,be,should,wonld, do等。它们只能和主要动词一起构成各种时态、语态、语气等动词形式,以及否定和疑问等结构中的谓语动词。

三、及物动词和不及物动词

从是否能直接跟宾语来分,实义动词又有及物动词和不及物动词两类。

1、及物动词

后面必须跟宾语意义才完整的实义动词,叫做及物动词(transitive verb)。

如:Ibelievethat the committee willconsiderour suggestion.

我相信委员会将会考虑我们的建议。

2、不及物动词

本身意义完整后面不须跟宾语的实义动词,叫做不及物动词(intransitive verb)。

如:Ithappenedin June 1932.

这件事发生于一九三;年六月。

3、兼作及物动词和不及物动词

英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况:

a) 兼作及物动词和不及物动词时,意义不变。试比较:

Shall I begin at once?我可以立刻开始吗?(begin作不及物动词)

She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词)

b) 兼作及物动词和不及物动词时,有时意义不尽相同。

如:Wash your hands before meals.饭前要洗手。

四、情态动词

在行为动词、连系动词以外,还有两类动词,其中之一就是情态动词。从字面上看,我们就知道这是表示“感情与态度”的动词。

比如:Icando it without much difficulty. (能够,表示自信)

事实上,情态动词的英文说法modal verb,还是值得推敲的。modal,来自于名词mode,和modality(模式,方式)紧密相关,包括likelihood可能性, ability 能力, permission 许可与obligation责任这四种模式。

情态动词自身所具备的意义一般来说也是不完整的,不过和需要涉及其他事物的及物动词不同,情态动词不涉及其他事物,需要的是其他动词,即行为动词和连系动词,来配合使用。

一般来说情态动词是不能用作行为动词的,但也有例外,比如need,既可以用作情态动词,也可以是行为动词,看它的后面跟的是什么。

五、助动词

还有一类动词,也是意义上不完整、需要配合行为动词、连系动词使用的,那就是助动词。顾名思义,助动词就是用来帮助主要动词构成谓语的。

主要包括进行时态的be(is / am / are / was / were)、一般时态的do / does / did,将来时态的will / shall / would / should和完成时态的have / has / had。这种动词的英文名称叫auxiliary verb,简写是v. aux.。
