【#初三# 导语】学习,是每个学生每天都在做的事情,学生们从学习中获得大量的知识,但是,如果问起他们为什么要学习?为谁而学习?估计大多数学生都不知怎么回答,当你问一个高材生为什么让读书时,他也许会说为了不让别人看不起;当你问起一个学习成绩一般的学生,他也许会说为了不被父母责骂,也有可能会说为了不让父母失望;当你问起一个学习成绩不理想的学生,他有可能会说考得好可以得到父母的奖励…… 祝你学习进步!以下是®文档大全网为您整理的《初三上学期英语语法归纳总结》,供大家学习参考。
1.初三上学期英语语法归纳总结 篇一
Climbing up the hill, several boars were seen.
这句子里的现在分词短语(present participial phrase)修饰主语“several boars”是错的;改正方法有二:
(a)确定是逻辑主语,使句子变成“Climbing up the hill, the explorers saw several boars.”
(b)把现在分词短语扩大为副词分句(也称状语从句):“When the explorers climbed up the hill, they saw several boars/ several boars were seen.”
2、垂悬副词短语,如:
After putting a shrimp on the hook, the fish began to bite.
这句的副词短语(adverb phrase)和主语“the fish”有什么逻辑关系呢?真正的'逻辑主语应该是“the fisherman”或“the angler”才对。改正方法和例①同:
(a) After putting a shrimp on the hook, the fisherman found that the fish began to bite.
(b) After the fisherman had put a shrimp on the hook, the fish began to bite.
3、垂悬不定式动词短语,如:
To write well, a lot of practice is needed.
To be a loyal employee, a sense of belonging is a must.
这两个句子的不定式动词短语(infinitive phrases)并不能修饰“practice”和“a sense of belonging”,真正的主语必须是“ 人”,如:
(a) To write well, one needs a lot of practice/a person has to practise a lot.
(b) To be a loyal employee, he or she must have a sense of belonging.
上述三类垂悬结构中,第一类发生的频率,必须注意。但是在下列三种情况下,分词短语是对的,它们并非垂悬结构:
第一,独立结构(The Absolute Construction,见3月7日《中英合谈》)中的分词短语有自己的主语,所以不是垂悬结构。例如:
Such being the case, we can go home now./……it is not wrong to call it a day.
第二,当分词含有介词或连词性质时,它不需要逻辑主语,所以没有垂悬问题存在。例如:
Owing to a lack of funds, the project has to be discontinued.
Provided that there is sufficient time, everyone can do the job better.
第三,当分词短语是用来表示说话者的态度或意见时,也不需要逻辑主语,因此也不存在着垂悬问题。例如:
Judging from his facial look, the news must have been terrible.
Taken as a whole, there is nothing wrong with the logic behind that idea.
2.初三上学期英语语法归纳总结 篇二
冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义。英语中的冠词有三种,一种是定冠词(the Definite Article),另一种是不定冠词(the Indefinite Article),还有一种是零冠词(Zero Article)。
不定冠词a (an)与数词one 同源,是"一个"的意思。a用于辅音音素前,一般读作[e],而an则用于元音音素前,一般读做[en]。
1) 表示"一个",意为one;指某人或某物,意为a certain。
A Mr. Ling is waiting for you. 2) 代表一类人或物。
A knife is a tool for cutting with. Mr. Smith is an engineer.
3) 词组或成语。
a little / a few / a lot / a type of / a pile / a great many / many a / as a rule / in a hurry / in a minute / in a word / in a short while / after a while / have a cold / have a try / keep an eye on / all of a sudden
定冠词的用法
定冠词the与指示代词this,that同源,有"那(这)个"的意思,但较弱,可以和一个名词连用,来表示某个或某些特定的人或东西。
1)特指双方都明白的人或物:Take the medicine. 把药吃了。
2)上文提到过的人或事: He bought a house. I've been to the house.
他买了幢房子。我去过那幢房子。
3)指世上独一物二的事物:the sun, the sky, the moon, the earth
4)单数名词连用表示一类事物,如:the dollar 美元;
the fox 狐狸;或与形容词或分词连用,表示一类人:the rich 富人; the living 生者。
5)用在序数词和形容词级,及形容词only, very, same等前面:
Where do you live? I live on the second floor. 你住在哪?我住在二层。
That's the very thing I've been looking for. 那正是我要找的东西。
3.初三上学期英语语法归纳总结 篇三
(1)形容词作定语一般要放在名词前面,但当形容词修饰不定代词something,nothing,anything时要放在所修饰的不定代词之后。如:something important,nothing serious。
(2)当形容词带有表示度量的词或词组作定语或表语时,定语或表语要后置。如:
We have dug a hole two meters deep.
The hole is about two metres deep.
形容词的比较等级
单音节词和少数双音节词,在词尾加—(e)r,—(e)st来构成比较级和级。其他双音节
词和多音节词,在前面加more,most来构成比较级和级。如:
popular———more popular———most popular
important—more important—most important
副词比较级的构成
(1) 单音节副词和个别双音节副词通过加-er,-est来构成比较级和级。
(2) 绝大多数副词借助more,most来构成比较级和级。
(3) 少数副词的不规则变化:
原级 比较级 级
well —— better —— best
badly —— worse —— worst
much —— more —— most
little —— less —— least
far —— farther —— farthest
farthest furthest
late —— later —— latest
(4) 副词的级前面可以不加定冠词the。
(5) 常用句型有like A better than B和like A(the)best of(in)…
其余变化和形容词类似。
4.初三上学期英语语法归纳总结 篇四
1) 经常性或习惯性的动作,常与表示频腮度的时间状语连用。
时间状语: every?, sometimes, at?, on Sunday
I leave home for school at 7 every morning.
2) 客观真理,客观存在,科学事实。
The earth moves around the sun.
Shanghai lies in the east of China.
3) 表示格言或警句中。
Pride goes before a fall. 骄者必败。
注意:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。 例:Columbus proved that the earth is round..
4) 现在时刻的状态、能力、性格、个性。
I don’t want so much.
Ann Wang writes good English but does not speak well.
比较:Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。
一般过去时的用法
1)在确定的过去时间里所发生的动作或存在的状态。
时间状语有:yesterday, last week, an hour ago, the other day, in 1982等。
Where did you go just now?
2)表示在过去一段时间内,经常性或习惯性的动作。
When I was a child, I often played football in the street.
Whenever the Browns went during their visit, they were given a warm welcome.
3)句型:
It is time for sb. to do sth "到??时间了" "该??了"
It is time sb. did sth. "时间已迟了" "早该??了"
It is time for you to go to bed. 你该睡觉了。
It is time you went to bed. 你早该睡觉了。
would (had) rather sb. did sth. 表示’宁愿某人做某事’
I’d rather you came tomorrow.
4) wish, wonder, think, hope 等用过去时,作试探性的询问、请求、建议等。
I thought you might have some. 我以为你想要一些。
比较:
一般过去时表示的动作或状态都已成为过去,现已不复存在。
Christine was an invalid all her life.
5.初三上学期英语语法归纳总结 篇五
⑴当主语,如:
When to hold the meeting has not yet been decided.
Where to live is a problem.
How to cope with the rising cost of living becomes a daily discussion topic.
⑵当宾语,如:
We must know what to say at a meeting.
He could not tell whom to trust.
Do you know how to play bridge?
⑶当补足语,如:
The problem is where to find the financial aid.
The question is who to elect.
⑷当名词同位语,如:
Tom had no idea which book to read first.
Do you have a rough impression how to do it?
⑸当宾语补足语,如:
Jim is not sure whose to choose.
Mary and John are not certain whether to get married or not.
适用于“疑问词+不定式动词”的动词包括:“know, see, decide, tell, ask, consider, discover, explain, forget, guess, hear, imagine, inquire, learn, remember, think, wonder, understand”等。
有点值得特别注意的是:当这结构当宾语时,它的作用等于名词分句,例如:
I could not decide which dictonary to buy. / I could not decide which dictionary I should buy.
Jack did not know where to find such a good teacher./ Jack did not know where he could find such a good teacher.
有些动词,如“ask, show, tell, advise, inform, teach”等,可以先有个宾语,然后才接着加上适当的“疑问词+不定式动词” 结构。例如:
The chief technician showed the apprentice how to repair the machine.
Have you told him where to get the application form?
