『贰』 英语高一 主语从句

主语从句

一、概述:在句子中起名词作用的各种从句统称为名词性从句。根据它们在句中的语法作用,这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。
二、 几个共性问题:
1.连接方式
(1) 在由连词that, whether, if引导的名词性从句中,引导词在句中不做成分,在宾语从句和表语从句中,that可以省略。
(2) 在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中,其连接代词在句中起名词性作用,担当一定成分。
(3)在由连接副词when, where, why, how引导的名词性从句中,其连接副词在句中作状语。
2.whether和if的区别
(1)whether在引导的主语从句中可以置于句首,而if则不能。
(2)whether可以与or not连用,or not可以紧跟在whether之后,也可以置于从句末尾;if一般不能和or not连用。
(3)表语从句、同位语从句和介词宾语从句(即在系词be和介词之后),只能用whether连接,而不用if。
(4)从句是否定式时,一般用if, whether很少用在否定式从句中。
例如:I don’t care if he doesn’t come . 如果他不来,我也不介意。
The problem is whether we can carry out the plan.
问题是我们是否能实施这项计划。

三、 主语从句
1.主语从句主要有三类:
(1) 由连词that引导的主语从句。
例如:That you will win the medal seems unlikely.
你想获得奖牌看起来是不可能的。
That you are so indifferent bothers me.
你如此冷淡使我很烦恼。
That she survived the accident is a miracle.
她在事故中幸免于难简直是奇迹。
(2) 用连接代词或连接副词if, whether 引导的主语从句。
例如: Which of them escaped from the prison is still a mystery.
他们哪一个是从监狱里逃跑的,仍然是个谜。
When they will come hasn’t been made pubic.
他们什么时候来还不知道。
Whether she is coming or not doesn’t matter too much.
她来不来都无关紧要。
(3) 用关系代词引导的主语从句。
例如:What you need is more practice.
你所需要的是更多的训练。
What I want to know is this. 我想知道的就是这事。
Whatever we do is to serve the people.
我们无论做什么都是为人民服务。
主语从句可以直接放在主语位置上,也可以用it作形式主语,
而将从句放在句末(尤其是当谓语较短时)。
例如:That light travels in straight lines is known to all.
光沿直线传播,这是众所周知的事。
=It is known to all that light travels in straight lines.

英语句子成分分析

句子是按照一定的语法规律组成的,表达一个完整的意义。一个句子一般由两部分构成,即主语部分和谓语部分,这两部分也叫做句子的主要成分。句子的次要成分包括宾语,定语,状语,表语等。句子成分是句子中起一定功用的组成部分。

1)主语:是一句的主体,是全句述说的对象,常用名词,数词或代词担任,一般放于句首。如:

Students study. (学生学习。)

We are friends.(我们是朋友)

这两句话中单词students是个名词,we是代词,它们在句中做主语。

2)谓语:是对主语加以陈述,表示主语的行为或状态,常用动词或者动词词组担任,放在主语的后面。如:

Students study. (学生学习。)

We are friends. (我们是朋友)

这两句话中单词study和are都是动词,study叫做实意动词,are叫做be动词,它们在句中作谓语。

3)宾语:表示行为的对象,常由名词或者代词担任。放在及物动词或者介词之后。如:

They are teachers. ( 他们是老师。)

I play with him. (我和他一起玩。)

这两句话中单词teachers是名词,单词him是带词,它们在句中作宾语。

4)定语:是用来说明或者限制名词的成分,常用形容词或者相当于形容词的短语或从句担任。形容词放在名词之前,相当于形容词的短语或从句放在名词的后面。如:

This is a red sun.(这是个红太阳.)

He is a tall boy.(他是个高个子男孩。)

这两句话中单词red和 tall都是形容词,它们作定语。

5)状语是用来说明动词,形容词,副词或整个句子的成分。常由副词担任。修饰动词时可以放在动词之前,也可以放在动词之后;修饰形容词或副词时放在它们之前。如:

The students study hard. (这些学生学习努力。)

I often write to him. (我常给他写信。)

The bag is too heavy. (这个书包太重了。)

这三句话中单词hard 和often修饰的都是动词,第三句话中单词too修饰的是形容词,它们都作状语。

6)表语:用来说明主语的性质或状态。一般由名词或者形容词担任。如:This table is long. (这个桌子是长的。)

通常情况下,主语和宾语前的成分是定语,谓语前的成分是状语,时间词作状语放在句子后面。句子的成分分布如下:

(定语) 主语 (状语) 谓语 (定语) 宾语 (状语)

如:(The tall) boy (often) go (to the big) zoo.

(The happy) child --- went (his) home yesterday.

请分析下面句子的结构说出各个成分

1)I have two elder sisters. (我有两个姐姐。)

2) They don't swim very well.(他们游泳不太好。)

3) Do you go to school every day (你每天去上学吗?)

4) I really want a cup of tea.(我真的想要一杯茶。)

5) Miss Smith teaches English very well.(史密斯先生教英语非常好。)

语法其实并没有一些人想象的那么可怕,其实里面有很多趣味。

第一讲 英语句子成分

WARM-UP:1)The teacher in the classroom. 2)Sang many songs and danced happily. 3)She attracts. 4)Many people living in the country. 5)All the books on the desk over there.

以上这些形式都不能构成英语句子。

英语句子(sentence)=主语+谓语(核心:主动词)

5、定语:
(1) 修饰名词或代词的成分,常由形容词、名词(含所有格)、代词(物主、指示、疑问、不定)、介词短语、不定式(短语)充当,在初三阶段还学习了定语从句做定语的知识。如:Put it in the top drawer.(把它放在最上层的抽屉里。) / France and Switzerland are European countries.

(4) 介词短语修饰名词时只能放在名词的后面:The monkey in the cage was caught yesterday. (笼子里的猴子是昨天逮着的。)

(5) 形容词修饰复合不定代词时,往往后置。如:He remembered everything unusual. (他记得所有不寻常的事情。)

(6) 定语还可以用从句充当,详见 定语从句。

(7) 注意:由于定语属于修饰性的成分,因此它常归入主语、宾语、表语之中,不作为句子的主要成分。

6、状语:
(1) 说明动作“何时”、“何地”、“如何”发生,或者说明形容词或副词的程度,一般由副词、介词短语、不定式、状语从句等充当。如:I was not born yesterday.(我又不是昨天才出世的娃娃。)/ For many of these families a college ecation was something new.(对其中的许多家庭来说,大学教育是件新事物。)/ He woke up to find his house on fire.(他醒来发现房子着火了。) / You cannot leave until your work is finished.(在你的工作被完成以前你不能离开)

(4) 状语还可以用从句来充当,有时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、比较状语从句、让步状语从句、条件状语从句等。详见“状语从句”。

(5) 注意:由于状语属于修饰性的成分,常归入谓语,因此不作为句子的主要成分。

7、宾语补足语:
(1) 补充说明宾语的动作、状态的成分为宾语补足语,常由名词、形容词、动词非谓语形式(不定式、现在分词、过去分词等)、介词短语等充当。如:Call him Jim, please. (请叫他Jim。) / I tried my best to make him happy. (我竭尽所能让他开心。) / Ask her to come to dinner tomorrow. (请他明天来。) / He let the smaller animals bring food to him. (他让小动物们给他带食物来。)

『伍』 高中英语主语从句

若选择that,就成来了it做形式主语自that引导主语从句,that从句里面应该是陈述句,语序就应该如同你说的:the medicine will bring about side effect。而并非题干里面的语序。意思就成了“这种药会带来副作用这还不确定。”
而本题目所想表达的意思是“这种药会带来什么样的副作用这是不确定的。”所以说,选择what。

『陆』 英语必修三第四单元Astronomy:the science of the stars的原文 急!!!在线等!!

HOW LIFE BEGAN ON THE EARTH
No one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a "Big Bang" that threw matter in all directions.After that, atoms began to form and combine to create stars and other bodies.

For several billion years after the "Big Bang", the earth was still just a cloud of st. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when
the st settled into a solid globe. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in
time to proce carbon, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even more important is that as the earth cooled down, water
began to appear on its surface.
Water had also appeared on other planets like Mars but, unlike the earth, it had disappeared later. It was not immediately obvious that water was to be fundamental to the development of life. What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas. This proced a chain reaction, which made it possible for life to develop.
Many millions of years later, the first extremely small plants began to appear on the surface of the water. They multiplied and filled the oceans and seas with oxygen, which encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow on land. They were followed in time by land animals. Some were insects. Others, called amphibians, were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared for the first time. They proced young enerally by laying eggs. After that, some huge animals, called dinosaurs, developed. They laid eggs too and existed on the earth for more than 140 million years. However,
65 million years ago the age of the dinosaurs ended. Why they suddenly disappeared still remains a mystery. This disappearance made possible the rise of mammals on the earth. These animals were different from all life forms in the past, because they gave birth to young baby animals and proced milk to feed them.
Finally about 2.6 million years ago some small clever animals, now with hands and feet, appeared and spread all over the earth. Thus they have, in their turn, become the most important animals on the planet. But they are not looking after the earth very well. They are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space. As a result of this, many scientists believe the earth may become too hot to live on. So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.

亚洲的沙尘暴
几百年以来,沙尘暴一直是许多亚洲国家面临的主要灾难.科学家尝试过多种方法解决这个问题,在中国,也发动了群众运动来对付沙尘暴.
沙尘暴是夹带沙尘的强烈而干燥的风.沙尘暴夹带的沙尘含量常常很大,以致于可以遮天蔽日.风力强大时可以搬动沙丘.世界上沙尘暴发生的四个主要地区是中亚、北美、中非和澳大利亚.来自内蒙的任建波是这样来描述他小时候遭遇的一次沙尘暴的:
“遇上沙尘暴是一种可怕的经历,”他说,“你一点办法也没有.那是我遭遇过的最可怕、最危险的境况.你只能祈求会活下来.那时候我觉得我会消失在沙尘下.”
中国的西北地区是中亚沙尘暴中心的一部分.沙尘暴发端于沙漠地区.因“荒漠化”越发严重,中国近年来发生沙尘暴的次数明显增加了.这是由于气候变化和人们伐树挖草,使土地变成荒漠后产生的一种作用.
沙尘暴有时候会影响北京.居民醒来时,看到昏黄的天空,狂风夹着黄沙在城里肆虐.暴风有时持续一整天,车辆开得很慢,因为浓浓的尘埃降低了能见度.
中国中央气象站能在沙尘暴到达北京前几周预报沙尘暴,但沙尘暴的力量有时很惊人.沙尘暴到来时,气象专家建议人们不要外出.家住北京的黄小梅说:“在沙尘暴中骑车真可怕.风力很强,呼吸困难,沙尘使人难受.所以不要出门,最好带上口罩.”
沙漠离北京西境只有250公里.为阻止沙漠的逼近,政府已经开始植树.政府已经种了300亿棵树,并准备在未来的五年里继续种植.

祝你开心如意!
