中考初中英语if条件句讲解及练习

【知识要点】

定义：常见的if条件状语从句表示在某条件下，某事很可能发生，条件是可能存在的，主句中某种情况发生的概率也是很高的。

E.g. If you ask him，he will help you．

如果你请他帮忙，他会帮你的。

E.g. If you fail in the exam，you will let him down．

如果你考试不及格，你会让他失望的。

E.g. If you have finished the homework，you can go home．

如果你作业做完了就可以回家了。

另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设。从句多用一般过去时或过去完成时，表示对现在或过去的一种假设。

E.g.If I were you，I would invite him to the party．

如果我是你，我会邀请他参加聚会。

E.g.I would have arrived much earlier if I had not been caught in the traffic．

要不是交通堵塞，我本会来得早一些。

另外你还要注意if 条件句的时态搭配

1．if从句用一般现在时，主句用一般将来时

E.g. If he runs he’ll get there in time.

如果他用跑的，他就会及时赶到那儿。

E.g. The cat will scratch you if you pull her tail.

如果你拉猫的尾巴，它就会抓你。

2．if从句用一般现在时，主句用may/might/can

E.g. If the fog gets thicker the plane may/might be diverted.

如果雾在大一些，飞机可能就会改在别的机场降落。

E.g. If it stops snowing we can go out.

如果雪停了，我们就可以出去。

3．if从句用一般现在时，主句用must/should

E.g. If you want to lose weight you must/should eat less bread.

如果你想减肥，你必须少吃面包。

4．if从句用一般现在时，主句用一般现在时

E.g. If you heat ice it turns to water. (也可用will turn)

如果把冰加热，它就会化成水。

5．if从句用现在进行时，主句用一般将来时

E.g. If you are looking for Peter you’ll find him upstairs.

如果你是在找彼得，上楼就会找到他。

6．if从句用现在完成时，主句用一般将来时

E.g. If you have finished dinner I’ll ask the waiter for the bill.

如果你吃完了，我就叫服务生来算账

注意：

学习" if " 引导的条件状语从句的用法,现在总结一下:

if 条件句不一般,几个要点记心间;

条件句,放在前,逗号要放句中间。

条件句表可能，主句多用将来时；

条件句表事实，主句常用现在时。

在if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。如：

E.g. We can walk there if we can't find a bus .

E.g. If it rains tomorrow ,we will not go to the zoo.

E.g. What will you do if you find a panda in danger.

如果if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。

E.g. If bears are in danger ,they attack people.

在if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若if 条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则

3．阅读理解

He was an old man who fished alone in a small boat on the sea and he had gone eighty-four days now without

taking a fish. In the first forty days a boy had been with him. But after forty days without a fish, the boy's parents had told him that the old man was now salao, which was the worst form of unluck, and the boy had gone with another boat which caught three good fish the first week. It made the boy sad to see the old man come in each day with his boat empty. The sail looked like the flag of failure forever.

The old man was thin with deep wrinkles(皱纹)in the back of his neck. His face was terribly brown because of the strong sunlight on the sea every day and his hands had the deep scars(伤疤)from dealing with heavy fish on the lines. But none of these were fresh. Everything about him was old except his eyes and they were the same colour as the sea and were cheerful.

"Santiago," the boy said to him as they climbed the bank from the sea. "I could go with you again. We've made some money."

The old man had taught the boy to fish and the boy loved him.

"No, "the old man said." You're with a lucky boat. Stay with them."

"But remember how you went eighty-seven days without fish and then we caught big ones every day for three weeks."

"I remember," the old man said.

"It was papa who made me leave. I am a boy and I must follow him."

"I know," the old man said. "It is quite normal."

"He hasn't much faith(信心)."

"No," the old man said." But we have. Haven't we?"

"Yes," the boy said. "Can I offer you a beer on the Terrace?"

"Why not?" the old man said. "Between fishermen."

（1）In the story the old man was the boy's .

A. grandfather

B. friend

C. boss

D. host

（2）The word "they" in Paragraph 2 refers to of the old man.

A. the hands

B. the scars

C. the eyes

D. the wrinkles

（3）The old man refused the boy to go fishing with him again because .

A. he wanted to fish by himself

B. he could really understand his parents

C. the boy asked for some money

D. the boy had already learnt how to fish

（4）From the story we can know that .

A. the old man was always full of hope

B. the boy's parents believed in the old man

C. everyone laughed at the old man's bad luck

D. the boy was worried about the old man's health

【答案】（1）B

（2）C

（3）B

（4）A

【解析】【分析】主要讲了一个老人84天没有捕到鱼了，男孩的父母不让小男孩和老人一起捕鱼，认为老人运气不好，老人比较理解男孩的父母。

（1）细节题。根据全文可知小男孩和老人一起去捕鱼，他们的关系是朋友关系，故选B。

（2）细节题。根据Everything about him was old except his eyes除了他的眼睛，他周围的一切都很老，所以they代指眼睛，即eyes，故选C。

（3）细节题。根据"It was papa who made me leave. I am a boy and I must follow him." "I know," the old man said. "It is quite normal."可知老人理解男孩爷爷的想法，所以拒绝小男孩再次和他一起去捕鱼，故选B。（4）细节题。根据"He hasn't much faith(信心)." "No," the old man said." But we have. Haven't we?"可知男孩爷爷对老人没有信心，但是老人和男孩有信心，故选A。

【点评】考查阅读理解，主要考查细节题，注意从文中仔细寻找答案。

4．阅读理解

It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to sneeze and later you may cough. You must have a cold！Wait a moment. Could it just be a common cold or the flu(流感)that's been going around？

A cold gives you a runny nose and cough. But it's usually easy to deal with. Some people take medicine while others drink herbal tea or chicken soup. Usually you feel better after a week.

On the other hand, the flu can be much more dangerous. It usually gives you fever. Sometimes it can cause death. According to an American magazine, the worst flu killed about 50 million people from 1918 to 1919.

Don't worry. If you get a flu vaccine(疫苗), it can stop you from getting the virus(病毒).Flu vaccines work by giving the body a small number of flu viruses. This causes your body to develop antibodies(抗体). So next time you get the flu, the antibodies will help you.

The flu virus changes every few years. Therefore, there are so many types of flu, such as HlN1 and H5N1.The antibodies for one type of flu can't help us against all types of flu. That's why we need to get the vaccine every year.

However, good healthy habits may also help stop you developing a cold or flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help you strengthen(增强)your immune system(免疫系统).

（1）If you have a common cold, usually you'll feel better after .

A. a week

B. two weeks

C. ten days

D. twenty days

（2）According to the passage, which is TRUE of the flu？

A. It first happened in 1919.

B. It usually doesn't give you fever.

C. It is easy to deal with.

D. It can kill people sometimes.

(完整)初中英语感叹句讲解

感叹句结构及用法 感叹句一般是用来表示说话时的喜悦、惊讶等情感。英语感叹句常用"what"和"how"引导，"what"和"how"与所修饰的词置于句首，其它部分用陈述句语序。 一、由"what"引导的感叹句： "what"意为"多么"用作定语，修饰名词（被强调部分），单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是： what+(a/an)+adj.+n.+主语+谓语. 如： ① What a clever girl she is! 多么聪明的姑娘呀！ ③ What good children they are! 他们是多么好的孩子呀！ ⑤ What delicious food it is! 多么有味的食物呀！ 二、由"how"引导的感叹句： "how"意为"多么"，用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词，这类句子的结构形式是： How+adj.（adv.）+主语+谓语. 如： ① How cold it is today! 今天多么冷呀！ ② How nice the pictures are! 多么漂亮的图画呀！ ③ How happy they look! 他们显得多么高兴呀！ 三、在表示同一意义时，英语感叹既可用"what"引导，也可用"how"引导。如： ① What a hot day it is! How hot the day is ! 多么热的天气呀！ ② What tall buildings they are! How tall the buildings are! 多么高的楼房呀！ 四、感叹句在表示激动强烈的感情时，口语中常常采用省略句，其后面的主语和谓语往往略 去不讲。 如： ① What a fine day! 多么晴朗的天呀！ ② What an honest boy! 多么诚实的孩子呀！ ③ What red apples! 多么红的苹果呀！

初中英语感叹句用法及练习题附答案

感叹句 感叹句是表达喜、怒、哀、乐以及惊奇、惊讶等强烈感情的句子。感叹句通常由what 或 how 引导。"what"和"how"与所修饰的词置于句首，其它部分用陈述句语序。 一、由"what"引导的感叹句："what"意为"多么"用作定语，修饰名词（被强调部分），单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是： what+(a/an)+adj.+n.+主语+谓语. 如：① What a clever girl she is! 多么聪明的姑娘呀！ ② What an interesting story it is! 多么有趣的故事呀！ ③ What good children they are! 他们是多么好的孩子呀！ ④ What beautiful flowers they are! 多么漂亮的花呀！ ⑤ What delicious food it is! 多么有味的食物呀！ ⑥ What heavy snow it is! 多么大的雪呀！ 二、由"how"引导的感叹句："how"意为"多么"，用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词，这类句子的结构形式是：How+adj.（adv.）+主语+谓语. 如：① How cold it is today! 今天多么冷呀！ ② How nice the pictures ar e! 多么漂亮的图画呀！ ③ How happy they look! 他们显得多么高兴呀！ ④ How well she sings! 她唱得多好呀！ ⑤ How hard they are working now! 他们干得多么起劲呀！ 三、在表示同一意义时，英语感叹既可用"what"引导，也可用"how"引导。如：① What a hot day it is! How hot the day is ! 多么热的天气呀！ ② What tall buildings they are!

初中英语条件句“过三关”知识精讲

初中英语条件句“过三关”知识精讲 [一号档案]基本用法关 if意为“如果”，是连词，用来引导条件状语从句。由if引导的条件状语从句，既可位于主句之前，也可位于主句之后。当从句在前时，必须用一个逗号与主句隔开。如：如果你不小心，车子会撞到你。 A car may hit you if you are not careful. 主句从句 If you are not careful, a car may hit you. 从句主句 [二号档案]时态关 在该句型中：（1）当主句是一般将来时，（2）当主句的谓语含有情态动词时，（3）当主句的谓语含有want, wish, hope等动词时，（4）当主句是祈使句时，与其连用的条件状语从句的谓语动词通常用一般现在时代替一般将来时。如： 如果他明天不能准时来，我们就不知道应该怎么办。 If he won’t come on time tomorrow, we won’t know what to do. (×) If he doesn’t come on time tomorrow, we won’t know what to do. (√) [三号档案]句型转换关 对条件状语从句同义句转换的途径有： （1）借助“祈使句+and/ or+句子（谓语通常用将来时态）”这一句型来转换。其中，and 表示句意顺承；or表示句意转折，意为“否则”。如： If you work hard, you’ll pass the exam easily. =Work hard, and you’ll pass the exam easily. =Work hard, or you won’t pass the exam easily. （2）借助介词with或without来转换条件状语从句。如： If there is no water, the fish may die. =Fish may die without water. If you help me, I’ll finish the work soon. =With your help/ With the help of you, I’ll finish the work soon. （3）借助动词不定式短语来转换。如： It will be a pity to leave him alone at home. = It will be a pity if we leave him alone at home.

最新中考初中英语条件状语从句分析(全,含练习及答案)

中考初中英语条件状语从句分析（全，含练习及答案） 本节课我们学习其中的条件状语从句。 目录： 一、概念； 二、时态； 三、条件状语从句的引导词； （一）if 引导的条件状语从句； （二）unless引导的条件状语从句； （三）as /so long as引导的条件状语从句； （四）once引导的条件状语从句； 四、条件状语在句中的位置； 五、转换； 六、拓展； 七、综合练习； 一、概念 在某种条件下，可能发生某事。由if/unless等引导的表示条件的句子，就叫条件状语从句。 e.g: If you put wood into water, it floats. 如果你把木头放到水里，它就会浮起来。 Unless you keep ice cream in a fridge, it melts. 除非你把冰淇淋放进冰箱，不然它就会融化。 二、时态 1．当主句和从句所表示的是原理、客观真理、规则时，主句是一般现在时

（包括祈使句和含有情态动词can/may/must等），从句也要用一般现在时。 例如： 1) If you put a piece of paper into water, it gets wet．如果你把一张纸放进水中，它会变湿。(原理) 2)Be careful if you cross the road.(祈使句) 3) You must see the doctor if you are ill.( 含有情态动词） 2. 在if条件状语从句中，如果从句谈论的是一个可能发生的事实及其产生的相关结果，主句用一般将来时，从句用一般现在时。 e.g: 1) If it rains tomorrow, we will not go to the zoo. 2) If you go to bed earlier, you won't feel tired in the morning. 3. 如果从句用现在进行时或现在完成时，主句需用一般将来时。 1）If you are looking for Peter you’ll find him upstairs. 如果你是在找彼得，上楼就会找到他。 2）If you have finished dinner I’ll ask the waiter for the bill. 如果你吃完了，我就叫服务生来算账。 三、条件状语从句的引导词 （一）if 引导的条件状语从句 引导条件状语从句最常用的连词是if，常见的if条件状语从句表示在某条件下，某事很可能发生，条件是可能存在的，主句中某种情况发生的概率也是很高的。 如： If you ask him，he will help you．如果你请他帮忙，他会帮你的。 If you fail in the exam，you will let him down． 如果你考试不及格，你会让他失望的。 If you have finished the homework，you can go home． 如果你作业做完了就可以回家了。 另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设。从句多用一般过去时或过去完成时，表示对现在或过去的一种假设。 如：

全国优秀畅销书，薄冰、张道真系列语法图书销售突破220万册！ 丨学英语，凭什么让我学语法吗？？？ 不时听到一些青年问道：学英语一定要学语法吗？语法应该怎么学呢？我们 就这两个问题简单地谈一点个人意见。 对中国学生来说，尤其是成年人，我看是学点语法好。语法，顾名思义，乃是语 言的法则和规律。学习语法，尤其是一些基本法则，至少有下列几个好处： 第一 可以使你学得快些，因为已有现成的前人总结的法则，用不着你从 头摸索。 第二 可以使你学得透些，因为通过语法对语言现象不仅可以知其然，而 且可以知其所以然。 第三 可以使你学得准些，因为语法法则就是一条条准绳，可以用以衡量 一句话是否正确。 第四 语法不但可以引你入门，更可以引你入胜，使你逐渐眼界开阔，语感加深，从而使你的英语水平不断提高。 丨那么应该如何学习语法呢？ 我认为在学习语法过程中，应该注意下面几点： 第一 基本概念最重要。在学习每个语法项目时，一定要把它的基本概念 搞清，牢记在心。 第二 要大量地实践，大量地练习。实践要包括听、说、读、写四个方面， 练习要着重说和写。 第三 学习语法时，应多用比较法。如对动词时态、冠词、介词、名词的 单、复数等较难的语法项目进行相互比较，效果就比较好。 第四 要将语法法则与习惯用法分开。碰到习惯用法，就不必钻牛角尖， 进行徒劳的分析。而习惯用法在英语中则是大量地存在着的。 第五 将一本语法书通读一遍，当然也不无好处。但最好将它作为工具书， 像词典一样地经常查阅，始能学得比较细致牢靠。 第六 实用英语语法只应是入门的向导，像一根拐棍一样。英语达到一定 水平之后，就应将它扔掉。起码不要让许多语法条条充斥头脑，影响你说和写的 流利性。 最后 可能还会有人说，语法应该学，就是太枯燥。我的感觉是：开头有 点枯燥，过些时候，就会像嚼橄榄似的，越学越有味了。如若不信，请试试看。
