英语作为主科之一,上了中学之后的学习任务更加繁重,那么2024中考英语知识点归纳总结有哪些呢?以下是小编准备的一些2024中考英语知识点归纳总结,仅供参考。
一、一定要背诵单词
初中英语的学习历来都是把单词看作是重点的。如果将英语比作为一座摩天大楼的话,那么同学们所学习的单词就是建筑这座大楼所需要的砖瓦,如果没有砖瓦这些基础的话,同学们是怎样才能够建筑出一栋大楼呢。所以同学们一定要能够拥有足够多的“建筑材料”。单词是基础,所以同学们要多学习,多记忆,多背诵单词。
二、学好英语语法
在学习初中英语的语法时候,要细心琢磨语言规则的含义、用法特征,然后进行归纳总结,通过典型例句来理解。比如,我们在学习时态的时候,以动词的时态表示的时间为线索,把现在进行时与过去进行时,现在完成时与过去完成时等相关的时态结合起来学,掌握这些时态表述的时间和动词形式变化上的共同特点,利用它们的“锁链”关系,理解和掌握各种时态的用法。
三、多做阅读训练
初中生要想学好英语一定要提高自己的阅读能力,提高阅读能力的最有效办法是进行广泛的课外阅读,选择不同文体和不同题材文章,培养自己的语感和良好的阅读习惯,丰富知识。制定切实可行的阅读计划,每天或每周几天都要坚持不懈地进行课外阅读。
三、学习英语要灵活运用
学好英语要记单词、学短语、句型要结合具体语境,不要脱离上下文孤立地死记硬背。碰到不熟悉的用法要勤于思考并不断的积累。初中生都要明白,那些英语成绩好的学生开始学英语的时候,也会出现很多的错误,但他们知道如何纠正自己的错误。大家都是可以做到,只要把错误改过去,就自然会变成自己的知识。

Rachel felt sad as she walked to the school bus stop. Her neighborhood looked like a junkyard. There was a lot of rubbish on the road. The front door to Lee‘s Grocery was covered with ugly graffiti(涂鸦).
Yuck! Rachel said as she brought her foot back to kick (踢) an empty bottle off. Then she changed her mind, picked the bottle up and threw it into a rubbish basket on the corner. She hurried to meet her friends at the bus stop.
Mr Lee felt sad as he looked out of his grocery store window. Hmph, he said as the girl passed by. She‘s perhaps another troublemaker, he thought. One of those kids painted graffiti all over my door. Kids today are just no good. What the girl did next, though, surprised him. She picked up the bottle and dropped it into a rubbish basket.
That‘s a switch, thought Mr Lee. All morning he kept picturing that girl. At noon, when he walked to the corner to mail a letter, he saw the rubbish that was in front of his store. He thought of that girl again, then got a broom and started sweeping(打扫) the walk.

Do you get angry when someone stands too close to you or talks too loudly?
Many of us do. What makes us feel uncomfortable about these people? Perhaps it‘s about
personal space.
Some scientists say that humans need a distance between themselves and strangers.

Manypeople hold newspapers in front of them on the subway. Perhaps they are using the newspaper to separate (分离) themselves from other people.

Few people knew his name or his face. But when he came back to the earth after a 21-hour trip to space, Yang Liwei’s smile was seen across the world.
The 38-year-old astronaut was sent into space at 9:00 a.m. October 15, 2003 by China’s Shenzhou V spaceship, and it traveled around the earth 14 times. He landed safely at 6:23 a.m. the next day. So China became the third country to successfully send a person into space, after the former Soviet Union(前苏联) and the U.S.A.
Yang was pleased with his job. “I think ours was one of the most successful,” he said.

He has spent five years training to become a spaceman after 1350 hours’ flying in the air. Although it was hard work, Yang loved it. Yang’s success was well worth all the hard work. Yang has become China’s first spaceman.

It’s hard to imagine that just 25 years ago, Berlin was a city split (分开) into two by the Berlin Wall. I’ll never forget how people were excited as the Berlin Wall came down in 19__. Since then, Berlin has become one of the coolest cities in Europe. Here are the main reasons why I think Berlin is cool.
It’s affordable. Berlin has cheap hotels and everyday objects. You don’t have to worry about spending too much money when visiting Berlin.
It has fantastic festivals. Berlin knows how to give parties, and there is a festival here every month of the year. Perhaps the most famous is the Berlin International Film Festival.
It has great architecture (建筑设计). Berlin has beautiful architecture of its own. The Brandenburg Gate, built in the 18th century, is one of the city’s most famous buildings, symbolizing more than 200 years of history. The TV Tower is as good as the Eiffel Tower in Paris and the London Eye.
The art scene is flourishing (繁荣). Berlin is a city of living art. Artists are allowed to create works of art on the sides of buildings.
If you want to visit an affordable European city with culture and lots of colors, Berlin is the place to be. What are you waiting for? Get to Europe’s coolest city before everyone else discovers it.

Without a man, there would be no “happiest place on earth”, also known as Disneyland. That man was Walt Disney.
Disney was born in 1901 in Chicago, Illinois. As a child, he enjoyed drawing and even sold his pictures to his neighbors. In 1918, Disney joined the Red Cross and drove an ambulance (救护车) in France during World War I (第一次世界大战). After the war ended, Disney started making short cartoons in Kansas City, but soon he used up all his money. He decided to get a job in Hollywood. He went to California with only $20 with him.
It took a while, but Disney began to enjoy success with his cartoons. He created Mickey Mouse, the most famous cartoon character ever. Then in 1937, Snow White and the Seven Dwarfs came out and it was a huge success. During the following years, Disney made many more movies that we still watch today, including Pinocchio, Dumbo, and Bambi.
In the 1940s, Disney had an idea of building a fun park for families and the idea grew bigger and bigger ... Years after Disney first had the idea, the first Disneyland opened in 1955 in Anaheim, California. At that time, the ticket cost a dollar. By 1965, 50 million visitors had visited Disneyland.
Disney died in 1966, 5 years before the opening of his next dream park, Disney World in Lake Buena Vista, Florida.
If you ever visit one of the Disney parks, or go to a Disney movie, think of the man who started it all.

三、阅读理解(共5小题,每小题2分,计10分)
Every 30 seconds there is an earthquake. But don't worry because most are so weak that they cannot be. felt. Only a few big ones hurt people.
Many earthquakes happened in China, such as the big one in Sichuan last month. Thousands of people died in it. So it's important to know what to do when one hits. Here are some tips on how to stay safe in an earthquake.
1. If you are indoors during an earthquake, hide (躲藏) under a desk. Stay away from windows and anything that could fall on you.
2. If you are outdoors, move to a clear place. Try to be away from trees, signs, buildings and streetlights. These could fall on you.
3. If you are in a shop and far from the door, don't try to run outside and rush for exits (出口). Everyone will be doing that and you'11 find it hard getting out. Don't get into a lift during an earthquake. Just hide under some strong cover near you.
4. When an earthquake has ended, be careful because aftershocks may still happen. These are just as dangerous as the earthquake itself. So stay under the desk until you make sure it's safe to get up.
5. If you are at home and you smell gas (煤气) , open the windows and get out of the building as quickly as you can. A gas line in your house may be broken. This could be very dangerous.

学习要养成归纳的习惯,这也是学习任何知识的重要方法,那么九年级上册英语第九单元知识点怎么学习呢?以下是小编准备的一些九年级上册英语第九单元知识点,仅供参考。
记单词有窍门
单词是英语学习的基础,它是垒起英语这座长城的坚硬的.基石。初三复习阶段,单词的记忆是非常重要的。下面,笔者为大家介绍一些巧记单词的方法。
选择最佳记忆时间
每一个同学都有不同的记忆习惯和最佳记忆时间,通过实践摸索,同学们可以选择自己记忆效果最佳的时间。如每天清晨或每晚临睡以前,坚持每天背单词的习惯。
运用单词本身的规律
记单词时,我们应该结合单词的构词法、词性转换或同义词、反义词的归纳来巧记单词。如:care(n./V.)-careful(adj.)-careless(adj.)-carefully(adv.)-carelessly(adv.)-carefulness(n.)-care鄄lessness(n.)
利用多种感官记忆
同学们在背单词时,常常是读读写写,边读边背。事实上,利用听觉来加强记忆也能起到很好的效果。如把单词的读音、拼写和汉语词义录在录音机里,在临睡前或上下学的路上反复听,它能刺激我们的无意注意,强化记忆,轻轻松松就记住了单词。
通过归类记忆
在记忆单词时,同学们还可以有目的地进行单词整理,如把单词归类,写在小卡片上,利用平时空闲的时间进行专项的单词记忆。如体育项目类:
high-jump(跳高),long-jump(跳远),discus-throwing(掷铁饼),relay-race(接力跑),110-meterhurdles(110米跨栏),diving(跳水),fencing(击剑),boxing(拳击),tabletennis(乒乓球),tennis(网球),badminton(羽毛球),volleyball(排球),football(足球),basketball(篮球),gymnastics
(体操)等。
遵循记忆规律
在背单词的过程中,很多同学都有这样的经历,明明自己背过的单词不久以后却又忘了。这就需要我们遵循记忆规律,经常循环地复习。通常,以每两周进行一次单词总复习为宜。

八年级学生在这个阶段,英语学习更需要方法技巧引导。下面是为大家整理的如何教八年级学生英语,喜欢可以收藏分享。
进入新课改阶段后,八年级英语该怎么教就难住了很多老师。为激发学生学习英语的积极性,将英语编成好记的童谣是一些老师的绝招,让学生在玩中,不知不觉就掌握了学习英语的方法。
在一场初中英语教学研讨会上,一位英语教师洪伟展示了上英语课的经验,这位老师用游戏上英语课,将学生要学的英语单词编成有趣且容易记的童谣,让学生边说边做动作,这样上课的学生们就能在游戏中学习英语,并且对英语产生了浓厚的兴趣。教孩子学习英语还可以通过使用成语、绕口令、笑话、诗歌等辅助。
教师想要教好教材,要做很多事情。首先是理解新教材,只有对新教材融会贯通,才能在教学的时候更好教导学生。其次可以和家长联络,希望家长可以给学生创造英语学习的环境,让学生在家里也能多运用英语,这样学生才有获得感,有助于形成师生之间教与学的良性互动。
很多一线英语教师都在苦恼如何教学生英语,其实可以采用集体备课的办法,一起讨论英语课讲什么,怎么讲,讲的程度如何。这样集体备课,大家的学习进度不会过快过慢,也能集思广益,发现更多优秀的教学方法。
教师还可以将初中阶段要掌握的单词制作成单词条,在讲新内容的同时,把旧单词融入其中,让学生用“以新带旧”的方法记单词。
教师在教学过程中,教学方法和教学模式要多尝试几种,为了给学生创造学习英语的情境,可以让学生进行口头作文,在平时和学生交流中也可以多用英文,听说读写也是学习英语的好方式,但不能只停留在听、说、读上,英语的书写也很重要。当听说读运用自如的话,再用写来巩固就更好了。
在教学过程中,教师还应该开展丰富多彩的学习活动,在活动中,能够让学生在玩中学习英语。学校也要开展英语教研活动,让英语教师们有互相学习和交流的机会。
七年级学生刚从小学升上来,作文写作技巧还不完善。下面是为大家整理的如何教七年级学生写作文,喜欢可以收藏分享。
小学、初中、高中语文学习的重中之重就是作文,作文也是语文考查中分数占比最高的一大版块。语文考试的得分大头在作文,所以作文写得好不好,决定了语文成绩能不能到中上等,对于孩子今后的学习成绩提高很有帮助。
作文写作其实并没有想象中那么难,孩子写不好作文的原因多种多样,下面我们就简单介绍一些常见的原因。首先是在平时的时候,缺乏知识积累,知识积累少了,导致写作的时候没有了素材。其次是写作没有技巧,写出来的句词搭配不当,导致写出来的作文乱七八糟的。最后是写作的时候没有思路,只知道平铺直叙,不知道如何去构思作文。
写作文是需要技巧的,写作文乱写会让作文丧失美感,如果连很有耐心的阅卷老师都看不下去的作文,那就是很差的作文了。写作文要根据作文格式一点一点往下写,一般作文文体就那几种,比如议论文、说明文等。像有些同学,想一句写一句,这样的写作方式,只会让作文显得杂乱无章,不具备阅读美感,自然也得不到高分。
因此为了帮助孩子提升写作水平,这些写作技巧分享给大家。
比如写外貌的时候,不要用“有”,要详细描写,而不是想到什么特点就用“有”字来连接。
再比如少用成语,作文为什么写不长,可能是成语运用太多了。试着将成语的含义详细写出来,也许会有不一样的效果。
这些写作技巧大家可以根据实际情况运用起来,相信只要下功夫就能有所提高。

七年级生物大家学习得怎么样?下面是为大家整理的七年级生物知识点总结归纳,喜欢可以收藏分享。
七年级生物知识点包括但不限于认识生物、了解生物圈等。
一、认识生物
1、生物的特征
(1)生物生活是需要营养的。
(2)能进行呼吸的是生物。
(3)生物可以排出体内产生的废物。
(4)生物对外界刺激能够做出反应。
(5)生物可以生长和繁殖。
(6)生物有特性,例如遗传和变异。
(7)生物是由细胞构成的,病毒除外。
2、观察和调查是科学探究的基本方法
二、了解生物圈
1、生物圈:
生物圈是地球上所有的生物与其环境的总和。
2、生物与环境的关系
生物的生存空间,以及存在于它周围的各种影响因素都是生物的生活环境。生态因素是环境中影响生物的生活和分布的因素。生态因素可分为光、水分、温度等非生物因素和影响某种生物生活的其他生物等生物因素。
3、生物与环境组成生态系统
(1)生态系统的概念:
生物与环境在一定的空间范围内所形成的统一整体叫生态系统。森林、农田、草原、湖泊等都可以作为一个生态系统。
(2)生态系统由两部分的组成:
一是生产者、消费者、分解者等生物部分。
二是阳光、水、空气、温度等非生物部分。
(3)生态系统中的生产者是植物,生态系统中的消费者是动物,生态系统中的分解者是细菌和真菌。在一般情况下,生态系统中数量最大的应该是生产者。
(4)食物链和食物网:
不同生物之间,在生态系统中由于吃与被吃的关系而形成的链状结构就叫食物链。
生态系统中往往有很多条食物链,彼此交错连接,形成食物网。
①沿着食物链和食物网流动的是生态系统中的物质和能量。
②食物链的起始环节是生产者,食物链的终点为消费者,且不被其他动物捕食。
③生物数量随着营养级越高越少。
④沿食物链,有毒物质进行着积累,越高营养级别的生物体内的有毒物质积累越多。
(5)生态系统具有一定的自动调节能力:
生态系统中生物的数量和所占比例在一般情况下是相对稳定的。这说明生态系统有一定自动调节的能力。但自动调节能力是有限度的,超过就会被破坏。
4、生物圈是最大的生态系统
(1)生物圈的范围:
水圈的大部、岩石圈的表面、大气圈的底部就是生物圈。
(2)生物圈为生物的生存提供了基本条件:
水、适宜的温度,还有营养物质、阳光、空气以及一定的生存空间。
(3)生态系统的类型:
绿色水库、地球之肺等森林生态系统、草原生态系统、湿地生态系统、淡水生态系统、农田生态系统、海洋生态系统、城市生态系统等,湿地生态系统是地球之肾。
七年级生物需要使用显微镜。下面是为大家整理的七年级生物练习使用显微镜方法,喜欢可以收藏分享。
七年级生物练习使用显微镜首先要了解显微镜的构造。
显微镜的镜座一般是稳定镜身。镜柱是为了支撑显微镜镜柱以上的部分。显微镜的镜臂就是大家握镜的部位。显微镜放置玻片标本的地方就叫载物台。载物台的中央有通光孔,两旁各有一个用于固定所观察的物体的压片夹。遮光器上面有大小不等的圆孔叫光圈,每个光圈都能对准通光孔,可以用来调节光线的强弱。
显微镜的反光镜是可以转动的,能让光线经过通光孔反射上来。反光镜两面是不同的,在光强的时候使用平面镜,在光弱的时候使用凹面镜。
显微镜的镜筒的上端装目镜,下端有转换器,在转换器上装物镜,后方有准焦螺旋。
准焦螺旋有粗准焦螺旋和细准焦螺旋。
粗准焦螺旋:
在转动的时候,镜筒升降的幅度大。
细准焦螺旋:
在转动的时候,镜筒升降的幅度很小。
接下来我们介绍一下显微镜的使用。先取镜和安放,再对光,再观察,最后收镜装箱。
从目镜内看到的物像是倒像,观察到的物像是与实际图像相反的。在这里要注意的是,玻片的移动方向和视野中物象的移动方向也是相反。
放大的倍数越大,观察的物像越大,但观察的视野范围就越小,观察到数目越少。物镜倍数乘目镜倍数就是放大倍数。
观察的生物标本要想放在显微镜下应该薄而透明,光线能透过,才能观察清楚。因此要制成玻片标本,切片、涂片、装片都是常用的玻片标本,大家要注意三者的区别,有临时和永久之分。英国物理学家罗伯特虎克通过观察软木薄片发现了细胞。
七年级生物需要学习生物圈知识点。下面是为大家整理的七年级生物了解生物圈知识点,喜欢可以收藏分享。
地球上所有的生物与其环境的总和就是生物圈的定义。
生物圈里生活环境的定义是生物的生存空间和周围的影响因素。
生态因素指的是环境中影响生物生活和分布的因素。
生态因素有非生物因素和生物因素两种分类。
阳光、空气、温度、水、土壤性质等是非生物因素。
影响某种生物生活的其他生物是生物因素。
捕食关系、竞争关系、合作关系、寄生关系等形成生物与生物之间的关系。
生物与环境之间的关系是生物能适应环境,也能影响和改变环境。非生物的无机自然环境和其他生物都是生物生存的环境。在环境中生存的生物,为生物的生存提供物质和能量的是环境,以及栖息场所。生物之间的关系包括种间关系和种内关系,既互助也斗争。
生态系统指的是生物与环境在一定的空间范围内所形成的统一整体。
生态系统中非生物部分包含阳光、空气、水、温度、土壤等。将生态系统中的每个环节中的所有生物分别称重的话,重量最重的应该是生产者。
生态系统中,生物种类和数量越多,食物链和食物网越复杂,自动调节能力越强,森林生态系统就比草原生态系统自动调节能力强。
生物圈范围是以海平面来划分的,向上10千米,向下10千米,共20千米。大气圈的底部,水圈的大部和岩石圈的表面都囊括其中。可飞翔的鸟类、昆虫、细菌等一般生活在大气圈的底部,距海平面150米内的水层是水圈的大部,一切陆生生物的“立足点”在于岩石圈的表面。
