相信很多的高考生会关心高考生物必考的知识点,那么高考生物知识点及公式有哪些呢?以下是小编准备的一些高考生物知识点及公式大全,仅供参考。
(1)努力搜寻教材相关知识。
根据题目考查的知识点,努力搜寻教材相关内容是解题的关键。答题一定要有依据,很多信息题背景虽新,但考查的知识点却落脚于教材,所以,一定要用好题目中的一些关键词,努力转化成教材中学过的知识而进行破题。
(2)认真分析选择题干和选项的逻辑关系。
生物之所以是理科,是因为它具备严密的逻辑推理性。因此,答题时一定要认真思考推理,进而得出正确答案。
(3)掌握一些常用的答题小技巧。
近几年高考生物选择题中,涉及“正确的是”、“不正确的是”、“错误的是”的试题约占一半。所以,我们一定要好好利用好“错误原理”,这类题目才能迎刃而解。
生物被誉为“理科中的文科”,很多知识点是需要考生记忆的。那么高考生物知识点归纳总结有哪些呢?以下是小编准备的一些2024高考生物知识点归纳总结,仅供参考。
(1)先易后难
高考生物解题要按先易后难的顺序进行,不能碰列难题就抓住不放,更不可一开始考试就专挑难题入手。
(2)胆大心细
所谓“胆大”,就是‘定要有坚定的信心,激起自己的斗志,全力以赴。“心细”就是指答题过程一定要仔细,从审题到思考到落笔,都必须细心周到。避免因粗心而导致失分。
(3)科学作答
①答高考生物题时尽量用生物学的专用术语,而且要用得准确。要尽量使用规范化的学科语言。
②尽量用生物课本用语进行表述。对说明性的表达,常常可以落脚到课本上的结论性叙述上。比如,根对水分和矿质离子的吸收是两个相对独立的过程;细胞是‘一个统一的整体;生态系统具有一定的自我调节能力;
③话要说完整。要使别人能看明白,而不仅仅是自己心中知道。
④生物答案要准确,要做列层次清晰、条理清笔、逻辑严谨。答案宜简洁明了,切不可重复哆唆,以免造成不必要的丢分。要紧扣基本观点。

【附译文】
元和十年(815),(柳宗元)按旧例被移作柳州(今属广西)刺史。那时朗州司马刘禹锡被移作播州刺史,诏书下达时,柳宗元同自己亲近的人说:“刘禹锡有老母,年龄已大,如今他要到蛮方远郡去做刺史,在西南绝域的地方,来回有上万里的路程,哪能让他和老母一起去。如果(母亲不去,)母子各在一方,这便成永别。我和禹锡是好朋友,我哪能忍心看他母子这样呢?”于是立刻起草奏章,请求把柳州授给刘禹锡,自己却到播州上任。恰巧裴度也奏请照顾刘禹锡母子,所以刘禹锡最终改授连州(今广东连县)刺史。
柳州风俗,用男或女作为抵押去借钱;如果过期没还钱,人质便被钱主所没收。柳宗元到了柳州,便改革掉这种风俗。对那些已经被钱主没收的男女,柳宗元自己出私钱将他们赎回,归还给他们的父母。长江至岭南 之间,凡是想考进士的人,不远千里都来跟随柳宗元,拜他为师;凡是经柳宗元指点过的人,一定会成为名士。元和十四年(819)十月五日去世,终年四十七岁。观察使裴行立帮柳宗元办理丧事,并护送他的妻子和儿女返回京师,当时的人都赞扬他很有义气。

11.不能替换,“一定”表示肯定,“也许”表示不确定,文中是一个肯定判断,去掉后就不能体现说明文语言的准确性。(2分)
解析:此题考查说明文语言的运用。说明文语言要求准确,回答时从说明文语言的准确性上进行分析。
12.好作品是无法压缩成所谓的精华的(1分)真正能够回馈至生命本身的阅读必须付出时间和精力。(1分)

14.运用了比喻论证的方法,(1分)“玫瑰胶囊”比喻压缩阅读,即以阅读作品的摘要精华为手段的占有性的阅读,(1分)“盛开的红玫瑰”指必须付出时间和精力的从容阅读,(1分)攻瑰胶囊对人体的作用,不能和盛开的红玫瑰相提并论,也就意味着以阅读作品的摘要精华为手段的占有性的阅读,与付出时间和精力的从容阅读,是不能同日而语的。(1分)
解析:此题考査论证方法的运用。这一句运用了比喻说理的方式进行论证,只要理解“胶囊”和“玫瑰”各自的比喻义,把各自的作用分析出来。

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.
( )1. Most earthquakes are too_________ to hurt people.

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。

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。
