七年级英语三单元范文1
Do you know folk songs? Ballads are now one of the most popular music styles. I like folk song very much, and I fell in love with it after listening to folk song once. If you like folk music, you must know Stephen Foster. I like Stephen Foster, he is a famous folk composer, he is one of the most famous American songwriters, his music works once made a sensation. He's been playing guitar since he was two! When he was ten years old, he could play many songs. He hates school and is only interested in music. When he was 18, he began to compose music. He and his works are so famous, he is really great, he is my idol!
And I also know that there's a Country Music Hall of Fame Museum in Nashville, and there's a lot of famous musicians and singers who do a lot of music concerts there, like Carth Brooks. Folk song is a traditional style of music popular in the southern United States. Now a lot of English is about modern life, their lyrics are about money and success and so on, just about a small group, not the whole group. Folk songs often express rich feelings. They are close to People's Daily life and symbolize the beautiful days. Folk songs tell us that the best things are in our lives and that they are not expensive -- freedom, laughter, friends, family, and beautiful natural scenery. Folk song's tune is easy and melodious, the lyrics are very meaningful, so I like folk song so much.
七年级英语三单元范文2
初一下册生物第三单元知识点
第一章 生物圈中有哪些绿色植物
1、生物圈中的绿色植物类群有：藻类植物、苔藓植物、蕨类植物、种子植物，其中前三种植物生长到一定的时期会产生一种叫做孢子的生殖细胞。因为通过孢子进行繁殖，所以又称为孢子植物(没有
种子植物)。
2、藻类植物大多数生活在水中(如 淡水：水绵，衣藻 海水：紫菜、海带) (1)形态结构：没有根、茎、叶的分化。
(2)营养方式：藻类植物细胞里都含有叶绿素能进行光合作用，营养方式为自养。
(3)繁殖方式：用孢子进行繁殖。
3、藻类植物在生物圈中作用：
(1)生物圈中氧气的重要来源
(2)水生生物的食物来源(如 鱼类饵料)
(3)供食用(如 海带 紫菜)
(4)药用
4、苔藓植物大多数生活在陆地上的潮湿环境(葫芦藓、地钱、树干苔藓)。
(1)形态结构：一般都很矮小，通常具有类似茎和叶的分化，但是茎中没有导管，叶中也没有叶脉，根非常简单，称为假根(只起固定植物体作用)。
(2)营养方式：苔藓植物细胞里都含有叶绿素，能进行光合作用
(3)繁殖方式：用孢子(生殖细胞)进行繁殖。苔藓植物是监测空气污染程度的指示植物。
5、蕨类植物多数生活在阴湿的环境中(如 里白、贯众、满江红)。
(1)形态结构：有根、茎、叶的分化，在这些器官中有专门运输物质的通道——输导组织。
(2)营养方式：蕨类植物细胞里都含有叶绿素能进行光合作用，营养方式为自养。
(3)繁殖方式：用孢子(生殖细胞)进行繁殖。
蕨类植物与人类的关系及其在生物圈中的作用：
(1)可供食用，如蕨菜。
(2)可供药用，如卷柏、贯众等。
(3)作为绿肥和饲料，如满江红。
(4)煤的来源
6、种子植物的分类：根据子叶数目分为
(1)双子叶植物：胚里具有两片子叶的植物(叶脉网状)，营养都储存在子叶中。如 蚕豆、大豆、花生。
(2)单子叶植物：胚里具有一片子叶的植物(叶脉弧形)，营养大部分储存在胚乳中。如 水稻、小麦、高粱。
7、种子的结构：
(1)种皮：保护作用。
(2)胚(包含胚芽、胚轴、胚根、子叶)是新植物的幼体，将来能发育成一个植物体。
(3)只有单子叶植物有胚乳。子叶、胚乳中储藏的营养物质是胚发育成幼苗时养料的来源。
8、种子和孢子的比较：种子中含有丰富的营养物质，具有适应环境的结构特点，如果环境过于干燥或寒冷，它可以处于休眠状态。孢子只是一个细胞，只有散落在温暖潮湿的环境中才能萌发。
9、种子植物的分类：根据种子外有无果皮包被分为①裸子植物(如：松、银杏、苏铁、红豆杉、水杉、圆柏、侧柏)②被子植物
10、被子植物成为地球上分布最广泛的植物原因：被子植物一般都具有非常发达的输导组织，从而保证了体内水分和营养物质高效率地运输;它们一般都能开花和结果，所结的果实能够保护里面的种子，不少果实还能帮助种子传播。
第二章 被子植物的一生
1、被子植物的一生：要经历种子的萌发 ，植株的 生长、开花和结果。
2、种子萌发的环境条件：
(1)适宜的温度(2)一定的水分(3)充足的空气
自身条件：①种子和胚是完整的②胚是活的(在寿命期内)③种子不在休眠期。保存种子、不让其萌发需要控制环境条件是：降低温度、环境干燥、减少氧气。
3、种子萌发的过程：①种子首先吸收水分膨胀②同时子叶或胚乳中的营养物质逐渐转运给胚根、胚芽、胚轴③胚根发育成根④胚轴伸长，连接根和茎⑤最后胚芽发育成芽，芽进一步发育成茎和叶。
4、根尖的结构和功能
① 根冠：具有保护作用。
② 分生区(分生组织)：分裂产生新细胞，不断补充伸长区的细胞数量。
③ 伸长区(生长最快的部位)：下部细胞较小，越往上细胞越大，最后成为成熟区细胞的一部分。
④ 成熟区：表皮细胞一部分向外突出，形成根毛，是根吸收水分和无机盐的主要部位。
5、幼根的生长：一方面要靠分生区细胞的分裂增加细胞的数量;另一方面要靠伸长区细胞的体积的增大。
6、芽的分类 ①顶芽②侧芽。芽的发育 幼叶发育成叶，芽轴发育成茎，芽原基发育成芽。枝条由幼嫩茎、叶、和芽组成的，其上的芽还能发育成新的枝条。
7、植物生长需要多种无机盐，需要量最多的是含氮的(缺氮时，植株矮小瘦弱，叶片发黄)、含磷的(缺磷时，植株特别矮小，叶片呈暗绿色，并出现紫色。)、含钾的(缺钾时，植株的茎秆软弱，容易倒伏，叶片边缘和尖端呈褐色，并逐渐焦枯。)
8、可以进行无土栽培的原因：植物的根从土壤中吸收的仅是水分和无机盐。给植物打针输液：输入的液体中含有水分和无机盐，以促进植物的生长，针头应插入树木的输导组织中。“有收无收在于水，多收少收在于肥”这句农谚说的是对于庄稼来说，它的成活、生长和收获，在于浇水的方式、方法;而庄稼收获的多少，在于对它施肥的时间、方式和施肥量。这说明了水、肥对于农业生产的重要性。
9、花的主要结构：
(1)雌蕊 ①柱头 ②花柱 ③子房(内有胚珠含卵细胞)
(2)雄蕊 ①花药(内有花粉含精子)②花丝。
10、传 粉：花粉从花药中散放而落到雌蕊柱头上的过程。
传粉的类型：
① 自花传粉(如 小麦、水稻、豌豆)
② 异花传粉花粉依靠外力落到另一朵花的柱头上的传粉方式。异花传粉靠媒介主要是风和昆虫。花朵的色彩和香味可以把昆虫吸引过来，昆虫在采食花蜜或花粉时，帮助植物传粉。
在果树开花季节，如果遇到阴雨连绵的天气，常会造成果树减产。原因是因为果树的传粉受到了影响。在生活中，我们经常发现玉米的果穗有缺粒的;吃瓜子时，子粒常有空瘪的原因是传粉不足，解决办法是人工辅助授粉。
11、受精的概念：胚珠里面的卵细胞，与来自花粉管中的精子结合，形成受精卵的过程。
受精的过程：(1)长出花粉管。(2)花粉管穿过花柱，进入子房，一直到达胚珠。(3)花粉管中的精子与胚珠中的卵细胞结合形成受精卵。
12、果实和种子的形成：子房发育成果实。子房壁发育成果皮，珠被发育成为种皮，胚珠发育成种子，受精卵发育成胚。
受精完成后，花瓣、雄蕊以及柱头和花柱纷纷凋落，惟有子房继续发育，最终成为果实。
13、黄瓜、南瓜、丝瓜这些植物在同一株植物上，有的花是雄花，有的花是雌花，一般情况下雄花的数量会多于雌花。那些只开花不结果的花是雄花。
第三章 绿色植物与生物圈的水循环
绿色植物的生活需要水，水会影响植物的分布。
1、植物主要通过根吸收水分。根吸收水分的主要部位是 根尖成熟区 。成熟区有大量的 根毛，这使得根尖具有巨大的 吸收面积 ，因而具有强大的吸水能力。
2、导管(属于输导组织)导管是运输水分和无机盐的通道
筛管：向下输送叶片光合作用产生的有机物
茎的结构包括木质部和韧皮部。 在二者之间有形成层，形成层向外分裂形成韧皮部，向内分裂形成木质部。有些植物茎中没有形成层，因而不能长得很粗。
茎从外到里：树皮;韧皮部(有筛管);形成层;木质部(有导管)
叶片的结构：表皮(分上下表皮)、叶肉、叶脉
气孔的结构：气孔由两个保卫细胞组成，保卫细胞吸水膨胀，气孔张开;保卫细胞失水收缩，气孔关闭。白天气孔张开，晚上气孔闭合。
蒸腾作用的意义：
①可降低植物的温度，使植物不至于被灼伤。 ②是根吸收水分和促使水分在体内运输的主要动力。 ③可促使溶解在水中的无机盐在体内运输。④促进生物圈水循环。
3、蒸腾作用：水从活的植物体表面以水蒸气状态散失到大气中的过程。主要通过叶片实现
4、叶片由 表皮(上表皮和下表皮)、 叶肉 与 叶脉 三部分组成。表皮分布有气孔，气孔是植物蒸腾作用的“门户”，也是气体交换的“窗口”。气孔是由一对半月形的细胞—保卫细胞围城的空腔，保卫细胞吸水膨胀时，气孔张开;当保卫细胞失水收缩时，气孔关闭。
5、蒸腾作用的意义：① 拉动水分与无机盐在植物体内的动输;②通过蒸腾作用能降低叶片表面的温度③提高大气湿度，增加降水。
6、绿色植物在水循环中起作用：①植物蒸腾作用能够提高大气湿度，增加降水。 ②植物的茎叶承接着雨水，能够大大减缓雨水对地面的冲刷。③树林中的枯枝落叶能够吸纳大量的雨水，补充地下水。
第四章 绿色植物是生物圈中有机物的制造者
1、绿叶在光下制造有机物实验步骤：暗处理、遮光处理、酒精脱色、漂洗叶片 、滴加碘液、清洗叶片、观察叶片颜色。
实验注意事项：
①把天竺葵提前放到黑暗处一昼夜原因是使叶片中原来贮存的淀粉转运和消耗掉，
②实验中要用黑纸片把叶片的一部分遮盖起来。原因：为了做对照实验。
绿叶在光下制造有机物实验得到如下结论：
①淀粉是光合作用的产物。
② 光是绿色植物制造有机物不可缺少的条件。
③叶绿体既是生产有机物的“车间”，也是将光能转变为化学能的“能量转换器”。
植物通过光合作用制造有机物：天竺葵的光合作用实验(P117)
①天竺葵放黑暗处一昼夜：将叶片内原有淀粉转运消耗掉
②叶片的一部分用黑纸片从上下两面遮住：对照实验
③为什么要用酒精隔水加热：酒精只能隔水加热，否则将发生危险!
④为什么要漂洗叶片：洗去多余的酒精才不会干扰试验效果
⑤绿叶在光下制造的有机物是：淀粉
2、光合作用实质：绿色植物通过叶绿体，利用光能，把二氧化碳和水转化成储存能量的有机物(如淀粉)，并且释放出氧气的过程。
3、绿色植物制造的有机物意义：①满足植物自身生长、发育、繁殖的需要;②绿色植物作为生物圈中的生产者，制造的有机物，通过食物链、食物网，养育了生物圈中的其他生物。
第五章 绿色植物与生物圈中的碳-氧平衡
1、普利斯特利实验得出的结论：植物能够更新由于蜡烛或动物呼吸而变得污浊的空气
2、探究实验二氧化碳是光合作用原料步骤：暗处理、把插有天竺葵的两个小烧杯分别放入装有清水和25%氢氧化钠溶液的水槽中去，编号A、B组，放在日光下、酒精脱色、漂洗叶片 、滴加碘液、清洗叶片、观察叶片颜色。
3、光合作用表达式：原料二氧化碳水条件光场所叶绿体 产物有机物和氧气
4、光合作用原理在农业生产上的应用：
(1)合理密植，让作物的叶片充分地接受光照。
(2)增加二氧化碳的浓度，给温室里的农作物施用贮存在钢瓶中的二氧化碳，以增加农作物的产量，这种方法称为气肥法，二氧化碳被称为“空中肥料”。
5、卧室里摆放多盆绿色植物是不科学的原因是：有光照时，绿色植物同时进行光合作用和呼吸作用，可以更新居室的空气。在黑暗中，绿色植物的光合作用停止，呼吸作用仍在进行，会消耗居室内的氧气，将二氧化碳排放到居室中，影响居室内的空气质量。
6、呼吸作用(概念)细胞利用氧，将有机物分解成二氧化碳和水，并且将储存在有机物中的能量释放出来，供给生命活动的需要。其实质是分解有机物，释放能量。任何活细胞都在不停地进行呼吸作用。
▲光合作用和呼吸作用的区别和联系
光合作用
呼吸作用
含叶绿体的细胞
所有活细胞
在光下才能进行
有光无光都能进行
二氧化碳和水
有机物和氧气
有机物和氧气
二氧化碳和水
物质转化
将二氧化碳和水合成为有机物
将有机物分解成二氧化碳和水
能量转化
将光能转化成储存在有机物中的能量
将有机物中的能量释放出来
光合作用为呼吸作用提供物质基础
呼吸作用为光合作用提供能量
▲(理解)呼吸作用与生产生活的关系：中耕松土、及时排涝都是为了使空气流通，以利于植物根部进行呼吸作用。植物的呼吸作用要分解有机物，因此在储存植物的种子或其他器官时，要设法降低呼吸作用，如降低温度、减少含水量、降低氧气浓度、增大二氧化碳浓度等都可抑制呼吸作用。
▲光合作用与生产生活关系：要保证农作物有效地进行光合作用的各种条件，尤其是光。合理密植。使作物的叶片充分地接受光照。
8、呼吸作用在生产生活中的运用 ：
(1)对于活细胞而言，增强呼吸作用，保证正常生命活动的能量供应(农田适时松土，遇到涝害时排水 )
(2)对于死细胞而言，降低呼吸作用强度，减少有机物消耗。(食物储存过程中保持干燥，降低温度，减少氧气浓度)。呼吸作用是生物的共同特征。
9、绿色植物进行光合作用，产生由于生物呼吸作用或者燃料燃烧消耗的氧气，吸收其释放出的二氧化碳，对于碳--氧平衡有非常重大的意义。
10、栽花或种庄稼需要松土，是为了使植物的根得到充分的氧气，保证呼吸作用的正常进行。储藏甘薯、白菜的窖必须留有通风孔，是因为甘薯、白菜进行呼吸作用产生了热量，会导致窖内温度升高，而温度升高又会导致呼吸作用加强，消耗农作物的营养，使农作物的品质下降。若浇花过勤，花土总是含有大量的水分，这样会导致根烂掉，植物死亡，其原因是水分过多，根无法呼吸。在昼夜温差较大的地区，粮食作物饱满，果树和瓜类果实较甜，这是因为白天光合作用旺盛，晚上呼吸作用微弱。
第六章 爱护植被 绿化祖国
1、植被：一个地区内生长的所有植物。
2、我国主要的植被类型(六种) 草原 荒漠 热带雨林 落叶阔叶林 常绿阔叶林 针叶林
3、我国植被面临的主要问题 ①人均森林面积减少 ②森林生态系统呈现衰退趋势 ③草原退化、沙化严重
4、从我做起，保护植被 我国相继颁布防止我们生存环境恶化的法律：1984年《_森林法》1985年《_草原法》《退耕还林条例》 开展了开展了植树、种草等活动，确定每年的3月12日为植树节
▲我国主要的植被类型 草原、荒漠、热带雨林、常绿阔叶林、落叶阔叶林、针叶林
▲我国植被面临的主要问题 植被覆盖率低，森林资源和草原资源破坏严重
▲我国森林覆盖率
▲我国每年3月12日为植树节
▲热带雨林-----地球的肺
▲生物圈的“绿色工厂”----绿色植物。
▲如果将绿叶比做制造有机物的“工厂”，它的机器是叶绿体，动力是光，原料是二氧化碳和水，产物是有机物和氧气，条件是光和叶绿体。场所是叶绿体，具体部位是叶绿体的细胞。
初中生物学习方法指导大全
(一)进化的观点。
现在地球上的生物是经过漫长的年代逐渐进化来的。即沿着从简单到复杂、从水生到陆生、从低等到高等的历程进行着。《形形色色的植物》、《动物》部分在结构上均是按照其进化顺序来安排的，并强调了植物和动物在形态结构上与环境是相统一的，是长期进化的结果。尤其将《生物的进化》单列一章，其意图更为明显。
(二)适应的观点。
从《绿色开花植物》的每一章、《细菌、真菌和病毒》、《人体生理卫生》部分无不体现出其结构与功能的适应性;《动物》部分既体现出形态结构与生活习性的相适应性，又体现了结构与功能的适应性。
(三)动态的观点。
从细胞质的流动及其与外部环境的物质和能量的交换，到生物各个器官生理之间相辅相成又彼此制约的相互联系，使整个教材内容都贯穿了动态的观点。
(四)生态学的观点。
《绿色开花植物》部分、《动物》部分都是在个体水平上对生态学作了论述，尤其将《生物与环境》单列为一章，阐述了生物与环境的关系及其形成的统一性、以及强调保护自然资源的重要意义。
理解这些观点，是学好初中生物的重要前提。

音乐巨人贝多芬
一、文学常识
贝多芬，德国作曲家，音乐家，代表作《命运交响曲》。 二、字词
深邃 磐石 门槛 重荷 捏弄 踌躇 喧嚣 纽扣 下颏(kē) 喃喃(nán) 惹人注目 杂乱无章 不见天日 坚忍 蓬勃 小心翼翼
三、中心思想
通过对贝多芬肖像和语言的描写，再现了贝多芬的形象，着重表现他内心世界的痛苦和对不幸命运的顽强抗争。 四、句子解析
1、为什么贝多芬说“一株树也比一个人好”?
耳聋给他造成了交流的障碍，常常被人误解，而一棵树尚且可以听到大自然的声音;另外，耳聋后的贝多芬可以远离人世的喧嚣和纷争，获得心灵的纯净和安宁。
2、将“耳聋”比喻成“囚牢”有什么表达作用? 生动形象地表明耳聋带给贝多芬的极大不幸。
3、为什么贝多芬说“一个乐队只能奏出我在一分钟里希望写出的音乐”? 贝多芬用他的整个生命和热情从事音乐创作，而乐队只能奏出有声的音符，却不能完美传达心灵的律动和生命的节奏，即贝多芬心里的音乐。
4、“他诚然孤独，可是有“永恒”为伴”中“永恒”指什么?
“永恒”指作为心灵载体的音乐艺术。意思是尽管贝多芬耳聋了，但这局限又使他超越形体和言辞，直接感知人的心灵世界，朋友会离他而去，会误解他，但音乐却不会。

3、文中“不动不响，无声无闻”能否删去,为什么?
不可以，因为叙述闻一多先生研究学问的事迹是为了证明闻一多在做学问上不“说”而做。这八个字与全文呼应，也起到了印证作用，同时也起到强调的作用，强调在不“说”的情况下，却“做”出了卓越的成绩。

When the brook plays the piano, when the spring flowers celebrate the spring, when the warm spring breeze blows, I know that the spring of business is coming.
The spring girl tugged the grass which was sleeping under the ground, and woke up the flowers hidden underground. The jujube tree in the courtyard also seems to have just been awakened from the dream by the spring girl, when it wakes up, the body is bare, still hangs a few withered leaves! But within a few days, the body was covered with green, tender leaves. It swung the branches, invited the birds to visit, shook branches, and greeted the spring girl.
The willows of the river began to draw out new branches, and the leaves were green, and they were as sharp as a sword, and like a few brothers and brothers. It reminds me of a poem about willow, which is made up of a tree and a thousand pieces of green silk. The spring breeze is like a pair of scissors in February. Colorful flowers make up a colorful painting, red and bright, white, beautiful, pink, and full of spring. Then the wild geese flew back from the south, formed _human_ in a moment, formed _big_ in a moment, and formed _one_ in a moment.
I like snowy winter, I like fruitful autumn, I like hot summer, but I prefer colorful spring!

What kind of teacher do I like? I may not be able to answer this question for a half time. Generally speaking, boys will love beautiful and gentle, liberal and dignified teacher; girls will love the teachers, courteous and accessible courtly and gentle but I love such a teacher......
I like the knowledgeable teacher, only the teacher has the rich knowledge, can teach us more knowledge, can let us in the society.
I like a lively atmosphere, so I do not like a teacher like white water, the class is so dead, it is not good for our study. Of course, the teacher is not able to speak humorous language in class.
I like to drive my brain and turn a few more corners to the end, rather than to go straight to the end. So the teacher must not just speak, but also give us the space to imagine.
I like to be fair, so the teacher should be equal to every student. Most of the teachers in junior high school ignore the poor students, which will hurt the young minds of their classmates. We are the flowers of our country, so please don't trample them.
I like the teacher who can get together with the students, so that there will be no separation and contradiction between the students and the teachers. The teacher is our big friend, can have any heart matter to be able to talk with the teacher......
I have this special feeling for the bell, so the teacher can not Tuotang oh! The teacher often teaches us, _time is money, Time is money_, although only a class ten minutes, but it is time we should cherish.
This is the teacher I like.
