我们为什么要植树用英文来回答并带
Plants
Plants are very important living things.Life could not go on if there were no plants.This is because plants can make food from air,water and sunlight.Animals and man cannot do so.Animals get their food by eating plants and other animals.Man gets his food by eating plants and animals,too.Therefore,animals and man need plants in order to live.
If you look carefully at the plants around you,you will find that there are many types of plants.Some plants are large while others are small.Most plants are green.
There are two main types of plants:flowering plants and nonflowering plants.
Flowering plants have roots,stems①,leaves,flowers and fruits.Almost all the trees around us are flowering plants.You can probably recognize some plants from their flowers or their fruits.
Nonflowering plants include coniferous trees,mosses,liver-worts,algae and fungi.You cannot see many nonflowering plants around you.
Most plants do not grow from seeds.They grow from spores.Spores are very,very small.Some spores are so small and light that they can float in the air.We may say that spores are quite similar to seeds.When these spores fall on wet and shady② places,they usually grow into new plants.
用英语谈论植树对人与环境的益处
树木能调节气候,保持生态平衡,树木通过光合作用,吸进二**碳,吐出氧气,使空气清洁,新鲜。一亩树林放出的氧气够65人呼吸一辈子。
Trees to regulate climate, maintaining the ecological balance, the trees through photosynthesis, the inhalation of carbon dioxide, spit out oxygen, make the air clean, fresh. An acre of forest release of oxygen enough for 65 people to breathe for a lifetime.
树能防风固沙,涵养水土,还能吸收各种粉尘,一亩树林一年可吸收各种粉尘20—60吨。
The tree can wind and sand, water and soil conservation, but also to absorb all kinds of dust, an acre of forest a year can absorb all kinds of dust 20 - 60 tons.
树林能减少噪音污染。40米宽的林带可减弱噪音10—15分贝。噪音的污染对人类的生活、学习、工作、休息等方面都造成了很大的危害,可以说是人们的“敌人”。因此我们更要重视植树造林。噪音还可以使人类在长期的生活中听力减弱、耳聋、变傻,心脏、血压、神经等出现异常。甚至,还能让人在长期的噪音煎熬下死亡。这样树林就能使噪音减小四、五倍。
Forest can reduce noise pollution. 40 meters wide belt noise can be reduced 10 to 15 decibels. Noise pollution on human life, study, work, rest and so on have caused great harm, it can be said that people's "enemy"". Therefore, we should pay more attention to afforestation. Noise can also make people in the long-term life of hearing loss, deafness, become stupid, heart, blood pressure, nerves and other abnormalities. Even, can make people in the long-term noise suffering death. Such trees can make noise reduction of fourth and five times.
树木的分泌物能**细菌。空地每立方米空气中有3,4万个细菌,森林里只有300-400个。植树造林是我们每个公民的义务,国家还专门规定了在三月十二日这天为植树节。植树造林对我们的学习、工作、生活等方面都有很大的好处。
The secretions of trees can kill bacteria. Every cubic meter of air space in 30000 or 40000 bacteria, the forest is only a 300-400. Afforestation is our obligation of every citizen, the state also specifically defined in March 12th this day for arbor day. Afforestation on our study, work, life and other aspects of a great benefit.
树可以减低温度,和提高湿度。30度气温可以降到二十几度左右。
Trees can reduce the temperature and increase the humidity. 30 degrees temperature can be reduced to about 20 degrees.
人类对自然资源的不合理开发利用,是造成生态失衡的主要原因。乱砍滥伐、毁林开荒、过度放牧等,会破坏森林和草场,造成水土流失和土地荒漠化,使沙尘暴频繁出现。不合理的开发、占用土地,使耕地面积日益减少,所以植树是有必要的。
The irrational exploitation and utilization of natural resources by human beings is the main cause of ecological imbalance. Deforestation, deforestation, land reclamation, overgrazing, and the destruction of forests and pastures, resulting in soil erosion and land desertification, make frequent sandstorms. Unreasonable development, occupation of land, so that the area of arable land is decreasing, so it is necessary to plant trees.
加涅的学习分类
加涅把人类的学习分为八个层次:
一是信号学习。这是最低级层次的学习。"无论在普通家畜方面或在人类方面,对于信号学习普遍都是熟悉的。"
二是**一一反应学习。加涅认为,这一层次的学习相似于桑代克的"尝试错误学习"和斯金纳的"操作性学习"。它只涉及一个**与一个反应之间的单个联络;而且剌激与反应是统一地联结在一起的。
三是连锁学习。这是一种成系列的单个"S-R"的结合的 学习。有些连锁学习是由肌肉反应组成的,而有些连锁学习完全是言语的。
四是言语联结学习。这是指语言学习中言语的连锁化,包括字词形声义的联想和言语顺序的学习。
五是辨别学习。这是指学习者对某一特别集合中的不同的成份作出不同的反应的学习。
六是概念学习。这是指对事物的共同特征进行反应的学习。 其中有些概念可以通过学习者与环境的直接接触来获得,但有些概念则要运用语言对事物进行分类、归纳和概括才能获得。
七是原理(规则)学习。这是对概念间关系的认识或理解。例如,从 对"圆的东西"和"滚动"两个概念间关系的认识中得出"圆的东西会滚动"的规则。
八是解决问题学习。这是规则学习的一个自然的扩大,是一种"高级规则"的学习。
扩展资料:
一、学习结果
加涅认为,人类的学习有五类结果,表现为五种不同的能力,即言语信息、智力技能、认知策略、运动技能和态度。
一是言语信息。加涅认为,这是一种学习者表述观念的能力。之所以称为"言语信息",是因为"信息是言语的,或者说得比较明确些,信息是可以表达的"。
二是智慧技能。加涅认为,这是学习者使利用符号成为可能的能力咱例如,读写算是低年级儿童所学习的利用符号的基本种类,随着学习的进展,他们就会以比较复杂的方式来利用符号。智慧技能并不是单一形式,它有层次性,由简单到复杂,包括四层次:辨别,概念,规则,高级规则。
三是认知策略。加涅认为,这是学习者用来调节他自己内部注意、学习、记忆与思维过程的能力。认知策略可以应用于任何科目的学习。
四是运动技能。加涅认为,这是学习者学习由许多有组织者的肌肉运动所形成的综合活动的能力。运动技能不是指个别的动作,而是强调动作的完整性和统一性。
五是态度。加涅认为,这是影响个人选择行动的内部状态。 在他看来,人的行动是受态度影响的,但态度又是人的动作的结果。
二、学习过程
每一类学习中都蕴藏着前一类的学习。在加涅看来,任何一个学习过程也是有层次性的,都是由一个个具体的学习阶段构成的。他把学习过程依次分为八个阶段:
动机阶段:一定的学习情境成为学习行为的诱因,激发个体的学习活动,在这个阶段要引发学生对达到学习目标的心理预期.
领会阶段:也称了解阶段,在这个阶段中,教学的措施要引起学生的注意,提供**,引导注意,使刺**境的具体特点能被学生有选择的知觉到.
获得阶段:这个阶段起着编码的作用,即对选择的信息进行加工,将短时记忆转化为长时记忆的持久状态.
保持阶段:获得的信息经过复述、强化之后,以一定的形式(表象或概念)在长时记忆中永久地保存下去。
回忆阶段:这一阶段为检索过程,也就是寻找储存的知识,使其**的过程。
概括阶段:把已经获得的知识和技能应用于新的情境之中,这一阶段涉及到学习的迁移问题。
操作阶段:也叫作业阶段。在此阶段,教学的大部分是提供应用知识的时机,使学生显示出学习的效果,并且同时为下阶段的反馈做好准备。
反馈阶段:学习者因完成了新的作业并意识到自己已达到了预期目标,从而使学习动机得到强化。加涅认为:“值得注意的是强化主宰着人类的学习,因为学习动机阶段所建立的预期,此刻在反馈阶段得到了证实。”
