非生物与生物间有关联作文

非生物与生物间有关联作文

非生物与生物间有关联作文英文回答:Non-living and living things are interconnected in many ways. One of the most obvious connections is the way non-living things provide essential resources for living organisms. For example, plants use sunlight, water, and nutrients from the soil to grow and thrive. In return, plants provide oxygen for animals to breathe and serve as a food source for many organisms.Another way non-living and living things are connected is through the carbon cycle. Non-living things, such as rocks and the atmosphere, store carbon, which is then released into the environment through processes like volcanic eruptions and the burning of fossil fuels. Living things, such as plants and animals, also play a role in the carbon cycle by absorbing and releasing carbon dioxide through processes like photosynthesis and respiration.Furthermore, non-living things can have a direct impact on the behavior and distribution of living organisms. For example, the availability of water and temperature can greatly affect where certain species are able to live and thrive. Additionally, non-living things like soil and air quality can impact the health and well-being of living organisms.Overall, the relationship between non-living and living things is complex and multifaceted, with each depending on the other in various ways.中文回答:非生物和生物之间有许多关联。

生物与非生物

生物与非生物

生物与非生物生物与非生物什么是生物呢?在我们的日常生活中,我们可以轻松地区分出生物和非生物。

人、动物、植物、细菌等都属于生物;而石头、钢铁、玻璃、水、沙子等则属于非生物。

那么,这两者之间究竟有何不同呢?生命的起源首先,生物和非生物最基本的差别在于生命。

生物都拥有自己的生命,而非生物则没有。

生命是生物特有的一个属性,它最初的起源至今仍然是一个谜。

人们普遍认为,生命源于某种原始的生命体,或者是以细胞为基础的有机体的进化。

这些细胞自身就是复杂机构的基础,包括DNA、核、细胞质和细胞膜等。

这些组成部分随着时间的推移,逐渐演化成更为复杂的生命形式。

生物的特征除了生命以外,生物还具有许多其他的特征。

生物具有复杂的组织结构,这些组织可以完成特定的功能。

比如,我们的身体就是由骨头、肌肉、器官、器械等许多不同的组织构成的。

它们能够协同工作,保持身体的正常运转,同时反应出我们的感受和思想。

另外,生物还有自主的行为。

这些行为可以是根据环境改变而自发进行的,也可以是出于心智和决策的能力而进行的。

生物可以感知外界环境,通过判断和响应来变得更加适应。

比如进入冬眠、迁徙或是躲避危险等。

与此相对的是非生物,它没有自己的心智和行为。

非生物的运行方式是静态的,它们的行为一般是对外界刺激的反应。

比如石头在受到力量作用时,会产生碎裂或移动等反应。

而机器的运作也是靠程序的判断和处理进行的,是人类意识所设计和控制的。

这是与生物根本不同的。

生物的进化有趣的是,在生物中存在着进化的概念,但是在非生物中没有。

生物的进化是利用遗传变异和自然选择这两个过程来达到的。

如果一个组织的基因发生了变异,那么这一变异也会在后代中体现出来。

如果这个变异增强了这个组织的适应性,那么它也会具有更大的生存优势,更高的繁殖率。

最终,新的特征就会在种群中广泛传播,成为种群的一部分。

与此相对的是,非生物不会进化,它们也不会适应环境。

虽然它们可以随着时间的推移发生物理和化学变化,但这些变化并不会增强它们的适应性。

1.In the dark street, there wasn’t a single person to____ she could turn for help.答案与解析:whom。

题中包含短语“turn to sb. for help”,意思是“向某人求助”。

本句可以转换成:In the dark street, there wasn’t a single person (whom/ who/ that)she could turn to for help. 属于“介词+关系代词”结构。

句意是:在漆黑的大街上,连一个她可以求助的人都没有。

2.______ has been announced, we shall have our final exam next month.答案与解析:As。

考查非限制性定语从句。

这是as引导非限制性定语从句,先行词是后面的整个句子,关系代词as指代后面的主句的内容,在定语从句中as作主语,意思是“正如”。

句意:正如宣布的那样,下个月我们要举行期末考试。

3.There comes a time________ the old must give way to the new, and it is not possible to preserve everything from our past as we move towards the future.答案与解析:when。

• Many birds move from one place to anther because of climate change.
• Human beings also move, we can walk, dance, jump, and climb. Some of us can also swim.
Living things can excrete waste.
• The waste is harmful to the body, so it is necessary to remove the waste from animals’ bodies.
• Plants also need to remove the waste, you will see the leaves and bark fall or drop yearly.
• Plants movement is not tht can move part of their bodies to get what they need.
Living things can grow.
• All living things can grow to be big and heavy. A seed can grow into a tree and a baby can grow into a child.
Characteristics of living things
1 .Living things can move. 2. Living things can grow. 3. Living things can breathe and respire. 4. Living things can reproduce. 5. Living things can respond to stimuli. 6. Living things can excrete waste. 7. All living things need food to keep alive.
All living things need food to keep alive.
• We all know that food provides energy for living things. Without food, living things will die soon.
• But different organisms take in different kinds of food.
Living things can breathe and respire.
• Most living things need air to keep alive. Most animals with back bones, like humans, birds, reptiles use lungs to breathe.
• Fishes use their gills to breathe.
• Most of the animals without backbones, like the insects, shrimps and mollusks use lungs to breathe.
• The plants breathe through their leaves.
The definition of living and non-living things
Living things have seven characteristics below and non-living things don’t have all the characteristics that livings have.
Living things can reproduce.
• All living things can reproduce. • Animals produce babies or eggs and
plants produce seeds. • The babies and seeds are called
• Now ,can you tell us why a car, a fan and a balloon are not living things though they move or float?
Living things can respond to stimuli.
• Responding to the stimuli is the knowledge or ability which allows animals and people naturally to act in particular ways without having to think or to be taught. So, whenever there is a stimulus, living things will respond to it immediately.
offspring. • The parent animals and plants pass on
their features to their offspring.
• Without reproducing, humans and animals can’t live generation after generation, the society and the nature can’t develop or be improved.
Living things can move.
• Many animals can move their bodies from one place to anther. They move because of escaping danger or trying to find food or water.
