2、简述原生动物的生态分布特点及其与水产养殖和环境保护的关系自由生活的原生动物在地球上分布极为广泛，只要有水分的地方就有原生动物的生存。

原生动物的分布形式主要是团块型分布。

不同的水域有不同的优势种群的原生动物，原生动物种群数量的变动常表现出周年变化，季节变化等特点。

淡水的原生动物比海洋更加多样化，沿岸区由于栖息环境的复杂化和营养物质的丰富，原生动物种类比远洋区更丰富。

分布在海洋的浮游原生动物以自养型生活的为主。

原生动物可以用来作为污水处理的指标生物，在自然水体中作为有机污染的指示指标。

通常是水生经济动物如鱼、虾、贝类直接或间接的天然饵料。

在养鱼水域中，大量异养原生动物增殖，取食水中藻类，会造成水体缺氧，影响渔业生产。

少数种类大量繁殖，造成近海赤潮发生，危害渔业。

4、简述轮虫的主要特征轮虫是小型多细胞动物，体型虽小但其结构比原生动物要复杂的多，有消化、生殖、神经等系统。

主要特征是具有头冠、咀嚼囊和原肾管。

具有纤毛环的头冠。

轮虫的头部前端扩大成盘状，其上方有一由纤毛组成的轮盘，是运动和摄食的器官。

身体其他部分没有纤毛。

轮虫消化道的咽部特别膨大，形成肌肉很发达的咀嚼囊，内藏咀嚼器。

体腔两旁有一对原肾管，其末端有焰茎球。

全身包以淡黄色或乳白色表皮。

在标准状况下，氧气的密度为11.429g L -⋅，比空气略大。

氧的三态变化（101kPa ）：()()-183-218⎛⎫⎪⎝⎭−−−→−−−→←−−−←−−−℃℃无色淡蓝色淡蓝色雪花状固体气态氧液态氧固态氧 友情提示：氧气考查较多的物理性质是溶解性和密度，利用溶解性和密度可以解释一些自然现象，如高空中氧气的含量、水生动物的生存等。

知能解读：（二）氧气的化学性质氧气是一种化学性质比较活泼的气体，在一定条件下，可以跟多种物质发生化学反应，同时放出热量，氧气具有氧化性，在化学反应中提供氧，是一种常用的氧化剂。

注意：①氧气可以帮助可燃物燃烧（或支持燃烧），具有助燃性，与可燃性有本质区别。

②“剂”是一种发生某种变化的作用物质，如氧气具有氧化性，是常用的氧化剂，氧气可以提供氧从而把别的物质氧化的性质是氧气的氧化性，具有氧化性的物质可用作氧化剂。

注意：烟—大量固体小颗粒分散在空气中产生的现象；雾—大量小液滴分散在空气中产生的现象。

光—固体物质燃烧时发光；火焰—气体物质和容易汽化的物质燃烧时产生火焰。

镁条燃烧发出耀眼的强光；木炭在氧气中燃烧产生白光；蜡烛在空气中燃烧产生黄色的火焰，是石蜡汽化后的气体燃烧而产生的；铁丝燃烧没有火焰。

通过以上几个实验，我们可以看出，物质在纯氧气中燃烧比在空气中燃烧要剧烈，甚至某些不能在空气中燃烧的物质能在纯氧气中燃烧，说明氧气的化学性质比较活泼，同时也说明物质燃烧的剧烈程度与氧气浓度有关。

规律总结：上述这些反应的共同特点:①都是物质跟氧气发生的反应；②这类反应属于氧化反应；③生成物都是氧化物。

知能解读：（三）氧气的用途供给呼吸和支持燃烧。

冶炼钢铁（用纯氧炼钢，使生铁中的杂质氧化而除掉）；氧炔焰焊接和切割金属（乙炔在纯氧中燃烧，产生高温）；液氧炸药（将锯木屑等可燃固体用液氧浸泡后制成炸药）；是急救、高空飞行、潜水等的必备品。

Generally speaking, it is often used to describe anything from creative imagination, including works of poetry, drama and fiction.Then why read literature, since it is often imaginary and seems unconnected with real life?A lot of us re ad literature for enjoyment and relaxation. It’s always pleasant to read some interesting b ooks in our spare time. In a modern life full of stress, it is our common wish to read some imaginary works and look for relaxation from the stress in life.Reading literature is more than fun; it also allows us to get knowledge. As a general rule, literature represents a language of a people, and it often gives us an insight(洞察⼒) into the traditions, attitudes and values of the age in which it was written. Sometimes literature can even offer us new, creative ways to have a better understanding of the world. It introduces us to new worlds of experiences. We enjoy the comedy and the tragedy of poems, stories and plays; and we may even grow through our literary journey with books. At last we may discover meaning in literature by looking at what the writer says and how he or she says it. In some ways, we explore the human condition and analyze(分析) the way they think and feel the way they feel. Literature helps us think clearly and encourages us to open minds.So we can certainly say literature is of great importance to us.
