了解班级课外阅读情况

get to know about the nature.

Do you want to know about my family?

I always feel tired after eight classes a day,so my dream school starts at 8:30 a.m.and ends at 3:30 p.m.There are three lessons in the morning and two in the afternoon.We can choose our favorite lessons to learn.We can spend more time doing some outside reading.The students do after-school activities for one and a half hours every day.We needn’t do a lot of homework.We are all happy to stay at school.
Besides that,my dream school looks like a big garden.There are many kinds of flowers around the modern buildings.Sweet perfumes are diffused all around.If I want to have a rest,I can lie on the grass,listen to music by the lake or look out at the flowers from the classroom windows.
The teachers here are kind and helpful.They are not only our teachers but also our good friends.The students are polite and friendly.We all know how to keep our school clean and tidy.There is no litter around the campus.
I love my dream school.We will grow up to be happier there

地球是太阳系从内到外的第三颗行星,也是太阳系中直径、质量和密度最大的类地行星.地球已有44～46亿岁,有一颗天然卫星月球围绕着地球以30天的周期旋转,而地球以近24小时的周期自转并且以一年的周期绕太阳公转.

生物入侵者：alien invasive species
定义入侵物种的标准：
1）通过有意或无意的人类活动而被引入一个非本源地区域；
2）在当地的自然或人造生态系统中形成了自我再生能力；
3）给当地的生态系统或地理结构造成了明显的损害或影响；
外来入侵物种,是指那些出现在其过去或现在的自然分布范围及扩散潜力以外（即在其自然分布范围以外或在没有直接或间接引入或人类照顾之下而不能存在）的物种、亚种或以下的分类单元,包括其所有可能存活、继而繁殖的部分、配子或繁殖体.外来入侵种是对于一个生态系统而言,在该生态系统中原来并沿有这个物种的存在,它是借助人类活动越过不能自然逾越的空间障碍而进来的.人自然情况下,山脉、河流、海洋等的阻隔以及气候、土壤、温度、湿度等自然地理因素的差异构成了物种迁移的障碍,依靠物种的自然扩散能力进入一个新的生态系统是相当国准的.虽然也有由于气候和地质构造变化,使动物、植物或病原体进入新的系统的情况,但更多的却是由于人类活动而有意或无意地导致了越米越多的物种迁移.
外来物种的入侵与生态系统的建立、稳定及演化的机制是分不开的.一个外来的物种被引人到一个新的平衡的生态系统中后,可能因不能适应新环境而被排斥在系统之外,必须依靠人类的帮助才能生存；也可能其恰好适合当地的气候和土壤条件,并且新的坏境中没有与之抗衡或制约的生物,此时,这个外来种就成为真正的入侵者,打破生态平衡,改变或破坏当地的生态环境,成为外来入侵种.
当外来物种在自然或半自然生态系统或生境中建立了种群,改变或威胁本地生物多样性的时候,就成为外来入侵物种.
