夏日的酷暑,冬日的寒冷,我不禁想起了家里的那盆仙人球,它直径约7厘米.圆圆的球体上披着一件绿外衣,绿外衣上还均匀的分布着小绒毛,绒毛旁还有短小的刺,这样那样的看,都是那样的可爱.
还有一个惊奇的发现,仙人球的生长速度非常缓慢,一年才长一厘米呢!
夏季来临,要保持土的湿润,不要过干,否则易晒死,若非常热,可放入冰箱内,箱内温度应保持在13度到15度.而入冬以后,应绝对禁止浇水,应保持盆土干燥,湿度不低于2度到5度即可安全过冬.
仙人球一般一年开一次花,开花季节大多在夏季,花朵谢了,会长出花果,花果内包的是种子.一两个星期内,花朵就谢了.绽开的时候是那样多姿,凋谢后也不改本面.
伴着这一切的一切,都变了.仙人球,每个家庭都可以准备一个,既美观,又可以净化环境!

1、菠萝的形状是圆柱形的,大小跟瓜差不多在.它的"头顶"上有着几片狭长的叶片,叶片的边缘有些细小的刺.真像个扎着瓣子的小姑娘.菠萝的皮很厚,也很粗糙,就像盔甲似的
2、还未熟透的菠萝是青绿色的,味道十分苦涩;熟了的呢,则是黄中带绿,味道酸中带甜.
3、用刀子把菠萝皮削开,就会看到黄澄澄的果肉.你如果闻一闻,一股清香就会直窜你的鼻孔,真让人垂涎欲滴.将削好的波萝泡入盐水中就可以吃了.你若切一块尝尝味道,你一定和我一样还没到嘴巴里,口水就不知不觉地流了下来.你轻轻咬一口,菠萝的汁液就会溢满了嘴巴,酸酸甜甜的味道好极了.

我说一下中心思想和主题
主题你可以虚构
写一个人的梦想如何开始,如何发展,如何结束
从每一个阶段描写他的内心想法和遭遇
开始的时候你可以写他很不顺
中途你可以写他很顺很走运
结尾你可以写他的梦想完成了大半,尝到了甜头,却最后落到失败的结局
最后,他懂了,他的梦想其实已经实现了
那就是他曾经拥有过为梦想奋斗的记忆,无论是开始或是结局,都是他梦想的一部分
你若有很好的文字功底,还可以更好的发挥

3、怀特老师通过一堂关于”凯特“的课,告诉学生一个道理,不能轻信权威.
4、怀特森老师是一个教学独特,教学有方的人.他用出乎意料的方法培养学生独立思考、独立判断、勇于向权威挑战和对科学的怀疑精神.也表明了怀特先生热爱学子们的本质.怀特森先生让我还有我的同学明白了一个重要的道理：不要迷信书本,也不要迷信权威. 书本、权威,代表的是已有的、被大多数人认可和接受的知识.怀特先生的两个“不要迷信”强调的是一种怀疑的精神,强调要通过独立的思考去获取知识.

童年时光
从出生的那一天起,
我就用彩笔在洁白的纸上,
勾勒我的童年时光.
我用粉色添涂欢乐；
用蓝色丰富想象；
用黄色表现稚气；
用绿色描绘梦想.
最后,
我还要用黑色来书写悲伤.
我无忧无虑地勾勒着
多彩的童年时光.
挥手别去了,
那充满稚气的孩童时代,
时间带领着我不断成长.
真希望河水向着反方向流淌,
带我找回那久别了的
童年时光.[/

你是完成牛津六年纪练习册吗?

1.托物言志的作文
那棵树
十几年的经历让我不禁觉得,本该精彩的人生却淡而无味.每一天都在重复着同样枯燥的事情,让我厌烦.
经历过几次不顺心的事,我开始想逃离这尘世.
我对母亲说：“我不想再这样下去了.再多的努力看来也只是徒劳,那么多人在我之上.我不如返璞归真,学习古人,过隐居的生活.”母亲没有说话.过了几天,母亲带我来到一座山前.那是一座我不知名的山,虽算不上高,却可用险来形容.我望着母亲,猜测着她的意图.
“你看到那棵树了么?”母亲指了指山崖.我抬头望去.陡峭的山崖间,赫然有一棵树,似已被山崖的细缝挤得弯了腰,却不乏生机.
“嗯,看到了.那是······”
“走,我带你上去.”母亲拉着我,寻了一个较缓的山坡,一步步向上走.
看着母亲额头上的汗水,我虽不解她的用意,却告诉自己一定要走上去.山顶.这确是一个人迹罕至的地方.
母亲拉着我,来到了那棵树前.“你看.”我愕然.那棵树竟是从石头中生长起来的!
“这,怎么会······”
“你看,这棵树要生长,就必须穿透坚硬的岩石.你是个聪明的孩子,我想你会懂的.”母亲不再多说.我小心地俯下身子,看着山崖上的那棵树.它的根确是生长在岩石中,坚韧有力地向四周伸展,似乎要汲取周围所有可以利用的养分.
顿悟.
我回头看着母亲：“我懂了.要想在世间取得自己的一席之地,就必须努力克服所有挫折,顽强的面对人生.”
在这之前,还要先磨炼自己.有了真本领,才能克服挫折啊!”母亲满意的说.
“嗯,我再也不说隐居这种傻话了.”
回去的时候,我回头望了望那棵树.在蓝天下,它恍若一柄宝剑直插云霄.它在告诉我,它要和逆境作斗争.
感谢母亲让我见到了那棵树.感谢那棵破岩而出的树,它让我懂得,再难渡过的逆境,再难克服的挫折,只要顽强拼搏,它们最终只会成为成功路上的垫脚石,帮助我们登上胜利的顶峰.
那棵树,永远生长在我心中.

Win Competition of Environment Protection for Beijing
Although the 2008 Olympics are still three years away,another special competition has already started in Beijing.This time,the competitors are not the athletes from all over the world,but the people living in Beijing.The special competition is not held in a stadium,but in every street and every corner of Beijing.I suppose some of you may have already guessed what the special competition is.Yes,it is the competition of protecting our environment and creating a green Beijing for the 2008 Olympic Games.
Someone may ask who is our rival in this competition?The modern Los Angeles,the charming Sydney,or the historic Athens?No,none of them.The real rival is ourselves.It is our bad habits of neglecting to protect environment in our daily life.
Several years ago,I was very lucky to have an opportunity to live in the United States for about two years.I not only enjoyed the beautiful environment there,but also appreciated the American people's active way of protecting their environment.Now,whenever the environment protection is mentioned,a beautiful view of California will arise in my mind:white clouds flying across the blue sky,green grassplot sprinkled with colorful flowers and small animals playing happily among the trees.
I remember that at the beginning of my coming to America,I often went to my father's working place,the United States Geological Survey,to have fun.Each time I found a lot of people riding bicycles to their offices.Among the cyclists,an old man with white hair attracted my attention.Curiously,I asked my father," Why does the old man ride his bike to work every day?Doesn't he have enough money to buy a car?" Father laughed,"No,not because of money.Actually,he is one of the greatest scientists in the world.He can afford to buy a motorcade if he likes.He is just an environmentalist and usually doesn't drive unless going shopping,or in bad weather.In America,there are a lot of environmentalists,who actively protect their environment.For example,in Palo Alto city we are living now,there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars".
Later,I also learnt another interesting fact of environment protection there.In some states of America,in order to decrease air pollution,save energy and reduce traffic jams,state governments encourage people to take buses to work or to share a car among several people.They even set special "diamond lanes" in some main streets,which are only for the vehicles with 2 or more people.
The positive actions of American people and the effective measures the American government takes in environment protection fully won my respects and deeply affected my consciousness in environment protection.
When I was back in China,people often asked me:" What do you think of America?" I always bolt out:" Wonderful,especially the beautiful environment." Frankly speaking,after several years,the faces of my American teachers and friends have gradually faded away from my mind,but the blue sky,green grass and lovely animals in California often arise in my mind,and became my dream of visiting there again.
The 2008 Olympics provide us with the opportunity to publicize and practise environment protection in Beijing.Is it possible for Beijing to Is it possible for Beijing to become as beautiful as California?The answer is "yes",but the dream needs every Beijing citizen's full support and active moves to accomplish.
From now on,if every student who is driven to school can take bus or ride bicycle to school once a week,if every car owner goes to work in a car pool once a week,we can make a difference.If everyone can actively protect the environment in our daily life,the blue sky,green grass and lovely animals in California will appear in Beijing.
Tiny streams can combine into a vast ocean,small trees can together be an immense forest.Beijing is often described as a beautiful and aged picture.If every Beijing citizen adds a trait of green on the picture,the whole Beijing will become an ocean of green.Let us unite together to win the competition of environment protection in Beijing,and present the world a big gold medal.That is "Green Beijing,Great Olympics "
