菊花
我喜欢的花有很多，有清新的百合，雪白的茉莉，素雅的水仙，鲜艳的玫瑰，也有代表爱的康乃馨……它们有优雅的气质，舒适的芬芳，但我最喜欢的还是那遇见风霜雨雪绝不低头的菊花。
菊花与梅，兰，竹合称为“四君子”，别名黄花，属菊科，是宿根花卉。菊花盛开后，清香四溢，它的花瓣如丝，如爪。一层层的花瓣好似是在漆黑的天幕中绽放一颗颗明亮的烟花，它的花瓣稍向外翘起，美丽极了。菊花的颜色也很多，或黄，或白，或赭，或红，种类繁多。
菊花的品种更多，按时可分成九到十月开花的早菊，十一月份开的秋菊，十二月开的晚菊，此外还有五月菊，七月菊，八月菊等。菊花的花型美不胜收，有的像散开的烟花，有的像蛟龙的爪子，有些小菊花则像小朵的荷花。
菊花的习性是喜阴耐寒，寒冷的冬天时，许多花都凋谢了，只有菊花坚强的盛开着。
菊花的观赏价值很高，而且还可以泡茶。菊花茶清热去火，还可以对外伤起到消毒作用。菊花不仅观赏价值高，可以泡茶，还可以入药，菊花做的中药可以缓解咳嗽，也可以治喉咙痛。
我国是菊花的故乡，种植历史相当悠久，早在三千多年前就有相关记载。许多文人雅士曾写下过许多赞颂菊花清丽高雅，不畏寒霜的诗句。如古文中的“菊花性耐寒，严霜既降，百花零落，唯菊独盛。”大文豪苏轼的“荷尽已无擎雨盖，菊残犹有傲霜枝。”
我们从菊花身上学到了坚强不屈的精神，我喜欢菊花!

保护野生动物
With the development of society,there are more and more problems brought to our attention,one of which is that wild animals have no place to survive in the 21st century.Some people think that the protection is a waste of resource.From my point of view,I disagree with this statement for some reasons below.
Firstly,the animals and human beings are creatures created by God.We can’ behave like barbarians and destroy the environment.We need places to survive and so do animals.Secondly,there are a lot of species of animals on the earth.They are just like our neighbor.For example,in my childhood,I went to my grandparent s’ home in the countryside .There is a forest near the house.We met a lot of little wild animals there ,such as,monkeys,snakes,rabbits and so on.However,there are a lot of people who may agree cut down the forest.
From my angle,we,human beings,can’t deprive the survival rights of animals.On the contrary,we have to protect them from extinction.Just imagine how horrible the world would be if human is the only creature in the world.Hence,the government should ecate people to preserve and protect our neighbor,natural wild animals

学校应该要用游戏来教学,不知道这样的文章你要不要
http://www.computerweekly.com/Articles/2010/09/10/242705/Report-urges-national-curriculum-include-computer-games.htm
Schools should introce computer games in class to update the IT curriculum and help drive young people into IT careers, according to experts.
The Council of Instry and Higher Ecation (CIHE) have released a report claiming the IT curriculum is preventing IT instry growth and should be changed to be made more relevant to school children. This includes teaching computer principles relating to computer games.
"The current curriculum concentrates on word processing and office proctivity tools, but fails to ecate students about the vital computing principles which underpin games and internet services," said the CIHE in its report.
Bill Mitchell, director of the BCS academy for computing and member of the CIHE report task force, said: "For many years the emphasis has been on training children how to use technology. But they also need to understand computing. Learning about Microsoft Word, Powerpoint and Excel are all important but if that's all children learn about, they will get bored. Computer games are incredibly motivational and embody the fundamental principles of computing."
There has been growing concern about IT ecation from instry experts as the drop in numbers of young people taking IT-related courses looks set to fall short of demand for IT skills.
The Department of Ecation said it is reviewing the curriculum. "The new government has come in and feel [the curriculum] is restrictive and isn't teaching kids what they need for the real world," said a spokesman.
