程灵素....

看完飞狐外传的第一遍,真实感觉最后一章是多余.本来一切都好好的结束了,却在最后弄如此之大的波折.阿金啊,你何苦呢?
在我看来,程灵素的智慧和赵敏应该是在伯仲间了.其实自从胡斐答应了帮她做一件事,她便应该好好的打算把握.但她确实爱得太无私了,太为胡斐着想,以至最后以自己的生命去换自己对胡斐的爱.
其实,此时袁紫衣早已出家,若在那九年中她能与胡斐在一片'世外桃源'里一起生活,天天能看到自己心爱的人,也何尝不是一件快乐之事.她那样聪明,连师傅无嗔都没种活的七星海棠也能种活.并且用九年时间去探索医治胡斐体内之毒,很难说没有奇迹发生.
断一只手有什么要紧的,杨过断了一臂,仍能练成绝世武功,报仇之事迟些又能怎样?
程灵素,她为什么要爱得这般的善良,若是不答应与胡斐结为兄妹,若是硬要胡斐来爱自己,若是胡斐坚持同生共死,也不至于一个人在路上那么的孤单....


不过还好,现实生活中是没有她这样的人的,起码我是永远不会遇到.

Modern nuclear structure theory is rapidly evolving from macroscopic and microscopic models of stable nuclei towards vast regions of short-lived nuclei far from the valley of beta-stability. One of the central goals of theoretical nuclear physics is to establish a relationship between low-energy, non-perturbative QCD and the rich phenomenology of nuclear many-body systems. An extensive study of microscopic nuclear energy density functionals has recently been initiated based on effective field theory methods and principles of density functional theory. Guided by two closely related features of QCD in the low-energy limit: a) in-medium changes of vacuum condensates, and b) spontaneous breaking of chiral symmetry; a framework of relativistic energy density functionals has been developed and applied in studies of ground-state properties of spherical and deformed nuclei. It has been demonstrated that a self-consistent Kohn-Sham density functional approach to nuclear dynamics, constrained by the chiral symmetry breaking pattern and the condensate structure of low-energy QCD, can provide an accurate description of nuclear matter, bulk properties and excitations of stable nuclei and exotic systems far from stability.

Issues around climate change have aroused international attention recently, which continuously reverberate across the globe. China, an old-line country, suffered a lot in the winter 2008 from climate change. The devastating snow storm was reported as the heaviest in the recent 50 years(Lai,2008). During this natural disaster, China's transport and energy systems were severely damaged, causing "hundreds of thousands of people stranded during the peak travel season"(McGregor,2008). The power grid of Chenzhou City, Hunan Province in southern China, was completely down in this snow storm. According to the Civil Administration Department of China, the direct economic loss was 31.1million dollars, and 25 million people were affected(McGregor,2008). From this point, snow is no longer scenery in winter, but a symptom of a disaster resulting from climate change. Moreover, other potential effects of climate change are also radically serious.

Firstly, bio-diversity in China is being severely affected by the climate change. IPCC (Wikipedia) has published many articles on the relationship between climate change and ecosystems, which reveal species' consistent responses to warming trends. In the trend of global warming, some certain kinds of cold-tolerant animals and plants are already in danger and more are under threat, while the majority of insects and bacteria are in prevalence in higher temperature. This situation will surely lead to a bio-disaster if nothing is done, especially in China, whose bio-diversity has already become quite vulnerable after a long time of large scale exploitation. According to Bhatti (2005), the number of mosquitoes is in a rising trend annually, while its natural enemies, like frogs and swallows are declining. If this trend continues, China will pay a lot more to deal with it later.

Secondly, climate change may contribute a lot to sandy desertification in China. As predicted in 2001(He,2001), the temperature in a majority of places in China will rise by around 1 degree, amount of precipitation will drop by 5 percent, and the main trend of the climate in China will be dry during next ten years. Less rainfall and higher temperature will certainly accelerate the land desertification, which was started by overwhelming logging and destruction of plants and forests. According to the data collected by Land and Resources Bureau of China (He,2001), the sandy land, originally 6.67million square kilometer, almost doubled in 1985, and now, it is estimated to spread at 5 square kilometer per day. These statistics may sound surprising, but if a person walks around China, he or she will be astonished, that some rivers are drying up, lands become bald, even the "golden farm land" in the west Chengdu now has lost its fertility and moisture, becoming too hard to grow any plant. In all, if the Chinese government does not make real effort to fight, climate change will soon drive the whole green lands to desert.

Last but not least, the huge financial losses are also the worst effects caused by climate change. Xinhua news agency published a report about the Chinese government dealing with land desertification. It said that 30million dollars are put in every year, but it is far from enough. Take the snow storm this winter as an example: hundreds of millions of dollars are used to rescue people and repair the broken facilities, but the indirect financial loss is uncountable. Compared with the circumstances 20 years before, millions of kilowatts of electricity are consumed to warm up the cold areas and cool the hot areas. Furthermore, according to He(2001), the source of Yangtze river is drying up, the volume of water has decreased by 20%, and the lakes along the rivers have shrunk back about hundreds of meters. If this trend is not stopped, the past investment on the billions-dollars worth Three Gorges Dam will be wasted.

From what have been illustrated above, an obvious conclusion can be drawn that the potential bad effects related from climate change are devastating to China. Efforts should be made immediately. Otherwise, much will have to be paid to maintain it as a place to live.

Zero waste V.S landfilling

Nowadays, the concept of zero waste is popularizing around the globe, giving people a light for reducing rubbish. Zero waste is quite useful in many aspects compared with the traditional landfilling.
Firstly, as the definition of zero waste suggested, it does not sacrifice land to the rubbish. In zero waste, people use the things which are recycled, meaning that even a useless thing can be made into another useful thing. As a result, materials are saved, at the same time, the land is saved too. However, by the conventional landfilling, large amount of land is wasted and polluted. This situation is extremely unacceptable in this high population world today. In contrast, material recycling can also reduce the exploitation of new natural resources, which come from the used things in zero waste. Meanwhile, the emission of greenhouse gas and environment pollution related to the exploitation of the natural resources like drilling and milling can be significantly deducted. Furthermore, the time value and economic value should be taken into account. Through zero waste, the land can be used in other much more efficient ways. Forests can be saved and replanted, protecting bio-diversity and producing fresh air as well. Nevertheless, landfilling can only lead to useless land lasting for centuries.
From what has be well illustrated above, we can safely say that the concept of zero waste is environmentally friendly, and evidently better than the traditional way we deal with rubbish.

After reading "Saving Nature..."

After the first time reading this article, I felt that the author was just unashamedly finding excuse for the demolishing exploition on Earth.Every result must has its causes. However, we are just human-beings,not god.We can not know everythings before hand.Although scientists can predict what is going to happen at what time and what place,but the accuracy of such prediction has its limit.
When people started to log forests, they did not know the soil may be flowed away, they did not know the bed of rivers may be raised up.When smart people developed engin, they didnot know the atmosphere may be poluted so much, they did not know countries may be involved into wars for oil.
Standing on the opporsite side to the author, I insist that human should leave the unexploited area on Earth as much as possible.If only thinking for human, human is more likely a blind,things will go wrong much more quickly . Giving people a better standard of live should not rely on using the untouched nature,digging deeper into the earth, but introducing new life style, new concept and new technology.
Additionally, though we just think for ourselves,the untouched places may be the last place for human to rest, if the movie "water world " become true one day in the future.

where has the fertile land gone??

According to a research about farming lands in China, five billion hektare lands are becoming sandy every year, 4 million hektare forest are vanishing every day, thousands of ton fertile soil are washed away every second.

This sounds astonishing, but it is true in China today, and the causes are evident- the excessive exploition of the environment and pollution.

To solve these problems, the Chinese government should firstly protect forest. As science books write, every tree can hold soil of three times its weight. Trees are the most efficient way to keep the soil from washing away.To get rid of the illegal usage of forest, the government should put every effort in it, and punish the suspects as strict as possible.

Furthermore, new power system should be adapted as quick as possible. A coal power station uses thousands of coal every day to burn. As a result, acid rain forms.This in turn destroy the forest in a farely large scale.Obviously, traditional power station should be replaced if the government want to protect the forest.
