水,是人类的生存之本,只有保护水源,人类才能生存。今天就来看看我发明的储水神器,水源收集器吧!
水源收集器的模样很奇怪。头上顶着一把倒立的“大伞”,身上披着一件会变色的“衣裳”,脚上还有两个“大莲蓬”呢!
它的功能也很全面。一到下雨天,首先工作的是中间的屏幕显示器,它会根据雨量大小,分别显示红色、黄色、蓝色。上面的“大伞”可以接住足够的雨水,大伞的末端还有水源净化系统,可以进行过滤、除尘、消毒。经过这样一个过程,水会变得非常清澈,旱灾的`时候,就可以通过管道把水直接输送给每家每户,大家就直接饮用了。很多人都很好奇,纷纷前来观看我这个储水神器呢!那两个“大莲蓬”是干什么的呢?原来储存的水不仅可以给人饮用,还能浇花浇草呢!水会从“大莲蓬”里面冒出来,就像两把大花洒一样,均匀地喷洒在植物身上,植物可以尽情地吸收水分。就在这一刻,花儿更艳了,草儿更绿了,到处都是一幅生机勃勃的样子。
如果不保护水源,地球上的最后一滴水就是人们的眼泪。为了更好的明天,让我们珍惜水源,共同打造这台储水神器吧!
nowadays, we can see some boys and girls who live in a small world of their own. they bury themselves among books and are proud of themselves. they think that it will make them lose their face if they do housework for they often think themselves very noble.
these young people are wrong. in my opinion every student should have a knowledge of housework. after all, they will have a family of their own, and they should do their part in keeping a good home. boys should also learn to do housework, for what will they do if they remain single? though not all boys remain single,yet they will be very helpful in the family if they know some housework. anyhow they will not lose anything, but, on the contrary, they will gain something useful.
for what i said above, we can find some eamples of our fellow-students studying abroad. all young men do housework as girls do. someone would argue that we can employ servants. this is true.however, what shall we do if the servant leaves us and all things are left to ourselves? we just cannot leave our clothes as they are and let worms and ants eat them up. and what can we do it we go and study in a foreign country where servants are out our means to employ? we must work for ourselves. why not start to learn to do housework now or else it will be too late? everyone should learn to do housework. what do you think about my idea, boys and girls?
Giant Panda is our national treasure, the state can be said for the protection of giant pandas put a lot of human and material resources giant now has been the world's people the protection and care, which is a good thing, of course, the Tibetan antelope as the country's animal protection , The National People have been recognized, however, this tiger? The poor will be extinct Siberian tiger who is going to have a genuine concern and care a little bit?
According to statistics, the Siberian tiger left at present, less than 20, still such a small number of these survive, has had imagined. Two years ago, in the mountains of Huanren, Liaoning found to be a man to die under the presentation of the Siberian tiger, from this we can see that the above countries and the people of the importance we attach to it, this first Manchurian tiger is actually how the dead do not Conclusion, and the other is only from the northeast where hu came to the place where the wonder and the third is the matter did not rise to the national media in particular. This really puzzled the other person you! Is it really the other tiger who fear love is not worth it, it really fate of the Siberian tiger so?
Towering mountains should not unique to human beings, should not have dense forest unique to human beings, rivers clear this should not be unique to human beings, the Siberian tiger survival of this nature should not be unique to human beings. Siberian tiger to the left of a piece of heaven and earth to survive it, the High IQ is the human species, there are still ways to leave that piece of local survival, and the tiger have to leave that piece of the local dead; you save tigers, is the human population control, engage in Family planning, and the Siberian tiger is scarce Rending it! Now we can hear the cries of tigers in the future even the Siberian tiger can be heard the cries.
