英文:
Now, I have heard in the advocacy of urban low-carbon life, I gradually some understand. Me start the "low-carbon life."
First, low-carbon way of life, that is, pay attention to the details of life saving and cost reduction. Apart from homework to turn on the lights, the rest rely on things outside the window lighting to help solve the problem. Because of our large living room, the window of shone lights can be seen prominently in all indoor, meal, really like a table "candlelight dinner", and it was a great light, "natural light ah!"
As long as I wash players, they regarded the tightly screw the tap, allow the water to "escape" out, so I can relax. But I worry about Mom and Dad will do well into the toilet every time to see Mom and Dad's hands and let it close all the taps, I am very happy, I hope the "carbon family" will do better.
Stood a mess of things in the fridge, mom said he was a waste of electricity, I had an idea, come up with a clever move: So I picked up before the mountains of cardboard, put it into a box of varying size, the above paste on the various categories of signs, then, to organize by category, soon, the refrigerator becomes clean and tidy, new look, a neat place to see things. Thus, not only helped us, but also save electricity.
Original, electrical drives, even the little cell phone battery when plugged in the outlet would be terrible emissions of carbon dioxide, as long as the fully charged battery should be removed promptly. I thought, only carbon dioxide, car exhaust, coal combustion emissions of these will be, did not expect everything in life has a weak "C" in the violation of our lives and our planet.
When I saw my mother washing the barrel should throw away, I was to go to stop. I will put it into a small trash can, some like a doll, pink Doodle face, very cute! Some of it's like a small animal, vivid, and really like a beautiful "scenery"!
When night fell, after dinner, roadside neon glory to add a night, Dad always at home all the lights are turned off, leaving only a pitch-dark in the dark, and then, lying on the windows, enjoy the scenery while the roadside, while singing a song: "The Moon Represents My Heart ... ..." It's tone deaf, a mess.
Growing Flowers is a loving mother. House spider plant, ivy is green all year round. In each scorching summer, my mother always put flowers move house, we looked at the green, allow smoking that are green, heart suddenly felt faint trace of coolness, there is a good air is seductive, really kill two birds with ah!
Such a good home environment, and full of innovative small joy.

现在,我听到了城市在宣传倡导低碳生活,我渐渐有些懂了。我开始了“低碳生活”。
首先,低碳的生活方式,就是在生活的细节上注重节能减耗。除了做作业必须开灯之外,其余的事情都靠窗外的照明灯来相助。因为我们的客厅大,窗外的照明灯照进来都可以醒目地看到室内的一切,吃饭时,真像一桌“烛光晚餐”,这真是一大盏“天然的灯啊!”
只要我洗好手,就都把水龙头拧的紧紧地,不让水“逃”出来,这样,我就可以安心了。但我又担忧爸爸妈妈会不会做好,每次看见爸爸妈妈进洗手间洗手并顺其自然的把水龙头关紧,我十分高兴,我希望 “低碳家庭”会做的更好。
冰箱里放着乱七八糟的东西,妈妈说很浪费电,我灵机一动,想出了妙招:于是,我就拿起以前堆积如山的硬纸板,把它做成一个个大小不一的盒子,上面贴上了各种分类的标志,然后,按分类去整理,不一会儿,冰箱变得又干净又整洁,焕然一新,一眼就目睹摆放整整齐齐的东西。这样,既帮助了我们,又节省了电。
原来,电器开着,就连小小的手机电池在插座上插着时都会排放出可怕的二氧化碳,只要充完电就应该将电池立刻取下。我本来以为,二氧化碳只有汽车尾气、煤炭燃烧这些会排放,没想到生活中处处都有微弱的“碳”在侵害着我们大家的生活和地球。
每当我看见妈妈要把洗衣粉的桶扔掉时,我会上前去阻止。我会把它做成一个小垃圾桶,有的像个洋娃娃,粉嘟嘟的脸,可爱极了!有的又的像只小动物,活灵活现的,真像一道美丽的“风景”!
当夜幕降临,晚饭过后,路边的霓虹灯为夜晚增添了一份光彩,老爸总是把家里所有的灯都关掉,只剩下一片伸手不见五指的黑暗中,然后,趴在窗户上,一边欣赏路边的风景,一边唱着一首歌:“月亮代表我的心……”真是五音不全,一塌糊涂。
养花是妈妈的爱好。家里的吊兰、常春藤一年四季都是绿意盎然。在每个炎炎的夏日,妈妈总会把花搬进家里来,大家看着那些绿色,允吸这那些绿色,心中顿时感觉丝丝的凉意,有了好空气又养眼,真是一举两得啊!
这么好的家居环境,并且充满了创意的小欢乐。
(1)水能是可以从自然界中源源不断的得到的能源,故属于可再生能源;
(2)A、因为水的比热容较大,相同质量的水和其它物质比较,升高相同的温度,水吸收的热量多,所以用水冷却汽车发动机,故该选项符合题意;
B、寒冬季节,放在室外的水缸会破裂,其原因是缸内的水结冰时体积膨胀,同时缸本身遇冷收缩造成的,故该选项不符合题意;
故选A.
对于A选项是利用水的比热容最大的特点,因为水的比热容较大,相同质量的水和其它物质比较,升高相同的温度,水吸收的热量多,所以用水冷却汽车发动机.
(3)内燃机的一个工作循环有四个冲程,即吸气冲程、压缩冲程、做功冲程、排气冲程,在压缩冲程中,活塞由上向下压缩气缸内的空气,即对空气做功,使得空气的内能增加,温度升高,这是通过做功的方式改变了气缸内物质的内能.
故答案为:(1)可再生;(2)A;对于A选项是利用水的比热容最大的特点,因为水的比热容较大,相同质量的水和其它物质比较,升高相同的温度,水吸收的热量多,所以用水冷却汽车发动机;(3)四个; 1; 做功.
(1)水能可以重复使用,故水是再生能源.
(2)在江河上修筑拦河坝,抬高坝内水位就能增大坝内水的重力势能,因为高度增加.
(3)水具有比热容大的特点,冷却汽车发动机,育秧时,为了防止霜冻,常在傍晚时向秧田里灌水等都是利用它这一特点,而
寒冬季节,放在室外的水缸会破裂,这是应用水结冰体积变大.
故本题答案为:(1)可再生;(2)重力势;(3)B.
