篇一A Busy Day
Today is Monday; I wake up at 6 o’clock in the morning. Then I have my breakfast at home and take the subway to school. I am quite excited about this day, because our chemistry teacher will teach us to do an interesting experiment. This experiment is about how to create soap. Last week, the chemistry teacher promised that we would have something fun in this week. Making our own special soap is the mission in this class.
When the experience begins, the whole class is very exciting; we mix the oil, water and lye. You need to be very careful, because the lye is harmful to the skin. Then we will stir the oil and lye for about ten minutes, the chemistry reaction will make the liquid into solid. Then the soap comes into being. Although the process is tired, we have a lot of fun. The most important thing is we learn how to make soap. The time passes so quickly, we feel very busy but learn a lot of useful things.
今天是星期一,我早上六点就起床了。再吃过了早餐之后,我搭地铁去学校。对于今天要做的事情,我很兴奋。因为我们的化学老师要教我们做个有趣的实验。这个实验就是如何制作肥皂。上个星期,化学老师向我们保证这周会做个有趣的实验,而创造出属于自己的一块肥皂就是这次课的主要内容。
当实验开始的时候,整个班级都很兴奋。我们把油、水和碱液混合在一起。你必须非常小心,因为碱液会腐蚀皮肤。然后我们就开始搅拌液体。大约10分钟过后,发生的化学反应就把液体变成了固体,肥皂就形成了。虽然这个过程很累,但是我们得到了很多乐趣。最重要的是我们学会了如何制作肥皂。时间过得太快,我们感觉很忙碌,但也学到了很多有用的东西。
篇二Low-carbon Lifestyle
Now we are facing two problems of global warming and a shortage of natural resources, both of which are getting more and more serious day by day. Thus, it is important for us to promote a low-carbon lifestyle.
Low-carbon lifestyle covers many aspect of our life like transportation, traveling, home-heating, and so on. In order to promote a low-carbon life, some plans must be carried out as follows. Firstly, don’t waste any electricity and water. Remember to turn off the lights and water taps unless we use them. Secondly, we had better take the subways or bus to work, so as to reduce the emissions of carbon dioxide. Thirdly, we should use cloth bags for shopping instead of plastic bags, and use recyclable bowls and chopsticks instead of disposable ones, for it can not only save resources, but also reduce pollution. What’s more, it is of great significance to plant more trees, since trees can balance the carbon dioxide emissions.
In a word, if we live a low-carbon life from now on, we will have a better environment and more resources left for our descendants.
如今我们面临着两大环境问题:全球变暖和自然资源匮乏,且情况日益严重。由此可见,提倡低碳生活的重要性。
低碳生活方式包括了我们生活的很多方面,比如交通、旅行、室内取暖等。为了促进低碳生活,我们应该采取以下的行动。首先,不要浪费水电。要记得随手关灯,用水完后随手关闭水龙头。其次,我们最好坐地铁或是公交车上班,这样可以减少碳排放。第三,我们购物时应该用布袋替换塑料袋;使用可循环利用的碗筷,不使用一次性用品。因为这样不仅节约资源,也减少污染。此外,大量植树也很重要,因为树木可以平衡二氧化碳排放量。
总之,如果我们现在开始低碳生活,我们将会拥有跟美好的环境,还为我们的子孙后代节约资源。
