早上的城市朦朦胧胧地伸伸懒腰打个哈欠,发出了“噜噜”的声响,那一串一串的声响就像一对对打鼾声,又如一个个抱怨,厌烦的是三三两两的怨妇嗑着瓜子的骂街声,汽车吐着大汽“轰轰”的打屁声,工厂抽着雪茄的“突突”声,哪一阵一阵的声响,就如一堆沙尘,没灭了城市,埋灭了梦想。
唯有那小学生门清脆的读书声,才让城市在这个即将湮灭的寒夜安静的入睡——梦里,城市做了一个梦,它安居到了大自然,哗哗的流水声,动物们的唱歌声,踏踏的声响像轻快的音乐,伴着城市跳了起舞蹈,就这样跳啊跳,它跳过了山与水,跳过了美与丑,怨恨与和平,嘈杂安静,在梦里,城市经历、探索、发现了前所未有的美景,在梦里,一切事物化为美好,清水漂荡的“哗哗”声掩住了汽车“嘭嘭”的放屁声,小鸟“叽叽喳喳”的歌唱声埋没了工厂的“呼呼”抽烟声,街头的叫骂化声成动物们玩耍的嘻嘻声,城市不由赞叹:多美啊!不久,便沉醉于与动物们欢声笑语的梦幻中,不知道过了多久城市醒来了,身边没有了轻快的音乐,只有一片嘈杂,刺耳的汽车响铃撕破天空,唉,这种苦日子什么时候才结束啊!
也许,这美妙的梦境只有城市会回忆,因为这个梦永远是城市渴望的声音!
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?
无论你在城市的哪一个角落,都能听见一种声音。那就是汽车的轰鸣声。这种声音,不管是老人少年还是婴童都有一定的伤害。
我想大家还不太了解噪音吧!那就让我来告诉你。噪音分为三种,第一种是建筑噪音,建筑噪音是阶段性的,因为只在白天开工。第二种是交通噪音,持续的时间会比较长。第三种是生活噪音,一般是有太大的电视、音乐声音等等。
音量的单位就是分贝,英文就是DB。下面就让我来告诉你生活中的声音的音量是多少:1分贝是我们刚刚能听得到的声音;20分贝以下可以算是安静;20-40是人与人之间的轻声细语;40-60是正常交谈;70分贝以上就算是很吵了,这时的声音就会损害听力了。90分贝以上听力受损。如果你在100-120分贝的空间中待上一分钟人就会暂时失聪。有时会需要很长时间才能恢复。
在噪声的环境里,会影响我们的正常生活和工作。长期的噪声环境会使人患多种疾病,使人烦躁不安,内分泌失调等等。
噪音可真是太可怕了,所以请大家不要制造一些噪音。对了还要告诉你们一个小秘密,可以在就家里养一些花草,这样可以消除一些噪音哦!!!~~~
They are afraid we will have accidents as the river has no safty measures.
So, of course, we should go to the river for swimming. It may takes our life for no reason.
It is very cruel. Sometimes we can hear the news that someone die because of swimming in the river.
If we want to swim, we can go to the swimming pool with adults. This is safe. And we can also ask a teacher to teach us. Just remember, do not go to the river to swim secretly. We should take responsibility for ourselves.
大人们总是警告我们不要要江河水库游泳。他们担心我们会发生意外,因为江河水库没有相关的'安全措施。所以,我们当然不能去江河水库游泳了。这很有可能会突然就夺走我们的生命,是很残酷的。有时候我们也会听到一些新闻说有人因去江河水库游泳而丧命。如果我们想要游泳,我们可以在大人的陪同下去游泳池游泳。这样是安全的,我们也可以请教练教我们。一定要谨记,不要私自到江河水库游泳。我们要对自己负责任。
