在当今社会,人们生活水平越来越高,科技越来越发达,一些高科技也层出不穷,但是在生活中,有一些发明并不是十全十美,这些例子值得我们深思。
比如,我们生活中最常见的塑料袋,它之所以被誉为20世纪最糟糕的`发明是因为它虽然方便了人们出行,携带东西方便,但是科学家忘记了一点,在塑料袋由慢慢被人们接受到经常使用以后,是否能合理使用并且合理处置用过后的塑料袋。由于它不能被降解,导致环境污染,阻碍植物生长,给农作物带来了严重的减产。
最近,科学家发现了第八个大陆、那是由人们所用过的塑料袋被风吹到海里堆积而成!它们经过海水的慢慢腐蚀,演变成了新大陆!由此看来,并不是所有发明都是十全十美的,但是,为了避免对环境造成更大的伤害,科学家已经开始研制可降解的塑料袋,并且有限制的让人们使用塑料袋,让人们花钱购买塑料袋,提倡使用布包。
再例如,电池是18世纪的杰作,方便了人们储存电,储存电能大,并且能充分利用电,能够安全使用电。但是在当今,电池已经是一个重要污染源了,它如果被扔在地下就会引起大面积土地被污染,导致农作物死亡,造成农民不小的损失。因此,电
池这个发明也不是十全十美的。
所以,为了防止土地被电池所污染,人们开始建回收电池垃圾箱,开始回收利用电池,这是一种保护措施。另一种就是发明代替产品,不用电池也可以储存电,但是目前科学家还没有发明出来能够完全代替电池的产品。所以,未来等着我们去发明。
再比如,现在最新的发明——机器人,它们能帮助人类工作,能比人类工作效率高,既实用又方便,让人们的生活更轻松,减小压力。但是,一旦机器人进入市场,并且大量使用会造成什么后果?会使人类失业率增大,造成人类手工业退化。它是方便了人们生活,但是长期使用机器人会使人类社会慢慢停滞不前,所以,我们要合理的使用机器人,只让它们代替人类做一些对人类来说比较高难的工作,这样会更加加大对机器人的利用率,并且没有导致大批人员失业。
由此看来,当今最先进的发明——机器人,也有它的弊端,科技创新并不是十全十美的、我们在合理使用它们同时也要扬长避短,把科技创新的优点加大,缺点减为最小,使科技创新的利用率加强,逐步使人类社会提高。
同学们,让我们用勤奋的双手,智慧的头脑使自己成为未来科技的主人,努力创造发明,为人类社会做出贡献。
The Best Way of Traveling最好的旅游方式
People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.人们会乘坐飞机、火车、轮船、公交车去旅游。对于我来说,最好的旅游方式是暑假期间徒步旅游。
On a summer vacation I travel to refresh myself and to see the countryside. When I use my feet and walk on a grass covered path or among the hills I feel detached from the noise of the city and closer to the nature. And when I travel on foot I get more freedom. I can plan my own schedule. I can choose my own route. I can stop where I like. And I can see things and people that I might miss if I travel on a train or on a bus.暑假的时候,我通过旅游去释放自己和游览乡间。当我用双脚走在铺满小草的小径或山间时,我感觉(自己)远离城市的喧嚣,并且更亲近大自然。当我徒步旅行时我可以得到更多的自由。我可以自己选择行程。我可以自己选择路线。只要喜欢,我就可以停下来。而且我可以看到很多人和事,那些我可能乘坐火车或公车旅行而错失的。
When faster and more convenient ways for travel are becoming available, I still favor using my own feet. I get much pleasure from it. 当更快、更方便的旅游方式变成通用的,我仍然支持用自己的双脚(旅行),我从中得到了许多乐趣。
During the summer vacation, my father and mother took my sister and I to Dalian. My brother and I had a good time at the high tide adventure palace in Xinghai Park.
My sister and I sat on the adventure boat excitedly and began to move forward. The ship flashed along with the speed of the water. Suddenly, the ship turned a bend, entered a dark cave, and there was no five fingers in it, and the horrible bats sounded. Our boat rose, seven or eight meters high, and immediately swooped down to the top, splashing four or five meters of water. The ship continued to move forward, and there was a faint light in the depths of the cave.
When the boat approached, we were surprised to see that many dinosaurs were realistic. If you don't look at it carefully, you really need to be scared. These dinosaurs were all big mouths and looked terrible. The water is speeding up, a sharp bend, and we are coming to the "ape man world". In the dense forest, we can see the vivid figures of our ancestors. Some of them sit on the grass, watch around a round object, hang on trees, and wash their faces and feet at the water. Suddenly, a huge crab lay on the water and blocked our way. The smart elder sister just put her head down and just passed. I also lowered my head and tried, but no way, I squatted down in the bottom of the cabin. Hey, it was really successful.
Just through an obstacle, suddenly the water stopped, so we had to row ourselves by boat. My sister and I worked together and rowed vigorously. After about 20 minutes, we reached the finish line and ended this exciting and interesting adventure tour.

My preference depends on the purpose of the travel. On a summer vacation I travel to refresh myself and to see the countryside.

And I can see things and people that I might miss if I travel on a train or on a bus.我的偏好取决于旅行的目的.。在暑假我旅游是为了消除疲劳并欣赏乡村美景。当我沿着河流或在群山之间走在一条青草覆盖的路上时,我觉得我远离了城市的喧嚣、亲近了自然。徒步旅行,使我很自由。我可以自己安排行程。可以选择我自己的路线。我可以把车子停在我喜欢的地方。而且我可以遇到那些坐火车或公共汽车会错过的人和事。

Today, as people live a better life, they chase for more enjoyment.
We can see from the news that when the holiday comes, there are so many people gather in the scenery site. People like to travel today, they can take a plane, take the bus or even take a bike. On my opinion, the best way to travel is by train.
First, it is very cheap. Compare with other ways, such as plane and bus, train is less expensive, people can save a lot of money.
Besides, taking the train is much safer.
People don’t have to worry about crush, which is more happen in the plane or bus. Second, we can enjoy the scenery in the train.
Though the train is very slow, we can have a good sight of the beautiful scenery, when we go to Tibet, we can see different colors and different mountains during the trip. Taking the train is the best way to travel.
今天,随着人们过上更好的生活,人们追求的娱乐。我们可以从新闻上看到当节假日来临的时候,很多人聚集在景点。现在,人们喜欢旅游,他们可以坐飞机,坐巴士甚至骑单车。在我看来,最好的旅游方式是坐火车。第一,这很便宜。和其他方式,如飞机和巴士,坐火车便宜很多,人们可以省下很多钱。而且,做坐火车也更加安全。人们不用担心坠毁,这地发生在飞机和巴士上。第二,我们可以在火车上欣赏风景。虽然火车很慢,我们可以好好看看美丽的风景,当我们去西藏的时候,可以在旅途中看到不同的颜色和不同的大山。坐火车是最好的旅游方式。
我的缺点之一是写字老是歪七扭八,常常让妈妈说这个字要改,那个字写得不工整,其实我是因为想赶快把手边的功课写完好出去玩,才把功课写得乱七八糟,还自以为是草圣张旭呢,我改过这个缺点的方法是:首先要把书桌清空,不要让会影响我的杂物摆在桌上,开始写功课时必须心平气和的慢慢写,不任心浮气躁找上我,写完功课以后一定要再把功课彻彻底底的检查一遍,才不会出现错误,有了这样的改进,成果似乎慢慢浮现了。
我的缺点之二是每次总是爱跟妈妈顶嘴,只要妈妈讲一件事,我总会连珠炮似的跟妈妈辩驳,我常以我的三吋不烂之舌,把妈妈顶撞的哑口无言,脸上一阵青一阵白,我的成就感油然而生,不过顶撞长辈似乎是件不礼貌的事,可是每每我都会妈妈争得面红耳赤,后来我的解决方法是先冷静慢慢听妈妈把话讲完,再跟妈妈说我的想法,经过几次沟通之后,我们渐渐能了解彼此的想法,也懂得良性沟通。
缺点是全人类如影随形的恶梦,所以我们要尽力把缺点这个噩梦驱逐出境!也愿我们挑战成功!
