Since the 1970s, with the worsening oil crisis, the major businesses in the automotive internal combustion engine as much as possible to reduce the car's fuel consumption, while sparing no effort in the development of hybrid vehicles and new energy vehicles. There are hybrid gas-electric hybrid and mixed fuel in two forms, both in the car body design is no different with the traditional internal combustion engine vehicles, the future trend is nothing more than a continuation of current trends, efforts to reduce the drag coefficient, reducing weight while increasing strength and stiffness and so on.
Hybrid vehicle technology only in the product over, to really new energy vehicles, preparatory and experimental products, the ultimate trend or completely replace the existing traditional energy vehicles by the new energy vehicles.
City traffic is a big problem in some cities in the world, especially in big cities. To solve the problem, someone are in favor of developing buses as means of city traffic. Others are in favor of the subway. Between them,which is the better choice?
在世界上的一些城市中城市交通是一个大问题,尤其是大城市。为了解决这个问题,有人赞成发展公交车作为城市交通的方式。另一些人则赞成地铁。在它们之间,哪个是更好的`选择?
It is easier to take buses as means of city traffic than the subway trains because buses don't need special roads. But buses have also many disadvantages, some of which are very serious. They may cause louder noise and more traffic accidents. Buses give rise to serious air pollution and traffic jam. In order to stop what buses cause, a large amount of hand must be used to widen the roads. On the contrary, the subway train is of more advantages. Except the difficulty and high cost of building the subway, it is superior to the buses in many aspects.
公共汽车作为城市交通方式要比地铁容易,因为公共汽车不需要特别的道路。但是公交车也许多缺点,有些是非常严重的。他们可能会导致噪音和更多的交通事故。公共汽车也导致了严重的空气污染和交通堵塞。为了阻止公交车带来的后果,必须用大量的人力来拓宽道路。相反,地铁列车有着更多的优势。除了建设地铁的难度和高成本外,在许多方面它都优于公共汽车。
Taking the advantages and disadvantages together into consideration,I would be in favor of developing the subway train as soon as possible.
把优点和缺点一起考虑,我会赞成尽快发展地铁。
In 2080, cars are going to be different. The car of new type is made from China. The motor is quicker than other cars. The car can be droved 500 kilometers per hour.

By the time you read this you will be 30. At the age of 18 I had so many hopes and dreams about where you'd be, what you'd be doing and with whom you'd spend your life with.
Right now I hope that you have traveled and seen everything you've always wanted to, both in Canada and overseas, and maybe even settled down somewhere in Australia doing some research in the field of biology (genetics.
I hope you're married to the man of your dreams. The man of mine is Gwynn. He is originally from South Africa (another place I wish to visit.
You'll probably have two children of your own – a girl(Michaela Anne and a boy (name yet to be decided.If everything goes according to plan you'll be living in Australia in a big house in a small town outside of a big city with a lot of land, a dog, Gwynn and your two beautiful children. Hopefully you have a career in the medical field, maybe doing research in genetics. Gwynn will be a computer programmer and you will be doing alright for yourselves.
However, if things don't go according to plan for you, I wish you all the love, happiness and joy in the world and don't settle for anything less than the best since that is absolutely what you deserve.
Live long, be happy and live life to it's fullest.

大约在几亿年前,地球出现了第一批生物——恐龙。它们主宰着这世间万物的一切。然而这样的日子没过多久,恐龙便无影无踪的消失了。对于恐龙灭绝事件,科学家这样猜想:小行星撞击地球,大地蒸发,空气下降,天气频繁下雨。正是宇宙粒子流的爆发导致了地球气候的剧烈变化,而不能适应此种气候变化的恐龙,也因此在较短的时间内灭绝。
恐龙虽在这短暂的时间内灭绝了,但还有一群生物躲过了这次的灾难,生存下来了。就是现在的`我们——人类。但由于人类的不珍惜、不爱护、破坏大自然、乱砍乱伐。为了满足自己对食物、淡水、木材、燃料的需要,在过去的60年中,被人类开垦为农田的土地比18世纪和19世纪的总和还要多。
又一次的灾难降临到了地球,人类灭绝了。蚂蚁有活了下来,它们同人类一样破坏地球,最终的结果只能是死无葬身之地。灾难果真降临了。这次的灾难比恐龙消失更要可怕。地球的破坏者,也就是蚂蚁们,它们的尸体全都悄无声息的消失了。也许是上天在惩罚它们这群肆意妄为的地球破坏者吧!
恐龙、人类、蚂蚁他们明明掌管了地球,得到了幸福,为什么却有全都灭绝了呢?答案只有一个——就是因为他们不懂得珍惜环境。
同学们,我们要珍惜我们共有的家园!保护坏境,与大自然和谐相处!让恐龙灭绝的悲剧不再重演!
呼!呼!屋外刮起了强烈的暴风。
哗!哗!窗外下起了狂烈的暴雨。
这时的我正倦缩在家中,突然天空中电闪雷鸣,在屋外形成一股龙卷风。我十分好奇,跑出去偷看这巨大的龙卷风,但这时不知有一股什么力量就把我卷入龙卷风中,我哭了,我开始大喊,但因为龙卷风太强大,没人敢出来,我开始悔恨……
不知多久过去,我隐约中听到鸟叫声,我慢慢睁开眼睛,眼前的一景犬如梦幻般神奇,我开始想:“我是否已经来到天堂,不对,天堂怎么有小鸟……这时我想到一个办法那就是捏我自己一下。”我就如捏了自己脸部一下,呀!挺痛,看来不是梦。于是我就开始狂跑。
在这幻境——这里到处都是花草树木,给人一股厅幻般的感觉,这里的动物是如此的多,有大象,老虎……还有古代一些灭绝动植物,它们是如此的温柔,对我十分友好,我就与它们在草地中嘻戏,这里的空气是如此新鲜,呼吸时使人心旷神怡,神清气爽。
嘻戏一会儿后,所有的动物都向一个方向走去,走的如此的轻,生怕把他们地上的朋友——草本植物给踩痛了!飞的如此的高,生怕碰着长得高大的朋友——具有形成层的`木本植物。
于是,我也跟着跑了过去,眼前的一幕把我惊啦!
那是生活着一群人,男耕衣种,无忧无虑,生活如此安祥。
中午到啦,该吃午饭了,只见每类动物,植物都会大公无私的把自己奉献给需要他们的人,动物有时把自己奉献给人类食用,植物也会把自己奉献给动物,食草动物也会把自己奉献该食为动物,空气与阳光会把自己奉献给植物……,于是我毫不犹豫的加入他们……
这里只有光明,没有黑暗,这时我才明白,这就是真正的生活,生命的真谛,真正的生活环境,真正的地球。
