1 even the automobile industry, which has remained largely unchanged for the last seventy years, is about to feel the effects of the computer revolution.

即便是过去70年间基本上没有多少变化的汽车工业，也将感受到计算机革命的影响。

2 the automobile industry ranks as among the most lucrative and powerful industries of the twentieth century. there are presently 500 million cars on earth, or one car for every ten people. sales of the automobile industry stand at about a trillion dollars, making it the world's biggest manufacturing industry.

汽车工业是20世纪最赚钱、最有影响力的产业之一。目前世界上有5亿辆车，或者说每10人就有1辆车。汽车工业的销售额达一万亿美元左右，从而成为世界上最大的制造业。

3 the car, and the roads it travels on, will be revolutionized in the twenty-first century. the key to tomorrow's "smart cars" will be sensors. "we'll see vehicles and roads that see and hear and feel and smell and talk and act," predicts bill spreitzer, technical director of general motors corporation's its program, which is designing the smart car and road of the future.

汽车及其行驶的道路，将在21世纪发生重大变革。未来“智能汽车”的关键在于传感器。“我们会见到能看、能听、有知觉、具嗅觉、会说话并能采取行动的车辆与道路，”正在设计未来智能汽车和智能道路的通用汽车公司its项目的技术主任比尔?斯普雷扎预言道。

4 approximately 40,000 people are killed each year in the united states in traffic accidents. the number of people that are killed or badly injured in car accidents is so vast that we don't even bother to mention them in the newspapers anymore. fully half of these fatalities come from drunk drivers, and many others from carelessness. a smart car could eliminate most of these car accidents. it can sense if a driver is drunk via electronic sensors that can pick up alcohol vapor in the air, and refuse to start up the engine. the car could also alert the police and provide its precise location if it is stolen.

美国每年有大约4万人死于交通事故。在汽车事故中死亡或严重受伤的人数太多，我们已经不屑在报纸上提及。这些死亡的人中至少有半数是酒后开车者造成的，另有许多死亡事故是驾驶员不小心所导致。智能汽车能消除绝大多数这类汽车事故。它能通过会感测空气中的酒精雾气的电子传感器检测开车者是否喝醉酒，并拒绝启动引擎。这种车还能在遇窃后通报警方，告知车辆的确切地点。

5 smart cars have already been built which can monitor one's driving and the driving conditions nearby. small radars hidden in the bumpers can scan for nearby cars. should you make a serious driving mistake (e.g., change lanes when there is a car in your "blind spot") the computer would sound an immediate warning.

能监控行车过程以及周围行车状况的智能汽车已经建造出来。藏在保险杠里的微型雷达能对周围的汽车作扫描。

如果你发生重大行车失误（如变道时有车辆你“盲点”内），计算机立即会发出警报。

谁没有接触过网络游戏?答案是没有!现在，不论男女老少，都是或多或少接触过已经悄然步入我们生活的游戏。

游戏在本质上，意义都是好的。开发商们都希望制造一个轻松，休闲的游戏环境供大家放松。大部分人玩游戏的初衷同样如此。压力日益增大的我们，渴求在虚拟世界中获得一丝安慰以缓解自己紧绷的生活。不可谓不说，有的网络游戏真的做到了这一点。这便是好处所在，玩过游戏的人也都是领略到了。

再一点，游戏往往成为我们平时谈论的话题，以不至于无话可说而导致关系恶化。而且，在游戏中我们还可以与朋友们遨游天下，争霸一方，这也算是增进友谊了吧。

不过，万物有好有坏。网游固然有他的好处，但是不得不承认，它也有坏处。一部分人，在生活中没有自信，可却在虚拟中能够体会那种在现实无法体会到的自豪，于是——偷钱，抢劫，等等。有些人呢，原来学习很好，可自从染上了网瘾，便一发不可收拾，学习成绩一落千丈，毁了自己的大好前途。甚至有些人，为了游戏，放弃现实生活，沉迷于虚拟的游戏世界，无可自拔。虽说只是个别人，但网络游戏的坏处，却一览无遗。

还有，网游中常常存在一些不良场景，让某些自控能力不强的人深深陷入其中，并一味模仿。他们的心中，受到了不良游戏这双魔眼带来的剧毒!

一个人说，也是起不到什么作用。如果大家一起营造公平，绿色的网络世界，拒绝不良信息的危害，追求轻松娱乐，我想，便是没有人会拒绝网络游戏带来的好处吧。坏处，自然也是成不了什么威风。

不管遇到怎样的困难，都阻挡不了我们学习的脚步，网络这么发达，即使不能在课堂，我们也能接受到，现在我来说说网课的利弊吧……

有利的方面大家都应该知道，就是便捷，打破了传统的教学方式，更加新颖，增加学生的学习兴趣，因为这次疫情，网课无疑是这次教学最好的办法，这种网课的方式，可以避免学生课程拖后现象。而且网络上知识如海，有句话怎么说来着，叫海纳百川，你想学习的，网上几乎是找得到的。

网络学习了也打破了传统模式的时间和空间条件的限制，是传统学校功能的'延伸，网络学习为人们提供了在任何时间、地点、环境下进行学习的选择，使有限的资源辐射到更多的人员和地区。网络学习方便便捷，但是一定要劳逸结合。

其次就是网络学习的弊处，首先大家知道，网络学习要一定的设备，网课是信息化时代的产物，软硬件兼备才能保证网课的顺利进行，但对于一些贫困地区和家庭，以及网络不好的学生来说，这无疑是雪上加霜。而且一部分教师对网课也不太熟悉，网课软件的运用，对一部分年长的老师，也是一种考验。

最大的问题就是容易陷入形式主义，网课的目的是让学生听进去，还要学到知识，尽可能保持学习效果。但是学生每天签到打卡，不一定有好好学习，不能像在教室里一样，随时能监督到他们。网上教学效果是真的难以保障，授课老师很难直观了解到学生对知识的把握程度，也限制了学生想象力和创造力的发挥。任何一个事物都是有两面性的，网课也是如此，在网课的学习中，一定要注意保护好眼睛，学习完之后，多望望远方，减轻眼睛疲劳。

祸兮，福之所倚；福兮，祸之所伏。挑战与机遇并存，自律的人一定能在这次网课中受益匪浅；倦怠的人，则会被狠狠落下。

in the picture, we can see that some young ladies are dressed in fashionable clothes. they are joyfully showing some latest sorts of the garment . with the steady growth in the country’s economy as well as the people’s living standard, fashion has become big buisness and has influenced a lot of people’s daily life. however, traditionally, some people take negative attitudes towards the pursuit of fashion. whether one should follow the fashion trend is a constant topic of debate.

in my opinion, the love of beauty is a nature of human beings. everyone wants to be beautifully dressed so that he or she can display the best self in front of others. fashion changes are the inevitable result of the advance of human civilization and are also a mirror of social progress. fashion now has already become a flourishing industry, which contributes a lot to the economy and the society. besides, fashion gives expression to new ideas and originality and offers an unlimited scope for talented artists.

however, it cannot be denied that there are some disadvantages to the pursuit of fashion. if everyone is overindulged in the pursuit of fashion, individuality and uniqueness will get lost to the public. also, it is a costly hobby to follow the fashion, leading to extravagance of time，energy and money. what's worse, to follow the fashion blindly will make one get addicted to faddism, which will probably lead to superficiality of one’s intellect and thinking. therefore, we should take a serious attitude towards the poursuit fashion.
