B. 谈论2050年的虚拟世界生活的英语作文
现在的世界很美好，但是也有美中不足的地方。比如：现在的汽车有尾气，会污染环境；现在有很多高楼大厦，依然有很多高楼没安装电梯；现在的房子很容易遇上地震，一旦遇上地震就会倒塌，……。还有许多贫困的人……。。到了2050年，这些烦恼将会得到解决。。这时的汽车升级到FIG版（就是高级版），它的身型和现在的汽车没什么两样，只是尾筒里不会喷出二氧化碳，只会喷出香味；它的轮胎是由改性橡胶做成的，10年才换一次。车壳比现在使用的钢还要坚硬，即使发生交通事故也不会变形。车顶装有小型太阳能电池板，用以代替汽油，它小而吸收大的能量，只要吸收一天的阳光，就可以使用一年，这样的汽车真节省能源啊！现在的高楼大厦有一部分没安装电梯，让人们爬上爬下，很不方便。但到了2050年，家家户户都有了电梯，而且这些电梯都安装了“快速引擎装置”，只要你说去几楼，它会在6秒之内到达你要到的地点。假如发生了地震，这些房子会提醒你地震，然后启动“超高速喷气”，这时，白白的无害烟从房底喷出，房子就会凌空飞起，自动降落在安全的地带。到了2050年，全世界都是富人，再也没有贫穷、饥饿；再也没有乞丐，没有人去流浪。这时，家家有了小轿车，私人小飞机、快艇，人们生活提高了许多。但人们不会因有钱而不劳而获，而懒惰。未来的2050年虽然离现在还很长很长，便为了这美好的一年，让我们共同努力奋斗吧。
C. 一篇写未来科学技术发展的英语作文，不要太长，不要太短，大学六级难度
21st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet, computer, and cellphone. These new technologies make our life much easier and better.
First, the development of computer changes our life. Decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. As the result of that, people spent hours on the equations that a computer can solve in just a minute. Since the development of computer, people are able to use some kind of software to compute lots of complex functions and mathematical calculation. Computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently.
Also, internet is another useful tool for us today. The development of internet brings a great impact toward the society. Instead of going to library and fliping all the books to figure out some information, we can just simply use a mouse and click on the website to do research. The internet leads us to a place where we can find unlimited information and resources. It makes our life much easier and better.
The last technology is cellphone. Nowadays, many people have a cellphone. But it just appears on the market for about 10 years. It is very convenience to the users because we can talk to anyone we want with a phone as small as a wallet. Also, we can communicate with others by making a phone call instead of sending letters. It is very fast and useful way to communicate.
In conclusion, I believe the development of technology brings significant impact to our life. It is very helpful to us and I believe technology will keep improving in future.
I HOPE IT HELPS!

G. 以虚拟世界为题写一篇英语作文
The two great inventions, computer and Internet, have been developing at a surprising speed in the past half century. At present, a virtual world has been built roughly, which is quite different from the former real one.
In virtual world, by the aid of advanced communicating means, people contact each other wider, more convenient and much cheaper than those in real life. Never could I, a Chinese, imagine that I’m able to talk with my American friend free across the Pacific in traditional society. It seems that the virtual world is smaller than the real one.
What’s more, it’s shown on screen and heard from earpiece rather than being touchable that everything in virtual dimension is possible not to be real, as a famous saying among cyber worms, “Nobody knows you are a dog.” Speech freedom is enough, though, netizens suppose it necessary to keep private matters secret.
What is done can’t be undone in real life, in addition, and yet you can find it possible to revive yourself in computer games and to restore deleted documents in virtual office. What we have done can be rescued in virtual world.
Nowadays, the two dimensions are combined closer and closer. In my opinion, keeping a balance and living a colorful life seems to be our goal.

Virtual Reality
Virtual reality (VR) is a technology that allows you to enter and interact with a world that is generated by a computer. Special graphics, video images and stereo sound make this pretend world seem real.
The uses for virtual reality are wide ranging and cover everything from games where you can drive a car, fly a plane, ski down a mountain or track a dinosaur - to helping train doctors in the art of surgery or teaching pilots to fly aircraft safety. These computer generated worlds can be any size - as vast as the universe or as microscopically small as atoms and molecules.
Uses Of Virtual Reality
The uses for virtual reality are infinite. It can be used for air traffic control, medicine, entertainment, office work and instrial design. However, along with the good comes the bad. Virtual reality could also be used for destructive purposes, such as war and crime.
The idea of virtual reality emerged in the 1930s when scientists created the first fight simulator for the training of pilots. They wanted to put the pilote in a real situation before letting him fly.
In 1965, an American, called Ivan Sutherland, hit on a new idea and published his findings in a document called 'The Ultimate Display'. His idea was to create a portable, or personal, virtual world using two tiny television sets, one for each eye. In order to realise this, he also designed a head mounted display. Although his invention worked, and he did create a sort of a virtual world, the images were very crude and basic. Another problem was the helmet - it was extremely heavy and cumbersome and needed to be supported from the ceiling. It was also very expensive. In the following years, scientists continued to work on Sutherland's initial idea and great improvements were made. Then in 1985, Michael McGreevey of NASA/AMES developed a much cheaper and lighter version of the helmet. He used a motorcycle helmet and fitted it with mini display screens, and special sensors which were designed to track movement and were linked to powerful, but sensitive computers.
The final piece of equipment for a complete virtual reality kit was a glove. One had been designed in the early 1980s, but modern virtual reality was born in 1986 when a computer games programmer, called Jaron Lanier, designed a new glove. This brought the VR helmet and glove kit into existence for the first time. It was Lanier who gave this new technology the name Virtual Reality.
Types of Virtual Realities
There are three main forms of virtual reality:
The first is perhaps the most familiar. It consists of a helmet which has small TV screens and earphones fitted into it, and a glove (some systems use a joystick or wand instead of a glove). The helmet and glove are linked to computers which are programmed with special sounds and graphics.
The second form of virtual reality uses video cameras to track the image of the user in a virtual world where you can also pick up or move objects. Both these VR systems allow more than one person to take part at the same time.
The final type of VR is where three- dimensional images are played on a large, curved screen. The shape of the screen helps to give you a greater sense of being in the virtual world. By wearing special 3-D glasses, this effect can be greatly improved.
Advantages Of Virtual Reality
VR has a lot of positive benefits. It gives disabled people the opportunity to join in activities not usually available to them. In virtual worlds, people in wheelchairs, for example, can have a freedom of movement that they do not have in the real world. At the moment very few people can afford to buy a VR system. But as the technology advances, lightweight helmets and more powerful computers will take VR into ordinary homes.
Virtual reality has very important uses in all types of architecture and instrial design. Computer Aided Design, or CAD, has been an important design tool since the mid 1970s, because it allows the user to draw three- dimensional images on a computer screen. However, unless you have a VR helmet and glove to project the images on to, you will not be immersed in your virtual world.
Building aircraft
Virtual reality has been a huge boost in the aviation business as it avoids the need to build several different prototypes (models built to the correct size). Every time an engineer designs a new aircraft or helicopter, a prototype has to be built to ensure that it works, whether it will fly fast enough and whether it is safe for the crew and the passengers. If the prototype is wrong, the designers have to go back to the drawing board, make the changes and then build another one. This is a very expensive and time-consuming business.
By using VR, designers can design, build and test their aircraft in a virtual environment without having to build a real aircraft. It also allows the designers to try out different ideas - all the ideas can be looked at in detail and they can then select the best one. NASA has used virtual reality to design a helicopter and Boeing have used it to design their latest aircraft.
Using virtual reality, doctors have already been 'inside' a body. At the University of North Carolina, USA, virtual reality allowed doctors to enter a cancer patient's thorax (part of the chest) to make sure that radiation beams needed to treat the cancer were in the right place. Doctors will soon be able to look at and study tumours at first hand and in 3-D rather than from scans and x-rays.
A virtual body
In the USA, a murderer who was executed on the electric chair donated his body to science. His corpse was sliced into very thin sections from top to bottom and used to create an entire virtual body for medical research. Soon all medical students will be able to train using virtual bodies instead of real patients.
On a microscopic level, virtual reality is being used in drug research. Scientists at the University of North Carolina are able to create the molecules and then visualize and 'feel' how they react with each other. Before the use of virtual reality, this process was very slow and complicated. Therefore, it is likely that virtual reality will have a strong impact on the speed with which new drugs and remedies are developed and become available in the future.
Virtual reality is also important because it can visualize the unknown or the unpredictable. This might lead to virtual reality operators carrying out repairs in space, with the help of a robot. In a technique called virtual puppetry a robot is controlled by a skilled operator and mimics all the operator's movements.
The possibilities for virtual reality are enormous. Future residents of new towns will be able to walk around virtual streets, shops, houses and parks before a single brick has beer laid. There are already plans to redesign the whole of the city of Berlin, the capital of Germany, using virtual reality.
Disavantages of virtual reality
Limited field of view with same lenses, except newest pro models.
requires matching of film type to lighting ad use of color correction (cc) filters.Narrow latitude for transparency film (5 stops). Consumer level (less expensive) cameras have narrower latitudes similar to transparency films.Requires scanning for post proction.Consumer cameras often require long delays (10-30 seconds) between shots while previous image(s) are being saved.Limited resolution compared to film, except for high end (expensive) digital cameras. Consumer cameras are generally limited to full page or less reproction.Scanning slows down post proction speed & adds cost.Digital systems can lose value quickly (up to 50% or more each year). Requires 8-12 photos (or more) for each panorama, more for multi-row (cubic) panos. Cubic viewing requires that viewers have a recent version of QuickTime installed, although this is already standard on most computers.Same disadvantages as film, but digital capture generally requires more source images per panorama in order to yield same field of view as with film.Requires annual license fee for software use. Need special fisheye lenses to shoot, limited maximum resolution compared to QTVR, users must have IPIX™ plug-in or IPIX viewer installed (free), authoring software available only from IPIX.Same disadvantages as film, but with lower maximum resolution (except for extremely high end/expensive digital systems).Expensive, difficult to use when supplemental lighting is required, film-based models not usually capable of fisheye or 360°° coverage.Same disadvantages as film, although digital models are significantly more expensive than film models. Current digital models also require that a portable or laptop computer be tethered to the camera when in use.Low resolution, requires proprietary software for dewarping, hard to visualize resulting image when looking through viewfinder, not capable of 360°x360° views, limited exposure control while shooting. Some also require royalty payment or "processing service" fee for every image created.Same disadvantages as film, but maximum resolution even further limited.
