Virtual Heaven

If you could live forever, would you want to? The challenge o keeping your body alive seems impossible, but some scientists are working on an alternative. They want to create a digital copy of your "self" and keep that copy " alive" long after your physical body has stopped functioning. 

In effect(实际上), their plan is to clone a person electronically(电子装置). Unlike ordinary physical clones- which have identical features as their parents, but which are independent organisms, each with a different conscious self- your electronic clones would believe itself to be you. How might this be possible?

One plan relies on the development of nanotechnology(纳米技术).Ray Kurzweil, a leading futurist, predicts that within two or three decades we will have tiny transmitters that can be injected into the brain. Once there  they would line up alongside neurons（神经元） and monitor the details of the brain's activity. They would then be able to transmit that information to receivers inside a special helmet, allowing us to map the brain.

As a further step, Kurzweil foresees using these tiny transmitters to connect you to a world of virtual reality. With the transmitters in place, you could think your way onto the Internet. Instead of seeing pictures on a screen, you would see them in your mind. Rather than send emails to your friends, you could meet them on some virtual tropical beach and exchange messages in " virtual person". For a futurist like Ray, this would be heaven, a virtual heaven. Once you upload the brain onto the Internet and log on to that virtual world, your body can be left to decompose(腐烂 分解) while your virtual self can play games for as long as you wish. However, these is  still a problem. To exist on the net, your virtual self will have to reside on the computer of a web-hosting company. These companies want to be paid real money, or they will delete your "self" and sell the space to someone else. With your body long gone how will you pay?

1. According to the article, extending life digitally maybe possible, but... ?

----it will be not be practical.

2. What would happen if you couldn't pay to exist on some's computer?

-----You will be deleted.

3. Neurons are....----nerve cells.

4. A futurist is someone who....----studies trends and makes predictions.

5. How was an electronic clone different from a physical clone?

----Unlike ordinary physical clones- which have identical features as their parents, but which are independent organisms, each with a different conscious self- your electronic clones would believe itself to be you.

6. What can happen to your body after you brain has been uploaded onto the internet?

----Once you upload the brain onto the Internet and log on to that virtual world, your body can be left to decompose(腐烂 分解) while your virtual self can play games for as long as you wish.

9. Once you upload your brain onto the internet, you can leave your body behind.
