阅读理解。 What will life in the future be like?Will it be much better than it is now? And what will we be able to do 10,20 or 30 years later? Let's just close our eyes and think ! Genetic Engineering Cenetic engineering will help us create the perfect human.  Babies will grow up to do slam dunks like Yao Ming or look like Cecilia Cheung. Also,we will be able to mix( 杂交)  plants and animals !  But do you want your dog to be a tree? The Dead In the future,we will be able to bring the dead back to life.  Then each family can meet and talk with its dead family members. It will be like living with ghosts. On television people will see Albert Einstein, Marilyn Monroe, Confucius, Elvis Presley, and Shakespeare talking with each other! Long-Iiving People Over the next 20 t0 50 years,it will become harder to tell the difference between human and machine. All body parts will be replaceable.We will then be able to make fake (假的) people. We will make a copy of ourselves,so we will appear to be alive long after we are dead.  A few decades later,people will find ways to transfer (转移)  their spirit (精神 )  to the new body. Nanobots We will be able to build nanobots (纳米机器人) to travel through our body. Also,nanobots will be used when we are sick. For example,when we have a stomachache,we will swallow a very small robot and it will travel through our stomach,taking video of what's happening there.  Then we can show the video to help the doctor diagnose (诊断)  our problem. Computers Computers help us remember,calculate,and enjoy ourselves. In the future,computers will be able to show their feelings. They will be able to think better than the human mind. After television became popular,many people soon became couch potatoes . It is not surprising that many people have become overweight; and things will get worse in the future ! We will be more and more interested in computers and the Internet,spending more and more time in front of computers and forget what our real needs are.  Many of us will become super couch potatoes and weight 250kg! 1.
