What will our life be like in 50 years？No one knows the answer exactly，（1）but we are sure that it will be very different from the life today.My brother Bob White makes some predictions.Here are some of his ideas.
   First，people will have less work to do，and robots will do most work.People will use robots to make cars，do the housework，look after sick people and teach students.People will spend most of their time playing sports and traveling.So people will become stronger and healthier，（2）并且人們將會(huì)活到200歲。
   Second，cars will become very small and computers will control their speed.So there will be fewer accidents on the road.Planes will be very popular，and most people would like to take them to travel.
   Third，people will be able to live in the sea，on the moon or on Mars.The earth won't be crowded or noisy.So there will be much space for people to plant trees.（3）污染將會(huì)更少，水會(huì)更新清。
   Finally，water shortage will become one of the most serious problems.（4）If people don't save water now，there will be water wars in 50 years.
