What might the future be like? Here are some predictions: things to come, things to go.    The Spring Festival, the most important Chinese holiday when everyone returns home, has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020. And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.    Newspaper will come to an end in 2043. In the future, digital newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster.   Oil is running out faster than expected. But scientists have found something else for oil as fuel. Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy.   Schools will go electronic. Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students' library, schoolbag and connection to the outside world. There will be robot teachers. They will check homework on computers and communicate with the students' parents through e-mail. And school buses will be like spaceships, comfortable and safe. More than 2 billion people have a hard time returning home during  _  .
