     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 (数字的) 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 (燃料). Coal,

natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy (能源).

     Schools will go electronic (电子化). 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.

Questions 81-90 are based on the following passage.

It sounds like a science fiction, but researchers say it’s a scientific fact: Microscopic organisms dubbed "killer algae" are paralyzing fish with unknown toxins and then eating away at their flesh. They might be making people sick, too.
The name given to this single-cell organism, or dinoflagellate, is Pfiesteria piscimorte- literally, "fish killer. " It was discovered at North Carolina State University in 1988, but at the same time, few scientists believed in its existence, much less in its highly unusual predatory nature. But ongoing research has led to international acknowledgment of the phenomenon and, recently, research funding.
Seemingly prompted by an unknown substance secreted by fish, the aggressive creature swims into action. It sends neurotoxins into the water and air, paralyzing a fish’s nervous system, and causing it to gasp for air at the surface. Eventually the fish suffocates. The killer dinoflagellate then attaches itself to the fish and begins sucking away at its flesh. This macabre scenario may help solve several sea mysteries, such as why fishermen report seeing "fish walks" (fish trying to leave the water) and pools of dead fish with holes eaten through them.
Whether humans are affected by the dinoflagellate’s toxin remains to be seen. Researchers think it’s unlikely eating fresh fish are in danger, but anyone with frequent exposure to the creature could be in peril. Several researchers working with the algae have reported bouts of memory loss and disorientation.
To understand the killer algae further, scientists must fully characterize their toxin and determine what stimulates them to attack. They also need to know if the algae are hurting fish populations, and whether pollutants make them more likely to attack.

The passage is primarily concerned with ______.

A. informing readers of different sea creatures
B. describing predatory microscopic organisms
C. solving some long-lasting mysteries about the sea
D. discussing the environment for various fishes
