Will life in the future be better, worse or the same as now? Futurologists（未来学家）predict that life will probably be very different in 2050.

First of all, it seems that TV channels will have disappeared by 2050. A computer will send the program directly to the television. On TV screen appear holograms（全息图）, which are pictures with certain height, width and depth. We will be able to see, smell and touch the things that we see on television.

Water has become one of our most serious problems. Agriculture is changing and people are growing more fruit and vegetables to export. Demand for water will increase ten times in 2050. Some futurologists predict that water will be the cause of war if we don’t act now.

In transport, cars will run on new fuels and go very fast. A car will have computers to control its speed and there won’t be any accidents. On the other hand, space planes will take people around the earth in about three hours. People will fly from Los Angeles to Tokyo by space plane in just half an hour.

In the field of technology, robots will have replaced people in factories. By 2050, we will see robots everywhere. They do not ask for pay rises or go on strike, and they work 24 hours a day.

Medicine technology will have conquered many diseases by 2050; we will be able to help blind and deaf people see again and hear again. Scientists have discovered how to control genes. They have already produced clones of animals and will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. If you want all this to come true, you should study science and technology hard.

The most frightening words in the English language are, “Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, “I’m sorry, I can’t sell you a ticket. Our computer is down.”

“If your computer is down, just write me out a ticket.”

“I can’t write you out a ticket. The computer is the only one allowed to do so.”

I looked down on the computer and every passenger was just standing there drinking coffee and staring at the black screen. Then I asked her, “What do all you people do?”

“We give the computer the information about your trip, and then it tells us whether you can fly with us or not.”

“So when it goes down, you go down with it.”

“That’s good, sir.”

“How long will the computer be down?” I wanted to know.

“I have no idea. Sometimes it’s down for 10 minutes, sometimes for two hours. There’s no way we can find out without asking the computer, and since it’s down it won’t answer us.”

After the girl told me they had no backup(备用) computer, I said. “Let’s forget the computer. What about your planes? They’re still flying, aren’t they?”

“I couldn’t tell without asking the computer.”

“Maybe I could just go to the gate and ask the pilot if he’s flying to Washington, ” I suggested.

“I wouldn’t know what gate to send you to. Even if the pilot was going to Washington, he couldn’t take you if you didn’t have a ticket.”

“Is there any other airline flying to Washington within the next few hours?”

“I wouldn’t know, ” she said, pointing at the dark screen. “Only ‘IT’ knows. ‘It’ can’t tell me.”

By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage.

While scientists are worried that humans are causing higher temperatures on the Earth, a Maryland man, Ace, thinks we can save the world by spraying（喷射）huge amounts of water into the air.

Ace told the McClatchy News Service that at least 1,000 places should be chosen to spray water. The water would be sprayed between 20 and 200 feet into the air. Thousands of tons of seawater would be sprayed for years at a time.

The 1,000 sites would be picked after more studies. They would be mostly in the Northern Hemisphere(北半球). Ace says he would avoid tropical（热带的）areas of the globe. He says water turns to rain too quickly in these areas for his plan to work.

The water would be changed into vapor. That process requires heat. The water vapor would rise above the Earth. The water vapor would form clouds. The clouds would help in several ways. They would cool the Earth by reflecting sunlight. They would later turn into rains. The rains would provide another way of cooling the Earth.

Ace’s plan has gotten some support from a limited scientific study. Kenneth Caldeira is a climate scientist. He works at the Carnegie Institution’s Department of Global Ecology at Stanford University in California. Caldeira tested some of the Ace’s figures on a computer program. The computer model is used by top scientists to study global climate change. The model showed that the plan might work.

“More tests are planned in 2009. Ideas like Ace’s should be considered carefully and with an open mind,” Calderira said. “Every brilliant（卓越的）invention in the history of technology looked a little bit mad when first put forward.”

65．What’s the purpose of Ace’s plan?

A. To reduce air pollution.

B. To make summer cooler.

C. To offer dry areas more rain.

D. To solve the problem of global warming.

66．According to Ace’s plan,___________.

A. planes would be used to spray water.

B. it would be best to spray water on rainy days.

C. seawater would be sprayed high into the sky

D.1,000 sites in the Southern Hemisphere would be chosen.

67．Why wouldn’t Ace spray water in tropical areas?

A. Water is changed into vapor too quickly.

B. Water turns to rain too quickly.

C. It is hard for vapor to form clouds.

D. It is bad for local plants to have too much rain.

68. It seems that Caldeira ____________.

A. takes Ace’s plan seriously

B. thinks Ace’s idea too crazy

C. doesn’t believe the computer’s result

D. agrees to carry out Ace’s plan right away
