After her parents separated, things at tam’s house changed. Her mom, still working, and Tami became responsible for the house and making meals for herself and her younger sister. Though money was right, they never went without. They had a nice home in a modest neighborhood food, belching and shelter. What Tami missed most of all, though, was family.

Tami spent the summer during her ninth grade year working at a park to ear exam spending money. Her job was to organize activities for the kids who spent their summer days at the park. The kids absolutely loved Tami. She was constantly going out of her way to do things for them. She would plan picnics, organize field trips and even buy ice cream for all of them, using her own money. She always did more than the job required, even if it did mean using her own money.

She got to know one little boy who lived in an apartment across the street from the park. His parents both worked at fast – food restaurants, and she knew that they didn’t have much money. The boy talked about his upcoming birthday and the fire truck he wanted so badly. He said he was going to be a fireman some day and needed the truck to practice. He told Tami more details about the truck than she knew a boy truck could have.

The boy’s birthday came and went. The next day when Tami saw the boy, she expected to see a shiny red truck in his arms. When he arrived empty – handed, she asked whether he had got the truck. The boy said no. his parents were going to get it for him later, when things were better. He seemed a little sad.

That week, Tami eased her paycheck and headed for the toy stores. She found the truck easily – after all, from his descriptions, she felt she knew it inside out. She used the money from her paycheck to buy the truck, and then had it wrapped in birthday paper.

Instead of hitting the beach, fourteen high school students traded swimming suits for lab coats last summer and turned their attention to scientific experiments.

   The High School Research Program offers high school students guidance with researchers in Texas A & M’s College of Agriculture and Life Sciences. Jennifer Funkhouser, academic adviser for the Department of Rangeland Ecology and Management, directs this four-week summer program designed to increase understanding of research and its career potential.

   Several considerations go into selecting students, including grades, school involvement and interest in science and agriculture. And many students come from poorer school districts. Funkhouser says, “This is their chance to learn techniques and do experiments they would never have a chance to do in high school.” Warner Ervin of Houston is interested in animal science and learned how to tell male from female mosquitoes. His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school students.

The agricultural research at A&M differs from stereotypes. It’s “molecular(分子)science on the cutting edge,” Funkhouser says. The program broadened students’ knowledge. Victor Garcia of  Rarcia of Rio Grande City hopes to become a biology teacher and says he learned a lot about chemistry from the program.

At the end of the program, the students presented papers on their research. They’re also paid $600 for their work—another way this program differs from others, which often charge a fee.

Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and plowing and that research can open many doors.

Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off—and on again when you return. You will choose the temperature for each room, the lighting and the humidity. A sensor will find the presence of a human (and, with luck, ignore the dog!) and turn the systems on, and when the humans leave it will turn them off again.

The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will find faulty electrical appliances, plugs or switches, separate them so that they cannot harm anyone, and then warn you that they need repair. They will detect(發(fā)現(xiàn)) fire and if you are out of the house, the computer will call the fire brigade. It will not be too difficult because the locks on the outside doors will be electronic. You will open them using your personal card—the one you use for shopping—maybe using a number known only to you.

It will be impossible to lose the key, and a housebreaker will have to tamper(撥弄) with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer.

The computer will be more than a fireman-policeman-servant. It will be an entertainer, and most of your entertainment will come right into your home. It does now, of course, but by 2040 “entertainment” will mean much more. For one thing, you will be able to take part actively, rather than just watching.

B. in 2040 we will use much more lights and heaters

D. in 2040 lights and heaters will be on and off automatically

47.   Which of the following statements is NOT true?

The sensor is multi-functional.

Without a computer, the sensor cannot do much.

The sensor will detect fire and make an emergency call.

You can be taken for a housebreaker if you tamper with the lock or with a window.

48.   According to the author, in 2040, new technology _____.

A. will free us from the keys we use today
