1．We have always been warned of the dangers of the forest fires. They cause     1   to a forest. They kill many plants and animals in an eco-system, which is a group of living things and their environment. But have you ever heard of a forest fire that can be     2    for a forest?
2．People start some of the fires with special reasons to actually do well to the eco-system.
3．In fact, fires are a natural part of any eco-system. Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can       3      some of these old trees. When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.
4．Some trees even need fires to grow. These trees hold their seeds(种子) inside. Heats from a fire allow the coat of the seeds to open up. Then the seeds fall to the ground and have the 4 to grow.
5．Scientists, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or 5   a large space of the forest. Fires can be dangerous for animals. Even when animals continue to live after forest fires, they can go hungry   6    their food has been damaged in the fire. Small, controlled fires mean that animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This   7 makes an eco-system.
6．So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.

People cannot reach an agreement on the use of science and technology. For example, will radiation from electronic equipment destroy the environment? Should medical scientists change gene structures to prevent genetic disease or to create “more perfect” human beings? While people are arguing about these and others, technology continues to influence our everyday lives—the home, health and education, entertainment and communication, and so on.
Some people carry on active social lives with computers —their own or the ones in public places like cafes, social centers, libraries, and so on. Communicating with others in chat rooms, computer users can get to know people they might never meet in traditional ways. With live online video connections, two people with cameras in their computers can see and talk to each other from separate places.
With modern telephone technology, most people stopped writing lettters—especially personal letters and notes. But now, writing to communicate has returned in electronic form, or e-mail, which is a way of sending messages from one computer to another. For some computer users, the wish to communicate intelligently or creatively with others makes them want to write better.
Computer technology has also made it possible to run a house electronically. From turning lights on and off to starting the coffee and cooking the hot meal, computers are taking care of people at home. Many modern machines have computer chips that allow their owners to program them. For instance, you can “instruct” a microwave oven how to cook a dish. Most entertainment equipment operates with computer technology too. Computers can even start cars automatically so that on cold winter mornings you can get into a warmed-up vehicle and drive off.
Although much of the technology in our everyday lives has good effects, there are some uses that raise questions. For example, are interactive media ( i.e., a combination of television, telephone, and computer) going to control minds, cause people to forget about family life and personal relationships? What effects will the genentic engineering of food have on people’s health? High-tech medical treatments can make a person live a much longer life, but can they improve the health and happiness of human beings? Only time will tell, but, in the meantime, science and technology will continue to move forward.
