Modern technology has developed in a manner which often conflicts with the environment．Nevertheless, it is possible and practical to achieve a high level of technology without altering the overall natural environment.
There are two basic methods of conserving(保护) the natural environment．One is alternative technology in which techniques (such as windmills and solar energy) must be found for providing power．The other is to try to minimize the effects of modern technology by the more efficient use of materials and more effective pollution control．There comes a point when the quality of life can no longer be improved because of the high population density(密度) and the largely unsuccessful at tempts to meet its demands.
Present energy policies of the western world are considering new energy sources to meet the demands of a growing population．The main sources used have been oil, gas, and coal- which are in limited supply- and nuclear power, which has problems concerning radioactive waste storage．Wind and solar energy are alternative possibilities, but only solar energy is likely to become a main power source for many countries.
Many of the materials used daily in a technological society are destined(注定) to be discarded, Rags, paper, metal, glass, and plastics are all substances that could be recycled or reused．Research is being done to determine methods of separating useful products from industrial and domestic waste.
The processing of sewage requires considerable amounts of electricity．Many sewage treatment plants in the U.S．have become self-sufficient by using the methane gas(沼气) given off by sewage．This is collected in gas holders and burned to produce heat and create electricity．The solid waste itself is often used for soil enrichment.
1．Modern technology is harmful to the natural environment because ________
A．of industrial pollutants.
B．it has become too expensive.
C．it has become too complicated.
D．it consumes all natural resources.
2．Alternative technology suggests that ________
A．new ways be found to burn coal, oil and gas.
B．solar energy and wind power be considered.
C．new ways be found to store radioactive waste.
D．the present energy resources be fully used.
3．Methane gas in used to ________
A．conserve(保存) industrial residues (废料).
B．create recycled paper products.
C．provide electricity to process sewage.
D．treat with the raw sewage.
4．From the selection, we can determine that ________
A．conservation technology is a necessity.
B．nuclear power is the energy source of the future.
C．problems of energy conservation are not worldwide.
D．all the industrial and domestic wastes can be reused and recycled.
5．Processing sewage requires large quantities of ________
A．water.
B．electricity.
C．gas.
D．oil.

roblems. Some pollutants can cause breathing disorders, diseases of blood and even cancer. Most scientists 43 that every modern house has some kind of indoor pollution. People began to 44 the problem in the early 1970s, when it was that builders began making houses and offices which did not waste energy. To do this they built buildings that 45 the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to 46 harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control 47 for building green plants. Scientist do not really know how plants control air pollution. They believe t
hat a plant’s leaves take in the pollutants. In exchange the plant produces oxygen 48 its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each 49 different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.To be able to motivate oneself, or self-motivate, occurs when a person has the willingness to do something and is internally(内在地) motivated to do it．
Sometimes it’s very difficult to get ourselves moving．The natural tendency is to postpone．Life just seems to get in the way! There is a job to go to, groceries to do, television to watch—whoops! I guess we get pretty good at finding excuses to escape getting started on goals like an exercise routine or reading a new book．The fact is that we are creatures of routine and habit．So what can we do to motivate ourselves to accomplish our goals?
Here are some tips on how to get moving:
Decide what you want．It’s hard to motivate an aimless mind．Set a goal and decide how you are going to go about it．Then break it down into smaller sections so it’s easier to handle and less overwhelming．（势不可挡）
Keep track of your progress．Keep a log or journal where you can measure how much you have accomplished．Looking at it can also motivate you to keep pushing ahead．
Post motivating pictures or slogans within your sight．It is always inspiring to see pictures of people who have accomplished what you’re going for．It makes it attainable and realistic．Likewise, little slogans like “go for it” or “just do it” can give you the little support you need．
Sometimes we forget what we set out to do and a little reminder is all we need to be revitalized (激活) and focus on the end result．If you remind yourself to go for the desired promotion, it will re-establish why you are doing what you’re doing．
Make it a habit．Once you have accomplished your objective, e．g．becoming an early riser, keep it up so that it’s second nature to you and you don’t have to think about it anymore．
