But eventually, kids grow up and become teens．It’s totally normal for teens to create their own opinions, thoughts, and values about life; it’s what prepares them for adulthood．But as you change and grow into this new person who makes his or her own decisions, your parents may have a difficult time adjusting themselves to it．
In most families, it’s this adjustment that can cause a lot of fighting between teens and parents．Teens get angry because they feel parents don’t respect them and aren’t giving them space to do what they like, and parents get angry because they aren’t used to not being in control or they disagree with the teens’ decisions．
It’s easy for feelings to get very hurt when there are conflicts like these．And more complicated issues can cause even bigger arguments, because your parents will always be intent on protecting you and keeping you safe, no matter how old you are．
The good news about fighting with your parents is that in many families the arguing will lessen as parents get more comfortable with the idea that their teens have a right to certain opinions．It can take several years for parents and teens to adjust to their new roles, though．In the meantime, concentrate on communicating with your parents as best you can．
Sometimes this can feel impossible — like they just don’t see your point of view and never will．But talking and expressing your opinions can help you gain more respect from your parents, and you may be able to reach a compromise that makes everyone happy．Keep in mind, too, that your parents were teens once and that in most cases, they can relate to what you’re going through．

“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland．“There is certainly a lot of energy in waves．”
Scientists are working on using that energy to make electricity．
Most waves are created when winds blow across the ocean．“The winds start out by making little ripples （波纹） in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ”Taylor said．“Waves are one of nature’s ways of picking up energy and then
sending it off on a journey．”When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a l
arge wheel called a turbine （涡轮） ．The turbine can then power an electrical generator （发电机） ．The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland．
The resource is huge．We will never run out of wav
e power, besides, wave energy does not create 
the same pollution as other energy sources, such as oil and coal．Oceans cover three quarters of the earth’s surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．
Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus, wave power would get in the way of fishing and boat traffic．
With more research, however, “many of these problems might be overcome,” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．”
In the future, when you turn on a light switch, an ocean wave could be providing the electricity!
小题1:Which of the following is NOT true?
| A．Wave power doesn’t cost too much money． |
| B．Wave energy is so clean that it doesn’t create the same amount of pollution as other energy sources． |
| C．Wave power affects fishing and boat traffic． |
| D．Wave power may affect marine animals． |
| A．finding more new energy sources is not necessary because of wave energy |
| B．wave energy is a resource that will never run out and is used all over the world |
| C．wave power is not quite perfect for creating energy around the world |
| D．wave power doesn’t create any pollution |
| A．regrets | B．adventures | C．disadvantages | D．difficulties |
| A．How to Get Electricity by Waves | B．The advantages of Wave Energy |
| C．Can Waves Make Electricity? | D．The Disadvantages of Wave Energy |

This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

People tend to live up to expectations．We get out of life just about what we put into it．Our environment becomes a mirror of our spirit, our attitude, and expectations．If we set a great goal, we get great results．If we have a fair goal, we accomplish fair results, and if we have a poor goal, we accomplish poor results．The world will give you back what you expect, so expect the very best．Don"t be defensive or doubtful．Nothing changes unless you do．Before you can do something, you"ve got to be something．Know that you have worth and value．Show that to the world．
Treat everyone you come in contact with as the most important person in life．It will build self-esteem （自尊心）．Smile! You"ll be rewarded with a returned smile．Don"t react to others rudely．Forgive everyone who ever hurt you．Then, forgive yourself．Keep yourself healthy．Exercise．Eat a proper diet．Display an attitude of confidence．
Develop these good habits and your expectancy will be rewarded by successes．This attitude will put you into that group of people who are truly successful, because you will know and understand how an expectant attitude enhances （提高） every aspect of your life．
小题1:According to the author, we are likely to achieve success if we____．
| A．take a positive attitude |
| B．hold on to our dreams |
| C．have a good opportunity |
| D．show gratitude every day |
| A．success mainly depends on your efforts |
| B．our environment reflects what we think |
| C．the greater our goal, the better results we will get |
| D．it is our determination that decides our future |
| A．building self-esteem is important |
| B．we should treat everyone else fairly |
| C．if treated kindly, others are friendly |
| D．it makes good sense to forgive others |
| A．share his view point about life |
| B．offer advice on confidence building |
| C．suggest some ways to acquire success |
| D．stress the importance of positive attitude |
Whichever theory it may be, studies find, the cells have a poor grasp of longer interval．Time does seem to slow during an empty afternoon and race when the brain focuses on challenging work．Stimulants （兴奋剂）, including caffeine, tend to make people feel as if．time is passing faster; complex jobs, like doing taxes, can seem to drag on longer than they actually do．And emotional events — a breakup, a promotion, a transformative trip abroad —tend to be sensed as more recent than they actually are, by months or even years．In short, some psychologists say, the findings support the philosopher Martin Heidegger" s observation that time "persists merely as a consequence of the events taking place in it．"
Now researchers are finding that the opposite thing may also be true: if very few events come to mind, then the sense of time does not persist; the brain shortens the interval that has passed．
In one classic experiment, a French explorer named Michel Siffre lived in a cave for two months, cut off from the rhythms of night and day and man-made clocks．He appeared then, convinced that he had been isolated for only 25 days．Left to its own devices, the brain tends to shorten time．
In earlier work, researchers found that a similar case at work in people’s judgment of intervals that last only moments．Relatively infrequent stimuli, like flashes or tones, tend to increase the speed of the brain" s internal pacemaker．
On an obvious level, these kinds of findings offer an explanation for why other people" s children seem to grow up so much faster than one"s own．Involved parents are all too well aware of first step in their own children; however, seeing a cousin"s child once every few years, without bothering memories, shortens the time．
小题1:What can we infer from the first paragraph?
| A．Scientists have agreed about how the brain records time． |
| B．Scientists all think that some cells record the intervals of time． |
| C．Scientists haven"t agreed on how the brain records time． |
| D．Scientists all hold the theory that neural processes are an inside clock． |
| A．make the intervals of time long |
| B．make the intervals of time short |
| C．keep a state of rest |
| D．stop working |
| A．Michel Siffre didn" t think he had stayed in the cave for as long as two months． |
| B．Parents tend to think their own children grow faster than others． |
C．Michel Diffre actually stayed in  the cave for twenty-five days． |
| D．Children usually bring bad memories to their parents． |
| A．Social news | B．Community activities |
| C．Science | D．Children s life |
