【推荐2】Trust is important to life. Trust affects how you see the world, how safe you feel and how you approach new people and situations. It affects whether you are willing to go the extra mile for a friend, relative, co-worker, even someone you’ve never met. If trust levels are high, you will feel relaxed and accepted.     1     Here is a checklist for you to build trust in your personal life.

Learn to determine who deserves your trust. The unfortunate fact is that not everyone can be trusted. It is not a good idea to trust everyone your meet or share personal information about yourself too freely.     2     Check out the person’s story and background if possible. Watch for signs that someone may not be trustworthy, such as avoiding your eye contact or making conflicting statements.

    3     You build strong relationships by being a trustworthy listener. When someone shares their personal information, don’t share it with others. If a friend or relative tells you something personal about marriage, or co-worker shares something private about a work issue, resist the urge to tell others about these private conversations.

Be honest. Honesty is the basis of any relationship. Be true to your words and keep your promises. Share honest information, even if it’s to your disadvantage. Don’t hide things from those you want to build a relationship, and don’t lie.     4    

Work at building trust when there is a problem. When there are disappointments, the only way to regain lost trust is to work at it. If you feel betrayed or taken advantage of, talk with the person who lets you down.     5     The longer you wait to talk about a problem, the bigger the misunderstanding becomes. Find small ways to trust the person again. When you see small commitments being met over time, it’s easier to believe that the lager ones will be met, too. Be realistic and know that it can take a long way to rebuild trust.

【推荐3】The youth are like the early spring, the morning sun and the budding(萌芽的) flowers. There’s no denying that youth is the most valuable time of life. During this period of time, habits and interests that will continue for the rest of your life are formed and developed.     1     — so the earlier you cultivate (培养) the youth spirit, the more likely you will achieve success in life.

Be self-reliant and self-motivated. Sure, you might have parents and friends to help you, but ultimately, you must rely on yourself.     2    , which enables you to get through the challenges of life. No one can force you to get good grades or get an excellent job.     3    . Only you can be the author of your own life.

    4    . Train yourself to be strong when times get tough. Anything worth doing isn’t easy. Tell yourself that you can make it whatever obstacles (障碍) stand in your way as long as you won’t give up. After all the trials and errors, you will thank perseverance for guiding you to success.

Work hard. As Albert Einstein once put it, “Genius is one percent inspiration, ninety-nine percent perspiration (汗珠).” Young and talented as you are, without diligence, you can hardly bring out your potentials. As a result, don’t waste time admiring others’ success or daydreaming.     5    .

In conclusion, the prime of youth, the most vibrant and energetic period in life, is also the most fleeting (转瞬即逝的). Let’s capture the spirit of youth and turn our dreams into reality.

【推荐1】California’s beaches are world-famous. But new research indicates many could disappear by the century’s end due to erosion (侵蚀) from sea level rise.

“The shoreline is probably going to move landward about 30 meters or more for every meter of sea level rise,” says Sean Vitousek, lead author of the report. “When you get into three meters of sea level rise, you’re talking almost 300 feet of erosion.” Using nearly four decades of satellite images and computer models, the researchers say 25 to 75 percent of California’s beaches may become completely eroded by 2100.

So how much sea level rise will the state get in the coming decades? Anywhere from two to 10 feet, depending on two major factors. One is ocean warming, which causes the water to rise. Another is the melting (融化) of land ice.

“The ice in Greenland holds about seven meters of sea level and the ice in Antarctica holds about 70 meters of sea level. So the big uncertainty is really understanding what the global temperature is going to be like and how much of that ice melts,” Vitousek says.

The findings will help state and local officials plan for the future and look for ways to protect coastal communities, roads and railroad tracks.

Vitousek thinks a lot about possible solutions for problems like erosion. He says the most successful long-term solutions will likely be ones that work with nature. Some short-term solutions, such as trucking in more sand, can be expensive. A medium-term solution is building barrier islands off the coast to weaken and slow incoming waves. They will also provide habitat for wildlife but require maintenance (维护). The best long-term solution is to fight climate change.

“The ocean is going to do what the ocean is going to do and we can stop it to a certain degree. But we’re nowhere near as powerful as the ocean, so we’re under its cover,” says Vitousek.

【推荐3】Solar (太阳能) water heaters can use energy from the sun to heat water. They are used around the world. The solar water heater is based on a design developed some years ago in Afghanistan. Since then, it has been built and used in many countries. It can heat seventy liters (升) of water to 60℃. It can do this between sunrise and noon on a clear day with an average temperature of 32℃.

There are two parts of the solar water heater. One part, the collector, is made of a metal plate painted black. This metal surface, placed in contact with the water, will heat the water. Black-painted surfaces that receive the sun’s heat become hotter than those of any other color. Metal plates that have raised parts on the surface work better than those without them. Once the water is heated, it is kept hot with special material, which allows the water to stay warm for a long time.

The second part of the solar water heater holds the water for the system. This water tank (水箱) can hold about one hundred liters of water. Two rubber pipes are connected to the water tank. One pipe lets water go into the system. The other lets water go out.

When the water heater is working correctly, water will flow from the tank to the collector and back again. You can use the hot water at the top of the tank for washing and cleaning. This solar water heater is easy to build and operate. It will last about two years before the rubber pipes need to be replaced.
