Do you want to take time to get in touch with yourself, your feelings, your dreams, and a good, healthy life? Here are some tips:

    {#blank#}1{#/blank#} Sometimes it seems as if our culture has begun to view the need for sleep as a sign of weakness. But your body was genetically(基因地) programmed to spend a third of its life on sleep, and this affects thinking, memory, growth, your immune(免疫的) system and even your weight.

    Begin the day in thankfulness. {#blank#}2{#/blank#} Name each person and hold them in your thoughts. The sense of thankfulness you experience will set a peaceful tone for the entire day, and reduce a day's stress that can lead to sleeplessness that night.

    Strike a balance. {#blank#}3{#/blank#} Think about tai chi, prayer, yoga(瑜伽)—any daily activity that allows you to develop a peaceful center and a sense of balance.

    Play with friends. The "tend and be friend studies", as they are called, conducted by UCLA researcher, Shelly Taylor, Ph.D. indicate that when women are stressed, they tend to their children and play with other women. {#blank#}4{#/blank#}

    Use guided imagination. {#blank#}5{#/blank#} The tone of your voice, pacing, music, and pictures will persuade your nervous system that it's time to calm down.

    Growing roses is quite a difficult task without knowing the right way. If you are attracted by the beauty of roses and need some tips for growing them, read on for some tips about taking care of rose plants.

● You have to buy a good plant, preferably around two years old.

● While most rose plants can tolerate around six hours of sunlight every day, some varieties need eight hours of sunlight exposure. The shade-loving roses need only four hours of sunlight.

● You will have to soak(浸泡) the roots overnight, before planting. If you plant it in a container, then the watering should be done daily, whereas garden roses need water once or twice a week.

● The next point is the application of fertilizers（肥料）, which is mainly needed by rose plants in containers. Most of the varieties do not need fertilizers, as they can feed on the nutrients that exist in the soil. There is no need of fertilization during November and December, and the frequency of fertilization can be reduced during the summers, especially after April. It can be restarted in September and has to be increased during the growing periods.

● Cutting the stems promotes the growth of the plant and also aids flowering. It should be done regularly to remove dead or diseased leaves and stems.

Rose plants can be successfully grown by beginners too! With some care and consideration, all your efforts would definitely be worth it once you smell the fragrance of beautiful roses. 

    Body language is the quiet, secret and most powerful language of all! It speaks1 than words. According to specialists, our bodies send out more 2than we realize. In fact, non-verbal communication（非言语交际）takes up about 50%of what we really 3. And body language is particularly 4 when we attempt to communicate across cultures. Indeed, what is called body language is so 5 a part of us that it's actually often unnoticed. And misunderstandings happen as a result of it.6, different societies treat the 7 between people differently. Northern Europeans usually do not like having 8 contact（接触）even with friends, certainly not with9. People from Latin American countries, 10, touch each other quite a lot. Therefore, it's possible that in 11, it may look like a Latino（拉丁美洲人）is 12a Norwegian（挪威人）all over the room. The Latino, trying to express friendship, will keep moving 13. The Norwegian, very probably seeing this as rudeness, will keep 14 which the Latino will in return regard as 15.

    Clearly, a great deal is going on when people 16. And only a part of it is in the words themselves. And when partners are from 17 cultures, there's a strong possibility of 18 But whatever the situation, the best 19 is to obey the Golden Rule: treat others as you would like to be20.

    We can video chat with astronauts aboard the International Space Station and watch live footage from the frozen heights of Everest. But communicating with a submarine (潜艇）or a diver is not so easy. The lack of practical methods for sharing data between underwater and airborne devices has long been a frustration for scientists. The difficulty stems from the fact that radio signals work perfectly in air travel but poorly in water. Sonar (声呐）signals used by underwater sensors reflect off the surface of the water rather than reaching the air.

    Now, researchers at MIT have developed a method with the potential to revolutionize underwater communication. "What we've shown is that it's actually feasible to communicate from underwater to the air," says Fadel Adib, a professor at MJT's Media Lab, who led the research.

    The MIT researchers designed a system that uses an underwater machine to send sonar signals to the surface, making vibrations (震动)corresponding to the ls and Os of the data. A surface receiver then reads and decodes these tiny vibrations. The researchers call the system TARF. It has any number of potential real-world uses, Adib says. It could be used to find downed planes underwater by reading signals from sonar devices in a plane's black box and it could allow submarines to communicate with the surface.

    Right now the technology is low-resolution. The initial study was conducted in the MIT swimming pool at maximum depths of around 11 or 12 feet. The next steps for the researchers are to see if TARF is workable at much greater depths and under varying conditions—high waves, storms, schools of fish. They also want to see if they can make the technology work in the other direction— air to water.

    If the technology proves successful in real-world conditions, expect "texting while diving" to be the latest underwater fashion.

    Life is difficult.

    What do you think about life? Maybe most people say that life is difficult. But life is no longer difficult once we truly understand and accept it. Most people do not fully see this truth. Instead, they complain about their problems and difficulties as if life should be easy. It seems to them that their difficulties represent a special kind of suffering especially forced upon (强加于) them or their families, their class, or even their nation.

    What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.

    Yet, it is in this whole process of solving problems that life has its meaning.

    Problems are the serious test that tells success from failure. When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, "Those things that hurt instruct." It is for this reason that wise people learn not to fear but to welcome the pain of problems.

Big Stuff

Do you know what is the tallest building in the world and where the tallest Ferris wheel is? Have you heard of the world's steepest roller coaster? Have you seen the biggest monster truck? Here are some of the most huge things on Earth.

A Towering Achievement

Burj Khalifa, a tower in Dubai, United Arab Emirates, is the world's tallest structure. The 162-story building, which opened in 2010, stands over 2,717 feet tall. Seen from above, the tower has a Y-shaped design. Its three tall, narrow wings are joined in the middle. Like the legs of a tripod （三脚架）, each wing is supported by the other two.

A Wheel Winner

About 15 miles from the world's tallest building stands the world's tallest Ferris wheel, Ain Dubai. Also called an observation wheel, Ain Dubai stands 820 feet tall. Each of the 48 cabins can carry 40 people for spectacular views of Dubai, United Arab Emirates. Before construction, support columns had to be driven 115 feet down through the earth to reach bedrock.

Extreme Ups and Downs

The world's tallest roller coaster is Kingda Ka at Six Flags Great Adventure. At 456 feet, the peak of the ride towers over nearby Jackson, New Jersey. A 500-foot-tall crane was needed to place the final section at the top. Like many weight-bearing structures, the tower makes use of the most stable geometric （几何的） shape, the triangle.

A Monster of a Truck

Designed and built by business owner Bob Chandler, Bigfoot 5 has held the record for the world's biggest monster truck since 

1986. Other trucks, including Bigfoot models, have been designed to perform better in competitions. But Bigfoot 5 still stands above the crowd, thanks to its 10-foot-tall tires. The tires were originally designed for equipment that drives on Alaska's snowy tundra.
