We can have conflicts with our important persons like friends, relatives, workmates, etc. But the conflict doesn't necessarily mean that the relationship will be destroyed. In fact, sometimes conflict helps people to let out their silent feelings, allowing them to free their suppressed emotions. However, when in a conflict, we usually get angry and say or do things which aren't linked to the problem at hand. Therefore, it is important that we should try to avoid conflicts through effective communication.

    In a heated argument, we usually say things that aren't related to the real problem, and even use rude words to make sure we gain an advantage over the other persons. Then the whole situation goes badly. So we should not separate(隔离) the root cause of the problem and build our discussion around it. This ensures that there are no rude remarks and the situation moves in a positive direction.

    It's easy for us to think we're right and if something isn't working out, it surely must be someone else's fault. However, if you aim to solve a conflict, first of all, you should show some respect and allow the other persons to express themselves. Using remarks like, "I understand your concern on this "or "I know you're right at your end", would make the other persons feel more appreciated.

    Sometimes some people get too excited and may behave in the wrong way or say something others may not appreciate. This can cause a worse situation. Actually, they should control their emotions and keep calm. This has to be learned through self-control and observing behavior of other people.

    The tips mentioned above are useful for most situations. However, we don't rule out the possibility that there are some people who always want to create some sort of trouble for others. You can tell them from others, and putting in an effort to resolve a conflict with them may just not be a wise idea. The best way to deal with these people is to forget them. A famous saying can help you and that is: "You should never fight with a pig; you both get dirty and only the pig likes it."

    Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word “green” means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 15th century, a greenhorn was a young cow or an ox whose horns(角)had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18th century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20th century. A person with a green thumb can make plants grow quickly and well.

    Green is also the color used to describe the powerful feeling , jealousy(嫉妒). The green-eyed monster （怪物）is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants. For example, a young man may suffer from the green-eyed monster if you get a pay rise and he does not.

    In most places in the world, a green light means to move ahead. In everyday speech, a green light means agree to continue with a project.

For your next out-of-this-world vacation, you now have the option of literally going out of this world—-but it'll cost you $ 40 million. Then again, can you really put a price tag on having the time of your life? According to a new report from Popular Mechanics, Russia is looking to build a luxury hotel in outer space. There you will wake up to a breathtaking blue planet—--the earth! The hotel is expected to be stationed on the International Space Station (ISS).

While space tourism itself isn't exactly a novel idea, the notion of building a hotel out there hasn't been raised before. Really, other companies are still focused on the transportation part of the puzzle—-after all, a trip to space is enough for most folks.

    According to Popular Mechanics, the hotel will include a luxury orbital suite with big windows, personal hygiene(卫生) facilities, exercise equipment, and yes, WiFi. Because if you can't share your experience on social media, did it really even happen?

    Of course, the reasons behind the hotel aren't just for fun and games. Apparently, space tourism might be able to help the Russians pay for another module to add to the International Space Station. Russian space contractor RKK Energia is currently building the first such module, which will give scientists a laboratory and power supply station from which to conduct tests.

    If any of this is going to happen, however, Russia is going to have to hurry. With the ISS expected to be out of use in 2028, there's little time to build the hotel and find wealthy tourists to actually buy a trip into outer space.

    So if you've recently come into a fortune and are interested in what could be the time of your life, ISS is calling your name.

    Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. Americans won't live without cars!

    Most Americans would find it hard to think what life would look like without cars. However, some have realized the serious problems of the air pollution that is caused by the car.

    The polluted air becomes poisonous and dangerous to health.

    One way to get rid of the polluted air is to build a car that does not pollute. That's what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

    Another way is to take the place of the car engine by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.

    To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean.

    But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.

    Although cars have led us to a better life, they have also brought us new problems.

    Brazil, the largest country in South America, is famous for the Amazon rainforest and soccer. But on the hottest days, people travel there for another reason – the Carnival. Full of excitement and fun, the Carnival is held annually in February or March. This year, the celebration runs from March 2^nd to 9^th.

    It is a wild festival of food, music and dance. The word "Carnival" comes from the Portuguese "Carne Vale", which means "farewell to meat". In the early 1600s, the Portuguese brought European traditions to Brazil. Then they started their own carnival with dances and music, which were inspired by black people brought there by the slave trade.

    With its beautiful floats (花车), attractive clothes and happy people, the Samba Parade is the most fantastic event of the Carnival. The Sambadrome is a special stadium for the Carnival in Rio de Janeiro with 80,000 seats where people can sit and enjoy the festival. Samba is said to be the soul of Rio. "This is where the passion for samba lies – the atmosphere is electric as even the oldest men and women sing and dance to the music," travel guidebook Lonely Planet noted.

    Top samba schools stand out in the main parade, with fantastic parades of floats and thousands of dancers. The parade goes on until dawn. The schools base their performances on certain themes from Brazilian history or on social and environmental problems, such as that of the Amazon rainforest.

    Besides fun street parties, colorful costumes and energetic music, Carnival also offers plenty of tasty street food, such as Quindim – a dessert made of egg yolks and sugar.

Overall, it is traditionally a time to go a bit crazy with eating, dancing and dressing up.

    Anyone who has ever volunteered for any cause can tell you that in the end, they felt that they gained more from the experience than they gave. This is true for most examples of reaching out to help others. We find that we gain new understanding about not only those we help, but ourselves as well. Stressing the importance of helping others in martial arts students will benefit them both inside and outside of the class.

    Helping others strengthens families. Families that practice the belief of working together and helping each other prepare their children for the concept of teamwork outside of the home environment. By learning to help around the house through activities such as household jobs, baby-sitting and keeping a tidy bedroom, children learn valuable lessons that they carry with them to their future relationships.

    By helping others outside of the home environment, valuable friendships can be developed. When we learn to reach out to others and give off our time and talents we find that our friendships grow, which in turn is a benefit to our lives. Martial arts training supports this by exposing students to people of various backgrounds and beliefs that gather for a common goal and to help each other. Any time a group of people are working toward a common goal, team spirit surely forms. When we help each other in the martial arts setting and in every area of our lives, a friendship is formed that promotes teamwork.

    The most important thing to realize is that it does not take a lot to make a lot happen. Little things can make a big difference in the area of helping others. Simple gestures of kindness and support given frequently can build a strong base for the growth and development of each individual which leads to the success of all.
