Living and dealing with kids can be a tough job these days, but living and dealing with parents can be even tougher.

    If I have learned anything in my 16 years, it is that communication is very important, both when you disagree and when you get along. With any relationship, you need to let other person know how you are feeling. If you are not able to communicate, you drift apart. When you are mad at your parents, or anyone else, not talking to them doesn't solve anything.

    Communication begins with the concerns of another. It means that you can't just come home from school, go up to your room and ignore everyone. Even if you just say “Hi”, and see how their day was for five minutes, it is better than nothing.

    If you looked up the word “communication” in a dictionary, it would say “the exchange of ideas, the conveyance （表达）of information, correspondence （通信）, means of communication: a letter or a message”. To maintain (保持) a good relationship, you must keep communication strong. Let people know how you feel, even if it's just by writing a note.

    When dealing with parents, you always have to make them feel good about how they are doing as a parent. If you are trying to make them see something as you see it, tell them that you'll listen to what they have to say, but ask them politely to listen to you. Yelling or walking away only makes the situation worse.

    This is an example: one night, Sophie went to a street party with her friends. She knew she had to be home by midnight after the fireworks, but she didn't feel she could just ask to go home. That would be rude. After all, they had been nice enough to take her along with them. Needless to say, she was late getting home. Her parents were mad at first, not when Sophie explained why she was late, they weren't as mad and let the incident go. Communication is the key factor here. If Sophie's parents had not been willing to listen, Sophie would have been in a lot of trouble.

    Communication isn't a one-way deal: it goes both ways. Just remember: if you get into a situation like Sophie's, telling the other person how you feel-listening is the key factor to communication.

Electric Cars

    Where do cars get their energy from? For most cars, the answer is petrol. But some cars use electricity. These cars have special motors that get their power from large batteries.

    Most people tend to think of electric cars as a new invention, but they have been around for a long time. They were popular when the technology for petrol engines was not very advanced. Recently, electric cars have again become popular because people want cars that pollute less.

    Electric cars are better than petrol cars in several ways. The biggest benefit is reduced pollution. In areas where there is a high percentage of electric cars, there is less pollution. But it is important to understand that electric cars still cause pollution. Remember that the electricity to power electric cars has to come from somewhere, which is most likely a power station. Unless these power stations run on solar or wind energy, they are most likely burning coal and oil to make electricity. The second benefit of electric cars is a reduction in the dependence on foreign oil.

    There are several countries, including the United States, which don't want to rely on oil coming from other countries to power their transportation systems. They want the power to come from within their country, and since electric cars can run on electricity from coal or nuclear power stations, there is less of a need to import oil.

    Despite the benefits of electric cars, there are some problems with them as well. One disadvantage is that electric cars are more expensive than petrol cars. This is mostly due to the high cost of the batteries these cars need. Electric cars run on batteries, just like a mobile phone does. But unlike a mobile phone, you cannot charge your electric car's battery by plugging it into a wall. They need to be charged in special places. Now, there is a lack of places where people can charge the batteries. Another problem is that electric cars cannot travel as far as petrol cars. Some people are afraid that the battery will run out of electricity (and the car will stop) before they reach their destination.

    Despite these problems, many people, including automobile industry experts, believe that the percentage of electric cars will increase in the future.

    As is known to us, Washington University in St. Louis became the first college in the United States to ban (禁止) selling bottled water in 2009. Since then, more than a dozen small colleges and schools have done the same. The ban isn't because the schools don't want students to have easy access to water. Instead, the goal is to encourage students to bring reusable bottles to save money and, more importantly, to save the environment.

    Many people believe that producing and using bottled water not only wastes money but also harms the environment. They say that bottled water is unnecessary because public water supplies in the U.S. are among the best in the world. These people believe that water fountains and reusable bottles with easy access to filling stations are a better choice.

    But the makers of bottled water argue that plastic bottles make up a small portion of the nation's total waste. They say it's unfair to single out (单独挑出) their product when so many other items are packaged in plastic containers, and what's more, water is a healthy choice compared to some sodas and juices that are also sold at school.

    What do you think: Should sales of bottled water be banned from schools? We want to hear your opinion. Write a 200-word response. Send it to tfkasks4you@timeforkids.com. Your response may be published in a future issue of Time For Kids. Please include your grade level and contact information for your parent or teacher if you want your response to be published. The deadline (截止时间) for responding is August 31, 2012.

    As a college student, I have planned my future career goals. I would like to work as a sales assistant in a computer company, then a sales manager and finally boss of my own company.

    At the very beginning, I plan to find a job in a famous company producing computers, in which all the staff are fully happy at work and I can experience job satisfaction most of the time. Only such kind of company can provide me with good working atmosphere and eagerness to learn more so as to get well prepared for my future profession.

    At first I want to be a sales assistant and always keep myself busy working in and out of the company, such as, answering telephones, doing repair work, even cleaning the rooms. Although the salary may be low, I will seize every chance to learn from other staff. In my spare time, I will take some courses so as to get more qualifications and experience in this field. In three or five years, I am determined to become a sales manager who is responsible for the selling of the computers. I will interview as many customers as possible and do market research and improve our products. Meanwhile I will take care of my staff to make them eager to work to the best of their abilities.

    As is known to us, it is hard to manage a company, but I will make every effort to achieve my goal step by step, and I am sure "There is nothing difficult in the world if you put your heart into it."

    Triple Olympic and world sprint(短跑) champion Usain Bolt of Jamaica said on Monday he expects years of fast feats to ease doping doubts in athletics and has no plans to play American football.

    Appearing on ESPN programs and in light-hearted races outside the television sport network's studios, Bolt said he feels he must prove himself to a skeptical sports world in the wake of past doping scandals(诽谤).

    "I have to prove myself to the world that you can run fast without it," Bolt said.

    Bolt cited the speeds he and countryman Asafa Powell and American Tyson Gay have achieved without positive doping tests.

    "We just (have to) continue to run fast," Bolt said. "In a couple of years everyone will continue to watch again and have less doubts."

    Bolt won gold in the 100m, 200 and 4x100 relay in world record times at last year's Beijing Olympics and last month in Berlin set world records of 9.58 seconds in the 100 and 19.19 in the 200 and helped a relay title in a World Championships treble.

    "I want to be a legend in the sport. For me it's all a focus on winning championships after championships," Bolt said.

    "I don't consider myself a legend. When I defend my titles I will consider myself a legend."

    Bolt's defending of World and Olympic gold should be the feature attraction of the 2011 IAAF World Championships in Daegu, South Korea, and the 2012 London Olympics.

Robots have long been drawing inspiration from animals, with the creation of robot dogs or snake-shaped robots. And yet, the field of robotics is far less enthusiastic about the other kind of living things—plants. Barbara Mazzolai, an Italian roboticist owes this to a misconception about plant behavior: that they cannot move or think. "It's not true at all, " she says. To challenge this view, Dr Mazzolai and her team recently launched a machine called "FiloBot", a robot based on a climbing species. 

To survive, a climbing plant must switch between several different behaviors. In forest environments, it must first grow out of the soil and travel along the ground in search of a support to hold onto, such as a nearby tree. Once a support is located, though, the plant fixes itself around the object and then growing towards the light. To choose the best angle to grow upwards, a climbing plant uses its shoots(芽) to receive information about light and gravity. 

FiloBot has sensors on its main shoot. It can 3D-print its body with plastic and grow at a controllable rate. These functions, researchers found, enabled FiloBot to cross gaps, and find things to attach to. The lack of heavy on-board computing device means that it is light and requires minimal care, while its slow pace means that it doesn't disturb things around it, making it possible to move through a complex, unseen environment, or monitoring disaster sites. 

For now, FiloBot is still being tested. Its tendrils(卷须) have not left the laboratory. Still, it has already been employed in deconstructing plant behaviour. For example, it was long assumed that climbing plants find their supports by growing towards shade, though the exact mechanism was unclear. FiloBot could imitate this behaviour by detecting far-red light, which is typical of shaded areas, providing clues to how plants do it. 

Dr Mazzolai hopes that such projects will inspire other roboticists to take their cues from plants and develop completely new technologies.
