An artist in Oakland, California isusing his skills to help the homeless. Greg Kloehn builds very small shelters that make life on the streets a little more comfortable. The structures offer the homeless some safety and protection from bad weather. Each little house also has wheels on the bottom so it can go wherever its owner goes.

    Greg Kloehn has given away at least 20 tiny houses. Several are on the roadside near an active railroad. On a recentday, Mr. Kloehn stops at one to visit Oscar Young. The two men hug. Inside his little shelter Mr. Young gets relief from cold nights on the streets. Mr. Kloehn also visits Sweet-Pea, another friend who also lives in one of the little homes the artist built. She says it keeps her safe and protects herbelongings.

    In the mornings, Mr. Kloehn searches the streets for building materials. He gathers what he can and takes it to his studio. There, he puts the houses together. Empty coffee bags become roofmaterial. A washing machine door and refrigerator part become windows. Nails, screws and the sticky glue hold all the pieces together. The artist also attaches a small electrical device to the house. The device is powered by the sun.

    Some of the people living on the streets once had normal houses of their own. But some of the people say they have learned to live with less and they are thankful to that man.

    Mr. Kloehn says his work is not a social project. He says he is just someone using his skills to help his homeless neighbors.

    Food production does great harm to our environment. There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants. Some procedures require the consumption of large amounts of fossil fuels, such as the transportation and storage of food products. Other factors that cause great damage to our environment include the overuse of fresh water.

    The production of beef is more damaging to the environment than that of any other food we consume. Raising large numbers of cattle requires the production of large amounts of food for the animals. It's estimated that producing one pound of beef requires seven pounds of feed.

    Land use is also a problem. If the cattle are free-range cattle, large areas of land are required for them to live on. This has led to disastrous forest cutting and the loss of rare plants and animal species, particularly in tropical rain forests in Central and South America.

    Another problem specific to beef production is methane emissions (甲烷排放). Although many people are aware of the damaging effects of carbon dioxide, they don't realize methane's global warming potential is 25 times worse, making it a more dire problem.

    Unfortunately, beef consumption is growing rapidly. This is the result of simple supply and demand factors. Specifically, there are two main causes of demand that are encouraging the production of more supply. First, the increase in the world population means there are more people to consume meat. The second factor is socioeconomic advancement. As citizens in developing nations become financially stable, they can afford to buy more meat.

    Therefore, one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.

    Personal computers and the Internet give people new choices about how to spend their time.

    Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.

    E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren't necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she'd been born before electronic mail became such a practical tool.

    The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun, see a great movie perhaps-and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story.

    With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.

    E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.

    We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don't take the place of any of the old ways.

    In Europe, there is no escape for those who do not appreciate art and architecture(建筑). It is a heaven for people who want to feel like they have been transported to famous historical time periods from America. For me, Europe was a complete contrast from America. London and France had a more royal feel than New York, and Rome felt more ancient. I wasn't just on a different continent; it felt like I was in a different century.

    My parents and I visited London, Paris and Rome this summer in celebration of the end of my high school experience. It was supposed to be a break from a life as busy as a bee in New York, the constant stress, the crowded subway rides, and the weary body that had accompanied me for the last four years. It was an opportunity to appreciate Europe the way I couldn't do it just by reading history books.

    My favorite parts of London were the Tower of London and the Churchill War Rooms. As a site of past executions(刑场), the Tower of London displayed punishing devices from the 16^th and 17^th century and told stories of various members of the royal family who had ever been imprisoned in the tower, some even imprisoned by their own family members when they were seen as a threat to the crown. Besides that, I also got to see the royal family's crown jewels, amazingly beautiful.

    The Churchchill War Rooms, though very different from the Tower of London, were also spellbinding from a historic perspective. I am not a history fan, but I enjoy museums, and I took fancy in the Churchchill Museum inside the War Rooms that detailed the events of Churchchill's life and World War II. Everything I saw in it built up his life from his childhood to his last years, creating a three-dimensional Churchchill in my mind who was a person just like myself. He longed for more, he made mistakes, he experienced loneliness and sadness. But he had also done some remarkable things like uniting Britain during World War II.

    Our rewarding trip ended in Rome a couple of days later.

Doing crosswords(纵横字谜) is a fun way to kill the time and can also be educational. Difficult crosswords may leave you confused as you have no ideas on how to solve them sometimes. To perform well in this game, you need to have enough knowledge of different fields. If you are unable to do them and you have access to the answers, it is not generally considered cheating to look up an answer or two. However, in some cases, it does not follow the rule.

A crossword should not include someone else's answers, so even a quick look at a fellow student to complete a crossword would not be fair. Generally, you wouldn't have access to the answers.

Additionally, some crossword competitions should not be connected with cheating. Again, in such a situation, you usually won't have access to the answers. Turning to the Internet or referring to(查阅) any books of crosswords for answers is also unfair, since some people will complete the crosswords strictly with their own knowledge.

If you are not in a competitive environment, the check of a word can actually be an opportunity to learn how to become better at crosswords. Through looking up the answers (Although sometimes considered as cheat.), you can memorize whatever facts or word definitions (定义) you must look up. This will help you avoid the need to cheat in the future.

Some argue that cheating on crosswords is always wrong, and you're only cheating yourself if you are looking up the answers. It could be argued instead that cheating on crosswords that are done for fun or enjoyment can actually be an opportunity to benefit yourself because you're learning something new. Just don't forget to mention that you actually did cheat a little. Being honest is of great importance both to you and the other competitors.

It can be helpful to buy books of crosswords that have several different difficulty levels. If you are new to doing crosswords, you might want to put off working on crosswords until you are more confident in your skills.
