Do you want a bit of an adventure? Would you like to discover all the corners of the UK, or travel abroad? Maybe you have never tried the motorhome lifestyle before. Well, read this article and you will know why a motorhome is a good choice.

    Nothing is better than a motorhome. It has so many uses that it is considered the most versatile vehicle and it is also very comfortable. If you are thinking about hiring a motorhome this summer, then the best choice is to book it early, especially if you are considering the school holidays. The motorhome hire service is very seasonal and motorhome hire companies will never have extra vehicles available in the summer months.

    There are a lot of companies throughout the UK, and some of the big ones have motorhomes spread all over the country. At present, the largest network for motorhome hire is provided by Motorhome which is based in Cambridge. If you are in the UK, you may phone 0800612-8719 for details of its motorhome hire information. Motorhome has a network of over 500 vehicles all over England, Scotland and Wales.

    Most people wishing to hire a motorhome are families that are looking for an alternative to a European package holiday, especially as flying now has become more expensive, and is considered to be environmentally unfriendly. There is no doubt that the idea of no-fly holidays is going to become more popular as fewer people think it is safe to fly. This explains why more and more people are choosing to hire a motorhome for their holidays.

    First it was worry about second-hand smoke, now there's major concern over third-hand smoke which gets into hair, clothes, furniture or a car rather than directly from a cigarette or someone breathing it out.

    To be honest, I've always been worried about the health dangers of this even though I didn't know it had a name. My worry made me reluctant to let smokers hold my babies even though they didn't smoke in my house.

    Tests for its effects have been only carried out on mice, but I don't think they can be ignored. Researchers at California University last month suggested third-hand smoke (THS) could cause type 2 diabetes, liver and lung damage.

    They analyzed how people are affected by taking in smoke from another person's clothing, hair, home, or car. They say they can see an impact on the brain and liver. Lead author Manuela Martins-Green said: “Our goal was to decide the smallest amount of time required to cause physiological changes in mice when they are exposed(暴露) to THS.” This was done using an exposure system that is the same as human exposure.

    “We found THS exposure as early as one month caused liver damage. Exposure for two months lead to further molecular(分子的) damage, and at four to six months caused even more such damage. We also found the mice showed insulin resistance（抗胰岛素） after long-term exposure.”

    “THS is a hidden danger, a silent killer. Pollutants can be absorbed through the skin and through breathing.”

    “Although our research was not done on humans, people should be aware that hotel rooms, cars and homes that were used by smokers are very likely to be polluted with THS.” Martins-Green believes most people don't know they're being exposed to THS, or don't believe in the damage it can do.

    THS toxins(毒素) remain on surfaces for many years, and resist even strong cleaning agents.

    People who like travelling have their reasons. They believe that travelling can help them expand their field of view, especially in the geographical and historical sense. They also think that touring will give them more chances to enjoy different kinds of food and experience new things that would never be brought by other activities. But those who dislike travelling also have some reasons.

    Travelling, in my opinion, does more good than harm. Most importantly, it broadens  (使扩大) our mind. We can get in touch with other civilizations (文明), cultures, customs and ideas.

    Through history, most people travelled because of necessity (必要性)—not for pleasure. People travelled just in order to remain alive. They searched for food to eat or places to live in. They sometimes ran away from enemies. This is not to say that no one ever travelled just for the fun of it. In ancient times, for example, rich Romans travelled all the way to Greece to take part in the Olympic Games, and festivals. Of course, some people decided to travel just out of curiosity (好奇心). They wanted to find out what it looked like beyond the horizon (地平线). Also business travel has been going on for centuries. Traders could not only make money but also learn to speak several languages and be introduced to different cultures.

    So, travelling does enrich our mind and draw new ideas to us. There is no doubt that we can get much from it.

    Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word "diet" everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.

    Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word "diet" in food labels.

    On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

    The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.

    Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.

    In the future we might live somewhere other than Earth, like Mars. Some people ask how this will be possible. Well, Mars is in fact a lot the same as the earth. The days are almost the same as those on the earth. However, the two planets vary in temperature.

    Since there is mostly carbon dioxide on Mars, it would be quite difficult for a human to just land on it. So, special types of homes and space suits have to be designed. The space suits should be almost like the ones astronauts use now, and except that they have to be warmer so that the astronauts can survive the cold temperatures. The space suits must also be able to withstand (承受) high pressure and potentially dangerous radiation that can kill.

    The houses should be similar to our homes today with a slight difference. All of the houses and other buildings should be built inside a large dome (圆顶状物) or bubble. The domes should be made out of glass, and would also be able to prevent radiation from affecting the people inside. The domes will be connected to a machine (like plants which turn carbon dioxide into oxygen).

    With Mars' population growing, how would the people on its surface get fresh food and water? Just like humans use domes, they can also use domes to grow plants. However, the domes where the plants are grown must be built to expand. Once we upgrade the domes to a larger size then we can grow more food by cultivating (种植) more plants. To get the food or come in connect with other domes, there will be long narrow tunnels like roads that connect to each dome separating them by several doors so that the pressure in each dome can remain the same.

    On Mars, so many other things are available to us. As humans, we can have access to rare and fairly expensive metals that aren't very easy to get hold of on Earth, and a colony on Mars enhances (提高) our chances of finding these metals. So when someone here on Earth says that going to Mars is impossible, please tell them that they'll never know it until they try and they may try very soon. After all it's our future. Why not make it on Mars?

Bees (蜜蜂) touch our lives in ways we may not realize. They are responsible for as much as one third of the food that we eat, and even play a role in growing the cotton (棉花) used in much of our clothing. {#blank#}1{#/blank#} Here's how you can help:

1. Plant more flowers

Bees depend on garden flowers to ensure they have different kinds of diet. By planting flowers in your garden you can create a pleasant place for bees. {#blank#}2{#/blank#} Another idea is to add hanging baskets of flowers next to your front door.

2. Find a space for a beehive (蜂窝) in your garden

Many would-be beekeepers find it difficult to find a safe space for their bees. If you have some space, contact your local beekeeping organization. {#blank#}3{#/blank#} You will be surprised what a difference a beehive will make to your garden.

3. Give bees water

{#blank#}4{#/blank#} They use water to produce food for their bee families and control the temperature in their hives. Bees look for a clean source of water. Leave out containers filled with clean water in your outdoor spaces and refresh them often.

4. Be bee friendly

Bees are good neighbors, and only sting (蜇) when they feel threatened. Beekeepers wear protective clothing when they are dealing with bees. If a bee flies in front of you when unprotected, do not flap (拍打) your hands. {#blank#}5{#/blank#} The bee will soon lose interest.
