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.

    One day，Mr.Arnold was teaching a lesson，and things were going as normally as ever.He was explaining the story of mankind to his pupils.He told them that，in the beginning，men were nomads(游牧人)；they never stayed in the same place for very long.Instead，they would travel about，here and there，in search of food，wherever it was to be found. And when the food ran out，they would move off somewhere else.

He taught them about the invention of farming and keeping animals.This was an important discovery，because by learning to cultivate(耕作)the land，and care for animals，mankind would always have food steadily available.It also meant that people could remain living in one place，and this made it easier to set about tasks that would take a long while to complete，like building towns，cities，and all that were in them.All the children listening were attracted by this story，until Lucy jumped up：

    “And if that was so important and improved everything so much，why are we nomads all over again，Mr.Arnold？”

    Mr.Arnold didnt know what to say. Lucy was a very intelligent girl.He knew that she lived with her parents in a house，so she must know that her family were not nomads；so what did she mean?

“We have all become nomads again，” continued Lucy.“The other day，outside the city，they were cutting the forest down. A while ago a fisherman told me how they fish.Its the same with everyone：when theres no more forest left, the foresters go elsewhere，and when the fish run out, the fishermen move on.Thats what the nomads did，isnt it？”

The teacher nodded,thoughtfully. Really,Lucy was right. Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs，we kept developing it until the land was bare.And then off we would go to the next place！The class spent the rest of the afternoon talking about what they could do to show how to be more civilized.

    The next day everyone attended class wearing a green T-­shirt，with a message that said，“I am not a nomad！”

    And，from then on，they set about showing that indeed they were not.Every time they knew they needed something，they made sure that they would get it using care and control.If they needed wood or paper，they would make sure that they got the recycled kind.They ordered their fish from fish farms，making sure that the fish they received were not too young and too small.They only used animals that were well cared for，and brought up on farms.

    And so，from their little town，those children managed to give up being nomads again，just as prehistoric men had done so many thousands of years ago.

    If you choose a hot tourist spot for your holiday, you are likely to be drowned by a great number of tourists, noise and long lines. At this point you might wonder why you ever left home. Here are some tips to deal with crowds and avoid the trouble that might ruin your trip.

Book Tickets In Advance 

    Buy tickets online before you leave home, and skip the crowds and endless lines at your destination(目的地). Smart travelers can avoid the queue when visiting abroad with online ticket sales.

Talk To People

    You can ask the travel agency and the hotel for help. Ask questions, get maps, ask about taxis, restaurants and the sites you wish to visit. These people are experts and can save you lots of time trying to find things out for yourself.

Sign Up For Special Tours

    If there are any special events or tours being offered for your vacation, buy them in advance. Firstly they are usually cheaper bought in advance and secondly it makes sure you get booked in before they are sold out.

Visit During the Weekdays

    We all know that most sites and events are less crowded during the week than on weekends when people are off work and the kids are out of school. Flights are also usually cheaper on weekdays than they are on weekends.

Watch The Weather

    Mother nature controls a lot of what we do especially for outdoor activities. Check the weather forecasts and plan your indoor and outdoor activities according to the weather ahead of time.

    A heartbroken dog whose owner died two months ago is missing her so much that he attends services every day at the Italian church where her funeral was held, patiently waiting for her to return.

    Tommy, a seven-year-old dog, belonged to Maria Lochi, 57, and had been her faithful partner after she adopted him when she found him in fields close to her home. Mrs. Lochi adopted several dogs she found but friends said she developed a close friendship with Tommy and would walk to church with him every day, where he would be allowed to sit patiently by her feet.

    Father Panna said, “He's there every time I celebrate Mass and is very well behaved. He doesn't make a sound, and I've not heard one bark from him in all the time he has been in. He used to come with Maria and he was obviously devoted to her. I let him stay inside as he was always so well behaved and none of the other people ever complained to me. He's still coming to Mass even after Maria's funeral, he just sat there quietly. I didn't have the heart to throw him out. I've just recently lost my own dog so I leave him there until Mass finishes and then I let him out.”

    Tommy's been adopted by everyone in the village now and he is everybody's friend. Everyone looks out for him and leaves food for him, although it would be nice to find a proper home for him.

    The story of Tommy is similar to the 2009 Hollywood film Hachi which told of how a faithful Akita dog waits patiently for his master after he also dies. It was based on the true story of a Japanese Akita called Hachi, whose owner died in 1925 but for the next nine years he waited patiently at the railway station for his owner from where they regularly caught a train.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    “It's extremely important for us to think about this as a whole system and not just a bunch of individual components (零件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. “The added difficulty with such a project is that actually none of those components are off the shelf and so we have to make them all on our own,” he said.

    They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of individual components, each of which individually has to perform well, and then has to be matched well to everything it's connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    Wood says the design offers a new way to study flight mechanics and control at insect- scale. Yet, the power, sensing and computation technologies on board could have much broader applications (应用). “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

Insect numbers have decreased by half in some parts of the world due to climate change and intensive agriculture,a study has found.The combined pressures of global heating and farming are driving a "substantial decline" of insects across the globe,according to the UK researchers.

Lead researcher,Dr Charlie Outhwaite of UCL,said losing insect populations could be harmful not only to the natural environment,but to human health and food security,particularly with losses of pollinators(传粉昆虫)."Our findings highlight the urgency of actions to preserve natural habitats,slow the expansion of high-intensity agriculture,and cut emissions to reduce climate change," she added.

In the latest study,the researchers pulled together data on the range and number of nearly 20,000 insect species,including bees,ants,butterflies,grasshoppers and dragonflies,at about 6,000 different locations.In areas with high-intensity agriculture and substantial warming,insect numbers have decreased by 49%,compared with relatively untouched places that have so far avoided the most severe impacts of climate change,according to the research published in Nature.

But the researchers said there was some cause for hope.Setting aside areas of land for nature creates a refuge(庇护所) for insects,which need shade to survive in hot weather."Careful management of agricultural areas,such as preserving natural habitats near farmland,may help to ensure that vital insects can still survive," said Dr Tim Newbold,also of UCL.

Study researcher,Peter McCann,added,"We need to acknowledge how important insects are for the environment as a whole,and for human health and well being,in order to address the threats we pose to them before many species are lost forever."
