We all have found memories of taking a few lazy months off after the stress of A-levels. As we draw to the end of an academically and socially packed year, the idea of doing the same again is appealing.

    But after graduation, there will be few occasions when we can enjoy such extended holidays, free to do as we wish. So now that summer has arrived, let's take full advantage. It goes without saying that summer vacations are the perfect time to go traveling, especially if you avoid the pricey school holiday period.

    Tickets go up greatly when you turn 26, so make the most of cheaper rates while you're eligible. Finding a reliable company that won't cheat you is extremely important, as is discovering a program that appeals to your own interests. There are plenty of websites where you can see other people's recommendations.

    Of course for most of us, money is tight—but to avoid overspending you can combine employment and adventure. Hannah Warn, a psychology student at the University of Winchester, is spending her summer at Camp America, an increasingly popular venture where British students enjoy a good time on a summer camp.

    “Being thrown into something where I don't really know what to expect is exciting.” she says.“It gives me a chance to experience being away from home in a different way.”

    Those with a talent for languages might also consider working abroad as an au pair. The work may be challenging, but it's a chance to involve yourself in a new culture while your employer pays most of the bill.

    If you have an idea about the sort of career you'd like, getting work experience is wise. In many careers, graduating with only your degree to show for your three or four years just won't make it. Send applications off early and to as many places as possible. Make sure you take a well-earned break this summer.

    Research finds out why some people are constantly under attack from the bloodsucking insects while others walk free.

    For those unfortunate enough to feature highly on the mosquito hit list, summer nights can be synonymous with mosquito bites. Yet others hardly ever get bitten. So how do the bloodthirsty insects select their victims?

    The insects' tastes may seem arbitrary. However, research shows that when mosquitoes make their choices between potential victims, it all comes down to scent (气味).

    “Mosquitoes are attracted by carbon dioxide and heat, which everyone gives off. But mosquitoes are also attracted by certain scents,” says Karl-Martin Vagn Jensen, the head of research at the Department of Agricultural Science at Arhus University.

    According to Jensen, it has not yet been confirmed exactly what the scents in question are. But research does indicate that some scents are more attractive to mosquitoes than others.

    “All the lab employees rubbed petri dishes (培养皿) against their stomachs. In that way, their scents were put on the dishes, which were then put in a container full of mosquitoes,” he says. “The mosquitoes repeatedly landed on some of the petri dishes, but didn't go anywhere near the others.”

    Perhaps taking inspiration from popular fiction, there are also those who consider garlic as an excellent repellent (驱虫剂) against the winged bloodsuckers. According to the researcher, this strategy may not be entirely fruitless. “As far as I know, there is no scientific proof that eating garlic works. But there may be something to the theory that it's possible to mask scent with garlic,” he says. The only reliable method of protection against mosquitoes is to use repellents that are sold over the counter. It contains some smells that can confuse the mosquitoes. When the mosquito comes closer, it uses smell, heat and carbon dioxide to decide whether to bite. But if it is confused by a repellent, it will never get that far.

    In my memory, winters always used to be really unpleasant. You had to bundle up just to keep warm when you went outside. You were often cold, wet, slip on the ice, and you'd arrive home to an ice-cold house. And that would mean turning on the heating and waiting. It's a miracle you didn't get cold to the bone.

    Fortunately, things don't have to be so challenging any more. Technology, engine ring and design have advanced giving us new solutions to old problems. It means dealing with winter needn't be like skating on thin ice.

    With a smart thermostat (温度自动调节器), our homes can be warm when we need them to be. Many models feature smartphone apps that allow you to control temperature remotely, so we can warm up the house before we arrive home. According to techradar.com, Tado's model features voice control, while the Nest 'leans' your habits and automatically heats the home for you.

    Clothes have been given an upgrade, too. Electronic thermal jackets, sweaters and coats heat up when you turn them on. What better way to keep warm in the dead of winter? At the touch of a button, or through an app on our phones, the clothing generates heat from elements placed inside. Many models offer three levels of heating which stay warm for over 12 hours. .

    Finally, there is the clothing for the head, beanie s and Earmuff, that feature speakers included in the fabric using Bluetooth technology so we can listen to our favourite music or, in some cases, have a phone callusing the in-built microphone. All while keeping the head warm and avoiding a cold.

    For many, the thought of winter used to be enough to make their blood run cold. But using technology, life needn't freeze up. With the right solutions, there's no reason why winter can't be really, really cool.

    In the western Los Angeles sits the famous city of Hollywood, known as the global center of movie studios and film stars.

    The Selig Film Manufacturing Company was the first major film company to come to Hollywood, shooting its first film entitled The Heart of A Race Tout in 1908. The next year the film company built the first permanent film studio.

    Although electric lights existed at that time, none were powerful enough to adequately expose film. The best source of illumination for movie production was nature sunlight. Besides the sunny weather, film producers were also drawn to Hollywood because of its open spaces and wide variety of natural scenery.

    Another reason was the distance of Southern California from New Jersey, which made it more difficult for Thomas Edison to enforce his film patents. At that time, Edison owned almost all the patents relevant to film production. As a result, in the East, movie producers acting independently out of Edison's Motion Picture Patents Company were often accused by Edison. But in Los Angeles, things were different. If he sent his men to California, word would usually reach Los Angeles before they did and the movie makers could escape to nearby Mexico.

    In 1911, a second movie studio—Nestor Studios, was founded. At about the same time, many film production companies from New York and New Jersey started moving to sunny California because of the good weather.

    The first Academy Awards presentation ceremony took place in 1929 in the Hollywood Roosevelt Hotel. Tickets were $10 and there were 250 people attending the ceremony.

    From about 1930, five major "Hollywood" movie studios in Hollywood, Paramount, RKO, 20th Century Fox, Metro-Goldwyn-Mayer and Warner Bros, owned almost all large theatres throughout the country for the exhibition of their movies. The period between the years 1927 to 1984 was considered the "Golden Age of Hollywood".
