Exploit your parking space

    An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement for free on Letpark or At my house park.

Rent a room

    Spare room? Not only will a lodger（房客）earn you an income, but also, thanks to the government-backed “rent a room” program, you won't have to pay any tax on the first £4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.

    Make money during special events

    Don't want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money. Grashpadder can advertise your space.

Live on set

    Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free—but you will be charged if your home gets picked.

Use your roof

    You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment (around £14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof.

    An old friend from California called from the airport to tell me that he had arrived. I was not able to leave the office, but I had made plans for his arrival. After explaining (解释) where my new house was, I told him that I had left the key under the doormat (门垫). Since I knew it would be pretty late before I could get home, I suggested that he make himself at home and help himself to anything that was in the refrigerator(电冰箱).

    Two hours later my friend phoned me from the house. At the moment, he said, he was listening to some of my records after having had a delicious meal. Now, he said, he was drinking a glass of orange juice. When I asked him if he had had any difficulty finding the house, he answered that the only problem was that he had not been able to find the key under the doormat, but luckily, the living room window by the apple tree had been left open and he had climbed in through the window. I listened to all this in great surprise. There is no apple tree outside my window, but there is one by the living room window of my next door neighbor's house!

    The yearly Academy Awards ceremony was once a private affair. Now, because of television, it is very much a public affair. Hundreds of people gather in Hoolywood to see the Oscars presented to outstanding actors, and others involved（参与） in the motion picture industry. Millions more watch on the television.

    It all began on May 16, 1929, when 270 men and women sat down to dinner at the Hollywood Roosevelt Hotel. There was no secret about the winners. The names of the winners had been known for months. Janet Gaynor, for example had won as Best Actress. Douglas Fairbanks presented her with the famous gold statue（塑像）. The little statue was not then called Oscar. Like a new actor, Oscar was unknown. About six years later, it somehow got that renowned name. A number of explanations have been offered for its origin(由来), but nobody knows the true story for certain.

    Nowadays the result of the Oscar voting are kept secret. Only two people know the winners before the names are announced at the ceremony. The counting of votes is not done by one group of people but by different groups. Nobody except two members of an accounting company sees the final results.

    The information is not kept in open files. Winners' names are placed in closed envelopes. The accountants each carry a complete set of envelopes to the ceremony. One set is simply a spare to be used in case something happens to the other one.

    Getting stuck in a traffic jam is one of the most boring problems for people living in big cities. The fact that you're moving so slowly leads too stress, anger and the wish that your car could just fly over the traffic like an airplane.

    Soon, however, that wish could come true .On May 8, US car-renting company Uber showed off what it described as "the transportation mode of the future: on-demand air transport," reported ABC News.

    According to Nikhill Goel, head of products for Uber Air, the company's air taxi service may launch test flights in the US cities of Dallas and Los Angeles, as well as Dubai in the United Arab Emirates, as early as 2020. If everything goes according to plan, passengers will be able to fly to work by 2023.

    When the Olympics comes to Los Angeles in 2028. Uber "expects to have hundreds, if not thousands, of its aircraft in the skies." Goel told Newsweek.

    So what would Uber's flying vehicles be like?

    They are small, electric aircraft that take off and land vertically (垂直地) , and they give off zero emissions (排放) and are quiet enough to operate in cities .

    Just like an airplane, the vehicles will have fixed wings to help them glide. But while a helicopter has just one big fixed rotor (定量). Uber's vehicles will have multiple rotors , which will help increase fuel efficiency (效率) while reducing emissions and noise.

    Because of these fixed wines and multiple rotors. Uber's flying taxis "should be quieter and safer than a helicopter." reported ABC News.

    However, the service still has a long way to go before it's ready to accept passengers. For example, to avoid any potential accidents. Uber is working with NASA to study air traffic control problems associated with low-flying aircraft. But just as Dubai's Mayor Betty Price said in a news release. "This program is revolutionary and future -oriented (面向未来的)."

    The school year has barely started in Denver, and French teacher Tiffany Choi is already worried that her students are suffering from absent-mindedness. The problem isn't texting, playing video games or passing notes. It's Denver's ongoing heat wave.

    "Today was a little bit hot, so I noticed kids were very sleepy and they were having to get up to drink water quite often." said Choi, who works at Denver's East High School. "If you lose too much water, and you have to keep going to the water fountain, that can take away from their classroom experience." While nodding off in class on a warm day may seem like a right of passage for the average teen, Choi's observation carries a bigger consequence than parched (干燥的) lips.

    "There's been quite a few media reports about teachers noticing that students weren't able to focus on hotter days," said R Jisung Park, a researcher, "Does a hotter climate during the school year actually affect the rate of learning?" The drops in academic achievement couldn't be explained by hotter weekends or hotter summers, but the trend was connected to higher temperatures on school days alone.

    The connection between lost learning and a greater number of hot days is one more example of how climate change is already affecting our lives-and it's an alarm bell for what we stand to lose in the future. Humans still have time to lessen the worst consequences of continued global warming. But unless significant changes occur in the next decade-which seem more and more unlikely—the world will be locked into an inescapable period of heat waves unlike our species has ever seen.
