Have your parents ever inspected your room to see if you cleaned it properly? Imagine having your entire houses, garage, and yard inspected at any time -- with no warning. Inspections were a regular part of lighthouse (灯塔) living, and a keeper's reputation depended on results. A few times each year, an inspector arrived to look over the entire light station.  The inspections were supposed to be a surprise, but keeper sometimes had advance notice.
           Once lighthouses had telephones, keepers would call each other to warn that the inspector was approaching. After boats began flying special flags nothing the inspector aboard, the keeper's family made it a game to see who could notice the boat first. As soon as someone spotted the boat, everyone would do last-minute tidying and change into fancy clothes. The keeper then scurried to put on his dress uniform and cap. Children of keepers remember inspectors wearing white gloves to run their fingers over door frames and  windowsills looking for dust.
           Despite the serious nature of inspections, they resulted in some funny moments. Betty Byrnes remembered when her mother did not have
 time to wash all the dishes before an inspection. At the time, people did not have dishwashers in their homes. In an effort to clean up quickly, Mrs. Byrnes tossed all the dishes into a big bread pan, covered them with a cloth and stuck them in the oven. If the inspector opened the oven door, it would look like bread was baking. he never did.
          One day, Glenn Furst's mother put oil on the kitchen floor just before the inspector entered their house. Like floor wax, the oil made the
 floors shiny and helped protect the wood. This time, though, she used a little too much oil. When the inspector extended his hand to
greet Glenn's mother, he slipped on the freshly oiled surface. "He came across that floor waving his arms like a young bird attempting
its first flight," Glenn late wrote. After he steadied himself, he shook Glenn's mother's hand, and the inspection continued as though
 nothing had happened.

    Alaska's state fair, which runs until September 5^th, began as a celebration among residents of the Mantanuska Colony, a project under which 200 farm families were moved to Alaska to see whether agriculture could be possible in the coldest state. The state fair lives on, but little more than a decade after the start of the project most of the participants had abandoned their farms. The project was widely seen as a flop.

    In this state, glaciers cover 300 times more acres than farms. Only 5% of the food consumed is grown locally, compared with 81% nationwide. The growing season is short and summer temperatures chilly. Tomato plants wither(凋谢). Fruit trees, in most parts of the state, are just a dream.

    Enter the high tunnel: a greenhouse consisting of a metal frame with plastic stretched across it. Its few millimeters of plastic separate crops inside from the great outdoors. But this is enough for Alaskan growers to produce tomatoes as well as sweetcorn, peaches and kiwi fruit, and to boost production of crops by a quarter or more.

    In a place where no one blinks(眨眼) if you call yourself a fisherman, boat captain or gold miner, an increasing number of Alaskans are thinking of themselves as people who grow food. Since the start of the programme, the number of farms registered(登记)with the state has nearly doubled. Local restaurants have begun shaping their menus around what neighboring farms can grow.

    Eight decades ago, the Mantanuska Colony tried to turn farmers into Alaskans. Today, the high tunnels are turning Alaskans into farmers.

    Tencent announced yesterday that it will limit the daily time for youngsters to play its popular King of Glory game after parents and schools in Shanghai and other areas complained their children had become addicted to playing it.

    From tomorrow, children younger than 12 will only be allowed to play the game for a maximum(最大值) of one hour a day, and after 9 pm, they will be banned from logging into it, said Tencent. Those older than 12 will be able to play a maximum two hours a day.

    The game system will remind players the time they have been playing and young players will be forced to log out when the time is up.

    Tencent claimed these were the strictest measures in China's game industry to prevent addiction and the company expected they would ease parents' anxiety.

    The company also said it had updated its system for parents to keep tabs on their children using its games.

    Since February, parents can receive messages when children log in and spend money on the game after they connect children's game accounts with their mobile phone numbers.

    Now, parents can connect phones, tablets or computers that their children use to play games, so that they can keep an eye on the children even if they have several game accounts, Tencent said.

    Song Zhe, a father of a Shanghai high school student, welcomed the measures but was not sure if they would be sufficiently effective. "I like the system that could lock up the devices as children can register many accounts," he said, "but children are so clever that they can always think out counter measures."

    Mr. Brown was a writer. He wrote many books, and he thought they were quite good. He lived in the city. One morning, he went to a small town near the city to visit a friend. He went there by bus. When he got to the town, he saw a bookshop not far from the bus stop. As it was early, he decided to go in and have a look. There were many books in the shop. He was very happy that all the books in the shop were written by him. "Where are other writer's books?" he asked the man in the shop. The man looked up at him and answered. "Oh, they are all sold out."

When looking at fashion shows or the latest magazine trends, you might think you've seen it all before. It seems that designers often revisit past concepts （概念）. However, to glimpse the future of fashion, one must turn to the meeting point of fashion and technology, where innovative ideas are born.

For several years now, people have been talking about "wearable technology" as the next big development. You can already buy watches that do everything your smartphone can do, or glasses with computers that follow your eye movements and feed information to you as you walk around. But there's much more to wearable technology than that.

Sports clothing is one of the areas. Runners already wear small computers on their wrists（手腕） that give them continuous information about how fast they're running, how hard their bodies are working, and so on. Experts agree that it's often sportspeople （usually young men） who are the first to take up new fashion ideas. Others then follow.

Women, it seems, are usually more interested in what clothes look like than what they can do, and technology has a part to play here too. Designers are making clothes that can change color with how you feel, or react to sound. And if you think that sounds unlikely, just think of all the things we accept as quite normal today that seemed impossible or silly only ten years ago.

The primary reason such items aren't available in mainstream stores is their high cost. However, like all technological products, their prices are likely to decrease rapidly, as technological clothing doesn't necessarily have to be costly.
