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.

    In a research carried out in the UK, it was found that only four out of every five employees were happy at work. Surprisingly, it wasn't the pay or the love for the work that made people happy. Instead, friendly, supportive colleagues and a good manager have been found to be the primary causes of happiness at work. So how do you develop a sense of joy on the job? Here are some suggestions.

    Happiness is a state of mind, so staying happy at work is completely based on a positive attitude towards your job. Focus on the bright side of the work rather than keep talking about what makes you unhappy.

    Challenge yourself and take charge of your own growth in your career. Boredom is one of the primary factors that cause people to change jobs. Find new challenges and it's a great feeling to take control over what you do and see a task through.

    Having co­workers you like and enjoy working with is a feature of happiness in the workplace. Talk to people, get to know them and try to get along well with them in the workplace. Meeting new people and getting fresh views can help you to keep yourself interested in your work.

    Complete your tasks, no matter how disagreeable or tough they might be. This gives you a sense of achievement and encourages you to work towards your goals in future.

    Sitting and staring at your screen all day long isn't going to help you. Instead, take breaks and go outside for some time. For example, go out for a few minutes to feel the breeze (微风). Eat your lunch outside or work for a few minutes during that hour, which helps you stay happy at work.

    On February 6, Space X, a private US aerospace company owned by Elon Musk, has successfully launched its new Falcon Heavy spacecraft, making it the world's most powerful rocket.

    Falcon Heavy is the largest rocket since the retirement of NASA's Saturn V, which was used for the Moon missions in the 1970s. “Falcon Heavy can launch about 64 tonnes into low Earth orbit-that's almost three times more than the current running biggest launch vehicle, Delta IV Heavy, ”Imperial College astrophysicist David Clements told AI Jazeera. According to Space X, Falcon Heavy can lift into orbit a mass greater than a 737 jet loaded with passengers, crew, luggage and fuel.

    The rocket was designed with the idea of earning humans into space and opening the possibility of flying missions with people to the Moon and even Mars. For its first voyage, it carried Musk's $ 100,000 cherry-red Tesla sports car and a fake space-suited human model fixed in the driver's seat. Musk joked that “it may be discovered by some future alien race”.

    Falcon Heavy went into space on its last flight on February 6. The launch took place at NASA's Cape Canaveral Air Force Station and Kennedy Space Center in the US state of Florida, the spot also used for the Apollo 11 Moon mission and several space shuttle launches. It was delayed by several hours because of high winds in the upper atmosphere. Minutes after take-off, the two outer boosters (助推器) landed at the nearby Cape Canaveral Air Force Station.

    Space X announced plans to eventually use Falcon Heavy to launch two paying space tourists on a trip around the Moon. However, Musk said he will probably reserve that mission for another launch system, the BFR. Recently, Space X scheduled to launch a Falcon 9 rocket for NASA's TESS mission on March 20, 2018. It is reported that Space X is scheduled to complete 30 independent launch missions in 2018, at least half of which will use Falcon 9.

    In China, Major Cold (大寒) is the last solar term in winter and also the last solar term in the annual lunar(阴历的) calendar. In this period, snow, rain and icy cold weather have a big influence on people's lives.

    Here are several things you should know about Major Cold.

    Eating "dispelling cold cake" (吃"消寒糕")

    During Major Cold, people in Beijing have a habit of eating "dispelling cold cake", a kind of rice cake. Sticky rice, the cake's main ingredient, contains more sugar than rice, which can make people feel warm all over their bodies. In Chinese the word "rice cake" has the same pronunciation with the word "higher in a new year", which symbolizes good luck and continual promotion.

    Eating fried spring roll（吃春卷）

    In Anqing of Anhui province, people traditionally eat fried spring rolls during Major

    Cold. They use a round, cooked, thin pancake to wrap stuffing（馅料）in a thin roll. Then it is fried in a pan with oil until it turns yellow and floats to the top. The stuffing inside the spring roll contains meat or vegetables and the flavor can be salty or sweet.

    Drinking stewed soup

    People in Nanjing of Jiangsu province like to drink stewed soup during Major Cold, which can make people feel warm from head to foot. They always stew the aged hen soup with ginseng(人参), matrimony vine(枸杞) and black fungus(黑木耳).

    Doing winter sports

    There is a saying that goes, "Dripping water freezes during Minor and Major Cold." In various regions of China, Major Cold is the perfect time for winter sports such as skiing, ice skating and sledding.

    Mr. and Mrs. Wormwood had a son called Michael and a daughter called Matilda, who was so quick to learn that her ability should have been obvious even to the most stupid parents. But she was their daughter. To tell the truth, I doubt they had noticed she crawled into the house with a broken leg.

    By the age of one and a half her speech was perfect and she knew as many words as most grown-ups. The parents, instead of praising her, called her a noisy chatterbox and told her sharply that small girls should be seen and not heard.

    By the time she was three, Matilda had taught herself to read by studying newspapers and magazines that lay around the house. At the age of four, she could read fast and well and she naturally began seeking for books. The only book in the whole of this enlightened household was something called Easy Cooking belonging to her mother, and when she had read this from cover to cover, and had learnt all the recipes by heart, she decided she wanted something more interesting.

    "Daddy," she said, "do you think you could buy me a book?

    "A book?" he said. "What do you want a book for?"

    "To read, Daddy."

    "What's wrong with the telly? We've got a lovely telly with a twelve-inch screen and now you come asking for a book!"

    Nearly every weekday afternoon Matilda was left alone in the house. Her brother went to school. Her father went to work and her mother went out playing bingo. On the afternoon of the day when her father had refused to buy her a book, Matilda set out all by herself to walk to the public library in the village. She asked Mrs. Phelps, the librarian, if she might sit a while and read a book. Mrs. Phelps, slightly surprised at the arrival of such a tiny girl unaccompanied by a parent, nevertheless told her she was very welcome.

    "Where are the children's books please!" Matilda asked.

    "They're over there on those lower shelves," Mrs. Phelps told her. "Would you like me to help you find a nice one with lots of pictures in it?

    "No, thank you." Matilda said. "I'm sure I can manage."

    From then on, every afternoon, as soon as her mother had left for bingo, Matilda would walk down to the library, where she spent two glorious hours sitting quietly by herself in a cosy comer devouring one book after another. When she had read every single children's book in the place, she started wandering around in search of something else.

    Mrs. Phelps, who had been watching her with interest for the past few weeks, now got up from her desk and went over to her. "Can I help you, Matilda?" she asked.

    "I'm wondering what to read next," Matilda said. "I've finished all the children's books."

    "You mean you've looked at the pictures?"

    "yes, but I've read the books as well. I thought some were very poor, but others were lovely. I like The Secret Garden best of all. It was full of mystery. The mystery of the room behind the closed door and the mystery of the garden behind the big wall".

    Mrs. Phelps was stunned." Exactly how old are you, Matilda?" she asked.

"Four years and three months," Matilda said." I would like a really good book that grown-ups read .A famous one."

    Mrs. Phelps looked along the shelves, taking her time." Try this", she said at last," It's very famous and very good. If it's too long for you, just let me know".

    "Great Expectations," Matilda read, "by Charles Dickens. I'd love to try it"

    On her first day in New York City, teaching students from low-income families at an after-school program, Alyssa Kapasi noticed so many kids were lining up for free sandwiches and fruit in the cafeteria. Many of these poor students don't get enough food to eat at home, so a free school lunch or a free after-school meal might be the most food they would get all day.

    Kapasi, who graduated from private school, was shocked. Therefore, she was determined to help. “I want other kids to understand that if they meet a problem, they don't have to wait to be an adult to salve it,” says Kapasi. She and a group of friends are now putting their programming skills ta work to create an app called Food for Thought, which will allow parents, students and even kind-hearted strangers to donate to a lunch account for a student in need at a nearby school.

    About 20 million American kids receive free lunches. Two million more quality for reduced-price meals, and those students' families may pay for part of their food. When they don't have the money on any day, the students might have to choose an “alternative meal” such as a free cheese sandwich.

    One clever feature of the app which is being supported by donation from companies and social investors—is that it provides anonymity (匿名) to lunch recipients and donors. To receive financial help, a family will need only a recommendation from a school administrator, and no one else knows.

    “I want to make the application a platform where all users feel no shame in using it,” says Kapasi. She hopes to test the app in a school district next month. And then, she will devote herself to charity.
