What makes a person a giver or a taker? The idea of “give versus take” takes shape in all relationships of our lives. We're either giving advice, making time for people, or we're on the receiving end. We alternate between the two based on different situations we face on a daily basis, it not an hourly one.

    According to Adam Grant, a professor at Pennsylvania University, most people are matchers. They make careful observations on takers and make it a point for them to pay something back. They hate to see people who act so generously towards others without receiving any reward. Actually, most matchers will try to promote and support givers so that they can get the good they deserve.

    Another professor named Hannah Rile Bowles, from Harvard University, led a study on the idea. She asked 200 senior managers to sit down in pairs where one person would act as the boss and the other as an employee to negotiate salary promotions. Male employees asked for an average salary of $146 k while the females asked for only $141 k. But why did they not bargain as hard as the men? Simply because they were more likely to be givers.

    As a woman, I do enjoy the act of giving up my time, my knowledge and my care and attention to others. I don't expect anything in return, but I do tend to pull myself away when I feel like I'm being taken for granted. I also tend to get upset when I see a loved one's continuous actions of kindness go unnoticed. So it's safe to say I'm 50% giver,35% matcher and 15% taker.

    I do know someone, however, who is 99% giver. They're devoting their time, sharing valuable insights and going out of their way for everyone who crosses their path. Although they've changed the lives of many people, they rarely see any of it returned. But the universe is slowly repaying them; they're now extremely successful, well known for what they do.

    One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem—inability to read.

    In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

    There on the book's cover was a beagle which looked identical (相同的) to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

    Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. The dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

    My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

    I never told my mother about my “miraculous” (奇迹般的) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words was held.

    In some northern places, the cost of heating our homes boosts. Now millions of people are saving on their heating bills with the EP heater(加热器). With over one million satisfied customers around the world , the new EP heaters saves more heating bills, and runs almost silent.

    The EP has no exposed(暴露的) heating parts that may cause a fire. The outside of the EP only gets warm at the flick of a switch so that it will not burn children or pets.

    The EP will not reduce oxygen(氧气) in the room. With other heaters, you'll notice that you get sleepy when the heat comes on because they are burning up oxygen.

    The advanced EP also heats the room evenly, wall to wall and floor to ceiling(天花板). It comfortably covers an area up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. And they only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.

    The EP comes with a 3-year warranty(保修) and a 60-day, no questions asked, satisfaction guarantee. If you are not totally satisfied, return it at our expense and your money will be given back to you.

    Now we have a special offer for 10 days, during which you can enjoy a half price discount and a free delivery. If you order after that, we reserve the right to either accept or reject order requests the discounted price.

The hottest cities in the world

    The locations below are the hottest and also travel destinations on the planet.

    Bangkok

    According to the data, Bangkok is the hottest city on the planet﹣not because of any particularly impressive high temperatures, but because it is consistently hot all the year round. The city has an average annual temperature of 29℃, coupled with high dampness and an average of 128rainy days per year; while the highest temperature on record is 40℃.

    Timbuktu, Mali

    Located on the southern edge of the Sahara Desert, the African city of Timbuktu is similar to everything remote. It's also one of the hottest cities in the world, with a hot, dry climate offering record highs of 49℃. Throughout April, May and June, average maximum temperatures are beyond 40℃. Modern﹣day Timbuktu is slowly being swallowed by the desert and is certainly a shadow of the trade center that it once was.

    Ahvaz, Iran

    Built on the bank of the Karun River, Ahvaz is an industrial city with average highs of around 46℃ during July, its warmest month. The city's record high is 54℃, making it one of the world's hottest cities during the summer. Frequent sand and dust storms and an absence of rain from July to September mix with its sky﹣high temperatures.

    Kuwait City

    The wealthy capital of Kuwait is another competitor for the title of the world's hottest summertime city with average highs of over 45℃ from June to August. Nightfall brings little respite（缓解）, with after﹣dark low temperatures often over 30℃ during the summer months. Kuwait City's record high is 52℃, while it rains on an average of just 19 days per year.

    If you think American cooking means opening a package and throwing the contents into the microwave oven (微波炉), think again. On the one hand, it's true that many Americans have cold cereal for breakfast, sandwiches for lunch and instant (方便的) dinners. From busy homemakers to working people, many Americans enjoy the convenience of fast food that can be ready to serve in 10 minutes or less. On the other hand, many Americans realize the importance of cooking skills. Parents—especially mothers'—see the importance of training their children—especially daughter's. Most Americans think that there's nothing better than a good home-cooked meal. But with cooking, as with any other skill, good results don't happen by accident.

    Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal, they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.

    For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.

As part of our mission to inspire the next generation of scientists, inventors and engineers, the Science Museum Group (SMG) has launched an exciting new online game—Total Darkness.

Over the last year we have been developing Total Darkness with the aim of creating an experience that can have a positive impact on people's attitudes towards STEM (science, technology, engineering and maths), as well as having a focus on self-reflection, rather than asking players to recall specific facts or concepts.

Total Darkness is a digital storytelling experience which encourages young people to recognise how the skills they use every day relate to STEM and can help them develop their confidence in science thinking. The game invites the player to solve a mysterious power cut in their hometown. The game puts players in control, allowing their choices and decisions to guide them through the story.

As the player navigates through the darkened streets of the town, equipped only with a torch, they will face various challenges. Using their curiosity, communication skills and creative problem solving, they will discover new theories about what might have caused the blackout(停电；断电). But with every step their torch fades, and the player must solve the mystery before the battery runs out.

The player's choices and actions throughout the game will score them curiosity, creativity or communication points. At the end, the skills the player has used will be revealed along with their science style, showing how they could put their skills into action in the real world.

Total Darkness is aimed at 8-15 year-olds—an important stage in teens' science development. Research shows that as teens make the step between primary and secondary, many move away from an interest in science as other influences have a stronger pull in their lives.

Total Darkness is a free online game playable on smartphone, tablet and desktop. Play now at totaldarkness.sciencemuseum.org.uk.
