(Q = Question; A = Answer)

    Situation I

    Q: If someone sits right next to me in an empty movie theater, is it rude to move?

    A: Maybe, but nobody will fault you for it. Chances are that close sitter doesn't realize he disturbs you, so he may miss your annoyance. You undoubtedly aren't the first person he's met who needs enough room. Forgive his bad judgment, move quietly and enjoy the show.

    Situation II

    Q: If I use the bathroom at a store, do I need to buy something?

    A: Consider frequency and urgency. Is this a one-time or an emergency? If so, you don't have to buy anything, but it would be kind if you did. However, if you regularly use the bathroom at this place, then you are a customer, and you should act like one.

    Situation III

    Q: If someone is talking loudly on the bus, is there a nice way to ask him to keep it down?

    A: No. Try other means.1) Stare at him until he gets aware of it and quiets down. 2) Lift your finger in a silence motion(动作)and smile. 3) Put on earphones and ignore him.

    Situation IV

    Q: If I remember my friend's birthday a day late, should I apologize or just wish her a happy birthday like nothing happened?

    A: This is the reason why the word belated was invented. "Happy belated birthday!" is short for: "Well, I know I forgot, but then I remembered. Forgive me and happy birthday."

    Situation V

    Q: Can I lie about seeing a text because I was too busy or lazy to respond(回复) to it?

    A: Don't lie. Receiving a text does not mean you need to respond to it. Why waste a perfectly good lie when the truth will serve? "Yes," you can say if ever asked, "I saw it." No explanation is needed as to why you don't respond.

    Rapid advances in a new technology will soon transform science fiction into reality — meaning people will have driverless cars, small robots at their command and the ability to experience being in another place without leaving home, predicted Google executive chairman Eric Schmidt at the Mobile World Congress in Barcelona, the planet's largest cell phone trade show.

    Introduction of books available online, Internet translation of languages and voice recognition for computers all happened much faster than anyone could foresee and that technological research into even more previously unheard of advances is progressing at a fast speed.

    “People who predict that holograms（全息图）and self-driving cars will become reality soon are absolutely right,” Schmidt told thousands of attendees. Research under way will lead to situations where people can put themselves at events like a rock concert so that they can see, hear and even feel the event. And turn down the volume, if it's too loud.

    One attendee said she was scared that the possibility could be dehumanizing, but Schmidt replied by holding up his cell phone into the air. “It has an off button and it is here on the right,” Schmidt said. “My point is that it is all about your control. If you don't like my version of a rock concert, I'm not forcing you to go.” In the future, small robots could be used so busy people can send them to events for video and voice transmissions when their presence isn't required, Schmidt said.

    Technology in the near future will redefine the relationship among people in the world. “With technology comes power and with power comes choice, and smarter resourceful citizens are going to demand a better deal for their new life,” Schmidt said.

    Color is fundamental in home design-something you'll always have in every room. A grasp of how to manage color in your spaces is one of the first steps to creating rooms you'll love to live in. Do you want a room that's full of life? Or are you just looking for a place to relax after a long day?{#blank#}1{#/blank#}, color is the key to making a room feel the way you want it to feel.

    Over the years, there have been a number of different techniques to help designers approach this important point.{#blank#}2{#/blank#}, they can get a little complex. But good news is that there're really only three kinds of decisions you need to make about color in your home: the small ones, the medium ones, and the large ones.

    {#blank#}3{#/blank#}.They're the little spots of color like throw pillows, mirrors and baskets that most of us use to add visual interest to our rooms. Less tiring than painting your walls and less expensive than buying a colorful sofa, small color choices bring with them the significant benefit of being easily changeable.

    Medium color choices are generally furniture pieces such as sofas, dinner tables or bookshelves.{#blank#}4{#/blank#}.They require a bigger commitment than smaller ones, and they have a more powerful effect on the feeling of a space.

    10-year-old Mikaila Ulmer from Texas is building a lemonade（柠檬水）empire, hoping to save honey bees in the process.

    It all started when Mikaila was 4 years old and she was bitten by a bee twice in one week. This caused her to become very scared whenever bees were near. In order to help her manage this new fear, Mikaila's parents asked her to do some research on bees. She learned that bees are quite important for flowers, gardens and trees. She also learned that they are dying at a rapid rate. In the past year, honeybee farmers have reported losing nearly 42% of them. Many believe that this could be due to the overuse of pesticides（杀虫剂）.

    This is when she set her mind to create a product to help save bees. She started her company BeeSweet Lemonade. Her special lemonade recipe came from her great-grandmother's cookbook. She adds honey to it, instead of sugar. In order to call attention to the problems honeybees face, Mikaila sells lemonade almost every day at her lemonade stand. And she takes every opportunity to tell her customers about the problems that face honeybees.

    What began as a small activity is starting to grow. BeeSweet is projected to sell almost 140,000 bottles of lemonade this year. BeeSweet lemonade can be found on the shelves at select Whole Foods Markets as well as many restaurants and other locations near her home.

    Does Mikaila have any time to just be a kid? Sure! Every weekend Mikaila does something fun. She doesn't mind the hard work though. She says that she is happy watching people enjoy her lemonade. The more people enjoy it, the more they're learning about the bees.

    A population of the world's most aggressive mosquito species was almost completely wiped out by an experiment on two islands in the southern Chinese province of Guangdong, according to a study published.

    The experiment successfully reduced the female Asian Tiger Mosquito population — the main source of bites and disease spread — by up to 94%, reducing the number of reported human bites by 97%.

    One of the Chinese study's researchers, Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study. Running a mosquito factory in southern China, he previously attempted to use sterilized male mosquitoes to mate with unaltered females which developed normally. In the new study, published by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even further by limiting both males and females' ability to reproduce. The results were so successful that they nearly killed the entire female mosquito population on the two islands.

    It isn't the first attempt by researchers to reduce mosquito populations across the world. In 2018, scientists from the Imperial College of London used gene-editing tools to make female mosquitoes sterile, while males developed normally and continued spreading the genetic mutation (突变).Experts said the Asian Tiger Mosquitoes are particularly hard to kill using traditional population control methods, such as pesticides (杀虫剂) and removing stagnant (不流动的) water where the insects lay their eggs.

    Mosquitoes create grave threats to human health beyond just bites. The World Health Organization (WHO) has described the insects as "one of the deadliest animals in the world," due to their ability to rapidly spread deadly diseases such as dengue fever and malaria. There is currently no effective vaccine or treatment for most mosquito-spread diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science. “A new tool like what's being described in this paper is very much needed” said Stephen Dobson, a professor of medical insectology at University of Kentucky.
