In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment. Modern businesses have been following his lead,with more tactics（策略）.

One tactic involves where to display the goods. Foe example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food（垃圾食品）later in their trip. In department stores, section is generally next to the women's cosmetics(化妆品) section：while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over cosmetics they might want to try later.

Besides, businesses seek to appeal to customers' senses. Stores notice that the smell of baked goods encourages shopping, they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wine went up.

           When it comes to the selling of houses, businesses also use highly rewarding tactics. They find that customers make decision in the first few second upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the poll through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $10 million houses.

    It encouraged us to visit Quora. com, the online question and answer community, to find out how users get the most out of every tank of gas.

    Light makes right

    Alex Elderfield noted that excess weight prevents an engine from burning fuel efficiently. "Only carry what is essential in your car, clean out any junk or necessary items otherwise you are paying for the fuel to cart these from place to place," he wrote.

    Driving smoothly — that is, not mashing the gas and then slamming the brakes later down the road — was a fixture of many responses. Quora user Clint Law agreed on that advice, who wrote, "Every little bit of kinetic energy that your brakes lose, your engine burned in fuel to build up." Overbraking should consequently be viewed as wasted acceleration. "That's really what kills your fuel economy," he argued.

    Keep the pressure up

    Keeping the recommended tire pressure for your car was another mantra among Quora users. Marlyn Rosent said she checked her tire pressure every time she filled up her SUV. Quora user Doug Dingus checks his tire pressure every weekend. “Less tire contact means reduced rubbing, requiring less fuel,” he said.

    Air conditioning or windows

    Though the summer heat get many drivers to roll up the windows and turn on the air conditioning, some people argued that running the A/C wastes too much gas. In between were many shades of grey.

    Achilleas Vortselas said it would depend largely on a car's speed. He wrote that as a general rule, people should drive with the windows down around the city and turn the air conditioning on when hitting the highway, where a car's aerodynamic(空气动力的) characteristics would be influenced by opened windows.

    More seriously minded people, however, said to travel as much as possible with windows up and the A/C off. Eddie Xue gets by with just a wisp of outside air. “Use the fan and open your windows every now and then at lower speeds," he wrote.

Tickets are $50 and include an autographed (签名的) copy of Known and Unknown.

    Many years later, when people recall the 2018 Russia World Cup, they will remember many things. With the tragic ending of the defending champion Germany, Mexico has triumphantly and suddenly lost three goals in the face of Sweden. But people will never forget the back of a lonely person. That is Lionel Messi.

    31-year-old Messi took off the green armband of his left arm and suddenly fell out. In the recent match, he and his team lost the game against France. The 19-year-old striker Mbappé relentlessly ripped apart the Argentine defense line and scored twice, which made a great contribution to the victory of France.

    On this planet, anyone who knows a little about football knows the name Lionel Messi and his golden years from 2007 to 2017.

    In 2007, 19-year-old Messi tied Real Madrid three times with a hat-trick, and began his legendary career.

    In the past ten years, Mr. Football, the Golden Globe Award and the Golden Boot Award have been taken over by him.

    He led Argentina and Barcelona to make a name for themselves in the world, and has a brilliant record in the Champions League, America's Cup and World Cup.

    Eleven years later, Messi stood on the Kazan Stadium. After four World Cups, he knew that this might be the last time he led Argentina to the World Cup.

    Since 1986, Argentina has never won a championship again. As a captain, he has a great responsibility, even stating that he would withdraw from the national team if he did not win the championship this year.

    This is a prophecy.

    Messi, who eventually failed to save the game, did not receive any interview after standing up on the lawn; leave behind only a legendary image for the world.

    It is Saturday afternoon. You and your friends are planning to go to the movies and then spend the night together. Just as you start to get ready, your dad reminds you it is your aunt's birthday and the whole family is going out to dinner to celebrate. How can this possibly end without a huge argument?

    One of the greatest sources of tension (紧张) between teenagers and their families is the struggle to balance personal desires with family expectations. As you are getting older, you are becoming more independent and more interested in being with your friends. However, at the same time, your family is trying to figure out(弄清楚) how to deal with these changes. While you once spent most of your free time with your family, you are now often absent from home. Parents may get their feelings hurt. Or they might feel that they are losing control of their family during this period. You might feel angry that so many family demands are placed on you.

    There are a few things you can try to make it a little easier to ease the tension.

    Make your plans ahead of time. Ask your parents if there is anything else planned at that time.

    When something with your friends interferes (冲突) with a family event, try to figure out if there is any way you can do both.

    Suggest something you would really like to do with your family. Sometimes parents feel better just knowing their teenager wants to spend time with them.

    Some of the time you won't be happy with the outcome. You might either have to disappoint your parents or have to miss out being with your friends. However, if you show consideration for the feelings of both your family and your friends, you can solve the problem in a tender（和善的）way.

    The vast majority of green sea turtles in the northern Great Barrier Reef are female because of warmer temperatures due to climate change, which influences their sex, researchers said. Scientists are concerned populations of these animals could turn almost completely female.

    A recent study by the National Oceanic and Atmospheric Administration, California State University and Worldwide Fund for Nature Australia examined two genetically distinct populations of green sea turtles living in the Great Barrier Reef. The study found that a group of about 200,000 turtles living in the northern part of the reef was almost entirely female. While the southern population was 65 to 69 percent female, females in the northern group accounted for 99.1 percent of young turtles and 86.8 percent of adults.

    After combining their results with temperature data, the scientists found that most sea turtle populations are living above the most suitable temperature. The northern green turtles have been producing mainly females for more than two decades and that the complete feminization of this population is possible in the near future, making it clear that climate change is threatening the survival of these populations.

    Dermot O'Gorman, the chief executive of World Wildlife Fund Australia, said, “That's a very visible sign of the impact of climate change. But this is a quiet change.”

    O'Gorman said more urgent action on climate change is clearly needed, adding that some conservationists have already taken practical measures, such as using shade cloth on turtle nesting beaches to lower the sand temperature, and reducing by catch in the fishing industry.

    “Shade cloth can be used in certain places, but there's a limit to the scale you can do that,” he said, “Now every large male who can reproduce is going to be even more important.”
