Both of my parents worked full-time when I was a little girl, so my grandmother would stay at our house during the day. We would watch game shows in the living room. Our favorite was The Price is Right. We would call out our answers along with the contestants.

    When I got older and started going to school, we couldn't watch our game shows regularly. That was okay with me, though, because the one thing I liked better than watching game shows with my grandmother was helping her bake. Watching her in the kitchen was amazing: she never seemed to need the recipes but everything she made tasted delicious.

    At first I would just sit in the kitchen and watch, even though I didn't understand what she was doing. As I got older, she let me help with the easy parts, such as measuring the sugar. The day she let me separate the eggs，I felt like I had found complete pleasure.

    At last, my parents decided that I could take care of myself，and my grandmother stopped coming over every day. The love of baking, however, stayed with me. I started baking by myself, and even if the cookies ended up burnt sometimes, more often they turned out pretty well. I tried out new recipes, and whenever I got to a thorny part, I would call my grandmother for advice. Sometimes I would call her just to talk, too. I felt like I could talk to her about anything.

    My grandmother passed away ten years ago, but I still think of her every day. Last week, I found a recipe book she made for me. It included her recipes for brownies, cookies, and my favorite, lemon pie. As I looked through the pages, I thought I could hear her voice. She was the one who taught me not just about baking, but about life.

    Years ago I moved to Woodland Hills to take a job in a small hospital's emergency department. No one wanted to work on Christmas Eve, so the shift（轮班）went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.

    At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.

    The following year I got Christmas Eve duty again. At 9 pm sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr. Lee and said, “You probably don't remember me, but last Christmas Eve you saved my life. Thank you for the year you gave me.” He and his wife hugged me, handed me a small gift, and left.

    The following year a new doctor had joined the group, but I wanted to see if Mr. and Mrs. Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild. Mr. Lee, his family and I spent 13 Christmas Eves together.

    The last year I saw him, he brought me a gift. I carefully opened the package and found a crystal bell inside. It was carved with a single word: Friendship. Now, my family, friends and I ring that bell every Christmas Eve at exactly 9 pm and offer our best wishes to the man who we won't forget.

    You're in a department store and you see a couple of attractive young women looking at a sweater．You listen to their conversation：

    “I can't believe it－Lorenzo Bertolla! They are almost impossible to find．Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome．”

    They leave and you go over to see this incredible sweater．It's nice and the price is right．You've never heard of Lorenzo Bertolla, but those girls looked really stylish．They must know．So, you buy it．You never realize that those young women are employees of an advertising agency．They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes．

    Every day we notice what people are wearing, driving and eating．If the person looks cool, the product seems cool, too．This is the secret of undercover marketing．Companies from Ford to Nike are starting to use it．

    Undercover marketing is important because it reaches people that don't pay attention to traditional advertising．This is particularly true of the MTV generation－consumers between the age of 18 and （3）It's a golden group．They have a lot of money to spend, but they don't trust ads．

    So advertising agencies hire young actors to “perform” in bars and other places where young adults go．Some people might call this practice misleading, but marketing executive Jonathan Ressler calls it creative．“Look at traditional advertising．Its effectiveness is decreasing．”It is true, because everyone knows an ad is trying to persuade you to buy something．However, you don't know when a conversation you overhear is just a performance．

    In general, people talk about two groups of colors: warm colors and cool colors. Researchers in psychology think that there are also two groups of people: people who prefer warm colors and people who prefer cool colors.

    The warm colors are red, orange and yellow. Where there are warm colors and a lot of light, people usually want to be active. People think that red, for example, is exciting. Sociable people, those who like to be with others, like red. The cool colors are green, blue and violet. These colors, unlike warm colors, are relaxing. Where there are cool colors, people are usually quiet. People who like to spend time alone often prefer blue.

    Red may be exciting, but one researcher says that time seems to pass more slowly in a room with warm colors than in a room with cool colors. He suggests that a warm color, such as red or orange is a good color for a living room or restaurant. People who are talking or eating do not want time to pass quickly. Cool colors are better for offices or factories if the people who are working there want time to pass quickly.

    Researchers do not know why people think some colors are warm and other colors are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue, and violet are cool. Perhaps warm colors remind people of warm days and the cool colors remind them of cool days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.

    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.

    Angel Garcia Crespo is a computer engineer at Carlos III University of Madrid in Spain. His group has invented a new way for deaf-blind people to “watch” TV. The idea for the technology grew out of previous work by his group. The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities. But the group wanted to help people with both challenges. So they asked some deaf-blind people what would help.

    In addition to relying on their sense of touch to communicate, deaf-blind people can also get and send information with a Braille line. The Braille system uses patterns of raised dots to stand for letters and numbers. A Braille line is an electronic machine with a changeable Braille display. Dots rise up or drop down based on the information sent to the machine.

    Now the new system changes TV signals to data a Braille line can use. “The key to the system is the possibility of using subtitles(字幕) to collect TV information, " Garcia Crespo explains. "Subtitles travel with the image(影像) and the audio in electromagnetic waves we don't see. But an electronic system can keep those waves."

    First, a computer program, or app, pulls out the subtitles and visual descriptions from the broadcast signal. The system then combines the information and changes both into data for Braille.

    Now another app gets to work, which sends the data out to people's Braille lines on demand. “This is done in real time, in less than a second, " Garcia Crespo says. This lets a deaf-blind person "watch" TV as it's broadcast. The system will work with various Braille lines, as long as there's a bluetooth connection available. Now, the system is only used in Europe, and it should soon be available in the US.
