The Come-back Coffeehouse   The sign in the window read "Carl's Coffee Shoppe," spelled the old-fashioned way. Hallie shook her head and wondered how many times she had suggested an alternative. She entered the shop and saw only one person.

    "I could help with the books, Dad", Hallie offered,"There's not much you could do." Her father signed. "How about if you clean the counters instead?" His statement made her feel like a little girl instead of a senior in high school. Hallie sprayed some cleanser and ran a cloth over the worn counter tops . After she had washed a few of the old eggshell-colored cups, she began her homework. At closing time, Hallie's parents sat beside her. "You know the shop has not been profitable lately," Mr. Rhodes began. "We need to decide if it is even worth keeping it open." "We're going to visit Uncle Harold over spring vacation." Mrs. Rhodes continued. "He can look over the books and tell us what our options are. You and AuntTess will run the shop for the week."

    By spring vacation Hallie was ready for an adventure. Hllie's parents gave some instructions, and said good-bye. Hallie stared absently out the window at the passersby: young people on their way to work, and kids on their school vacation. They were not the same people that her grandpa Carl had served. Suddenly Hallie had an idea. She confided in Aunt Tess, who approved. The two eagerly set to work.

At the end of the week, Hallie was coming out from the kitchen when she saw her parents standing in the shop, confused. She smiled asher parents stared at the teens around the counter and the young families seated at the tables.

    "Welcome back!" Hallie swept her arms to present there staurant's cheerful new decoration. Bright, attractive coverings spread over the tables, and modern posters hung on the walls, while, colorful mismatched dishes contributed to the pleasant atmosphere."

    "I brought board games from home," Hallie added excitedly, "and the bookstore down the street donated the posters. When we talked to our friends about what we were doing, they were happy to give us some dishes." Hallie held her breath as she waited for her parents' reaction.

    "Everyone certainly seems to like the changes," noted Mrs. Rhodes.

    "Speaking of changes," Mr. Rhodes said,"I see our name has changed, too."

    "Do you mind? I changed our name to 'Come-Back Coffeehouse'to make the shop sound welcoming, as in 'Please come back again'..."

    A smile spread across her father's face. "The newname is fitting. Thanks to you, this place certainly has made a come back!"

    Bursting into the classroom from recess, 15 children take their seats and face the woman they know as Ms. Yang.

    “What day is it today?” she asks, in Mandarin Chinese.

    “Confucius' birthday!” the fifth graders shout in Mandarin.

    “Why do we celebrate Confucius' birthday?”

    “Because he's the greatest teacher in the history of China!” exclaims a brown-haired girl. She is speaking Mandarin.

    English is rarely heard in Lisa Yang's class at the Chinese American International School(CAIS), despite the fact that few students are native speakers of Mandarin.

    The United States is actively trying to increase the group of students in “critical languages” such as Mandarin. The students at CAIS are way ahead in such a trend.

    Founded 25 years ago, this small private school in San Francisco, USA, does what few other American schools do: It produces fully fluent speakers of Mandarin Chinese, by far the most commonly spoken language in the world.

    Mandarin Chinese is suddenly hot in American schools. As China becomes the world's leading economy sometimes this century, schools in the U. S. are scrambling to add Mandarin to their list of foreign languages or expand Chinese programs already in place.

    “It really is almost unprecedented. People are looking at China as a force to be reckoned with… And to ensure that the U. S. has the ability to conduct trade, and to work with the Chinese. Certainly having an understanding of Chinese language and culture is an advantage,” said Marty Abbott of the American Council on the Teaching of Foreign Languages(ACTFL).

    To develop Chinese-language programs has not been smooth. A shortage of trained teachers has made it difficult for some schools to join the race. When schools do get teachers, they often hire them straight from China, and the teachers usually suffer culture shock when they come to the U. S.

    Robert Liu remembers his first two years in an American classroom It was not an easy adjustment. “In China, students respect their teachers,” he said. Liu found that American students, however, expect an active teaching style. He had to use games to engage them rather than lectures.

    To avoid many of the problems with foreign teaching styles, the CAIS has been working with the Chinese government to improve training of teachers who are sent to the U. S.

    A young and successful manager was traveling down a neighborhood street, going a bit too fast in his new Jaguar.

    As his car passed a park, one child appeared, and a brick smashed into the Jaguar's side door. He stopped the car very suddenly and drove the Jag back to the spot from where the brick had been thrown. He jumped out of the car, grabbed some kid and pushed him up against a parked car, shouting, "What was that all about and who are you? Just what on earth are you doing? That's a new car and that brick you threw is going to cost a lot of money. Why did you do it?"

    "Please, sir, please, I'm sorry. I didn't know what else to do!" begged the youngster. "It's my brother," he said. "He fell out of his wheelchair and I can't lift him up."

    Sobbing, the boy asked the executive, "Would you please help me get him back into his wheelchair? He's hurt and he's too heavy for me."

    Moved beyond words, the driver tried to swallow the rapidly swelling lump(隆起的肿块)in his throat．He lifted the young mail back into the wheelchair and took out his handkerchief and wiped the scrapes(擦痕)and cuts, checking to see if everything was going to be okay.

    "Thank you, sir. And God bless you, "the grateful child said to him. The man then watched the little boy push his brother to the sidewalk toward their home.

    It was a long walk back to his Jaguar... a long, slow walk. He never did repair the side door. He kept the dent(凹痕) to remind him not to go through life so fast that someone has to throw a brick at you to get your attention.

    Life whispers in your soul and speaks to your heart. Sometimes, when you don't have the time to listen... Life throws a brick at your head.

    It's your choice: Listen to the whispers of your soul or wait for the brick!

    What do you use to unlock your cellphone? A password? A fingerprint? Or simply a glance?

    On September 12, 2017, Apple introduced its iPhone X, which has an eye-catching feature—Face ID.

    With Face ID, Apple says, you can unlock your new iPhone by just looking at it. It is powered by a so-called TrueDepth camera system built into the front of the iPhone X.

    When the camera system sees a person's face, it uses 30,000 unseen dots to “map” the shape and outline of the face. A mathematical model of the face will then be created and stored in the phone.

    The next time the person looks at the iPhone X, the same dots are mapped onto his or her face and compared to the stored model. If the two match, then the phone unlocks. This happens in less than a second.

    Apple says the system is smart. If you change your hairstyle, put on sunglasses or makeup, or use the phone in the dark, Face ID still works.

    Although the technology sounds fancy, there are still concerns. For example, will Face ID work for twins?

    According to Apple, the chance of others to unlock your iPhone X using Face ID is one in a million. Face ID can tell the difference between twins, but the error rating（出错率）rises. So one would need to set a password then.

    Apple also emphasizes that Face ID only unlocks when you stare at it. It is what Apple calls “attention aware”. So the phone won't unlock if you are just glancing at the phone for the time. It won't work either if someone puts the phone at your sleeping face or your photo.

    For thousands of years, people thought of glass as something beautiful to look at. Only in large glass windows. Glass bottles and jars that hold food and drink allow us to see the contents. Glass is used to make eyeglasses, microscopes, telescopes, and many other extremely useful and necessary things.

    Until the Second World War, most of the glass used for optical (光学的) instruments was imported from Europe. However, during the war Americans could not get European glass, and they were forced to make their own. Therefore, new kinds of glass were developed that had been previously unknown. These new effects were achieved by mixing other chemical elements with the sand. Some of the new glass is very strong and can resist many kinds of shocks. Legend (传说) has it that a kind of very hard glass was invented by a Roman who showed his discovery to the Emperor. When the Emperor saw the glass he feared that it would become more valuable than gold and sliver, making his treasure worthless. Therefore, he had the glass-maker killed, and the secret was not discovered again for hundreds of years.

    In the present century, safety glass was invented for use in modem cars and planes. Safety glass is made by placing a layer of plastic between two layers of plate glass. When the outside layer of glass is broken, the pieces do not scatter (散开) and injure people. Some glass of the type is strong enough to resist bullets (子弹).

    Although nowadays plastics have replaced glass under conditions where glass might be easily broken, there are new uses being developed, for the greatest advantage of glass is that its component (组成的) parts are inexpensive and can be found all over the world.

    With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dump, makes me feel good and warms my heart.

    How would you feel if you could not joke around with your wife, husband, child, co-worker, neighbor, close friends, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is common courtesy(礼貌)to speak to others that are around you.

    I know of a few people that don't have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?

    Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to ignore the sadness and bring a little light into our lives. So, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.
