Four years ago, we asked ourselves: what if we could create a shopping experience with no waiting in lines and no checkout? Or could we create a physical store where customers could simply take what they want and go? Our answer to those questions is Amazon Go, where you could experience the idea of "just walk out shopping".

    Amazon Go is a new kind of store with no checkout required. We created the world's most advanced shopping technology, so you never have to wait in line. With our "just walk out shopping" experience, simply use the Amazon Go app to enter the store, take the products you want, and go! No lines, no checkout.

    Our checkout-free shopping experience is made possible by the same types of technologies used in self-driving cars: computer vision, sensor fusion, and deep learning. Our “ just walk out technology ” automatically detects when products are taken from or returned to the shelves and keeps track of them in your virtual cart. When you have done shopping, you can just leave the store. Shortly after, we'll charge your Amazon account and send you a receipt.

    We offer delicious ready-to-eat breakfast, lunch, dinner, and snack options made fresh every day by our on-site chefs and favorite local kitchens and bakeries. Our selection of food stuff ranges from bread and milk to cheeses and locally made chocolates. You'll find well-known brands we love, plus special finds we're excited to introduce to customers. For a quick home-cooked dinner, pick up one of our chef-designed Amazon Meal Kits, and you can make a meal for two in about 30 minutes.

    Our 1,800-square-foot shopping space is conveniently compact, so busy customers can get in and out fast. It is located at 2131, 7th Ave, Seattle, WA, on the corner of 7th Avenue and Blanchard Street. All you need is an Amazon account, a supported smart phone, and the free Amazon Go app.

    Amazon Go is currently only open to Amazon employees in our testing program, and will be open to the public soon.

    Modern life is impossible without travelling. The fastest way of travelling is by plane. With a modern airline you can travel in one day to places which it took a month or more to get to hundred years ago.

    Travelling by train is slower than by plane, but it has its advantages. You can see the country you are travelling through. Modern trains have comfortable seats and dining-cars. They make even the longest journey enjoyable.

    Some people prefer to travel by sea when possible. There are large liners and river boats. You can visit many other countries and different parts of your country on them. Ships are not so fast as trains or planes, but travelling by sea is a very pleasant way to spend a holiday.

    Many people like to travel by car. You can make your own timetable. You can travel three or four hundred miles or only fifty or one hundred miles a day, just as you like. You can stop wherever you wish where there is something interesting to see, at good restaurant where you can enjoy a good meal, or at a hotel to spend the night. That is why travelling by car is popular for pleasure trips, while people usually take a train or plane when they are travelling on business.

    Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: "Cinderella"(《灰姑娘》).

    "Cinderella" made more like $70 million in ticket sales when it opened last weekend. But the movie got a mixed reaction. David Rooney of The Hollywood Reporter praised the movie and said, "Anyone will find something to enjoy in it." Steven Rea of The Philadelphia Inquirer called the movie "a winning re-do." Richard Corliss of Time magazine wrote that "Disney finally got Cinderella right." Other people were not as happy with the movie. Sara Stewart of the New York Post wrote, "This Cinderella is all dressed up with nowhere very interesting to go."

    Although different people think differently towards the movie, what is clear, however, is the movie's business success. It is not only popular in the theaters but also in sale. And Disney has widened its usual market for "Cinderella" products.

    There are products connected to the Disney movie targeted(面向) not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo worked with Disney to create "Cinderella's shoes." You can buy them for about $5,000. At that price, you would not want to lose one at the party, even if that is the way you get your prince(王子).

    The makeup(化装品) company MAC quickly sold all its products connected to "Cinderella." HSN is a popular website selling clothing and objects for the home. The marketer is now also selling "Cinderella" products.

    So, is there anything left for the children, those people we think of as the traditional audience for the age-old tale? Yes, you can find toys and other children's products at the American store JC Penney. Of course, you can also visit a Disney store.

    When I was five or six years old, I remember watching TV and seeing other children suffer in other parts of the world. I would say to myself," When I grow up, when I can get rich, I will save kids all over the world."

    At 17, I started my career here in America, and by the age of 18, I started my first charity( 慈善) organization. I went on to team up with other organizations in the following years, and met, helped, and even lost some of the most beautiful souls, from six-year-old Jasmina Anema who passed away in 2010 from leukemia(白血病), and whose story inspired thousands to volunteer as donors, to my grandmother, who lost her battle with cancer in 2012, and her death is the very reason and the driving force behind the Clara Lionel Foundation(CLF). We're all human. And we all just want a chance: a chance at life, a chance in education, a chance at a future, really. And at CLF, our mission is to impact as many lives as possible, but it starts with just one.

    People make it seem too hard to do charity work. The truth is, you don't have to be rich to help others. You don't need to be famous. You don't even have to be college educated. But it starts with your neighbor, the person right next to you, the person sitting next to you in class，the kid down the block in your neighborhood. You just do whatever you can to help in any way that you can. And today, I want to challenge each of you to make a decision to help one person, one organization, one situation that touches your heart. My grandmother always used to say. "If you've got a dollar, there's plenty to share."

Students from Oceanside High School in Rockland will be able to sleep in a little longer from this autumn.

Regional School Unit 13 Superintendent (负责人) Lew Collins said during the school's Thursday night meeting that the schedule (时间表) for the schools will be changed. Oceanside East and West will start a half hour later, at 8 a.m. for their new school year.

Research has shown that teenagers' brains are often not fully awake at 6:30 a.m. Collins said the schedule, which is used to get students to school for classes that begin at 7:30 a.m., calls for some to get on buses before 6 a.m. to get to school on time. Teachers are having meetings at 6:40 a.m., which is too early, he thinks.

Collins visited the high schools in Rockland and asked students when they would like classes to begin. Most of them said 8:00 a.m. "I was surprised. I thought they would have said 9:00 or 10:00," he said.

The National Sleep Foundation says on its website that teenagers' biological clocks (生物钟) are designed to stay up later and get up later. The Foundation called for schools to change their schedules, which means a later start as well for elementary students (小学生).

We do not have enough buses to run, since all the high school and elementary school buses run almost at the same time, Collins said. He suggested, "We should buy six more buses and get six more drivers to keep the new schedule working."

Elementary school classes in Rockland now start at 8:30 a.m., but will be moved to 8:45 a.m., starting in the autumn. "I know this is a problem for working parents, but we will see what we can come up with," said Jane Brown, a teacher at Bardonia Elementary School. "Anyway, I believe if students get more sleep they'll be more ready to learn when classes start," she added.

Nowadays, countries are eager to get more electric cars on the road because moving away from gas-powered vehicles is vital to fighting climate change. China says that most new vehicles sold by 2035 will be electric. The United Kingdom will ban new gas-powered cars in 2030. One of the world's major automakers, General Motors (GM), announced that it would stop selling gas-powered cars by 2035. 

The key to an electric future is batteries. Automakers are racing to pack the most energy into the smallest one. The lithium-ion battery is what powers our mobile devices, which can be recharged again and again. Making these batteries has an environmental cost. Lithium is taken from the earth, like the oil used to make gasoline. But the long-term cost is much smaller. "Once you burn gasoline, you can't recycle it," says Jessika Trancik, a researcher at the Massachusetts Institute of Technology. "But when you use up a battery, you can still recycle the material."

It's up to governments to make electric cars accessible to everyone. National policies can help. In the United States, an electric Chevy Volt costs about $35, 000. Trancik says charging stations must also be made widely available. As part of an effort to fight climate change, America plans to build half a million of them in the US by 2030. She hopes enough charging stations will be built soon. "It's important to put chargers where many different people can have access to them," she says, "not just wealthier people."

Last year, almost 5% of approximately 67 million new cars sold world widewere electric. For Venkat Viswanathan, a professor of Mechanical Engineering at Carnegie Mellon University, green electricity is part of the solution to climate change, and electric cars are just the beginning. He sees a future of solar powered homes and electric flying cars. "Soon, a plug in vehicle might be as cheap as a gas-powered car. It is now abundantly clear that electric is the future," he says. "It will be a totally new world."
