Cleverness is a gift while kindness is a choice．Gifts are easy—they're given after all．Choice can be hard．

    I got the idea to start Amazon 16 years ago．I came across the fact that the Internet usage was growing at 2300 percent per year．I'd never seen or heard of anything that grew that fast，and the idea of building all online bookstore with millions of titles was very exciting to me. I had just turned 30 years old，and I'd been married for a year．I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't and I wasn't sure what to expect．MacKenzie told me I should go for it．As a young boy，I'd been a garage inventor．I'd always wanted to be all inventor，and she wanted me to follow my passion．

    I was working at a financial firm in New York City with a bunch of very smart people and I had a brilliant boss that I much admired．I went to my boss and told him I wanted to start a company selling books on the Internet．He took me on a long walk in Central Park，listened carefully to me，and finally said，“That sounds like a really good idea，but it would be an even better idea for someone who didn't already have a good job．”That 1ogic made some sense to me，and he convinced me to think about it for 48 hours before making a final decision．Seen in that light,it really was a difficult choice，but finally，I decided I had to give it a shot．I didn't think I'd regret trying and failing．And I suspected I would always be haunted by a decision to not try at all.

    After much consideration ，I took the less safe path to follow my passion ，and I'm proud of that choice．For all of us，in the end，we are our choice．

    The kids in this village wear dirty, ragged clothes. They sleep beside cows and sheep in huts made of sticks and mud. They have no school. Yet they all can chant the English alphabet, and some can make words.

    The key to their success: 20 tablet computers(平板电脑) dropped off in their Ethiopian village in February by a U.S. group called One Laptop Per Child.

    The goal is to find out whether kids using today's new technology can teach themselves to read in places where no schools or teachers exist. The Massachusetts Institute of Technology researchers analyzing the project data say they're already amazed. “What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten,” said Matt Keller, who runs the Ethiopia program.

    The fastest learner—and the first to turn on one of the tablets—is 8-year-old Kelbesa Negusse. The device's camera was disabled to save memory, yet within weeks Kelbesa had figured out its workings and made the camera work. He called himself a lion, a marker of accomplishment in Ethiopia.

    With his tablet, Kelbasa rearranged the letters HSROE into one of the many English animal names he knows. Then he spelled words on his own. “Seven months ago he didn't know any English. That's unbelievable,” said Keller.

    The project aims to get kids to a stage called “deep reading,” where they can read to learn. It won't be in Amharic, Ethiopia's first language, but in English, which is widely seen as the ticket to higher paying jobs.

    China is starting to blacklist poorly-behaved tourists as it seeks to rescue the image of its citizens as holidaymakers.

    According to a regulation by the China National Tourism Administration (NTA) that entered effect this week, tourists will be blacklisted for offences including acting antisocially on public transport, damaging private or public property, disrespecting local customs, damaging historical exhibits on purpose or engaging in gambling or pornographic activities. Records will be kept in a two-tired system: provincial-level tourism authorities are responsible for cases under their jurisdiction（管辖区域）while the NTA will be in charge of a nationwide register. People will be .blacklisted for two years after they offend, according to the regulation.            

    The NTA said tourism authorities will inform blacklisted tourists and “propose correction measures in order to mitigate the negative impact”. It also said that tourism authorities reserve the right to report such violations to public security, customs and transport authorities as well as the central bank's individual credit department.

    The regulation comes amid (在……之中) growing concern about the ill manners of Chinese tourists both at home and abroad. In 2013, a Chinese tourist wrote his name on a relief carving in Luxor, Egypt. In December, a Chinese passenger threw a cup of hot instant noodles at a flight attendant on an international flight. Chinese tourists have been fined or put into prison for carrying prohibited items or purchasing wild animal products.

    You often can choose a private setting when you browse(浏览) the internet. But be forewarned: It may not afford nearly as much privacy as you expect. That's the finding of a new study.

    Major web browsers, such as Google's Chrome and Apple's Safari, often a private-browsing option. It's sometimes referred to as “incognito.” This option lets you surf the Internet browser and saves a record into its history of each page that you visited. And what sites you visit won't affect the suggestions your browser makes the next time you're filling out an online form.

Many people believe—incorrectly— that the incognito setting protects them more broadly. Most believe it even after reading a web browser's explanation of the incognito mode.

    For instance, a new study had 460 people read web browsers' descriptions of private browsing. Each person read one of 13 descriptions. Then the participants answered questions about how private they thought their browsing would be while using this tool. The volunteers didn't understand the incognito mode. This was true no matter which browser explanation they had read. The researchers reported their findings on April 26 at the 2018 World Wide Web Conference in Lyon, France.

    More than half of the volunteers thought that if they logged into a Google account through a private window, Google wouldn't keep a record of their search history. Not true. And about one in every four participants thought private browsing hid their device's IP address. That's wrong, too.

    Blase Ur was one of the study's authors. He's an expert in computer security and privacy in Illinois at the University of Chicago. Companies could clear up this confusion by giving better explanations of the incognito mode, his team says. For example, the browsers should avoid vague（模糊).The web browser Opera, for instance, promises users that “your secrets are safe.” Nope Firefox encourages users to “browse like no one's watching.” In fact, someone might be.

    Traveling can be a fun way to gain life experiences, especially during Spring Break-a week-long school vacation in the United States. But what if you're a student and don't have enough money for a trip？Don't worry. Here are some useful suggestions.

    Save：This probably is the most important preparation for traveling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

    Plan ahead：Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security and savings.

    Do your homework：No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

    Plan sensibly：Write down how much you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

    Travel in groups：Find someone who is interested in visiting the same places. By traveling with others you can share costs and experiences.

    Work as you go：Need more money to support your trip？Look for work in the places you visit.

    Go off the beaten path：Tourist sites may be expensive. You may want to rethink your trip and go to a less﹣known area. Smaller towns can have many interesting activities and sights.

    Pack necessary things：The most important things to take are not always clothes.

Remember medicine in case you get sick, and snacks in case you cannot find a cheap restaurant.

    Use the Internet：The net can help to save money. Some useful websites include www.travelcity.corn, www.bargainslowestfare.corn and www.economictravelcity.com.

    By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.

    Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined (限于) to the aged. There may be a million or more people under the age of 65 suffering from the disease.

    At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic (器官的) disease, that destroys brain cells.

    Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking, and then the patient's memory begins to fail. He may forget dates, numbers, names and plans.

    As the disease progresses, the patient may not recognize family and friends. These symptoms(症状) often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.

In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.

    Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus (病毒). It may be caused by a poisonous substance(物质) in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.
