Why do I volunteer with Big Brothers Big Sisters of America? I have many reasons. Perhaps the biggest reason is that someone volunteered to help me. Years ago, I was on the other side of the table. I was lonely and felt kind of lost. More than once, I found myself on the wrong side of a jail cell(牢房). If someone hadn't stepped in, I probably wouldn't even be here right now.

    I've seen the work that Big Brothers Big Sisters has been doing all over the country and I'm pleased to be part of it. I've never done anything that made me prouder than my volunteering work. Big Brothers Big Sisters helped me get my head on straight. There are no words to describe the joy I get from helping somebody turn their life around.

    Don't tell anyone I said that, but volunteering is probably the fastest way to get over sadness or depression. Every time I start to feel bad, I talk to someone who needs my help and it makes me feel better and worse all at the same time. I feel better, because doing good things fills me with a sense of pride. I feel worse because I feel I have no right to complain about my situation especially when I hear what others are going through.

    I've come a long way from where I was. Volunteering is how I want to leave my mark on the world. I recommend volunteering work to everybody, especially for somebody who isn't sure where they're going in life. Helping someone find their path is often the best way to find yours.

    E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(伪装)itself as an “important message from a friend. In spite of a weekend of warnings，more than 50 000 computers at about 100 places around the world have been attacked by the virus，computer security experts said on Monday.

    The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被传染的)e-mails. Although the virus causes no serious damage to a computer，its effect was far reaching.

    To make matters worse，a similar virus called “Papa” was discovered on Monday. Papa is programmed to send out even more infected e-mails than Melissa.

    The Melissa virus comes in the form of an e-mail，usually containing the subject line“Important Message”. It appears to be from a friend. The body of the e-mail message says，“Here is that document you asked for...,don't show it to anyone else.” Attached(附)to the message is a document file.

    Once the user opens that file，the virus digs into the user's address book and sends infected documents to the first 50 addresses. E-mails from the Papa virus include an attached spreadsheet(电子数据文件)file. When the user opens that file，the virus sends 60 infected e-mails.

    The reason why this is spreading so fast is that you are getting it from people you know. You should never open documents or attachments from people you don't know. People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message.

    Please Choose Cloud Services

    May be unsure, or you do not know where to begin. Trying every Cloud service would take a lot of time and work. But, the website Reviews.com might help.

    One valuable feature is the protection of digital files, including photos, videos, documents, music and more. If the worst happens and your computer crashes, or gets lost or damaged, your files can still found in the Cloud.

    Cloud services let you access your files from almost anywhere. No need to worry about a file stored on your computer when you are away from your desk. If you have an Internet connection, you can open your files from any computer, or from a phone, when they are stored using a Cloud service.

    Using a Cloud service makes sharing files easier. If you send documents to a group using emails, you may then wonder which version everyone is working with. When sharing files using a Cloud service, everyone will see the same document and the latest version.

    The first thing to consider is the amount of storage space you need. Check how much space you are currently using on your computer and mobile devices. If your computer or phone is filled with photos and you have little free space, you may want to move your photos to the Cloud. Some Cloud services are free. But, if you need a lot of space, you will probably need one that costs money.

    Even if everyone you have ever met is a Windows user, you still probably want a Cloud service that works with many platforms. You might become friends with an Android user or start a job with a company that computers on Apple!

    People in developed countries are increasingly suffering from illnesses resulting from overeating. While starvation and hunger are still big problems in many poor countries in the world, more than 25 percent of the population in America and other western countries are obese. This doesn't just mean you are a little bit fat. It means you are more than 20 kilos overweight.

    Dr. John Colon from Ohio State University says the problem is only going to get worse.” As more women have gone out to work, you find that parents in general have less time to spend on preparing food. That's not just cooking, but also planning what to eat, doing the shopping and buying the fresh food. Families, therefore, increasingly rely on ready-made and frozen meals, which tends to be high in fat and contain a lot of additives(materials added to food to improve its taste) and sugar. The other thing is that parents seem to feel guilty about not spending so much time with their kids, so they tend to give more quickly to children's demands for things like sweets and chocolate.”

    Ben Brown. Who is a British Member of Parliament, blames the big food companies. He wants to ban any food advertising that is aimed at children. "The problem is that these companies spend millions of pounds selling food to children. It's all crisps (薯片) in the shape of dinosaurs and chocolate in the shape of Mickey Mouse. I meanwhat's going to be more fun to an sight-year-old —an ice cream with a free toy or an apple?"

    One food company thinks it has an answer to this: it has invented cheese-flavored cabbage and chocolate-flavored carrots. It developed the "Whacky Veg" with money donated by a cancer research charity, which found that a diet containing lots of fruit and vegetables helps reduce cancer. However, today's sweet-toothed kids need to be bribed(贿赂)into a healthy diet, and will only cat their greens if they taste different.

    I study English literature at university and have always been proud of Britain's literary heritage(文学遗产). Some British authors that you may have heard of are Charles Dickens and Jane Austen. These writers are famous all over the world because their books have been translated into many different languages. In the UK, their novels are celebrated as some of the best that have ever been written. We say that these novels are "classic" because they are still read and enjoyed years after their publication.

    I read classic novels because they are part of my university lessons but also because I enjoy them. They can teach you a lot about how people used to live and what society was like in the past. Novels like Hard Times by Charles Dickens remind us of the poverty in London during the Industrial Revolution while Jane Austen's fiction shows us what family life was like in the 18th century.

    Classic novels usually have memorable stories land interesting characters. One of my favourite books is Charles Dickens Great Expectations. It is about a boy called Pip who suddenly receives a lot of money from a mysterious supporter. As he grows up, his character changes: he becomes quite selfish and mean. Another important character is Miss Havisham. When she was young, her fiancé ran away on their wedding day. She lives in a dark house and still wears her wedding dress. She is a fascinating character, both sad and scary.

    Reading classic novels enriches my knowledge and life experience. And it has become part of life.

    Demand for the Chinese tech company's devices(设备) is red hot even though the country's overall market for smartphones is getting smaller Huawei's China sales rocketed more than 20% in the final quarter of 2018, and experts say that's partly due to the US govenment's global campaign against the company.

    "The latest tension between the US and China raised the patriotism(爱国主义) in Chinese consumers, said Jusy Hong, an analyst at research firm IHS Markit

    He pointed out that some Chinese companies encouraged employees to buy Huawei phones late last year. The moves were a gesture of support after the firm's chief financial officer was arrested in Canada in early December at the request of the United States.

    Huawei's booming sales show how major parts of its business continue to increase even as the United States tries to persuade other countries to shut Huawei products out of 5G wireless networks and pursues(追究) criminal charges against it. The company expects to overtake Samsung as the world's biggest smartphone maker by next year.

    Huawei sold 30 million phones in China in the last three months of 2018, nearly three times as many as Apple(AAPL), according to data published this week by research firms Canalys and IDC. Apple's sales plunged almost 20%.

    Huawei's success in China, the world's largest smartphone market, is more than about geopolitics(地缘政治). Chinese consumers love its flagship, high -end- phones because they have great cameras, cutting edge technology and cost less than the latest iPhones, according to analysts. And by offering a selection of cheaper phones, Huawei is able to target a bigger market.

    It also benefited from the troubles this year at ZTE (ZTCOF), a rival Chinese smartphone and telecommunications equipment maker. ZTE was banned by the US government from buying vital American parts for months last year.
