I had to knock on the taxi to get his attention. Finally, the driver, a man about 60, looked up from behind the wheel and apologized, “I'm sorry, but I was reading a letter.” He sounded as if he had a cold or a cough.

    Since I was in no hurry, I told him to finish his letter. He shook his head, explaining that he had already read it several times and almost knew it by heart. Curious, I asked whether it was from a child or maybe a grandchild. “This isn't family,” he replied. “though he might just as well have been a regular member of the family. Old Ed and I grew up together.”

    They were always friends. But since he moved away from the neighborhood 30 years ago, it'd generally just been postcards at Christmas time between them. A couple of weeks ago, Ed died. “I should have kept in touch.” He repeated this, more to himself than to me. To comfort him, I said sometimes we just didn't seem to find the time. “But we used to find the time,” he said. “Take a look.” He handed the letter over to me.

    The first sentence “I've been meaning to write for some time, but I've always delayed it.” reminded me of myself. It went on to say that he often thought about the good times they had had together. When I read the part where it said “Your friendship really means a lot to me, more than I can say because I'm not good at saying things like that”, I found myself nodding in agreement.

    We had gone several kilometers and were almost at my hotel, so I read the last paragraph: “So I thought you'd like to know that I was thinking of you.” And it was ended with “Your Old Friend, Tom.”

    “I thought your friend's name was Ed,” I said.

    “I'm Tom,” he explained. “It's a letter I wrote to Ed before I knew he'd died. I never put it in the mailbox. I guess I should have written it sooner.” His face was pale as he wiped his eyes with a handkerchief.

    When I got to my hotel room I didn't unpack right away. I had to write a letter and post it.

    In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse（诅咒）;in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets（药丸）that contained mercury（水银）, believing that it would make them immortal, but they died afterward.

    Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?

    An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.

    The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars（毛毛虫）, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.

    "Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."

    A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.

    The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances（物质）that we regularly ingest（摄入）-chili, coffee and chocolate-owe their special flavors or stimulating（提神的）effects to chemicals that plants make to poison insects.

    Ahead of so-called Singles' Day on the 11th of this month，2013, online sales have already begun peaking.

    The leading e-business platform, tmall.com, has promoted(促销) its fifty-percent-off discount to attract consumers. They are also trying to attract buyers through social media. Vice President of tmall.com Wang Yulei says more than 20 thousand online stores have joined the Double 11 Day sales. But this number has doubled. The final number of how many products going to be on sale has not been known yet. But so far, many more products planned to be put on shelves with discounts.

    During last year's Singles' Day, tmall.com, together with taobao.com, reached a record of 19.1 billion yuan in sales, which considered a milestone in the e-business history of China.

    Singles' Day was first started by Chinese college students in the 1990s as the opposite of Valentine's Day, a celebration for people without romantic partners. The timing was based on the date: Nov. 11—or double 11—for singles. Single young people would treat each other to dinner or give gifts to show love to someone and end their single status.

    But now, the Singles' Day has been promoted as a kind of grand craze just for the shopping season, thanks to thousands of discounted products being promoted online.

    Taobao.com was the first big e-retail platform which used the double 11 idea to promote sales. Taobao.com reached one million yuan worth of sales on that day in 2009, when they first promoted the Singles' Day idea. In 2010, the sales increased to 936 million yuan. The figure climbed up to 5.3 billion yuan in 2011, putting huge demand on shipping services. The figure doubled in 2012.

    E-commerce is considered to be replacing the traditional retailing industry, but the reality is both sides are learning from each other.

Be careful on January 8^th — It's officially the most dangerous day of the year. The insurance company Hyperion has studied accident statistics(统计数字) and has found that there are more accidents on January 8^th than on any other day.

    Accidents are certainly more likely to happen at particular times of the year. One general rule is that more accidents happen in winter months, because risk increases in bad weather. In 2004 and 2005 Hyperion found that the worst day was January 8^th, with 298 accidents reported to them. March 3^rd was the safest day, with only 89 reports. Six of the ten worst days for driving were in January.

    It's clear that icy and snowy conditions are dangerous, but some other statistics are puzzling. A British Medical Journal report in 2001, for example, found that hospital admissions(住院) were always higher than usual on Friday the 13^th.

But it is not only when Friday falls on the 13^th that it is a dangerous day. Four of the top ten worst days for accidents last year were Fridays — perhaps because everyone is rushing home for the weekend — while Thursdays are the safest day of the week.

At what time of the day is an accident most likely to happen? The Health and Safety Authority found that people are most likely to have an accident at 11.00 a.m., while the safest time of day is between 4.00 and 5.00 a.m. — probably because most people are in bed!

    Finally, good news for Harry Potter fans. Doctors at the John Radcliffe Hospital in Oxford noted that fewer children were in hospital on the weekend when Harry Potter books were available to the public. Casualties(伤亡人员) fell by over 50% when the last two books went on sale. So if you want to be really safe, you should read a Harry Potter book in bed, at around 5.00 on a Thursday morning, in summer.

    Often people use laptops(手提电脑) on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.

    Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. Besides, they will be able to use e-mail to "speak" with their teachers, their classmates and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees—anywhere at all!

    Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. Also, the portable(便携式的)computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are also testing laptop programs at other universities, too.
