Gauri Nanda sees a wearable computer as a handbag—one that’s built out of four-inch squares and triangles of fiber, with tiny computer chips embedded(嵌入) in it. It looks, feels and weighs like your typical leather purse.
That’s where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf.
Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.
Here’s how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will notify the computer that you’ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring—and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years--- making for a booming market for wearable computers that don’t like something out of science fiction.

In November of 2007, NBC Universal launched its first official Green Week. Throughout the week, NBC Universal presented over 150 hours of environmentally themed content across multiple platforms.
Now, NBC Universal is proud to present Green Week 2009. With a new theme and message of "Green Your Routine," Here at NBC and NBC.com we celebrate our talent in the "The More You Know" PSA campaign, presenting green-themed tips in several of our daytime life, among several other features here on the "Green Your Routine" site.
Fashion & Beauty
Throw a clothes swap party! Dying for that sweater your friend wore the other day? Well, maybe she'll trade for that old T-shirt you have. Here's a website that helps you organize a swap party (www.swapstyle.com), or just plan your own!
Go natural with organic make-up. Applying unnatural products directly on your skin wasn't exactly what nature intended. Try switching to a line of organic make-up and cosmetics for a different way to bring out your natural beauty.
Home
Drop a brick in your toilet tank! Literally! According to the EPA, flushing makes up 30 percent of a household's water use (about three to six gallons per flush). By placing a brick in your toilet tank, you can help to conserve the amount of water used during each flush.
Wash clothes efficiently. 90 percent of the energy used in washing clothes is to heat the water. You can reduce your energy bill by washing in cold water and hanging items to dry.
Work
Print smarter. Printing and copying can be one of the most costly operations in any office. To save on ink and paper costs, print double-sided and try to fit more than one page on a sheet. More printing tips can be found here: lifehacker.com
Turn off your computer. Do you leave your computer on overnight? If so, you're using up a good amount of electricity. When you can, try turning off your computer and the power strip it's connected to. If you can't, at least shut off your monitor. Remember, screen savers don't save energy.
Transportation
Organize a carpool. There are many benefits to carpooling. You save on gas, reduce wear and tear on your car, and you get to ride in the HOV lanes. Get connected with your neighbours and co-workers to start sharing rides and check out this website for more tips: www.erideshare.com.
Lose the car, get a bike. If you live close to where you work, try taking a bike instead of driving. You'll keep in shape and save on gas!
Every small step and effort makes a difference! Be sure to GREEN YOUR ROUTINE!

If you struggled to get up for work on Wednesdays, there could be a good reason--it is the day our mood reaches its lowest point. Monday has traditionally been thought of as the most depressing day of the week but according to psychologists, midweek gives more cause for concern in reality. Wednesday represented the lowest point in the week as people were furthest away from the weekend that has either just gone or is coming up and often feel too tired to go on with work.
However, psychologists have found that, on average, people's moods remain about the same on each day throughout the week.
To start their research, the University of Sydney scientists asked around 200 people what they thought their mood would be on each day of the week.
Most said their worst moods were on Monday mornings and evenings but they became increasingly cheerful as the week went on, with their best moods falling on Friday and Saturday mornings and evenings.
When asked why they believed that Friday and Saturday were best, respondents said they saw them as less-structured days when they could choose how to spend their time.
The psychologists then asked a further 350 people how they felt each day.
They found that, on average, people's moods remained about the same on each day throughout the week.Mondays were not as depressing as they had feared and Fridays and Saturdays were not as exciting as predicted.
Professor Charles Areni, who led the study, said the day-of-the-week stereotypes (陈词滥调) stem from a cultural belief that people are generally happier when they are free to choose their activities compared to when they are engaged in paid work.
In reality, he said, weekends do not often see moods change because they are frequently dominated by productive activities that may require large amounts of energy and begin to feel tired like work. "Day-of-the-week stereotypes like Monday morning blues and Thank God It's Friday are largely illusions," he said.
1. _________ has always been thought as the unhappiest day of a week.
A. Monday B. Wednesday C. Friday D. Sunday
2.People don’t like Wednesday because ________.

3. Which of the following is the finding of the research mentioned in the passage?
A. All of the people asked admitted that on Monday they had the worst moods.
B. Saturday and Sunday were the best because people could plan their time freely.
C. There was no sharp difference in people’s moods between each day of the week.
D. Different people had different ideas about which day was the worst in a week.
4. Charles Areni believes that the day-of-the-week stereotypes results from________.
A. the productive activities requiring a large amount of energy
B. the cultural belief that doing paid work is usually less pleasant than doing freely chosen work
C. the illusions of day-of-the-week stereotypes
D. the days in a week when our mood reaches its lowest points
Freda Bright says, "Only in opera do people die of love." It's true. You really can't love somebody to death. I've known people to die from no love, but I've never known anyone to be loved to death. We just can't love one another enough.
A heart-warming story tells of a woman who finally decided to ask her boss for a raise in salary. All day she felt nervous and apprehensive. Late in the afternoon she summoned the courage to approach her employer. To her delight, the boss agreed to a raise.
The woman arrived home that evening to a beautiful table set with their best dishes. Candles were softly glowing. Her husband had come home early and prepared a festive meal. She wondered if someone from the office had tipped him off, or... did he just somehow know that she would not get turned down?
She found him in the kitchen and told him the good news. They embraced and kissed, and then sat down to the wonderful meal. Next to her plate the woman found a beautifully lettered note. It read, "Congratulations, darling! I knew you'd get the raise! These things will tell you how much I love you."
Following the supper, her husband went into the kitchen to clean up. She noticed that a second card had fallen from his pocket. Picking it off the floor, she read, "Don't worry about not getting the raise! You deserve it anyway! These things will tell you how much I love you."
Someone has said that the measure of love is when you love without measure. What this man feels for his wife is total acceptance and love, whether she succeeds or fails. His love celebrates her victories and cure her wounds. He stands with her, no matter what life throws in their direction.
Upon receiving the Nobel Peace Prize, Mother Teresa said, "What can you do to promote world peace? Go home and love your family." And love your friends. Love them without measure.
