We had known for along time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at special time. The question is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept in constant (持续的)darkness. We might expect that the flowers ,without any information about the time of the day, did not open as they usually do. In fact, they continue to open at their usual time. This shows that they have some special ways of knowing the time. Their sense(感觉) time does not depend on information from the outside world. It is inside them: a kind of "inner (内部的)clock". This discovery may not seem to be very important. However, it is later found that not just plants but animals have this "inner clock" which control(控制)the working of their bodies and influences their activities. Human beings, then, are also influenced by it. Whether we wish or not, itaffectssuch things in our life as our need for sleep or need for food.

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!
