Energy Cycle

Do you find getting up in the morning so difficult that it's painful?This might be called laziness, but Dr. Kleitman has a new explanation.He has proved that everyone has a daily energy cycle.
During the hours when you labor through your work you may say that you are"hot".That's true.The time of day when you feel most energetic is when your cycle of body temperature is at this peak.For some people the peak comes during the morning. For others it comes in the afternoon or evening. No one has discovered why this is so,but it leads to such familiar words as:"Get up, John!You'll be late for work again!"The possible explanation to the trouble is he is at his tempera-ture-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.
You can't change your energy cycle,but you can learn to make your life fit it better. Habit can help,Dr. Kleitman believes.Maybe you're sleepy in the evening but feel you must stay up late anyway.Counteract your cycle to some extent by habitually staying up later than you want to.If your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour. This won't change your cycle,but you'll get up steam and work better at your low point.
Get off to a slow start,which saves your energy.Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before.Whenever possible,do routine work in the afternoon and save tasks requiring more energy for your sharper hours.

Energy cycle may be inherited from your parents.
A:Right
B:Wrong

Looking to help the environment?Consider the following simple ideas.
Turn off electrical devices when they're not being used.
Turning off,rather than leaving on stand-by,things like your TV and computer will save huge amounts of energy. With this,we can all help reduce the amount of carbon dioxide emitted into the earth's atmosphere,thereby reducing pollution and global warming.
Share your car.
Rather than traveling to work alone,why not arrange car-sharing with one or more of your friends or colleagues?To give you an example,if you drive a fashionable car,you will use more energy in a year than you would leaving your fridge open for seven years,or your TV on for thirty-two years!Imagine the savings if you shared your car with 2,3 or even 4 other people!
Refuse junk mail.
While we all complain about how much junk mail we get,we very rarely do anything about it. The mail continues to go straight from our letter-boxes into the garbage bin-with 99% of it not even opened.What can you do about this?There are various websites where you can register to receive no junk mail.As well as saving time,you'll also be doing a lot for the environment. Each year,100 million trees are used to produce junk mail. 250,000 homes could be heated with one day's supply of junk mail.
There are many other everyday changes you can make to help the environment. They will cost you nothing,and many will actually save you money!Why not give it a try?We can all help, if we really want to.

We shouldn't buy a car since it wastes so much energy.

B: Wrong
C: Not mentioned
