About 45 percent of Americans don’t get enough sleep, according to a recent survey. However, the benefits of getting enough sleep far outweigh the thrill of watching TV for one more hour or surfing the web. Getting a better night’s sleep will help you lose or keep your weight more effectively. Try these simple steps to improve your quality of sleep.
Take time to relax
So many of us go-go-go until it’s time for bed, but it’s important to take time to slow down and relax before sleeping. Do relaxing things, such as listening to soothing (抚慰的) music or deep breathing. Avoid stimulating (刺激的) activities such as writing e-mails, talking on the phone and watching TV. Some guidelines (指导方针): no e-mail after 8 p.m. and no TV or phone calls after 9 p.m..
Darker is better
Your body regulates your sleep cycle in response to the presence and absence of light, so dim the lights as evening approaches. Try getting ready for bed by candlelight. When you’re ready to sleep, make sure your room is as dark as possible.
Put your thoughts to bed
We all need time to process our day, but bed is not the place to do it if you want to sleep well. Take 10 to 15 minutes to record your thoughts in a journal. This effective technique will capture what’s in your mind so you don’t lie awake. Tell yourself you’re putting your thoughts to bed so that you can go to bed.
No sugar or alcohol before bed
These may wake you up. If you need a snack before bed, make it protein.

Today, ultrasonic(超声的) waves are being put to work in laboratories and factories. If an ultrasound generator is placed in a liquid, the waves move the liquid back and forth hundreds of thousands of times each second. This causes materials to mix quickly or to dissolve(使分解，使溶解) in liquids. Paint manufacturers(制造商) use ultrasound to do a better job of blending colors. The companies that make film for your camera find that mixing chemicals by the use of sound waves will produce a more sensitive film.
The new lightweight(轻量的) type of washing machine uses ultrasonic waves to get clothes clean. Its special ultrasound generator is put into a pail of soapy water containing the soiled clothes. The sound waves drive the soapy water back and forth through the cloth so fast that everything is soon clean. There is also a new kind of dishwasher that works in much the same way.
Ultrasonic waves can shake a liquid so fast that tiny holes form all through it. The liquid is actually torn apart by this action. Almost as soon as these holes are made, they fall together again. The result is a powerful pounding action. In the dairy industry this is used for the double purpose of making homogenized(使均匀，使匀质) milk and sterilizing(使无菌) it at the same time. If you look at some raw milk with a microscope, you find that it is made up of little drops of butter fat floating around in a watery liquid. In order to make milk easier to digest, these fat droplets(微粒) may be broken up by forcing the milk through very small openings. The result is called homogenized milk. When the ultrasonic method is used, the sound waves not only break up the droplets but also kill the germs in the milk by pounding them to pieces. (from www.nmet84.com)

Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can’t be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone in bed, taking no notice of the worms. But is it interfering(干涉) with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.
Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance(机械维修，保养) as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results will be. And at what point should you stop to treat the old body? Is it morally right to try to push off death by seeking the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You can’t ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try, on the principle that while there’s life, there’s hope.
When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun.

Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful(有害的) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers(志愿者) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin need to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levers of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a verve activity(神经活动), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.According to Professor Barnes, theobromine ______.
| A．cannot be as effective as codeine |
| B．can be harmful to people’s health |
| C．cannot be separated from chocolate |
| D．can be a more effective cure for coughs |
What was used in the experiment to cause coughing?
| A．Theobromine. | B．Codeine. | C．Capsaicin. | D．Placebo. |
We learn from the text that volunteers in the experiment _____.
| A．were patients with bad coughs |
| B．were divided into the three groups |
| C．received standard treatments |
| D．suffered little side effects |
Which of the following would be the best title for the text?
| A．Codeine: A New Medicine | B．Chocolate May Cure Coughs |
| C．Cough Treatment: A Hard Case | D．Theobromine Can Cause Coughs |
