Are you having difficulty falling asleep? Try drinking a glass of warm milk. If that doesn’t work, listen to some soft, beautiful music. Still no luck? Try think about sheep jumping over a fence. If you are still awake, take a sleeping pill. People who take pills often become dependent on the drugs. So you lie awake knowing that the new workday will soon arrive. If you have been in such condition for at least one month, you may have primary insomnia(失眠症).
A new study has found that you might fall asleep more quickly and stay asleep longer if you try “cerebral hypothermia.” It is not a complex medical process. It just means cooling down your brain. Eric Nofzinger and Naniel Buysse from the University of Pittsburgh Medical School led the study. They examined twelve people who had sleeping problems. Twelve others had no sleeping problems. Each of them wore a soft plastic cap on their head at bedtime.
The caps had tubes inside filled with water. The researchers moved the water through the tubes and then changed the temperature of the water. Other studies showed that people who had sleeping problems often had more chemical reactions in the front of their brain. The researchers thought cooling down the brain might help.
On the first two nights of testing, the patients wore caps with no water. On the next two nights, the caps were worn, but the water was not cooled. Then the researchers cooled the water a little for another two nights. On the final two nights of the study, the temperature of the water was made much cooler. The researchers found that the water caps didn’ t help the patients until the temperature was about 14℃. Most of the patients fell asleep faster and slept better when the coolest water was moving around their head.
Dr Nfzinger and Dr. Buysse noted that this was only the beginning of the brain temperature study. But they believed they had discovered something important that needed more research.
1.The first paragraph is written to _________.
A. put forward the topic of the passage.
B. explain how serious insomnia is
C. tell us the causes of sleeping problems.
D. tell us the danger of having sleeping problems.
2.From the passage we know that “cerebral hypothermia” is actually _________.
A. a complex medical process.
B. a psychological treatment.
C. a simple physical treatment.
D. a difficult scientific theory.
3.In the study, researchers helped people fall asleep faster through _________.
A. increasing chemical reactions in the front of their brain.
B. making them feel safe with a cap on their head
C. asking them to drink water to cool down
D. lowering the temperature of their brain
4.What is paragraph 4 mainly about?

If you are having trouble falling asleep, you are in good company. About 65% of Americans said they have sleeping problems a few nights each week, according to a recent study by the National Sleep Foundation. Sleeping too little can lead to a higher risk of becoming fat and getting depressed(沮丧的). But before you go to a doctor for advice, it is worth examining your sleeping habits one more time. Some of your favorite evening habits may have something to do with the sleeping problems.
Setting a Bright Alarm Clock
The light of your bright alarm clock can prevent you from falling asleep. You can make your room as dark as possible. Cover the bright numbers with a book or consider buying a small travel clock. Your cellphone alarm may also do the trick.
Counting Sheep
When you just can’t fall asleep, it’s useless to stay in bed to count sheep. If you’ve been trying to fall asleep for more than 30 minutes, the National Sleep Foundation suggests you get up to do some reading or watch TV for a while. Such activities will make you sleepy. Before you know it, you’ll be going back to bed really tired.
Exercising Late at Night?
Daytime workouts(锻炼) will keep you full of energy for hours. That’s why you don’t want to exercise within three hours of hitting the sack. Fierce(剧烈的) physical activity raise your body temperature and pumps your energy level—both are bad for a good night’s sleep.
1.What can we learn from the first sentence of the passage?
A.It’s not good to fail to fall asleep at night.
B.People in a good company often have sleeping problems.
C.There are many people who have sleeping problems.
D.You should find someone to talk to if you can’t fall asleep.
2.The underlined part “hitting the sack” in the last paragraph means “______”.
A.going back home B.going to bed
C.going to the gym D.falling asleep
3.Which of the following is NOT mentioned in the passage?
A.The bad results o f getting too little sleep.
B.Why the bright alarm clock keeps you awake.
C.What to do if you can’t fall asleep after 30 minutes.
D.Why watching TV and reading books make people sleepy.
4.By writing the passage, the writer mainly wants to tell us _______.
A.why so many people can’t sleep well at night
B.how to enjoy a good night’s sleep
C.that sleeping problems are troubling more and more people
D.that people may solve their sleeping problems by some habits

Your teen is falling asleep in class
Teens have a busy morning schedule as they need to wake up and get moving very early in order to catch a bus and get to school by the required time. This means teens need to get their rest the night before or they will be too tired to learn anything at school. 1.

To prevent your teen from being sleepy in class, try these three tips:
* Set a time for “lights out” on school nights. This is never be any later than 10 p. m. and preferably 9 p.m. 3. Soft music can be on and used to help calm your teen.
* Help your teen develop a nighttime routine that involves activities that slow them down for the end of the day. 4. Turning off the computer and disconnecting from friends and the excitement of the day an hour before bedtime will also help your teen relax.
* 5. This will reinforce (增强)what it feels like to be rested and capable of accomplishing what he/she wants.
A. What’s worse, they may even fall asleep in class.

It’s a common phenomenon that modern people now have difficulty sleeping. Drinking milk is thought to be helpful. A warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.
Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety. The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night. Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.Night milk quickened the start of sleep and caused the mice to sleep longer. While the effect of cows’ milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.
Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax. Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.
