Many people now have problems with sleep. Drinking milk is 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.

1.According to the text, the mice fed with daytime milk ________.

A. started sleep more easily

B. were more anxious

C. were less active

D. woke up later

2.Which of the following is true of melatonin according to the text?

A. It’s been tested on mice for ten times.

B. It can make people more energetic.

C. It exists in milk in great amount.

D. It’s used in sleeping drugs.

3.What can be a suitable title for the next?

A. Night Milk and Sleep

B. Fat, Sugar and Health

C. An Experiment on Mice

D. Milk Drinking and Health

4.How does the author support the theme of the text?

A. By giving examples.

B. By stating arguments.

C. By explaining statistical data.

D. By providing research results.

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?

A. The cause of the study.

B. The function of the caps.

C. People’s reactions to the study.

D. Some details of the study.

Forget drinking countless glasses of water or getting your beauty sleep．The secret of looking young is simply to stay out of the sun．

A study of hundreds of women has revealed that those who avoided the sun’s rays looked up to 20 years younger than they actually are. However, other supposed rules for a youthful complexion, from drinking lots of water to sleeping well and exercising regularly, failed to hold back the hands of time.

Only keeping out of the sun, and wearing sunscreen when this wasn’t possible, made a difference, the American Academy of Dermatology’s annual conference will hear today.

The finding comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun-loves. When researchers from Massachusetts General Hospital in the US guessed how old the women were, they found those who took care in the sun tended to have aged more slowly.

Four lucky women had so few wrinkles and age spots and such a glowing complexion，that they appeared to be twenty years younger than they really were．

Researcher Dr．Alexa Kimball said the popular belief that we drink lots of water to stay healthy is false and the body is “pretty good” at judging how much we need．Previous research by the British Nutrition Foundation reached a similar conclusion．

It isn’t clear why the women who slept well didn’t have younger-looking skin．But it may be that the question they were asked was too narrow and didn’t consider their long-term sleep patterns．

1.Which way can help women stay younger according to the study?

A. Having a good sleep． B. Drinking plenty of water．

C. Taking exercise regularly． D. Keeping out of the sun．

2.How did the researchers know the finding about women of all ages?

A. Through calls． B. Through games．

C. By quizzes． D. By interviewing face to face．

3.What’s the main purpose of the passage?

A. To introduce a good way to make women look younger．

B. To explain how scientists carried out the research．

C. To prove people’s previous ideas are true．

D. To persuade women to change their long-term sleep patterns．

4.This passage is most probably taken from______________．

A. a school textbook． B. a science fiction．

C. a reference book． D. a science paper．
