2.A Good Night's Steep
Sleep plays a vital role in good health and well-being throughout your life.While you're sleeping,your brain is forming new pathways to help you learn and remember information.Although we all kno the importance of getting a good night's sleep,not all of us know the best way of getting it.A sleep expert,
Phil Atherton,gave some top tips for getting the most out of the night,which will leave you ready for action in the morning.
According to Phil Atherton,not eating a large meal before bedtime is important for getting a good night's sleep.The time difference between eating and sleeping should be at least three hours.So you'd better avoid eating any food three hours before bed,as it will lower your blood sugar during sleep and
help minimize damage from too much sugar floating around.
It's also important to find ways to prepare your body for sleep.You can follow a routine like trying not to expose yourself to too much artificial light within 1hour before bed,as your brain uses light to help set internal"body clock".Although it might seem unnatural to schedule your sleep,the purpose is to send a signal to your body and mind that it's time to sleep.
Another way to prepare your body for sleep is to get into a relaxed state by taking a bath or listening to soft music.Both of them will help to take the mind off the daytime pressures.
Having a suitable bed,especially a suitable mattress (床垫),is necessary for a good night's sleep.Sleep is a personalized activity,and we all adopt different sleeping positions.Finding the mattress that suits you will reduce back pains that can result from a poor sleeping position.The bed should be four to six inches longer than its tallest user,allowing for space to move around.
The recent research is pretty clear that a good ight's sleep in a major component of good health.Since the start of the 21st century,studies have linked a lack of sleep to many diseases,such as diabetes and obesity.Taking action now will lead to long-term benefits for you and those around you.
28.What does the author intend to tell us in the passage?D
A.When to start a sound sleep.
B.Why to form a good habit of sleeping.
C.What to do with sleep problems.
D.How to get a good night's sleep.
29.According to the author,before going to sleep,you'd betterC.
A.relieve your pain in the back      
B.check your blood sugar
C.free yourself from tension         
D.record your biological clock
30.What does the underlined word"it"in Paragraph 2refer to?A
A.Not eating food.
B.Taking a meal.
C.Not sleeping well.
D.Having a good sleep.

14.Milk was one of the main foods of people long before history was written.It will probably keep on being one as long as there are animals that give milk.
Even the word"milk"is very old.It comes from Sanskrit (梵文 ),one of the oldest languages known to man.A very old picture of milking has been found.It was drawn more than five thousand years ago.
In the years long ago,people got their milk from their own animals.But later new inventions made the milk industry a big business.In 1851Gail Borden found a way to take some of the water out of milk.This made it keep much longer.Four years later,Louis Pasteur introduced a way to kill the bacteria (细菌 ) in milk.Next,a special milk bottle was made.This was followed by the invention of machines that could fill bottles with milk.
These discoveries had a great effect on the milk industry.They meant that milk could be stored longer.
Some people believe that milk drinking will become less popular than it has been.But remember how long milk has been an important food and think of many ways in which it is useful.It seems safe to say that milk industry will always be important.
21.Milk is the most possibly to be a food of oursD.
A.where there are animals that can give milk.
B.if there are animals and people in the world.
C.if we want to eat every day.
D.as long as there are animals that can give milk.
22.The word"milk"comes fromD.
A.China     
B.England     
C.Japan     
 D.India
23.The word"milking"in the second paragraph meansC.
A.牛奶     
B.喝牛奶      
C.挤奶      
D.脱脂
24.Milk industry will be always an important one becauseC.
A.milk drinking is very popular in the world.
B.milk is a food of good taste and there are many cows.
C.milk has been an important food for a long time and is widely used.
D.milk can be stored (kept) longer and carried to other countries.
