20.Let's face it-you're going to get a lot of well-intentioned advice from friends,parents and grandparents about your sleep.Some of this advice is going to be just wrong.
Myth 1:Sleeping late on the weekends will make up for lost sleep during the week.
Fact:Getting less than the amount of sleep that you need night after night accumulates over time and starts to create a"sleep debt".And like all debts,eventually you need to pay the price.The problem with waiting until the weekend to meet sleep needs is that in the meantime,you are paying the price of being less alert,feeling more moody,thinking slower and having less stimulation.
Myth 2:A boring teacher (or warm room,full stomach,etc.) can put teens to sleep.
Fact:If you are getting enough sleep on a regular basis,there is no teacher,math book or reading assignment in the world boring enough to make you fall asleep in class.There are basically two things that make people sleepy-not getting enough sleep and not getting good quality sleep.The environment kids are in,including the room temperature,light level and entertainment value,may unmask underlying sleepiness,but the environment does not cause it!So if you are dozing off in class,don't blame it on bad teaching.
Myth 3:Teenagers can pull an all-nighter to study and still be ready for the big test in the morning.
Fact:Teenagers are much better off studying less and getting a good night's sleep.Research clearly shows that the ability to concentrate and learn new information,as well as to work efficiently,declines sharply after being awake for 15-16hours,and continues to bottom out the longer you stay up.Plus,if the big test is at 8:00am,the problem gets even worse.That's because morning time typically represents a low energy point in the body's normal 24-hour circadian(生理节奏的) rhythm,especially in teenagers.

64.According to the passage,a student who is in a sleep debtD.
A.thinks slower but more carefully
B.must make up for the lost sleep on the weekends
C.will become more interested in fancying
D.will become bad-tempered and upset
65.According to Myth 2,which of the following is TRUE?C
A.Students who eat a lot are sleepy at class.
B.The warm room can make students fall asleep easily.
C.Students'sleepiness has nothing to do with teaching.
D.The light level may lead students to feel sleepy.
66.If you wake up at six in the morning,when will you begin working ineffectively?A
A.At about 9pm         B.In the early morning.
C.At about noon.      D.In the midnight.
67.According to the passage,at 8:00am a teenager willB.
A.feel more energetic after a night's sleep
B.have a poor learning result
C.have the least desire to learn
D.be able to think in a quick way.

解答 DCAB
64  D  细节题. 根据文章第二 段The problem with waiting until the weekend to meet sleep needs is that in the meantime,you are paying the price of being less alert,feeling more moody,thinking slower and having less stimulation. 可知一个有睡眠债的学生会容易愤怒和伤心,故选D.

10.CThe iPhone,the iPad,each of Apple's products sounds cool and has become a fashion.Apple has cleverly taken advantage of the power of the letter"i"-and many other brands are following suit.The BBC's iPlayer-which allows Web users to watch TV programs on the Internet-adopted the title in 2008.A lovely bear-popular in the US and UK-that plays music and video is called"iTeddy".A slimmed down version of London's Independent newspaper was launched last week under the name"i".
In general,single-letter prefixes have been popular since the 1990s,when terms such as e-mail and e-commerce first came into use.
Most"i"products are targeted at young people and considering the major readers of Independent"i",it's no surprise that they've selected this fashionable name.
But it's hard to see what's so special about the letter"i".Why not use"a","b",or"c"?According to Tony Thorne,head of the Language Center at King's College,London,"i"works because its meaning has become ambiguous.When Apple uses"i",no one knows whether it means Internet,information,individual or interactive,Thorne told BBC Magazines."Even when Apple created the iPad,it seems it didn't have one clear definition."He says.
"However,thanks to Apple,the term is now associated with portability(轻便)."Adds Thorne.
Clearly the letter"i"also agrees with the idea that the Western World is centered on the individual.Each person believes they have their own needs,and they love personalized products for this reason.
Along with"Google"and"blog",readers of BBC Magazines voted"i"as one of the top 20 words that have come to define the last decade.
But as history shows,people grow tired of fashion.From the 1900s to 1990s,products with"2000"in their names became fashionable as the year was associated with all things advanced and modern.However,as we entered the new century,the trend disappeared.
61.People use iPlayer toD.

B.iTeddy is a live bear
C.the letter"b"replaces letter"i"to name the products

8.You are given many opportunities in life to choose to be a victim or creator.When you choose to be a victim,the world is a cold and difficult place."They"did things to you which caused all of your pain and suffering."They"are wrong and bad,and life is terrible as long as"they"are around.Or you may blame yourself for all your problems,thus internalizing(内化)your victimization.The truth is,your life is likely to stay that way as long as you feel a need to blame yourself or others.
Those who choose to be creators look at life quite differently.They know there are individuals who might like to control their lives,but they don't let this get in the way.They know they have their weaknesses,yet they don't blame themselves when they fail.Whatever happens,they have choice in the matter.They believe their dance with each sacred(神圣的)moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.
Victims and creators live in the same physical world and deal with many of the same physical realities,yet their experience of life is worlds apart.Victims relish (沉溺)in anger,guilt,and other emotions that cause others---and even themselves---to feel like victims,too.Creators consciously choose love,inspiration,and other qualities which inspire not only themselves,but all around them.Both victims and creators always have choice to determine the direction of their lives.
In reality,all of us play the victim or the creator at various points in our lives.One person,on losing a job or a special relationship,may feel as if it is the end of the world and sink into terrible suffering for months,years,or even a lifetime.Another with the same experience may choose to first experience the grief,then accept the loss and soon move on to be a powerful creative force in his life.
In every moment and every circumstance,you can choose to have fuller,richer life by setting a clear intention to transform the victim within,and by inviting into your life the powerful creator that you are.

15.Sir Steven Redgrave
Winner of 5 Olympic Gold Medals
"In 1997 I was found to have developed diabetes(糖尿病).Believing my career was over,I felt extremely low.Then one of the specialists said there was to no reason why I should stop training and competing.That was it-the encouragement I needed.I could still be a winner if I believed in myself.I am not saying that it isn't difficult sometimes.But I wanted to prove to myself that I wasn't finished yet.Nothing is to stand in my way."
Karen Pickering
Swimming World Champion
"I swim 4 hours a day,6 days a week.I manage that sort of workload by putting it on top of my diary.This is the key to success-you can't follow a career in any field without being well-organized.List what you believe you can achieve.Trust yourself,write down your goals for the day,however small they are,and you'll be a step closer to achieving them."
Kirsten Best
Poet & Writer
"When things are getting hard,a voice inside my head tells me that I can't achieve something.Then,there are other distractions,such as family or hobbies.The key is to concentrate.When I feel tense,it helps a lot to repeat words such as‘calm',‘peace'or‘focus',either out loud or silently in my mind.It makes me feel more in control and increases my confidence.This is a habit that can become second nature quite easily and is a powerful psychological(心理的) tool"

5.Youngsters who have no regular bedtime or who go to bed later than 21:00 have lower scores for reading and maths.Lack of sleep may influence how well the brain learns new information.
The findings on sleep patterns and brain power come from a UK study of more than 11,000 seven-year-olds.
Theygathered information on the children at the ages of three,five and seven to find out how well they were doing with their learning and whether that might be related to their sleeping habits.
Establishing (制定) a good bedtime routine early in childhood is important.Irregular bedtimes were most common at the age of three,when around one in five of the children went to bed at varying times.By the age of seven,more than half the children had a regular bedtime of between 19:30 and 20:30.
Children with irregular bedtimes tended to be less successful than their playmates in terms of test scores for reading,maths and spatial awareness(空间想象).The influence was more obvious throughout early childhood in girls than in boys and appeared to be increasing.
The researchers said it was possible that irregular bedtimes were a reflection of chaotic (无秩序的) family settings and they had an influence on cognitive (认知的) performance in children.The children with late and irregular bedtimes came from more socially disadvantaged backgrounds and were less likely to be read to each night and,generally,watched more TV.After controlling for such factors,the link between poorer mental performance and irregular bedtimes remained.
67.The text mainly deals with the relation between children'sD.
A.reading abilities and their sleeping habits
B.mental development and their sleeping habits
C.behaviour and their studying habits
D.performance in learning and their sleeping habits
68.The underlined word"They"in the third paragraph refers to"B"
A.the findings                     
B.the researchers
C.the seven-year-olds             
D.the sleep patterns             
69.Which of the following is TRUE according to the text?C
A.About one third of the three-year-olds go to bed at irregular bedtimes.
B.Irregular bedtimes were most common before the children were three months old.
C.More than half the children didn't have a regular bedtime until they were seven years old.
D.Teachers should help their kids establish a good bedtime routine early in childhood.
70.We can know from the text thatD.
A.boys with irregular bedtimes do worse in reading than their playmates
B.girls with regular bedtimes perform better in learning than boys
C.girls with irregular bedtimes do worse in reading than boys
D.the gap between girls with and without regular bedtimes is larger than that between boys.
12.About ten men in every hundred suffer from color blindness in some way.Women are luckier; only about one in two hundred is affected in this matter.Perhaps,after all,it is safer to be driven by a woman!
There are different forms of color blindness.In some cases a man may not be able to see deep red.He may think that red,orange and yellow are all shadows of green.Sometimes a person cannot tell the difference between blue and green.In rare cases an unlucky man may see everything in shades of green-a strange world indeed.
Color blindness in human beings is a strange thing to explain.In a single eye there are millions of very small things called"cones".These help us to see in a bright light and to tell difference between colors.There are also millions of"rods",but these are used for seeing when it is near dark.They show us shape but no color.
Some insects have favorite colors.Mosquitoes prefer blue to yellow.A red light will not attract insects,but a blue lamp will.In a similar way human beings also have favorite colors.Yet we are lucky.With the aid of the cones in our eyes we can see many beautiful colors by day,and with the aid of the rods we can see shapes at night.One day we may even learn more about the invisible colors around us.
51.The passage is mainly aboutD.
A.color and its surprising effects.
B.women being luckier than men
C.danger caused by color blindness  
D.color blindness
52.According to the passage,with the help of the"cones",we canD.
A.tell different shapes                   
B.see in a weak light
C.kill mosquitoes                      
D.tell orange from yellow
53.Why do some people say it is safer to be driven by women?B
A.Women are more careful.
B.There are fewer color-blind women
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking.
54.Which of the statements about the color-blind is true?A
A.Not all of them have the same problem in recognizing color.
B.None of them can see deep red.
C.None of them can tell the difference between blue and green.
D.All of them see everything in shades of green.
55.We can attract and kill mosquitoes by using aC.
A.red light     B.yellow light     C.blue light      D.green light.
9.Like human beings,dogs may catch cold because of cold weather,wet conditions or can also get it from other sick dogs.If a dog has a running nose and watery eyes,coughs or sneezes(打喷嚏),then it is quite probable that the dog has caught cold.
A dog's cold can get over after a few days without treatment but it totally depends upon the owner to treat it with medications or improve its immune power (免疫力) to get rid of the cold naturally.Following are some of the things you can do if your dog gets a cold.
You can improve its immune power by giving it proper nutrient diet.Healthy food can really do wonders.Try to give it food which is either suggested by the vet(兽医) or is healthy for your pet.Increase the intake of food which is rich in vitamins A,C and E.
Keep your dog warm.The best place for your dog in winter is inside your house.Do not keep your dog outside when it is cold and wet.At home you can also keep the dog warm with the help of carpets.This will make him comfortable and help him to recover fast.
Increase the fluid(流质)intake as it helps a lot.Water can be the best choice but you can also add broth (肉汤)in water which will give your dog strength.Warm water will make your dog more comfortable and will also keep the dog away from the respiratory infections(呼吸道感染).
Steam treatment is considered to be effective in getting rid of cold.It makes the nasal(鼻的) passage wet,which helps proper breathing.Just fill your bathroom with steam and leave your dog inside the bathroom for 15 minutes.Do it nearly 2 to 3 times a day and you will see your dog recovering.
These are some of the things you can do to help your dog recover from cold.However,if you are not able to find any improvement in its health,then turn to the vet for help immediately.Take your dog for regular checkups so as to avoid complications(并发症).
64.From the first paragraph we know aboutD.
A.the difficulty in keeping a dog as a pet   
B.characteristics of sick dogs
C.the similarities between dogs and human beings   
D.causes and symptoms(症状)of cold in dogs

A.its favorite food                      
B.the suggested food by the vet
C.some meat and water                   
D.food rich in vitamin B
66.When a dog catches cold,it is wrong toC.
A.keep it inside during cold and wet weather  
B.leave it inside the bathroom full of steam
C.let it eat too much solid food             
D.keep it sleeping on rugs at home
