16.Teenagers are damaging their health by not getting enough sleep because they are distracted(分散)by electronic products in their bedrooms,according to a survey.
UK advice body The Sleep Council said"junk sleep"could rival(比得上)the consumption of unhealthy junk food as a major lifestyle issue for parents of teenage children.It brings no less harm than junk food to one's health.Its survey of 1,000 teenagers aged 12 to 16 found that 30 percent managed just 4 to 7 hours sleep as opposed to(形成對照)the recommended 8 or 9 hours by the experts.Almost a quarter said they fell asleep more than once a week while watching TV,listening to music or using other electronic products.
"This is an extremely worrying situation",said Dr.Chris Idzikowski of the Edinburgh Sleep Centre."What we are seeing is the appearance of Junk Sleep-that is sleep which is of neither the length nor quality  that  it should be in order to feed the brain with the rest it needs to perform properly at school."
Nearly all the teenagers had a phone,music system or TV in their bedroom,with around two-thirds possessing all three.Almost one in five of the teenage boys said the quality of their sleep had been impacted by leaving their TV or computer on.The survey also found that 40 percent of teenagers felt tired each day,with girls aged 15 to 16 doing the worst.However just 11 percent said they were bothered by the lack or quality of sleep.
"I'm surprised that so few teenagers make the link between getting enough good quality sleep and how they feel during the day,"Idzikowski said."Teenagers need to wake up to the fact to feel well,perform well and look well; they need to do something about their sleep."

71.According to the experts,teenagers should sleepB every night.
A.4 to 7 hours      B.8 or 9 hours         C.6 or 7 hours         D.7 or 8 hours
72.Which of the following is NOT true about"junk sleep"?D
A.It's a kind of sleep with poor quality.
B.It's a kind of sleep with shorter hours.
C.It's mainly caused by the electronic products in the bedroom.
D.It's not as harmful as junk food to one's health.
73.The underlined word"impacted"in Paragraph 4 can probably be replaced by"C".
A.improved         B.destroyed            C.a(chǎn)ffected          D.inspired
74.It can be inferred from the passage that Dr.Chris Idzikowski is veryAabout the present situation.
A.worried            B.satisfied            C.a(chǎn)ngry           D.disappointed
75.What should be the best title for this passage?C
A.Junk Food and Junk Sleep
B.A Survey about Junk Sleep
C.Junk Sleep Is Damaging Teenagers'Health
D.How to Avoid Junk Sleep.

分析 這篇短文中作者主要講述了英國青少年的睡眠質量受到電子產(chǎn)品的危害,通過對青少年的睡眠調(diào)查得出很多數(shù)據(jù)并為此提出了擔憂.

解答 71.B.細節(jié)理解題.根據(jù)第二段Its survey of 1,000 teenagers aged 12 to 16 found that 30 percent managed just 4 to 7 hours sleep as opposed to(形成對照)the recommended 8 or 9 hours by the experts可知青少年應該睡覺每天8到9小時;故選B.
72.D.細節(jié)理解題.根據(jù)第二段It brings no less harm than junk food to one's health可知垃圾睡眠和垃圾食品一樣對健康有害;故選D.
73.C.詞義猜測題.根據(jù)文章Almost one in five of the teenage boys said the quality of their sleep had been impacted by leaving their TV or computer on可知幾乎五分之一的青少年表示,他們的睡眠質量已經(jīng)離開他們的電視或計算機的影響;意為影響;故選C.
74.A.推理判斷題.根據(jù)文章"I'm surprised that so few teenagers make the link between getting enough good quality sleep and how they feel during the day,"Idzikowski said可知Chris Idzikowski博士對青少年睡眠現(xiàn)狀很擔憂;故選A.

7.I was driving home the other day on a sunny afternoon.I had a smile on my face as I sang along to the songs on the radio.It was a beautiful day that I felt full of happiness.My good mood ended,however,when the radio station took a news break between songs.Then suddenly I found myself listening to yet another story of a rich famous man who had broken the law.I shook my head as I came to a red traffic light.
As I pulled to a stop I noticed four leather-jacketed bikers.They were standing in the middle of the road with two on either side of the light.They looked rough and dangerous,but as I got closer I noticed each one was holding their helmet in their hands.I rolled down my window as one approached my car."We are the Brother's of the Wheel",he said."We are collecting money for a Christmas Toy Drive for needy children."As I pulled a dollar out of my wallet I looked past his beard and tattoos and into his eyes.They shined with a goodness and kindness that came right from his soul.I dropped the money in his helmet and waved to the other bikers as I drove off.My good mood had returned.My faith in mankind had been bolstered.And I had to remember again never to judge people by their appearance.
Our society often judges books by their covers but God reads what is written in our hearts and souls.Perhaps one day we will all learn to see the world through the same eyes.Perhaps one day we will realize that looks matter little and actions matter much.

21.The writer's good mood ended whenA.
A.he hear news between songs
B.he had to stop at a red traffic light
C.he heard a rich man broke the law
D.he saw four leather-jacketed kids in need
22.What are four bikers doing at the traffic light?C
A.Having a bicycle race in the street
B.Selling helmets to the passers-by.
C.Raising money to help kids in need
D.Preparing for Christmas holidays.
23.What does"bolstered"in the second paragraph probably mean?B
A.Destroyed.B.Improved.C.Decreased.D.Exploded.
24.The writer to tell us that we shouldB.
A.have faith in young people
B.judge others by their actions
C.change our attitude to society
D.manage to help others in need.

5.閱讀下面短文,根據(jù)其內(nèi)容寫一篇60詞左右的內(nèi)容概要.
What should doctors say,for example,to a 46-year-old man coming in for a routine physical checkup just before going on vacation with his family who,though he feels in perfect health,is found to have a form of cancer that will cause him to die within six months?Is it best to tell him the truth?If he asks,should doctors reject that he is ill,or minimize the gravity of the illness?Should they at least hide the truth until after the family vacation?
Doctors face such choices often.At times,they see important reasons to lie for the patients'own sake.Should doctors ever lie to benefit their patients---to speed recovery or to cover the coming of death?
Studies show that most doctors sincerely believe that the seriously ill patients do not want to know the truth about their condition,and that informing them of risks destroys their hope,so that they may recover more slowly,or deteriorate(惡化)faster,perhaps even commit suicide.
But other studies show that,contrary to the belief of many physicians,a great majority of patients do want to be told the truth,even about serious illness,and feel cheated when they learn that they have been misled.We are also learning that truthful information,humanely conveyed,helps patients cope with illness:help them tolerate pain better,need less medicine,and even recover faster after surgery.
Not only in medicine,but in other professions such as law and government as well,practitioners(從業(yè)者)may find themselves repeatedly in the dilemma of choosing between telling the true information and covering it up.Therefore,there is an urgent need to debate this issue openly.Otherwise,people in our society will be blindly comfortable in the old saying,"What you don't know can't hurt you."
Should a doctor lie to patients for their benefit?According to some studies,to avoid the risk of worsening their health condition,most doctors choose to hide the truth from the patient suffering from fatal illness.However,it has been found out most patients prefer to be told the truth,which,if imparted,will enable them to battle bravely with illness.In view of the similar dilemma repeated in other professions,this issue cries for an open debate..

6.When enjoying children's birthdays or a long-expected family holiday,you may usually want to keep those important moments in mind with a photograph.But if you're one of those people who can't stop snapping photos at an important event,be aware--you could end up forgetting it all in a flash.
Experts have warned that the addiction to recording every moment of our lives could be having an adverse effect on our memories.
Maryanne Garry,a New Zealand psychology professor,has been studying how the frequent taking of photos might change childhood memories.44I think the problem is that people are forgetting to experience the moment,she says.Parents at the park taking one photo after another of their children,for example,are actually paying less attention to what is happening around them.The picture only captures a small part of the total experience.And because parents remember less about these important events,they become less effective in their role as the key people who help children learn how to talk about their experiences.As a result,children's own childhood memories are reduced.
The idea that we are experiencing less as we record more got psychologist Linda Henkel's thinking.She wanted to explore how photographs shape our memories.
Henkel,who researches human memory at Fairfield University in Connecticut,did an experiment by sending groups of students to the university's art museum.The students observed some objects and photographed others.Then,back at the laboratory,they were given a memory test.Henkel found what she called a"photo-taking effect".The students remembered fewer of the objects that they had taken photos of,and they remembered fewer details about those objects.She says her students'memories were worse because they were relying on the camera to remember the details for them.
"As soon as you hit‘click'on that camera,it's as if you've decreased your memory."she says.

32.What does the word"it"in Paragraph 1 refer to?B
A.A child's birthday.
B.An important event.
C.A valuable photograph.
D.A family holiday.
33.How did Henkel develop her theory about the"photo-taking effect"?A
A.By carrying out an experiment.
B.By giving a questionnaire.
C.By interviewing a group of students.
D.By researching the findings of the others.
34.According to Paragraph 3,why are children's memories reduced?D
A.Flash lights are causing children to forget more things.
B.Parents are into listening to children's experiences.
C.Children are more into taking photos than experiencing.
D.Parents are less effective in helping children discuss their experiences.
35.What's the purpose of this passage?B
A.To introduce a new discovery in taking photos.
B.To discuss the effect of photo-taking on memory.
C.To explain how to use cameras in an effective way.
D.To describe the ways of remembering valuable experiences.
