12.Turning the lights out or wearing a blindfold while eating could be a quick way to lose weight,according to scientists.The simple trick works because it stops diners eating for pleasure rather than for calories.It also triggers (引發(fā)) a part of the brain that is worried that unseen food may go bad.
An experiment by the University of Konstanz,in Germany,found that people who were blindfolded consumed nine percent fewer calories before they felt full,compared to those who could see.They also vastly overestimated how much they had eaten because they could not see how much was left on the plate.Blindfolded volunteers estimated they had eaten 88percent more than they actually had.
Scientists believe that not seeing food on the table also allows the body to know when it is full in real time rather than remembering past experiences where it might have taken a full plate to feel full.
In the experiment,50 people were blindfolded and 40were allowed to see their food.All were told not to eat within two hours of the experiment.They were then given three 95g bowls of chocolate ice cream and invited to eat for 15minutes.Their bowls were taken away and the remaining ice-cream weighed,while the participants were quizzed on how much they thought they had eaten.
On average the group who could see ate 116g while the blindfolded groups ate 105g.However,the blindfolded group believed they had eaten 197g while compared with 159g for the non-blind volunteers.They were also asked how pleasant the ice-cream tasted and the blindfolded group rated lower than those who could see.
"The experienced pleasure of eating was significantly lower in the blindfolded group.Not seeing the food might have decreased the appetite.Sight plays an important role in the eating experience and in the overall dining experience."
Previous studies have shown that the visual influence of food plays a large part in the taste.While restaurants that allow diners to eat in the dark state that it triggers other senses,in fact eating in darkness is likely to taste far milder than usual.
63.With the lights out,diners eat less partly becauseD.
A.they want to quickly finish their meals
B.they trust their feelings more than ever
C.they focus more on fun than the calories
D.they worry about the quality of the food
64.We can learn from the passage that the blindfolded groupB.
A.spent a much longer time eating the same food
B.believed they ate more than they really did
C.depended on past experiences to feel full
D.thought the food tasted better than usual
65.The last two paragraphs tell us thatA.
A.diners are likely to lose their appetite eating in darkness
B.senses rather than sight play an important role in the taste
C.findings of this experiment differ from the previous studies
D.restaurants benefit a lot from allowing diners to eat in the dark
66.The main purpose of the passage is toC.
A.provide statistics related to eating in the dark
B.offer reasons for people to eat in the dark areas
C.inform the readers of the result of an experiment
D.persuade the readers to lose weight in a new way.

20.JK Rowling,the Harry Potter author,has signed a deal with Little,Brown and Company,to publish her first ever novel for adults,which is set to become one of the most anticipated (期望的) book in years.
The deal means that Rowling's long-standing relationship with Bloomsbury,the London-based publisher that launched (發(fā)行) the Harry Potter books,has come to an end,at 1east in terms of new works by the author.
Rowling is keeping her fans guessing about the characters and plot of her new book.She only said that the new novel will be nothing like the Harry Potter series,which was sold over 30 million copies in the UK alone.She thought that with the move from children's to adult fiction,a switch to a new publisher seemed like a natural and reasonable step.
She said,"Although I've enjoyed writing it every bit as much,this book will be very different from the Harry Potter series.The freedom to explore a new field is a gift that Harry's success has brought me."
Ian Rankin,the Edinburgh-based author whose highly-successful detective novels are also set in the city,suggested Rowling's book will be a crime novel.
"Wouldn't it be funny if JK Rowling's first novel for adults turned out to be a crime story set in Edinburgh?"he said.
Industry insiders guessed that the deal is worth more than£5 million and the new book is expected to come out later this year.
A spokesman said,"JK Rowling's audience is vast and her position is unique.Harry Potter books were a global success and her fans are very loyal.Children that were eight,nine,or ten when the books first came out in the 1990s are now in their 20s.Plenty of adults,loved the books regardless of whether they had children,so the potential market for her is huge."

17.Goodbye to teeth
This all started a few months ago,when I had a dull pain in the back of my mouth,around where one of my wisdom teeth was supposed to be coming in.I thought it was a pain that I could live with for a while.
However,during the next few weeks,the pain became more intense,spreading to my teeth,gums and jaw.I was told I had seven wisdom teeth.
Yes,you read that correctly,seven-three more than a normal person.My first reaction when
I heard was to laugh.It's just my luck.My mouth wanted to do more work than it had to.
Focusing on the positive,one of the great things about having extra teeth is watching people's reactions when they find out.So far,I haven't grown tired of repeating myself.
The extra teeth are also a good excuse for me being tongue-tied.I can now blame it on my overcrowded mouth rather than my slow brain.
Of course,with wisdom teeth come the intellect jokes.My parents say my intelligence comes from my extra teeth and not my hard work.My friends agree that once the teeth are pulled,my brain will be that of a 5-year-old.
I've also thought about how I might profit from this.If only I still believed in the tooth fairy,I could make a lot of cash.Maybe I could sell my extras to someone in need.Advertisement:Seven teeth for sale,unused,in almost perfect condition.
Don't be fooled by my jokes.I am worried about having surgery.I'm also going to be sad to see the Lucky Seven go.I've developed quite an attachment to them over the past two days.Once they're removed,I'll just be normal again,and who wants that?

24.When the author found that she had three more wisdom teeth than a normal person,sheA.
A.found it quite funny
B.dealt with the pain calmly
C.was confused and anxious
D.kept it secret from others
25.The intellect jokes from the author's family and friends were intended toC.
A.persuade the author not to remove her wisdom teeth
B.a(chǎn)dvise the author to work hard to improve her intelligence
C.make fun of the author in a light-hearted way
D.let the author know why she is often tongue-tied
26.When the author came up with the idea of tooth fairy,sheD.
A.believed that her wisdom teeth would grow back
B.thought she could rely on it to make a living
C.had already made up her mind to make money
D.was deeply aware that the idea couldn't become reality
27.What's the article mainly about?B
A.People's different reactions to the author's wisdom teeth
B.How the author has gotten on with her extra wisdom teeth
C.The author's ideas for making use of her wisdom teeth
D.How the author has decided to remove her wisdom teeth.

4.All people need to sleep.Sleep is a restorative (恢復(fù)體力的) process that promotes proper body functioning and can improve the quality of your life.Not only is the quantity of sleep important,but also the quality of sleep.
Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment.One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep.If your bedroom also functions as a command station for your life and work,the likelihood of your sleeping being poor is rather high.Bedrooms should be designed,decorated and used for sleep mainly.TVs,computers and other things should not be in your bedroom at all if possible.
Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness.Avoid hot food,caffeine,sugar and alcohol at least 4to 6hours before your sleep time.Develop a regular exercise program.Proper exercise and nutrition will help improve sleeping patterns.However,avoid exercising 2hours before sleeping,since this may stimulate your body and make sleeping more difficult.
Establish a pre-bedtime rule that will help focus you on sleep.You can try meditation(沉思),reading or deep breathing and relaxation.Your bedtime rule should be yours.Do not worry about it fitting into a specific category.Do what is the best for you.
Things such as room temperature,noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience.Block out distracting noises and lights.You are in your bedroom to sleep and not be distracted by environmental interferences(干擾).

28.It can be inferred from the passage thatC.
A.bedrooms should be used for more activities

17.What is the single largest cause of sick leave in the UK?The answer is not the common cold or flu,but back pain.Back pain affects one in three British adults,costs the country over 5billion pounds every year and is very difficult to treat.But now Britain's National Health Service(NHS)will be offering a new solution:acupuncture.The ancient Chinese needle therapy(療法)has been around in the UK for many years,but this is the first time it has been officially approved by the NHS's advisory body,the National Institute for Clinical Excellence(NICE).
Traditionally,doctors in the UK have advised back pain sufferers to stay active,do stretching exercises and take painkillers when necessary and in more serious cases some people are given X-ray treatment or injections with therapeutic substances.
NICE,however,say there is evidence that acupuncture may be more effective than expensive X-rays or injections,so patients who have been suffering for over six weeks should be given a choice.As an alternative to acupuncture,patients will be able to choose for either a course of spinal manipulation(脊柱推拿術(shù)),or a series of special exercise sessions.In the UK,acupuncture is classed as a complementary therapy,which is the term given to a medical procedure which hasn't received the strict trials by which scientists prove some treatments work.
While many experts have welcomed the move to make acupuncture available on the NHS,some are still doubtful about its effectiveness.Research from the US earlier this month found that using toothpicks could be as good as using real needles.So while some are yet to be convinced,back pain sufferers will be hoping that acupuncture helps get them feeling healthy and mobile again.Employers,on the other hand,will be hoping it gets them back to work.

32.What can we learn from the first paragraph?B
A.The British have come to know acupuncture recently.
B.About thirty percent of the British suffer from back pain.
C.NICE has been arguing against Chinese needle therapy.
D.The British ask for sick leave mostly because of cold or flu.
33.The traditional ways to treat back pain in the UK includeC.
A.staying in bed for rest    
B.Chinese needle therapy
C.receiving X-ray treatment 
D.a(chǎn)voiding physical exercises
34.In treating back pain,acupunctureA.
A.may cost less than X-rays    
B.works surely better than injections
C.has gone through strict scientific tests 
D.will replace the traditional ways in the UK
35.What do experts think of acupuncture?D
A.They think highly of it.    
B.Most of them are against it.
C.Few recognize its usefulness.
D.They differ on its effectiveness.
