3.Advice to"sleep on it"could be well founded,scientists say.After a good night's sleep a problem that seemed impossible to solve the night before can often appear easier,although no evidence has proved this by now.But researchers at the University of Luebek in Germany have designed an experiment that shows a good night's sleep can improve insight(洞察力)and problem-solving."If you have some newly acquired memories in your brain,sleep acts on these memories,restructures(重構(gòu))them,so that after sleep the insight into a problem which you could not solve before increases,"said Dr.Jan Bom,a neuroscientist,at the university.To test the theory,they taught volunteers two simple rules to help them put a string of numbers into a new order.There was also a third,hidden rule,which could help them increase their speed in solving the problem.The researchers divided the volunteers into two groups,half were allowed to sleep after the training while the remainders were forced to stay awake.Bom and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group."Sleep helped,"Bom said in a telephone interview."The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep,so it can act on the problem."But Bom admitted that he and his team don't know how restructuring of memories occurs or what governs it or in which stage of sleep it works.Pierre Marquette and Pierre Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can promote creative thinking.Although the role of sleep in human creativity will still be a mystery,the research gives people good reason to fully respect their periods of sleep,they added.

3.What is so amazing about giving blood?
The National Blood Service,which covers all of England and North Wales,needs nearly two and a half million blood donations each year.When you give blood,you'll be doing one of the most amazing things anybody could dream of-saving a life.
                                
All types of blood are needed-not just rare ones.In fact,the commoner the blood type,the more are needed.So even if your blood is one of the most common types-group O for example-you can be sure that by donating three times a year,you really are doing something amazing.
What is the donation process?
The donation will last about an hour in all.When you arrive,you will be asked a few questions about your health.Then a drop of blood will be taken and tested just to make sure you're not anemic(貧血).If all is well,your donation will be taken.
This only takes about ten minutes,during which time 470ml of blood will be collected.Most people hardly feel a thing.After a short rest,a drink and biscuits,you'll be up and ready to go.All equipment used in the collection of your blood is new and is never reused,so you don't have to worry about risks to your health in the collection of your blood.
Who can become a blood donor?
Becoming a blood donor really is very simple.As long as you're in good health and aged between 17and 60,you can become a blood donor.If you would like more information or advice,or you want to become a blood donor,ring the donor helpline on 0845 7711.The donor helpline is open 24hours a day-every day of the year.

1.It is a live celebration of the lasting power of letter writing!
Letters Live,which started in December 2013,was held at the Freemasons'Hall in London from March 10to 15.The show invited various great performers who read remarkable letters that had been written around the world over the centuries.
"Bringing letters alive through outstanding performances is one of the most powerful ways in which the joy and pain and humor and tragedy of being human can be shared,"Jamie Byng,managing director of Canongate Books publishing firm,told the Nowness video channel.
British actor Benedict Cumberbatch agreed."Letters are windows into the love,beauty,pain and humor of their creators and receivers,"he told The Guardian."Letters Live makes us stop and imagine the lives behind the letters read and where they came from.It's a privilege to read this most ancient of communications 1ive to an audience."
This year,the movie Sherlock star treated the audience by playing the part of a 17-year Tom Hanks.He put on the young actor's voice when he read his letter to the Hollywood director George Roy Hill,a letter that urged Hill to"discover"him.The letter revealed that two-time Oscar winner Hanks'teenage dream was not to"be a big-time Hollywood superstar"but to one day own a Porsche ear and call his favorite US actor Robert Redford his nickname"Bob"
Other famous faces at the event included Carey Mulligan,who played a fictional laundry worker,a female activist fighting for women's rights in the 2015movie Suffragette.The British actress once again played the role of a suffragette,when she read a very enthusiastic letter demanding the vote for women.The suffragette sent a precious 1913note to the Daily Telegraph newspaper.
"Everyone seems to agree upon the necessity of putting a stop to Suffragist anger,but no one seems certain how to do so,"Mulligan read out."There ape two,and only two,ways in which this can be done. Both will be effectual.One,kill every woman in the UK. Two,give women the vote."

28.What was Cumberbatch's attitude towards Jamie Byng's opinion?B
A.Doubtful    B.Positive.   
C.Optimistic.D.Cautious.
29.Which of the following was a dream of Tom Hanks as a child?D

12.Our world is a noisy place,but quiet places remain.Eight years ago,audio (聲音的) engineer Gordon Hempton identified the quietest place in the continental United States.He calls the place"One Square Inch of Silence."He has used his symbolic spot in a northwestern rain forest to campaign against noise pollution.But the self-described"Sound Tracker"is now going deaf.
    For Gordon Hempton,it started with an experience known to many people."I was lying in the bed in the springtime about a year ago.The sun was shining.The birds could be singing.They should be singing.But I was hearing none.I knew my life was going to be different."
    Hempton's eyes get watery as he describes his cruel situation.More than 20 years ago he trademarked his nickname as"The Sound Tracker."Sharp hearing defined his career as an Emmy award winning sound recordist.It also led to his activism against noise pollution.He has circled the globe three times in search of the perfect sounds of nature.
    Hempton says his hearing loss is quickly getting worse but he has to finish his project.
"I am running a race to finish the Quiet Planet collection."That's the title of a planned 19-volume set of nature recordings.The sound tracks could be licensed for use in movies,video games,exhibits,plays and the like.Volunteer assistants now help Hempton review and edit sound files and identify imperfections.
    The exact cause of his hearing loss is not clear.Doctors say it may be the result of an infection,or a tumor (腫瘤) or a combination of things.Hempton is self-employed.His health care plan does not pay for hearing loss treatment.So,for now,he's directing his attention to completing his"greatest hits"album."After I get it finished,I have an economic cash flow to get my hearing back.That's the first thing on my to-do list."He's hopeful his hearing loss can be recovered.
61.What do we know about Gordon Hempton according to the text?C
A.He never won an Emmy award
B.He fights against air pollution.
C.He works as an audio engineer
D.He likes living in the United States.
62.How did Gordon Hempton feel when he knew his ears were going deaf?D

B.Inspired
C.Annoyed
D.Sad.
63.What contributed most to his successful career?A
A.His sharp hearing
B.His reliable assistants.
C.Travelling experiences
D.The sounds of nature.
64.What is Gordon Hempton doing now?D
A.Listening to the birds in the forest
B.Receiving medical care in the hospital.
C.Doing activities for noise pollution
D.Working on the Quiet Planet collection.
65.What may be the best title of the text?B
A.Searching for the sound of nature
B.Successful Sound-Tracker going deaf.
C.Deaf fighter against noise pollution
D.Hoping to get the hearing back.
