3．March 21 has been declared World Sleep Day，a time to recognize and celebrate the value of sleep．Many sleep experts hope it will be a wake-up call．
Cdording to a 2013poll （民意調(diào)查）by the National Sleep Foundation，nearly 4in 5Americans don't get as much sleep as they should during the workweek．On average，adults are thought to need at least eight hours of sleep a night，although some can manage with less and some won't do well without more．But the survey found that，on workdays，only 21% of Americans actually get a full eight hours of sleep，and another 21% get less than six．
To many of us，the thought of spending more time sleeping is，well，a big yawn．On the other hand，the thought of being smarter，thinner，healthier and more cheerful has a certain appeal．And those are just a few of the advantages that can be ours if we consistently get enough sleep，researchers say．Also on the plus side：We're likely to have better skin，better memories，better judgment，and，oh，yes，longer lives．
"When you lose even one hour of sleep for any reason，it influences your performance the next day，"says Dr．Alon Avidan，director of the UCLA Sleep Disorders Center．
A study published last year found the same to be true even of children．When kids aged 8to 12slept for just one hour less for four nights，they didn't function as well during the day．
But sleeping has an image problem．"We see napping or sleeping as lazy，"says Jennifer Vriend，a clinical psychologist in Ottawa，Canada，and the leading author of the study with children．"We put so much emphasis on diet，nutrition and exercise．Sleep is in the back seat．"In fact，she adds，no matter how much we work out，no matter how well we eat，we can't be in top physical shape unless we also get plenty of sleep．

31．The underlined part in Paragraph 1 meansC．
A．To wake up the sleepers
B．To serve as a morning call
C．To draw people's attention
D．To declare the special day
32．Which of the following is True according to Paragraph 2B？
A．People can do well without enough sleep．
B．Adults need at least eight hours'sleep a day．
C．Only one-forth of Americans have enough sleep．
D．One-fifth of American adults sleep less than children．．
33．From Paragraph 3 we can infer thatC
A．Being healthier is one of the advantages for us
B．Sleeping has nothing to do with one's expectations 
C．Enough sleep is the guarantee of the appealing things
D．Spending more time on sleeping is a waste of time
34．What Jennifer Vriend said in the last paragraph implies thatA
A．People care little about sleeping
B．Sleeping is an image problem
C．Lazy people tend to sleep long
D．Sleeping is only part of our life
35．What is the purpose of the passageD？
A．To talk about people's sleeping problems．
B．To provide an investigation result of sleeping．
C．To stress the function of sleeping at night．
D．To arouse the awareness of enough sleeping．

10．In spite of being used by 1.34 billion people each year，traveling on the Tube（地鐵） in London can actually be quite lonely．An unwritten rule encouraging silence，mixed with classic British reserved（矜持的）character，means that even though you're crowded into a limited space with hundreds of other people，you may still feel a bit lonely．
One London citizen，however，is trying to change this．
"You get on the Tube here and it's completely silent and it's strange，"says Jonathan Dunne，an American living in London，who has started a worldwide dialogue after giving out badges（徽章） with the slogan"Tube chat？"last month，encouraging passengers in London to get talking to one another．
"I handed out 500badges during rush hour in a city of 8million，expecting most of them to be thrown away，but after about 24hours it completely snowballed．"he says．
Although Dunne says he's received mostly positive response（反應(yīng)），not everyone agrees with his idea．
Londoner Brian Wilson responded with a movement of his own，handing out 500badges with the words"Don't even think about it"on them．
"I can't stand the idea of talking to strangers on the Tube on my way to work．"he told the BBC．
Michael Robinson，24，a student from London，agrees．"Being on the Tube is the only peace and quiet that some people get on their journeys to and from work．It doesn't need to be spoiled by people coming up and chatting to you．"he says．
"People think that I just walk up and talk to strangers，which I don't，but it's been a great way to meet people who you would never have normally spoken to．"Jonathan Dunne says．"On Monday[Oct 10]，the leader of the London Transport Museum had me over for tea．"
So if you ever end up using public transport in the West，why not say hello to the person next to you？Just make sure to check for a badge first．

32．The movement started by Jonathan Dunne aims toA．
A．change the cold atmosphere on the tube in London
B．change the"silent and cold"character of Londoners
C．make passengers change the unwritten rules of the tube in London
D．give passengers on the tube in London more chances to make friends
33．According to the passage，who might support the"Tube Chat"movement？D
①．Brian Wilson②．Jonathan Dunne
③．Michael Robinson④．The leader of the London Transport Museum
A．①②
B．②③
C．①④
D．②④
34．Which of the following might be the author's attitude toward Dunne's movement？B
A．Doubtful
B．Supportive
C．Objective
D．Uninterested
35．What is the main purpose of this passage？C
A．To say no to the coldness on the tube in London．
B．To show people's response to Dunne's movement．
C．To explain Jonathan Dunne's movement to readers．
D．To show the differences in public transport in Western culture．

15．When you cut your skin，you bleed （流血）．If a person loses a lot of blood，he will become ill and may die．Blood is very important．People have always known that．At one time，some people even drank blood to make them strong!
     When doctors understand how blood goes around inside the body，they try ways of giving blood to people who need it．They take blood from the healthy people and give it to people who need it．This is called"blood transfusion"．The blood goes from the arm of the healthy person into the arm of the sick person．
     But there are two problems．First，it does not always work．Sometimes people die when they have blood transfusion．Later，doctors find that we do not all have the same kind of blood．There are four groups-O，A，B and AB．We all have blood of one of these groups．They also find that they can give any kind of blood to people of group AB．But they find that they must give A-group blood to A-group people and B-group blood to B-group people．I have O-group blood and the doctor told me that I could give blood to anyone else safely．
     There is another problem．To give blood of the right kind，doctors have to find a person of the right blood group．Often they can not find a person in time．If they have a way to keep the blood until someone'needs it，they can always have the right kind of blood．At first they find they can keep it in bottles for fifteen to twenty days．They do this by making it very cold．Then they find how to keep it longer．In the end they find a way of keeping blood for a very long time．
     We call a place where we keep money a"bank"．We call a place where we keep blood a"blood bank"．One day，when you grow up，you may decide to give blood to a"blood bank"．In this way you may stop someone from dying．Or perhaps one day you may become ill．You may need blood．The"blood bank"will give it to you．
21．From the passage，we learn that sometimes people die when they have blood transfusion because theyC．
A．a(chǎn)re unhealthy people                  
B．have lost a lot of blood
C．a(chǎn)re not given the right kind of blood     
D．a(chǎn)re AB-group people
22．Which of the following is true？B
A．Doctors can give any kind of blood to the writer．
B．The writer can give blood to B-group people．
C．The writer has never had a blood transfusion．
D．The writer has the same kind of blood as his father．
23．People set up the"blood bank"so that they canA．
A．give the right kind of blood to the people who need it in time
B．keep different groups of blood as much as possible
C．make it easier to sell or buy blood
D．keep blood for more than twenty hundred years
24．From the last paragraph （段落） of the passage，we learn thatA．
A．the writer thinks it's good to give blood to a"blood bank"
B．we may become ill if we give blood to a"blood bank"
C．many people died because they lost a lot of blood
D．blood is more important than money．

12．There have always been a lot of commonly believed but false ideas about being fat and doing exercise．Some people believe that they can't help putting on weight as they get older，while others hold that if they stop exercising，their muscles will turn into fat．Here are some more myths：
I'll never lose weight---I come from a fat family
Wrong!While we can't change the body type we are born with，we can't blame（責備）our genes for making us fat．There's plenty of ev idence that fatness runs in families，and the main reason is that they share the same habits of eating too much and exercise too little．
I am fat because I burn calories slowly
Wrong!Fatness is not caused by a slow metabolism（新陳代謝）．If fact，although fat people consume（消耗）more energy that slim people，they also fail to realize how much they eat!Keeping a diary can help you work out your daily food intake（攝入） more accurately．
Exercise is boring
Wrong!Anything will become boring if you do it repetitively（重復(fù)地）．The key is to develop a balanced and varied program that's fun as well as progressive．If you enjoy a Sunday walk，take a different route．If you do Yoga，try a tai chi class．If you like swimming，set yourself a distance or time challenge．
No pain，no gain
Wrong!Exercise is not meant to hurt．Indeed，pain is your body telling you something's wrong，and continuing to exercise could lead to serious injury．You may experience mild discomfort as you begin to exercise regularly，but this is your body adapting to（適應(yīng)）the positive changes in your lifestyle and the aches should disappear relatively quickly．If you don't，rest and seek medical advice．
24．What does the author think about being fat？D
A．It is the family genes that make people fat．
B．People are fat because they consume too little energy．
C．A diary of exercise can prevent people from be coming fat．
D．It is the consequence（后果）of people's unbalanced lifestyle．
25．According to the author，how can we make exercise mom interesting？A
