19.If you see someone drowning,speed is very important.Once you get him out of the water,if he isn't breathing,you have four minutes before his brain is completely destroyed.Support his neck,tilt(使翘起)his head back and press his chin(下巴)upwards.This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again.If that doesn't work,start mouth-to-mouth breathing.Press his nostrils(鼻孔)together with your fingers.Open your mouth and take a deep breath.Blow into his lungs until his chest rises,then remove your mouth and watch his chest fall.Repeat twelve times a minute.Keep doing until help arrives.
To bring a child back to life,keep your lips around his mouth and nose and gently blow into his mouth.Give the first four breaths as quickly as possible to fill the blood with oxygen.If,in spite of your efforts,he starts turning a blue grey color,you can feel no pulse(脉搏),then pressing is the last chance of saving his life.
With arms straight,rock(摇动)forwards,pressing down on the lower half of the breastbone.Don't be too hard or you may break a rib(肋骨).Check how effective you are seeing if his color improves or his pulse becomes independent to your chest pressing.If this happens,stop the pressing.Otherwise continue until  rescue arrives.

7.Your smart-phone(智能手机) can do a lot of things.It can call people.It connects to the Internet.It enables you to play fun games.But there is a dark side to this smart little device of yours-it might also spread disease.
"People are just as likely to get sick from their phones as from handles of the bathroom,"Jeffery Cain,the president of the American Academy of Family Physicians,told The Wall Street Journal.
This may be hard to believe,but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago.All the tested phones showed high numbers of coli forms(大肠菌),a kind of bacteria found in excrement(粪便),with about 2,700 to 4,200 units of the bacteria on each phone.In drinking water,the healthy limit is less than 1 unit per 100 ml of water.This bacteria can cause flu,pinkeye(红眼病) and diarrhea(腹泻).That's right-your phone is covered with excrement!
Although computers,keys and pens all carry bacteria,our smart-phones get far dirtier.They touch a lot of stuff,including our pocket or purse.We take them almost everywhere:the bus,the subway and who hasn't played Angry Birds or Fruit Ninja while sitting on the toilet?
"Some things that we think are personal are actually more public than we imagine,"Cain said.
What's even worse is that after the phone returns from its dirty trip,it then spends most of its time covering our faces.Our noses,mouths and ears are all warm and rich in grease(油脂),an environment that bacteria really like.
Compared to traditional keypads,touch screens spread bacteria more easily to hands.According to Time magazine's website,an expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.

14.A team of US psychologists(心理学家) have found that talking to another person for ten minutes a day helps with memory.
"Socializing is just as effective as more traditional kinds of mental exercise in boosting memory and intellectual (智力的) performance,"Oscar Ybarra,a psychologist at the University of Michigan Institute for Social Research,said in a statement.
In one investigation,they analyzed data on 3610people,aged 24to 96.
They found that the higher their level of social interaction(交流),the better their cognitive (认知的)functioning.Social interaction includes getting together or having phone chats with relatives,freinds and neighbors.
In another experiment,the researchers conducted lab tests on 76college students,aged 18to 21,to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests.
The students were divided into three groups:the social interaction group had a discussion of a social issue for 10minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group(对照组)watched a 10-minute clip(电影片段)of the Seinfeld television show.
"We found that short-term social interaction lasting for just 10minutes improved participants'intellectual performance as much as engaging in so-called'intellectual'activities for the same amount of time,"Ybarra said.
The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin.

56.The underlined word"boosting"in the second paragraph can be replaced byA.
A.improving                 B.decreasing
C.preventing                D.training
57.Which is not included in social interaction?C
A.Having a talk with a neighbor.
B.Attending a birthday party.
C.Watching TV at home alone.
D.Calling your classmates
58.What's the purpose of the experiment on 76college students?A
A.To judge the effect of social interaction on memory and intelligence.
B.To find out what is real social interaction.
C.To learn how much time is needed for social interaction.
D.To show the function of people's cognition.
59.Which of the following questions may be asked in the social interaction group in the experiment?B
A.What does the author want to show us?
B.Do you like living in a big city or a small one?
C.Which word can be used to fill in the blank?
D.What is the main idea of the second paragraph?
60.What's the main idea of the passage?D
A.Intellectual exercises improve memory.
B.Different people have different ways of communication
C.Communicating with others keeps you healthy.

4.Learning the language of a country isn't enough.If you want to ensure a pleasant visit,find out as much as possible about the manners and customs of your hosts.
Sometimes good manners in one place are bad manners in other places.If you are a visitor in the land of Mongolia,some friends ask you to eat with them.What kind of manners do they want you to have?They want you to give a loud"burp"(打嗝) after you finish eating.Burping would show that you liked your food.But in some other countries,if you give a loud burp,you are told to say"Excuse me,please."
In many places,people like to eat together.But in some parts of Polynesia it is bad manners to be seen eating together.People show their good manners by turning their backs on others while they eat.
You will probably be surprised just how different they can be from your own.A visitor to India would do well to remember that people there consider it impolite to use the left hand for passing food at table.The left hand is supposed to be used for washing yourself.Also in India,you might see a man shaking his head at another to show that he doesn't agree.But in most parts of India,a shake of the head is a gesture that expresses agreement or acceptance.Nodding your head when you are offered a drink in Bulgaria is likely to leave you thirsty. In that country Bulgaria,you shake your head to mean"yes"-a nod means"no".
In Europe it is quite usual to cross your legs when you are sitting talking to someone,even at an important meeting.Doing this when you are meeting an important person in Thailand,however,could cause offence.It is considered too informal an attitude for such an occasion.Also try to avoid touching the head of an adult-it's just not done in Thailand.
Attitudes to women vary much around the world.In Japan,for example,it is quite usual for men to plan evening entertainments for themselves and leave their wives at home.
Knowing about customs and attitudes is useful when you are traveling,but you also need to know the language used to express different degrees of formality(礼节).
51.In Mongolia,if you give a loud burp after eating,your friends will be veryC.
A.surprised             B.sorry            C.happy               D.upset
52.Where do people eat back to back?A
A.In Polynesia          B.In Mongolia     C.In Japan             D.In India
53.From the passage,we know that shaking head means"yes"inD.
A.Thailand          B.Mongolia        C.Japan            D.Bulgaria
54.The underlined sentence"Nodding your head when you are offered a drink in Bulgaria is likely to leave you thirsty."MeansA.
A.you are probably not to be served a drink when you nod your head
B.you're possibly eager to have a drink if you nod your head
C.it's probable that you are thirsty if you nod your head
D.you'd like to have a cup of tea because you nod your head

11.All work and no play makes Jack a dull boy.That saying holds true not only for you and me,but also for some of the most powerful and influential people in the world,such as the presidents of the United States.
But how do American presidents spend their vacation time?Let's take a look!
Franklin D.Roosevelt,considered one of the greatest presidents in American history,had limited vacation options because of his polio(小儿麻痹症).He began visiting Warm Springs,Georgia in 1924 for its curative waters and later built a 2,000 acre polio treatment center nearby.He liked to cruise the Potomacon his yacht(游艇) and three times as president returned to his beloved Canadian island of Campobello,with which he fell in love as a kid.
Former President Bill Clinton,however,was never much good at vacationing.His staff had to practically force him to go on vacation his first year in office; his idea of relaxing was reading four good books simultaneously(同时) while enjoying a cigar (chewed,not smoked).He could also lose himself in a game of golf,where his somewhat flexible interpretation of the rules could at times drive his partners crazy.
Obama's predecessor(前任) also knows how to relax.Fishing is in the Bush family DNA:for blue sharks off the coast of Maine or anything with fins,almost anywhere else.George W.Bush also relaxed as president by jogging and clearing brush on his Texas ranch.Since leaving office,he has become an active mountain biker and,more recently,has taken up painting.
Obama tends to take a winter break in Hawaii,where he was born and raised,and a summer vacation in Martha's Vineyard,off the southern coast of Cape Cod,Massachusetts.In between,he plays basketball every couple of weeks and has been known to do some skeet shooting at Camp David.Obama's favorite pastime,no matter the location,has become easy to spot:golf.
