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

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?

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.
D.Social interaction makes you smart.

5.How would you like to brush a crocodile's teeth?Or give a shark a bath?Cats are well-known for the way they keep themselves clean by licking(舔),but other animals have their own ways to stay clean as well.And tidiness can be important for their survival.Even cockroaches(蟑螂)have to keep their feelers clean to help them into food.
    Many animals in the wild,such as deer,wolves and bears,have an automatic cleaning system.Insects like to attach themselves to animals to feed on the skin or blood.These parasites(寄生虫) can be unhealthy.But their"host"animals are constantly dropping skin and fur by a natural process.They also like to rub up against trees or rocks to comfort themselves,and this removes additional skin and fur.Along with old fur goes the dirt and parasites living in the fur.While these animals may sometimes take a bath when they enter or cross a river or lake,they don't need the water to stay clean.They don't get sweaty,because they don't have sweat glands(汗腺)all over their bodies the way people do.Growing new skin and fur is enough to keep them clean.
    Some animals and birds use dust to get clean.Chinchillas,a kind of small animal that lives in
the mountains of South America,have a very fine fur.(They are raised for their fur,in fact.)If they took water baths,they might get too cold.So,instead,they roll around in fine dust,raising
quite a cloud as they"bathe".The dust helps to keep their fur and skin dry.This protects them
from bacteria and parasites that enjoy warm and wet places.And the fine dust doesn't stick in their
fur for long.It falls off or blows away.
    As for lions and tigers.their rough tongues act like combs and can remove dirt and loose fur.
Why is it important for them to stay clean and smooth?It helps them stay cool in very hot summer or feel warm in cold winter.
55.What's the main idea of this passage?A
  A.For animals,cleanliness is a survival skill.
    B.Animals enjoy living in a clean environment.
    C.Unlike people,animals hate staying in water.
    D.Animals fight against parasites in different ways.
56.According to the passage,such animals as deer,wolves and bears clean themselves byB   
    A.living with parasites
    B.replacing their skin and fur naturally
    C.climbing trees or rocks
    D.having a bath in a river or lake
57.It can be inferred from the passage that the way some animals stay cleanA    A.is decided by their physical conditions
    B.is better than the way people do
    C.keeps them away from parasites all the time
    D.helps them survive any danger in the wild.

2.When you get tense(紧张的) about something that happens in your life,you are experiencing stress.Too much stress can cause anger,depression and other related symptoms,which you need to seriously look into.
The following are simple ways that can be used to deal with stress.
Be Gentle with Yourself
There are times when you are not fair to yourself.Often you are harder on yourself than you are of other people.If you can learn to accept yourself just the way you are,especially unconditionally,this would reduce the pressure you apply to yourself.
Exercise
Go for a walk.Go to the shops.You can join a local walk,swim or jog team.If you are tired out from doing housework and haven′t left your workstation,have a stretch.Change your environment for an hour or so.
Stop Comparing Yourself with Others
Often you don′t realize that a great deal of unhappiness is caused by constant comparisons you make.You says,"if only I had a big house like she was…","if only my husband were as rich as hers…"The comparison is endless.The only comparison that counts is the comparison between where you were and where you are now.By all means,admire others,congratulate them and be proud of their achievements,but remind yourself that only you can decide the standard(标准) you want to set for yourself.
Talk the Stress Out
Sometimes it helps to share or talk about your stress to close friends or family members.The other person′s active listening can help.

25.The passage is mainly aboutB.

9.There's no place in the world like Venice,Italy.Called the City of Water,Venice was built about 1,500 years ago.It's made up of 118 tiny islands in the Adriatic Sea.The area,however,may be in over its head.But now scientists have a new plan to save the city.
Because the city was built on soft soil,it has been sinking under the pressure of its own weight.Scientists estimate that Venice sinks at a rate of nearly 2 inches every 100 years.Rising sea levels could make Venice go under even faster,some experts say.Earth's temperature is slowly increasing.That is causing sea ice to melt,which makes the world's waters rise,they say.
To keep the city afloat,experts want to pump about 40 billion gallons of sea water beneath Venice.The liquid would expand the sand under the city,which would help support the islands,explains lead scientist Giuseppe Gambolati.
Experts are rushing to save Venice because of its rich history.The city was once a strong sea power."Many famous artists and opera singers have come from Venice.Some of the world's greatest paintings can be found on the city's museum walls,"explains Melissa Conn,who is a director of Save Venice Inc.
While scientists work to get their water-pumping plan approved,Venice's residents go about their normal routines.When the tide rolls in,the locals have ways of keeping everyone dry.Cafe owners move tables to higher ground,and hotels pass out high boots to guests.
Still,dealing with the rising water does not give the city's residents a sinking feeling,just ask Erla Zwingle.She has lived in Venice for 17 years."There has always been high water in Venice."Zwingle told WR News."If high water really were a serious problem,people wouldn't be still living here."
56.What's the main reason Venice is sinking?C
A.Its population is rising.
B.Its buildings are too weighty.
C.The soil it was built on is not solid.
D.Its underground water is being overused.
57.What can we know about Venice from the passage?D
A.It sinks at a rate of 2 inches every 200 years.

C.It has been in a very dangerous situation.
D.It was once a strong sea power.
58.According to Melissa Conn,VeniceB.
A.is not protecting properly  
B.deserves the world's attention
C.is best-known only for its artists  
D.has difficulty surviving the rising temperature
59.What's the local residents'attitude towards their sinking city?D
A.Worried.B.Disappointed.C.Concerned.D.Optimistic.
60.What is the main idea of the passage?D
A.Venice is a city with a long history.
B.Experts report that Venice sinks at a fast rate.
C.Venice was once a powerful country.
D.Scientists have a new plan to protect Venice from sinking.

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.

6."Slow City"-a recently launched project focused on preserving the traditional quality of life enjoyed in some of Italy's smaller cities and towns.The project was born from the idea of the"Slow Food"movement-started in Italy in the 1980s-which promotes leisurely eating and the growing of local,healthy products to fight against the American fast-food style.
"The American urban model has invaded our cities,making Italian towns look the same.We want to stop this kind of globalization,"says Paolo Saturnini,an Italian mayor.
The"Slow City"project plans to emphasize the rich,cultural,culinary(厨房的) and artistic local traditions of each community.
Walking areas will be enlarged and squares and parks will be made greener with more plants.Car alarms and other noise that disturbs the peace will be banned,and ugly TV aerials(天线),advertising posters,and signs will be taken down.
City councils will also insist on the use of recycling and renewable energy sources,and will also introduce ecological transport systems.Parking will be made stress-free by creating more public parking areas,and easily accessible walkways and bike lanes will cross the city.But in the"Slow City"way,all improvements will probably come about slowly.
Thirty-two Italian city councils,which joined the"Slow City"program,have decided to take further steps in this direction by increasing the numbers of traditional family-style eating establishments,reducing noise pollution,and concentrating on making their towns friendlier for people to live in.
Organic local produce will be promoted in all restaurants and genetically modified foods(转基因食品) will be banned."We can't stop large,fast-food chains from coming here,but we hope that people who come to our towns will not want to eat exactly the same hamburger they can eat in Melbourne,London or Paris,but want something genuine and different,"said Saturnini.
67.According to the passage,the"Slow City"project aims atD.
A.preventing Italy from being affected by America
B.beautifying the environment of small Italian cities and towns
C.calling on Italians to enjoy stress-free life
D.protecting the traditional Italian lifestyle
68.From Paragraphs 4-5,we can infer thatC.
A.cars in"Slow City"will have to go slowly
B.people can park their cars free of charge in"Slow City"
C."Slow City"will take on an environmentally friendly look
D.advertising in"Slow City"will be banned 
69.Further measures will be included in the"Slow City"program EXCEPTC.
A.cutting down noise pollution
B.stop genetically modified foods
C.getting more towns involved in the project
D.building more family-style restaurants
70.In Saturnini's opinion,when traveling in"Slow Cities",visitorsD.
A.aren't provided with fast food
B.will see few fast-food chains
C.can enjoy themselves like in London
D.can enjoy real Italian-style healthy food.
