1.Scientists in Colombia have trained a team of rats to help remove land mines from the countryside.Land mines are small bombs(炸弹) hidden in the ground and designed to explode(爆炸) when someone steps on them.
When trained,the rats can smell special metals in the mines and then signal(发信号) to their human team.Then why use rats for such an important job?
In the past,dogs have been used to find bombs.Rats have a good sense of smell and can respond to orders,just like dogs do.But rats are much lighter than dogs.They stand less of a chance of setting off the mines,which explode under a certain amount of weight.What's more,the best rats are cheaper to keep than dogs.It costs about the same amount of money to take care of one dog as it does 70rats.
The rats have already been used in Tanzania,an African country with many land mines.Luisa Fernanda Méndez and her team in Colombia are training the even lighter Wistar rats.These are the white rats with red eyes that scientists often use in laboratory experiments."They even train their babies to perform their jobs,which saves us a lot of time,"Méndez said.
Colombia has the second-highest rate(比率) of deaths from land mine accidents in the world.Last year,land mines killed 695people-56of whom were children.A criminal(犯罪的)group called the Revolutionary Armed Forces of Colombia,or FARC,as well as other organizations,have placed the mines.FARC are strongly against Colombia's government.The group has placed mines all around its own bases and in many places in the countryside.
In the past,the Colombian government hired peasants and poor farmers to find mines.Many of them died trying to find the well-hidden bombs.
Colombian police official Erick Guzmán hopes the team of rats can come to the rescue(援救)."These rats will be a great help,"he said.
32.How do rats help to find land mines?C
A.By their special sight.
B.By their light weight.
C.By their sense of smell.
D.By their excellent hearing.
33.The advantage of rats over dogs in finding bombs is thatD.
A.they are cleverer.
B.they run faster
C.they have a better sense of smell
D.they don't make mines explode as easily
34.The underlined word"They"may refer toB.
A.scientists                  
B.Wistar rats
C.dogs                        
D.Méndez and her team
35.What is the passage mainly about?A
A.Specially-trained rats help clear land mines.
B.People in Tanzania are suffering from land mines.
C.Dogs are no longer used to find land mines.
D.Land mines have become a great danger to Colombians.

11.Two years ago,a Dutch creative company opened a concept restaurant in Amsterdam that would be,in the words of its founder,"the perfect place to have dinner alone."The restaurant is called Eenmaal-this name has been translated into English as"dinner for one"-and was launched in an attempt to start removing the stigma(污名) connected to going out alone.Obviously picking up on the same cultural trend,a new fast-casual restaurant in Washington,D.C.has seating with individual dishes,an arrangement that satisfies single diners.
A study in the Journal of Consumer Research gets at why most people are so unwilling to leave home and do fun things on their own.In a series of experiments,the University of Maryland's Rebecca Ratner and Georgetown's Rebecca Hamilton showed that when it comes to going to the movies or to dinner,subjects(受试者) are in agreement that they won't enjoy themselves as much if they aren't going with any of their friends."People decide not to do things all the time just because they're alone,"Ratner told The Washington Post."But the thing is that they would probably be happier going out and doing something all by themselves."
The researchers found the main reason people didn't think they'd enjoy themselves was that they were afraid other people would think they didn't have any friends.They thought they'd be seen as unusual,antisocial,and strange for going somewhere without friends,but said they wouldn't attach these labels(标签) as strongly to someone they witnessed,say,sitting alone at a movie theater.
Ratner and Hamilton also ran some experiments to see how they might be able to push people to go out by themselves.They realized that there wasn't the same mental block against going to the grocery store alone,and supposed that this was because shopping stood for getting something done.Sure enough,subjects who considered going to a coffee shop on their own thought it sounded more enjoyable when they were told they would have reading material and could be productive than when they were going simply to enjoy a drink.Getting people to think of an experience as an accomplishment might make them more likely to do it without a friend's company.
In the absence of fellow diners,many of the customers at Eenmaal,the blog Food Republic reported,ended up staring at their phones anyway.These days,when a phone is never farther than an arm's length away,"alone"just doesn't mean what it used to.
25.The two restaurants mentioned in Paragraph 1were opened toB.
A.offer delicious and healthy food to customers
B.encourage people to have dinner out alone
C.satisfy different requirements from different customers
D.spread local culture and customs among visitors
26.According to Rebecca Ratner,what is the surprising finding of their research?C
A.It's hard for people to decide whether to go out with friends or by themselves.
B.People would rather stay at home than do something amusing out.
C.There may be more pleasure when doing things alone than with others.
D.People should learn some social skills and enjoy staying with others.
27.According to the passage,people who want to do things with their friendsA.
A.care much about others'opinions about them
B.have emotional or mental problems
C.are too busy to complete their tasks alone
D.are greatly affected by their friends

A.securityB.belongingC.achievement   D.responsibility.
12.Whether we're 2 years old or 62,our reasons for lying are mostly the same:to get out of trouble,for personal gain and to make ourselves look better in the eyes of others.But a growing body of research is raising questions about how a child's lie is different from an adult's lie,and how the way we deceive changes as we grow.
"Parents and teachers who catch their children lying should not be alarmed.Their children are not going to turn out to be abnormal liars,"says Dr.Lee,a professor at the University of Toronto and director of the Institute of Child Study.He has spent the last 15 years studying how lying changes as kids get older,why some people lie more than others as well as which factors can reduce lying.The fact that children tell lies is a sign that they have reached a new developmental stage.Dr.Lee conducted a series of studies in which they bring children into a lab with hidden cameras.Children and young adults aged 2 to 17 are likely to lie while being told not to look at a toy,which is put behind the child's back.Whether or not the child takes a secret look is caught on tape.
For young kids,the desire to cheat is big and 90% take a secret look in these experiments.When the test-giver returns to the room,the child is asked if he or she looked secretly.At age 2,about a quarter of children will lie and say they didn't.By 3,half of kids will lie,and by 4,that figure is 90%,studies show.
Researchers have found that it's kids with better understanding abilities who lie more.That's because to lie you also have to keep the truth in mind,which includes many brain processes,such as combining several sources of information and faking that information.The ability to lie-and lie successfully-is thought to be related to development of brain regions that allow so called"executive functioning",or higher order thinking and reasoning abilities.Kids who perform better on tests that involve executive functioning also lie more.
62.What's the purpose of children telling lies?B
A.To help their friends out.
B.To get rid of trouble.
C.To get attention from others.
D.To create a popular image.
63.The underlined word"deceive"in Paragraph 1 can be replaced by"B".

9.In order to know a foreign language well,four things are necessary.First,we must understand the language when we hear it spoken.Secondly,we must be able to speak it ourselves,with confidence and without hesitation(犹豫).Thirdly,we must do much reading.Finally,we must be able to write it.We must be able to make sentences that are correct in grammar.
There are no shortcuts to success in language learning.A good memory is a great help,but it is not enough only to memorize the rules from a grammar book.It is not much learning by heart long lists(一览表)of words and their  meanings,studying the dictionary and so on.We must learn by using the language.
If we are pleased with a few rules we have memorized,we are not really learning the language.We must"learn through use."Practice is important.We must practise speaking and writing the language whenever we can.

46.The most important things to learn a foreign language areA
A.understanding and speaking      
B.listening,speaking,reading and writing

B.he doesn't have a good memory
C.he always remembers lists of words and their meanings
D.he often hesitates(犹豫)to practise speaking it
48.One can never learn a foreign language well byB.
A.doing much practice     
B.studying the dictionary
C.learning through use     
D.using the language

C.we can learn a language well while we are keeping using it
D.we must learn everything by learning a language.
16.Memory,they say,is a matter of practice and exercise.If you have the wish and really made a conscious(自觉的) effort,then you can quite easily improve your ability to remember things.But even if you are successful,there are times when your memory seems to play tricks on you.
Sometimes you remember things that really did not happen.One morning last week,for example,I got up and found that I had left the front door unlocked all night,yet I clearly remember locking it carefully the night before.
Memory"trick"work the other way as well.Once in a while you remember not doing something,and then find out what you did.One day last month,for example,I was sitting in a barber shop waiting for my turn to get a haircut,and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.
We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness.Stories about absent-minded professors have been told for years,and we never get sick of hearing new ones.Unfortunately,however,absent-mindedness is not always funny.There are times when"trick"of our memory can cause us great trouble.

D.Get Rid of Absent-mindedness.
6.In 1826,a Frenchman named Niepce needed pictures for his business.But he was not a good artist.So he invented a very simple camera (照相机).He put it in a window of his house and took a picture of his garden.That was the first photo.
The next important date in the history of photography (摄影术) was in 1837.That year,Daguere,another Frenchman,took a picture of his reading room.He used a new kind of camera in a different way.In his picture you could see everything very clearly,even the smallest thing.This kind of photo was called a Daguerreotype.
Soon,other people began to use Daguere's way.Travelers brought back wonderful photos from all around the world.people took picture of famous buildings,cities and mountains.
In about 1840,photography was developed.Then photographers could take picture of people and moving things.That was not simple.The photographers had to carry a lot of film and other machines.But this did not stop them,for example,some in the United States worked so hard.
Mathew Brady was a famous American photographers.He took many picture of great people.The picture were unusual because they were very lifelike(栩栩如生的)
Photographers also became one kind of art by the end of the 19th century.Some photos were nor just cookies of the real world.They showed and feelings,like other kinds of art.
46.The first photo taken by Niepce was a picture ofC
A.his business     
B.his house       
C.his garden

D.a photographer
48.If a photographer wanted to take pictures of moving things in the year of 1840,he had toD.
A.watch lots of films 
B.buy an expensive camera
C.stop in most cities 
D.take many films and something else with him.

13.You may have experienced the annoyance of being fined because of parking illegally or finding your car towed away(拖走)after leaving it parked somewhere for a couple of minutes.But now a high-tech car sticker that's designed to be stuck to a car's windscreen could help motorists avoid such a situation.
The TowStop sticker sends a text message to a driver when touched by a traffic policeman,to allow motorists to send a reply and give them time to move their cars immediately.Frankfurt-based IT consultant,Daniel Kalliontzis,came up with the idea and is raising money to put his£43sticker into production.
Car owners can put the sticker inside their car's windscreen,having set it up with key information,such as their phone number.The slim design will include a sensor(传感器)that,when touched by a traffic policeman,will send a text message warning a driver of a possible fine.The driver could then type a reply for the policeman using a smartphone,which will appear on the sticker's screen.
The smart sticker system will rely on the good will of traffic policemen and in a way,a German law.The law states:an officer has to choose the most efficient and inexpensive way for the car owner to remove the vehicle.It could be cheaper for the government to call the driver than to tow his car.
Mail Online asked the Department of Transport whether the sticker could be used in the UK in a similar way.A spokesman said,"In England there is no legal duty to warn the motorist before issuing the ticket.However,a policeman does have the discretion not to issue a ticket if he doesn't think the situation is that bad or he just wants to issue a warning."
So far,Mr.Kalliontzis has raised just over£2,362of his£39,381goal.If he manages to raise the money,the stickers will be shipped in June 2015.But it appears that car owners using the smart system could get some unnecessary warning messages,because anyone could touch the smart sticker.
28.The author wrote the third paragraph toA.
A.explain how a smart car sticker works
B.advise drivers to buy a car sticker
C.show the importance of a sensor
D.tell drivers how to park a car
29.We may infer from the text that in BritainB.
A.car owners don't have to worry about a parking ticket
B.smart car stickers wouldn't work as well as in Germany
C.traffic policemen prefer to call a driver rather than tow his car
D.the Department of Transport thinks highly of smart car stickers
30.The underlined word"discretion"in Paragraph 5can best be replaced by"C".
A.trouble     
B.pressure       
C.freedom 
D.opportunity
31.What would be the best title for the text?D
A.Daniel Kalliontzis-a great inventor

D.End of the parking ticket?
10.Many animals recognize their food because they see it.So do humans.When you see an apple or a piece of chocolate you know that these are things you can eat.You can also use other senses when you choose your food.You may like it because it smells good or because it tastes good.You may dislike some types of food because they do not look,smell or taste very nice.Different animals use different senses to find and choose their food.A few animals depend on only one of their senses,while most animals use more than one sense.
Although there are many different types of food,some animals spend their lives eating only one type.The giant panda eats only one particular type of bamboo.Other animals eat only one type of food even when given the choice.A kind of white butterfly will stay on the leaves of a cabbage,even though there are plenty of other vegetables in the garden.However,most animals have a more varied diet.The bear eats fruits and fish.The fox eats small animals,birds and fruits.The diet of these animals will be different depending on the season.
Humans have a very varied diet.We often eat food because we like it and not because it is good for us.In countries such as France and Britain,people eat foods with too much sugar.This makes them overweight,which is bad for their health.Eating too much red meat and animal products,such as butter,can also be bad for the health.Choosing the right food,therefore,has become an area of study in modern life.

21.We can infer from the text that humans and animalsC.
A.depend on one sense in choosing food
B.are not satisfied with their food
C.choose food in similar ways
D.eat entirely different food
22.Which of the following eats only one type of food?A.
A.The white butterfly.
B.The small bird.
C.The bear.
D.The fox.
23.Certain animals change their choice of food whenA.
A.the season changes
B.the food color changes
C.they move to different places
D.they are attracted by different smells
24.We can learn from the last paragraph thatD.
A.food is chosen for a good reason
B.French and British food is good
C.some people have few choices of food
D.some people care little about healthy diet.
11.U.S.Open Championships
The US Open has been in existence for more than 120 years.The first tournament(锦标赛)was held in 1881 at the Newport Casino.It was called the US National Singles Championship.Entry was limited to only those clubs which were members of the United States National Lawn Tennis Association,and the competitors were all male,competing in both singles and  doubles.Richard Sears won the men's championship and he went on to win the next six men's singles championships.
The Wimbledon
