Technology is making life easier for some dairy farmers. They use robotic systems to milk their cows. Cows are trained to follow a series of paths that lead to milking stations. Only one cow at a time can enter a station.
Once inside, the cow is rewarded with food. As the cow eats, a robotic arm cleans and connects the animal to the milking machine. A few minutes later, milking is complete. The gate is opened, the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day. The cows get to decide when they want to be milked. Cows are milked an average of about three times a day. Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system. A computer keeps records on their eating and milking. A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk. Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers. She means young people who are more interested in technology and less interested in working all the time on the farm. Still, she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm. Last year it became the fourth farm in southeast Minnesota to get a robotic milking system. A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars. The second cost 150 000.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot. He says the increase in milk production reaches a high of more than six kilograms per cow per day.From the first paragraph, we can infer________.
| A．the robotic system is designed to reduce labor |
| B．cows can be raised by robots in the future |
| C．robots direct cows into milking stations |

Besides milking cows, the robotic system also can ________.
| A．adjust the temperature of milking stations |
| B．judge the quality of fresh milk |
| C．improve the appetite of cows |

Why is the robotic system not popular now?
| A．Because young people have no interest in it. |
| B．Because it is difficult to learn how to use it. |
| C．Because people can’t afford to buy it. |
| D．Because it usually causes the waste of milk. |
According to Doug, what is the wage of an employee?
| A．150, 000-170, 000. | B．750, 000. | C．150, 000 -30, 000. | D．30, 000- 32, 000 |
The best title for the passage may be_______.
| A．Letting robot milk your cow | B．Milking cows by hand |
| C．Improving the quality of milk | D．Drinking fresh milk every day |
A woman from Japan was telling a friend about her trip to the United States.The woman had visited major businesses and investment companies in New York City and Chicago.
“I studied English before I left home，”she said.“But I still was not sure that people were speaking English.”
Her problem is easy to understand.Americans in business are like people who are in business anywhere.They have a language of their own.Some of the words and expressions deal with the special areas of their work.Other expressions are borrowed from different kinds of work such as the theater and movie industry.
One such saying is “get your act together”．
When things go wrong in a business，an employer may get angry.He may shout，“Stop making mistakes.Get your act together.”
Or，if the employer is calmer，he may say，“Let us get our act together.”
Either way，the meaning is the same.Getting your act together is getting organized.In business，it usually means to develop a calm and orderly plan of action.
It is difficult to tell exactly where the saying began.But，it is probable that it was in the theater or movie industry.Perhaps one of the actors was nervous and made a lot of mistakes.The director may have said，“Calm down，now.Get your act together.”
Word expert James Rogers says the expression was common by the late 1970s.Mister Rogers says the Manchester Guardian newspaper used it in 1978.The newspaper said a reform policy required that the British government get its act together.
Now，this expression is heard often when officials of a company meet.One company even called its yearly report，“Getting Our Act Together.”
The Japanese visitor was confused by another expression used by American business people.It is cut to the chase.
She heard that expression when she attended an important meeting of one company.One official was giving a very long report.It was not very interesting.In fact，some people at the meeting were falling asleep.
Finally，the president of the company said，“Cut to the chase.”
Cut to the chase means to stop spending so much time on details or unimportant material.Hurry and get to the good part.
Naturally，this saying was started by people who make movies.Hollywood movie producers believe that most Americans want to see action movies.Many of their movies show scenes in which the actors chase each other in cars，or in airplanes or on foot.
Cut is the director’s word for stop.The director means to stop filming，leave out some material，and get to the chase scene now.
So，if your employer tells you to cut to the chase，be sure to get to the main point of your story quickly.After the woman visited the United States she might feel that ________.
| A．her English was poor |
| B．it’s easy to master English |
| C．it’s difficult to make money |
| D．people there weren’t very friendly |
In which situation could the words “get your act together” be used?
| A．A task is completed successfully. |
| B．Players perform badly in a match. |
| C．Audience is satisfied with the actor’s performance in a movie. |
| D．Visitors make a tiresome and unpleasant trip to someplace. |

| A．was first used by a Japanese businesswoman |
| B．was forbidden to be used in the government policy |
| C．originally came from a yearly report of a company |
| D．was commonly read by readers in a newspaper in 1978 |

| A．Their use. | B．Their meaning. |
| C．Their origin. | D．Their popularity. |
The library is one of the most popular places at a western university.Students turn to it for research，conversations about class，and many other services.
Compared with Chinese libraries，college libraries in the US and UK tend to offer more resources.A postgraduate at Yale University can borrow as many as 225 books at a time.
In addition to borrowing books，there are online and electronic resources.These include a database search of popular and academic material，such as LexisNexis Academic，which offers items from newspapers and magazines.
Although books and articles are the items that students ask for most frequently，some libraries provide audio and video recordings，maps and sheet music(活页乐谱)．At some schools，teachers and tutors put electronic copies of their teaching PPTs on the library web to give easier access for students.
Another useful service in western college libraries is the Interlibrary Loan.This allows a student at one school to borrow books from another school.The loan request is made through the student’s college library，which gets the book，gives it to the user，and arranges for its return.
Technology has brought more services to students and has made libraries attractive.Some universities have services for students to send messages through the computer or mobile texts to ask the library staff for information.
Earlier this year，Harvard University introduced a new Scan and Deliver service，allowing students to make requests for parts of books and articles.Requests made through the system are handled by library staff.The student receives an email with an Internet link to the scanned pages.The service is free and all material comes within four days.
It used to be that libraries didn’t allow food or drinks.But that rule is changing and many of them now contain a café so students can spend as much time as they want in the library.
Actually，some US university libraries are now allnight affairs，or have at least one study room open all night.In western college libraries a postgraduate can ________.
| A．have a free drink or a meal |
| B．borrow as many books as they want |
| C．ask questions and get answers from their tutors |
| D．access not only books but other study resources |
LexisNexis Academic is the name of a ________.
| A．guide | B．library |
| C．database | D．university |
Which of the following are mostly needed by students in western libraries?
| A．Books and articles. |
| B．Audio and video recordings. |
| C．Maps and sheet music. |
| D．Tutors’ teaching PPTs. |
Which of the following statements is TRUE?
| A．Chinese library services are better than western ones. |
| B．Library staff play an important role in college library service. |
| C．Postgraduates can post their own PPTs on the library website. |
| D．24hour services are adopted in all western libraries nowadays. |
The Firegathering
18－20 May
The Firegathering festival returns to an unidentified place somewhere in the Sussex countryside this May.The ticket price is a very agreeable ￡40，an amount that the organisers promise covers only the costs of staging the event.As well as the nightclub singers and dancers and circus performers，you can expect live performances from local stars.If this looks like it might be right for you，you’d be well advised to book your ticket soon；the event has sold out every year since its beginning four years ago.
Sheep Music
20－22 July
Sheep Music started life as a garden party and has developed into a fullscale(全面的) community event.Even though the advertising has always been limited to word of mouth，the huge number of people in 2005 left organizers worried that the large crowds could ruin the festival’s family feel.Luckily July sees the return of this brilliant party.The climax(高潮) comes in the shape of Saturday night’s fullscale parade(游行) and fancy dress ball that you just would not expect to happen in the other sleepy Welsh borders.
The Big Chill
3－5 August
Ten years on and The Big Chill could very well be close to becoming a big pop festival like Glastonbury.That said，the many thousands in attendance are still able to relax in the beautiful Eastnor deer park and listen to plenty of music that would otherwise pass them by.Families have always been given a warm welcome and it’s fair to say that The Big Chill is probably the most childfriendly of all the mediumsized festivals.If you’ve never been，you should certainly go.
Summer Sundae
10－12 August
Although only a year old this summer，Summer Sundae has quickly inspired the imaginations of Leicesteks music lovers.Last year’s event was a success，noted by more than a few mentions at the UK Festival Awards.It is set in the impressive grounds of De Montfort Hall.Although the performers are still to be confirmed，the cabins are sure to be there.These small buildings are made from wood and carpets，storage space，and can fit a family for the night.What can we learn about The Firegathering?

Pessimistic，anxious and depressed people may have a higher risk of dementia (痴呆)，US researchers reported on Thursday.
A study of a group of 3,500 people showed that those who scored high for pessimism on a standardized personality test had a 30 percent increased risk of developing dementia 30 to 40 years later.
Those scoring very high on both anxiety and pessimism scales had a 40 percent higher risk，the study showed.
“There appears to be a doseresponse pattern.That is，the higher the scores，the higher the risk of dementia，”Dr Yonas Geda，a neuropsychiatrist at the Mayo Clinic in Rochester，Minnesota who led the study，said in a statement.
Geda and his colleagues looked at the medical records of 3,500 men and women who lived near the clinic between 1962 and 1965.
They all took the Minnesota Multiphasic Personality Inventory，a standard personality and life experience test，Geda’s team told a meeting of the American Academy of Neurology in Miami.
In 2004，the team interviewed the participants or family members.
Those who scored higher for anxiety and pessimism on the test were more likely，as a group，to have developed dementia by 2004，including Alzheimer’s disease and vascular (血管的) dementia.
This did not mean a person who is pessimistic could assume he or she has a higher risk of developing dementia.
“One has to be cautious in interpreting a study like this，”Geda said.
“One cannot make a leap from group level data to the individual.Certainly the last thing you want to do is to say，‘Well，I am a pessimist；thus，I am doomed to develop dementia 20 or 30 years later，’because this may end up becoming a selffulfilling prophecy (预言)．”
And there is NOT any specific way to prevent dementia，although many studies have shown that a healthy diet，exercise，keeping active in other ways，doing puzzles and other activities lower the risk.What is the passage mainly about?
| A．It is impossible for people to avoid dementia. |
| B．People who always have negative feelings may have a higher risk of getting dementia. |
| C．If we have a healthy diet，we would have no chance of getting dementia. |
| D．A person who is pessimistic has a higher risk of developing dementia. |
According to the passage，which of the following is TRUE?
| A．There are many ways to prevent dementia effectively. |
| B．A person who is pessimistic is sure to get dementia. |
| C．Those who lead a happy life will not get dementia when they are old. |
| D．Those who scored high for pessimism might have a higher risk of dementia. |
Which of the following does NOT help reduce the risk of getting dementia according to the passage?
| A．A healthy diet. | B．Proper exercises. |
| C．Doing puzzles. | D．Getting up early. |
Which of the following words is not close to the meaning of the word “pessimistic”？
| A．Cheerless. | B．Optimistic. |
| C．Unhappy. | D．Upset. |
Mom was right！If you say thank you，for even the smallest gift or slightest show of kindness，you’ll feel happy.
Gratitude(感谢)，says Robert A．Emmons，a professor of psychology at the University of California，is an important element of happiness.In his recent book，Thanks！，Emmons uses the first major study on gratitude to prove mom’s point.In acknowledging and developing this muchignored expression of thankfulness，he explains how people have benefited—even improved their health.
As one of the leading scholars of the positive psychology movement，he admits gratitude may be difficult to express.He advises you to begin by admitting that life is good and full of events and elements that make daily existence a wonder.Second，recognize that the source of life’s goodness is more than just you.That source may be your mom，a friend，partner，child，colleague at work or play，or any combination of these.
Gratitude is always otherdirected，notes Emmons.You can be pleased or angry with yourself and feel guilty about doing something wrong，but you can never be grateful to or for yourself.
Expressing gratitude shouldn’t be a reaction；it should be a state of mind.To feel grateful when life is a breeze and you have more than you need is easy.To feel grateful in time of crisis—anger，hatred and bitterness—is easier.Also，too many people are aware of life’s blessings only after these are lost.The voices expressing gratitude from his studies of individuals are many.
It’s crisis and chaos—danger，disease，disability and death—that bring many individuals to realize just how dependent they are on others.Yet it’s the way each of us begins life and ends it.It’s too bad that so many people waste those decades in between labouring under the illusion(幻觉) they are selfsufficient，says Emmons.
To enable and embrace gratitude，Emmons encourages the readers of Thanks! to keep a gratitude diary.He even provides easytofollow directions on how to practise and develop gratitude.
I’m not a reader or advocate of selfhelp books，but I am thankful for the reference I found in a newspaper article to the research Emmons was conducting on gratitude involving organ donors and recipients(接受者)．The chance discovery led me to this book.
Mom implied that kindness seems to find its way back to the giver because life really is all about giving，receiving and repaying.So I’ll pay attention to her professional advice and say：Thank you，professor Emmons.What is the text mainly discussed?
| A．There are many ways of being thankful. |
