Why does cream go bad faster than butter? Some researchers think they have the answer, and it comes down to the structure of the food, not its chemical composition(成分)—a finding that could help break away from some chemicals. Cream and butter contain pretty much the same things, so why cream should go bad much faster has been a problem. Both are small globules(液滴) of one liquid spread throughout another. The difference lies in what’s in the globules and what’s in the surrounding liquid, says Brocklehurst, who led the research. In cream, fatty globules drift about in a sea of water. In butter, globules of a watery road are locked away in a sea of fat. The bacteria(細菌) which make the food go bad prefer to live in the watery areas of the mixture. “This means that in cream, the bacteria are free to grow throughout the mixture, ” he says. When in butter, the bacteria are locked away in locked places buried deep in the sea of fat. Trapped in this way, those colonies cannot spread and rapidly run out. They also slowly poison themselves with their waste products. “In butter, you get a self-limiting system which stops the bacteria growing, ” says Brocklehurst. The researchers are already working with food companies eager to see if their products can be made to stand bacterial attack through changes of the food’s structure. Brocklehurst believes it will be possible to make something used in salad cream for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid state.
1. The importance of Brocklehurst’s research is that _______.
A. it suggested a way to keep some foods fresh without using some chemicals
B. it discovered small globules in both cream and butter
C. it showed the secret of how bacteria increase in cream and butter

D. produce less waste in cream than in butter
3. According to Brocklehurst, we can keep cream fresh by _______.
A. removing its fat B. killing the bacteria
C. reducing its water D. changing its structure
4. The underlined word “colonies” refers to _______.
A. tiny globules B. watery regions

The UK has a wellrespected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all， sometimes it can be confusing.
October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends， join lots of clubs and settle into university life.
However， having just left the comfort of home and all your friends behind， the prospect(前景) of meeting lots of strangers in big halls can be nervewracking(令人頭痛的). Where do you start？ Who should you make friends with？ Which clubs should you join？
Luckily， there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
Here are some top advice from past students on how to survive Freshers’ Week：

●Be sociable. The more active you are， the more likely you’ll be to meet new people than if you’re someone who never leaves their room.

As the economy begins to recover, salary increases should do the same.
In the past few years, employers have raised workers’ salaries by about 4 percent per year--except for 2009, when the figure dropped to a historically low 2.1 percent, according to a survey of World at Word. About one-third of companies froze raises altogether.
For 2010, World at Work’s survey projects an average salary increase budget of 2.7 percent, a figure that shows the situation has improved but the job market is still weak. Between 10 percent and 15 percent of companies said they would freeze raises--far fewer than in 2009, but still more than in most years.
How can you get a raise? Avalos and others offer the following tips:
* Do your job well. This means producing high-quality work, of course, but also keeping the big picture in mind.
“It really comes down to positioning yourself as a high performer, somebody who is aware of business goals and helps the company meet their goals as an organization”, Avalos said
* Be visible. When times are tough, some workers think. “I’m going to hunker down and hope that nobody notices me, because I don’t want to be on a layoff list,” said Richard Phillips, owner of Advantage Career Solutions. This is a mistake, because you’re unlikely to get a raise if no one knows what you have accomplished. “If anything, what you want to do is be more visible.”
* Make your boss’s life easier. This means everything from having a good attitude to taking on extra tasks. If you don’t know how you can help your boss, ask.
* Ask for a raise. Talk to your boss and present your case: Here’s what I’ve done, here’s how it fits with the company’s goals, and here is why I think it’s worth a salary increase. In some cases, even if your company has an official raise freeze, you can get a raise if you make good case.
If the answer is no -- or if you’re not ready to ask directly -- Phillips suggests asking, “What would you like to see from me that would put me in line for a raise?”
A question like this can improve your standing. “Just asking the question says to the boss, ‘I’m thinking about where I fit in here, what I can do,” Phillips said, “That in and of itself has value.”
1.The passage is mostly from a\an________.
A. novel B. science fiction
C. magazine D. biography
2.Employers have raised workers’ salaries by about _______percent in 2007.
A. 4 B. 2.1 C. 2.7 D. 10
3.If you want to get a raise, the most important thing you should keep in your mind is to ______.
A. have your job done well B. be visible everywhere as possible as you can
C. ask your boss for a raise directly D. change your job
4.All the statements are true except________.
A. the situation has improved but the job market is still weak
B. salary increases should recover as the economy does
C. producing high-quality work will surely help you get a raise
D. that in and off an employee makes no difference

Although women lead healthier, longer lives, the cruel opinion that they become "old” sooner than men is widespread in the workplace, research shows.
A survey of more than 2,600 managers and personnel professionals showed that age discrimination is not only common in the workplace, but is shot through with inconsistencies (矛盾).
Six in ten managers reported being a victim of age discrimination -- usually because they were turned down for a job for being too old or too young. Yet more than a fifth admitted that they used age as an important standard.
Although the survey found widespread agreement that older workers were better than younger colleagues when it came to reliability, commitment (承擔義務), loyalty (忠誠) and customer service, these qualities were not necessarily considered to be worthy of advancement.
A large number of persons believed that workers between 30 and 39 had the best promotion chances, with only 2 per cent giving examples of 50-year-olds or above.
There was evidence that people were considered old at different ages in different jobs. A young man working in IT said he was considered too old by the age of 28.
In fact there was no evidence to suggest that older workers were less valuable to companies than younger workers, in fact the opposite was often true because older workers often brought experience.
The findings also suggested that the Government's ideas on age in the workforce may also be out of step with reality.
63.Which is the discrimination mentioned in this passage?
A. The healthier women are, the sooner they will lose their jobs.
B. Society knows women should be respected, but it doesn't offer them any jobs.
C. Female managers respect male workers, but male managers don't respect female workers.
D. victims of age discrimination consider age as an important standard.
64.Older workers are better than younger colleagues because they have many advantages except that they are _____.
A. dependable B. married C. faithful D. helpful
65.Why does the writer mention a young man working in IT?
A. Because the writer thinks it a pity that this young man is old.
B. Because it's an example of different age standards in different jobs.
C. Because IT industry is developing too fast.
D. Because the writer doesn't think the young man is old.
66. Which statement is true according to the writer's attitude?
A. The present age standard doesn't go with reality.
B. The present age standard is reasonable.
C. women should work longer than men.
D. Young workers should learn from old workers.

Hidden in our subconsciousness (潛意識) is a perfect mental picture. We see ourselves on a long trip that goes across the continent. We are traveling by train. Out the windows, we think in the passing scene of cars on nearby highways, of children waving at a crossing, of cattle feeding on a distant hillside, of smoke pouring from a power plant, or row upon row of corn and wheat, of flat lands and valleys, of mountains and rolling hills, of city skylines and village halls.
But uppermost in our minds is the final destination. On a certain day at a certain hour, we will pull into the station. Bands will be playing and flags waving. Once we get there, so many wonderful dreams will come true and the pieces of our lives will fit together like a completed jigsaw（拼圖玩具） puzzle. How restlessly we pace the aisles(通道), condemning the minutes for loitering --waiting, waiting, waiting for the station.
“When we reach the station, that will be it!” we cry. “When I’m 38.” “When I buy a new 450SL Mercdes Benz!” “When I put the last kid through college.” “When I have paid off the!” “When I get a promotion.” “When I reach the age of retirement, I shall live happily ever after! ”
Sooner or later, we must realize there is no station, no one place to arrive at once and for all. The true joy of life is the trip. The station is only a dream. It constantly outdistances us.
“Relish(appreciate) the moment” is a good motto, actually it isn’t the burdens of today that drive man mad. It is the regret over yesterday and the fear of tomorrow. Regret and fear are twin thieves who rob us of today.
So stop pacing the aisles and counting the miles. Instead, climb more mountains, eat more ice cream, swim more rivers, watch more sunsets, laugh more and cry less. Life must be lived as we go along. Then the station will come soon enough.
1.Why does the author describe the mental picture?
A．To lead us into a perfect world. B．To let people enjoy the scenery.

A．Regret and fear are responsible for the loss of today.
B．We must be careful of the two thieves: regret and fear.
C．regret and fear stop us from enjoying our present life.
D．We’re frequently challenged by the two : regret and fear.
4.Why does the author write the passage?
A．To teach us a good lesson. B．To tell us the right attitude to life.

Someday a stranger will read your e-mail without your permission or scan the Website you've visited，Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits.
In fact, it's likely that some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girl friend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen ---- the 21st century replacement of being caught naked.
Psychologists tell us boundaries are healthy, that it's important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs(碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret.
The key question is: Does that matter?
For many Americans, the answer apparently is "no."
When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey found a strong bad feeling about privacy, with 60 percent of respondents saying they feel their privacy is "slipping away, and that bothers me."
But people say one thing and do another. Only a tiny part of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收費站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will give away personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon(優(yōu)惠卷)。
But privacy does matter ---- at least sometimes. It's like health: When you have it, you don't notice it. Only when it's gone do you wish you'd done more to protect it.
1.What does the author mean by saying "the 21st century replacement of being caught naked"?
A. People's personal information is easily accessed without their knowledge.
B. In the 21st century people try every means to look into others' secrets.
C. People tend to be more frank with each other in the information age.
D. Criminals are easily caught on the spot with advanced technology.
2.What would psychologists advise on the relationships between friends?
A. Friends should open their hearts to each other.
B. Friends should always be faithful to each other.
C. There should be a distance even between friends.
D. There should be fewer arguments between friends.
3.Why does the author say "we live in a world where you simply cannot keep a secret"？
A. Modern society has finally developed into an open society.
B. People leave traces around when using modern technology.
C. There are always people who are curious about others' affairs.
D. Many search engines benefit from giving away people's identities.
4.What do most Americans do as for privacy protection?
A. They change behaviors that might disclose their identity.
B. They use various loyalty cards for business transactions(交易)..
C. They rely most and more on electronic devices.
D. They talk a lot but hardly do anything about it.
5.According to the passage, privacy is like health because ___.
A. people will make every effort to keep it.
B. its importance is rarely understood
C. it is something that can easily be lost
D. people don't treasure it until they lose it
