It is said that there’s no such thing as a free lunch, but even if you manage to bag a bargain meal, it will not taste as good as a more expensive choice, according to scientists.

A new study has found that restaurant goers who pay more for their meals think the food is tastier than offered for a smaller price. The experts think that people tend to associate cost with quality and this changes their perception(感知) of how food tastes.

Scientists at Cornell University studied the eating habits of 139 people enjoying an Italian buffet in a restaurant. The price of the food was set by the researchers at either $4 or $8 for the all-you-can-eat meal. Customers were asked to rate how good the food tasted, the quality of the restaurant and to leave their names.

The experiment showed that the people who paid $8 enjoyed their meal 11% more than those who ate the “cheaper” buffet. Interestingly those that paid for the $4 buffet said they felt guiltier about loading up their plates and felt that they overate. However, the scientists said that both groups ate around the same quantity of food in total.

Brian Wansink, a professor of consumer behavior at the university, said: “We were fascinated to find that pricing has little effect on how much one eats, but a huge effect on how you interpret the experience.” He thinks that people enjoyed their food more as they associated cost with quality and that small changes to a restaurant can change how tasty people find their meals.

In a previous study, researchers from the university showed that people who eat in bright lighting consume more than people who eat in less brightly lit areas.

A. there were 139 subjects involved in the new study

B. a free lunch might be as delicious as you expected

A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment.

The unpunctual man, on one hand, never does what he has to do at the right time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be regained. Time is more valuable than material things. In fact, time is life itself. The unpunctual man is for ever wasting and mismanaging his most valuable asset (財(cái)產(chǎn)) as well as others. The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments promptly. But the man who really has a great deal to do is very careful of his time. He knows that he can not get through his huge amount of work unless he faithfully keeps every piece of work when it has to be attended to.

Failure to be punctual in keeping one’s appointments is the sign of disrespect towards others. If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him. Usually this will be regarded as a great disrespect to the host and all other guests present.

Unpunctuality, moreover, is very harmful when it comes to one’s duty, whether public or private. Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time. A man who is known to be habitually unpunctual is never trusted by his friends or fellow men.

1.What does the author think is the main difference between a punctual person and an unpunctual person?

A. A punctual person does everything ahead of time.

B. An unpunctual person never does anything at the right time.

C. A punctual person has a lot of appointments.

D. An unpunctual person has little time to do anything.

2.According to the passage, the main reason that a person is always unpunctual is that _______.

A. he has more work to do than other people

B. he is always in a hurry when he works

C. he doesn’t care much about time

D. he always mismanages and wastes his time

3.If someone isn’t punctual in keeping his appointments, he might ________.

A. lose his life

B. mismanage his asset

C. be thought to disrespect others

D. do harm to others

4.According to the third paragraph, when you are invited to dinner, you should arrive there ________.

A. after other guests

B. before other guests

C. at the appointed time

D. after the host getting things ready

5.Which of the following statements best describes the harm of unpunctuality?

A. If you are an unpunctual person, you cannot be in charge of any important task.

B. If your friends know that you are unpunctual, they may not see you again.

C. Unpunctuality may bring about heavy losses for both public and private affairs.

D. Unpunctuality may make you miss a lot of appointments and lose friends.

My soccer coach retired in last week. I wanted to do anything special for him at his retirement party. My mum makes the better biscuits in the world, so I decide to ask her for help. Mum taught me some basic step of baking. I insisted on doing most of the baking myself. I thought the biscuits were really well. My only mistake was that I dropped some on the floor after I was packing them up.

At a party, my coach, with a biscuit in his mouth, asked surprisingly who made them and joked, “I might have to retire again next year get some more of these biscuits.”

My favorite picture at the party is of my coach and me enjoy the biscuits with happy laughter!

No one knows exactly how many disabled people there are in the world，but estimates suggest the figure is over 450 million. The number of disabled people in India alone is probably more than double the total population of Canada.

In the United Kingdom，about one in ten people have some disability. Disability is not just something that happens to other people：as we get older，many of us will become less mobile，hard of hearing or have falling eyesight．

Disablement can take many forms and occur at any time of life. Some people are born with disabilities．Many others become disabled as they get older. There are many progressive disabling diseases．The longer time goes on，the worse they become. Some people are disabled in accidents．Many others may have a period of disability in the form of a mental illness. All are affected by people’s attitude towards them．

Disabled people face many physical barriers．Next time you go shopping or to work or to visit friends，imagine how you would manage if you could not get up steps, or onto buses and trains. How would you cope if you could not see where you were going or could not hear the traffic? But there are other barriers: prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through，so it is important to draw attention to these barriers and show that it is the individual person and their ability，not their disability，which counts．

1.The key word in Paragraph 4 is_______.

A. disability B. ignorance

C. prejudice D. Barriers

2.The last word of the passage “counts” most probably means_______.

A. being most important B. being considered

C. being included D. being numbered

3.Which of the following statements is NOT true according to the passage?

A. Even the able-bodied may lose some of their body functions when they get older.

B. There are about 10 percent disabled persons in the UK.

C. The whole society should pay attention to the barriers faced by the disabled people.

D. There no longer exists prejudice against the disabled.

4.It can be concluded from the passage that_______.

A. we should try our best to prevent disablement

B. both physical and mental barriers are hard to break down

C. we must take a proper attitude towards the disabled

D. the able-bodied people will never fully understand the disabled
