Hidden in a small street in the south end of Springfield, not far from buildings torn apart by the tornado(龙卷风) earlier this year, Frigo’s is an Italian restaurant right in our own backyard.
Frigo’s is not a tiny place. It provides different kinds of Italian food. There are refrigerator cases full of prepared foods and desserts, and shelves filled with olives and various pasta.
There’s some traditional Italian music and the smell is of olive oil and garlic(大蒜). Above the largest refrigerator case, there’s a chalk board covered with desriptions of more Italian sandwiches than I could remember.
I stepped into Frigo’s almost by accident when I had to stay in Springfield into the evening for an open house at the school where I work. Frigo’s is the perfect place to find something quick to go. There are no tables, so all food is taken out. I also thought it would be a great place to pick up some already-prepared food to bring home for dinner.
I ordered the easiest meal possible: a chicken sandwich and a salad. It cost$4.75 for the sandwich. The salad was$4.99 and didn’t have salad dressing on it. I must have missed the choice of salad dressing on the way out. The sandwich was great—great chicken, excellent tomato sauce and not too much cheese.
I wish I had tried one of the many other sandwiches which include Joe’s Favorite ($5.25-$6.75) and the Dante (King) which is made of turkey breast, roasted red peppers, asiago cheese and choice of dressing.
I have a feeling that I’ll be picking up dinner for me and the kids at Frigo’s soon.

B
One of the most difficult questions to answer is how much a job is worth. We naturally expect that a doctor’s salary will be higher than a bus conductor’s wage. But the question becomes much more difficult to answer when we compare, say, a miner with an engineer, or an unskilled man working on an oil-rig(钻油机) in the North Sea with a teacher in a secondary school. What the doctor, the engineer and teacher have is many years of training in order to obtain the necessary qualifications for their professions. We feel instinctively that these skills and these years, when they were studying instead of earning money, should be rewarded. At the same time we recognize that the work of the miner and the oil-rig laborer is both hard and dangerous, and that they must be highly paid for the risks they take.
Another factor we must take into consideration is how socially useful a man’s work is, regardless of the talents he may bring to it. Most people would agree that looking after the sick or teaching children is more important than, say, selling secondhand cars or improving the taste of toothpaste by adding a red stripe to it. Yet it is almost certain that the used car salesman earns more than the nurse, and that research chemist earns more than the school teacher.
Indeed, this whole question of just rewards can be turned on its head. You can argue that a man who does a job which brings him personal satisfaction is already receiving part of his reward in the form of a so-called “psychic(精神的) wage”, and that it is the man with the boring, repetitive job who needs more money to make up for the soul-destroying monotony(单调) of his work. It is significant that that those jobs which are traditionally regarded as “vocations” --- nursing, teaching and the Church, for example --- continue to be poorly paid, while others, such as those in the world of sport or entertainment, carry financial rewards out of all proportion to their social worth.
Although the amount of money that people earn is in reality largely determined by market forces, this should not prevent us from seeking some way to decide what is the right pay for the job. A starting point for such an investigation would be to try to decide the ratio which ought to exist between the highest and the lowest paid. The picture is made more complicate by two factors: firstly by the “social wage”, i.e, the welfare benefits which every citizen receives; and secondly, by the taxation system, which is often used as an instrument of social justice by taxing high incomes at a very high rate indeed. Allowing for these two things, most countries now regard a ratio of 7:1 as socially acceptable. If it is less, the highly-qualified people carrying heavy responsibilities become disillusioned, and might even end up by emigration(移民) (the so-called “brain-drain” is an evidence that this can happen). If it is more, the gap between rich and poor will be so great that it will lead social tensions and ultimately to violence.
74. The professional man, such as the doctor, should be well paid because ______.
A. he has spent several years learning how to do his job
B. his work involves much great intelligence than, say, a bus conductor’s
C. he has to work much harder than most other people
D. he knows more than other people about his subject
75. The “brain-drain” is an evidence that ______.
A. well-educated people are prepared to emigrate whenever they can get a better paid job
B. people with jobs or responsibility expect to be highly paid
C. high taxation is a useful and effective instrument of social justice
D. the poor are generally more patriotic(爱国的) than the rich
76. As far as rewarding people for their work is concerned, the writer, believes that ______.
A. we should pay for socially-useful work, regardless of the person’s talent
B. we should pay people according to their talents
C. market forces will determine how much a person is paid
D. qualified people should be the highest paid
77. The argument of the “psychic wage” is used to explain why ______.
A. people who do socially important work are not always well paid
B. people who do monotonous jobs are highly paid
C. you should not try to compare the pay of different professions
D. some professional people are paid more than others

I have to say that am shocked at just how bad the new music is. This cannot be the same band that produced great albums such as HTDAAB and ATYCLB! This is awful! They either do not care anymore, or have completely lost it. I never thought U2 would become irrelevant, but they have officially become one of those bands that you will now say, “Remember when they were great?”

Total drivel, Mr Harris. The new album is great, far better than the safe, cynical HTDAAB and ATYCLB. U2 have become inventive again, like they were in the 1990s. thank goodness!

Agree, Dan. The new album is the best since Actung Baby. Magnificent is an anthem in the waiting, Breathe is unbelievable, and Stand Up Comedy is absolutely outstanding----- to name just three! Loving the new sound, pure class as usual.

Totally agree with you guys. This album is unbelievable. Breathe is definitely a great song, same with Moment of Surrender. I bet their upcoming tour will be amazing. If you haven’t bought the CD yet, you should. I bought mine on Amozon.com for $3.99. I couldn’t believe it.

     Like many other small boys, I was fascinated by cars, especially because my oldest brother was a bit
of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend. Every so often, one of those magazines would run an article on the "Car of the Future". They featured unconventional things
like small nuclear reactors as power sources. Yet, frankly, my car doesn't do anything that my brother's
Studebaker didn't do. It goes, it stops, it burns gasoline. I still have to steer it, and it still runs into things if
I don't steer it carefully.
     But guess what? All of these things are likely to change in the not-so-distant future. It may not burn
gasoline, I may not have to steer it, and it may be a lot better at not running into things.
Airbags (安全气囊) aren't the be-all and end-all in safety. In fact, considering the recent news about
people occasionally being killed by their airbags in low-speed collisions, they obviously still need some
development. But they aren't going away, and in fact, you can expect to see cars appearing with
additional, side-impact airbags, something some European car manufacturers already offer.
     Better than systems to minimize injury in the event of an accident ,however, are systems that minimize
the likelihood of an accident happening. Future cars may be able to remove many of the major causes of
accidents, including drunk-driving, and tailgating (与前车距离过近). Cars could be equipped with
sensors that can detect alcohol in a driver's system and prevent the car from being started, for example.
As early as next year, you'll be able to buy cars with radar-equipped control systems. If the radar
determines you're closing too quickly with the car in front, it will ease up on the throttle (油门). 
     Will cars eventually be able to drive themselves? There's no reason to think it won't be technically
possible, and Mercedes is working on a system that can brake, accelerate and steer a vehicle down a
highway on its own. Nobody really expects people to give up all control to their cars, but such systems
could be used as failsafe (自动防止故障)systems to keep cars on the road and bring them safely to a
stop even if the driver suddenly became disabled.
1.Why was the author fascinated by cars?
A. Because he read unconventional things about cars in his brother's magazines.
B. Because other small boys liked to own a car of their own, too.
C. Because his oldest brother loved to take him to places in his car.
D. Because he subscribed to cool car magazines.
2. By saying "my car doesn't do anything that my brother's Studebaker didn't do", the author means
     that_____.
A. my car is far better than my brother's    
B. my car is not as good as my brother's
C. much improvement has been made in the design of cars recently
D. not much has changed in the performance of cars so far
3.Which of the following statements is true of airbags?
A. They are going to disappear gradually.
B. They are in need of further improvement.
C. They kill people instead of protecting them in low-speed collisions.
D. They are a standard feature of European cars.
4.According to the author, what will future cars do if the sensors detect alcohol in the driver's system?
A. They will give a warning in advance.
B. They will brake automatically.
C. They will not start.
D. They will ease up on the throttle.
5.Which of the following statements is true according to the last paragraph?
A. Cars will be able to drive themselves.
B. People will give up all control to their cars
C. No cars will ever break down on the roads.
D. Cars will all be equipped with failsafe systems.
