On the ground floor of a five story building in Rome, Italy, a lead aproned man carefully places a 400-year-o. ld painting on a table. Then he steps back and flips the switch of a 50,000-volt X-ray machine. Nearby, another painting is being wheeled into a special oven. Elsewhere the buzz of a power saw is heard from behind a closed door. Two workers are cutting the back off a 500-year-old wood panel painting.
Such things happen every day at Rome' s Institute of Restoration. 41)____________In terms of an treasures, Italy is one of the richest countries in the world. Yet until 1939, when Italy' s government founded the Institute, the country" s museums had to hire private restorers for cleaning and repair jobs. Says Doctor Urbani, "Most of the restorers did not have proper training. They often did more harm than good."
No wonder they did harm. 42)____________.
43)____________. Sometimes they even changed the picture.
Any number of things can damage 'an art work. Smog eats away at stone and metal. Insects chew wood. Moisture causes wood and canvas to swell, shrink and finally rot. For one art show, a painting was flown from England to Rome. During the flight, the canvas shrank so much that the paint lost its grip and began peeling. When the box was opened in Rome, there was a halfbare painting——and a pile of tiny colored flakes.
Doctor Urbani remembers, "The painting was rushed to us. It looked hopeless. But we never give up on a case." After months of slow, careful work, every piece of paint had been puzzled back together and glued on a new canvas. The job was so well done that no damage could be seen.
When a painting arrives at the art hospital, it goes to the laboratory, where scientific work is done. Infrared and ultra- violet photographs are taken. 44)____________.Newer coats of paint stand out as dark spots against older coats of paint, if there seems to be a different picture beneath the one showing on the surface, the painting is finally X-rayed.
Paintings on wood are then carried into a boxcar sized room. 45)____________.For 24 hours, a deadly gas seeps into all the cracks in the wood to kill hidden bugs and their eggs. Paintings on torn canvas go to a room where new cloth hackings are glued and ironed on. Finally the paintings are ready to be given new life by one of the restorers.
[A] Instead of just touching up damaged spots, most early restorers painted over them with a heavy hand.
[B] Using these photographs and an analysis of the paint, it began removing dirt and old, yellowed varnish with cotton dipped in a special liquid.
[C] Headed by Doctor Giovanui Urbani, the men and women here work at keeping works of art in good health.
[D] These photographs make it possible to see through the thin top coats of paint to find out if the painting has been touched up or painted over in the past.
[E] They often cleaned paintings with strong black soap, or scrubbed them with raw onions and green apples.
[F] Tile door is sealed shut.
[G] After cleaning, they began the job of filling in the spots where paint was missing.

In 1967, in response to widespread public concern aroused by medical reports of asbestos that related deaths, the National Medical Research Council organized a committee of enquiry to investigate the health threats associated with the use of asbestos in the building industry.
After examining evidences provided by medical researchers and building workers and management, the Council published a report which included advices for dealing with asbestos. The report confirmed the findings of similar research in the United States and Canada. Exposure to relatively small quantities of asbestos fibers, they concluded, was directly responsible for the development of cancers, asbestosis and related diseases. Taking into account evidence provided by economists and building industry management, however, the report assumed that despite the availability of other materials, asbestos would continue to play a major role in the British building industry for many years to come because of its availability and low cost.
As a result, the council gave a series of recommendations which were intended to reduce the risks to those who might be exposed to asbestos in working environments. They recommended that, where possible, asbestos free materials should be employed. In cases where asbestos was employed, it was recommended that it should be used in such a way that loose fibres were less likely to enter the air. The report recommended that special care should be taken during work in environments which contain asbestos. Workers should wear protective equipment and take special care to remove dust from the environment and clothing with the use of vacuum cleaner.
The report identified five factors which determine the level of risk involved. The state and type-of asbestos is critical to determining the risk factors. In addition, dust formation was found to be limited where the asbestos was used when wet rather than dry.
The choice of tools was also found to affect the quantities of asbestos particles that enter the air. Machine tools produce greater quantities of dust than hand tools and, where possible, the use of the latter was recommended.
A critical factor takes place in risk reduction is the adequate ventilation of the working environment. When work takes place in an enclosed space, more asbestos particles circulate and it was therefore recommended that natural or machine ventilation should be used. By closely following these advices, it was claimed that exposure can be reduced to a reasonably practical minimum.
21. Exposure to asbestos fibres can cause cancer ______.

A good marriage means growing as a couple but also growing as individuals. This isn't easy, marriage has always been difficult. Why then are we seeing so many divorces at this time7 Yes, our modern social fabric is thin, and yes the permissiveness of society has created unrealistic expectations and thrown the family into disorder. But divorce is so common be- cause people today are unwilling to exercise the self-discipline that marriage requires. They expect easy joy, like the entertainment on TV, the thrill of a good party.
Marriage takes some kind of sacrifice, net dreadful self-sacrifice of the soul, but some level of compromise. Some of one's fantasies, some of one's legitimate desires have to be given up for the value of the marriage itself. "While all marital partners feel shackled at times, it is they who really choose to make the marital ties into confining chains or supporting bends", says Dr. Whitaker. Marriage requires sexual, financial and emotional discipline. A man and a woman cannot follow every impulse, cannot allow themselves to stop growing or changing.
A divorce is not an evil act. Sometimes it provides salvation (拯救)for people who have grown hopelessly apart or were frozen in patterns of pain or mutual unhappiness. Divorce can be like the first cut of the surgeon' s knife, a step toward new health and a good life. On the other hand, if the partners can stay past the breaking up of the romantic myths into the development of real love and intimacy, they have achieved a work as amazing as the greatest cathedrals(教堂) of the world. Marriages that do not fail but improve, that persist despite imperfections, are not only rare these days but offer a wondrous shelter in which the face of our mutual humanity can safely show itself.
26. According to the author, an ideal marriage life ______.
