If you want to live longer and lower the risk of heart disease, a move to the mountains may help． Research by scientists in Greece shows that living in the mountains is good for the heart and longevity． People living at higher altitude have lower possibility of dying from heart disease than those closer to sea level, even if they have factors that could increase their risk．"Residence in mountainous areas seems to have a 'protective effect' from heart disease," said Dr Nikos Baibas of the University of Athens．He and his colleagues suspect that the increased exercise from walking up mountainous area gives the heart a good workout and enables it to cope with lower levels of oxygen．
Researchers studied the health records and death rates of 1,150 Greeks who lived in three villages near Athens over 15 years．One village was 1,000 metres above sea level and the other two were in low-lying areas．Although men and women living in the mountainous village had higher blood pressure rates and other risk factors than people in the other villages, they had a lower rate of death from heart disease and other causes after a fifteen year follow-up．"The contrast was more evident among men than among women," Baibas added in a report in the Journal of Epidemiology and Community Health．Heart disease is one of the world's top killers．Smoking, high blood pressure, raised cholesterol levels, being overweight or obese and a family history of the illness increase the odds of developing the disease．

When we can see well, we do not think about our eyes often．It is only when we can not see perfectly that we come to see how important our eyes are．
People who are nearsighted can only see things that are very close to their eyes．Many people who do a lot of close work, such as writing and reading, become nearsighted．Then they have to wear glasses in order to see distant things clearly．
People who are farsighted face just the opposite problem．They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length．If they want to do much reading, they must get glasses too．
Other people do not see clearly because their eyes are not exactly the right shape．This, too, can be corrected by glasses．Some people’s eyes become cloudy because of cataracts．Long ago these people often became blind．Now, however, it is possible to operate on the cataracts and remove them．
When night falls, colors become fainter to the eyes and finally disappear．After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers．Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction．This is because when you turn your head, you are looking at the thing too directly．Men on guard duty sometimes think they see something moving to one side of them．When they turn to look straight at it, they can not see it any more, and they believe they were mistaken．However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark．
64．We don’t know that our eyes are of great importance until ________．
A．we think about our eyes B．we cannot see clearly
C．we wear glasses D．we have to do much reading
65．According to the passage, a ________ is more likely to be nearsighted．

A．can do a lot of close work without glasses
B．can only see things that are very close to their eyes
C．have difficulty reading a book if they hold it at arm’s length
D．can correct their eyes by glasses
67．To see a small thing at night, it is better to look ________ ．

Most musicians agree that the best violins were first made in Italy．They were made in Cremona, Italy, about 200 years ago．These violins sound better than any others．They even sound better than violins made today．Violin makers and scientists try to make instruments like the old Italian violins．But they aren’t the same．Musicians still prefer the old ones．No one really knows why these old Italian violins are so special, but many people think they have an answer．
Some people think it is the age of the violins．They say that today’s violins will also sound wonderful someday．But there is a problem here．Not all old violins sound wonderful．Only those from Cremona are special．So age cannot be the answer．There must be something different about Cremona or those Italian violin makers．
Other people think the secret to those violins is the wood．The wood of the violin is very important．It must be from certain kinds of trees．It must not be too young or too old．Perhaps the violin makers of Cremons knew something special about wood for violins．
But the kind of wood may not be so important．It may be more important to cut the wood in a special way．Wood for a violin must be cut very carefully．It has to be the right size and shape．The smallest difference will change the sound of the violin．Musicians sometimes think that this was the secret of the Italians．Maybe they understood more than we do about how to cut the wood．
Size and shape may not be the answer either．Scientists measured these old violins very carefully．They can make new ones that are exactly the same size and shape．But the new violins still do not sound as good as the old one．Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny．It also helps the sound of the instrument．No one knows what the Italian violin makers used in their varnish．So no one can make the same varnish today．
There may never be other violins like the violins of Cremona．Their secret may be lost forever．Young musicians today hope this is not true．They need fine violins．But there aren’t very many of the old violins left．Also, the old violins are very expensive．Recently, a famous old Italian violin was sold for about US $ 300,000!
60．This passage is about _______．
A．making violins B．musical instruments

Early in the 16th century men were trying to reach Asia by traveling west from Europe. In order to find Asia they had to find a way past South America. The man who finally found the way from the Atlantic Ocean to the Pacific was Ferdinand Magellan (麦哲伦). Magellan sailed from Seville in August, 1519 with five ships and about 280 men. Fourteen months later, after spending the cold winter on the coast of Patagonia, he discovered the channel which is now called Magellan Strait(海峡). In November, 1520, after many months of dangers from rocks and storms, the three remaining ships entered the ocean on the other side of South America. They then continued, hoping to reach Asia. But they did not see any land until they reached the islands off the coast of Asia. Before they arrived at these islands, later known as the Philippines (菲律宾), men were dying of starvation (饥饿). While they were staying in the Philippines, Magellan was killed in battle. The remaining officers then had to get back to Spain. They decided to sail round Africa. After many difficulties, one ship with eighteen men sailed into Seville three years after leaving. They were all that remained of Magellan’s expedition. However, their achievement was great. They were the first men to sail round the world.

Many cities in the world are benefiting from the nocturnal (夜间活动的) activities of a group of people who call themselves guerrilla (游击队的) gardeners. Armed with trowels, spades and a van full of flowers and plants, guerrilla gardeners turn abandoned urban land into a blaze of color. In city centre locations where there was mud, weeds and empty plastic bottles, residents often wake up to find that the wasted area has been transformed overnight with brightly-colored bedding plants.
In most British cities, local governments and police turn a blind eye to the exploits (开发) of the gardeners, whose activities are always carried out under cover of nightfall. And so far, there has been nothing but praise from the astonished and delighted local residents when they find their neighborhood transformed in such a striking fashion.
Not only do the guerrilla gardeners beautify neglected places, they also return regularly to water the plants and weed the flower beds. They also make sure that at least some of the plants they bring are evergreens, which means that the area doesn’t look dismal (凄凉的) in the winter months.
The first guerrilla gardener in London was Richard Reynolds, whose day job is at an advertising agency. Mr Reynolds, a graduate of Oxford University, began his efforts two years ago when he moved to a flat in a tower block in South London. From his balcony, he could see several empty concrete pots, placed by the local governments to contain plants but never used. He went out after midnight and filled the pots with plants, and then planted more flowers in the path leading to the entrance to the block.
He then set up a website to explain his plan and called upon more gardeners to join him. Cash donations flooded in and, more importantly, volunteers rushed to be part of the campaign. Within six months, there were five hundred people in London prepared to come out at very short notice to revitalize (恢复活力) neglected parts of the urban landscape. There are now unofficial but carefully-organized groups in many cities in Britain and North America and there is also a website where would-be urban gardeners can find out the location of the next expedition.
