Only recently have they come to think of it as something to look through. Stores display their goods in large glass windows. Glass bottles and jars that hold food and drink allow us to see the contents. Glass is used to make eyeglasses, microscopes, telescopes, and many other extremely useful and necessary objects. Until the Second World War, most of the glass used for optical instruments was imported from Europe. However, during the war Americans could not get European glass, and they were forced to make their own. Therefore, new kinds of glasses were developed that had been previously unknown. These new effects were achieved by mixing other chemical elements with the sand. Some of these new glasses are very strong and can resist many kinds of shocks. Legend has it that a very hard glass was invented by a Roman who showed his discovery to the Emperor. When the Emperor saw the glass he feared that it would become more valuable than gold and sliver, making his treasure worthless. Therefore, he had the glassmaker killed, and the secret was not discovered again for hundreds of years. In the present century, safety glass was invented for use in modern cars and planes. Safety glass is made by placing a layer of plastic between two layers of plate glass. When the outside layer of glass is broken, the pieces do not scatter and injure people. Some glass of the type is strong enough to resist bullets . Although nowadays plastics have replaced glass under conditions where glass might be easily broken, there are new uses being developed, for the greatest advantage of glass is that its component parts are inexpensive and can be found all over the world. Question: As time goes by, glass _ . - is regarded as transparent - is used to make things look pleasant - is seen as more than decoration - is widely used to replace steel in making containers
is seen as more than decoration

Read the following article and select the best answer. Article: I have recently completed my college degree. The last project was called "Smile". The class was asked to go out to smile at three people and document their reactions. I am a very friendly person and always smile at everyone and say hello anyway. So, I thought this would be a piece of cake. My husband, youngest son and I went out to McDonald. We were standing in line when all of a sudden everyone around us began to back away. As I turned around I smelled a horrible body odour and saw two poor homeless men standing behind me. As I looked at the short blue-eyed gentleman closest to me, he was "smiling". The second man fumbled with his hands as he stood behind his friend. The young lady at the counter asked him what they wanted. He said, "Coffee is all, Miss," because that was all they could afford. Then I really felt it-I embraced the little man with the blue eyes. That is when I noticed all eyes in the restaurant were set on me, judging my every action. I smiled and asked two more breakfast meals on and gave them to the men. The blue-eyed gentleman looked up at me, with tears in his eyes, and said, "Thank you." When I sat down my husband smiled at me. We held hands for a moment and at that time, we knew that because of the good fortune that we had been given. I turned in my project. My teacher said, "Can I share this?" I slowly nodded as she got the attention of the class. She began to read and that is when I knew that we as human beings share this need to heal people and to be healed. In my own way I had touched the people at McDonald's and every soul that heard the story in the classroom. But, I graduated with one of the biggest lessons I would ever learn. Question: Why did the two men only buy coffee? - Because they didn't have enough money. - Because they didn't feel hungry. - Because they knew others would help them. - Because they were looked down upon.
Because they didn't have enough money.

Article: Sadness is unpleasant, and in a society where personal happiness is prized above all else, there is little tolerance for falling in despair. Especially now we've got drugs for getting rid of sad feelings -- whether it's after losing a job, the break-up of a relationship or the death of a loved one. So it's no surprise that more and more people are taking them. But is _ really such a good idea? A growing number of voices from the world of mental health research are saying it isn't. They fear that the increasing tendency to treat normal sadness as a disease is playing fast and loose . Sadness, they argue, serves a useful purpose--and if we lose it, we lose out. Yet many psychiatrists insist not. Sadness has a nasty habit of turning into depression , they warn. Even when people are sad for good reason, they should take drugs to make themselves feel better. So who is right? Is sadness something we cannot live without or something horrible never to touch? There are lots of ideas about why feeling sad should become part of human life. It may be a self-protection strategy, as other primates also show signs of sadness. A losing monkey that doesn't show sadness after it loses a fight may be seen as continuing to challenge the winning monkey -- and that could result in death. In humans sadness has a further function: we may display sadness as a form of communication. By acting sad, we tell other community members that we need support. Then there is the idea that creativity is connected to dark moods. There are plenty of great artists, writers and musicians who have suffered from depression or disorder. Scientists found that people with signs of depression performed better at a creative task, and negative moods make people think deeply over the unhappy experience, which allows creative processes to come to the front. There is also evidence that too much happiness can be bad for your career. A doctor found that people who scored 8 out of 10 on a happiness test were more successful in income and education than 9s...
