People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes from cars. Statistics show that 93 percent of all auto trips are within cities. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country.
On the average, we throw away more trash and garbage than the year before. The burning of garbage contributes to air pollution. Many major industries are also responsible for the dirty air in the around cities. The fumes from iron, steel, chemical, and petroleum production add particles to the air.
The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy for traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode. In some of the larger cities, these fumes endanger the live of human beings by contributing to lung diseases and causing early death.

The latest fashion in kitchen is the food steamer． All the stores are selling them; everyone wants one． Steaming is one of the simplest and healthiest ways of cooking food．However, that cooking time is usually longer than with other methods． In case you’re thinking of buying a steamer, I've done a survey about the steamers available on the market to help you decide which will suit you best．
●Folding Steamer
The simplest and least expensive is the folding stainless-steel （不锈钢）version．
Advantages: This is a good, basic design which sits inside a variety of different shapes of pans with the water under it; a ring in the center allows for easy lifting and it's easy to clean．
Disadvantages: It only holds small dishes． Also, if you put too much water in the pan, it will boil up through the vegetables and they will be watery． If you put too little water in and let it get dry, you will burn the pan and get strange-smelling vegetables．
●Steaming Pan
This is a three-layered black Teflon-coated version with a lid and two double-handled steamers, which sits on the oven ring． The brand I bought is called Nutritious Living．
Advantages: This is an excellent steamer, lightweight, easy to clean, and of all the steamers I've tried, this cooks the fastest． Fish and chicken can be cooked on the bottom with rice or vegetables on the top． It's easier to store．
Disadvantages: Water can boil away until the pan is dry, but if you make sure you fill the pan up to the suggested level and do not overcook the food, this should not happen．You cannot see the food cooking from the top． It doesn't supply a dish for cooking rice．
For serious users of steamers, I recommend having one of each version． If you just want to try it, get the folding stainless-steel type．Why did the author carry out the survey________.
| A．To inform people of different steamers |

The Nutritious Liuing steamer________．

"Shark on the bait （诱饵） !" shouted Andre Harman, pointing to a spot a few yards behind the outboard motors． His voice gave no indication of panic, but the crew suddenly became tense and fixed their eyes on the water． Slowly, smoothly, Andre drew in the bait．The shark followed． No one asked what kind of shark it was． Everything about it, from its color to its shape, tells that it was a great white shark．
Andre lifted the bait aboard． Placing himself between the two motors, he dropped his right hand into the water just as the great head reached the first motor．“My goodness Andre!” I said． His hand seized the big nose, moving it away from the tube of the motor, guiding the shark's head up as it rose out of the water． Andre's hand held the nose, touching it gently． No one spoke． No one breathed． The moment seemed endless． In fact, it lasted less than five seconds before Andre pulled his hand back．
Still nobody spoke． Then Andre smiled and said: "The first time was an accident． I was just trying to move the shark away from the motor． Sharks are attracted to motors by r．heir electrical signals and have a habit of biting them to see if they are eatable． " Andre has worked with great white sharks for years． "My hand landed on its nose, and it sort of paused, so I kept it there, and when I did let go, the shark bit and bit as if it was searching for whatever it was that had attracted it．"
Nearly every encounter （遭遇） we had had with the great whites had been totally illogical． The more we learned, the more we realized how little was really known about them in the past years． Back then, it was generally accepted that great whites ate people by choice． Now we know that almost every attack on a human is an accident in which the shark mistakes a human for its normal food． Back then, we thought that once a great white smelt blood, it would lead to death． Now we know that nearly three-quarters of bite victims survive, perhaps because the shark recognizes that is has made a mistake and doesn't return for a second bite．The author said, "My goodness! Andre ! " when ________．
| A．Andre was about to fall into the water |
| B．Andre was about to touch the shark |
| C．Andre was followed by the shark |
| D．Andre was bitten by the shark |
What does the author think of the encounters with great whites________.
| A．Exciting． | B．Educational． |
| C．Frightening | D．Reasonable |
Most bite victims survive in shark attacks because________.
| A．they are taught how to fight off sharks |
| B．sharks discover they are no threats |
| C．they manage to swim to safety |
| D．sharks stop attacking them |
For many years, women could only be seen on the seat behind the men operating the two-wheeled motorcycle. Now more and more women are taking the front seat. More than twenty million people in the United States ride motorcycles.
Since 1998 the number of female（女性）bikers has risen sharply. Lady Sport Riders began in 1999 in Washington. The women formed the organization to share their love of motorcycle riding. But later it wanted to be more than just an organization for women to gather and ride motorcycles, so it started to organize events that help national health organizations and women’s shelters. It also permits women to share a strong sisterhood, and gives financial awards to poor students. Like other motorcycle clubs, the members of Lady Sport Riders also help their community.
Different from male riders, female riders ride for more than fun. This sport gives women a sense of freedom and control. Female riders have helped change motorcycle culture. More than five years ago manufacturers began making equipment especially for women. Some bikes now have smaller, softer seats and controls that are easier to reach. Modern clothes for riding now look good and still provide protection. In the past, women rode motorcycles that traveled at a moderate speed. Now theirs are as powerful as the ones men ride. Safety is very important when riding because the risk (危险) of injury is high. So the women wear protective clothing and equipment at all times, especially for the head.
Lady Sport Riders believes women have earned their place in the sport of motorcycle riding. When speaking of male motorcyclists, the members of the club say, “They Made the Game. We Came to Play!”

In many countries the standard of living enjoyed by their people has increased rapidly in recent years. Sadly, not everyone in these countries is so fortunate and many people in rich countries are homeless.
The reasons for homelessness are various, but poverty（贫穷）is undoubtedly one of the main causes. The homeless people may have become jobless and then been unable to pay their rent and so no longer have a roof over their heads. Often, the fact that unemployed people get help from the government prevents this from happening, but not always.
Some homeless people are mentally ill and have no one to look after them. Some are young people who, for one reason or another, have left home and have nowhere to live. Many of them have had a serious disagreement with their parents and have left home, choosing to go to a city and live on the streets. Sometimes they have taken such action because they have been unable to get on with a step-parent.
Many homeless people get into the habit of begging to get enough money to stay alive, but many of the general public refuse to give anything to beggars. Often they are moved on by the police, being accused （指控），whether rightly or wrongly, of forceful begging . There are many who disrespect homeless people.
Some cynics（愤世嫉俗的人）declare that homeless people choose to live the life which they lead. But who would willingly choose to live in a shop doorway, under a bridge or in a cardboard box?According to the text, what causes some people to be homeless?
