Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas.  

Most Americans would find it hard to imagine what life would look like without cars.  . The polluted air becomes poisonous and dangerous to health.

  . That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else.   . Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down.  .

Although cars have led us to a better life, they have also brought us new problems.

A.Thus the problem of air pollution would become less important than that of unemployment.

B. Americans know cars very well.

C. However, some have realized the serious problems of the air pollution that is caused by cars.

D. One way to get rid of the polluted air is to build a car that does not pollute.

E. However, the number of vehicles has continued to increase in recent years.

F. Americans won’t live without cars!

G. Inventors are now working on steam cars as well as electric cars.

       Every day we experiencc one of the wonders of the world around us without even realizing it It is not the amszing complexity of television. Nor the impressive tcchnology of transport The universal wonder we share and

Experience is our ability to make noises with our mouths, and so transmit ideas and thoughts to each other’s minds. This ability comes so naturally that tend to forget what a miracle（奇迹）it is.

       Obviously, the ability to talk is something that marks humans off from animals. Of course, some animals have powers just as amazing. Birds can fly thousands of miles by observing positions of the stars in the sky in relation to the time of day and year. In Nature’s went show, humans are a species of animal that have deve pod their own special act. If we reduce it to basie ferms, it’s a ability for communicating information to ther by varying sounds we make as we breathe out.

       Not the to don’t have other powers of communication. Our facia. expressions convey our emotions, such as anger, or jout or disappointment. The way we hold our beads can indicate to others whether we are happy or sad. This is so-called “body language”. Bristling(直立的)fur is an unmistakable warning of attack among many animals. Similarly, the bowed bead or drooping tail shows a readiness to take second place in any animal gathering.

       Such a means of communication is a basic mechanism that animals, including human beings, instinctively acquire and display. Is the ability to speak just another sort of instinct? If so, how did human beings acquire this amazing skill? Biologists can readily indicate that particular area of our brain where speech mechanisms function, but this doesn’t tell us how that part of our bodies originated in our biological history.

Every year thousands of tourists visit Pompeii, Italy. They see the sights that Pompeii is famous for—its stadium(运动场)and theatres, its shops and restaurants. The tourists do not, however, see Pompeii's people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2 000 years.

Once, Pompeii was a busy city of 22 000 people. It lay at the foot of Mount Vesuvius, a grass?covered volcano(火山). Mount Vesuvius had not erupted(喷发)for centuries, so the people of Pompeii felt safe. But they were not.

In August of AD 79, Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ash began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.

For centuries, Pompeii lay buried under stone and ash. Then, in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly,carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in AD 79. There were streets and fountains, houses and shops. There was a stadium with 20 000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue colour in the bottom, so we know that the people of Pompeii liked wine. They liked bread too, metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread—a type of bread that is still sold in Italy today.

Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eyemakeup.

Ginseppe has died, but his work continues. One fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.

One event that helps educate young people about things they can do for others is National Youth Service Day (NYSD). Every year on this day, organizations all over the country celebrate young volunteers, educate young people about how they can help their country, and invite them to participate in service projects. Former Secretary of State Colin Powell said, “National Youth Service Day honors young volunteers and is an invitation to others to join hands and do our part as Americans.”

Founded in 1988, NYSD originally took place on a Tuesday. Now the event lasts from Friday until Sunday so that more people can participate in it. More than 200 organizations work together to create thousands of projects each year. Millions of young people across the United States take part in these service projects.

Long before the event, people, community groups, schools, and nonprofit organizations think of ways to meet their communities’ needs. Then, they plan projects for young volunteers. Projects include bringing food to hungry people, tutoring younger children and helping senior citizens. During the event, young people from the community do things like planting neighborhood gardens and cleaning up local parks.

The organizations that contribute to NYSD believe that volunteering and community service are important activities for people of all ages, but especially for young people. Young people who volunteer are more likely to do well in school, vote, and contribute to charities. More important, they help other people and make the world a better place for everyone.
