Advertisers tend to think big and perhaps this is why they're always coming in for criticism. Their critics(批评家)seem to hate them because they think this entirely unproductive industry should absorb millions of pounds each year. Why don't they stop advertising and reduce the price of their goods?

The poor consumer! He'd have to pay a great deal more if advertising didn't create mass markets for products. It is precisely(exactly)because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledge we have about household goods comes largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of ones we already know about.

Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway bylaws(rules)while waiting for a train? Would you like to read only closely printed columns of news in your daily paper?

We must not forget, either, that advertising makes a positive contribution to our pockets. Newspapers, commercial radio and television companies could not exist without this source of revenue(税收). The fact that we pay so little for our daily paper, or can enjoy so many broadcast programmes is due entirely to the money spent by advertisers. Just think what a newspaper would cost if we had to pay its full price!

62. From the advertisement we learn that _________ .

A. Camp Chippenstock is intended for all teenagers

B. all the instructors used to be Chippenstock campers

C. we can take part in the camp throughout the summer

D. Camp Chippenstock costs less than many other camps

Each year, an area the size of Beijing plus Shanghai disappears from the Amazon rainforest. On September 30, 2008, Brazil announced that the rate of deforestation increased more than three times in the past year.

The Amazon rainforest covers around 4. 1 million square kilometers of Brazil, nearly 60 percent of the country. The rainforest supports at least 10 percent of the world’s known species. The 17 million people who live in the Brazilian Amazon depend on the land for their homes and livelihoods. Brazil is the world’s biggest beef and soy exporter. Farmers need land for crops and to feed their cattle. Some burn patches of forest to clear the land. Others cut down trees for wood. They build roads to transport the wood.

Brazil’s economy is growing, but that growth comes at a price. In May, Brazil’s environment minister, Marina Silva, quit her job. For six years, she tried to protect the forest. But she felt she was losing the battle against those who are eager to make money in the Amazon.

The Amazon is the planet’s largest absorber of carbon dioxide, a gas that can trap heat in the atmosphere. A world Wildlife Found study shows that 55 percent of the Amazon could be gone by 2030. Without those trees, billions of tons of carbon dioxide would stay in the atmosphere. They would speed up global warming.

Brazilian researchers say that temperatures in the Amazon region will rise by two to three degrees by 2050. That, and the resulting lower rainfall, could turn 30-60 percent of the forest into grassland with only scattered trees.
