高三英语毕业班暑期适应性练习题八(3)

Every time you go to the supermarket, you come away with your purchases packed in plastic bags. But wouldn’t it be kinder to the environment if you asked for paper bags instead?

The answer is not as easy as it might seem. Environmentalists say there are drawbacks to using both plastic bags and paper bags.

According to the American Plastic Council, 80 percent of groceries in the US are packed in plastic bags.

“The numbers are becoming huge,” said Vincent Cobb, a businessman from Chicago who set up reusable bags. com on the Internet. He notes that consumers use between 500 billion and one trillion plastic bags per year worldwide.

Some experts believe that all these bags harm the environment. Plastic takes hundreds of years to break down and, as it does so, poisonous materials are released into the water and soil.

Further damage is caused of plastic bags enter the sea. For example, endangered sea turtles cannot tell the bags from jellyfish(水母), their main source of food, and often choke on them.

Floating plastic bags have been spotted as far north as the Arctic Ocean and as far south as the southern end of South America. One expert predicts that, within ten years, plastic bags will wash up in Antarctica!

However, this kind of bag does have its advantages.

“Plastic grocery bags are some of the most reused things around the house,” explained Laurie Kusek of the American Plastics Council.

According to the Film and Bag Federation, a trade grouping the US Plastic industry, paper bags use more energy and create more waste than plastic bags. Plastic bags require 40 per cent less energy to produce and cause 70 per cent less air pollution, the group explained. They also release as much as 94 per cent less water into the water than paper ones.

But paper bags do break down more quickly than plastic bags. They don’t endanger wildlife, either.

So what should we do? One possible solution would be to use biodegradable plastic bags. “Biodegradable” means that the bags break down naturally, just like a piece of banana peel when it is left outside.

But until biodegradable technology improves, it might be easier to pack things you buy in reusable cloth bags.

Michael, a typical American, stays home on workdays. He plugs into his personal computer terminal in order to connect with the office.

The world of business is one area in which technology is isolating(分开) us. Experts say, for example, that many people will soon be able to work at home.

For many people now, however music is an individual experience. Walking along the street or sitting in their living rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing, too. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing videotapes to watch at home.
