Each day every person in the United States throws away more than five pounds of garbage(垃圾). There is more garbage now than ever before and most of it is made up of the packages and cans in which we put our food. The traditional way of getting rid of solid wastes is quickly becoming inadequate. Many cities are experimenting with newer ways of handling their growing piles of garbage.
One of these new ways is "recycling"(回收使用). Through recycling usable materials are taken out of garbage and made into something else. These usable parts of garbage are put through the cycle of going from a raw material to a finished product again.
In some cities a machine called Hydrapulper is being used to help recycle garbage. A Hydrapulper is like a huge mixing machine. The garbage is dropped onto a conveyor belt (传送带) that feeds the machine. At the same time, water is pumped into the Hydrapulper. With a mixing action, the Hydrapulper throws out the heavy metal objects tha
A. It throws away glass and sand from garbage.
B. It collects heavy metal objects for selling.
C. It separates garbage into useful and useless things.
D. It pumps water into garbage and mixes it.
Passage Five
Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.
Eleven gray whales have died in the San Francisco Bay in the last three weeks. No one knows why the whales are dying.
Last year 270 whales died along the whales’ migration route. Many people think starvation is the cause. This year the dead whales seem to have more blubber (fat) on them.
Twenty years ago, the gray whale was listed as an endangered species.
Some scientists think that the larger number of whales makes it hard to find enough food. More whales create more pressure on the food supply, a supply that some scientists say may have dwindled as a result of the warm waters of E1 Nino.
Most of the whales have been dead for many days before they are found and studied. This makes it hard to find the reason for death.
65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year
A. the whales travel such a long distance
B. there are more whales than there used to be
C. the whale bodies are too old to study by the time they are found
D. the whales are endangered
Every year New Zealanders living in London can be seen loading up Kombi vans and heading off to experience the "classic European holiday", The trip usually starts in the north of France, after crossing the channel from Dover in England to Calais, driving down through France, over the Pyrenees into Spain, west into Portugal and then across the Continent to Italy and often beyond.
There are numerous reasons young New Zealanders take this rite of passage—as well as seeing all the fantastic sights and tasting the delights of Europe’s food and wine, it’s relatively inexpensive. The Kombi is transport and accommodation all in one, cutting down significantly on costs.
There is just one problem. As the Kombis become "antique", these trips are usually punctuated with numerous roadside sessions as the van sits idle, in no hurry to start, while you swelter in the hot sun. But do not let this deter you. Travelling Europe in your own vehic
A. The Kombis become too old.
B. Language.
C. People may not enjoy the driving experience.
D. Finding one's destination is hard for the busy traffic in cities.
