Passage ThreeHow can we get rid of garbage.9 Do we have enough energy sources to meet our future energy needs?These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the time it can save the land to hold garbage.For a long time, people buried garbage or dumped it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source. Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs.44. What two problems can man solve by burning garbage?A. The shortage of energy and air pollution.B. The shortage of energy and the land to hold garbage.C. Air pollution and the shortage of fossil fuel.D. Air pollution and the shortage of land to hold garbage.

第二篇Shopping at Second-Hand Clothing StoresWhen 33-year-old Pete Barth was in college,shopping at second-hand clothing stores was just something he did一“like changing the tires on his car."He looked at his budget and decided he could save a lot of money by shopping for clothes atthrift shops." Even new clothes are fairly disposable（可丢掉的）and worn out after a couple of years , " Barth said. "In thrift shops,you can find some great stuff whose quality is better than new clothes."Since then,Barth,who works at a Goodwill thrift shop in the US state of Florida,has found that there are all kinds of reasons for shopping for second一hand clothing.Some people,like him,shop to save money.Someshop for a crazy-looking shirt. And some shop as a means of conserving energy and helping the environment. Pat Akins , an accountant at a Florida Salvation Army (SA)（救世军）thrift shop, said that, for her, shopping at thrift shops is a way to help the environment."When my daughter was little,we looked at it as recycling,"Akins said."Also,why pay 30 dollars for a new coat when you can get another one for a lot less?"Akins said that the SA has shops all over the US一“some as big as department stores".All of the clothes are donated（捐赠）,and when they have a surplus（盈余）,they' ll have "stuff-a-bag" specials, where customers can fill a grocery sack with clothes for only 5 or 10 dollars.Julia Slocum,22,points out,however,that the huge amount of second-hand clothing in the US is the result of American wastefulness."I'd say that second-hand stores are the result of our wasteful,materialistic culture,"said Slocum,who works for a pro-conservation organization,the Center for a New American Dream."Thrift shops prevent the waste from going to landfills（垃圾填埋场）;they give clothing a second life , provide cheaper clothing for those who can' t afford new ones and generate（生成）income for charities. They also provide a way for the wealthy and middle classes to shed（摆脱）some of the guilt for their level of consumption."Thrift shops can do everything EXCEPT__________.A:give clothing a second lifeB:generate income for charitiesC:provide cheaper clothes for the poorD:stop rich people from wasting money

Thirst for OilWorldwide every day,we devour the energy equivalent of about 200 million barrels of oil.Most of the energy on Earth comes from the Sun.In fact enough energy from the Sun hits the planet's surface each minute to cover our needs for an entire year,we just need to find an efficient way to use it. So far the energy in oil has been cheaper and easier to get at. But as supplies dwindle,this will change,and we will need to cure our addiction to oil.Burning wood satisfied most energy needs until the steam-driven industrial revolution,when energy-dense coal became the fuel of choice.Coal is still used,mostly in power stations,to cover one quarter of our energy needs,but its use has been declining since we started pumping up oil.Coal is the least efficient,unhealthiest and most environmentally damaging fossil fuel,but could make a comeback,as supplies are still plentiful:its reserves are five times larger than oil's.Today petroleum,a mineral oil obtained from below the surface of the Earth and used to pro- duce petrol,diesel oil and various other chemical substances,provides around 40% of the world's energy needs,mostly fuelling automobiles.The US consumes a quarter of all oil,and generates a similar proportion of greenhouse gas emissions.The majority of oil comes from the Middle East,which has half of known reserves.But other significant sources include Russia,North America,Norway,Venezuela and the North Sea.Alaska's Arctic National Wildlife Refuge could be a major new US source,to reduce reliance on foreign imports.Most experts predict we will exhaust easily accessible reserves within 50 years,though opinions and estimates vary.We could fast reach an energy crisis in the next few decades,when demand exceeds supply.As conventional reserves become more difficult to access,others such as oil shales and tar sands may be used instead.Petrol could also be obtained from coal.Since we started using fossil fuels,we have released 400 billion tonnes of carbon,and burn- ing the entire reserves could eventually raise world temperatures by 13℃．Among other horrors, this would result in the destruction of all rainforests and the melting of all Arctic ice. Which country is the biggest consumer of petroleum?A: The United States.B: Russia.C: Norway.D: Venezuela.

A Great Quake Coming?Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's bound to happen someday. At least seven active fault（断层）lines run through the San Francisco area. Faults are places where pieces of Earth'S crust（地壳）slide past each other.When these pieces slip,the ground shakes.To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre- diet how bad the damage might be when the next one happens.One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists had assumed at the time. During small earthquakes,faults rupture（断裂）at about 2.7 kilometers per second. During bigger quakes,however.ruptures can happen at rates faster than 3.5 kilometers per second.At such high speeds,massive amounts of pressure build up,generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses（脉冲）traveled away from the city during the 1906 event.As bad as the damage was,it could have been far worse.Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data, however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62percent.New buildings in San Francisco are quite safe in case of future quakes.Still,more than S4 percent of the city’s buildings are old and weak.Analyses suggest that another massive earthquake would cause extensivedamage.People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while.According to the new research,however,it's not a matter of"if" the Rig One will hit.It',just a mat-ter of when.Scientists will be able to predict the exact time of an earthquake soon.A:RightB:WrongC:Not mentioned
