Damage to Ozone Layer Gets Worse
In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer．The warning: The sun's summertime rays are more dangerous than once thought.
A team of scientists from 80 nations recently reported
to the United Nations that a layer of ozone（臭氧层）in the atmosphere, which protects humans from harmful levels of ultraviolet（紫外线）radiation, will be thinner over the United States this summer．The thinner layer allows more ultraviolet rays from the sun to reach Earth．The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.
Scientists first became concerned about the layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter．The hole was caused in chemicals used in refrigerators and air conditioners．When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.
Concern about the protective ozone layer rose more recently when data from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica．Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.
Although many countries have already begun stopping the use of ozone-destroying chemicals, the new findings are expected to advance the timetable for a total ban of the chemicals.
【小题1】The scientists have observed the ozone layer ______．
| A．since 1980 | B．since last winter |
| C．for more than 20 years | D．for about one year |
| A．do a lot of good to human beings in many ways |
| B．protect humans from diseases caused by bad weather |
| C．do a lot of harm to human beings in the summer-time |
| D．protect humans from harmful levels of ultraviolet radiation |
| A．above Arctic during the winter in the mid-1980s |
| B．above Antarctica during the winter in the mid-1980s |
| C．over somewhere in the north of the equator in 1980 |
| D．over the USA in the summertime in the mid-1980s |
| A．the changeable weather | B．ozone-destroying chemicals |
| C．chemicals from refrigerators | D．chemicals from air conditioners |

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days！”
These are the kinds of statements used in magazine，newspaper，radio and television ads，promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs，slim the face，smooth wrinkles，or in some other way to add to beauty or desirability.
Often such products are nothing more than moneymaking things for their promoters. The results they produce are questionable，and some are dangerous to health.
To understand how these products can be legally promoted to the public，it is necessary to understand something of the laws covering their regulation. If the product is a drug，FDA(Food and Drug Administration)can require proof under the Food，Drug，and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device，FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health，FDA can request the producer or distributor to remove it from the market voluntarily， or it can take legal action，including seizure(查封)of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor，which had been sold for reducing the waistline (腰围). The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously，most of the devices on the market have never been the subject of court proceedings(法律诉讼)，and new devices appear continually. Before buying，it is up to the consumer to judge the safety or effectiveness of such items.
【小题1】It can be inferred that the ads mentioned in the text are________.
| A．objective | B．costly | C．unreliable | D．illegal |
| A．if it is a drug |
| B．if it is a device |

| A．a product which was designed to produce electricity |

Across countryside, non-food crops are growing alongside wheat．Some are used in new alternatives to plastics and other materials, but others will simply be burned．
Burning crops is becoming more popular because it is good for the planet．Doing so is also cheaper than burning fossil fuels．As more land is devoted to non-food crop production, the economics of crops for fuel are likely to become even more favorable．
Humans have been burning such biomass—organic materials from plants or animals— since they discovered fire．But that burning fossil fuels could have catastrophic consequences has brought biomass back into fashion．
Even allowing for emissions (排放) of carbon dioxide from fuel used in planting, harvesting, processing and transporting biomass fuel, replacing fossil fuel with biomass can typically reduce greenhouse gas emissions by more than 90 percent．
Power stations around the world are experimenting with forms of biomass to add to their coal or oil, with encouraging results．Indeed, power companies could profit by turning to biomass, especially when the subsidies (补助) many governments offer for using renewable energy are taken into account．
Farmers can benefit from growing biomass．In Europe, the reduction of subsidies for certain crops is exposing farmers to market forces．Instead of being paid for whatever they produce, farmers must seek a clear demand for their product．Many believe that the demand for alternatives to fossil fuels could be just such a driver．
But while biomass offers a variety of potential alternatives, the world's infrastructure (基础设施） has developed around burning fossil fuels to such a stage that switching to biomass involves a change in conception that many companies have not accepted．
Also, there are problems with using biomass．Although most coal-fired power stations could take a small amount of their fuel from biomass without significant adjustment, few are built to run on biomass alone．Burning some forms of biomass also causes environmental problems．Oils and waste can be smelly, while wood produces smoke unless burned properly．
The supply chains for fossil fuels are set up well, but those for biomass are just the beginning. Sources of supply for biomass rely on farm production and can therefore be less reliable. They are necessarily limited and it wouldn't make sense to turn a very large amount of valuable agricultural land away from food crops．But as the world adjusts to the need to control greenhouse gas emissions, these problems may receive more attention．
1.What do we know about biomass?
A．It is a useful way of burning crops．
B．It is plant and animal matter used to provide power．
C．It is a new alternative to be used widely．
D．It is a popular approach to fighting against pollution．
2.What are the advantages of using biomass?
a．It gives off less greenhouse gases．
b．It helps farmers receive subsidies for what they produce．
c．It has met the clear demand for energy．
d．It has brought subsidies for some power companies．
e．It is cheaper than burning fossil fuels．
A．a, b, c B．b, c, d C．c, d, e D．a, d, e
3.For coal-fired power stations, ______．
A．more effective ways to use biomass have been tried
B．using renewable energy has become their daily task
C．burning biomass alone would require considerable changes
D．setting up dependable supply channels needs governments' support
4.What is the author's attitude towards biomass fuels?
A．Defensive． B．Doubtful． C．Negative． D．Objective
