Energy and Public Lands
The United States boasts substantial energy resources. Federal lands provide a good deal of US energy production,the US Department of the Interior manages federal energy leasing (租赁)both on land and on the offshore Outer Continental Shelf Production from these sources amounts to nearly 30 percent of total annual US energy production.
In 2000,32 percent of US oil,35 percent of natural gas,and 37 percent of coal were pro-duced from federal lands,representing 20,000 producing oil and gas leases and 135 producing coal leases. Federal lands are also estimated to contain approximately 68 percent of all undis-covered US oil reserves and 74 percent of undiscovered natural gas.
Revenues from federal oil,gas,and coal leasing provide significant returns to US taxpayers as well as State Government. In 1999,for example,$553 million in oil and gas revenues were paid to the US Treasury,and non-India coal leases accounted for over$304 million in revenues,of which 50 percent were paid to State governments. Public lands also play a critical role in energy delivery. Each year , federal land managers authorize(许可)rights of way for transmission lines , rail systems , pipe-lines,and other facilities related to energy production and use.
Alternative energy production from federal lands falls behind conventional energy pro-duction , though the amount is still significant. For example , federal geothermal(地热)re-sources produce about 7. 5 billion kilowatt-hours(千瓦时)of electricity per year,47 percent of all electricity generated from US geothermal energy. There are 2,960 wind turbines on public lands in California alone,producing electricity for about 300,000 people. Federal hydropower (水电)facilities produce about 17 percent of all hydropower produced in the United States.
Because of the growing US thirst for energy and increasing public unease with depend-ence on foreign off sources,pressure on public lands to meet US energy demand is becoming more intense. Public lands are available for energy development only after they have been evaluated through the land use planning process.If development of energy resources conflicts with management or use of other resources,development restrictions or impact moderation measures may be enforced,or mineral be banned altogether.
Geothermal resources,wind turbines,and hydropower facilities in Paragraph 4 are ci-ted as examples to illustrate that______.
A: alternative energy production is no less than conventional energy production
B: they are the most typical conventional energy resources from public lands
C: geothermal resources are more important than the other two
D: the amount of alternative energy production from public lands is huge

U. S. Blacks Hard-hit by Cancer
Death rates for cancer are falling for all Americans,but black Americans are still more
likely to die of cancer than whites,the American Cancer Society said Monday.
In a special report on cancer and blacks,the organization said blacks are usually
diagnosed with cancer later than whites,and they are more likely to die of the disease.
This could be because of unequal(不平等的)access to medical care , because
blacks are more likely to have other diseases as well,and perhaps because of differences
in the biology(生物学)of the cancer itself, the report added.
"In general,black Americans have less hope of surviving five years after diagnosis
than whites for all cancer sites and all stages of diagnosis,"the report said.
"In describing cancer statistics for black Americans,this report recognizes that many of the
differences associated with race may be caused by unfair social and economic
differences and unequal access to medical care."
The cancer society said blacks should be encouraged to get check-ups(体格检查)
earlier,when cancer is more treatable,and it said more research is needed to see if
biological differences play a role.
"The new statistics emphasize the continuing importance of wiping out these unfair
social differences through public policy and education efforts,"the organization said in a
statement.
But it also noted a drop in cancer death rates.
"Cancer death rates in both sexes for all sites combined have dropped greatly among
black Americans since 1992,as have incidence rates(发生率),"said the report.
Which may NOT be a reason for higher cancer death rates among U.S. blacks?
A:Unequal access to medical care.
B:Greater probability of having other diseases.
C:Differences in the biology of the cancer.
D:Early diagnosis.

Look After Your Voice
Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in your mouth.First gently bite the edges of your tongue with your teeth.Or,press your entire tongue to the bottom of your mouth and hold it there until the saliva flows.Or you can imagine that you are slicing a big juicy lemon and sucking the juice.
Before you begin your talk,be kind to your voice,Avoid milk or creamy drinks which dry your throat. Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.
If you sense that you are losing your voice,stop talking completely.In the meantime,do not even talk in a low voice.Save your voice for your health.You may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If it is necessary,perhaps you can get some advice from a professional singer.
What about drinking alcohol to wet your throat?I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain and your mouth do not work together properly.Save the alcohol until after you finish speaking.
Perhaps you want to accept the advice,but you may wonder if you can ever change the habits of a lifetime .Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,“We learn to skate in the summer and swim in the winter”.Take this message to heart and give yourself time to develop your new habits.If you are willing to change,you will soon be able to say that you will never forget these techniques because they became a part of your body.
To solve the problem of dry mouths,one is advised to take cool milk.

Gross National Happiness
In the last century,new technology improved the lives of many people in many countries.However,one
country resisted these changes.High in the Himalayan mountains of Asia,the kingdom of Bhutan remained
separate. Its people and Buddhist(佛教)culture had not been affected for almost a thousand years. Bhutan,
however,was a poor country.People died at a young age.Most of its people could not read,and they did not
know much about the outside world.Then,in 1972,a new ruler named King Jigme Singye Wangchuck de-
cided to help Bhutan to become modern,but without losing its traditions.
King Wangchuck looked at other countries for ideas.He saw that most countries measured their progress
by their Gross National Product(GNP).The GNP measures products and money. When the number of products
sold increases,people say the country is making progress.King Wangchuck had a different idea for Bhutan.
He wanted to measure his country's progress by people's happiness.If the people's happiness increased,
the king could say that Bhutan was making progress.To decide if people were happier,he created a measure
called Gross National Happiness(GNH).
GNH is based on certain principles that create happiness.People are happier if they have health care,
education,and jobs.They are happier when they live in a healthy,protected environment. They are happier
when they can keep their traditional culture and customs.Finally,people are happier when they have a
good,stable government.
Now there is some evidence of increased GNH in Bhutan.People are healthier and are living longer.
More people are educated and employed.Twenty-five percent of the land has become national parks,and the
country has almost no pollution. The Bhutanese continue to wear their traditional clothing and follow their
ancient Buddhist customs.Bhutan has also become a democracy.In 2008,King Wangchuck gave his power
to his son.Although the country still had a king,it held its first democratic elections that year. Bhutan had
political parties and political candidates for the first time.Finally,Bhutan has connected to the rest of the
world through television and internet.
Bhutan is a symbol for social progress.Many countries are now interested in Bhutan's GNH.These
countries are investigating their own ways to measure happiness.They want to create new policies that take
care of their people,cultures,and land.
Brazil may be the next country to use the principles of GNH.Brazilian leaders see the principles of GNH
as a source of inspiration.Brazil is a large country with a diverse population.If happiness works as a measure
of progress in Brazil,perhaps the rest of the world will follow.
Apart from modernizing Bhutan,what else did Wangchuck want to do for Bhutan?
A:To make its population grow.
B:To keep its traditions and customs.
C:To keep it separate from the world.
D:To encourage its people to get rich.

The Difference between Man and Computer
What makes people different from computer programs?What is the missing element that our theories don't yet1for?The answer is simple:People read newspaper stories for a reason:to learn more about2they are interested in. Computers,on the other hand, don't. In fact,computers don,t3have interests;there is nothing in particular that they are trying to find out when they read. If a computer4is to be a model of story understanding,it should also read for a“purpose”.
of course,people have several goals that do not make5to attribute to computers. One might read a restaurant guide6order to satisfy hunger or entertainment goals,or to 7a good place to go for a business lunch. Computers do not get hungry,and computers do not have business lunches.
However,these physiological and social goals give8to several intellectual or cognitive goals. A goal to satisfy hunger gives rise to goals to find9about the name of a restaurant which10the desired type of food,how expensive the restaurant is,the location of the restaurant,etc. These are goals to11information or knowledge,what we are call-ing12goals. These goals can be held by computers too;a computer13“want”to find out the location of a restaurant,and read a guide in order to do so14the same way as a person might. While such a goal would not15out of hunger in the case of the com-puter,it might well arise out of the“goal” to learn more about restaurants.

Free Statins with Fast Food could Neutralize Heart Risk
Fast food outlets could provide statin drugs free of1so that customers can reduce the heart disease dangers of fatty food,researchers at Imperial College London 2in a new study.
Statins reduce the3of unhealthy“LDL” cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person's heart attack4.
In a paper published in the American Journal of Cardiology,Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is5to offset the increase in heart attack risk from6a cheeseburger and drinking a milkshake.
Dr Francis,from the National Heart and Lung Institute at Imperial College London,who is the senior author of the study,said:“Statins don't cut out all of the7effects of cheeseburgers and French fries. It's better to avoid fatty food altogether. But we've worked out that in terms of your8of having a heart attack. Taking a statin can reduce your risk to more or less the same9 as a fast food meal increases it.”“It's ironic that people are free to take as many unhealthy condi-ments in fast food outlets as they10,but statins,which are beneficial to heart health,have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are 11 free of charge. It would cost less than 5 pence per/u>12一not much different to a sachet of sugar.”Dr Francis said.
When people engage in risky behaviours like driving or smoking,they're encouraged to take13that lower their risk,like14a seatbelt or choosing cigarettes with filters.
Taking a statin is a rational way of15some of the risks of eating a fatty meal.

Eastern Quakes Can Trigger Big Shakes
In the first week of November 2011,people in central Oklahoma experienced more than two dozen earthquakes. The largest,a magnitude 5 .6 quake,shook thousands of fans in a college football stadium,caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV,you see reports about all sorts of natural disasters一 hurricanes,tornadoes,flooding and wildfires,to name a few. But the most dangerous type of natural disaster,and also the most unpredictable,is the earthquake.
Researchers at the U. S. Geological Survey estimate that several million earthquakes rattie the globe each year. That may sound scary,but people don't feel many of the tremors because they happen in remote and unpopulated regions.Many quakes happen under the ocean, and others have a very small magnitude,or shaking intensity.
A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23, 2011,was felt from central Georgia to southeastern Canada. In many urban areas,including Washington,D.C.,and New York City(Wall Street shown),people crowded the streets while engineers inspected buildings.
Scientists know about small,remote quakes only because of very sensitive electronic devices called seismometers.These devices detect and measure the size of ground vibrations
produced by earthquakes.Altogether,USGS researchers use seismometers to identify and locate about 20,000 earthquakes each year.
Although earthquakes can happen anywhere in the world,really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen,on average,only once each year. Such big ones typically occur along the edges of Earth's tectonic plates.
Tectonic plates are huge pieces of Earth's crust,sometimes many kilometers thick. These plates cover our planet's surface like a jigsaw puzzle. Often,jagged edges of these plates temporarily lock together. When plates jostle and scrape past each other,earthquakes occur. On average,tectonic plates move very slowly一about the same speed as your fingernails grow.
But sometimes earthquakes rumble through portions of the landscape far from a plate's edges. Although less expected,these”mid-plate” tremors can do substantial damage. Some of the biggest known examples rattled the eastern half of the United States two centuries ago. Today,scientists are still puzzling over why the quakes occurred and when similar ones might occur.
The earthquake that hit the eastern half of the United States two centuries ago is the biggest“mid-plate” one in history.
