Foulsham House is a fine,stone house of the 1790s.It stands by the River Byre,in twenty－five hectares（公顷）of the best farmland in the southwest.
Smithson built the house,and the story goes back to George,the young Prince of Wales,who fell in love with the beautiful lady Kitty Wake,at one of the first Lord Foulsham’s wild woods parties.In the past many great men rode on the hills about Foulsham House,and many fine ladies took tea in the Green Room.
The house has eight bedrooms,three bathrooms,two living－rooms and a dining room with a real Adam fire－place（壁炉）.The gentleman’s library has a view over the park and the river.All rooms are light and airy（空气通畅的）,with wood,high windows,and wood floors.
At the back of the house,where the third Lord Foulsham kept the horses,there is garage－space（停车的地方）for four cars.In many other ways,this house of the 1790s meets the needs of the 2000s.
If you wish to know more about Foulsham House,write to:

At the top of the South Pole,any clock or watch keeps good time because all meridians（子午线） join there.All kinds of local time are completely suitable there.It is even difficult to distinguish（区别） New Year’s Eve from New Year’s Day.
The explorers and scientists from different countries always fix the time according to their own.Therefore the time by their watches was different when the people with different nationality gathered there.
The Winter Solstice（冬至日） is an important festival at the South Pole.It is always on June 21 or 22.This day is called Midwinter Festival,on which the daytime is the shortest in a year and the night the longest.All people at the South Pole extend greetings to each other and present gifts to each other.They usually give all kinds of celebrations.From that day on,the daytime will get longer day by day.
小题1:At the top of the South Pole,your watch will ________.
| A．keep good time | B．be five minutes fast |
| C．stop | D．be ten minutes slow |
| A．in the world | B．at the South Pole | C．at the North Pole | D．in China |
| A．the night | B．the noon | C．the morning | D．the daytime |
Whatever the cause of the heat may be,we do know that the earth gets hotter the farther down we dig.In deep mines and oil wells the temperatures rise about 1°F for every 50 feet.At this rate of the temperature 40 miles below the earth’s surface should be over 4 000°.This is much hotter than necessary to melt rock.However,the pressure of the rock above keeps most materials from melting at their usual melting points.Geologists believe that the rock deep in the earth may be plastic,or puttylike（油灰状的）.In other words,the rock yields slowly to pressure but is not liquid.But if some change in the earth’s crust releases the pressure,the rock melts.Then the hot,liquid rock can move up toward the surface.
小题1:The cause for the great heat inside of the earth is______.
| A．great pressure of the earth’s outer layers |
| B．the heat left from the time when the earth was formed |
| C．radioactive elements giving out heat |
| D．not sure |
| A．the pressure of the rock itself |
| B．the pressure of the rock above |
| C．the pressure of the earth’s outer layers |
| D．the heat given out by some radioactive elements |
| A．The farther down,the hotter the earth gets. |
| B．The rock deep in the earth is liquid. |
| C．When the pressure releases from the earth’s crust,the rock melts. |
| D．Rock would be melted at 4 000°. |
On September 29,1998,Hurricane Georges made landfall in Biloxi,Mississippi,after devastating Haiti,the Dominican Republic,Puerto Rico,and several islands of the Caribbean with torrential rains and winds up to 160 km/h （100 mph）.Few people lost their lives along the Gulf Coast of the United States,although hundreds died in the Caribbean.
This was a very different outcome from 1900,when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston,Texas,killing at least 6 000 people.Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century—residents of Galveston had no advance warning that a storm was approaching,while residents of Biloxi had been warned days in advance of Georges’s approach,allowing for extensive safety precautions.
At the same time that people in Biloxi were thankful for the advance warning,some residents of New Orleans,Louisiana,120 km to the west,were less satisfied.A day before Georges made landfall,forecasters were predicting that the hurricane had a good chance of striking New Orleans.Because much of New Orleans lies below sea level,the city is at risk for flooding.In addition,because New Orleans has a large population in vulnerable locations,emergency management officials must begin evacuations well before a storm strikes.But evacuation costs money:Businesses close,tourists leave,and citizens take precautionary measures.The mayor of New Orleans estimated that his city’s preparations for Georges cost more than 50 million.After the full fury of Georges missed New Orleans,some residents questioned the value of the hurricane forecasts in the face of such high costs.
The differing views on the early warnings for Hurricane Georges illustrate some of the complexities involved in predicting disasters.Disaster prediction is more than just forecasting the future with advanced technology—it is also a process of providing scientific information to the government officials and other decision makers who must respond to those predictions.
In general,the process has three phases.First,there is the challenge of forecasting the event itself.In the case of Georges,scientists worked to predict the future direction and strength of the hurricane days in advance.
A second important challenge is communicating the forecast to decision－makers.Because forecasts are always uncertain,a central factor in disaster predictions is communicating this uncertainty.Uncertainty is usually described in terms of odds or probabilities,much like daily weather forecasts.The media plays an important role in communicating predictions and their uncertainty to the public.
The third part of the process is the use of predictive information by decision makers.Even the most accurate information is of little value if the decision maker does not use it appropriately,for example in deciding whether to order an evacuation.If there is a breakdown in any of these three phases of prediction,the result is increased danger and a higher risk of loss of life.
小题1:The underlined word“calamity”refers to ______.
| A．nature | B．thunderstorms | C．disaster | D．dangers |
| A．demonstrate the power of advanced technology |
| B．bring out the truth between life and death |
| C．prevent such natural disasters from happening |
| D．reduce human casualties and loss of property |
| A．Biloxi,Mississippi. | B．Gulf Coast of U. S. |
| C．Galveston,Texas. | D．New Orleans. |
The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2 000 years.It began in the rule of China’s first emperor,Qin Shihuang of the Qin Dynasty (221 BC～206 BC),and lasted into the Ming Dynasty.The parts built before the Ming Dynasty have nearly disappeared.People are familiar with sections such as Badaling in Beijing and Jiayuguan Pass in Gansu because they have been open to tourists for many years.But those sections far away from the public eyes have been almost forgotten.
Few local people knew the 3-meter-high walls made of earth and stones beside them are part of the Great Wall.The lack of knowledge is considered as one of the main reasons behind human.
The bricks on the Great Wall are carried off by countryside people to build their houses,sheep corral(畜栏) and pigsties(猪圈).Some were taken away to build roads.Bricks carved with people’s names are put away as remembrance.Rubbish is spread over the battlements(城垛).The bricks can be sold for 15 yuan per tractor load.Those who destroyed and are destroying the Great Wall know its name,but are not clear about its cultural meaning.It will take a long time to let them know this.The local farmers not only carried off the body of the Wall but dug out the entire base.
It is necessary to protect the Great Wall.First of all,the officials should be aware of theimportance of the Great Wall.Young Chinese should know more about the nation’s great civilization (文明)and learn to love it.
小题1:The main reason for which the Great Wall can be called“great”is__________.
| A．it was made by brick | B．it was very wide |
| C．it was very long | D．it had a long history |
| A．It is useless from now on. | B．It will be replaced by a new one. |
| C．Some parts of it are being destroyed. | D．It’s too old to be used again. |
| A．that are too difficult to understand | B．nobody can watch |
| C．that are too far to been seen | D．that are not well known to the public |
| A．The local people are short of culture knowledge. |
| B．The local people need bricks and stones to build houses. |
| C．The local people think that the Great Wall is not important. |
| D．The local people are against the government. |
