Unless we spend money to spot and prevent asteroids now，one might crash into Earth and destroy life as we know it，say some scientists.
Asteroids are bigger versions of the meteoroids(流星)that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.
Buy $ 50 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one，the scientists say，we'll have a way 
to change its course.
Some scientists favor pushing asteroids off course with nuclear weapo
ns. But the cost wouldn't be cheap. I
s it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare-but if one did fall，it would be the end of the world. “If we don't take care of these big asteroids，they'll take care of us,” says one scientist. “It's that simple.”
The cure，though，might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(毁灭性的) rocks than from a great nuclear fleet set against them，” said a New York Times article. What does the passage say about asteroids and meteoroids?
| A．They are heavenly bodies different in composition. |
| B．They are heavenly bodies similar in nature. |
C．There are more asteroids th an meteoroids. |
| D．Asteroids are more mysterious than meteoroids. |
What do scientists say about the collision of an asteroid with Earth?
| A．It is very unlikely but the danger exists. |
| B．Such a collision might occur once every 25 years. |
| C．Collisions of smaller asteroids with Earth occur more often than expected. |
| D．It's still too early to say whether such a collision might occur. |
What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?
| A．It sounds practical but it may not solve the problem. |
| B．It may create more problems than it might solve. |
| C．It is a waste of money because a collision of asteroids with Earth is very unlikely. |
| D．Further research should be done before it is proved applicable. |
We can conclude from the passage that ________ .
| A．while pushing asteroids off course nuclear weapons would destroy the world |
| B．asteroids racing across the night sky are likely to hit Earth in the near future |
| C．the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime |
| D．workable solutions still have to be found to prevent a collision of asteroids with Earth. |
Which of the following best describes the author's tone in this passage?
| A．Optimistic. | B．Critical. | C．Objective. | D．Subjective. |
Tourism probably started in Roman times.Rich Romans visited friends and family who were working in another part of the Roman empire.But when the empire broke down,this kind of tourism stopped.
In the early 17th century,the idea of the“Grand Tour”was born.Rich young English people sailed across the English Channel（英吉利海峡）.They visited the most beautiful and important European cities of the time,including Paris in France,and Rome and Venice（威尼斯）in Italy.Their tours lasted for two to four years,and the tourists stayed a few weeks or months in each city.The“Grand Tour”was an important part of young people’s education—but only for the rich.
In the 18th century,tourism began to change.For example,people in the UK started to visit some towns,such as Bath to“take the waters”.They believed that the water there was good for their health.So large and expensive hotels were built in these towns.
In the 19th century,travel became much more popular and faster.When the first railways were built in the 1820s,it was easier for people to travel between towns,so they started to go for holidays by the sea.And some started to have holidays in the countryside as cities became larger,noisier and dirtier.
Traveling by sea also became faster and safer when the first steamships were built.People began to travel more to far away countries.
The 20th century saw cars become more and more popular among ordinary people.Planes were made larger,so ticket prices dropped and more people used them.
Thus tourism grew.In 1949,Russian journalist Vladimir Raitz started a company called Horizon Holidays.The company organizes everything—plane tickets,hotel rooms,even food—and tourists pay for it all before they leave home.The package tour and modern tourist industry was born.
The first travel agency in China was set up as early as 1949.But tourism did not take off until 1978.In 2002,the industry was worth 500 billion yuan and became an important part of China’s social development.In the early times,the travelers ________.
| A．all came from Roman |
| B．were very young and strong |
| C．had lots of money |
| D．traveled by boat |
________ played the most important role in the tourism development.
| A．Education | B．Money | C．Transportation | D．People’s ideas |
Modern tourism was born ________.
| A．in 1949 | B．in Roman times |
| C．in the early 17th century | D．in the 19th century |
The underlined phrase“take off”means ________.
| A．a plane rising into the air |
| B．develop very fast |
| C．remove hats and clothes |
| D．bring down the prices |
The twin towns of LAUFEN/OBERNDORF
Laufen owes its former economical and cultural significance to the river Salzach,which forms a peninsula with its sharp curves（弯） there.
Laufen’s economic boom began with the salt trade and the shipping on the river.The salt—mainly coming from Hallein and Bad Reichenhall—was loaded onto bigger ships downstream,which made Laufen one of the most important ports of shipment for salt in Salzburg and Bavaria.
The archbishop（大教主） of Salzburg had given special privileges to the people who were involved in the shipping of salt on the river Salzach.
The Napoleonic Wars brought occupation and serious disturbances.They brought the sudden end to the independent state of the Duke—Archbishop of Salzburg.The end of the 18th century brought a decrease in shipping because of the general economic situation.On the 1st May 1816 Salzburg definitively became a part of Austria （Munich agreement） that’s why the Salzach became the border between Bavaria and Austria.Laufen’s suburbs Oberndorf and Altach were divided up.The number of inhabitants fell from 1392 to 809.Even the re－unification of the two towns’shipsmen’s guilds（行会） and the reorganization of 1928 could not prevent the decline of shipping which finally came to an end in the late 19th century.________played an important role in Laufen’s economy and culture life.
| A．Salt | B．Shipment | C．Guilds | D．Theriver Salzach |
The underlined word“boom”probably means________.
| A．pleasant sounds | B．sudden increase | C．sudden decrease | D．trade |
The main idea of this passage is mainly about ________.
| A．how the economy declined in Laufen |
| B．the effects of The Napoleonic Wars |
| C．how the twin towns of LAUFEN and OBERNDORF came into being |
| D．the history of Salzburg |
Vive la Tower!
Until New York’s Chrysler Building was completed in 1930,the Eiffel Tower was the tallest structure in the world.Located by the river Seine,on an avenue named after its designer,this 985－foot （300－meter） tower is the most famous edifice（大建筑物） in the city of Paris.Gustave Eiffel’s idea was certainly chosen from among 700 proposals（提议） to represent the city in the International Exhibition of Paris in 1889.It commemorated（纪念） the 100th anniversary of the French Revolution. 
In 1887,three hundred steel workers spent two years constructing the 7 000－ton tower.Yet,it was almost torn down two decades after its completion.Luckily,its antenna（天线）,used for telegraphy at the time,saved it.Last July,it looked to observers as though the tower might be destroyed after all,as ominous（不吉利的） black clouds of smoke encircled the structure.Luck was again smiling upon the tower:the fire turned out to be a small one that was quickly put out by attendants on duty.
To date,more than 200 million people have visited the Eiffel Tower.However,it has not always been a beloved tourist attraction.At first,Parisians despised it.Its architectural style and metallic composition were not considered pleasing.Today,the Eiffel Tower is adorned（装饰） with special lights that sparkle for ten minutes each hour,from sunset until one a.m.If you happen to be passing by,look up at this breathtaking monument for an astonishing sight.The Eiffel Tower,composed of iron and steel,is greater than the sum of its parts.If you wanted to see the Eiffel Tower sparkle,when might you stop by?
| A．1:15 a.m. | B．3:30 p.m. | C．9:10 p.m. | D．0:00 a.m. |
When was the Eiffel Tower almost torn down?
| A．1907. | B．1909. | C．1889. | D．2003. |
At first,what did Parisians think about the tower?
| A．The steel and iron parts were unimpressive. |
| B．The awe－inspiring design was attracting. |
| C．Both A and B are correct. |
| D．Neither A nor B is correct. |
The South Pole is a particular place on the earth.When people stand at the top of it looking around,they will find all directions face to north.No matter how they make their first step in which direction,they will always walk towards the north.That’s to say,only north and south exist there,neither east nor west exists.
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.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 |
The Winter Solstice is an important festival ________.
| A．in the world | B．at the South Pole | C．at the North Pole | D．in China |
On the Winter Solstice,________ is the shortest in a year.
| A．the night | B．the noon | C．the morning | D．the daytime |
A HOUSE WITH A HISTORY
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.
