was for imperial use only It was built in 1420 covering an area of 273 hectares It is one of the largest parks in Beijing The Temple of Heaven was the place where the emperors of the Ming and Qing dynasties worshipped heaven and prayed for good harvests The emperors visited the temple three times a year on the 8th day of the first lunar month to pray for a good harvest during the Summer Solstice to pray for rain and during Winter Solstice to give thanks for a good harvest During each ceremony the emperors worshipped heaven and prayed for a good harvest In addition the emperors also worshipped their ancestors and other natural phenomena such as the Cloud God Rain God and Wind God In imperial days the Chinese people believed that the sky was circular and the earth was square On the basis of this traditional concept the circle was widely adopted in the design of the temple s main building It is in accord with people s imagination of heaven During past ceremonies each year the

1 F 2 F 3 T 4 T 原文原文 Until the construction of the Sears tower in Chicago and the World Trade Center in lower Manhattan which unfortunately collapsed in a terrorist attack on September 11 2001 the Empire State Building was for 40 years the tallest building in the world standing 102 stories and 1 454 feet tall including a 222 feet television antenna The unusual structure of the Empire State Building built in just 410 days during the depths of the Depression was planned during the boom years of the 1920s and completed in May 1931 The building cost 40 000 000 dollars and was the product of a competition between Walter Chrysler Corporation and John Jakob Raskob founder of General Motors to see who could build the tallest building The structure itself weighs 365 000 tons less than the weight of the earth that was dug out to build it Time has shown it to be durable but when it was first opened to the world the public was worried about the stability of what was then the tallest building ever seen A number of curious events have contributed to this famous building including that an Army Air Corps B 25 bomber plane crashed into the 79th floor on a foggy day in July 1945 at the end of World War II killing 14 people The television antenna was added in 1951 The top 32 floors of the building are lit at night There is an observatory on 86th floor which gives a 50 mile view of

glazed windows and several other energy saving qualities Problems began as soon as the couple moved in however Janet s eyes burned Her throat was often dry She suffered from headaches and could hardly sleep It was as though she had suddenly developed a strange illness Experts finally found the cause of her illness The level of formaldehyde gas in her kitchen was twice the largest amount allowed by federal standards for chemical workers The source of the gas Her new kitchen cabinet and wall to wall carpeting The Owens suffered the effects of indoor air pollution which is not given enough attention partly because of the nation s drive to save energy The problem itself isn t new It appears to be more troublesome in newly constructed homes rather than old ones Back in the days when energy was cheap home builders didn t worry about unsealed cracks Because of such leaks the air in an average home was replaced by fresh outdoor air about once an hour As a result the pollutants caused by most households seldom built up to dangerous levels Task 4 答案答案 A 1 several thousand 2 700 years ago 3 An 36 meter wide road An 18 meter wide one 9 meters 10 meters 40 centimeters B 1 T 2 T 3 T 4 F 原文原文 For those who want to experience the local customs as well as the history and culture of Beijing they must visit the hutong and siheyuan courtyard house A hutong is an alley or lane typical in the old city of Beijing where hutongs run into the several thousand Surrounding the Forbidden City many of the hutongs were built during the Yuan Ming and Qing dynasties In these dynasties the emperors had the city planned and arranged according t the etiquette systems with the royal palace the Forbidden City standing in the center The word hutong originally came from the Mongolian language about 700 years ago and meant water well that is a place where there was a spring or well fit for people to live Hutong is in fact the passage formed by lines of siheyuan courtyard houses where most Beijing residents used to live One hutong connects with another and siheyuans connect with siheyuans to form a block and blocks join with blocks to form the whole city In old China there was a clear definition for a hutong A 36 meter wide road was called a big street An 18 meter wide one was called a small street Only a lane less than 9 meters wide was called a hutong The shortest hutong is just 10 meters long and the narrowest hutong is only about 40 centimeters wide Most of the hutongs in Beijing run from the east to the west or from the north to the south That has resulted from the need for houses to take in more sunshine There are many stories and fairy tales about the hutongs Near the Forbidden City for example there is a hutong called Weaving Girl which is named after the fairy from the famous Chinese myth who stole out of the Heavenly Palace to come to the earth and fell in love with a shepherd boy Her enraged father the Celestial Emperor seized the girl back and separated the couple with the Milky Way permitting them to meet only once a year on the 7th day of the 7th lunar month when magpies form a bridge for them to pass over the barrier In the life of the people in Beijing the hutong has a very special and important position It is more than a style of architecture It is really the encyclopedia of the history and culture of Beijing Task 5 答案答案 A

world visit the white stone structure every year The monument is a structure called an obelisk Its four sides end in a point at the top Fifty American flags surround it They represent the fifty states Lights shine on the Washington Monument at night It can be seen from far away Fireworks are launched from near the monument on American Independence Day July fourth and at other special celebrations It took many years to build the Washington Monument One group started raising money for a memorial in 1833 Officials placed the first stone of the monument on July fourth 1848 Roman Catholic Church leader Pope Pius the Ninth gave a piece of marble from Rome for the monument But the stone was stolen in 1854 After that the public almost stopped giving money for the structure Many people believed it would never be finished A group called the Know Nothings was suspected of trying to stop the monument from being built Finally in 1876 Congress voted to pay for building the Washington Monument It was finished in 1884 and opened to the public in 1888 The Washington Monument recently re opened after being closed for more than a year Officials used that time to make improvements New security measures also were added And a new elevator now carries visitors to the observation area on top of the monument From there visitors can look out over the capital city Task 6 答案答案 I A city council C

can be attached to excavators A heavy steel ball is swung on the end of a cable to knock down old buildings Mechanical shovels and grabs scoop up loose earth and rubble and drop it into trucks Skyscrapers are very heavy They need strong ground to support their weight They can be built on solid rock but ordinary soil is much too weak Strong supports called foundations have to be built in the soil First the builders bore into the ground They take soil from different depths They test the soil to see if it is strong or weak If the soil is strong the builders may use a big concrete slab for the foundations They dig a deep hole with powerful excavators The excavators have scoops or shovels that remove the soil in great bites When the hole has been dug tons and tons of concrete are poured into it for the foundations If the soil is weak piles are used for the foundations Piles are thick pillars of concrete and steel They reach from the surface down to rock or firm soil Sometimes holes are bored in the ground and then filled with concrete Sometimes the piles are made on the surface Then they are driven deep into the ground with powerful hammers called pile drivers When the concrete foundations have set the frame is made of strong steel girders Sometimes it is made of reinforced concrete Steel bars are put in place first and are boxed in Then concrete is poured around them The concrete sets and makes a very strong frame Huge cranes lift the girders or the steel bars into place as the building grows They carry up wet concrete in big buckets called skips The cranes are called tower cranes because they stand on tall steel towers At the top they have a long arm that swings around in a wide circle to deliver the building materials When the frame of each level or storey is finished the builders can put in the floors First they put up a frame of boards around the floor area Then they pour concrete into it The vibrator makes the concrete firm and helps to settle it The walls can be made in the same way But often they are made of glass or metal They can be thin because they do not have to bear any weight The weight of the building is carried by the framework of concrete or steel girders Walls which do not bear the weight of a building are called curtain walls Ordinary building methods are quite slow The builders have to wait for the concrete to set in one part before they can move on It is quicker to use ready made panels for the walls and floors The panels are brought to site lifted into place and then joined together The skyscraper must also have services put in The telephone company puts in telephones Electricians wire up the rooms for electricity Plumbers fit th6 water pipes Heating engineers put in the heating system Other engineers put in the elevators Elevators are important in skyscrapers In ordinary houses there are not many stairs but in skyscrapers there are hundreds and hundreds An other problem is cleaning the windows The window cleaners cannot work from ladders on the ground They have to work from a scaffold that dangles from the roof The day arrives when the skyscraper is completely finished from top to bottom The scaffolding is taken away The builders remove their cranes and concrete mixers and trucks The movers arrive to move in the furniture Curtains are hung and carpets are laid The electricity and heating are turned on Then at last all is ready for the people to move in Task 7 答案答案 A 1 c 2 c 3 a 4 a 5 b 6 b B 1 F 2 T 3 T 4 F 5 T 6 F 7 T 原文原文 Interviewer What is a home in your understanding Rybczynski A home represents a refuge from the public world It is a safe place in which people feel that they can let their minds drift off and dream Imagining a house building it and then living inside it is something quite wonderful Every time you enter that house you re really entering your own mind This is equally true whether you are an architect or somebody living in a Mexican slum An awful lot of what people do with their homes can t be explained by simple function it has as much to do with communicating an idea of themselves to others In some countries even the smallest shacks are constructed
