【原文】The Temple of Heaven is situated in the southern part of Beijing, about 6 kilometres away from the centre of the city. Traditionally, this temple 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 emperor left the Forbidden City through the front gate for the Temple of Heaven. No common people or foreigners were allowed to watch the emperor s procession to the temple. They had to remain hidden behind closed doors and windows. No women, not even the empress, were allowed to take part in the procession.

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 the city and surrounding countryside. There is also a glass-enclosed observatory on the 102nd floor.
Task 3:

【原文】
Janet Owens' house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000, three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with double-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.
