On December 8, Xinhua News Agency published a list of news keywords that it believes sum up the year 2009.

The phrase “low-carbon life” had been heard in China before 2009, but in 2009, it has become popular among young Chinese who are concerned about the environment. It comes as world leaders are talking about fighting global warming in Copenhagen, Denmark. Greenhouse gases, such as carbon dioxide, are the main cause of global warming, which leads to extreme weather and other conditions.

Living a low carbon life means trying to cut carbon dioxide emissions(排放) in one’s daily life. For example, burning less coal and oil, which produce CO2. It means walking, biking or taking buses, rather than using a private car.

“A(H1N1) flu” is also on Xinhua’s list. Since April, 2009 the virus has made over 100,000 people ill on the Chinese mainland and 325 people had died of it as of December 9. But as US magazine Newsweek pointed out recently, the best evidence suggests it is no more dangerous than a bad seasonal flu.

The year 2009 saw the growing impact of the Internet on society, with the word “duomaomao”, meaning hide-and-seek, becoming a hit on the web. On February 12, Li Qiaoming died of brain injuries several days after being detained(拘留) by police in Jinning county, Yunnan Province. Police said it was an accident sustained(遭受)while he was playing hide-and-seek with his fellow prisoners. Netizens cast doubt on this explanation and called for an investigation. It turned out that Li had been beaten to death by other prisoners.

Another phrase connected with the Internet on the list is “Net Addiction Camps”. Many parents send children obsessed(沉迷) with the web to “Net Addiction Camps” for treatment. But some camps use physical punishment or electrical shocks. In 2009, some young people died as a result of the extreme methods, which led to a nationwide discussion. In November, the Ministry of Health banned the use of physical punishment to keep children off the net and dropped the term “net addiction(網癮)”. It did not say that excessive(過度的) net use is a mental illness either.

The purpose of the passage is to ___________.

A. call on the public to live a low-carbon life

B. show the great effect of the Internet

C. introduce some news keywords of the year 2009

D. warn people not to be addicted to the Internet

The underlined word “Netizens” in the fifth paragraph refer to_________.

A. Li’s fellow prisoners

B. Li’s friends and relatives

C. the local people

D. people actively involved in online communities

What can be inferred from the incident of “duomaomao”?

A. Hide-and-seek is a dangerous game.

B. Li was beaten to death by other prisoners.

C. Police did a great job in the investigation (調查).

D. It was the influence of the Internet that led to the truth.

Which of the following is TRUE according to the passage?

A. The phrase “low-carbon life” had been popular among young people before 2009.

B. Global warming mainly results from greenhouse gases.

C. A (H1N1) flu is more dangerous than a bad seasonal flu.

D. Li Qiaoming died of an accident while playing hide-and-seek with his fellow prisoners.

Which of the following doesn’t mean a low-carbon life ?

A. Using a private car.

B. Using efficient light bulbs.

C. Walking, biking or taking buses.

D. Turning your air-conditioner one degree higher.

The Golden Gate Bridge, the first sight for many people arriving in the United States by ship, is a well-recognized landmark, which spans(橫跨) the Golden Gate Strait.

The idea for a bridge across the strait had been around for many years, but it was not easy to get the project started. The construction of the bridge finally began in 1933. The construction work set new standards for safety----workers were among the first required to wear hard hats, and an innovative(革新的) safety net saved the lives of nineteen men while the bridge was built. The Golden Gate Bridge was completed in 1937, which was finished ahead of schedule.

Joseph Strauss was the chief engineer in charge of the bridge project. However, he had little experience with the construction of suspension(懸。゜ridges. For this reason, other engineers, architects, and designers made great contributions to the design and construction of the bridge. For example, the bridge owes its art style and unique orange color to the architects Irving and Gertrude Morrow. Charles Alton Ellis was the main engineer on the project and did much of the technical work necessary to build the bridge.

Today, the Golden Gate Bridge has a main span of 4,200 feet and a total length of 8,981 feet, making it one of the longest bridges in the world. The bridge is 90 feet wide, and its span is 220 feet above the water. The towers supporting the huge cables (巨纜) rise 746 feet above the waters of the Golden Gate Strait, making them 191 feet taller than the Washington Monument. About 40 million cars cross the bridge every year. There are foghorns(霧角)to let passing ships know where the bridge is, and aircraft beacons(信號燈)on the tops of the towers to stop planes from crashing into them.

1.The purpose of the passage is to _______.

A. describe the construction work of the Golden Gate Bridge

B. introduce the Golden Gate Bridge

C. tell us the history of the Golden Gate Bridge

D. introduce the engineers in charge of the Golden Gate Bridge

2.Safety innovations during the construction of the bridge included ________.

A. hardhats and a safety net    B. aircraft beacons

C. foghorns                D. all of the above

3. It can be inferred from the passage that _______.

A. Joseph Strauss was skilled in the construction of suspension bridges

B. it took the construction workers three years to build the Golden Gate Bridge

C. about 100 thousand cars cross the Golden Gate Bridge every day

D. the Golden Gate Bridge is the longest bridge in the world

4.The underlined word “them” in Paragraph 4 refers to ________.

A. towers           B. cables           C. waters          D. bridges
