习题精选系列答案The Chinese word"Shanzhai" means a small mountain village， but now it becomes an accepted name for fakes(假货) after" Shanzhai cell phones " produced by small workshops in southern China ，became popular in the mainland market over the past few years.
Besides" Shanzhai" electronic products， there are "Shanzhai" movies， "Shanzhai" stars and even a "Shanzhai" Spring Festival Gala， a copy of the 25-year-old traditional show presented by CCTV on Chinese Lunar New Year's Eve.
" Shanzhai" has become a culture of its own，symbolizing anything that imitates something famous.
The phenomenon has caused a public debate over whether it is healthy or sick being a copycat.
In southwestern China's Chongqing Municipality，a "Shanzhai" -version"Bird’s Nest" woven by farmers with bamboo attracts wide attention and the"Shanzhai"-version "Water Cube"is popular with tourists too. Both are copies of the famous Olympics buildings in Beijing.
Xie Xizhang，a literature critic，said that taking the "Shanzhai" Gala as an example， when the traditional CCTV program becomes less and less attractive to the audience， the "Shanzhai" version appears naturally to attract people.
"In spite of its poor techniques and operation， ‘Shanzhai’ culture meets the psychological demands of common people and could be a comfort to their minds," Xie said.
Tian Huiqun，a professor at Beijing Normal University，said that "Shanzhai" culture never copies classic things，only trendy products. In that sense，it's like a computer virus， multiplying without meaning.
Though controversial，"Shanzhai" culture is becoming a widely accepted phenomenon.
"To the mainstream culture, the rise of ‘Shanzhai' culture is a challenge as well as a motivation，" said Xie.
Tian said different kinds of cultures developing together is an ideal situation and it is for the public to choose.

Eat, drink and be merry. That’s what Spring Festival is all about. But there are millions of people, too, who love to let happiness go up in smoke.Offering cigarettes to guests is a traditional Chinese way of showing respect to them. A cup of tea and cigarettes are perhaps the most common way of welcoming a guest in China, especially during festive occasions.No wonder, 40 percent of the people surveyed(调查) recently said they would smoke at least twice the usual number of cigarettes during the Spring Festival because of all those gatherings and parties. Only 20 percent of the respondents said they would refuse a cigarette when offered one. Why can’t the others do the same? Because they could be seen as being rude, said more than half in the respondents. 15 percent feared they could be taken as “someone who cannot get along well with others”.The Think-tank Research Centre for Health Development and sohu. com survey shows 61 percent Chinese think offering a cigarette is useful for socialising, and 52 percent have offered cigarettes to others. The study surveyed 3,800 people, and 64 percent of them were men.One-third of those surveyed were smokers, out of which 57 percent said they couldn’t give up smoking because of the offering-and-accepting culture. “People have accepted offering cigarettes as an effective way of making friends,” research centre director Wu Yiqun says.China has more than 350 million smokers, catering to the tobacco market that is worth 500 billion yuan. “The survey shows we still have a lot of work to do,” Wu says. “It is time to let people know that offering a cigarette is a bad habit and it should be given up immediately.”

The Beginning of the Civil Rights Movement
In 1955，bus seats for African Americans and whites were separated in parts of the U．S.. On December 1,1955，in the city of Montgomery，Alabama，a conflict，or disagreement，started when an African American woman named Rosa Parks refused to give her bus seat to a white man and go to the back of the bus. The police took 42yearold Parks to jail.
The African American community was extremely angry. They had a meeting and decided to work together to protest discrimination. They agreed to boycott(抵制) the buses on the day that Parks went to court. The day was a success. Empty buses drove through the streets. The city lost money. The community decided to continue the boycott. They elected a man named Martin Luther King，Jr. to be the leader.
The boycott continued. It was difficult for African Americans to get to work without buses，but they didn’t stop the boycott. The city continued to lose money. Finally，the U．S. Supreme Court decided that Montgomery’s bus laws were unfair and gave the African American community equal right. On December 21,1956，the bus boycott ended.
The Montgomery Bus Boycott was the beginning of the Civil Rights Movement. The movement eventually led to the Civil Rights Act in 1964，a set of laws that made discrimination a crime. During the Montgomery Bus Boycott，people worked together to change the government. Today，people in the U．S. continue to work together for a change. Now hundreds of organizations and community groups work to protect the rights of U．S. citizens and residents.
