A Hollywood movie was met with an awkward situation last Saturday in China. While fans are standing in long queues to watch the first show, others are advocating a boycott(抵制)on the American movie with Chinese story elements.

  After "Kung Fu Panda", a cartoon movie telling about a panda’s Kung Fu master journey, hit China’s silver screens in 2008, its sequel (续集), Kung Fu Panda 2, was released in China just ahead of International Children’s Day, adding more Chinese elements such as shadow play (皮影戏) and lion dancing.

  However, some Chinese artists and scholars argue that the movie has twisted (扭曲) Chinese culture and serves as a tool to "kidnap (绑架)" the mind of the Chinese people.

  “Children’s Day should be pure. Don’t turn it into a money-making day for Hollywood, and don’ t fool our next generation with American fast food,” according to an open letter to Chinese cinema managers written by Zhao Bandi, an artist hoping to boycott the “Americanized” movie. His move is backed by Kong Qingdong, a professor of the Chinese language in Beijing University, who said Chinese elements have become advertising products to advocate American culture. "It is a cultural invasion," said Kong.

  In the movie, the main character called “Po,” a panda, is talkative, humorous, lovely, and is widely believed to be a typical American figure.

  However, the panda has won millions of fans in China. On China’s most popular website, comments on the movie reached nearly 270 million entries.

  “I won’t call it a cultural invasion,” said Li Jiayi, a Beijing university student. “I see nothing bad for others to use our cultural elements to make a movie. I’ m a huge fan of Po. In spite of being a cartoon, it is still loved by many adults like me,” said the 25-year-old after watching the first show at midnight.

  Cao Hui, general manager of Shenzhen Global Digital Creations company, said: “instead of a

‘boycott’, movie producers should learn from the movie to make better use of Chinese story elements. Technically, Kung Fu Panda is not more advanced than Chinese movies, but as for story telling skills, Chinese movies have a long way to go”.

小题1:Some artists and scholars are against "Kung Fu Panda" because they think_____.

C.it is an exact copy of Chinese culture

D.it is advertising American culture小题2:What does the underlined word “backed” in the fourth paragraph mean?

发达国家中冠心病的发病率是发展中国家的将近3倍。有人认为,这要归咎于发达国家中人们的高脂肪、高蛋白、高热量的食物摄入。相对来说,发展中国家较少有人具备条件生这种富贵病。其实,这种看法很难成立。因为它忽略了这样一个事实:目前发达国家的人均寿命高于70岁,而发展中国家则不到50岁。
以下哪项如果为真,最能加强上述反驳?()

A.一般地说,一个人的寿命越长,在其有生之年患有某种疾病的概率越高。

B.统计资料显示,冠心病患者相对集中在中老年年龄段,即45岁以上。

C.目前冠心病患者呈年轻化趋势。

D.发展中国家人们的高脂肪、高蛋白、高热量食物的摄入量,无论是总量还是人均量,都在逐年增长。

E.发展中国家冠心病的防治水平近年有显明提高。
