Passage One
Questions 46 to 50 are based on the following passage.
When is cleaning walls a crime? When you're doing it to create art, obviously. A number of street artists around the world have started expressing themselves through a practice known as reverse graffiti (涂鸦).They find dirty surfaces and paint them with images or messages using cleaning brushes or pressure hoses (高压水管). either way, it's the same principle: the image is made by cleaning away the dirt. Each artist has their own individual style but all artists share a common aim: to draw attention to the pollution in our cities. The UICs Paul Curtis, better known as Moose, operates around Leeds and London and has been commissioned by a number of companies to make reverse graffiti advertisements.
Brazilian artist, Alexandre Orion, turned one of Sao Paulo’s transport tunnels into an amazing wall painting in 2006 by getting rid of the dirt. Made up of a series of white skulls (颅骨)，the painting reminds drivers of the effect their pollution is having on the planet. “Every motorist sits in the comfort of their car, but they don't give any consideration to the price their comfort has for the environment and consequently for themselves,” says Orion.
The anti-pollution message of the reverse graffiti artists confuses city authorities since the main argument against graffiti is that it spoils the appearance of both types of property: public and private. This was what Leeds City Council said about Moose's work: “Leeds residents want to live in clean and attractive neighborhoods. We view this kind of advertising as environmental damage and will take strong action against it.” Moose was ordered to “clean up his act.” How was he supposed to do this: by making all property he had cleaned dirty again?
As for the Brazilian artist’s work, the authorities were annoyed but could find nothing to charge him with. They had no other option but to clean the tunnel—but only the parts Alexandre had already cleaned. The artist merely continued his campaign on the other side. The city officials then decided to take drastic action. They not only cleaned the whole tunnel but every tunnel in Sao Paulo.

答案解析：
46. 由题干中的“reverse graffiti”定位到第一段。第一段提到“They find dirty surfaces and paint them with images or messages using cleaning brushes or pressure hoses. Either way, it's the same principle: the image is made by cleaning away the dirt.”，说明反向涂鸦是通过清理脏墙面来创作图像或传递信息，也就是把脏墙变成艺术作品。所以选D。
47. 由题干中的“reverse graffiti artists try to do”定位到第一段。第一段提到“Each artist has their own individual style but all artists share a common aim: to draw attention to the pollution in our cities.”，说明反向涂鸦艺术家的共同目标是引起人们对城市污染的关注，即提高公众对环境污染的意识。所以选C。
48. 由题干中的“Brazilian artist Alexandre Orion”定位到第二段。第二段提到“Brazilian artist, Alexandre Orion, turned one of Sao Paulo’s transport tunnels into an amazing wall painting in 2006 by getting rid of the dirt.”，说明巴西艺术家Alexandre Orion选择在隧道里进行他的涂鸦艺术创作。所以选B。
49. 由题干中的“Leeds City Council’s decision”定位到第三段。第三段提到利兹市议会要求Moose“clean up his act”，作者反问“How was he supposed to do this: by making all property he had cleaned dirty again?”，说明作者认为利兹市议会的决定很荒谬。所以选A。
50. 由题干中的“Sao Paulo city officials handle Alexandre Orion's reverse graffiti”定位到最后一段。最后一段提到“The city officials then decided to take drastic action. They not only cleaned the whole tunnel but every tunnel in Sao Paulo.”，说明圣保罗市官员不仅清理了整个隧道，还清理了圣保罗的每一个隧道，让Alexandre Orion无法继续创作，也就是使他无法再实践他的艺术。所以选D。
