What is art? That's an easy question to answer. Art is a painting, a drawing or a sculpture. Now there are new items to add to the list. Art is a dead shark in a glass case. Art is an unmade bed. Art is a video of a group of people standing completely still for sixty minutes. A new group of young artists began to produce work that challenged the accepted idea of what art is and the role the artist should play in society. This group came to be known as the YBAs—the Young British Artists. The art of the YBAs does not just stick to painting and sculpture. It uses all kinds of different materials to express the feeling of the artist. Damien Hirst is the most famous of the YBAs. The shark in the box is his work and is meant to express his own fear of dying. The shark stands for death. Right now, it is harmless. But eventually it will come for you. There is nothing to be done about it. Traditionally, artists have a message. They use their skills to lead us to enlightenment (启迪). The message of the YBAs is that they cannot do this. They are just as mixed up and confused as everybody else. A journalist once asked Damien Hirst what his next idea was for an artwork. “I don't know what I'm going to do next. I never know what I'm going to do next,” he replied. Another YBA, Tracy Emin recently produced a work called “Bed”. This is just her own bed with the sheets disarranged and dirty. And the message? “Look at me—I'm a mess.” Some artists work with the public in producing their work. Gillian Wearing filmed a group of people dressed as policemen trying to keep still for 60 minutes while standing on top of a table. At the end of that time, the table falls apart and everyone falls to the floor. You can try to be a good citizen and a respectable member of the community. But don't try too hard or the pressure will be too much. Art mirrors the state of society. In the work of the YBAs we can see a society on the threshold (开端) of the future—a bit worried, a bit excited and wondering what is going to happen next. The YBAs can't guide us, but they can make the journey more interesting.【小题1】What does the underlined word “it” in Paragraph 3 refer to?A．The shark.B．Death.C．Damien's artwork.D．Damien's fear of dying.【小题2】What can be inferred from Tracy's work “Bed”？A．She needs to be taken care of.B．She sees the world as a dirty one.C．She compares herself to the bed.D．She hopes for better living conditions.【小题3】Which of the following refers to a person who tries too hard in Gillian's work?A．The table.B．The floor.C．60 minutes.D．The people dressed as policemen.【小题4】What is the main purpose of the text?A．To explain what the work of the YBAs is like.B．To show how the YBAs form ideas for their work.C．To describe the YBAs as artists full of imagination.D．To show the YBAs have made a great difference in art.
