He lived his whole life as a poor man. His art and talent were recognized by almost no one. He suffered from a mental(精神的)illness that led him to cut off part of his left ear in 1888 and to shoot himself two years later. But after his death, he achieved world fame. Today, Dutch artist Vincent van Gogh is recognized as one of
the leading artists of all time.
  Now, 150 years after his birth on March 30, 1853, Zundert, the town of his birth, has made 2003 “The van Gogh Year”in his honor. And the van Gogh Museum in Amsterdam, home to the biggest collection of his masterpieces, is marking the anniversary(周年纪念)with exhibitions throughout the year. The museum draws around 1.3 million visitors every year. Some people enjoy the art and then learn about his life. Others are first interested in his life, which then helps them understand his art.
Van Gogh was the son of a pastor(牧师). He left school when he was just 15. By the age of 27, he had already tried many jobs including an art gallery(画廊)salesman and a French teacher. Finally in 1880, he decided to begin his studies in art.
Van Gogh is famed for his ability to put his own emotions into his paintings and show his feelings about a scene. His style is marked by short, broad brush strokes(笔画).“Instead of trying to reproduce exactly what I have before my eyes, I use color more freely, in order to express myself more forcibly,” he wrote in a letter to his brother in 1888.
Van Gogh sold only one painting during his short life. He relied heavily on the support from his brother, an art dealer who lived in Paris. But now his works are sold for millions of dollars. His portrait of Dr. Gacher sold for $89.5 million in 1990. It is the highest price ever paid for a painting. “I think his paintings are powerful and the brilliant colors in them are attractive to people,” said a Van Gogh’s fan.
【小题1】All through his life, Van Gogh __________.
A.depended on his brotherB.worked hard on art studies
C.was not recognized by people D.expressed himself in paintings
【小题2】 Van Gogh killed himself because of ___________.
A.the poor lifeB.his illness
C.his pain from left earD.the objections from the artists of his time
【小题3】 One of the characteristics of Van Gogh’s paintings is ______________.
A.the likeness between his paintings and the reality
B.the short time for him to complete a painting
C.the various styles mixed together
D.the special strokes he made
【小题4】 The selling of his paintings is considered to be the most successful because ________.
A.more and more people like his paintings
B.people can understand him through his paintings
C.1.3 million people visit his painting museum every year
D.Zundert has made 2003 “The Van Gogh Year” in his honor
【小题5】 We can infer from the passage that _______.
A.his powerful art came from his poor life
B.his fellow townsmen regret treating him unfairly
C.all his paintings were drawn in the last 10 years of his life
D.most of his paintings are kept in the museum of his hometown
