Futurologists predict that life will probably be very different in 2050 in all the fields of activity, from entertainment to technology. First of all, it seems that TV channels will have disappeared by 2050. Instead, people will choose a programme from a menu and a computer will send the programme directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programmes, newspapers and books will come to us by computer. In what concerns the environment, water will have become one of our most serious problems. In many places, agriculture is changing and they are growing fruit and vegetables to export. This uses a lot of water. Demand for water will increase ten times between now and 2050 and there could be serious shortages. Some futurologists predict that water could be the cause of war if we don't act now. In transport, cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed of the car and there won't be any accidents. Today, many cars have computers that tell the drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. On the other hand, space planes will take people half way around the world in two hours. Nowadays, the United States Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angels to Tokyo in just two hours. In the field of technology, robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots -- they do not ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere -- in factories, schools, offices, hospitals, shops and homes. In particular, medicine technology will have... Question: . _ is the main factor that makes driving much safe in the future Options: A: Good traffic condition B: A good knowledge of driving skill C: The role played by computer D: The use of new fuel in cars

Researchers say the find gives new light on the Amazon's history - and show it was a savannah rather than the high forest it is today. They believe much of the area was grassland until a natural shift to a wetter climate about 2,000 years ago let the rainforests form, according to a study that challenges common belief that the world's biggest tropical forest is far older. The arrival of European diseases after Columbus crossed the Atlantic in 1492 may also have sped up the growth of forests by killing the local people farming the region, the scientists wrote in the US journal Proceedings of the National Academy of Sciences (PNAS). "The dominant ecosystem was more like a savannah than the rainforest we see today," John Carson, lead author at the University of Reading in England, said of the findings about the southern Amazon. The scientists said that a shift toward wetter conditions, perhaps caused by natural shifts in the Earth's orbit around the sun, led to growth of more trees starting about 2,000 years ago. The "findings suggest that rather than being rainforest hunter-gatherers, or large-scale forest clearers, the people of the Amazon from 2,500 to 500 years ago were farmers," the University of Reading said in a statement. Carson said that perhaps a fifth of the Amazon basin, in the south, may have been savannah until the shift, with forests covering the rest. In one lake, Laguna Granja, rainforest plants only took over from grass as the main sources of sediments about 500 years old, suggesting a link to the arrival of Europeans. And understanding the forest could help solve puzzles about climate change. The Amazon rainforest affects climate change because trees soak up heat-trapping carbon dioxide as they grow and release it when they rot or are burnt. Brazil has sharply slowed deforestation rates in recent years. Question: How does the author think about Columbus' crossing the Atlantic in 1492? Options: A: Significant. B: Necessary. C: Valueless. D: Destructive.

Read the article and select the best answer. Article: Removing the sleeve , you will find a book that is entirely white, except for the names of its author and subject in elegant black type on the cover. It is the perfect design for the biography of a man who insisted that even the insides of his products be perfectly constructed, and that his factory wails flash in the whitest white. The cover was the only part of the book Steve Jobs wanted to control, writes Isaacson in his introduction. Though Mr. Jobs pushed the biographer of Albert Einstein and Benjamin Franklin to write in his own way, generously allowing the writer more than 40 interviews, this book offers quite a different view of Mr. Jobs, who won much praise from his fans after his death on October 5th at the age of 56. As a biographer of Albert Einstein and Benjamin Franklin, Mr. Isaacson knows how to celebrate long-dead genius, but he claimed that "Steve Jobs" would not be entirely praiseful words. The picture he paints, particularly in the first half of this book, is not nice. Mr. Jobs emerges as a controlling and often cold-blooded character. A child of the 1960s counter-culture , he hated, materialism and lived in simply furnished houses ( in part because he was too particular about furniture). But when Apple went public in 1980, he refused to give any share to Daniel Kottke, a Iongtime supporter and soul mate from college. "He has to abandon the people he is close to," observes Andy Hertzfeld, an early Apple engineer. Mr. Jobs was undoubtedly possessing an extraordinary ability to attract others and inspire a kind of faith that could not be questioned. But also he could be cold and cruel. If he disapproved of an employee's work, he often shamed him. "This is who I am," he once said after being challenged,"and you can't expect me to be someone I'm not. " This disgusting personality wasn't always helpful,but it served a purpose, writes Mr. Isaacson, many would "end their chain of horror stories by saying that he got them to do things they never dreamed possible. " Mr. Isaacson treats "Steve Jobs"... Question: The biography for Jobs is believed to have the perfect design because _ Options: A: it follows Jobs' style B: its cover is entirely white C: black and white are his favorite . D: it is designed by a famous biographer
