However, bridge building experts throughout the world thought this was an impossible feat and told Roebling to forget the idea, but Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he managed to convince his son Washington, an up and coming engineer, that the bridge in fact could be built. The project started well, but when it was only a few months underway a tragic accident on the site took the life of John Roebling. Washington was injured and left with a certain amount of brain damage, which resulted in him not being able to walk or talk or even move. "We told them so." "Crazy men and their crazy dreams.'' "It's foolish to chase wild visions." Evcryone had a negative comment to make and felt that the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap, Washington was never discouraged. One day he was lying on his bed in hospital, seeing the sky and the tops of the trees outside for just a moment with the sunlight streaming through the windows, and a gentle breeze bowing the flimsy white curtains apart when an idea hit him. He decided to make the best use of the only finger he could move. Thus, he slowly developed a code of communication with his wife. He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. It seemed foolish but the project was under way again. For 13 years Washington tapped out his instructions with his finger on his wife's arm until the bridge was finally completed. Question: From the passage, we know that _ when Roebling proposed building the bridge. Options: A: people all over America supported him B: almost no bridge experts in the world supported him C: his friends were strongly in favor of his idea D: many people considered it would be a great fe

The airplane was built using only a computer--but it can fly at a speed of 100mph and has a two-meter wingspan. It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a "snap fit" technique so the aircraft could be put together without tools in minutes. No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as "laser sintering "and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost. Professor Jim Scanlon, who led the team, said, "The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing." He added, "This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense." The new printed plane is known as the Southampton University Laser Sintered Aircraft--or SULSA for short--and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s. Question: How could the plane work while flying? Options: A: It should be controlled by an autopilot system. B: It should be controlled by "laser sintering". C: A pilot controls it using a remote control. D: A pilot with high techniques controlled it.

Q: Read the article and select the best answer. Article: MUMBAI, India --The children in their party clothes on the stage were very excited when they received the award. And the two of them said, "It's unbelievable!" Nine-year-old, Rubina Ali, and Azharuddin Ismail, 10, were living a very different life and obviously loving every minute of it. The two, some of the child stars of the Oscar-winning Slum dog Millionaire(<<>> )movie, know the Indian slums very well. That was where they grew up, and it is where they will return at the end of their Hollywood dream trip. But before going back home, there was an interview with the host, Ryan Seacrest. During the interview they smiled and repeated their disbelief in what was happening to them. To their surprise, their movie won first place in the Oscars. When the two received the award, it was late morning in the children's home city of Mumbai, where family, friends and many fellow residents of the slums watched the result from Hollywood. "I don't really know what the Oscars are," Rubina's mother said. "I'm just glad my daughter looks happy, though she told me she missed Indian food." "Our children lead a dog's life," Rubina's mother said, pointing out the rubbish everywhere, the open drains and the lack of education opportunities. In a few days they will be back in Mumbai and back in the slums which are their home. Fortunately, according to media reports, the movie's director, Danny Boyle, has promised to help the children chosen from the slum and make sure they will go to a proper school. The two don't need to worry about their daily lives because of the Oscar success of Slum dog Millionaire. But the poverty and lack of opportunity --the central theme of the movie--is always all around. Question: According to the author, the value of the movie is that _ . Options: A: it has been given an Oscar Award B: it has made the two children famous C: its central theme has become known to the public D: it has become popular all over the world
A: C

*Question*
Read the article and select the best answer. Article: Through a series of experiments an American scientist has gained an understanding of the social structure of the most complex of ant societies. The ants examined are the only creatures other than man to have given up hunting and collecting for a completely agricultural way of life. In their underground nests they cultivate gardens on soil made from finely chopped leaves. This is a complex operation requiring considerable division of labour. The workers of this type of ants can be divided into four groups according to the size. Each of the groups performs a particular set of jobs. The making and care of the gardens and the nursing of the young ants are done by the smallest workers. Slightly larger workers are responsible for chopping up leaves to make them suitable for use in the gardens and for cleaning the nest. A third group of still larger ants do the construction work and collect fresh leaves from outside the nest. The largest are the soldier ants, responsible for defending the nest. To find out how good the various size-groups are at different tasks, the scientist measured the amount of work done by the ants against the amount of energy they used. He examined first the gathering and carrying of leaves. He selected one of the size-groups, and then measured how efficiently these ants could find leaves and run back to the nest. Then he repeated the experiment for each of the other size-groups. In this way he could see whether any group could do the job more efficiently than the group normally undertaking it. The intermediate-sized ants that normally perform this task proved to be the most efficient for their energy costs, but when the scientist examined the whole set of jobs performed by each group of ants it appeared that some sizes of worker ant were not ideally suited to the particular jobs they performed. Question: It seems that smaller ants perform more of the _ . Options: A: construction tasks B: home tasks C: defensive work D: heavy work
**Answer**
B
