Read the following article and select the best answer. Article: In 1812, in a village near Paris, France, a little boy had a terrible accident. He hit himself in the eye with one of his father's sharp tools, and became blind. His name was Louis Braille, and he was only four years old. He was a clever little boy, and he soon learned to "see" without his eyes. He touched things, or smelled them, or tasted them. His family described things to him. Although he couldn't see people's faces, he learned to recognize their voices. After his seventh birthday, Louis went to the little school in the village. But there weren't any books for him. His classmates read his lessons to him and his sisters helped him with his homework. He learned his lessons well, but he couldn't learn to read or write. In 1819, the village priest   told Louis Braille's story to the director of a famous school for blind boys. At this school, boys learned math, grammar, geography, history, and music. And they learned to read! Louis went to the school in Paris in February, 1819. He loved his classes and received high grades. He learned to play the piano and to knit   hats and sweaters. And he learned to read -- with his fingers! The raised-print letters in the books at school stood up from the surface of the paper. Louis could feel them with his fingers. He was able to recognize some of them easily, but some of them were difficult. The letters had to be very large, and sometimes there were only a few letters on a page. The books were huge and heavy. And they were expensive. There were only fourteen books in the school library! Louis read the three or four books for his class again and again. He tried to think of a better way to make books for blind people. He experimented with new alphabets. After about three years, Louis invented a system of raised dots. The other students thought Louis's system was wonderful. They were able to read it easily, and they learned to write, too. Today, there are thousands of Braille books for blind people. Louis Braille was only fifteen years old when he invented his wonderful system! Question: Without his eyes, he could also "see" by   _   . - touching things - smelling or tasting things - trying to recognize people's voices - all the above ways
(Answer)
all the above ways

Read the following article and select the best answer. Article: A small town in Tasmania, an island off the south coast of mainland Australia, is making itself an environmental role model by becoming the country's first plastic bag-free town. Since April 28, Coles Bay's population of 175 and its tourist shoppers have been using reusable paper or cloth bags to carry their shopping. Ben Keamey, a local businessman who supports the bag ban, said it would cut  the amount of waste and prevent damage to native wildlife that try to eat the plastic. "Most businesses here come from the tourism and that's all based on the environment, so people were pretty supportive," he said. Every year Australians use more than six billion plastic bags. More than half of these come from the supermarket. Since it takes years for the bags to biodegrade , tens of millions end up polluting the environment. They kill about 100,000 sea-birds and animals, which mistake bags for food, every year. Only in the past few months have major Australian supermarkets begun cutting on their use of plastic bags. Environmental groups are pushing for a plastic bag fee like that in Ireland. There, since plastic bags cost 10 pence (about 1 yuan) each, their use has been cut by 90 per cent. Pollution caused by plastic bags is a big headache for countries all over the world. As early as 1999, Beijing said that only plastic bags of certain thickness could be used. This was to encourage them to be used again and again, since an average of six million plastic bags are used there every there every single day. Question: Plastic bags will not be used by the native people of Coles Bay because they   _  . - cause the environmental pollution - are not easy to be reused - are not as good as cloth bags - are not strong enough
(Answer)
cause the environmental pollution

Read the following article and select the best answer. Article: Monkeys , face to face DISCOVER magazine once reported on a curious event in the woods : a group of monkeys applied mud   to their faces in order to keep away insects , but when they were done they seemed to have lost their ability to recognize each other ---two monkeys that were supposed to be friends even started fighting. "Faces are really important to how monkeys and apes  can tell one another apart," explained Michael Alfaro, a biologist at University of California, Los Angeles (UCLA), to the New York -based International Science Times . This is quite different from many other animals , which depend heavily on smells. Since faces play such a crucial part in the social lives of monkeys , could this explain why certain monkey species have such colorful faces while others have simpler, plainer ones ? To test this theory , a group of researchers from UCLA studied 139 monkey species , mainly from Asia and Africa, and analyzed hundreds of headshot  photos of those monkeys from their databases. It was found that species that live in larger groups have faces with more complex color patterns than those that live in smaller groups. According to Live Science, researchers believe that this is nature's way of making it easier for monkeys to recognize each other since those living in larger groups have to distinguish between a greater number of faces. This is actually not that hard to understand . Just imagine if there were 10 people standing in front of you, all wearing white clothes. It would be much more difficult to tell them apart than if they wore clothes with colorful patterns. However, if there were only two people that you had to identify, a lack of color wouldn't be much of a problem. Apart from the need to recognize group members , researchers found that geography and environment also affect monkeys' facial colors. Species that live closer to the equator in thick, humid  forests were found to have darker faces than those who live in dry areas further away from the equator. This is because darker faces help... Question: What is article mainly about? - The social lives of monkeys. - How monkeys tell each other apart. - A comparison between the face patterns of monkeys and those of human beings. - The different factors that determine monkeys' face patterns.
