[Q]: Something strange was unbelievable. Take Robert for example. After the terrible car accident, his whole world had been completely dark and quiet for almost ten years. The loss of sight and hearing made him try many times to put end to his life. His family especially his wife did their best to tend and comfort him. By and by he finally regained the courage to live on. On a hot summer afternoon he was taking a walk with a stick near his house when a thunderstorm started suddenly. He stood under a large tree in order not to get himself wet. Unfortunately he was struck down to the ground by a lightning. The witnesses thought him dead but he woke up some 20 minutes later lying face down in muddy water below the tree. He felt that he was trembling badly, but when he opened his eyes ,he didn't dare to believe that he saw a plough( )lying near the wall. When Mrs Edwards came running up to him, she shouted their neighbours for help. And he saw her and heard her voice for the first time in nearly ten years. The news of Robert's regaining his sight and hearing quickly spread in his area. And many doctors came to prove the truth of the news. Most of them said that he gained sight and hearing again obviously from the knock of lightning; none of them could give convincing reasons, however. The only reasonable explanation given by one doctor was that, since Edwards lost his sight and hearing as a result of sudden shock in a terrible accident, perhaps the only way for them to regain was by another sudden shock.
[A]: What did Edwards see first after being struck down by a lightning?


[Q]: Young people frequently say that they want to exercise, but they just can't find the time. The solution just might be in-office interval training. Recent studies show that very short but intense exercise rapidly builds and maintains fitness and health, even when the workout is only a few minutes long. Work the stairs You can complete an excellent, effective -- and very brief -- workout in an office stairwell, says Martin Gibala, a professor of kinesiology at McMaster University in Canada and an expert on interval training. For a study that he and his colleagues presented earlier this year, they asked 12 out-of-shape women in their 20s to warm up for two minutes by slowly walking up and down stairs in a campus office building. They completed three of these abbreviated stair workouts per week for six weeks. By the end, their aerobic fitness had improved substantially, the researchers reported, by about as much as if they had been running or cycling each week for hours. Fidget your way to fitness. Parents and teachers may once have urged you to sit still, but wiggling, tapping your toes, standing briefly, and otherwise fidgeting as much as possible at your desk is in fact good for your body. In one recent study, college students showed healthier blood flow in their lower legs if they fidgeted than if they did not. Even better, a 2008 study found that among office workers, those who frequently fidgeted burned as many as 300 calories more each day than those who resolutely stayed still.
[A]: How many studies are shown in the passage?


[Q]: The first year after birth is called infancy. Infancy is a period when the baby grows very fast. During infancy, the baby doubles in length and triples in weight. Other important changes also happen during infancy: The babys teeth start to come in, usually at about six months of age ( Figure 1.1). The baby starts smiling, paying attention to other people, and grabbing toys. The baby begins making babbling sounds. By the end of the first year, the baby is starting to say a few words, such as mama and dada. The baby learns to sit, crawl, and stand. By the end of the first year, the baby may be starting to walk. Childhood begins after the babys first birthday and continues until the teen years. Between one and three years of age, a child is called a toddler. During the toddler stage, growth is still fast, but not as fast as it was during infancy. A toddler learns many new words. The child even starts putting together words in simple sentences. Motor skills also develop quickly during this stage. By age three, most children can run and climb steps. They can hold crayons and scribble with them. They can also feed themselves and use the toilet. From age three until the teens, growth is slower. The body also changes shape. The arms and legs get longer compared to the trunk. Children continue to develop new motor skills. For example, many young children learn how to ride a tricycle and then a bicycle. Most also learn how to play games and sports ( Figure 1.2). By age six, children start losing their baby teeth. Their permanent teeth begin coming in to replace them. They also start school and learn how to read and write. They develop friendships and become less dependent on their parents. There are numerous milestones that occur during the first few years of childhood. These include the use of language, walking and running, understanding simple concepts, pretend play, the development of fine motor skills, the development of independence, Children develop better motor skills as they get older. having temper tantrums, demonstrating separation anxiety, becoming fully potty-trained, showing natural curiosity.
