Question: Article: Let Children Roam Free Everyone agrees that playing outside keeps children thinner. The loss of opportunities for outdoor play is one of the main causes of childhood obesity. What is more remarkable is the growing evidence that children's mental health and emotional well-being are enhanced by contact with the outdoors, and that the restorative effect appears to be strongest in natural settings. Researchers are convinced of the depth of the connection between children's well-being and the environment, claiming that contact with nature may be as important to children as good nutrition and adequate sleep. But now children seem to get less touch with outdoor activities. The root causes of the dramatic loss of children's freedom lie in changes to the very fabric of their lives over the last 30 years or so. The growth in road traffic, alongside poor town planning and shifts in the make-up and daily rhythms of families and communities, have left children with fewer outdoor places to go. These changes coincided with the "culture of fear": a generalized anxiety about all imaginary kinds of threats, even though children are statistically safer from harm now than at any point in human history. These physical, economic and social changes and fears have been made use of by manufactures and advertisers, whose products and messages both reinforce the logic of keeping children virtual prisoners, and force us to compensate them in the only way our cash-rich, time-poor society seems to know: by spending money on them. Government must bear some of the blame for keeping children prisoners indoor, through their promotion of planning policies that favour cars over communities and profit over people. The real planning crimes lie in housing companies occupying attractive parks and green spaces, and in town plans that force families to depend largely on their cars. There is no doubt that traffic danger, unlike stranger danger, is a real threat to children and a constant worry for parents. Around 100 child pedestrians are killed every year, a figure that puts the UK near the bottom of Europe's child road safety league. It is no surprise that figures show a steady fall in children walking or cycling over the last twenty years, to the extent that while over 90% of children own a bicycle, just 2% cycle to school. Also, 30% of children aged eight to ten never play outside without an adult watching over them. In a single generation, the "home habitat" of a typical eight-year-old----the area in which children are able to travel on their own- has shrunk to one-ninth of its former size. Health experts have even created a new word, "obesogenic", to describe those aspects of our lives that make us fat, and top of the list is the design of streets, towns and cities.
Answer: exercising the mind

Answer: Playing outside is just as important as _ .

Question: Article: Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle. Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practical sewing machine. Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing Jane Eyre. To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious ,but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called "secret messages to ourselves ".
Answer: the only person at the time who knew the value of dreams

Answer: According to the passage,Elias Howe was _ .

Question: Article: I looked at my beautiful Christmas tree and sighed. It was time. The New Year was a week old and my tree still stood in the corner of our room with its collection of memories proudly displayed in a shower of colorful lights. I'd procrastinated(,)long enough. I got up, went to the garage and dragged all the boxes into the room. The garland was the first to come down. The tree looked naked already. I took the large ornament off next. They made a large pile on our bed. An hour later, our bed was covered with Christmas memories. Each pile contained an ornament along with its matching brothers and sisters from sets purchased many years ago. I prepared the boxes and carefully placed ornaments in their protective packaging, pausing every few minutes to admire a favorite. "Hey, little Santa!" I held the Santa from my childhood. "Thanks for being my friend for almost fifty years." He was a little ragged but still gives me a flood of wonderful memories. "Until next year, my dear friend." There was a collection of handmade ones. My children made in the their first years of school, more than twenty years ago. Made by tiny hands, they are far from perfect in design, but every year they go on my memory tree-memories of young giggles on Christmas morning and a smiling face when they handed them to me when I came home from work. "Look what we made, Daddy!" "Oh! It is beautiful. Let's find a special spot on the tree for it." Every year since, they are displayed. A few hours after I started, the filled boxes were back in the garage, the room was vacuumed and I sat staring at a barren corner. The room seemed so empty. It took me two days of work to assemble and decorate my tree, but only a few hours to take it apart. My tree is like a good marriage or a great friendship. Like the tree, they take a long time to assemble and decorate with memories, but can be torn down quickly. Every year I have to put my tree away, but not my marriage or friendships. I take great care of those. They get to glow in the corner of my life for as long as I live. I get to analyze my tree and find memories for a few weeks every year. I can do the same with the loves in my life every day. Take great care of your friendships and your marriage. Once they come down, they aren't as easy to put back together as a Christmas tree. Stand them in that special spot in the corner of your heart and admire their glow.
