Have you ever felt uncomfortable? Many of1feel uneasy when someone stands too close2us, talks to us too3or makes eye contact with us for too long. But have you ever wondered why those things make you uncomfortable?

    It's all about personal peace, which means not only4imaginary space around the body, but also the space around all the5. People feel that their space is being violated(侵犯) when they meet with an unwelcome sound, smell or look. This is probably why a man on a crowded bus shouting into his mobile phone or a woman next to you putting on strong perfume(香水) makes you feel6.

   7people have had a stronger wish to protect their personal space or not in recent times is hard to say. Yet studies of airlines show that people have a strong desire(渴望) to have space to8. In a survey by TripAdvisor, a travel website, people said that if they9pay more for some extra service, they would rather have larger seats than extra food.

    Although people may need their personal space, some hardly realize it. For example, people on a bus who hold newspapers10 their faces to read in fact keep a distance from strangers.

    Go and watch a library table. You will notice 11one of the corner seats will usually 12first, because they are the farthest way. What if someone sits13you? Maybe you will pile up books as if to make a wall.

    Preference ( 偏好) for personal spaceare different from cultur e to culture . Scientist s ha v e found that Americans generally prefer more personal space than people from 14cultures. In

    Latin(拉丁人的) cultures,15, people are more comfortable standing near each other.

    Chrissy had only been in heaven for a few days. She was a (n)1angel there. Even though she was the newest angel, Chrissy had been given a very important task (任务). She was in charge of the2. Every Monday and every Thursday, she had to be3that the clouds get together and spread their raindrops all over the world. Every living thing on the 4needed rain. Trees needed rain to grow5and strong. Grass needed rain to6green. All the animals had to have water to7and to take baths in. And of course flowers needed the rain to look lovely and smell wonderful. So making the rain come was a very important8! But no one had told Chrissy how to make it rain, and she didn't know what to do at all.

    Chrissy asked one of the old angels if he could9her. "The angel that had the job before you used to tell sad stories to the clouds, and that made them cry," said the old one. But Chrissy was a very10little angel and she didn't know any sad stories. So she didn't think that would work.

    Thomas Alva Edison is one of the greatest inventors of all times. One of his most famous achievements is the electric light. He tried thousands of times to make a long lasting light bulb (灯泡). Although the light bulb is not his invention, he is the only one to have made such a successful light bulb. Many people remember him for the invention of the electric light. He held a lot of patents (专利权) worldwide. Many of them were approved (批准) in USA.

    We can find his inventions in many fields. In fact, many of the advanced inventions were based on his ideas. He invented a phonograph (留声机), a film picture camera, a ticket recorder and so on.

    Edison was not a good student at school. But he loved to do new experiments. When he was still a child, he built his first lab to perform his experiments.

    An amazing story of Edison's childhood is that he almost made his servant die. Edison used to think that birds ate insects and these insects might make them fly. So, he collected these insects and blended them to make juice. He then let his servant drink the juice. After drinking the juice, the girl lost her sense. But luckily, she was saved.

    An Irish priest ( 牧 师 ) loved going fishing. It was his favourite hobby. However, the weather was so bad this year that he didn't have a chance to go fishing.

    It was very strange that the weather was good every Sunday. But Sunday was the day when he had to go to work. The coming Sunday was good again according to the weather report, so he called another priest and told him that he lost his voice and was in bed with the fever. He asked him to take over his work.

    The priest drove fifty miles to a river so that no one would find him. An angel in Heaven was keeping watch and saw what the priest was doing. He reported it to God. He thought God would do something about it.

    With the first throw of us line, a huge fish bit down the fish food. For over an hour the priest was busy running up and down the river bank to fight the fish. In the end, he landed the large size fish. It was a world record — a Salmon (鲑鱼).

    The angel did not know what was happening and asked God, "Why did you let him catch that huge fish? I thought you were going to teach him a lesson." God replied, "I did. Who do you think he's going to tell?"

    Some American Indians grew corn, sunflowers, beans, and pumpkins in their gardens. To prepare a garden, they first killed trees. Some Indians put a dead fish into the hole where they planted the corn in order to provide food for the corn plant.

    The Indians made little progress (进步) during the thousands of years before the Europeans came. One reason for this was that horses, cows, sheep, pigs, and chickens were not found in America. Without horses, the Indians had a hard time digging up the soil, and they could only get animal food by hunting. Another reason for their lack of progress was that they did not know how to use metals to make tools. Stones and flat bones do not make good tools.

    Indian hunters would sometimes hunt for days without finding anything. They learned to follow animal tracks (足迹).

    They learned to listen. In order to get close to their prey, the Indians had to move quietly. When they were close enough, they could shoot their arrows. Often, the prey got away.

    The Mayas were Indians. They were much more civilized ( 文 明 的 ) than American Indians. The Mayas were great builders. They knew how to write down their words, and some of their books still exist.

    Sammy looked out of the classroom window at a bird in a tree. He saw a worm ( 小 虫 ) in the bird's mouth. "Wow!" he whispered as he looked at the bird eating the worm.

    "Sammy!" his teacher Mr Maxwell said loudly.

    Sammy jumped and knocked his science book off his desk. Everyone in the class laughed and Sammy blushed. This was the third time today he had been caught not paying attention to the science lesson. It was just so easy to get distracted  (分心的) when people read aloud from the science textbook!

    It wasn't that Sammy didn't like science. He loved to learn about machines, Earth and animals. He even thought bugs and plants were great. He wanted to go outside and see how a snake lived. He wanted to watch plants growing from the ground as they did last month. He just didn't want to read about these things.

    Sammy thought Mr Maxwell would surely understand. "There was a bird with a worm in its mouth ..." Sammy began. Then he saw the furious look on his teacher's face. Sammy decided that he had better stop talking before Mr Maxwell became any angrier.

    A city without cars would be very strange, right? But Venice is such a city. Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands.       

    Even so, travel isn't difficult. The waterways have always been the best ways to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go.       They like to enjoy the scenery and cool summer nights while taking boat trips. They can talk to Other people as they go along.

    Venice grew out of small islands in saltwater lakes when some Italians escaped from a war more than 1,500 years ago, and built homes there.       

    Once, people used too much underground water. This made the city get lower little by little.      Another problem is the rising seawater. The temperature has risen over the years.      Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater.

    Scientists are trying different ways to stop the city from getting even lower.
