I always think my daughter Kendall is the best—that's just what parents do. When she was only three, she1 for the people, like a little angel.

    When Kendall was five, we noticed that she 2 had a tic(面部抽搐). When the problem got worse, we took her from doctor to doctor. 3 the treatment, Kendall continued to sing. Surprisingly, her tics disappeared when she sang.

    When Kendall was sixteen, we thought she would be cured soon. However,a(n)  4 thing happened.

    At a party, Kendall jumped on a friend for a piggyback ride. He bent lower than she expected, and she jumped 5 than he expected. Kendall flew over his back and 6on the floor — on her neck. She was rushed to hospital, paralyzed(瘫痪）from the neck down. She couldn't7. But her biggest8 wasn't whether she would walk again, but was whether she could try out for a show called American Idol.

    As the days went on, feeling on her left side 9, but she was still paralyzed on the right. We weren't sure how much of her10 would come back. A friend brought a microphone and put it on her bed. Every day, Kendall tried hard to pick it up . It was more 11 for her to pick up that microphone than a spoon or fork.

    Sometimes she had to bite a toothbrush to take her mind off the pain. We all cried because of the 12 we witnessed. But on the day—only three months after her 13—we cried full of joy when she sang, 14 she didn't enter the Top 24 of American Idol.

    When she was a little girl, she asked me 15 it was she that had tics. My heart hurt, but I told her, "Kendall, you have a pure heart, a fantastic voice, a strong mind. And you are a beautiful presence. "

    "Save the whales!" That's what the picture on Jake Smith's bedroom wall said. Jake liked having a picture that said something important: that showed he cared. He just never expected to get a chance to save a real whale, one right in his own neighbourhood.

    It was a Saturday morning when the newspaper first reported the whales' coming. A group of the animals were swimming close to the beach in Jake's hometown. All the local people rushed out to the beach to see them. They were expecting a beautiful show, better than a movie, but nothing they'd have to do anything about.

    Then one whale swam in the direction, directly towards land. It came in with the waves, and when the waves receded. Its huge body on the sand. Suddenly, Jake and his family and all the others were no longer sightseers. They had to become rescuers. A few people ran towards the animal. They pushed and tried to force the whale back into the water, but it was no use.

    An animal rescue service team soon arrived in a truck with heavy lifting machinery, to help move the animal. Jack and his family couldn't do much on the beach, so they went back to their house and made sandwiches and hot tea for the rescuers. At least, Jake thought, they could help in some way.

    Back at the beach, they offered the food to the rescuers and were happy to see that it was needed. It was getting dark. Some people lined up their cars along the beach and shined the headlights on the sand. The rescuers would not give up. After trying many times they were finally able to lift the whale into the water. Everyone cheered when it headed out to sea. It swam out about a mile and then disappeared for a moment under the sea. Then, in what looked like a jump of joy, it rose high above the water—a thank-you to those who had worked so hard to save his life.

    Sometimes it seems that time is flying. Perhaps it doesn't need to feel this way. Our experience of time can be possibly changed. By understanding the psychological(心理学的) processes behind our different experiences of time, we might be able to slow down time a little.

    One basic law of psychological time is that time seems to slow down when we're exposed(接触) to new environments and experiences. The law is caused by the relationship between our experience of time and the amount of information our minds process. The more information our minds take in, the slower time seems to pass.

    It follows, then, that we have different experiences of time in different situations. In some situations, our life is full of new experiences. Our minds process a lot of information and time seems to slow down. In other situations, we have fewer new experiences and the world around us becomes more and more familiar(熟悉的). We become insensitive to our experience, which means we process less information, and time seems to speed up.

    How can we slow down time? Here are two suggestions.

    Firstly, since we know that familiarity makes time pass faster, we can expose ourselves to as many new experiences as possible. We can give ourselves new challenges, meet new people, and expose our minds to new information, hobbies and skills. This will increase the amount of information our minds process and expand(增加) our experience of time.

    Secondly, and perhaps most effectively, we can give our whole attention to an experience-to what we are seeing, feeling, tasting, smelling or hearing. This means living through our senses rather than through our thoughts. For example, on the way home, focus your attention outside of yourself, instead of thinking about the problems you have to deal with. Look at the sky, or at the buildings you pass, traveling among them. This open attitude to your experiences helps take in more information and also has a time-expanding effect.

    To a certain degree, we can understand and control our experience of time passing. It's possible for us to slow down time by expanding our experience of time.

    In our daily life, robots are often found to do work that is too dangerous,  boring, difficult,  or dirty. And we often see kids play with toy robots.

    But what exactly is a robot? There are some important characteristics(特征 ) that a robot must have. These characteristics might help you to decide what is and what is not a robot. It will also help you to decide what you will need to build into a machine before it can be considered as a robot. A robot has these important characteristics.

    Sensing First of all, your robot would have to be able to sense the environment around it. Give your robot sensors (传感器)：light sensors( eyes ), touch sensors (hands), chemical sensors(nose), hearing sensors(ears) and taste sensors (tongue).

    Movement A robot needs to be able to move around its environment. It can move on wheels, walk on legs or be driven by small engines(发动机). A robot can move either the whole body or just parts of it.

    Energy A robot needs to be able to power itself. Some robots might power itself with sunlight,some might with electricity, while others with the battery(电池). The way your robot gets its energy will depend on what your robot needs to do.

    Intelligence A robot needs some kind of "smarts". A programmer is the person who gives the robot its "smarts". The robot will have to have a certain way to receive the program so that it knows what it is to do.

    Getting electricity has always been a problem for the 173 people living in Nuevo Saposoa, a small village in Peru, South America. However, things went from bad to worse in March 2015 after heavy rains damaged the only power cables in the area. The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.

    Luckily, researchers at the University of Technology (UT) in Lima, Peru heard about their problem and found a wonderful solution. They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies. The lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.

    While that may sound amazing and even impossible, the science behind the ides is quite simple. As plants create their food (using the sun's energy, water and chemicals from the soil), they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons – the building blocks of electrical energy. The UT team put special sticks inside the soil to capture the energy and keep it in the lamp's batteries for later use. The researchers say a single charge can power a 50-watt Led light for two hours - enough time for local villagers to get their evening work done.

    The university gave ten Plant Lamps to the villagers of Nuevo Saposoa in October 2015. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities, 42% of whom have no electricity.

    In 1997, Lottie Williams was walking through a park in Oklahoma, USA. with her friends.         She picked the object up. It was about as heavy as a tennis ball. Later, scientists told her it was a piece of a Delta II rocket that had been used to launch a satellite(发射卫星).

           We need satellites to send and receive TV and radio signals to report the weather and for many other things. But when they become old or break down, we just leave them there. They become space junk.

    Scientists think there are about 16,000 objects larger than 10 centimeters wide flying around the Earth ,and tens of millions of smaller objects too.         That's fast! And it's their speed that makes these pieces of space junk really dangerous. If one small piece of space junk hits something at high speed, it can do a lot of harm.        But in 2009. an old Russian satellite hit an American satellite and created 2, 000 pieces of space junk.

    Pieces of space junk enter the Earth's atmosphere(大气层) again. Lottie Williams is perhaps the only person who has been hit. Most space junk burns up and doesn't reach the Earths surface.        It made a hole in the ground 30 centimeters deep and over 3. 3 meters wide. Lottie was lucky she wasn't hit by it!

    In a tree in a forest, there lived many birds. They were happy in their small nests(鸟巢 ). Before the arrival of the rainy season, all the animals        ( 修缮) their homes. The birds also brought twigs ( 细枝)and leaves to make their homes        (安全) than before. "We should also store some food for our children. Said one of the birds. So they collected food and kept       （他们自己）busy preparing for the hard times.

    Soon the rain came. It was so hard that all the animals and birds stayed in their homes. It        ( 持续)raining for many days. One day, a monkey that got wet in the rain came into the forest. He tried his best to get a shelter（庇护处）, but he        (失败). The leaves were not thick        (足够)to save him from the rain.

    The birds were watching all this. They felt sorry for the monkey but there was little that they could do for him. One of them said. "Brother! Our small nests are not big enough to give you a shelter. "Another bird said," All of us        (准备)for the rainy season. If you had, you would not be in this       （状况）．"

    "How can you tell me what to do? " the monkey shouted at the second bird        (生气地). He took hold of the bird's nest and threw it on the ground.

    The poor bird thought，"Fools（愚人）       （从不）follow good advice. It's better not to advise them. "

    Lao Tzu was a philosopher (哲学家） in ancient China. He        (work) as an archivist（档案保管员）in imperial library, which gave him the chance to read more and learn a great deal of knowledge. As a result he got a large        (number )of students and fans. And it is said that even the famous Chinese philosopher,Confucius, heard about Lao Tzu, and came to        (visit) him.

    Lao Tzu believed that the human life, like everything else in the world, is influenced by outside forces. He believed "simplicity"to be the key to        (true), encouraging people to watch and think        (careful)to understand the laws of nature.He also advised people to build up        (person )power, and use it for leading a good life with love.

    Here are several        ( amaze) /quotes (语录）of Lao Tzu. I believe you will learn a lot from them.

    When you accept        (you), the whole world accepts you.

    He who talks more is sooner tired.

    A journey of a thousand miles begin        one step.

    If your actions inspire others to dream more, learn more, do more and become more, you are a leader.

    Knowledge is a treasure,        practice is the key to it.

    To become learned, each day add something.
