     Life today has brought new problems. One of the biggest is pollution. Noise pollution makes us talk more loudly and become angry more easily. Water pollution makes our rivers and lakes very dirty. Air pollution is the most serious kind of pollution. Both water pollution and air pollution are not only dangerous to our health, but also dangerous to animals and plants.

     Many countries are making new laws to fight pollution. Factories must now clean their water before they throw it away. They can not let out dirty smoke into the air, either. More and more cars are now using a new kind of fuel(燃料) which does not pollute the air.

     Laws are not enough. We must all help. We can use paper bags, not plastic ones. We can keep old cans and plant flowers in them. Everybody must help to fight pollution because we can keep our country clean.

    A life coach is somebody who helps you reach all kinds of personal and professional goals(目标). Each of us has the ability to be our own life coach. Here is some advice about how to be your own life coach:

    Pay attention to your relationships with others. Ask yourself the following questions: How do you deal with disagreements? When was the last time you showed your family members that you care for them? Your relationships with friends, family members and teachers show a lot about the kind of person you are.

    Face the fears about the future. Now, imagine that one of your good friends told you that he or she was not strong enough to go back to school. We often give better advice than we are willing to take ourselves. Remember that even the most successful people were probably told that what they wanted to do was impossible. ①但是他们坚持努力工作，永不放弃。

    Develop your talents. ②If you want to achieve your goals, you will have to spend more time developing the talents you already have. And you should also uncover (发现)any hidden talents that you haven't discovered yet. So you can take classes in subjects that you are interested in, even if you have no experience.

    Be thankful. Take some time to be thankful for the things you do have. Remember positive (积极的) things. Think of the best days you have had in the past month or year. Remember special parties, vacations and holidays. Thank for the wonderful people you have in your life.

    Jack London was born in San Francisco in 1876. Life was hard when Jack was growing up and he started working when he was 10. He did lots of different jobs. In his free time he went to the library and he spent many hours there, reading. In 1894 he went back to school, and published his first short story Typhoon, off the Coast of Japan. Then in 1896 he went to the University of California at Berkeley, but he had to leave because of money problems.

    In 1897 he left for the Klondike Gold Rush in Alaska. However, he became ill and came home and started working as a full-time writer. He wrote short stories and soon he was well-known. In 1903 he wrote his most famous story: The Call of the Wild.  His next novel was The Sea-Wolf (1904) which is perhaps his best literary novel.  With the earnings he bought a large farm in Califonua, where he died in 1916, aged only 40 years old.

    London was a prolific writer in his short life.  Between 1905 and 1916 he published 18 novels and six collections of stories, as well as a play, various works of non-fiction and a biography.  He is best-known for his descriptions of nature and the animal world.

    Drones（无人机）are like planes, but come in many shapes and sizes. They have no pilots and controlled from outside the drones. During these years, they have been used to attack（进攻）enemies or moved goods in dangerous areas.

    Now small drones are a part of people's lives. For example, people use drones to take photos or make videos. Besides, a drone delivery (投递) service has proved successful.

    Online store JD can use drones to deliver small packages（包裹）. It has built several drone stations so that it can load(装载) and deliver its packages.

    Drones have made our shopping experience different. We can order a new coat in early morning and it will be delivered before we finish breakfast.

    Bizzby Sky, a UK company, has created a delivery service for small goods. Open a smartphone app(应用软件), enter your address, set a time and pay enough money for the delivery service. Then in minutes, a drone will do tasks for you.

    However, any drone company needs government permission (允许) to fly its drones in many countries. We believe we will see more and more drones with goods fly in the sky very soon.

    The sun was falling behind the hills. Andrea was driving back home to Brockboune. Then she saw an old lady, standing by the toad, with a sign saying "Brockboune" in her hand.

    Andrea stopped the car. When the old lady got in, Andrea could see that she was not that little. She was in a long dress and had a hat pulled down low over her eyes. She put her big brown shopping bag down onto the floor.

    "Do you live in Brockboune?" asked Andrea. "No, dear," answered the old lady in a low voice, "I'm just going to visit a friend, but my car won't start, so I decided to hitchhike."

    Something in the way the lady spoke made Andrea uneasy, Andrea secretly studied the half-covered face, the shapeless body, the arms with their thick black hairs… Thick black hairs? Andrea's blood froze. This wasn't a woman. It was a man!

    Her heart was beating wildly and her mind raced. Then suddenly, an idea came up to her. She stopped the car in a sudden. "My God!" she shouted, "A child! Did you see the child? I think I hit her!" "I didn't see anything", the "old lady" said, "I don't think you hit anything." "I'm sure it was a child!" shouted Andrea. "Could you just get out and have a look?" The "old lady" slowly opened the car door, leaving her bag inside. As soon as "she" was out of the car, Andrea drove away as soon as possible.

    Several minutes later, Andrea thought about the "old lady's" bag and opened it carefully. There was only one thing in it—a shining knife.
