As you read, notice what makes Laura a good role model. TR: 4 -A DETERMINED YOUNG WOMAN When Laura Dekkerwas 13, she had a dream. Her dream was to sail around the world on her own, Her passion for sailing started when she was young. She was born on a boat and spent the first five years of her life at sea. By the time she was seven, she was sailing in competitive races. Over the years, she learned everything about sailing and weather systems. When she was ten, she bought her own sailboat with money she saved. It seemed that there was no stopping her. However, it wasn't easy to followher dream. The main obstacle she faced was not hazardous weather but her age. People told her she was too young. They said that sailing on her own was beyond her ability and that the journey could have serious consequences, With determination, however, Laura convinced everyone that she was capable of sailing around the world alone. She believed that her mental and physical skills enabled her to endure such a long journey, Laura eventually set sail when she was 14. She sailed over 43,000 km (27,000 miles) and across 3 oceans. Her trip lasted 366 days. Life on the boatwas abitofastruggle, butshe pushed herself, She had no refrigerator or washing machine. There was no shower, and she had to repair everything herself, She spent weeks on her own but used her time well. She kept a diary and completed classwork to help her finish high school. Laura's determination helped her achieve her dream, After her trip, she spent time speaking about her experiences to adults and young people. She also wrote a book about her travels. She hasn't stopped sailing and says, “I still have a lot of dreams. You can never have enough of them.”© Reaa. circle the correct answers. 1, Laura wanted to sail because___ a.she boughtaboat .

As you read, think about how the title and the saying are connected. rR: 7 The New Digital Global Community ‘There's an old saying: “It takes a village to bring up a child.” This saying, or proverb, suggests that the community is just as important as the family when looking after a child. Both the family and the community share in the responsibility. Patrick Meier believes that new technologies do the same thing. He believes that digital technology is creating a global village where people care about and help each other in times of need. One type of digital technology that has made it easy to be involved in local or global events is crowdsourcing. Now anyone can take action. All around the globe, people are networking for the greater good, and not only in times of crisis. For example, digital volunteers have classified 4 million images of the surface of Mars. Without volunteers, this would have taken scientists many years to do. In Russia, a cell phone alert tells blood donors that someone in their local area, with the same blood type, needs a blood donation. In India, people are using “unsmart” phones as a tool to report government actions. In the United Kingdom, a site encourages older people who live alone to network and cook meals for each other. In the United States, a site for patients and families. means they can share experiences of looking after very sick family members. It also provides a rich resource for medical researchers. Nowadays, even animals benefit from digital technology! Across Africa and Asia, a website allows people to report on wildlife crimes. ‘The new digital global community is working together to research, explore, share, and survive disasters. It’s becoming a worldwide village with digital humanitarians ready to be responsible for making the world a better place to live in. 16© Read. Circle the best answer, 1.

A new company in California has developed a system of farming that uses Growbots. Growbots are greenhouses specially designed for city rooftops. What are the benefits of Growbots? Well, one benefit is that they fit into any type of space and are lighter than traditional greenhouses. ‘The greenhouses are also hydroponic, which means that the plants don't grow in soil but in nutrient-rich water. People who use Growbots look after the plants by using cloud technology, which can track and control conditions such as irrigation (or water levels), humidity, and plant nutrition. Many people who live in cities are already urban farmers. They grow vegetables in community or neighborhood gardens. This traditional type of farming takes time, though. It produces fewer vegetables and is very dependent on weather conditions. In addition, studies have shown that 2 urban farming is affected by soil conditions and air pollution. However, because the Growbot system contains its plants in the greenhouses and uses recycled water, the plants are more protected and the food is safer. It's unlikely that rooftop agriculture will replace conventional agriculture. Growbots aren't good for root crops, such as potatoes. However, they offer an excellent alternative for growing large amounts of lettuce and tomatoes. This would free up farmlands for other crops. Using Growbots would also cut down transportation costs and the negative impact on the environment. Now these vegetables would be grown and bought locally in urban areas, Vertical farming and Growbots are the results of creative thinking. These new methods try to manage our food resources for future generations, It could be some time before we see Growbots on rooftops in every city, But when we do, we'll know where our food is coming from! ‘ ° ° ° ° ° ° ° ° ° ° ° ° °eo Read. Check T for True or F for False. Rewrite any false sentences as true. 1. The Growbot farmer needs to check on the greenhouse every day. 2. Technology plays a part in caring for the Growbot plants. 3. Urban farming is not a new idea. 4, Growbot vegetables aren’t affected by air pollution. 5. One of the problems of using the Growbot system is getting soil to the rooftops. 6.

He believed that people should never stop exploring. He once said that it would be dangerous for the human mind to think that it knew everything about science and nature and that there ‘were no new worlds to conquer. Some people think we spend too much time and money on. exploration and that we know enough about the universe we live in. But ifwe didn'tkeep exploring, we wouldn't find cures for diseases or be able to manage our ocean resources. We wouldn't have knowledge about our past or the reasons for climate change. Without exploration, we wouldn’t have the technology we have today, and we wouldn't be looking into the significance of water and life on other planets and moons. Of course, any exploration involves risks. Even as children, curiosity and the excitement of something being a little dangerous encourages us to look over a neighbor's fence orwonder what would happen if we pressed a button ona machine. Scientists have been investigating the biological factors that make us explore. They've found that our curiosity and motivation to find and learn new things is driven by a chemical found in our brain. In some people, a high amount of this chemical ean increase their level of curiosity Fortunately, or unfortunately, not everybody has the same amount of this chemical, which explains why we all aren’t ready to zoom into space. Whether it's curiosity, chemicals, or special genes in our DNA passed down from our ancestors—the original risk takers—there are many reasons that encourage us to keep on exploring.© Read the article again.

We have created these alien worlds in our imaginations. Yet, if these worlds did really exist, itwould be very difficult to visit them. Fossils, however, allow us to travel back in time and give us a picture of a real “alien” world on our own planet. Itreally was an extraordinary place. In ancient times, fossils were used for decorative or religious purposes only. However, some believed that these fossils were a sign that mythical creatures, such as dragons, existed. Paleontology today, with the advantages of modern technology, gives us a more accurate picture of the planet before humans appeared. Animals, plants, fungi, and bacteria have all left behind significant evidence about what life was like in prehistoric times. Paleontologists can now study the tiniest details of the smallest fossils, X-ray machines, CT scanners, and advanced computer programs can analyze fossil data, reconstruct skeletons, and create the bodies and movements of | exinctorganisms. | But fossils tell us much more. They tell us about eating habits, which animal preyed on others, ifthere was enough food, and how an animal might have died. They tellus about climate. Air bubbles inside ancient trees allow scientists to study the chemistry of the oxygen inside. This can tell them if, for example, there were volcanic eruptions of other changes in the atmosphere at the time. In paleontology, no piece of information is useless. Each piece forms a picture of our planet before we even knew it existed. Every new discovery not only creates new mysteries, but also adds a deeper understanding of how life developed.© Read “Clues from the Past” again. For each answer, write the question based on the text. a They allow us to travel back in time. 2. No, some people thought fossils were evidence of mythical creatures.
