【正文】 s be friendly and kind to those in need C Your body is special – no two people in the world are alike. Although you are different from everyone else, you have exactly the same body parts as the people around you, doing different jobs that keep all of us alive. What is inside my head? Your head houses the most valuable part of your body – your brain. As you are reading, your eyes send pictures to your brain which makes meaning from what you see. Your brain helps you to remember and think, and makes sure your body is doing what it should. What is my skin(皮膚 ) for ? Your skin covers your body. In most parts of your body, the skin is just as thick as half a centimeter( cm) . If you have your skin cut, it will have a quick cure and stop viruses(病毒 ) from getting into your body. Your skin also helps you feel the heat and coldness of the environment around you. Hair grows from inside the skin. When you feel hot, extra heat es out through your skin. As a result, your body temperature drops. How do I move? Muscles(肌肉 ) are found in most parts of your body. They work with your bones to help you move – whenever you cry or smile, eat or speak, walk or dance, etc. Why do I breathe? Your body needs to take in oxygen(氧氣) from the air and give out the unwanted carbon dioxide(二氧化碳) in the body. When you breathe, air es through your nose and mouth into your lungs where oxygen flows to different parts of your body. What makes me sneeze(打噴嚏) ? When dust or a strong smell gets into your nose, you sneeze. This is the way your body cleans up the dust in your nose. Your lungs push out the air and try to clear your nose. What does my heart do? Your heart is a very special muscle. It is slightly bigger than your fist (拳頭 ) and grows bigger as you do. If you place your hand on your heart, you will feel your heart beating which forces blood to move around your body. 49. Which part is the most valuable part of your body? A. Myskin. B. Mybrain. C. My mouth. D. My nose. 50. If you have no skin covering your body, what would happen? A. Viruses can’t get into our body easily. B. Our body can be guarded by our hair. C. Extra heat can only stay inside our body. D. We can’t feel the changes in temperature. 51. What can you learn about your body? A. Sneezing is a way to clear our nose. B. Our heart is the same size from birth. C. We take in carbon dioxide to stay alive. D. Our muscles stop working when we nod. 52. Which is the best title for this passage? A. What Your Body Needs B. How Your Body Works C. Why Your Body Grows D. When Your Body Moves D Holidays are really important. Many of us will have childhood memories of summer holidays where we were taken away from home to experience new environments and learn in different ways. But holidays are expensive and, for those on low wages(工資 ) or living on benefits, they are often unobtainable. Even the cheapest holidays require travel and other costs that are difficult for many families to meet. For working parents, the long summer break can be a very difficult problem for childcare. Their leave is only five weeks each year, but there is a need to spread this across the year. Couples(夫妻) can find themselves taking leave in turn in order to care for children who are on holiday. For some people, this makes even an affordable family holiday difficult. The schools that I visit in Nottingham are full of experienced teachers who are working on giving our children a caring and inspiring learning environment. The number of children receiving free school meals is quite large in Nottingham and many schools have breakfast clubs to make sure that children get a healthy start to the day. Most schools have programs of group or single educational support. Schools also have an important role in safeguarding children39。每個選項只能用一次。(共 10 分,每小題 2 分) At the moment, it may be difficult to imagine, but many people believe that, by the year 2100, we will live on the pla Mars. Our own pla, Earth, is being more and more crowded and polluted. Luckily, we can start again and build a better world on Mars. Here is what life could be like. First of all, transport(交通 ) should be much better. At present, our spaceships are too slow to carry large numbers of people to Mars—it takes a few months. However, by 2100, spaceship can travel at half the speed of light. It might take us two or three days to get to Mars! Secondly, humans need food, water and air to live. Scientists should be able to develop plants that can be grown on Mars. These plants will produce the food and air that we need. However, can these plants produce water for us? There is no answer now. There is a problem for us to live on Mars. Mars suck(吸引 ) us much less than Earth does. This will be dangerous because we could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier. There will probably be no school on Mars. Every student will have a puter at home which is connected to the Inter. They can study, do their homework and take exams in online schools. Each student will also have their own online teacher called ―eteacher‖. Life on Mars will be better than that on Earth in many ways. People will have more space. Living in a large building with only 10 bedrooms is highly possible. Many people believe that robots will do most of our work, so we have more time for our hobbies. However, in some ways, life on Mars may not be better than that on Earth today. Food will not be the same—me
