Every job 2．  (require) different things. For example, working in a company often needs good 3．  (communicate) skills. If you are 4．  (friend) and communicate well, you may do well in jobs like sales or teaching. When you go to 5．  interview, the company may ask about your skills. Sometimes, your ability to work with others 6．  (test) in the interview. This shows 7．  communication and teamwork are important. In fact, training 8．  (need) in most jobs. New workers 9．  (give) training courses during their first weeks. These courses help them learn new skills. Whether you want to be a doctor or a designer, 10．  (train) helps you get ready. Remember, your personality and skills make you fit for a job. So study hard and practice skills —they will help you in the future! 提升篇 Li Hua and his friends are discussing their dream jobs. Wang Tao says he wants to be a pilot because he has 11．  (be) to many places with his family. Zhang Peng thinks being a reporter is 12．  (interesting) than other jobs. He says, “13．  (if) you are a reporter, you can meet different people every day.” Zhao Xin has just joined the discussion. She wants to be a nurse. She says, “My mother is a nurse. She has worked in the hospital 14．  (for) ten years. I think her job is the 15．  (meaningful) of all.” Li Hua nods. He says, “My cousin is a programmer. He 16．  (work) for a big company since last year. He says the job is hard but fun.” Wang Tao adds, “My father told me that a good job 17．  (be) not just about money. It’s about doing something you love.” Zhang Peng suggests, “Why not 18．  (visit) more workplaces? We can learn 19．  (much) by seeing real jobs.” They all agree. Li Hua says, “Let’s 20．  (make) a plan for the summer holiday. We can ask our parents to help.” The friends feel excited. They know that finding a career is a long journey, but it’s never too early to start. Unit 2 Growing pains and gains 基础篇 We all face different feelings while 21．  (grow) up. It’s normal to feel upset, angry or worried when we have problems 22．  friends or family. Bad feelings may influence our lives. Last month, I fought with my best friend Harry. I lent him my favorite guitar, but he returned it with an ugly mark. I was 23．  (fill) with anger and said hurtful things to him. He stopped talking to me. I felt lonely and worried. My teacher Ella advised me 24．  (call) him. At first, I was afraid to say sorry. But I knew our friendship was important. I called Harry and said, “I’m sorry, I shouldn’t have been hard on you.” He also felt bad and said he didn’t mean to break it. We 25．  (clear) the air at last. I told him the guitar was a birthday present from my dad, and it meant a lot to me. Harry promised to be more 26．  (care) in the future. Learning to solve bad emotions 27．  (be) important for growing up. 28．  we may argue, we should try to understand each other. We should care for 29．  (we). If we do so, we will grow up 30．  (healthy) and happily. 提升篇 Many teenagers feel upset easily when 31．  (grow) up, and there are many reasons for it. Some feel upset because of too much study pressure, some because of arguments with their parents, and others because they can’t get along well with their friends. No matter what 32．  (cause) the upsets, it’s important to find proper ways 33．  (deal) with them. My cousin, Linda, is 34．  14-year-old girl. She often feels upset because her parents are too strict 35．  her. They always ask her to get good grades and don’t allow her to do what she likes. Last month, Linda had a big 36．  (argue) with her parents because they didn’t let her join the school music club. She felt very sad and cried for a long time. Her teacher found her upset and talked to her. The teacher told her to communicate with her parents 37．  (patient) and tell them her true feelings. Linda followed the teacher’s advice. She talked with her parents and explained that music is her hobby by 38．  (her) and it can help her relax. Her parents finally understood her and 39．  (allow) her to join the club. Linda told me that talking to others is the best way to deal with upsets. She also said that we should never give up 40．  we feel upset. Instead, we should face our problems bravely and find ways to solve them. Unit 3 What makes a great team? 基础篇 Working on a team is quite important. However, if people on your team are not good at 41．  (communicate), you may often feel terrible. To create a successful team, good communication is 42．  most necessary part for both the leader and the team members. The following are some helpful suggestions. Listen to other people actively. When someone is speaking to you, you’re supposed to listen to him actively. 43．  you’re not certain about something, you should ask him about it. In this way, you can get your answers to some 44．  (question) before moving on. Think about other people’s ideas 45．  (careful). When someone tells you about his ideas, you should think about them carefully, no matter how silly they may seem. This shows you are 46．  (interest) in his ideas and 47．  (make) him feel good. Share your ideas with other people. When you have a new idea, talk 48．  it with your team members. This helps to get better ideas. Besides this, it also helps to improve your relationships between you and your team members. Don’t criticise other people. When someone on your team does 49．  (anything) wrong, don’t criticise him. You can help him to find out reasons and then help him to deal with the problem. Criticising your team members too often makes them 50．  (keep) away from you. As a result, you may feel lonely. 提升篇 Long ago, there was a small village near a mountain. People in the village often 51．  (argue) and fought over the things that they needed. And they thought working with others was awful. One day, wise Alex came to the village. He wanted to teach the villagers about the 52．  (important) of teamwork. He noticed 53．  heavy stone in the middle of the village square. Alex told the leader of the village, “The stone is 54．  (value). You can hold a meeting to tell the villagers about this. 55．  the person can carry the stone to the top of the mountain, he can get it.” At first, everyone was silent when they heard the news. But after a while, a strong villager stepped forward to have a try. His strong body was one of his 56．  (strength). However, he failed. Then some other villagers tried one 57．  one. They failed, too. Alex then advised them 58．  (move) it together. The villagers followed the 59．  (suggest). To the villagers’ surprise, they could 60．  (move) the heavy stone finally. Unit 4 Helping out 基础篇 Alex smiled and said, “Many hands make light work.” This task certainly played a key role in showing them the power of working together. Helping others is a beautiful tradition in our society. Last month, our class organized an activity to help the elderly in the community. We planned to clean their rooms, chat with them and bring them some gifts. Before the activity, our teacher told us that we 61．  (must) be patient with the elderly. They 62．  (may) have hearing or vision problems, so we 63．  (should) speak slowly and clearly. We 64．  (can) also bring some old photos to share with them, because they 65．  (may) enjoy talking about the past. On the day of the activity, I went to visit an old lady named Mrs Li. She lived alone and felt lonely. I helped her clean the windows and arrange her books. She told me many interesting stories about her youth. I found that she 66．  (must) be a very brave woman when she was young. She also said that my visit made her very happy. After the activity, I realized that helping others is not difficult. We 67．  (need not) do big things. Even small talk or a smile 68．  (can) bring warmth to others. I 69．  (will) definitely join more such activities in the future. I believe that if everyone 70．  (can) offer a little kindness, the world will become a better place. 提升篇 It was just before 2:30 pm in my hometown, Wenchuan. I was having a music lesson at school. Suddenly, the ground shook hard and I 71．  (throw) to the floor. People were shouting all around me. I jumped to my feet and rushed outside. I was shocked 72．  (find) all the other buildings were reduced to pieces. I was shaking all over with fear. Then, a pair of strong hands reached out to me—I was saved. I can never forget those soldiers, 73．  (fireman), doctors and nurses. Day and night, they raced against time to save as many people as possible. I was 74．  (deep) touched by their courage and hard work. So I made up my mind to become one of them. And I did! I 75．  (graduate) from college and became a nurse. One day, I heard another hospital needed support. Right away, I signed up to help. I still remembered the 76．  (warm) of those helping hands 12 years ago. It was time for me to offer 77．  (I). The work was by no 78．  (mean) easy. The head nurse, Ye Man, gave me a lot of help. For me, she was a patient teacher and a kind friend. However, this wasn’t the beginning of our 79．  (connect). She had offered a helping hand to Wenchuan 12 years ago. Can you imagine my surprise? At that time she was my age, and also a new nurse, just like me! Even today, I still feel 80．  (luck) to have had such an amazing experience in life. Love leads to love, and so creates a circle of goodwill and kindness. Unit 5 Looking into nature 基础篇 Long ago, people liked to find pretty stones. One kind of stone was called amber (琥珀). It looked like hard yellow honey. Sometimes a small bug was inside. One day, a man looked at a piece of amber. A tiny butterfly wing 81．  (survive) inside it for a very long time. The wing was soft. It had small lines on it. The stone gave us plenty 82．  facts about old times. 83．  the stone was small, it told a big story. Butterflies were here long ago! After seeing this, scientists became very excited, and they wanted 84．  (enter) the world of the past. Scientists said the amber should 85．  (remain) in a museum, so everyone could see it. The stones could not tell their stories by 86．  (them). People had to look at them with care. Of all the old stones, this one had the 87．  (old) story about the butterfly. It was like 88．  open door to the old world. The wing stayed in greatest 89．  (safe) inside the gold stone. So we can see it now. Thanks to it, we look at old bugs very 90．  (different) today. They were not dull. They were bright and busy, just like the ones in the park. 提升篇 Amber, a golden fossilized resin, 91．  (be) famous for keeping ancient life for millions of years. It serves as a window on the past, 92．  helps us know much about the ancient world. Recently, scientists 93．  (find) a special piece of amber from Asia, in 94．  there is the tail of a dinosaur with beautiful feathers. This 95．  (discover) completely changes people’s ideas about dinosaurs. Scientists used to believe that dinosaurs were just huge lizards, 96．  now we know that some of them had feathers. Besides, more than 300 new species 97．  (discover) with the help of amber so far. Professor Wang, a great botanist, spent over 70 years 98．  (explore) China’s plants. He fell seriously ill many times during field work, but he never gave up. His spirit tells us that 99．  (keep) exploring is the key to unlocking nature’s secrets. We should learn from him and try our best 100．  (protect) and understand nature. Unit 6 Living with nature 基础篇 Have you ever taken a bike ride in the sun? It might make your ride a little 101．  (hot), but a cycle path in a sunny area can be a good thing. In fact, in the Netherlands, one company decided to build a cycle path that can create energy using the sun. In the town of Krommenie, there’s a cycle path of seventy meters with solar 102．  (panel) in it. They get light from the sun. They then use that light 103．  (produce) electricity, which is used for street lights and so on. In its first year, enough energy can be provided for one house for a whole year! Developers are still doing research. They must make sure the path 104．  (be) strong enough for buses to drive over it. They must also make sure the path isn’t too smooth because that could make people fall over 105．  (easy). This test path must be just right before this type of path can 106．  (build) in other places. In another Dutch town, Eindhoven, there is a cycle path that 107．  (use) solar energy to make art. The path, which 108．  (open) in 2014, is made up of thousands of tiny lights that get the light during the day and give off light at night. From above, 109．  (this) lights look like the famous painting The Starry Night by Dutch 110．  (art) Vincent van Gogh. This one-kilometer path is to honor Vincent van Gogh, who lived in this area from 1883 to 1885. It’s a beautiful and creative way of using the power of the sun, and the path now receives many visitors. 提升篇 Our earth is our home. Many 111．  (villager) live in the countryside. They grow wheat and other crops. 112．  (according) to the survey, some areas are facing water 113．  (short). It is hard for animals and plants 114．  (survive) in the desert. We have rich 115．  (nature) resources, but we waste too much energy every day. We should be 116．  (energy) in protecting the environment. We need to use clean 117．  (resource) and stop pollution.
