I immediately asked my parents for permission to take her to the lessons. What a76 chance tolearn dancing!One afternoon,I was practicing a new dance in my room,when Maggie walked in."What's the matter,Maggie?"I stopped dancing."Denis,you're a great dancer!Can you help me?""What is it?"I wondered."There will be a dancing performance in my school, but the boys think I'm slow, and 77 of them wants to be my partner.Could you dance with me for it?" Shelooked at me anxiously."You can be a good dancer!" I encouraged her, " Let's show those people thatthey have been wrong all along."In the following months, we practiced every evening, hiding from my parent I was having a fantastic time and soon Maggie improved a lot.Finally came the big day.I became 78 when I heard my parents would com e to watch the performance.As the music began,I took a deep breath and tried to calmdown.we moved 79 , shining with pride.From the cheering of the crowd, I wassure we were successful.My heart was beating wildly when I saw my father coming towards me.He puthis hand on my shoulder.

But there are 75 applesthat are especially important to the history of our humanbeings and they have changed the whole world.Long long ago when the world just started, apple wasa forbidden(被禁止的)fruit in the Garden of Eden,however, a girl named Eve stole and ate it. Unfortunately,she was discovered by God, and was driven away from the Garden together with a boy called Adam. After they left the garden, Adam and Eve had their own babies and became the ancestors(祖先) of all of us. This is the 76 of our world.In the Autumn of 1665, there was a young man sitting under an apple tree in his garden. His name was Newton. While he was thinking of one problem, suddenly, an apple dropped down from the tree and fell on his head. 77 this, Newton discovered gravitation(引力)on that day and his new idea of science made people really surprised and happy, also he changed our opinions about nature and the way we think, then people began to 78 what science was at that time.And today, Jobs Steve, this crazy old man changed the world by his apple products. For example, iPhones can be found 79 in the street. Young people feelcool when they use this kind of new high-tech(技术) product. Don’t you think that apple products have become a symbol of our time? As Jobs Steve often said he was born to change the world and he made it. 80 he has died, people remember him and miss him. It is because he made our life more colorful and amazing.75.

Basically, a drone is a flying robot. The aircraft (飞行器) may be remotely controlled or can fly a 81 through flight programs in their systems. The little planes used to be very costly. In the past, they were mostly used in the military (军事) . But as they have d 82 in price more people have begun to use them. Rescue workers and farmers are among the new users.A company in France is using drones to help farmersexamine their crops and limit the amount of fertilizer ( 肥料)they use. The fast development of computer technology,image sensing devices (图像感应设备) , satellite navigation(卫星导航) and cell phones has led to lower-priced drones. Researchers and developers have learned how to build smaller and less-costly drones .Moviemakers are using drones to film from the sky. Historians (历史学家.) use them when they explore a 83 buildings. Rescue workers use them to look for people: And now farmers are using them to m 84 their crops.Romain Faroux is a French businessman who starts companies. His father was a farmer. He believed drones could help farmers. He helped create a company that developed a small drone that could be controlled by people on the g 85 . They called it "Agridrone (农业无人机).'' It uses a special "optical sensor (光学感应器) "to examine crops.The technology used is similar to that used by smart phones except it has wings.A computer program directs the drone to fly over the crops. The sensor on the drone records four different-colored "bands" of sunlight ( 太阳光带) that are reflected off ( 反射) the crops.Jean-Baptiste Bruggeman is a farmer. He says the drone flies over his crops at different time of the season. He says ttfis provides a lot of information about his crops. The drone pictures show him the exact amount of fertilizer the crops need. It also shows exactly where the fertilizer is needed.Romain Faroux says farmers use information g 86 . by the Agridrone to place fertilizer only in areas where it was needed. This saves money and reduces pollution. Before they used the drones, farmers would put the same amount of fertilizer everywhere. Drones also save time because farmers can examine u 87 to three hectares (公顷) in about a minute.81.______ 82.______ 83.______ 84.______ 85.______ 86.______ 87.______V.Translation1.吉米没有意识到学习的重要性。
