49、f our human beings and they have changed the whole world.Long long ago when the world just started, apple was a 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 c

50、alled 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

51、, 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

Read the passage and fill in the blanks with proper wordsRecently the unmanned aircraft which are called drones （無人駕駛飛機(jī)）have come into use for a number of business purp

55、oses. Basically, a drone is a flying robot. The aircraft (飛行器) 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 (軍事) . But as they have d 82 in price more people have begu

56、n to use them. Rescue workers and farmers are among the new users.A company in France is using drones to help farmers examine their crops and limit the amount of fertilizer ( 肥料 ) they use. The fast development of computer technology, image sensing devices (圖像感應(yīng)設(shè)備) , satellite navigation (衛(wèi)星導(dǎo)航) and

57、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.

59、業(yè)無人機(jī)).'' It uses a special "optical sensor (光學(xué)感應(yīng)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&quo

60、t; of sunlight ( 太陽光帶) 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
