    Recently the unmanned aircraft which are called drones (无人驾驶飞机) have come into use for a number of business purposes.

    Basically, a drone is a flying robot. The aircraft (飞行器) may be remotely controlled or can fly a{#blank#}1{#/blank#} 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{#blank#}2{#/blank#}in price more people have begun to use them. Rescue workers and fanners 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 (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{#blank#}3{#/blank#}. buildings. Rescue workers use them to look for people. And now farmers are using them to m{#blank#}4{#/blank#} their crops.

    Romain Faroux is a French businessman who starts companies. His father was a farmer. He believed drones could help fanners. He helped create a company that developed a small drone that could be controlled by people on the g{#blank#}5{#/blank#}. 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 smartphones 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 this 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{#blank#}6{#/blank#} 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{#blank#}7{#/blank#} to three hectares (公顷) in about a minute.

program such as "The Voice of China".

Meiyu, born in 1991, is from Turkey(土耳其). She is the youngest child of her family. After high school, many people learned English or Japanese, but Meiyu decided to learn Chinese in university. She learned Chinese for four years in Ankara University in Turkey, and got her name Meiyu there.

Meiyu fell in love with Chinese after going to university. She became more interested after she knew more about Chinese history. In the beginning many people did not understand her decision. But they all said Meiyu had made a right choice when she graduated from university in 2013. Since then, more Chinese have been visiting Turkey. The trade between the two countries also requires Chinese-speaking people. ＂Speaking Chinese means more job opportunities.＂ said Meiyu.

Now Meiyu has been in Wuhan, China for about two years. Besides going on studying Chinese, she shows great interest in Chinese kung fu as well, so she spends her free time on kung fu training with her coaches. Not only can kung fu help improve her health, but she is also fascinated by the history and culture behind it. Meiyu said, ＂The more I know about China, the luckier I feel to have been here. But the truth is that fun and pain go together in the process of learning.＂

Meiyu will graduate in June this year. Her friends want her to stay in China, but her parents hope she can come back home. Meiyu thinks it is difficult to decide. ＂Even if I go back to Turkey, I will choose Chinese language education as my job,＂ said Meiyu.
