The difference of the three 'de' (的 得 地)

的 is used to make things possessive, we usually do this by adding 's on the end in english. For example: 王老师的狗- Mr Wang's dog, 我的朋友的汽车-my friend's car. It is also used after an adjective that is describing a noun (adj+的+noun), for example: 红色的飞机-red plane, 美丽的人-beautiful person. 得 is put after a verb when you want to attach an adjective with it (verb+得+adj), for example: 他唱得很好-He sang very well，她学得很努力-She studied very diligently. The easiest way to think of 地 is putting ...-ly in english, you use this when you put an adjective first followed by a verb (adj+地+verb), for example: 我快地跑步- I ran quickly.
