[简答题](翻译)To become a flexible reader, you need to know how to select and use a reading style that is consistent with your purpose for reading. Knowing when and how to use different styles will make you a flexible reader. Study reading is the reading style used by flexible readers when their purpose is to read difficult material at a high level of comprehension. When using the study reading style, you should read at a rate that is slower than your normal reading rate. Furthermore, as you read you must challenge yourself to understand the material. Study reading will often require you to read material more than once to achieve a high level of comprehension. Sometimes, reading the material aloud will also help you improve your comprehension.
