听力原文： In order to have a good understanding of foreign languages, four things are nece
ssary. First, you must understand the language when you hear it spoken. Second, you must be able to speak it correctly and fluently. Third, you must be able to read the language and fourth, you must be able to write sentences that are grammatically correct.
There is no easy way to be successful in language learning. A good memory will be of great help, but it alone is not enough to memorize grammar rules or words. "Learning through use" is a good piece of advice for those who are studying a new language. Practice is very important, for as you all know, practice makes perfect. You must practice speaking and writing the language whenever you can.
In addition to this, you should listen to songs or watch movies in the language. You should force yourself to listen carefully to these movies or songs so that your listening ability can improve quickly. To enlarge your vocabulary, the best way is to read novels. At the same time, it is important that you have confidence in your reading ability. From my own experience, reading such books makes me more interested in the language and makes me want to learn more about it.
