Read the passage, and decide whether the statements that follow are True or False.

Everybody knows that in studying foreign languages practice is the key to fluency. All foreign language learners even the advanced learners need practice. There is a fact that a learner can know a lot of grammar rules and have a large vocabulary; however, they can't speak well yet. So the learners must know how to use what they have learnt, apart from the ability to explain grammar rules. Listening, speaking, reading and writing are all important skills but most English learners find listening and writing the most difficult.
