First, your pronunciation stays in the imitation stage, and has not entered the stage of defining pronunciation rules, so your oral English foundation is not solid.

Second, you don't have a systematic vocabulary application, and the usage of a word in your mind is single, and your vocabulary is definitely not fluent enough (without systematic phoneme training, memorizing words is basically inefficient)

Thirdly, language is a process from imitation to use and then to communication. Television just tells you the experience you haven't told others. No matter how many words, phrases and sentences are dead symbols.

Finally, language needs systematic learning. Listening, reading, speaking and writing are not enough, but must be done comprehensively.
