Mere exposure to English will not enable you to speak English. If you want to drive you have to get in the car and drive, if you want to dance you have to turn on the music and dance, if you want to swim you have to jump in the water and swim. In fact, swimming is the perfect comparison to learning English.
You can’t learn to swim by sitting in a room and reading books about swimming skills. In order to be a swimmer you’ve got to conquer you fear, you’ve got to survive and suck in water, yell for help, you’ve got to lose face many times before you can make it. But, to be a good swimmer you’ve got to practice again and again. To be a great swimmer you have to practice for years until you can harmonize every part of your body and mind.
Let’s do it! Let’s yell together! Speaking English is a piece of cake! Make your Chinese muscle international!
