From my perspective, I won't entirely agree with the author. In my opinion, input can gain through writing and reflect back on reading. In addition, this should be analyzed by case by case. Take me as an example, I started to learn to write journal at the age of six and it wasn't until I finished writing 100 journals that my family allowed me to read English books. I felt like my reading skills are based on my writing abilities. I felt like compared with reading an authentic English novel, I'd prefer writing. And I can speak for language learners in China. Because when it comes to input for readings, we don't have time to soak into the knowledge for we are under huge academic pressure. I heard so many Chinese English learners complaining about how long the readings are and it always gave them a headache when they try to use input in learning. They would rather write than read the articles. Also, learning style and learning strategies should be taken into consideration as well. For me, I am a visual learner, and I think writing helps sort out the images in my head and makes it more clear. However, if it is an auditory learner, he/she might feel like input is gained through reading and it is vital to L2 writing development.
