Chava spent the next few months in hospital.Although she could breathe on her own after treatment，she was left paralyzed from the neck down.When she was nine，she was thrilled that she got the chance to go to school.However，it turned out that she was in a single room with a group of kids who all had mobility impairment. Some of those kids were also intellectually disabled.They weren't even allowed to eat lunch in the cafeteria. Chava now has a communication consulting firm.She even wrote a memoir about her life，titled A Life Not with Standing.Chava became an advocate for disability rights and has dedicated her life to speaking out against discrimination of disabilities in the world.During the pandemic in 2020，Chava spent most of her time inside，starting a YouTube podcast (播客) focusing on one of her passions，music. There has been positive feedback from listeners who have been touched and inspired by the songs discussed on the podcast.“Chava played a fabulous song called Mother by Tom Paxton.I was listening to it while driving，” said Barbara Schumer，a follower of Chava's podcast.“The lyrics were about adoption and I started sobbing in the car，since I have two children I adopted at birth.I wrote to her after that，and I think she's a remarkable person.” Despite her disability，Chava said，“Having a disability is an important piece of who you are，and I'm not at all in favor of living my life as if the disability is not important.But it shouldn't be the thing that holds me back from becoming stronger.” 语篇解读　本文是一篇记叙文。文章讲述了Chava Willig Levy的故事，她三岁半时因患小儿麻痹症导致瘫痪，但后来通过努力成了一名残疾权益倡导者，并通过播客激励他人，展现了她积极面对生活的态度。 4．What can we learn about Chava from the first two paragraphs?
