Many of life's failures are people who did not realize how close they were to success when they gave up.how close是不是倒装句与强调句,语序是不是they were close to success
how close they were to success是感叹句 people who did not realize( how close they were to success)这里how 引导宾语从句,同时这句话是个感叹句 比如she is beautiful改写成how的感叹句就是How beautiful she is!
