Take four or five hours off,not necessarily consecutive,and simply write down every accomplishment in your life, on or off the job,that made you feel effective.这个句子去掉插入语可以化简为Take four or five hours off and simply write down every accomplishment in your life that made you feel effective.请问这个化简后的是主语从句吗？如果是为什么引导词that不放在句首？
