escape本身也有名词的性质,表逃脱,摆脱的意思.
句末 are there,outside-or as likely part of -the tent ,这此在句中作什么成份
事实上,末句中把括号去掉之后,结构就很清楚了：
the mean's of escape from holiday hell are there,outside-or as likely part of -the tent .
主语the mean's of escape
谓语are there
outside作为补充成分,破折号后的or句表示除了outside之外,还有另一种可能：在外边,或者几乎成了帐篷的一部分.
