PLEASE DO NOT PROP THIS DOOR OPEN.
THIS IS A RESTRICTED AREA, WE DO NOT WANT EVERYONE TO HAVE ACCESS TO YOUR FOOD.
THANKS FOR YOUR COOPERATION!
这是贴在BREAKROOM门上的海报，提醒大家不要把门撑开，因为休息间的门有密码，有些人嫌进进出出总要输入密码麻烦，就用垃圾桶卡在门上，实际上，这是个限制区域（Restricted Area），只对本中心的工作人员开放，于是，便有了这张提醒海报。
prop this door open，意思是用物体卡在门口使门不能关上，to use an object to keep the door open，中间的宾语可以是Door，Lid，或者Cover，挡住门的物体也可以是人。
It means to put something in the path of the door or under the lid or cover so that it doesn’t close. A person can be what props the door open.
have access to，意即“有权访问”，you are able to see it or use it，比如，have access to the internet。
