Who's working while you re asleep?
Police officers
Some police officers answer calls every night at the station. Others go around the town and city on foot or in cars.因为他们辛勤工作，你才能安然入睡。
Firefighters (消防队员)
Even at night, firefighters are ready to help.Whenever they get a call, they will go at once to fight fires and help people.
Doctors
If you get sick or hurt at night, doctors can take care of you at the hospital. The doctor will examine(检查)you, give you medicine and even do an operation(手术)on you.
Bakers(糕饼师傅)
You may never think that bakers often start the day while you are still asleep. They prepare all the things they need for the day and then start working. Bakers want their bread and cakes to be fresh and delicious every day.
In fact, many other people work at night. Let's thank them for everything they do for us.
