Astronauts eat three meals a day: breakfast, lunch and dinner. Some food can be eaten in the natural form such as fruit. Other foods require adding water such as noodles. There are no fridges in space, so space food must be stored and prepared properly to avoid going bad.
Besides morning routine（常规）and eating in space, astronauts perform many tasks including checking the machines, updating computer equipment（更新电脑设备）, etc. At the same time, the control center on Earth sends messages to the astronauts through voice or email with new instructions to assist them in their daily routines.
What's more, living in space is not just all work and no play. A popular way of relaxation is looking out of the window. And they can also enjoy themselves by watching movies, reading books, playing cards and talking to their families during their free time.

2.(1)①放出　②吸收
思考1　(1)看到试管A中产生大量无色气泡，且U形管中a端液面下降，b端液面上升。
(2)铁粉与稀硫酸反应放热，致使瓶内气体膨胀，瓶内气压大于外界气压，从而将U形管中的红色墨水压往U形管的右侧。
(3)氧化钙或氢氧化钠[由于U形管的a、b两端液面的变化与(1)相同，则加入水中的物质应该是溶于水或与水反应放热的物质]。
