范畴三　人与自然 主题十　宇宙探索 Think about the following questions： 1．What do you think is the biggest problem for astronauts living in space? 2．Have you ever thought about travelling into space one day? Lead-in The first people to go into space only went for short trips to see what it was like. Today, astronauts can ①spend weeks or even months living and working in space. We all know that living in space ②is very different from living on the earth. So, what's astronauts' daily life like? 中考考点讲练 Brushing teeth Astronauts brush their teeth in the normal way as we do, but there is a difference!

However, not all food can be taken to space. For example, American astronaut John Young took a sandwich into space in 1965. If its tiny pieces get into space plane's electronics, it may cause serious malfunction． So, astronauts' food is specially prepared. The food trays(盘子) are prepared on the ground for each astronaut and sent to the ISS before he/she arrives. Red food trays contain food from Russia and blue ones contain food from American/ European countries. Exercise The absence of weight ⑤leads to health problems such as bone and muscle loss. So, on the ISS there is a running machine and a special exercise bicycle. Astronauts have to do at least 2 hours of exercise every day to keep in good shape.
