四、阅读理解
A
Many people dream of travelling into outer space. However, spending too much time in space may cause health problems, according to NASA. That’s why astronauts shouldn’t spend more than six months on the International Space Station (ISS) at a time.
　　Muscle（肌肉）and bone loss
In a weightless environment, astronauts don’t need to use their muscles to support themselves, so their muscles start shrinking. To keep their muscles strong, astronauts need to exercise about 2 hours each day on the ISS.
Sleep disorder（紊乱）
In space, the sun rises every 90 minutes. It is hard for astronauts to get used to this light-dark cycle when they sleep. Also, they need to sleep in a sleeping bag that is fixed to a wall, and it is uncomfortable. Studies have found that most astronauts only sleep about six hours each night, even though they should have eight and a half hours.
Brain changes
Scientists have found that the position of the brain changes during the spaceflight. It can affect how the brain deal with how we see, stay balanced（平衡的）and move around. That’s why some astronauts can’t control their movements and balance after returning to the Earth. Scientists have also found that astronauts may get used to this change after going on more spaceflights. But they still need to do more research.
