山东省临沭县2017届初中生第二届学科素养展示大赛英语试题（全国县级联考）
Think about the distance（距离） you traveled in the last six months of your life. About how many miles（kilometers） did you go? Lucid went quite a distance. On March 22, 1996, she started a journey. She traveled 188 days, 4 hours, and 14 seconds in total. This is a little over six months. So what distance did Lucid travel? She went 75.2 million miles（1,203,200,000 kilometers）!
How could Lucid go so far? How could she journey so fast? Lucid was an American astronaut and she was in space. She lived on a space station. The space station was the Russian space station Mir. She lived and worked with two Russian astronauts.
On Mir, it was hard for Lucid to know what day it was. Why? Mir. did not stay in one place. It orbited the Earth. It went around the Earth. Mir's orbit meant that darkness did not mean the day was over. Darkness fell many times during a 24-hour period. Darkness fell about every 45 minutes. Lucid did something to help her remember what day it was. She wore pink socks on every seventh day. The pink socks reminded Lucid about something else, too. The pink socks helped Lucid remember that Jell-O would be served for dinner. On Mir, Jell-O was a special treat. It was only served on Sunday.
Lucid worked hard to deserve the honor of working on Mir. She went to school for a long time. She was one of the first six women to be accepted into the astronaut-training program. She flew on several American missions. When accepted for Mir, she had to learn Russian in less than 18 months. On Mir, Lucid conducted many experiments. One experiment she conducted was with wheat. Lucid grew wheat. Growing plants in space was important, because green plants could provide oxygen and food for space travelers.
