12．
Scientists have built an exciting project 270miles into space．Sixteen countries from all around the world worked together to （66）plan and build a permanent（永久的） space station．The 16（67）nations included the United States，Canada and so on．In fact，the International Space Station （ISS） is the （68）largest international scientific project in human （69）history．Project on the ISS （70）began in 1998and was completed in 2002．
Six people from different countries （71）live on the Space Station．It has a permanent laboratory where the scientists conduct research that they cannot do on Earth．These （72）studies will be possible because the space station is almost （73）completely outside Earth's gravity．Some of this important research will help scientists understand more （74）about human learning and memory．The scientists will also be able to study Earth systems such as the oceans，weather，climate，and plant （75）growth．These systems affect the quality of life for all people today，as well as for our future generation．
