5、arts left over from processing helped to give her the idea for a material that was useful and did no harm to the environment. “Why do we need to have hundreds of man-made polymers (聚合体)when nature has so many already available?” she asked. After months of testing, Hughes produced a strong, flexible

6、sheet that forms at temperatures below 100 degrees Celsius. Inventor James Dyson said that MarinaTex is stronger, safer and much more sustainable (可持续的)than plastic.

13、星人). Scientists need to have a lot of imagination to understand what an octopus is thinking!In the 1950s, the US Air Force sponsored scientists to study the way octopuses use their brains. They hoped that they could use this knowledge to help them build better computers. However, their brains were s

14、o complex that the scientists felt it of no significance to continue with it.

21、 the sea. C. It is useful to copy their language. D. It is difficult to understand them. 【解析】选D。细节理解题。最后一段作者谈到 “Theres a long way to go to get to know the octopus completely. (完全了解章鱼还有很长的路要走)”,可知作者认为要了解章鱼不容易。. 完形填空Exam anxiety is something that almost every person experiences during his or her stude
