1.we know _______doesn,t travel so fast as light.
答案：A,sound
2,all the ______are made of _______,not plastics.
答案：A,glasses ,glass
再问：语法根据
再答：理由如下：对于第一个题，你要注意前后的对应性，后面的“光’”是‘light'，这里为不可数名词，因此前面对应应该用“声音”（sound）；对于第二题，道理一样，后面为复数plastics（塑料），前面也应该对应用复数glasses（玻璃）。你能理解吗？
再问： so fast as light 的意思是？
再答： as（so）...as..是一个固定短语，表示：与..一样。 so fast as light 的意思是：跟光一样快。
