北师大版第20单元第三课教材有误：在PIONEERS OF SCIENCE第三段至后一句中，Einstein then showed in his "theory of relativity" that not even time ,mass or length are constant----they change according to our experience of them.很明显not的位置不对，not应该放在are的后面。
在第四段至后一句话中，。。。which proved that the universe was vastly larger than had previously been thought 。很明显than的后面少了一个that 。
在课文的至后一段中，。。。the world as we know it today would have been a completely different place .很显然，as是定语从句的引导词，指代the world,定语从句中多了一个it 。
