Elements are all around us. Iron is one of the commonest elements found within the Earth. You probably know the element oxygen. It is the element that we b (2) in all the time. And elements can combine (结合) to make new things l (3) H2O. This is hydrogen and oxygen put together...
根据第一段中remember that the periodic table is used to organize all the elements, or things that make up(组成)our world.可知是组成我们的世界的东西,故选B。 根据第二段开头Elements are all around us.可知元素遍布我们周围,后面列举了一些常见的元素,故选A。 根据文中Last December, scientists from...

The periodic table is ubiquitous within the academic discipline of chemistry and provides an extremely useful framework to classify, systematize, and compare all known elements of their chemical behaviour. For each element, the electronic configuration, atomic mass, and weight are displayed in a popup...
