13、and the second uses the radiocarbon dating.ZH：I see.How does the layer method work?RL：Well，look at the digram in your book.Think of a wastepaper basket.When you came into work，you ate an orange and threw the orange skin into it.Thats layer number 1.Later somebody threw some yogurt pots into it.Thats
14、 layer number 2.ZH：Oh yes，and then I threw some paper into it.So thats layer number 3.RL：Yes，and finally someone threw away some used envelopes.So how many layers are there in this wastepaper basket?ZH：There are four.RL：Which layer is the first and therefore the oldest?ZH：The orange skin.RL：And whic
15、h is the last and therefore the most recent?ZH：Of coursethe used envelopes.I see how it works now.But how does it help?RL：Well，layers of soil are produced at different times like the layers in your wastepaper basket.Each time people live somewhere，they make a layer in the soil.If they live there for
16、 a long time，they make a lot of layers.Each layer has a different colour and texture which we use to find out how old it is.ZH：How splendid!Part 2ZH：Now what about radiocarbon dating?RL：This is more scientific.It uses radioactivity to measure the amount of carbon in living things.The carbon in a dea

53、king sure that it was safe.The steps look as if smaller and smaller boxes were placed one on top of the other to make the step design.I think the second to be built was Pyramid No C，which bends at the top.It has smooth sides which the architects could have learned from building the step pyramid.But
54、the design is clearly not finished as the curve at the top of the pyramid is not smooth.The Egyptian architects have not yet completely mastered the art of building pyramids with smooth and evenly sloping sides.It is the shape that we call“a pyramid shape”today，so it must be the final one in this series of buildings.From the pictures we can see that the three pyramids all come to a point at the top.It is reasonable to assume that the pharaoh/god was close to the other gods.The pharaohs spirit could escape from the top of the pyramid and fly up to the sky，where the gods were thought to live.
