Listen to Part 1 of the tape and fill the layers in the “wastepaper basket” diagram below. yogurt potsorange skinwastepaperused envelopesListen to Part 2 and complete the passage.It uses radioactivity to measure the amount of _______ in the living things. The ________ in a dead body _________ at a ____ rate. We know how long that takes, so we can measure the amount of ______ and ________ how old a bone is.carboncarbondisappearsfixedcarbonwork outLook at this archaeological drawing of a
section showing buildings at different times
and work out the order in which they were
built. Answer key for Exercise 3: The oldest building is B because it has no layers underneath it.
The second oldest building is C because it has one layer underneath it. That layer is the remains of the building in B.
The most recent building is building A. It has two layers underneath. They are the remains of buildings B and C.Part 1
ZH: How can you tell how old the bones
are when you find them?LISTENING TEXT(P42)DATING METHODSZhou Heping has come to ask the archaeologist, Richard Leakey, how he dates the bones he finds.RL: There are two main ways: the first uses layers in the ground and the second uses the radiocarbon dating.
ZH: I see. How does the layer method work?
RL: Well, look at the diagram in your book. Think of a wastepaper basket. When you came into work, you ate an orange and threw the orange skin into it. That’s layer number 1. later somebody threw some yogurt pots into it. That’s layer number 2.
ZH: Oh yes, and then I threw some paper into it. So that’s 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 layers.
RL: Which layer is the first and therefore the oldest?
ZH: The orange skin.
RL: And which is the last and therefore the most recent?
ZH: Of course—the 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 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 2
ZH: 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 dead body disappears at a fixed rate. We know how long that takes, so we can measure the amount of carbon and work out how old a bone is.ZH: That's very clever. Is it accurate too?
RL: There are some problems with very old bones, so you are always given two dates.
ZH: How does that work? RL: Well, the date for a bone may be between 9,900 years and 10,100 years old.
ZH: Perhaps we could visit the site together sometime?
RL: Of course. Whenever you like!
