Integrated Writing　　Reading：Physicist Fred Hoyle casts doubt on the validness of the fossil of archaeopteryx, an ancient bird vital to the evolution from reptile to modern birds. He thinks that the fossil is faked by putting features of a modern bird into a layer of a limestone. The reasons he gives are　　1)The fossil is discovered soon after the publication ofDarwin’s theory of evolution;　　2) The fossil is too perfectly preserved to be true;　　3)When the limestone in which the fossil is stored in is cut in half, the two halves do not fit perfectly.　　Listening: The professor completely refutes Hoyle’s theory. The reasons are:　　1)The museum rejected the theory of evolution at first. This means the fossil could not be faked since even the museum did not approve it.　　2) The limestone in which the fossil is stored in is very smooth, so it is reasonable that the details are well preserved　　3) Scientists intentional removed some parts of the limestone, making it easier expose the bird’s tail.
