　　Ⅴ.任务型阅读
　　Every year there are hundreds of earthquakes in different parts of the world.In Sept.1923，Tokyo and Yokohama were both destroyed by an earthquake and the fires that followed it.They had to be completely rebuilt.One of the most serious earthquakes was in China’s Shaanxi Province in 1556.It killed almost one million people.
　　We measure an earthquake’s strength on the Richter scale.The Richter scale was introduced in 1935 in Southern California in the USA.It measures earthquakes on a scale of one to ten.Any earthquaring five or more is usually serious.
　　The earth’s crust(地壳) is made up of layers of rock called plates.As these plates move，they sometimes crash against each other，causing the crust to quake.In cities such as Tokyo，where small quakes happen quite often，many modern buildings are designed to be flexible so when the earth moves，they move with it.Unit 3　Science and nature
