任务型读写（共10小题；每小题1分，满分10分） 阅读下面短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词 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 Shanxi 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 earthquake measuring 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. Earthquakes can also break up gas or oil pipes. This can cause fires to break out, which can do as much damage as the earthquake itself. Another effect of earthquakes is tsunamis (海啸). These are huge waves created by earthquakes beneath the sea. They can be many metres high and cause great damage to coastal towns and cities. China, Japan, Russia and the USA have the highest occurrence (发生) of earthquakes in the world.
