（4分）现有液氧、氧化铜、二氧化硫、水银、高锰酸钾、汽水几种物质。其中：
属于混合物的是（填名称）（1） ；
属于单质的是（填化学式，下同）（2） ；
属于化合物的是（3） ；
属于氧化物的是（4）
汽水；O2、Hg；CuO SO2 KMnO4；CuO SO2
题目分析：混合物是由多种物质组成的物质，单质是由同种元素组成的纯净物，化合物是由不同种元素组成的纯净物，氧化物是由两种元素组成并且一种元素是氧元素的化合物．汽水中含有水、二氧化碳等物质，属于混合物．
液氧、水银等物质是由一种元素组成的纯净物，属于单质．故填：O2、Hg．
氧化铜、二氧化硫、高锰酸钾是由多种元素组成的化合物，故填：CuO、SO2、KMnO4
氧化铜、二氧化硫都是由氧元素和另一种元素组成的化合物，属于氧化物的是CuO、SO2．
点评：解答本题时要分析物质的元素组成和物质组成，然后再根据各类物质概念的含义进行分析、判断，从而得出正确的结论。
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.
