The ver y large earthquake, striking an area where it was totally unexpected, obliterated the city of Tangshan and killed over 240,000 people — making it the deadliest earthquake of the twentieth century.What was the biggest earthquake ever?The biggest earthquake known in historical times occurred on 22 May 1960 in Chile, with a magnitude Mw of 9.5. It occurred because of a rupture in the Earth's crust that extended horizontally about 1000 km along the coast of South America; in some places this quake caused vertical uplifts as large as six meters. The second biggest earthquake known, with a magnitude of 9.2, occurred in Alaska on 27 March 1964; it had a rupture length of 800 km, and caused as much as 11 meters of uplift. Theoretical calculations suggest that these earthquakes are just about as large as possible for planet Earth. Suppose a hypothetical earthquake ruptures the entire 100 km thickness of the rigid tectonic plates, and suppose this rupture extends along a fault with length 1000 km with an average slip of 10 meters. Calculations show that this hypothetical earthquake would have a magnitude of about 9.3. Larger earthquakes would hav e to rupture an even longer fault with an even greater average slip; apparently this just doesn't happen.What was the most deadly earthquake ever?The 27 July 1976 earthquake in Tangshan, China (MS = 7.9) caused the greatest number of deaths of any recent quake known; the most reliable estimates are that about 242,000 lives were lost. Tangshan had a pre-quake population of about a million people; the main industry is mining. One reason the death toll was so high is because most of the structures in Tangshan were multiple-story, unreinforced brick and concrete buildings.Estimates of loss of life from the worst earthquake disasters are very unreliable; understandably, when tens of thousands of people are dead and most buildings are in ruins, there are more important things to do than to count bodies. However, there have been about five quakes in the twentieth century where reports of lives lost exceeded 100,000. Most experts accept that the most deadly earthquake in historical times occurred in Shanxi Province, China in 1556; about 830,000 lives were lost.Step III Unit DiaryGet students to assess their learning over the unit. By completing Unit Diary students will learn what their difficulty is and what they should do to improve.Step IV HomeworkPost your view on how to English well on the Bulletin Board.附件I.本单元课文注释与疑难解析1.

Unit 22 Environmental Protection语法篇____________________________________________________________________________________________________________________________________________________________________1、掌握直接引语与间接引语，现在完成时的被动语态，非谓语动词的被动语态。
2、灵活运用直接引语与间接引语，现在完成时的被动语态，非谓语动词的被动语态。
直接引语与间接引语一、概念引述别人的话时，一般采用两种方式：一是引用别人的原话，把它放在引号内，称为直接引语；二是用自己的话加以转述，被转述的话不放在引号内，称为间接引语。
间接引语在大多数情况下是一个宾语从语。
直接引语变成间接引语时，要注意以下几点：人称变化、时态变化、宾语从句要用陈述语序。
例如：直接引语：He said，“I want to have a drink now.”间接引语：He said that he wanted to have a drink then.二、变身方法1.人称变化：口诀：一主二宾三不变。
即直接引语的第一人称取决于主句的主语,第二人称取决于主句的宾语,第三人称一般不变。
1）He said, “I get on well with people here.”→He said that he got on well with people there.2）Susan said, “We can finish the work tomorrow.”→Susan said that they could finish the work the next day.3）John said, “Mary went to Beijing three days ago.”→John said that Mary had gone to Beijing three days before.2.时态变化：口诀：主句现在从不变，主句过去从顺延。
