课时学案Unit5 Meeting your ancestors记录天地【Introduction】Archaeology is the study of ancient civilizations by scientific analysis of physical remains found in the ground. But unlike history it often has to deal with civilizations that have no written records. So it is the job of archaeologists to try to find out as much as they can about the life and times of long dead people by looking at the places where they lived; what they wore, what tools they used and how they buried their dead. In this unit we will look at the life of early people by examining the evidence from the Zhoukoudian Caves and life in Ancient Egypt. We will also see how archaeology is helping to restore the Terracotta Warriors of Xi’an.Period 1 Warming up and reading【Project】In this lesson we’ll look at the life of early people by examining the evidence from the Zhoukoudian Caves.【Process】(2 ms)We are going to read the passage, whose title is ___________.The passage is about general knowledge of archaeology as well as history.1.

第10讲Meeting your ancestors 语法篇____________________________________________________________________________________________________________________________________________________________________1.掌握现在完成进行时的用法；2.能够区分现在完成时与现在完成进行时。
现在完成进行时（1）结构由“have/has been+动词的现在分词”构成，表示从过去某时开始，一直持续到现在的动作，可能刚刚停止，也可能还在继续进行。
例如：We have been looking for you for an hour.我们找了你一个小时。
（动作刚停止）She has been teaching English since she graduated.她毕业后一直在教英语。
(动作还在继续进行)We have been going over maths these days.我们这些天一直在复习数学。
（动作还在继续进行）（2）有时现在完成进行时不是指某动作一直在不停的进行，而是表示一直到说话时为止的一段时间内一再重复的动作，常常带有感情色彩。
例如：She has been saying that 20 times. 这话她已经说了20遍了。
He has been calling on her several times this week. 他这个星期几次来看他。
We have been having a lot of rain recently. 最近雨水很多。
（3）有时现在完成进行时表示刚才或近来发生的动作，也可表示知道说话时为止的一段时间内发生的动作，这一动做到说话时已经结束，而且一般不再继续下去；这种用法主要表示某一动作所产生的结果或对现在的影响。
