Sample of writing:

Brief introduction to the Zhoukoudian Caves

Zhoukoudian is a small village situated about 50 km southwest of Beijing In 1928, Dr C. C. Young, a famous Chinese paleontologist, and Wenzhong Pei, a young Chinese geologist joined the excavation. Two lower jaws of Peking Man were unearthed in this year. To make the excavation more successful, Dr Weng and Dr

Black established "Cenozoic Research Laboratory" in 1929.The Peking Man Site also provides the more precise scientific data for the study of the evolution, behaviour,On the western side of Zhoukoudian Village, there are two parallel hills. The one on the east is lower and called Dragon-bone Hill. Tithe archaeologists have found human and animal bones in those caves. So they think it is reasonable to assume they lived in these caves regardless of the cold. They also discovered fireplaces in the center of the caves where Peking man constructed fires. That would have kept them warm, cooked the food and scared wild animals away as well; Peking man might have hung animal skins at rhea cave mouth to keep out the cold. Peking Man used needle to repair or sew things. The needle is made of bone. Peking Man used special ways to make the hole for the thread. They also made their own clothes entirely of animal skins. They might have used sharpened stone tools to cup up the animals and remove fat or skins. Then smaller scraper might have been used to clean the fat and meat from them. Peking Man also cared about their appearance. They wore necklace made of seashells. Some of the necklace beads are made of animal bones but some are made of shells, which shows us that all the fields around here used to be part of a large shallow lake. Perhaps there was trade between early people or they traveled to the seaside on their journeys.

Step II Leading in Ask the students to pit out the sentences that contain the same structure as “We have been excavating here for many years…”

S1: 1. We have been finding the bones of tigers and bears in the caves and we think these were their most dangerous enemies.

2. We have been excavating layers of ash almost six meters thick, which suggests that they might have kept the fire burning all winter. 3. Yes, indeed, as the botanical analyses have been specifically showing us, all the fields around here used to be part of a large shallow lake. T: What is the same structure in these sentences? Ss: “have/ has been doing sth.”

T: Yes, in this unit, we will learn “have/has been doing sty.” That is the present perfect continuous tense.

Step III Explanation To make students fully understand the grammar, explain and sum up in Chinese. 现在完成进行时: 现在完成进行时表示的动作从现在某一时刻以前开始,这个动作有可能停止,也有可能继续延续下去.常用时间状语有:by the end of, by this time, by the time, by等,如: 1.

I have been waiting for you roar two hours. (不延续) 2.

It has been raining. (延续) 3.

What have you been doing all the morning? I have been watering the flowers in the garden. 4.

I have been reading Lu Sun this week. 注意:

现在完成时的动作发生在过去,对现在有影响, 现在完成进行时强调延续或直接结果.如: You look so tired, what have you been doing? (直接结果) We have been discussing the problem but we haven’t drawn conclusion yet.

S2: How long have you been learning to fly an airplane, Sam?

2. S1: He swam till he felt very tired.

He has just stepped
