A sample version:
A 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. Zhoukoudian is a relic of primitive culture, 48 kilometers southwest of downtown Beijing, where Longgushan(dragon skeleton mountain) is standing. Several decades ago, local farmers mined limestone in Zhoukoudian, came upon some bone fossils and called them “the Dragon Bones”. Zhoukoudian became known as “Dragon Bone Mountain”. Drugstores purchased the bones as a medical ingredient. The news about the “magic bones” drew attention of scientists. In 1929 these limestone caves became world famous with the discovery of a skull and two teeth dating back 200,000 to 500,000 years. They were named Peking man.
The historical and cultural value of the Zhoukoudian site has been acknowledged by its listing as a World Heritage Site in December 1987 at the eleventh session of UNESCO.
Step Ⅱ Lead-in
Ask the students to point out the sentences that contain the structure as in “We have been excavating here for many years...”
Sample sentences:
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?
S: “have/ has been doing...”
T: Yes, in this unit, we will learn “have/has been doing sth.” That is the present perfect continuous tense.
