Listening
Conversation 1
Student: Hi professor, I am your student from last semester.
Professor: Oh, of course. How are you?
Student: I am fine, today I am coming for some request.
Professor: What is it?
Student: My boy friend told me that now you will organize an opera event recently, can I come?
Professor: Oh some we cannot have you come free this time, you can go to buy the student tickets. Although it is not as cheap as ours, but if you do want to come you can give it a shot.
Student: Actually I already would like to attend this activity last semester, but I kind of miss it.
Professor: Really? How come?
Student: I had to go to work, you know, schedule conflicts.
Professor, Actually do you have the interest to be the volunteer there? I know they need people.
Student: Of course, but can I say your name to them? I don't know if they will have me there.
Professor: Yes of course, but I am not sure if it will work, because they don't know me. The only tip I can give you is that you can say you are major in music, they like students who have experience on this.
Student: Thank you professor!
Lecture 1
Professor: Not to be confused with the folk magic of the same name, hoodoos are the trademark rock spires. Millions of years of erosion and weathering have carved the colorful limestone rock of the Claron Formation into bizarre shapes and seemingly impossibly stacked structures. The totem-pole-like hoodoos are more abundant here than anywhere else in the world.
A hoodoo is a tall, spindly structure that forms within sedimentary rock and protrudes from the bottom of an arid drainage basin or badland. Hoodoos form over millions of years of erosion in areas where a thick layer of soft rock is covered by a thin layer of hard rock. Over time, hoodoos form as a small cap of the hard layer protects a cone of softer rock underneath from erosion.
Depending on the minerals found within the different. hoodoos often have lively color patterns. The hoodoos of Bryce Canyon are found in the park's horseshoe-shaped amphitheaters carved from the eastern edge of the Paunsaugunt Plateau.
The formation of hoodoo is long, but fortunately people can see it closely enough now.
Lecture 2
Professor: Prehistoric paintings of antelope, snakes and giraffes that have survived for around 5,000 years are now under threat from looting and a lack of protection.
The rock paintings, which include renderings of dogs and sheep as well as human figures, were discovered at Dhambalin, in a unique sandstone shelter close to the Red Sea in Somaliland, a breakaway state from war-torn Somalia.
They were found by Dr. Sada Mire in 2007, in what she says was first ever survey initiated and led by a Somali archaeologist in the region. Since then, Mire has discovered 100 cave and rock art sites across Somaliland, but they need desperately to be preserved.
Studen
t: Can we just put them in the museum so no on can touch it?
Professor: don't you think is better to keep them in the original place? We can paint several of them and put the rest for the tourist to touch and feel. This is also a good way to protect the rock.
Conversation 2
Professor: Hi Lisa, do you want to go to the math night? I think it is perfect to you.
Student: I had attended it when I was a child and I was very interested to it. That is why I am major in math now.
Professor: Great!
Student: I wonder if parents can attend this activity.
Professor: I think the answer is positive. The math is different now, some parents even say they cannot assist their children on math problem now.
Student: That is true.
Professor: The reason I want you to attend this program is because you will get credit with it, also improving your teaching skills.
Student: Good, what are my duties?
Professor: They will be teacher explain theories there. You can review and answer.
Student; That is wonderful, I will be there.
Professor: I am looking forward to seeing you on that night!
Lecture 3
Professor: Family traditions and rituals, typically passed down through generations, play an important role in family life. Traditions and rituals help to define family values, such as importance of family. For instance, a family who has the tradition of always gathering for dinner on the holidays demonstrates the value of togetherness. Through helping to shape a family's values, traditions and rituals work to give families identities which family members can feel a sense of belonging to. For the American family, many traditions and rituals can be linked to the history of America.
Lecture 4
Professor: New evidence suggests that precursors to modern polar bears first appeared about four or five million years ago, making the beginning of the evolutionary split much earlier than previously thought. The polar bear's ancestors diverged from brown bears and underwent a series of evolutionary changes in order to survive in the harsh conditions of the Arctic-adapting to a life of hunting seals and surviving extreme cold.
Interestingly, the genome evidence shows that after brown bears and polar bears separated, there were periods when they came into contact again. The new study also reveals surprisingly little genetic diversity in today's polar bears, suggesting bottleneck periods, probably during warm periods, when their numbers were severely reduced.
What does it mean in the face of the current arctic warming now taking place?
First, the longer evolutionary period shows that polar bears won't be able to adapt to changing sea ice conditions within a mere one hundred years.
Second, although the longer time frame means that polar bears survived previous warm periods, the temperatures reached in the Arctic if we continue on our present greenhouse-gas-warming course will be unlike anything polar bears have survived before.
