　　.閱讀理解

　　(2010·鄂州市高三摸底考試)

　　“Around 500,000 years ago, at the Peking Man Site at Zhoukoudian in Beijing's suburban Fangshan district, which is about 50 km from the city of Beijing, there lived early human beings，” says a China history textbook.

　　The textbook now has to be revised. New dating techniques suggest the remains of Peking Man—found in the 1920s—are over 200,000 years older than previously thought. What's important about that date, about 770,000 years ago, is that this was an ice age on Earth.

　　Over Earth's long history, there have been a number of times when ice and snow covered a large part of its surface. Such periods are known as ice ages.

　　Earth is in an ice age now. It started about 2 million years ago. Despite the many warm periods since then, scientists regard the whole time as one ice age because of the continuous existence of at least one large ice sheet—the one over Antarctica.

　　The new discovery was made by Chinese and US scientists. It suggests Peking Man is probably our oldest cold weather human being, said Darryl Granger, an atmospheric scientist at Purdue University whose research appears in Thursday's edition of the journal Nature.

　　The average yearly temperature at the time in that part of China was around the freezing mark, but it was too dry for an ice sheet, Granger said.

　　This raises a question. How did Peking Man survive the cold weather?

　　Rick Potts, a Smithsonian Institution human origins expert who wasn't involved in the research, raised three possibilities：

　　First, fire. Early findings showed signs of a fire in Peking Man's cave. But there has been debate about whether the fire was accidental or controlled.

　　Second, fur. There is no evidence that Peking Man used simple tools to make more form-fitting clothes. It's more likely he wore animal fur.

　　Lastly, he may have developed gradually to handle the cold. Peking Man may have experienced physiological changes that allowed more blood to flow to his hands and legs, Potts said. “People in general who live in colder climates tend to be shorter and wider，” he explained.

　　Unlike the times of Peking Man, today the global temperature is rising due to the greenhouse effect. In the future, could humans develop to handle the warmth just as Peking Man did to fight the cold?

　　文章大意：最新研究發現北京人的年代應該是處于冰河世紀，比我們原先的估計早二十萬年。

　　1．According to the new research, Peking Man actually dates back to________.

　　A．around 500,000 years ago

　　B．over 200,000 years ago

　　C．about 770,000 years ago

　　D．about 2 million years ago

　　答案：C　細節理解題。由第二段最后一句話“What's important about that date, about 770,000 years ago, is that this was an ice age on Earth.”可知。

　　2．What is the most important standard for scientists to decide an ice age?

　　A．The weather conditions.

　　B．The continuous existence of any large ice sheets.

　　C．The average yearly temperature.

　　D．The long period of snowfall.

　　答案：B　推理判斷題。由第四段第三句話“...scientists regard the whole time as one ice age because of the continuous existence of at least one large ice sheet—the one over Antarctica.”可知。

　　3．Which of the following is TRUE of Peking Man?

　　A．He is the oldest human being.

　　B．He used fire to keep warm.

　　C．He wore form-fitting clothes made from fur with simple tools.

　　D．He might have been shorter and wider than previously thought.

　　答案：D　推理判斷題。由倒數第二段“People in general who live in colder climates tend to be shorter and wider”可推知，北京人可能比我們原先預計的要矮胖，這樣才能與當時的氣候相適應。

　　4．The passage can probably be found in________.

　　A．a history textbook

　　B．a scientific magazine

　　C．a research report

　　D．an entertainment newspaper

　　答案：B　推理判斷題。由全文文章大意可推知。

　　Anthropologists are scientists that study people who often lived hundreds or even thousands of years ago. Items those men, women, and children left behind when they died—everything from clothing to jewelry and tools—tells anthropologists a lot. And sometimes even their words survive.

　　Experts believe that a discovery in Mexico is the oldest example of writing ever found in America. The people who created it probably lived 3 000 years ago, long before Christopher Columbus arrived in the New World.

　　Workers digging in a rock mine happened to notice a stone block with marks carved onto its surface. They found the large piece of stone near the city of Cascajal, Mexico, which was once the capital of an ancient people called the Olmec.

　　“There are signs on the block that seem to show objects used by the Olmec during their religious ceremonies，” says Dr Stephen Houston, of Brown University in the US. “There is a sign that looks very similar to a knife and another that looks like the chair of a King，” he explains.

　　Houston, an expert on the writing systems of ancient cultures, says the discovery is exciting because “it makes clear that the Olmec could read and write. It is like hearing voices from the past.”

　　But experts don't know exactly what the writing says. Finding other examples of Olmec writing could help decipher_the_puzzle.

　　“We could have whole sets of ancient writing which will basically make ancient people speak to us directly，” says Houston. “There are many puzzles to be solved, and this is just one of them.”

　　文章大意：前不久專家在墨西哥發現了刻在石塊上的一種古老的文字，可能是一個叫Olmec的古老民族遺留下來的。但是由于樣本太少，目前還無法識別文字表示的內容。

　　5．According to the passage, what items do scientists often use to learn more about the past?

　　A. Clothing and jewelry.

　　B. Books and stones.

　　C. Knives and chairs.

　　D. Items ancient people left.

　　答案：D　細節理解題。根據第一段第二句可得知，過去遺留下來的東西可以作為借鑒。

　　6．What is important about the stone block mentioned in the passage?

　　A．It proves that people lived in this part of the world more than 3 000 years ago.

　　B．It allows scientists to translate the ancient language used in this area.

　　C．It is evidence of the oldest form of writing ever found in America.

　　D．It shows the people of the area have a written language.
