The Maya were an intelligent, culturally rich people whose achievements were many. They had farms, beautiful palaces, and cities with many buildings. The Mayan people knew a lot about nature and the world around them. This knowledge helped them to live a better life than most people of that time, because they could use it to make their lives more comfortable and rewarding. Knowledge about tools and farming, for instance, made their work easier and more productive.In ancient Mexico there were many small clearings in the forest. In each clearing was a village with fields of corn, beans, and other crops around it. To clear the land for farms, the Maya cut down trees with stone axes. They planted seeds by digging holes in the ground with pointed sticks. A farmer was able to grow crops that produced food for several people. But not every Maya had to be a farmer. Some were cloth makers, builders, or priests.The Maya believed in many gods, including rain gods, sun gods, and corn gods. The people built large temples to honor the Mayan gods. Skillful workers built cities around these temples. It was difficult for them to construct these cities, because they had no horses to carry the heavy stone they used to build with. Workers had to carry all of the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing.Although the cities that the Maya built were beautiful, and the people worked hard to build them, very few of the people lived in them. Usually, only the priests lived in the cities.The other people lived in small villages in the forests. Their houses were much simpler than the elaborate structures in the cities. They lived in small huts with no windows. The walls were made of poles covered with dried mud, and the roof was made of grass or leaves. Most Maya lived a simple life close to nature.Measuring time was important to the Maya, so they developed a system for measuring it accurately. Farmers needed to know when to plant and harvest their crops. Mayan priests made a system to keep track of time. They wrote numbers as dots (.) and bars (-). A dot was one and a bar was five.The Mayan priests studied the Sun, Moon, stars, and planets. They made a calendar from what they learned. The year was divided into 18 months of 20 days each with five days left over. The Mayan calendar was far more accurate than the European calendars of the time.Around the year 800, the Maya left their villages and beautiful cities, never to return. No one knows why this happened. They may have died from an infectious disease. They may have left because the soil could no longer grow crops. Archaeologists are still trying to find the lost secrets of the Maya. They are still one of our greatest mysteries.41. According to the passage, what made the Mayan peoples life easier?A. Their knowledge about nature and the world.B. The arrival of the Spanish.C. The location of their villages and cities.D. The gods they believed in.42. Which of the following is not true about the Maya?A. Religion was an important part of the Mayan culture.B. The Maya led a simple and natural life.C. Most Mayans lived in the cities they built.D. Tools made the Mayans farming easier and more productive.43. What numbers do“ . . ”and “ ” represent respectively?A. 2；3 B. 10；3 C. 2； 15 D. 10；1544. The elaborate structures in the cities _.A. were complex and consisted of many parts B. didnt have much decorationC. were small but very cozyD. were made of modern materials 45. What is the main idea of this passage?A. The Mayan calendar was more accurate than the European calendar.B. The Maya were an intelligent, culturally rich people with many achievements.C. The mysteries of the Maya.D. How did the Mayan develop their agriculture?BBelow is a selection from a science website: http:/www.genome.gov/25020028 What is cloning?The term cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity(存在体). The copied material, which has the same genetic makeup as the original, is referred to as a clone.How are genes cloned?Researchers routinely use cloning techniques to make copies of genes that they wish to study. The procedure consists of inserting a gene from one organism, often referred to as "foreign DNA," into the genetic material of a carrier called a vector(带菌者). Examples of vectors include bacteria, yeast cells or viruses. After the gene is inserted, the vector is placed in laboratory conditions that prompt it to multiply, resulting in the gene being copied many times over.What animals have been cloned?Over the last 50 years, scientists have conducted cloning experiments in a wide range of animals using a variety of techniques. In 1979, researchers produced the first genetically identical mice by splitting mouse embryos in the test tube and then implanting the resulting embryos into the wombs of adult female mice. It was not until 1996, however, that researchers succeeded in cloning the first mammal from a mature cell taken from an adult animal. After 276 attempts, Scottish researchers finally produced Dolly, the lamb from the udder cell of a 6-year-old sheep. Besides, other mammals that have been cloned include: cat, deer, dog, horse, mule, ox, rabbit and rat.Have humans been cloned?Despite several highly publicized claims, human cloning still appears to be fiction. There currently is no solid scientific evidence that anyone has cloned human embryos.In 1998, scientists in South Korea claimed to have successfully cloned a human embryo, but said the experiment was interrupted very early when the clone was just a group of four cells.In 2004, a group led by Woo-Suk Hwang of Seoul National University in South Korea published a paper in the journal Science in which it claimed to have created a cloned human embryo in a test tube. However, an independent scientific committee later found no proof to support the claim and, in January 2006, Science announced that Hwang's paper had been retracted(撤销).Why is human cloning difficult? From a technical perspective, cloning humans and other primates（灵长类动物） is more difficult than in other mammals. One reason is that two proteins essential to cell division are located very close to the chromosomes（染色体） in primate eggs. Consequently, removal of the egg's nucleus to make room for the donor nucleus also removes the proteins, interfering with cell division. In other mammals, such as cats, rabbits and mice, the two proteins are spread throughout the egg. So, removal of the egg's nucleus does not result in loss of proteins. In addition, some dyes and the ultraviolet light used to remove the egg's nucleus can damage the primate cell and prevent it from growing.What are some of the ethical issues related to cloning?Cloning would present the potential of creating a human that is genetically identical to another person who has previously existed or who still exists. This may conflict with long-standing religious and societal values about human dignity, possibly violating principles of individual freedom, identity and autonomy（自主权）. However, some argue that cloning could help sterile(生育困难的) couples fulfill their dream of parenthood. Others see human cloning as a way to avoid passing on a hurtful gene that runs in the family without having to under
