Early people had very little effect on the environment. They lived in caves in very small ‘clan’groups. They collected or killed only enough for the clan’s survival. Early clans were nomadic, which means that they did not stay in one place. Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to protect the environment. The land had time to recover and animals had time to breed (繁殖) before the clan returned for the next season.
As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually , people tamed(馴養(yǎng)) wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.
Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so they began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.
People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also gave people more free time. So art, dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.
Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.
However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.
64. Early tribes didn't have much effect on animal population because __ .
A. they kept animals for themselves B. they ate only vegetables
C. they killed only enough for food D. they loved animals
65. The main purpose for small clans to join together was .
A. to hunt animals B. to seek safety C. to share caves D. to protect environment
66. Which of the following is TRUE according to this passage?
A. Early people moved to new places looking for new sources of food.
B. Modem civilization began when people started to live together in big groups.
C. Modem advancements are always good for the environment.
D. People began to exchange goods because they didn't have enough money.
67. It can be concluded from the passage that .
A. human progress has brought civilization to the society
B. civilization has improved traditional forms of work
C. our environment has been affected by human progress
D. early people understood environmental protection
64---67 CBAC
64．解析：這是一道細節(jié)推斷題。從第一段第3句“They collected or killed only enough for the clan’s survival”可知他們僅僅捕獵夠吃的食物就夠了，所以對動物的數(shù)量影響不大。
65．解析：這是一道細節(jié)推斷題。根據(jù)第二段第一句“As time went by, these small family clans joined with oters to form larger group for protection.”protection這個詞就說明了幾個家族聚集在一起形成更大的群體是為了保護自己，也就是尋求安全，選B.
66．解析：這是一道判斷正誤題。從第一段第三行“Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild.”可知人們遷徙主要是跟隨野生動物或?qū)ふ倚碌闹参锷L的地區(qū)，選A。
67．解析：這是一道結(jié)論歸納題。這篇文章主要介紹人類社會發(fā)展各階段對環(huán)境的影響，最初人的群體小，能力低，所以對環(huán)境影響小，隨著人類群體的擴大和現(xiàn)代文明的產(chǎn)生，對環(huán)境影響越來越大。從最后一段“However, pollution and other serious problems have also resulted from human progress.”說明環(huán)境還是收到了影響。

When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science.
Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material—some of it unearthed by miners in Alaska—to conclude that today’s domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man’s best friend may have enabled the tough journey from Asia into North America. “Dogs may have been the reason people made it across the land bridge,” said Wayne. “They can pull things, carry things, defend you from fierce animals, and they’re useful to eat.”
Researchers have agreed that today’s dog is the result of the domestication(馴化) of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America’s domestic dog was that Natives domesticated local wolves, the descendents(后代) of which now live with people in Alaska, Canada, and the Lower 48.
Dog remains from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost(永凍層) until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of “pure native American dogs,” Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America.
Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens(標(biāo)本) from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge.
Leonard and Wayne’s study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. “Dogs must have been useful because they were expensive to keep,” Wayne said. “They didn’t feed on mice; they fed on meat, which was a very guarded resource.”
