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

   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

   D. early people understood environmental protection

64---67    CBAC  


解析:

64.解析:這是一道細(xì)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(duì)動(dòng)物的數(shù)量影響不大。

65.解析:這是一道細(xì)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(gè)詞就說明了幾個(gè)家族聚集在一起形成更大的群體是為了保護(hù)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(dòng)物或?qū)ふ倚碌闹参锷L(zhǎng)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(huì)發(fā)展各階段對(duì)環(huán)境的影響,最初人的群體小,能力低,所以對(duì)環(huán)境影響小,隨著人類群體的擴(kuò)大和現(xiàn)代文明的產(chǎn)生,對(duì)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。

  On July 16, 1960, Jane Goodall, a 26-year-old former secretary from England, began to study the behaviour of chimpanzees in the wild.Until that time, scientists had mostly observed and studied chimpanzees in laboratories and zoos.Few scientists had gone to study chimpanzees in the remote areas of Africa where the chimps live.When scientists had studied the chimpanzees in the wild, they hadn’t spent long periods of time observing them.Jane Goodall planned to watch chimpanzees in Africa over a ten-year period and see exactly how they behaved.She was not a professional scientist when she started out.Her book, In the Shadow of Man, tells how she began her project and what she discovered.As Goodall said in 1973, “I had no qualifications at all.I was just somebody with love of animals.”Her love of animals drew her to Africa where she met Dr.Louis S.B.Leakey.

  Leakey was a world-famous scientist who was studying how prehistoric people lived.Since chimpanzees are humans’ closest living relatives, Leakey thought prehistoric people might have lived in the same ways that chimps live today.Leakey told Goodall that studying chimps might give clues about the way that early people lived.Leakey asked Goodall to study the chimps on the shores of Lake Tanganyika in Africa.The chimps were very shy and the country was very difficult to travel through.Goodall took on the difficult job of finding and watching the chimpanzees.

  Stonehenge(巨石陣)is the most famous of the stone circles of the British Islands for its unusual engineering.It is good in condition, so it is a good example to study.Built in 2800 B.C., Stonehenge shows that early people were very good at problem-solving and organization.The builders of Stonehenge had to figure out how to build it without modern machines.They also had to organize the work of hundreds, perhaps thousands, of workers to build it.

  First they had to carve the stones.Then, they had to transport the heavy stones(up to four tons!)twenty kilometers to Stonehenge.The next task was to stand the stones up.The most difficult task was putting the top stones in place.Each one of these tasks took a lot of planning and a lot of strength, but the workers of Stonehenge were excellent builders.

  Why did these people work so hard to build Stonehenge? Researchers believe that Stonehenge is a huge calendar.Certain stones mark the location of the rising and setting moon in midwinter.Other stones mark the rising and setting sun in midsummer.The ancient people held religious ceremonies on these days.These ceremonies probably asked the gods to bring good weather for crops and to protect the people from bad weather.

  As a historical site, Stonehenge is an engineering success.Thousands of years later, it still stands.As a calendar, Stonehenge is very accurate.It shows that early people had a deep understanding of astronomy(天文學(xué))and the movements of the sun and the moon.They didn’t have machines or computers, but Stonehenge shows people could do many things using only their muscles and their brains.

[  ]

A.

About 2000 years.

B.

About 2800 years.

 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.”

1. The underlined word “remains” is closed in meaning to ______.

A. leftover food     B. animal waste

C. dead bodies    D. living environment

2. According to the study described in Paragraph 4, we can learn that ______.

A. ancient dogs entered North America between 1450 and 1675 AD

B. the 11 bones of ancient dogs are not from native American dogs

C. the bones discovered by the gold miners were from North American wolves

D. the bones studied were not from dogs brought into North America by Europeans

3. What can we know from the passage?

A. Native Americans domesticated local wolves into dogs.

B. Scientists discovered some ancient dog remains in 1920s.

C. Latin America’s dogs are different from North America’s in genes.

D. Ancient dogs entered North America across the Bering Land Bridge.

4. The first humans into the New World brought dogs along with them because ______.

A. dogs fed on mice                    B. dogs were easy to keep

C. dogs helped protect their resources      D. dogs could provide excellent service

5.What does the passage mainly talk about ______.

A. the origin of the North American dogs

B. the DNA study of ancient dogs in America

C. the reasons why early people entered America

D. the difference between Asian and American dogs
