Dogs were living as companions to the early settlers of North America over 10,000 years ago.

The oldest domestic dogs in the Americas were thought to be around 9500 years old. Angela Perri of Durham University, UK, and her colleagues have carried out fresh radiocarbon dating on the two dog skeletons that gave this date, discovered in the prehistoric Koster site in Illinois, and found they were even older: around 10,100 years old.

A third dog from another Illinois site called Stilwell II was older still，at 10,190 years old. That makes it the oldest known domesticated dog in the Americas.

The team concluded that all three dogs were domesticated as their skeletons were complete and unskinned, and so hadn’t been butchered for food. They had also been carefolly buried, evidence they were valued by their owners. The Stilwell II dog, which probably resembled a small English settler, was under what seemed to be the floor of a living area.

It is unclear why it took so long for tame dogs to arrive in the Americas, given that they were domesticated at least 14,000 years ago in Eurasia. By this time, people were already moving into North America from Siberia; there is evidence some reached Chile 18,500 years ago. Geneticists have found signs of at least three waves of migration over the following millennia. There is no evidence that domestic dogs accompanied them.

“We don’t know if dogs were part of the first waves of immigration to the Americas” says Luc Janssens of Ghent University in Belgium. “It could be so, but no archaeological bones have yet been found.”

It is “overwhelmingly probable” that some of the early settlers did bring dogs to the Americas, but they may not have had “the time or the spiritual compulsion to bury them’％ says Pat Shipman of Pennsylvania State University.

1.How old is the oldest known domestic dog in the Americas?

A. About 9500 years.　　 B. About 10,100 years.

C. 10,190 years.　　 D. 18,500 years.

2.The underlined word “butchered” in the fourth paragraph could be replaced by .

A. killed　　 B. bought

C. trained　　 D. raised

3.What is the attitude towards when tame dogs arrived in the Americas in the last three paragraphs?

A. Undoubted.　　 B. Unsure.

C. Indifferent.　　 D. Unconfident.

4.What is the main topic of this passage?

A. The earliest domestic dog in the Americas.

Some people say that dogs are human’s best friend-good companions, loyal and lovable. Of course, they can be more than just a pet as some are excellent working dogs. More recently, a new role has been found for the animals-working as therapy dogs in universities.

Research, conducted by Washington State University, has found that spending time with dogs can help stressed-out students. Patricia Pendry from the university said that a study of 300 undergraduates had found weekly hour-long sessions with dogs brought to the university by professional handlers (训狗师) had made stressed students who were at “high risk of academic failure” or dropping out, “feel relaxed and accepted”. The dogs helped them to concentrate, learn and remember information.

Other research has shown that petting animals like dogs can reduce stress hormone levels and anxiety. Around 1,000 campuses in the US already use therapy pets and it’s becoming more common in the UK. For example, The University of Middlesex has employed some dogs to help stop lonely students dropping out. Fiona Suthers, head of clinical skills at the university, says that five Labradors had a “stringent assessment” to ensure they had the right temperament (性情). But she adds, “It’s hard to describe the impact of just having a dog lying down in the corner of a class.”

Using dogs for therapy can also help the dogs themselves. In Wales, Swansea University Students’ Union has used rescued Greyhounds to help students unwind between exams. Sessions allow mistreated and abandoned dogs to interact with humans and begin to trust them again. Student Union education officer Chloe Hutchinson said, “A lot of students have dogs at home and might be a bit homesick, especially around exam time when it is stressful and you just want your home comforts.”

So if you’re a student who’s been working like a dog, but you still feel like you haven’t a dog’s chance in passing your exams, maybe introducing a four-legged friend into your life might be the help you need.

1.What can we learn about therapy dogs in universities?

A.They can reduce students’ anxiety.

B.They can help blind students.

C.They can work with students.

D.They can keep students safe.

2.What does Fiona Suthers imply?

A.Dogs play a part in class in universities.

B.The right temperament is needed for a therapy dog.

C.The impact of therapy dogs is clear.

D.It’s hard to describe how dogs will help with the students.

3.How do the abandoned dogs themselves get help?

A.By finding a new family to live in.

B.By helping students with some exams.

C.By lying down to the ground in a room.

D.By making more chances to meet humans.

4.What is the best title for the text?

A.Dogs helping stressed-out students

B.College students are stressed out

C.Why dogs are perfect helpers

D.How to keep a therapy dog

In the eyes of dog lovers, the dog is man’s best friend. But for much wildlife, loose dogs may be a dangerous enemy, according to a study by a biologist from Utah State University in the US.

Based on much existing research and their own case studies, Julie Young of Utah State University and four other scientists conclude that loose dogs may represent a huge danger to wildlife, especially endangered species, by hunting down or worrying them and by spreading diseases. They also found that dogs, their worldwide numbers around 500 million, can cause more damage to wildlife and livestock(牲畜) than wolves and other enemies of these animals.

Young gave examples from the US state of Idaho, where research showed the presence of dogs reducing some deer populations. On the Navajo American Indians’ reservation in northeastern Arizona, packs of loose dogs are chasing livestock. They have killed populations of small animals such as rabbits and act as a disease carrier for rabies(狂犬病) among people and other animals, she said. Loose dogs also were to blame for distemper outbreak leading to a die-off of endangered black-footed ferrets in northwestern Wyoming in the 1980s.

The phenomenon is not just limited to US; it’s a global problen. Julie Young once studied three endangered species in central Asia: wild sheep, gazelles and antelope. The rate of injury and death to these animals by loose dogs was very high. In another case, Young found that dogs, not wolves, as originally suspected, were responsible for a large number of livestock killings in the mountainous Basque country between Spain and France.

Authors of the new study said the problem is likely to worsen as communities expand. Then how to deal with it?

Indeed, in many countries, leash(拴狗的皮带) laws permit punishment of dog owners whose pets chase wildlife. But lawbreakers are rarely punished because the police lack both people and money.

Young has low-cost solutions to the problem for dog lovers, though. They include public dog-training programs and vaccinating (预防接种) dogs against rabies and other illnesses.

1.. What is the main point of Julie Young’s study?

2.. Which of the following statements about loose dogs is TRUE according to the research?

3.. Which of the following is among Julie Young’s solutions to the trouble caused by loose dogs?

4.. What is the main point of the article?

A 90-year-old may not be typical for a show's narrator（解说员）,but without the voice of English broadcaster Sir David Attenborough,one of the most successful new shows on television just wouldn't be the same.

BBC's Planet EarthⅡis getting good ratings in the United Kingdom.And Sir David,the man behind the show's voice,describes it as "greatly pleasing".The naturalist is the father of nature documentaries（纪录片）,with a television career that started in 1950.Since then,the London-born broadcaster has traveled the world intent on sharing his discoveries through the television in new ways.

Ever since his first wildlife documentary series,1954's Zoo Quest,Sir David's voice has become synonymous（同义）with environmental protection.Concerned with how humans are harming the planet,he attempts to educate viewers on the threats and dangers that are present today.He's used his profile to raise important issues like global warming,deforestation,climate change and overpopulation.

"We can't go on increasing at the rate human beings are increasing forever,because the Earth is finite（有限）and you can't put infinity into something that is finite,"he told The Independent two years ago."So if we don't do something about it then the world will do something about it."

And after almost 30 years of nature-based programming,Sir David's efforts to protect wildlife and the environment have not gone unnoticed.His work has been significant in reconnecting an increasingly disconnected human population with the environment of the planet that we not only come from but also rely on.

1.What can we learn about Planet EarthⅡ?

A. It was made in 1950.

B. It is now very popular.

C. It is broadcast all over the world.

D. It was filmed in the United Kingdom.

2.When did Sir David's job begin to be widely recognized?

A. In 1950.

B. In 1954.

C. When he is 90 years old.

D. After 30 years of hard work.

3.What does Sir David intend to tell in Paragraph 4?

A. We will lose control of the worsening of the Earth.

B. He will help to deal with some important issues.

C. Measures should be taken to protect the Earth.

D. Human population should stop increasing.

4.Which of the following best describes Sir David according to the text?
