where dogs first began living sideside with humans are questions that have stirred hot debate among scientists. there are a few hard facts that all agree on. these include that dogs were once wolves and they were the first animal to be domesticated(驯养) by humans. they came into lives some 15，000 years ago, before the dawn of agriculture.beyond that, there is little agreement. the earliest bones found that are unquestionable dogs and not wolves date from 14，000 years ago. however, 30，000yearold skulls have been discovered in france and belgium that are not pure wolf and some scientists think could be dogs.with such puzzling evidence, many scientists are now turning to dna to find out when and where dogs were first domesticated. in one research project, tens of thousands of blood samples have been taken from street dogs around the world. the plan is to compare them with those of wolves. its even possible to analyse dna from ancient bones. tiny pieces of the 30，000yearold skulls mentioned earlier are currently being studied, and another dna study has already shown that ancient dogs preserved in the alaskan icefields evolved from asian wolves, not american ones.indeed, the ancient dna may turn out to be more informative than the dna of living dogs. because dogs have accompanied humans around the world for thousands of years, their current distribution may tell us very little of their origins. this is why different groups of scientists believe that dogs variously originated in eastern asia, mongolia, siberia, europe or africa.but why were the animals domesticated in the first place? the most recent theory is that dogs domesticated themselves, initially living in and around our ancient villages to eat any food thrown out. today, this is a way of life still shared by threequarters of a billion unowned dogs worldwide.5. which is the only statement generally agreed on by scientists studying dogs?a. they originally were used as farm animals.b. they evolved from wolves found in europe.c. they helped the development of agriculture.d. they were the first animal to be kept as pets.6. why does the writer first mention the 30，000yearold animals skulls?a. to show that dogs were much larger in the past.b. to prove that dogs developed from asian wolves.c. to suggest that dogs may have evolved much earlier.d. to argue that dogs were first kept in france and belgium.7. how did scientists determine the origins of the ancient dogs found in alaska?a. by examine the animals dna.b. by analyzing the age of their bones.c. by studying the shape of their skulls.d. by comparing them with modern dogs.8. why did dogs start living with humans?a. because they were attracted by food.b. because they were trapped by humans.c. because they couldnt survive in the wild.d. because they were trained to protect villages.【语篇解读】你曾经是否想过狗狗是在什么时候成为“人类最好的朋友”和“世界上最喜爱的宠物”的吗？这篇文章给你答案。5. d细节理解题。根据第一段第四句话和第五句话可知，有一些事实是专家们都认可的，那就是狗曾经是狼，是第一种被人驯养成宠物的动物。6.

think it is just another piece of useless technology. whatever (虚拟的) reality, is going to become a big part of our lives very soon. 2016 saw the introduction of many fancy products in the world of vr, including microsofts hololens and samsungs gear vr. all of them offer an exciting look at the new realities and opportunities that vr brings. these, however, are the early days of a technology that is expected to go from strength to strength. and 2017 looks like it is going to be the year in which vr technology really takes off. for a start, using vr will become more normal in 2017. microsoft and intel have already discussed their plans for simpler and less expensive vr headsets. “the idea of vr will stop being a scifi (sciencefiction) idea, and instead it will turn into an industry of real products used as ways to show off imagination.”said andrew, a designer at us vr company, survios. it is also expected that vr products will play a part in more common and reallife fields like fashion and film. for example, to enjoy the atmosphere and energy of the front row experience at a fashion show, fans will no longer have to go along in_the_flesh. instead people will be able to enjoy the experience by just wearing a vr headset at home. you can also expect vr mirrors and fittingrooms sooner rather than later. “this is an especially good opportunity for brands looking to offer very personalized experiences.”said roy deyoung from usbased marketing agency, pmx. as time goes on, there will be less discussion about whether people will accept vr technology. it will simply be a discussion of when. 9. why do many shopping malls have areas for vr experiences?a. to collect shoppers opinions. b. to meet the demands of shoppers. c. to entertain shoppers with new technology. d. to

landscapes to create art, taking art out of the museum and into the outside world. modern land art movement really got going in the 1960s, when american artists began creating land art on a large scale. today, works of modern land art can be seen all over the world, sometimes right alongside much older pieces of land art created by people who lived thousands of years ago.land art, which is not necessarily unchangeable, can take a number of forms. for example, in 1970 robert smithson created the spiral jetty (螺旋状防波堤), made of a collection of stones and mud, in the great salt lake. the american artist made a large jetty in a spiral shape which sticks out into the waters of the lake.reshaping the landscape is a common characteristic of land art, which can be created by moving parts around. people can also add things to the environment to create land art, like salt, which is added to the spiral jetty. it is possible to use plants. in all cases, land art is immovable.land art is designed to gradually form, change, and eventually decay (衰落). thats one of the biggest differences between land art and most of the art one sees in the museums. some works of art can exist only for a few hours or days. others are exposed to rain and wind so that they develop and decay over time, which is part of the attractiveness in the eyes of the artists.13. what can be learned from the first paragraph?a. land art was the most popular art in the 1960s.b. land art aims to get people interested in nature.c. american artists were the first to create land art.d. people have been creating land

creating land art.15. one of the unique characteristics of land art lies in_a. it shows the extreme beauty of natureb. it develops and decays gradually over timec. it combines the landscapes around

health care is regarded as an important way to improve the health and wellbeing of people around the world. in many countries of the world, free health care is provided by the government. _16_clearly,
