The dodo is among the most famous extinct creatures, and a poster child for human-caused extinction events. Despite its bad name, and the fact that the species was alive during recorded human history, little is actually known about how this animal lived, looked, and behaved. A new study of the only known complete skeleton(骨架) from a single bird takes advantage of modern 3-D laser scanning(扫描) technology to open a new window into the life of this famous extinct bird.
The study was presented at the 74th Annual Meeting of the Society of Vertebrate Paleontology in Estrel, Berlin. Leon Claessens, Associate Professor at the College of the Holy Cross, and lead researcher on the study said that, "the 3-D laser surface scans we made of the fragile dodo skeletons enable us to reconstruct how the dodo walked, moved and lived to a level of detail that has never been possible before. There are so many outstanding questions about the dodo bird that we can answer with this new knowledge."
A complete dodo skeleton, found by an amateur collector and barber, Etienne Thirioux, on the island of Mauritius between 1899 and 1917, has remained unstudied, even though it is the only complete dodo skeleton from a single individual bird known to exist. All other skeletons are incomplete combinations, meaning that they are gathered from more than one individual. In addition, Thirioux constructed a second, partially combined skeleton, which contains many bones that also belong to a single bird. "Being able to examine the skeleton of a single, individual dodo, which is not made up from as many individual birds as there are bones, as is the case in all those other combined skeletons, truly allows us to appreciate the way the dodo looked and see how tall or fat it really was," said Juilan Hume, of the Natural History Museum UK, a co-author on the study.
The scans were performed on site in Durban, South Africa, and allow examination of the biology of this mysterious extinct bird in detail for the first time. Using the newest digital tools and techniques, the scans provide an insight into how the flightless dodo may have developed its giant size, and how it walked and lived in its forest home. According to Kenneth Rijsdijk, a biologist from University of Amsterdam, “the skull of the dodo is so large and its mouth so strong that it is easy to understand that the earliest naturalists thought it was related to sharks and other birds of prey（猛禽）, rather than the pigeon family.”The underlined phrase “a poster child” in Para. 1 is closest in meaning to “ ”.

In one way of thinking, failure is a part of life. In another way, failure may be a way towards success. The “spider story” is often told. Robert Bruce, leader of the Scots in the 13th century, was hiding in a cave from the English. He watched a spider spinning a web（蜘蛛织网）. The spider tried to reach across a rough place in the rock. He tried six times without success. On the seventh time he made it and went on to spin his web. Bruce is said to have taken heart and to have gone on to defeat the English… Edison, the inventor of the light bulb, made hundreds of models that failed before he found the right way to make one.
So what? First, always think about your failure. What caused it? Were conditions right? Were you in top from yourself? What can you change so things will go right next time?
Second, is the goal（目标）you’re trying to reach the right one? Try to do some thinking about what your real goals may be. Think about his question, “If I do succeed in this, where will it get me?” This may help you prevent failure in things you shouldn’t be doing anyway.
The third thing to bear in mind about failure is that it’s a part of life. Learn to “live with yourself” even though you may have failed. Remember, “You can’t win them all.”This passage deals with two sides of failure. In paragraph 1, the author talks mainly about __.
| A．the value of failure |
| B．how people would fail |
| C．famous failures |
| D．the cause of failure |
The underlined phrase “made it” means ______ .
| A．succeeded |
| B．failed |
| C．gave |
| D．got |
The lesson the spider taught Robert Bruce seems ______ .
| A．productive |
| B．straight forward |
| C．sorrowful |
| D．deep |
The author tells you to do all things except ______ .
| A．The think about the cause of your failure |
| B．to check out whether your goals are right for you |
| C．to consider failure as a part or life |
| D．to bear in mind that you will never fail in your life |
Which of the following is NOT true?
| A．Bruce and Edison were successful examples. |
| B．Failure may be regarded as a way toward success. |
| C．Edison learned a lot from the lesson the spider taught Robert Bruce. |
| D．One may often raise a question whether his goals are worth attempting. |
The greatest recent changes have been in the lives of women, during the twentieth century there was an unusual shortening of the time of a woman’s life spent in caring for children. A woman marrying at the end of the 19th century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, chance and health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty five and is likely to take paid work until retirement at sixty. Even while she has the care of children, her work is lightened by household appliances （家用电器）and convenience foods.
This important change in women’s way of life has only recently begun to have its full effect on women’s economic position. Even a few years ago most girls left school at the first opportunity and most of them took a full time job. However, when they married, they usually left work at once and never returned to it. Today the school leaving age is sixteen, many girls stay at school after that age, and though women tend to marry younger, more married women stay at work at least until shortly before their first child is born. Very many more afterwards, return to full or part-time work. Such changes have led to a new relationship in marriage, with both husband and wife accepting a greater share of the duties and satisfaction of family life, and with both husband and wife sharing more equally in providing the money and running the home, according to the abilities and interest of each them.According to the passage, around the year1990 most women married.
| A．at about twenty five | B．in their early fifties |
| C．as soon as possible after they were fifteen | D．at any age from fifteen to forty five |
We are told that in an average family about1990.
| A．many children died before they were five |
| B．the youngest child would be fifteen |
| C．seven of eight children lived to be more than five |
| D．four of five children died when they were five. |
When she was over fifty, the late 19th century mother.
| A．would expect to work until she died |
| B．was usually expected to take up paid employment |
| C．would be healthy enough to take up paid employment. |
| D．was unlikely to find a job. |
Many girls, the passage says, are now likely to.
| A．marry so that they can get a job |
| B．Leave school as soon as they can |
| C．give up their jobs for good after they are married |
| D．continue working until they are going to have a baby |
According to the passage, it is now quite usual for women to.
| A．stay at hone after leaving school |
| B．marry men younger than themselves |
| C．start working again later in life |
| D．Marry while still at school |
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 Basq
ue 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.What is the main point of Julie Young’s study?
A. Many species are endangered because they are killed by loose dogs.
B. Wild dogs are immune to many diseases.
C
. Wolves are still the greatest enemy of livestock.
D. Loose dogs pose a great danger to wildlife. Which of the following statements about loose dogs is TRUE according to the research?
| A．There are around 500 million loose dogs around the world. |
| B．The black-footed ferrets in northwestern Wyoming were once the main food source of local loose dogs. |
| C．The problem caused by loose dogs is the most serious in the US. |
| D．People used to think that wolves, rather than loose dogs killed livestock in the Basque country. |
Which of the following is among Julie Young’s solutions to the trouble caused by loose dogs?
| A．More strict leash laws |
| B．Public dog-training programs. |
| C．Vaccinating people against rabies and other illnesses. |
| D．More support from the police. |
What is the main point of the article?
| A．A global disaster caused by loose dogs. |
| B．What makes the dog man’s greatest friend. |
| C．The problem of loose dogs and the possible solutions. |
D．The dan ger of the increasing numbers of dogs. |
I was working with a client who was completely burned out on her career and life and then ready for a career change. As we were talking, she said, “I just wish I had meaningful work. I don’t feel like I am making a difference. I am just wasting my life.” This is the theme I hear most often from clients who have been in the workforce awhile.All of us want to feel like we are making a difference. We want to believe our work means something. The problem comes in defining “meaningful work”. What is it? That answer is different for everyone. For some meaningful work might be helping others organize their office. For others it may mean making a million dollars.
What really matters is how you see it. What is meaningful work to you? Take out a piece of paper and answer these questions. How do you define meaningful work? When do you feel like you are really making a difference? What work have you done so far that feels the most meaningful? Write down whatever comes to mind.
What you want to do is meaningful. It is very easy to start judging yourself as being selfish. Stop! Allow yourself to be honest. The fact is when Picasso painted; he was doing it because he liked to paint. He was not thinking, “Oh, I
hope this brings joy to others’ lives.” He painted because he wanted to. When Beethoven composed, he did it because he loved music. Even scientists searching for a c
ure for cancer are immersed in their work because it fascinates them.
Don’t look down on your work. It is easy to downplay the impor
tance of work that feels meaningful. I remember Tony Robbins told a story of talking with the owner of a major company. The man said to Tony, “I wish I could do what you do because it makes
such adifference in people’s lives”. Tony said, “You have got to be kidding! Look at what adifference you make. You provide work, health insurance and security for thousands ofpeople!” Don’t underestimate the value you provide.
Take a look at what you have written about meaningful work. Do you see any themes? How do you wish to contribute to this world? Whatever you choose, remember that the greatest gift you can give is to find work that makes you feel fulfilled and delighted. Respect your preference because giving your gifts to the world, whatever they look like, is the most meaningful action you can ever take.What does the writer mean by mentioning the famous people?
| A．Famous people are selfish to start work for themselves. |
| B．Doing meaningful work requires our interest in it. |
| C．Interest is the best teacher in learning. |
| D．Honesty makes for the greatest people. |
When you downplay the value of your work, you tend to think it is ______.
| A．quite different | B．very successful | C．not meaningful | D．less important |
According to the passage, what meaningful job does the writer advise us to take?
| A．The one which is popular in society. | B．The one which brings you profits. |
| C．The one which wins you fame. | D．The one which interests you |
The article is intended to ________.
| A．explain what is the most important in changing one’s job |
| B．advise taking an immediate action to find meaningful work |
| C．suggest we should show confidence and talent in work |
| D．tell us the problem that the author’s client met |
There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.
In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are strictly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers.This is 
true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.
What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of skill, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the world and their insistence to the present that is amazing. In Egypt, the US, China,Japan and among the Arctic peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys reflect their surroundings.Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.
Because toys can be generally regarded as a kind of art form, they have not been affected by technological quick development that characterize inventions for adult use. The progress from the wheel to the ox-cart to the automobile is a direct line of ahievement. The progress from a rattle(拨浪鼓) used by a baby in 3000 BC to one used by a baby today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of times and subject to the limtations of available 
materials. The reason why the toys most boys play with are different from those that girls play with is that_________.
| A．their social roles are strictly determined |
| B．most boys would like to follow their fathers’ professions |
| C．boys like to play with their fathers while girls with their mothers |
| D．they like challenging activities |
Which of the following is the author’s view on the historical development of toys？
A．The making skills in toys has remained essentially uncha nged. |
| B．Toys have remained basically the same all through the centuries. |
| C．The toy industry has witnessed great improvement in technology in recent years. |
| D．Toys are playing an increasingly important role in shaping a child’s character. |
Regarded as a kind of art form, toys________.
| A．follow a direct line of achievement |
| B．also appeal greatly to adults |
| C．are not characterized by technological progress |
| D．reflect the pace of social progress |
The author uses the example of a rattle to show that________.
| A．in toy-making there is a continuity in the use of materials |
| B．even the simplest toys can reflect the progress of technology |
C．it often ta kes a long time to introduce new technology into toy-making |
| D．even a simple toy can mirror the artistic tastes of the time |
