    Humans have been keeping animals as pets for tens of thousands of years, but Dr. Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.

    “Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”

    This may not sit well with pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don’t have to feed it, you don’t have to walk it, it won’t make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.

    It’s not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It’s the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.

    As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn’t need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.

    So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn’t have a heartbeat might not be a far-fetched dream.

    1.What does the underlined phrase “sit well with” means?

    A. be refused by B. be beneficial to

    C. make a difference to D. receive support from

    2.What are the advantages of robot pets?

    a. They are plastic and feel smooth.

    b. Owners needn’t worry about them when going out.

    c. They can help cure allergies.

    d. They save space and costs.

    A. ab B. bc C. bd D.cd

    3.We can learn from the passage that___________.

    A. Sony is the first company to produce robot pets Aibo.

    B. People can develop strong bond with their robot pets.

    C. Rault thinks robot pets still have a long way to go.

    D. Robot toys may help people care more about living beings.

    4.The passage mainly tells us___________.

    A. the advantages of robot toys

    B. the popularity of robot pets

    C. living pets are dying out.

    D. robot pets are coming.

    Too often young people get themselves employed quite by accident, not knowing what lies in the way of opportunity for promotion, happiness and security. As a result, they are employed in doing jobs that afford them little or no satisfaction.

    Our school leavers face so much competition that they seldom care what they do as long as they can earn a living. Some stay long at a job and learn to like it; others leave one for another looking for something to suit them. The young graduates who leave the university look for jobs that offer a salary up to their expectation.

    Very few go out into the world knowing exactly what they want and realizing their own abilities. The reason behind all this confusion is that there never has been a proper vocational (职业的) guidance in our educational institution. Nearly allfeel their way in the dark. Their chief concern when they lookfor a job is to ask what salary is like. They never bother tothink whether they are suited for the job or, even more important, whether the job suits them. Having a job is more thanmerely providing yourself and your dependants (受赡养者)with daily bread and some money for leisure and entertainment.It sets a pattern of life and, in many ways, determines social status in life, selection of friends, leisure and interest.

    In choosing a profession you should first consider the type of work which will suit your interest. Nothing is more sad than taking on a job in which you have no interest, for it will not only ruin your talents but also discourage your desire to succeed in life.

    1.Few school leavers have plans for the long term when finding jobs because ________.

    A. they are lowly paid

    B. they are not well trained

    C. it is difficult to get employed

    D. they don't know what they are interested in

    2.According to the passage, the difficulty in choosing a suitable job mainly lies in that ________.

    A. much competition has to be faced

    B. many employees have no working experience

    C. the young people only care about how much they can earn

    D. schools fail to offer students appropriate vocational guidance

    3.In the writer's opinion, which of the following statements is most important?

    A. Your job must suit your interest.

    B. Your job must set a pattern of life.

    C. Your job must offer you a high salary.

    D. Your job must not ruin your talents.

    根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    If you think about your circle of friends and family members, you can certainly pick out one or more people who are not good listeners. 1. If you’re fortunate, that person is a good friend, a loved one or a teacher.

    All too often, we associate the benefits of good listening skills with achieving very specific outcomes, like following the boss’s orders (aimed at getting a job promotion).

    2. We think of them as something basic, which we mastered in our formal schooling, along with dictation and obeying instructions, etc. This is a shame. We should know listening skills are the focus of lifetime learning and development, related to our communication skills.

    3. All of these occur because two people or groups don’t listen to each other. We don’t analyze the root problem, or work on improvement steps.

    We still tend to treat listening skills the way we treat learning to walk: we think that once we’ve acquired them, we’ve got them. We are ready to move on to the next thing. Wrong. 4.

    Poor listening skills often damage effective dialogue between people. 5. If we were able to reduce misunderstandings in our conversations by 20-30%, there would be benefits in efficiency and the elimination (消除) of tiresome repetition.

    A. However, think about the upside potential.

    B. We’re surrounded by this kind of outcome.

    C. We tend to undervalue the importance of our listening skills.

    D. Think about the number of failures, misunderstandings and arguments.

    E. Equally you can think of someone you know who is a very good listener.

    F. The challenge of listening is determining when the speaker wants a response or advice.

    G. The problem is that people and language are far more complex than the roads we travel on.

    What are the biggest problems that society will have to deal with in the new age? There are diseases like AIDS and cancer. There’s climate change, of course. And what about producing enough cheap food and energy for the world’s growing population? Who’s going to solve all these terrible problems? Yes, politicians and world leaders will have a big part to play. Yes, businesses will need to create the economic wealth to pay for some of these things.

Forensic(法医的) scientists work with the police to find quite small clues to catch criminals.

You could be a food technologist helping to keep fruit and vegetables fresher for longer. Perhaps sport is your thing? Do you know that most top athletes work with sports scientists in order to improve their performance? You could even be the science writer who gets to spend the life studying the latest advances and sharing them with the world.
