   24. What made management of care toward elderly more difficult in the 1980s?

25. What does the speaker say about older people in England?

23. What does the speaker say about residential a对于万博manbetxnd community care?

22. What is one cause of the current crisis in care for the elderly in England?

Discrimination against older people has a long history. Additionally, those affected by inadequate health and social care are too vulnerable to launch the protests that have addressed other forms of discrimination.

Services were irregular cross authorities unless you were prepared to pay. They were increasingly difficult to obtain for any but the most severely disabled. Why has sixty years of criticism produce so little change?

However, at a time of financial crisis, funding diminished and little changed. In the 1980s, the government cut spending. Meanwhile, preference for private over public s学习万博manbetxervices made management even more difficult. Simultaneously, the number of sick, older people grew. Governments emphasized the need to improve services. They did so th其实parametersough, while doing little to stop the erosion of available aid.

Current services originated in two key measures. They are the National Health Service and the 1948 National Assistance Act. This required local government to provide residential accommodation for older people and supervise care homes run by independent organizations. They also provide home and community services including meals, day centers and home helpers and other subsidized services. The National Health Service was free and wholly publicly provided. It delivered the best health care for all. No such vision guided residential and community care though. The care was substantially provided by voluntary services which work together with local authorities as they long had with eligibility based on income. Today, life expectancy has risen from 66 fo你知道万博manbetxr a male at birth in 1948 to around 80 now. In addition, there is better overall health and improved medical knowledge in care. This means an unprecedented number of people are surviving longer in conditions requiring ex-birth support. Families provide at least as much of care as they ever did. Even so, they can rarely without subsidized support address serious personal needs. Care for older people faced persistent criticism as these trends became apparent. From the early nineteen sixties, local authorities were required to plan health and welfare services. T你看thehe aim was to enable older people to remain in their own homes for as long as possible. But this increased concern about the lack of coordination between free health and paid for social care. Through the nineteen seventies, a number of measures sought to improve matters.

Today’s crisis in care for older people in England has two main causes. First, people are living longer with a lot more complex needs. Second, they rely on a system that has lo相比看theng been marked by a poor relation between national health and social care services.

Question 21: What has a Japanese research team tried to do?

Question 20: What is Tim Councilman trying to do in Sacramento?

Question 19:万博manbetx What has the speaker previously talked about?

The gas can be stored under pressure in a tank to recover the energy. The gas is bent back over the calcium oxide. In theory, says Valentine, this can create a high enough temperature to generate superheated steam.

For examstickple, a team at Tohoku University in japan has studied materials that can store large amounts of heat. When he did, these materials turned from a solid into a liquid, absorbing energy as they ofchange phase. The liquid is maintained above its melting point until steam is required, at which point the liquid is allowed to turn back into a solid, releasing its stored energy. Another team at Nagoya University in japan has tested calcium compound as an energy storage material, heating this chemical compound drives off carbon dioxide gas, leaving calcium rememberoxide.

This would generate steam that could be used to fill tanks on a small steam train without the use of fire. Supplying power to trains in this way would offer万博manbetx the shortest distance from well to wheels, he says, with the least amount of energy lost, according to harry valentine, a Canadian engineer who was researching modern steam technology, a special tank measuring two by ten meters could store over seven hundred and fifty kilowatt hours of energy as high pressure steam enough to pull a two car train for an hour or so. Energy to drive a steam locomotive can be stored in other materials besides water.

And his home city of Sacramento, California should see the technologies first test as part of the upgrading of its rail yard. Councilman, who is an inventor and self-proclaimed steam visionary, is campaigning for a new steam train that runs without any fire and could run on an existing ten kilometer line, drawing tourists and perhaps offering city commuters看着万博manbetx我不知道of a green alternative to their cars. Councilman wants to build an array of solar magnifying mirrors at one end of the line to collect and focus hremembereat onto water filled tubes.

We’ve talked recently about the importance of sustainable energy. We've also talked about the different theories on how that can be done. So far, our discussions have all been theoretical. Now I have a practical question for you all. Can you run a one hundred and forty thousand kilogram train on just the steam generated by solar power? Well, one engineer, Tim councilman believes it's possible.

Question 18: What is the fundamental limit我不知道parametersation of machine learning?

Question 17: What do we learn about Kaggle company’s winning programs?

Question 16: What did the researchers at Oxford University conclude?

But there are things we can do that machines can't do. Where machines have made very little progress is in tackling novel situations. Machines can't ha相比看parametersndle things they haven't seen many times before. The fundamental limitations of machine learning is that it needs to learn from large volumes of past data. But humans don't. We have the ability to connect seemingly different threads to solve problems we've never seen before.

Now, given the right data, machines are going to outperform humans at tasks like this. A teacher might read 10,000 essays over a 40-year career. A machine can read millions of essays within minutes. We have no chance of competing againstBut machines on frequent, high-volume tasks.

Machine learning started making its way into industry in the early 90’s. It started with relatively simple tasks. It started with things like assessing credit risk from loan applications, sorting the mail by reading handwritten zip codes. Over the past few years, we have made dramatic breakthroughs. Machine learning is now capable of far, far more complex tasks. In 2012, Kaggle challenged its community to build a program that could grade high-school essays. The winning programs were able to match the grades given by human teachers.

In 2013, researchers at Oxford University did a study on the future of work. They concluded that almost one in every two jobs have a high risk of being automated by machines. Machine learning is th相比看万博manbetxe technology that's responsible for most of this disruption. It's the most powerful branch of artificial intelligence. It allows machines to learn from data and copy some of the things that humans can do. My company, Kaggle, operates on the cutting 学会万博manbetxedge of machine learning. We bring together hundreds of thousands of experts to solve important problems for industry and academia. This gives us a unique perspective on what machines can do, what they can't do and what jobs they migh万博manbetxt automate or threaten.

Here is my baby niece Sarah. Her Mon is a doctor and her dad is a lawyer. By the time Sarah goes to college, the jobs her parents do are going to look dramatically different.

15. What do the researchers say concerning people’s feelings about will power?

14. What do we learn about European participants as compared with their American counterparts?

13. What is the finding of the new study?

12. What is often necessary for carrying through a task?

A good dose of will power is often necessary to see any task through, whether it’s sticking to a spending plan or finishing a great novel. And if you want to你看stick increase that will power, a new study suggests, you just simply have to believe you have it. According to the study, what matters most is what we think about our will power. If we believe it’s a finite resource, we act that way. We feel exhausted any breaks between demanding mental tasks. However, people who view their will power as a limitless resource get energized instead. The researchers used a psychological assessment tool to test the validity of the study. They asked one thousand one hundred Americans and one thousand six hundred Europeans to grade different statements such as “after a challenging mental activity, my energy is depleted and I must rest to get it refueled again” or “I can focus on a mental tamanbetxsk for long periods without feeling tired.” Although there was little difference between men and women over all, Americans were more likely to admit to needing breaksticks after completing mentally challenging tasks. European participants, on the other hand, claimed they were able to keep going. Based on the findings, the researchers suggest that the key to boosting your will power is to believe that you have an abundant supply of it. Your feelings about your will power affect the way you behave. But these feelings are changeable, they said. Changing your beliefs about the nature of your self-control can have positive effects on character development. This leads to healthier behaviors and perceptions of other people.

Passage 2

Q11: rememberWhat may occur in 20 years according to scientists' recent observations?

Q10: What does the passage say about the temperature surge in the Arctic?

Q9: What did climate scientists describe as stunning?

Previously, climate forecasts predicted that Arctic summer ice would disappear entirel万博manbetxy by around 2060. But based on what scientists are seeing now, the Arctic may be facing summers without ice within 20 years.

Overall, Earth is warming at a rapid pace — 2014 through 2017 rank as the hottest years on record —a对于Butnd the Arctic is warming twice as fast as anyplace else on Earth. This raises unique challenges for Arctic wildlife and indigenous people who depend on Arctic ecosystems to survive.

This is troubling as climbing Arctic temperatures combined with rapid sea-ice loss are creating a new type of climateto feedback loop which could accelerate Arctic warming. Indeed, sea-ice cover in the Arctic is melting faster than expected. Without those masses of cooling sea ice, warm air br学会toought to the Arctic can penetrate further inland than it ever did before. The air can stay warmer, and longer too. This drives additional melting.

Weather conditions that drive this bizarre temp万博manbetxerature surge have visited the Arctic before. They typically appear about once in a decade. However, the last such increasing temperature took place two years ago.

On February 20th, the temperature in Greenland climbed above freezing or zero degree Celsius and it stayed there for over 24 hours. Then, on February 24th, the temperature on Greenland northern tip reached 6 degree Celsius. Climate scientists described the phenomenon as stunning.

During the Arctic winter from October to March, the average temperature in the frozen north typically hovers around minus 20 degrees Celsius. But this year, the Arctic is experiencing much higher temperatures.

Passage 1:

Q8: What does the professor say the man has to d万博manbetxo?

Q7: What is the man really more interested in?

Q6: What does the professor think of the man's topic?

Q5: What is the man's problem?

Questions 5-8 are based on the conversation you have just heard.

W: If there is anything else you need, please come see me in my office anytime.

M: Great! Thanks for taking the time to answer my questions, professor. I'll let you get back to class now.

W: Exactly. I suggest you go to the library and get a copy of his biography. Start from there. But remember to stick to the parameters of the assignment. This paper is a large part of your accumulative grade, so make sure t学会万博o follow the instructions. If you take a look at his biography, you can get a good idea of how his life experiences manifest themselves in his theories of beauty, specifically, the way he looked towards nature as the origin of what we find beautiful.

M: Oh yeah. He's the philosopher who wrote about where our ideas of beauty come from.

W: I'm afraid you have to adhere to the assigned topic. Still, if you are interested in nature, then that certainly can be worked into your dissertation. We've talked about Hume before in class right?

M: Exactly. That's what I wanted to ask you about. I was hoping it would be possible for me to change topics. I'm really more interested in nature than beauty.

W: Yeah, that's much too large a topic. You really need to narrow it down in order to make it more accessible, otherwise you will be writing a book.

M: The general topic I chose is aesthetics. But that's as far as I've got. I don't really know where to go from there.

W: Sure. I have quite a few students though. So can you remind me what your topicthe is?

M: Hi professor! I was hoping I could have a moment of your time, if you are not too busy. I'm having some problems getting started on my dissertation and I was hoping you could give me some advice on how to begin.

Conversation Two

Q4: How does the book cultivate readers’ interest in psychics?

Q3: How does the author bring her book to life?

Q2: What can we find in the book the man recommended?

Q1: What does the woman say about the book the man recommended?

Questions 1-4 are based on the conversation you have just heard.

W: Yes, I must say this equation-free book is an ideal read for scientists of all stripes, anyone teaching science and even people who dislike psychics.

M: Yeah, I like how she cultivates s万博manbetxcientific engagement by providing the host of Do It Yourself experiments that bring the same foundation of principles of classical physics that govern everything from the solar system to your kitchen table. From using complex laws of psychics to test whether a spinning egg is cooked, to measuring atmosphere pressure by lifting a piece of cardboard. Her hands-on examples make her book a truly interactive read.

W: I like how the book is clearly written with each chapter brought to life by pieces of fascinating knowltoedge. For example in one chapter, she exposes a myth that I’ve heard taught by university physics professors. I’ve often heard that medieval glass windows are thicker at the bottom because glass flows like fluid. This, she shows, is not true. The distortion is actually thanks to a peculiarity of the glassmakers’ process.

M: And it's refreshing to see a strong curious clever woman adding her voice to the scientific discourse and a field that has been traditionally dominated by men. I think she has to be commended for making an effort to include anecdotes about little known female scientists. You know, thtoey were often victims of a generation firmly convinced that the women’s place was in the home.

W: Oh I read that book. It was great. The writer is a warm and competent guide to the mysteries of physics. I think it promises enrichment for any reader from those who know little about science to the career physicist.

M: Hey, I just read a great book about physics. I think you'd like it. It is called The Physics of the World. It is written by a scientist named Sylvia Mundus.
