Britain is set to face an increase in cold winters, with up to one-in-seven hitting the UK with longer periods of time when temperatures are below freezing, a study has suggested.The prediction was based on research that found out how low solar activity affected winter weather patterns.
However, the researchers were eager to stress that their findings did not suggest that the region was about to fall suddenly into a "little ice age".The findings appear in the journal Environmental Research Letters."We could get to the point where one-in-seven winters are very cold, as we had at the start of last winter and all through the winter before last," said co-author Mike Lockwood, professor of space environment physics at the University of Reading.
Using the Central England Temperature (CET) record, the world's longest instrumental data series that dates back to 1659, the team said that in general temperatures during recent winters had been obviously lower than the longer-term temperatures."The mean CET for December, January and February for the recent relatively cold winters of 2008 ~ 2009 and 2009~2010 were 3.50℃ and 2.53℃ respectively," they wrote. "However, the mean value for the previous 20 winters had been 5.04℃.The series of lower winter temperatures in the UK during the last three years had raised questions about the probability of more similar, or even colder, winters occurring in the future."
Last year.Professor Lockwood and colleagues published a paper that found a link between fewer sunspots and atmospheric conditions that "blocked" warm westerly winds reaching Europe during winter months, opening the way for cold easterly winds from the Arctic and Russia to sweep across the region.Professor Lockwood, while acknowledging that there were a range of possible meteorological factors (气象因素) that could influence blocking events, said the latest study moved things forward by showing that there was "improvement in the predictive skill" when solar activity was taken into consideration.
1.We can know from the second paragraph that _____.
A.research shows that Britain will soon fall into an ice age
B.Mike Lockwood's research focuses on space environment physics
C.it was quite cold in Britain over the entire winter last year
D.so far one-in-seven winters have been very cold in Britain
2.The.underlined word "mean" in Paragraph 3 is closest in meaning to "_____".
A.average B.stable C.ungenerous D.changeable
3.What can we infer from the last paragraph?
A.It was sunspots that blocked warm westerly winds reaching Europe.
B.Meteorological factors hardly have any influence on blocking events.
C.The latest study done by Professor Lockwood was of little practical value.
D.Considering solar activity or not affects the accuracy of weather forecasting.
4.What's the best title of the passage?
A.Another big danger approaching the UK
B.Research finds out solar activity is to blame for the cold
C.UK faces more cold winters due to weaker solar activity

Getting up in a cold winter morning is even a difficult thing to do and doing some exercise outdoors seems a tough task. 1. . People who run outdoors simply need to dress in the appropriate clothing.
Running in the cold actually helps burn more calories compared to the same activity done indoors. Cold weather basically requires the body to work harder to achieve perfect temperature for efficient functioning.
Cold winter weather is a common excuse for people to get lazy and stay indoors. Some people also eat a whole lot when it’s cold outside. 2.. With these, the body’s metabolism(新陈代谢) will also slow down and eventually result in weight gain. When running is done, possible weight gain may be prevented.
3. When the temperatures are freezing and low, the body’s metabolism will also slow down and the only way to promote blood circulation is to do some exercise like running.
Having depression or a sad mood is common during the winter months. 4. Doing some running will also help to lift spirits up and make people happier.
Running activities basically help the body become healthy and strong regardless of indoors or outdoors. The additional thing is that the body needs extra work to knock back the freezing temperatures. 5..
A.Good blood circulation promotes metabolism
B.Running outdoors is also good exercise for the heart
C.With this, people will not only become healthier but also happier
D.The changes lead to people feeling down during the cold winter months
E.However, running outdoors in winter may actually provide various benefits
F.Other people meanwhile tend to watch TV all day or sleep for longer periods
G.These feelings are regarded as a common phenomenon with those living in the north

Britain faces social problems as lots of people are set to lose their jobs in technological revolution, Bank of England’s chief economist warned.
Andy Haldane said the so-called Fourth Industrial Revolution will make the machine replace humans to do thinking things. The dark side of the change could be a much bigger breakdown of employment than in Victorian times, with professions such as accountancy (会计) among those at risk.
A report by the accountancy firm PwC last month warned that more than 7 million jobs in Britain had been lost over the next 20 years as technological change sweeps though workplaces.
The majority of these are in jobs in the retail, transport and manufacturing industries. However, other traditional professional sectors could also be at serious risk.
Economists treat the arrival of increasingly intelligent computers and robots as the fourth industrial revolution. The first was the shift from agricultural to urban societies, the second saw the widespread use of electricity and steel, and the third was the digital revolution when computers, the Internet and mobile phones were developed.
Mr Haldane said the hollowing-out (空洞化) experienced in the past years could be on a greater scale in the future so it is important to learn the lessons of history and ensure that people are given training to take advantage of new opportunities.
“Jobs were effectively taken by machines of various types, there was a hollowing-out of the jobs market, which left many people for a long period out of work and struggling to make a living,” Haldane added, “That heightened social and financial tensions, and led to a rise in inequality. This is the dark side of technological revolution.”
“That hollowing-out is going to be potentially on a much greater scale in the future, when we have machines thinking and doing the cognitive and technical skills of humans.” Mr Haldane said professions like accountancy could be among those hardest hit by the rise of AI. But he suggested economists could escape.
1.What is the dark side mentioned in the text?
A. The hollowing-out has become a major social problem.
B. Less and less people have the desire to learn accountancy
C. Intelligent computers and robots decrease good workers.
D. The technological revolution causes people to lose jobs.
2.Why are economists the lucky dog in the new technological revolution?
A. The study about economy is at a low level.
B. Economists work on a traditional professional job.
C. There is no machine that can work as an economist.
D. Economists have the chance to avoid technological revolution.
3.What should be done to deal with the serious situation?
A. To call for people to devote more to studying history.
B. To teach people to grasp the chances technological revolution brings about.
C. To warn people not to work on transport and manufacturing industries.
D. To ask workers to develop and think as the intelligent computers and robots do.
4.What attitude did Haldane have towards the future employment?
A. Positive. B. Aggressive.
C. Critical. D. Worried.

Your money or your time?
A friend once invited me to spend a cold winter’s day picking up rubbish in a park. It was a community-service event organized by a charitable organization(慈善组织) she was involved with. I immediately told her I was not interested.
“It just makes no sense,” I explained. “Why would I spend three hours of my time picking up rubbish?” I argued that if the goal was neighborhood beautification, then I would rather donate three-hours’ worth of my labor income. The organization could then hire several people in need of a job. The rubbish gets picked up, we provide jobs, and I do not have to spend three hours in the cold. “Where can I make a donation?”
My friend sighed, said something in a low voice about it seeming like a good way to meet men, and then shuffled off to ask someone else.
When we feel inspired to do good, many of us choose to give time instead of money. Given how precious our time is– limited by demands of work, family and friends–setting some of it aside to clean parks or deliver meals seems like a valuable donation. But is this the most efficient way to give?
The economist in me is inclined to say no. As I explained to my friend, what my time is worth may be far more valuable to most charities than my actual labor. The money could go towards hiring people with limited employment opportunities, or to help cover more pressing needs facing the charity, such as rent or staff salaries. My hours of labor, on the other hand, serve the charity in only one way, and can only be provided by me.
Volunteer labor becomes more valuable if it involves a special skill. For example, if a talented doctor donates a few hours of his time to a free clinic, this may serve the charity better than a $1,000 donation. Unfortunately, I can think of few local charities that would benefit from the unique skills of an economist.
I recently explained this to a professional who regularly donates his time to a local soup kitchen. But he argued that “just throwing money at a cause” is potentially irresponsible and enables disengagement. Donating time may be a greater personal sacrifice, but it also gives him a stronger connection with the cause. He has created a bond not only with the other volunteers, but also with the people he feeds, and the result is an enriching sense of community. He also believes, as a member of the same minority group of many of the people he serves, that he provides them with a positive role model. He recognizes the value in the social interaction volunteering provides.
Of course charities benefit from both kinds of donations. They need some people to just hand over cash, but they also develop successfully by being an important part of the community. Whether it is better to give money or time depends on your goals as a donor. If the objective is simply to provide food for the hungry or to clean a park, then money is more valuable. However, if you hope to also engage with your community–not only with your peers, but also with less fortunate people whom you might not otherwise meet –no amount of money can make up for your time spent.

A. describe a scene B. lead in a topic

2.The author believes there are some efficient ways to donate EXCEPT.

A. is willing to serve the charity

C. tends to reject giving time instead of money
D. is longing to share his efficient way to give with his friend
4. In the professional’s opinion (Paragraph 7), donating time is .
A. one-sided B. debatable
C. meaningless D. reasonable
5.Which of the following does the author finally agree with?
A. It is donors’ participation that really matters.

高三英语单项填空中等难度题查看答案及解析
Is it okay to keep exercising when you have a cold? What about the flu? With winter viruses going around, it’s important to know how to alter your training if you do catch a germ or two.
“The guidelines are pretty easy,” says Dr Lorenzo Masci from the Alphington Sports Medicine Clinic. “Anything above the neck --- so if you’ve got a cold for example, a runny nose or a sore throat --- then you should probably cut down your exercise by half and do 50 percent of what you normally do.”
“If you’ve got anything below the neck, like muscle pain, joint pain or fever, you shouldn’t really exercise at all until those general symptoms settle down,” Lorenzo says. He points out that a cough would also fall into this more serious category. “For example, if anyone comes in with a fever and a runny nose, I’d tell them to stop exercising until the fever and the muscle ache settles. Then they can start their training again at 50 percent once all those symptoms settle, even if they’ve got a bit of a runny nose or a sore throat.”
“The reason we tell people to stop exercising is because if you exercise when you’re unwell it can make the illness worse and prolong it.” There is a second reason Lorenzo advises his patients to stop exercising when they have “below the neck” symptoms. In the event you have an illness which affects your heart, exercise can sometimes actually lead to death.
Lorenzo advises to take zinc (锌) and vitamin C as a way of preventing colds. But he admits that this is controversial --- some studies have shown that these supplements can improve immune function while other studies have cast doubt on the issue. The good news is that if you exercise regularly, you’re likely to improve your immune function. “If you exercise too much, it can predispose (使倾向于) you to coughs and sniffles,” he points out. This is often the case for excellent athletes who train every day, such as triathletes (铁人三项运动员). “But what we do know is that if you exercise at a moderate level, your immune system improves such that you’re probably at a lower risk of developing coughs and colds.”
1.How many guidelines does Dr Lorenzo mainly suggest on doing exercises when people catch a cold?
A.One. B.Two. C.Three. D.Four.
2.How should people do exercises with a fever or a cough?
A.They should probably reduce their training time by 50%.
B.They should stop exercising until they recover.
C.They should start exercising at 50% after their runny nose settles.
D.They should do half of what they normally do.
3.What is the worst result if people don’t stop exercising when they are unwell?
A.Worsening the illness.
B.Prolonging the illness.
C.Affecting the heart.
D.Bringing about threat to life.
4.What can be proved from the last paragraph?
A.Zinc and Vitamin C can help to prevent colds.
B.The more exercises we do, the stronger our immune function will be.
C.Doing exercises regularly can help us prevent colds.
D.Excellent athletes seldom get coughs or sniffles.
5.What is this passage mainly about?
A.Relationship between exercises and flu.
B.How to do exercises.
C.How to cope with flu.
D.When to do exercises.
