According to a new study from Cornell University, about one-fifth of the global population, of 2 billion people worldwide, will be forced to resettle or go deeper inland by 2100 due to the continuous rise in sea level.
The study, published in the journal Land Use Policy, showed that the growing global population could make the matter worse. The researchers expected that there are about 1.4 billon “climate change refugees(难民)” in the world by 2060 and by 2100 the number of the displaced people due to the rising sea level could reach up to two billion.
“We’re going to have more people on less land and sooner than we think,” said lead author Charles Geisler, professor at Cornell. “The future rise in global average sea level probably won’t be gradual. Yet few policy makers are observing the significant barriers that coastal climate refugees, like other refugees, will run into when they move to higher ground.”
For the study, the researchers reviewed(回顾) potential problems that climate change refugees may face if they go deeper inland. The researchers identified these land difficulties with relocation using three organizing groups. Including depletion(损耗) zones, win-lose zones and no-trespass(不得擅自进入) zones. By doing so, the researchers were able to provide primary estimates of their toll(损失) on inland resettlement space. The researchers found that some inland regions were unlikely to support new waves of climate change refugees due to the remains of war, road developments and rare natural resources.
Apart from the rising sea level, increasing storm weather and the booming global population are also having a huge influence on the number of climate change refugees. Storm can push seawater further inland. The increasing global population requires more land even as the ocean swallows up rich costal zones and river deltas(三角洲). These force people to search for new places to move to higher ground.
1.What would happen if the sea level were to rise?
A.2 billion people would be “refugees” by 2060.
B.50% of the population would lose their homes.
C.Inland regions would become more crowded.
D.Coastal regions would be polluted seriously.
2.What can be inferred from Charles Geisler’s words?
A.The sea level will go up in a little-by-little way.
B.Moving to higher land isn’t the key solution.
C.Land and population vary according to climate change.
D.Policy makers should think more for climate change refugees.
3.Why do climate change refugees fail to move to some inland regions?
A.Because they can’t live a common life there.
B.Because they can’t adapt to the climate there.
C.Because they may consume more than expected.
D.Because they will destroy the natural resources.
4.What does the author stress in the last paragraph?
A.Global warming is a double-edged sword.
B.In the future climate will become worse.
C.The earth will see more climate change refugees.
D.Sea will bring humans more disadvantages.

A new study from Harvard University revealed that the message parents mean to send to children about the value of sympathy(同情心） is being mistaken by the message they actually send. In fact they value achievement and happiness above all else.
The Making Caring Common Project at Harvard’s Graduate School of Education surveyed 10,000 middle and high school students about which is more important to them—achievement, happiness, or caring about others. Almost 80 percent of students placed achievement or happiness over caring about others. Only 20 percent of students considered caring about others as their top aim.
In the study “The Children We Mean to Raise: The Real Message Adults Are Sending about Values”, the authors refer to a reality gap, an incongruity (不一致) between what adults tell children they should value and the message we grown-ups actually send through our behavior.
Simply talking about sympathy is not enough. While 96 percent of parents say they want to raise caring children, and cite the development of moral character as “very important, if not essential”, 80 percent of the youths surveyed reported that their parents “are more concerned about achievement and happiness than caring about others”. Approximately the same percentage of the students reported that their teachers put their achievement over caring.
As the report shows, simply talking about sympathy is not enough. Children are sensitive creatures, fully capable of telling the true meanings in the blank spaces between well-organised words. If parents really want to let their kids know that they value care and sympathy, the authors suggest, they must make a real effort to help their children learn to care about other people—even when it’s hard, even when it does not make them happy, and yes, even when it is at odds with their personal success.
1.The first paragraph suggests that parents _____.
A. value achievement less
B. fail to make students realize the importance of sympathy
C. don’t intend to value success
D. regard achievement and happiness as the same
2.What can be concluded from the study?
A. 20% of the students are not ambitious.
B. Kids care more about achievement.
C. About 80% of the students are not caring.
D. A majority of the kids are kind students.
3.What may be the cause for the reality gap?
A. Children’s failure to understand parents’ well-organised words.
B. The generation gap between parents and children.
C. Children’s desire for getting individual achievement.
D. Parents’ lack of a real effort to guide children.

According to new research from the University of Cambridge in England, sheep are able to recognize human faces from photographs. The farm animals, who are social and have large brains, were previously known to be able to recognize one another, as well as familiar humans. However, their ability to recognize human faces from photos alone is novel.
The recent study shows the woolly creatures could be trained to recognize still images of human faces, including those of former President Barack Obama and actress Emma Watson.
Initially, the sheep were trained to approach certain images by being given food rewards. Later, they were able to recognize the images for which they had been rewarded. The sheep could even recognize images of faces shown at an angle, though their ability to do so declined by about 15 percent—the same rate at which a humans ability to perform the same task declines.
“Anyone who has spent time working with sheep will know that they are intelligent, individual animals who are able to recognize their handlers,” said Professor Jenny Morton, who led the Cambridge study. “We’ve shown with our study that sheep have advanced face-recognition abilities, comparable with those of humans and monkeys.”
Recognizing faces is one of the most important social skills for human beings, and some disorders of the brain, including Huntington’s disease, affect this ability. “Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand disorders of the brain, such as Huntington’s disease, which develop over a long time and affect cognitive abilities. Our study gives us another way to monitor how these abilities change,” Morton said.
1.According to the new research, what’s unusual about sheep?
A.They have large brains.
B.They can recognize their owners.
C.They can tell animals from humans.
D.They can recognize human faces from photographs.
2.How did the researchers train the sheep?
A.By giving food rewards.
B.By showing photos of famous people.
C.By guiding them to follow their handlers.
D.By showing photos of humans and monkeys by turns.
3.What can be inferred from the passage?
A.Sheep have a higher face-recognition ability than monkeys.
B.Sheep recognize faces same well when shown photos at any angle.
C.The new discovery is beneficial to the study of cognitive ability changes.
D.The sheep’s face-recognition ability may prevent some disorders of the brain.
4.What’s the best title of the passage?
A.A Wonderful Scientist
B.The Life of Sheep
C.The Sheep’s Recognition of Each Other
D.A New Discovery about Sheep

Many kids don't drink enough water daily, according to a new study. The study's lead author, Erica Kenney, at first planned to look into the amount of sugary drinks kids were drinking in schools. However, during her research she found that many kids were simply not drinking enough water.
Kenney and her team examined data from a group of 4,000 children, aged 6 to19, between the years of 2009 and 2012. The data was taken from the National Health and Nutrition Survey,a study on the health of children in the United States conducted each year by the Center for Disease Control and Prevention..
While looking through the survey results, she noticed that more than half of the kids who took part in the study were dehydrated (脱水的). Of' that group, boys were 76% more likely than girls not to have enough water in their system. Nearly one quarter of the kids in the survey reported drinking no plain water at all.
“These findings highlight(突出) a possible health issue that wasn't given a lot of attention in the past," Kenney said in a statement. “Even though for most of these kids this is not an immediate and great health threat, this is an issue that could really be reducing quality of life and well-being for many children and youth."
The United States-National Agriculture Library says average kids need between 10 to 14 cups of water every day. This water can come from a mix of drinks and foods that contain high amounts of water, such as celery, melons or tomatoes. It is also recommended that fluids（液体）come from water instead of sugary drinks that are high in calories and can lead to weight problems.
1.What was Erica Kenney's purpose in doing the study?
A. To study if kids drink enough water daily :
B. To prove that sugary drinks are harmful to kids
C. To show what kind of sugary drinks kids love.
D. To find out how many sugary drinks kids drink at school.
2.According to the findings of Erica Kenney's study, we know that ________.
A. school kids cannot find drinkable water easily
B. boys are more likely to get dehydrated than girls
C. sugary drinks are very popular with school kids
D. most kids know the importance of drinking plain water .
3.From the last paragraph we learn that kids________.
A. should drink plain water to lose weight
B. can try to take in water from sugary drinks .
C. can eat celery, melons and tomatoes for water .
D. should drink no more than 10 cups of water every day
4.The text mainly tells us that many kids_____________
A. don ' t like drinking water
B. prefer sugary drinks to water
C. are at risk of health problems
D. don ' t drink enough water daily

According to a new US study, couples who expect their children to look after them in old age should hope they have daughters because daughters are twice as attentive as sons overall.
The research by Angelina Grigoryeva, from Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.
Her analysis of the family networks of 26,000 old Americans concluded that gender(性别) is one of the most important things that decide whether or not people will actively care for their elderly parents.
In a paper presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men likely provide less care. Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over 50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.
"Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother."
"This suggests that sons pass on parent caregiving responsibilities to their sisters."
In the UK, the 2011 Census showed that there are now around 6.5 million people with caring responsibilities, a figure which has risen by a tenth in a decade.
But many are doing so at the risk of their health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a fulltime job are three times more likely to be struggling with ill health than their working counterparts who are not carers.
1.According to the passage, what’s the most important factor to predict if people will actively care for the elderly?
A.Education. B.Gender. C.Career. D.Income.
2.The US study finds that_____.
A.having a sister makes men less likely to look after their parents
B.sons are twice as likely as daughters to care for parents in old age
C.sons are unwilling to leave caregiving responsibilities to their sisters
D.sons and daughters seem to give equal care to their parents
3.What does the author stress in the last paragraph?
A.People should give up their job to care for the elderly.
B.Many care providers work longer hours than others.
C.Many care providers have potential health problems.
D.People shouldn’t pass on caring responsibilities to others.
4.The author develops the text by _______.
A.explaining social networks of careers B.describing people' s experiences

Painkillers (止痛药) are turning out to be a real pain: according to a new study in the British Medical Journal. Taking them for just a week can increase your risk of heart attack by 50%. The research suggested that the risk related to the use of certain drugs was greatest with higher doses (服用量) and during the first month of use. The potential risk may increase by 75% for medicines like ibuprofen (布洛芬) and naproxen, and more than 100% for rofecoxib.
It all sounds bad but, your risk is very low, — say, one in a million — a 100% increase means you still only have a two in a million chance. Of course, all painkilling medication that works can have side effects — nothing is safe and effective. Paracetamol (扑热息痛) has very few unless taken too much, in which case it can cause serious liver danger, but it isn’t very effective. Drugs like opiates are strong painkillers but easy to be addicted and often have other bad effects. Maybe you find that you are in a dilemma now. But don’t despair; you can refer to a pain clinic for some professional guidance. For ongoing pain, music and exercise may be the best choices to help you reduce the feeling of it.
Scientist at Harvard have recently done a quite horrible study on mice. They made the mice experience extremes of hot and cold, applied pressure to their back legs and injected the capsaicin (辣椒素) into their feet. And then they timed how long it took them to respond to the pain. Lack of sleep increased the discomfort, while stimulants (兴奋剂) such as caffeine made them less responsive to pain. This has been widely reported that a good night’s sleep and a cup of coffee in the morning may help reduce pain.
But anyway, don’t throw the pills away because the study also shows taking small doses of drugs, such as for short periods of time can be effective and safe as long as your heart is in good condition.
1.Which of the following painkillers has fewest side-effects?
A.Ibuprofen. B.Naproxen.
C.Rofecoxib. D.Paracetamol.
2.What does the underlined word “despair” in Paragraph 2 refer to?
A.Take it seriously. B.Take any risks.
C.Lose hope. D.Feel doubtful.
3.The example of mice is used to show that ____
A.mice can stand extreme pressure
B.good sleep and coffee may decrease pain
C.legs and feet are more sensitive to pain
D.capsaicin and stimulants can help reduce pain
4.What is the text mainly about?
A.How to stop taking painkillers. B.A new way of reducing pain.
C.The risk of taking painkillers. D.How to avoid painkillers’ side effects.
