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.

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.
Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.
Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12hour schedule, one of which joined the winter group, and one of which joined the summer group.
After 28 days, it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winterborn mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.
The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.
“We know that the biological clock regulates mood in humans,”said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”
1.How many groups of mice are there finally in all in the experiment?
A. Four. B. Five. C. Six. D. Seven.
2.What's the main idea of the text?
A. The biological clock regulates mood in humans.
B. People born in winter are at higher risk for physical health disorders.
C. Being born in winter has a negative effect on people's mental health.
D. The length of light will influence the behavior of the mice.
3.The underlined word “split”(Paragraph 3) can be replaced by ________.
A. ended B. torn C. hit D. divided
4.Who is the appropriate reader of the passage?
A. A jobhunter. B. A student in the university.
C. A newlymarried couple. D. An experienced dentist.

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.
