Divorce is bad for environment
US researchers raised a new theory on Monday: divorce is bad for the environment.
The global trend toward higher divorce rates has created more households with fewer People，
scientists at Michigan State University reported in the Proceedings of the National Academy of
Sciences．
More households means more houses，fuel and water are Heeded for them，the researchers wrote．“Globally，the number of households is increasing much faster than the number ofpeople，”said co-author “Jack” Liu in a telephone interview. “Even in regions with declining populationn, we see substantial increase in the number of households. Divorce is the main reason for reducingthe number of people in a household,” he said.
The average divorced person’s household is about 40 to 50 percent smaller than the average married person’s household, Liu said. But whether there are three or six people in a house ,the amount of fuel needed to heat them is about the same. In the United States, divorced households used 74 billion kilowatt—hours of electricity and 2.850 trillion liters of water in 2005, half of which could have been saved if households had stayed the same size as when they were married.
In the United States and 11 other countries between 1998 and 2002, if divorced households had combined to have the same average household size as married households, there could have been 7.4 million fewer households.
The number of divorced households in those countries ranged from 40,000 in Costa Rica to
almost 16 million in the United States around 2000. The number of rooms per person in divorced households was 33 percent to 95 percent greater than in married households.
“If you really want to get divorced, maybe you can remarry with somebody else, or live together with somebody else you like”, Liu said.
1. In America when the number of households is_________, the number of people in a house is__________.
A. increasing, decreasing B. decreasing, increasing
C. increasing, increasing D. decreasing, decreasing
2. What does the word “substantial” in the third paragraph mean?
A. Great B. Little C. Sudden D. Timely
3. How much electricity would have been saved without so many people getting divorced in America in 2005?
A. 7.4 million kilowatt-hours B. 16 million kilowatt-hours
C. 37 billion kilowatt-hours D. about 30 billion kilowatt-hours
4. The last paragraph is the writer’s_________for people.
A. advice B. encouragement C. demand D. order

Friendly doctors are“bad for their patients’health”，researchers have warned as a new study revealed two thirds of young doctors struggle to be truthful with patients they like．
Blurring(使…模糊)the lines between social and professional relationships can affect the level of care offered and prevent patients from being honest about important side effects．
“Doctors should avoid adding patients as friends on Facebook，they should not hug or allow patients to call them by their first names”．regulators have warned．“Those who break the boundaries will face some punishment．”
It comes as a survey of 338 oncologists(肿瘤科医生)under the age of 40，found 59 per cent said they found it difficult to tell the truth to those patients they liked．Sixty per cent of respondents said if doctors felt too close to their patients，it could prevent them from making objective decisions about a person’s care．
Lesley Fallowfield，of Brighton and Sussex Medical Schoo1．said：“Oncology is a profession that can be enormously rewarding but is filled with many challenges．Young oncologists have to master dealing with anxious patients who are facing a life-threatening disease；conveying the true prognosis(预后)；discussing the complexity of modern treatments；and explaining the unavailability of some drugs，the side-effects of treatment，and likely treatment aims．”
But she said，“Those doctors who have entered the profession in the age of the ‘Internet world’are more likely to fall victim to blurring the professional boundaries with patients．
She said：“The difficulty，if you hug and kiss patients，if you allow them to call you by your first name，is that quickly the relationship can become confused as a social one rather than a professional one．Doctors become confused，‘I really like this person，how can I bear to tell them that they’re going to die?’They find it more difficult to be objective．”
1.Why are ffiendl3，doctors bad for their patients’health?
A．They don’t like to cheat patients．
B．They are not good at treating patients．
C．They find it not easier to be objective to the patients．
D．They seldom blur the relationship with patients.
2.What should doctors do according to the regulations?
A．Add patients as friends on Facebook．
B．Have close connection with patients in life．
C．Always be cold to patients．
D．Keep a proper distance to patients．
3.Which opinion will Lesley Fallowfield agree with?
A．Oncology is a rewarding profession without challenges．
B．The Internet makes it easier for young doctors to break the boundaries．
C．It’s not the duty of doctors to deal with patients’anxiety．
D．Becoming friends with patients will help them recover soon．
4.Young oncologists will face the following challenges except_____________．
A．dealing with a lot of life-threatening diseases
B．discussing difficulties of treatment with patients
C．explaining the reason for the lack of some medicine
D．informing patients of the possible results of the treatment

Butter is bad for you—so is margarine（人造黄油）．Coffee raises blood pressure, but may protect against cancer．Alcohol is okay, but only if it's wine．The confusing studies on what is safe to eat and drink are enough to make it impossible for anyone to understand what "good food" is．
Take the margarine-butter debate for example．Studies that linked fat—found mostly in animal products such as meat and butter—with cancer and heart disease sent millions rushing to buy margarine．But then another study found that people who ate a lot of margarine also had high levels of heart disease．For those who have a firm faith in science, this seems to be the end of the world．
But many doctors point out that their advice has never been conflicting．For years, and in various countries, they have recommended eating less fat．
People in western countries such as Britain and the United States get about 40 percent of their calories from fat．Doctors say this should be around 30 or even 25 percent,
"We must try to reduce total fat," said Dr．Robert Richardson of the University of Edinburgh, who has been studying the effects of fat on human health for years．
"We need to go to more such food as bread, in particular brown bread, and more fruit and vegetables．"
Fresh produce may not be so safe, either．Last month the British Government advised consumers to peel their pears before eating, while many Americans briefly avoided apples because of fears over an insect killing chemical．
But Dr．Arnold, a British scientist, said any risk of such poisoning would be outweighed by the costs of not eating plant foods．
"On balance, if you were to put both risks against each other, the advice has to be eating as much fruit and vegetable daily as possible," she said．
In general, doctors conclude, variety truly is the best policy．"The general advice is pretty much the same advice that doctors have been talking about for a long time—a varied diet, a mixture of foods and not too much of any one," Arnold said．
1.In which section of the magazine are you most likely to find this passage?
A．Arts and Culture B．Entertainment
C．Nature D．Health
2.The British Government advised consumers to peel their pears before eating because ________．
A．it found that there were insects on the pears
B．it wanted consumers to avoid insect, killing chemicals
C．the skin of pears was found to be bad for people's health
D．it was a bad habit not to peel them
3.The underlined word "outweigh" （Para. 8） means " __________．"
A．to be heavier than usual or allowed B．to be more dangerous than
C．to be greater in value or importance than D．to be considered less important than
4.What can we infer from the passage?
A．Many doctors say that their advice has never been conflicting．
B．Science provides answers to all our questions．
C．We should peel our pears before eating．
D．We should eat plant foods despite the risk of poisoning．

Sleep, considered a luxury by many, is essential for a person’s wellbeing. Researchers have found that insufficient sleep increases a person’s risk of developing severe medical conditions. such as obesity, diabetes, and cardiovascular diseases. Now, a new study by Boston’s Massachusetts Institute of Technology ( MIT) has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Grossman, who led the research. was not trying to find the link between sleep and grades when he handed out Fitbits to the 100 students in his introduction to Solid-State Chemistry class. Instead, the professor of Computational Materials Science hoped the popular wrist-worn device which. tracks a person’s activity 24/7, would show a connection between physical exercise and academic achievement.
However, the study, published in the journal “Science Learning” on October 1, 2019, discovered a surprising insight. Then was a straight-line relationship between the average amount of sleep a student got and his/her grade on the 11 quizzes, three midterms, and the final exam administered during the semester.
Even more interesting, it was also not sufficient for students to just head to bed early the night before a test. Instead, it’s the sleep you get during the days when learning is happening that matters most.
The time students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher - performing student. “When you go to bed matters. Grossman says. If you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn’t everything.”
1.What is the new finding about sleep?
A.It's essential for a person’s health. B.Sleeping less may cause obesity.
C.Sleeping too much is dangerous. D.Ample sleep leads to better grades.
2.What does the underlined word “Fitbits” in paragraph 2 refer to?
A.Wearable devices. B.Questionnaires.
C.Fitness equipment. D.Smartphones.
3.Which of the following best describes the final result the new study?
A.Doubtful. B.Predictable.
C.Disappointing. D.Unexpected.
4.What will benefit students’ study according to Grossman?
A.Sleeping for 5 hours each day. B.Heading to bed at 3 a.m every day.
C.Getting enough sleep while learning. D.Going to bed early only before a test.

Sleep, considered a luxury by many, is essential for a person's wellbeing. Researchers have found that insufficient sleep and tiredness increase a person's risk of developing severe medical conditions, such as obesity (being very overweight), high blood sugar levels, and heart disease. Now, a new study has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smart watches to the 100 students in his chemistry class. Instead, the professor hoped the wrist-worm devices, which track a person's physical activity, would show a connection between exercise and academic achievement.
While Gross's data showed no relationship between these two factors, the study found something surprising. As the researchers were analyzing their data, they noticed that there was a straight-line relationship between the average amount of sleep a student got and their results in the course's 11 quizzes, three midterm tests, and the final exam.
Even more interesting, it was not sufficient for students to just head to bed early the night before a test. Instead, it's the sleep you get during the days when learning is happening that matters most.
The time students went to bed each night was similarly important. Those who went to bed in early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. "When you go to bed matters," Gross says, "If you go to bed at 10, or 12, or 1 at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn't everything."
Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students' grades. The overall course grades for students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who varied their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtimes.
Who knew getting A's just required some extra ZZZ's?
1.Based on his original objectives, which best describes Professor Gross's research findings?
A.Accidental. B.Complete. C.Convincing. D.Doubtful.
2.Who were the people taking part in the study?
A.Middle school chemistry students. B.Volunteers from different universities.
C.Professor Gross's own students. D.University student athletes.
3.How did Professor Gross's team measure academic performance?
A.Making the students wear a special watch.
B.Using students' university entrance test results.
C.Giving the students regular after class quizzes.
D.Using the students' normal test and quiz grades.
4.Based on the study's findings, who is likely to perform best academically.
A.A person who has a good night's sleep the night before an important test.
B.A person whose normal bedtime varies between 9 p.m. and 12 p.m.
C.A person who sleeps from 11 p.m. to 6 a.m. each day.
D.A person who sleeps for a total of 7 hours each night.

Anger is good for you, as long as you control it, according to new psychology research. A new study from Carnegie Mellon University shows anger may help people reduce the negative impacts of stress and help you become healthier.
“Here getting emotional is not bad for you if you look at the case of anger,” said Jennifer Lerner of Carnegie Mellon. “The more people display anger, the lower their stress responses.”
Lerner studied 92 UCLA students by asking them to count back from 6,200. They must say out loud every thirteenth number. Researchers disturbed them by asking them to count faster or ask them other questions. If they made any mistakes, they had to restart from the very beginning. Many students felt depressed about making so many mistakes or got angry.
Lerner used a hidden video camera and recorded all their facial expressions during the test. The researchers describe their reactions as fear, anger and disgust.
Other researchers recorded the students’ blood pressure, pulse and production of a high-stress hormone（荷尔蒙）called cortisol. People whose faces showed more fear during the experiment had higher blood pressure and higher levels of the hormone. Both can have lasting effects such as diabetes（糖尿病）, heart disease, depression and extra weight gain.
When people feel fear, negative impacts increase, but when they get angry, those negatives go down, according to the study.
“Having that sense of anger leads people to actually feel some power in what otherwise is a maddening（令人发狂的）situation,” Lerner said.
Lerner previously studied Americans’ emotional response to the 9/11 terrorist attacks two months after the incident. She found people who reacted with anger were more optimistic. These people are healthier compared with those who were frightened during the event. So in maddening situations, anger is not a bad thing to have. It’s a healthier response than fear.
1.What is the story mainly about?
| A．The findings of new psychology research. |
| B．What you can do with anger in certain cases. |
| C．Different effects produced by anger and fear. |
| D．Healthier responses in maddening situations. |
2.Which statement will Jennifer Lerner agree with?
| A．It’s better to be angry than to be frightened. |
| B．Different reactions reflect different outlooks on life. |
| C．Don’t control your anger and it makes you powerful. |
| D．Pessimistic people are generally healthier than optimistic people. |
3. What does the underlined word “both” refer to according to the passage?
| A．Fear and anger. | B．Blood pressure and pulse. |
| C．Blood pressure and cortiso1. | |
| D．Higher blood pressure and higher levels of the hormone. |
4.In what ways can anger be beneficial to people?
| A．By showing their optimistic side. | B．By reducing their stress. |
| C．By reducing high blood pressure. | D．By taking the place of fear. |
5.The researchers irritated（激怒）the students by __________.
| A．recording their performance secretly |
| B．asking them to count to 6, 200 again and again |
| C．disturbing them and making them start all over again |
| D．criticizing them when they made mistakes |
