The Alexander technique
Until earlier this year, I didn't know anything about the Alexander technique—and saw no reason to think I should. One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they'll go away, but I eventually went to the doctor. After examining me, he said, "You actually have bad posture (姿势). Go off and learn the Alexander technique." Three months later I could walk straighter and sit better.
The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercise-based. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly.
The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines.
So who was Alexander and how did he come up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (声音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teacher-training school, which is still successful today.
So if you're walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.

Kaitlin Woolley and Ayelet Fishbach report in Psychological Science that a meal taken "family-style" from a central plate can greatly improve the outcome of later negotiations.
Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the
way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity(短缺)and increase a feeling of competition. However, they also reasoned that it could instead lead people to become more aware of others' needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.
For the first test they recruited 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began.
The game asked the participants to negotiate an hourly wage rate during a fictional strike. Each person was randomly assigned to represent the union or management and follow a set of rules. The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster(in 8. 7rounds)than those who did not(13.2 rounds). A similar experiment was conducted with 104
participants and Goldfish crackers(饼干), this time negotiating an airline's route prices. The results were much the same, with the food-sharers negotiating successfully 63. 3%of the time and those who did not share doing so 42. 9%of the time.
(1)What does the "family-style" meal in the report refer to?
A. A meal taken at home.
B. A meal shared with others.
C. A meal consumed by oneself.
D. A meal taken in a family atmosphere.
(2)For what purpose did the researchers carry out the present experiments?
A. To show the way food is served.
B. To prove sharing food increases competition.
C. To confirm sharing food can promote cooperation.
D. To find out whether sharing food can get people close emotionally.
(3)Why were participants asked to eat up the snack before the game?
A. To add to their energy.
B. To reward them for their participation.
C. To hide the intention of the experiment.
D. To avoid the distraction during the game.
【答案】(1)B
(2)C
(3)C

Three-quarters of the world's coffee farms destroy forest habitat to grow coffee in the sun and typically use harmful pesticides (杀虫剂) and chemicals that poison the environment. When forests disappear, migratory (迁徙的) songbirds disappear, too. In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification.
Bird Friendly coffees are shade-grown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shade-grown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more complex flavor. Bird Friendly certified coffees grow under bio-diverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet.
Bird Friendly producers can also earn more for their crops. The wood and fruit trees on shade coffee farms provide farmers with additional income. Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat.
Buying Bird Friendly supports the Smithsonian Migratory Bird Center's conservation research aimed at understanding and protecting your feathered friends. You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup. Find a store or cafe near you, or better yet, have it shipped to your door when you order online.
(1)What is the present situation of coffee farms?
A. One fourth of them have destroyed forest habitat for birds.
B. Pesticides and chemicals used on them poisoned many birds.
C. Farmers have been aware of environment protection.
D. Scientists pay attention to them and have come up with an idea.
(2)What's a characteristic of Bird Friendly coffees?
A. They may have a better taste.
B. They have a strange flavor.
C. They take less time to ripen.
D. They are grown on unpolluted land.
(3)How can Bird Friendly farmers earn more money?
A. By charging consumers more money.
B. By selling fruits and wood from trees.
C. By cutting down trees and selling wood.
D. By serving as stewards of coffee consumers.(4)What does the text suggest coffee consumers do?
A. Consume less coffee.
B. Order coffee online.
C. Purchase shade-grown coffee.
D. Donate to coffee farmers.

4.犇犇Choose the one that fits best according to the information given in the passage you have just read.
Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people's increased positive outlook. Our research took us in the fascinating direction of exploring how the body uses its energy.
When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陈代谢) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing
energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energy-demanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you're being chased by a tiger, you don't need to waste energy making immune cells to fight off tomorrow's cold. What you need is to shift all available energy resources to your legs, with the hope that you will live to experience another cough or sneeze.
As a result, our immune system evolved to run in maximum amounts when we're happy, but to slow down dramatically when we're not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, becoming more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.
(1)According to Robert Trivers, when our body needs extra energy, ______.
A. muscles will respond to it by relaxing a little bit
B. organs will speed up metabolic processes to answer it
C. immune system will temporarily shut down to fulfill it
D. brain will satisfy it by sharing optional metabolic output
(2)In paragraph 3 "this relationship" most probably refers to the one between ______.
A. experiences and related knowledge
B. happiness and biological evolution
C. immune function and health
D. optimism and length of life
(3)What can be concluded from Robert Trivers' study?
A. Younger people adopt strategies of handling tense situations from everyday life.
B. Our ancestors evolved their immune systems in fighting against fierce animals.
C. Realizing that their days are numbered, older people prefer being positive.
D. Being negative drains energy from our body, lowering resistance to disease.
(4)Which of the following is the best title of the passage?
A. Brain, muscles and immune system
B. Age, health and happiness
C. Ancestors, emergency and evolution
D. Energy, effort and response

【解析】【分析】本文是一篇说明文,研究表明,老年人往往会记住生活中积极的事物,
而不是消极的事物。
十年前作者与生物学家罗伯特·特里弗斯合作研究身体是如何使用能量的,他们的发现解释了这一现象。
(1)考查推理判断。
根据第二段中的“We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function.”可知我们的身体里有大量的免疫细胞,暂时停止运作是可以的。
因此,当我们的身体需要额外的能量时,(我们的身体)会去找免疫系统。
由此可以推断,免疫系统会暂时停止来为身体提供额外的能量。
选C。
(2)考查词义猜测。
根据第三段中的 "becoming more focused on the positive things in life in an effort to enhance their immune functioning." 可知老人们更加关注生活中积极的事物,是为了增强他们的免疫功能。
也就是说积极与免疫功能之间有关系,越积极,免疫功能越强,就能活得越久,所有选项中D项(乐观与寿命)之间最切题,故选D。
(3)考查推理判断。
根据最后一段中的"As a result, our immune system evolved to run in maximum amounts when we're happy, but to slow down dramatically when we're not."可知当我们快乐时,我们的免疫系统进化到最大程度,但是当我们不快乐时,免疫系统会减弱。
由此推断,消极会消耗我们身体的能量,降低对疾病的抵抗力。
选D。
(4)考查主旨大意。
作者开头提出老年人更关注积极的事情,后文提到积极的情绪会增强免疫系统,所以本文主要讲的是年龄,健康与积极的情绪之间的关系,选B。
【点评】本题考点涉及推理判断,词义猜测和主旨大意三个题型的考查,是一篇科研类阅读,考生需要根据上下文的逻辑关系,进行分析,推理,概括和归纳,从而选出正确答案。

Experts note that an unhealthy lifestyle can put you at great risk of heart disease and stroke. So doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. But there is something else you can do. And it is free and easy. Smile!
Dr. Chockalingam, a heart disease specialist in Columbia, advises his patients to smile. He says a smile may be one way to help your heart. "When we smile, the brain wiring changes. The chemicals that are released are more positive." He says smiling is the first step in fighting physical and emotional stress and its sometimes harmful effects on human health. This is not just New Age advice. Several studies support his opinion.
When you feel stressed or under pressure, your body releases many natural hormones (荷尔蒙) including adrenaline and cortisol. Adrenaline increases your heart rate and blood pressure. Cortisol is the body's main stress hormone. It increases sugar in the bloodstream. If you are truly in danger, these hormones can help you. They are part of what we call our fight-or-flight response. However, when we are stressed for a long period, these stress hormones are ever-present in our bodies. And that, medical researchers warn, may lead to health problems.
Researchers say the connection between stress and heart disease is still unclear. However, they claim that when people are stressed for long periods of time, they may have an unhealthy lifestyle, which can lead to health problems.
Dr. Chockalingam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish ... smiling for seemingly no reason. But a smile does not involve drugs. It is not invasive like a surgical operation. It is free and it has no bad side effects.
"Once people smile, they are relaxing. This relaxation directly lowers blood pressure, improves sugar levels in the blood. If we are smiling, we are breaking that link between stress and health." And it just may provide a little extra protection to everyone's heart health.
(1)Which of the following agrees with Dr. Chockalingam's opinion?
A.Smile has the same effects as laughter.
B.Smile can be used to take the place of medicine.
C.Smile is better than any healthy lifestyle to health.
D.Smile can make our body produce beneficial chemicals.
(2)What can we know about the mentioned stress hormones?
A.They can lower our blood pressure.
B.They will surely lead to heart diseases.
C.They can benefit us when we are in danger.
D.They will make us live an unhealthy lifestyle.
(3)Why does Dr. Chockalingam think smiling is helpful to our health?
A.It can make us relax.
B.It increases sugar levels.
C.It has little bad side effects.
D.It can happen for no reason.
(4)What can be the best title for the text?
A.A Thorough Analysis of the Causes of Heart Diseases
B.One Thing You Can Do Right Now to Help Your Heart
C.One Thing That Is Closely Connected with Stress Hormones
D.The Clear Connection Between Unhealthy Lifestyles and Heart Diseases
【答案】(1)D
(2)C
(3)A
(4)B

In 1953, a mountain climber reported seeing a bar-headed goose soar over the peak of Mount Everest (珠穆朗玛). It was thought impossible. Now researchers who raised 19 of the geese—named for the black stripes on the backs of their heads—have shown the birds really fly so high. The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模拟)10w-, medium-, and high-altitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel.
Birds already have a better heart and lungs than mammals for sustained physical activity. And researchers knew that bar-headed geese have even larger, thinner lungs that let them breathe more deeply and an even bigger heart to pump more oxygen to muscles than other birds.
The wind tunnel experiments showed that when the concentration of oxygen was at its lowest-like the 7% found on top of Mount Everest versus 21% at sea level—the geese's heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their blood-the measured blood temperature dropped so it could take in more oxygen, the researchers report today in eLife. This cooling likely helps compensate for the very thin air, the team says.
Although well trained, the birds were only willing to stay in the air a few minutes-or less when wearing their backpacks and flying at 6ihigh" altitudes. So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.(1)Why did the researchers raise 19 bar-headed geese and train them?
A. To test the flying height and speed of them.
B. To confirm they could fly over Mount Everest.
C. To observe them flying through the wind tunnel.
D. To see how many calories they burned per hour.
(2)What can we learn from the wind tunnel experiment?
A. It was carried out at very high altitude.
B. The geese managed to breathe less when their blood decreased.
C. The geese could live through the lowest concentration of oxygen.
D. It shows the geese could fly at high altitude for long.
(3)What still puzzles scientists about the geese?
A. Whether they have super hearts and lungs.
B. Whether they have muscles pumped more oxygen to.
C. Whether they are willing to wear backpacks and face masks.
D. Whether they can manage to fly 8 hours to climb over Mount Everest.
(4)Where does the text most probably come from?
A. A science fiction.
B. A climbing guide.

结果发现这种鹅可以在氧气极低的情况下飞行,但停留时间只有几分钟,因此能否飞过珠峰尚不明确。
(1)考查推理判断。
根据第一段中的"In 1953, a mountain climber reported seeing a bar-headed goose soar over the peak of Mount Everest. It was thought impossible." 报道说,一名登山者看到一只斑头鹅飞过珠穆朗玛峰。
人们认为这是不可能的;以及" Now researchers who raised 19 of the geese-named for the black stripes on the backs of their heads-have shown the birds really fly so high."现在研究人员饲养了这种鹅,他们发现这些鹅真的飞得很高。
再根据最后一段中的"So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest."但是否能让这种鹅飞8小时爬上珠穆朗玛峰尚不清楚。
由此可推断出研究人员饲养这种鹅是为了证实这种鹅是否能飞过珠峰。
故选B。
(2)考查推理判断。
根据第四段中的"The wind tunnel experiments showed that when the concentration of oxygen ...the geese's heart rate and frequency of wing beats remained the same even as their metabolic rate dropped....the researchers report today in elife. This cooling likely helps comp"可知风洞实验表明,当氧气浓度最低时,鹅的心率和翅膀搏动频率保持不变,即使它们的新陈代谢率下降。
研究人员今天在《伊利费》杂志上报道说,...这种降温可能有助于补偿空气的稀薄;第五段中的"Although well trained, the birds were only willing to stay in the air a few minutes-or less ..." 尽管训练有素,但这些鸟只愿意在空中呆上几分钟。
这两处综合推断出,鹅可以在最低浓度的氧气中生存。
故选C。
(3)考查推理判断。
根据最后一段中的"So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest." 可知,目前尚不清楚的是,只有这些适应性变化能否可以飞行8小时爬上珠穆朗玛峰。
故选D。

According to a team of researchers, an animal's ability to perceive(感知)time is linked to their pace of life.
"Our results lend support to the importance of time perception in animals where the ability to perceive time in a very short time may be the difference between life and death for fast moving creatures." commented lead author Kevin Healy from Trinity College Dublin.
The study was done with a variety of animals using phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans.
One example of this phenomenon at work, the authors say, is the housefly and its ability to avoid being hit. The research showed flies "observe motion in a shorter time than our own eyes can achieve, "which allows them to avoid being hit.
Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly on the research project, said in a statement, "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly."
In comparison, the tiger beetle(虎甲虫)runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey's(猎物)position.
Our results suggest that time perception offers an as yet unstudied dimension along which animals can specialize and there is considerable range to study this system in more detail.
(1)What is the research mentioned in the passage mainly about?
A. Pace of life of animals.
B. Impressive abilities of animals.
C. Lifetime of small animals.
D. Time perception of animals.
(2)What does Kevin Healy's comment mean in Para.2?
A. The survival of fast moving animals relies on their ability to perceive time.
B. Animals with quicker pace of life have better perception of time.
C. The ability of animals to perceive time depends on their high moving speed.
D. Animals with poor ability of time perception have a shorter life.
(3)Why can houseflies avoid being hit?
A. They can think very deeply before they act.
B. They can process the information as quickly as they receive it.
C. They can fly much faster than their eyes can keep up.
D. They can send information to brain more quickly than to their eyes.。
