Living in a city is a well-known risk factor for developing a mental disorder，while living close to nature is largely beneficial for mental health and the brain.A central brain region，the amygdala（大腦杏仁核）involved in stress processing，has been shown to be less activated during stress in people living in rural areas，compared to those who live in cities，hinting at the potential benefits of nature. "But so far the hen-and-egg problem could not be resolved，namely whether nature actually caused the effects in the brain or whether the particular individuals chose to live in rural or urban regions，" says Sonja Sudimac.
   To achieve causal evidence，the researchers from the group examined brain activity in regions involved in stress processing in 63 healthy volunteers before and after a one-hour walk in Grunewald forest or a shopping street with traffic in Berlin The results revealed that activity in the amygdala decreased after the walk in nature suggesting that nature elicits beneficial effects on brain regions related to stress.
   "The results support the previously assumed positive relationship between nature and brain health，but this is the first study to prove the causal link.Interestingly，the brain activity after the urban walk in these regions remained stable and showed no increases，which argues against a commonly held view that urban exposure causes additional stress，" explains Simone Kühn，head of the group.
   The authors show that nature has a positive impact on brain regions involved in stress processing and that it can already be observed after a one-hour walk.This contributes to the understanding of how our physical living environment affects brain and mental health.Even a short exposure to nature decreases amygdala activity，suggesting that a walk in nature could serve as a preventive measure against developing mental health problems and reducing the potentially disadvantageous impact of the city on the brain.
   In order to investigate beneficial effects of nature in different populations and age groups，the researchers are currently working on a study examining how one-hour walk in natural versus urban environments impacts stress in mothers and their babies.

1．    Reading is a complex and crucial skill that impacts the youth's ability to perform as students.Therefore，it's important to develop reading skills during childhood.A team of researchers focused on the effect of whole-body learning in instruction，known as embodied learning.
    The research included 149 children，aged 5 to 6，who had just started school.They were divided into three groups：one that stood up and used their whole bodies to shape letter sounds；a seated group that shaped letter sounds with their hands and arms；and a control group that received traditional，seated instruction during which they wrote letters by hand.
    "Our research showed that children who used their whole bodies to shape the sounds of letters became twice as proficient at letter sounds that are more difficult to learn as those who received traditional instruction" says PhD student Linn Damsgaard of UCPH's Department of Nutrition，Exercise and Sports.
    With regard to difficult letter sounds，she adds， "There are many difficult letter sounds in Danish.These sounds are particularly important because once children become skilled at them，they will be better readers.
    Associate professor Jacob Wienecke，who led the study，explains，the primary goal is to learn more about which methods can be used to give beginner readers a good start.The idea is that if，through play and movement，we can learn where their strengths truly lie，we'll create a form of learning that combines reading with play，and that's truly positive."
    Previously，the researchers showed that the children felt more motivated by teaching methods which included physical movement.Jacob Wienecke hopes this will provide an opportunity to inspire teachers and school managers to prioritize movement across subjects.
    The study also investigated whether a direct effect of embodied learning could be found on children's reading of words.This was not possible，which might be due to the fact that the children were at such an early stage of their literacy development that they could not yet use their knowledge of letter sounds to read words.

（1）What were the participants required to do in the study？

A．To pick out difficult letter sounds in Danish.
B．To learn new letters through repeated writing.
C．To learn letter sounds using different approaches.
D．To memorize some letter sounds as soon as possible.
（2）How can embodied learning get children actively involved？

A．By combining learning with games.
B．By offering them chances to cooperate.
C．By inspiring them to overcome difficulties.
D．By explaining instructions to them patiently.
（3）What does the underlined word "proficient" in Paragraph 3 probably mean？

A．terrible.
B．skilled.
C．delighted.
D．fascinated.
（4）What does Jacob expect of the research finding？

A．Encouraging educators to apply it to teaching.
B．Enabling researchers to carry out further studies.
C．Urging schools to pay attention to physical exercise.
D．Promoting harmonious teacher-student relationships.
（5）What does the last paragraph intend to tell us？

A．Children prefer learning step by step.
B．Children are too little to use their knowledge smartly.
C．Children lack enough practice to get fully improved.
D．Children's learning still relies on adults' instruction.

2．How to Work Out Your Worries by Writing
Something troubling you？You should write about it!Research indicates that people who write about a difficult situation often show improved mental and physical health.
   （1）

.It is a specific technique，and it's different from writing in a journal.The idea is to reflect honestly and thoughtfully on a particular challenge.
   Hundreds of studies over several decades have looked at the potential benefits of expressive writing.It can strengthen the immune system，including for people with illnesses such as flu，cancer and depression. （2）

   Expressive writing works because it allows you to make meaning out of a painful experience，experts say. （3）

Then translating that experience into language forces you to organize your thoughts.And creating a narrative gives you a sense of control.
   But expressive writing isn't a magical cure-all solution. （4）

.And people coping with a severe injury or depression may not find it useful to do on their own，without therapy （治療）.
   （5）

？Thinking or talking about an event can lead to reflecting，where you become lost in your emotions.Writing forces you to slow down.The mere act of labeling a feeling—of putting words to an emotion—can lessen the nervous activity in the threat area of the brain.Writing can increase someone's acceptance of his experience，and acceptance is calming.

A．Why write
B．What if you don't write
C．It can also help improve mood，sleep and memory
D．Expressive writing gave people the courage to face fears
E．It shouldn't be used as a replacement for other treatments
F．The first important step is to recognise what it is that is bothering you
G．Psychologists refer to writing about an unpleasant experience as "expressive writing"

3．At some time in your life you may have a strong desire to do something strange or terrible．However，chances are that you don't act on your impulse （沖動），but let it pass instead You know that to commit the action is wrong in some way and that other people will not accept your behavior．
One of the newest taboos in American society is the topic of fat．Unlike many other taboos，fat is a topic that Americans talk about constantly．It's not taboo to talk about fat；it's taboo to be fat．The "in" look is thin，not fat．In the work world，most companies prefer youthful-looking executives to sell their image as well as their products to the public．The thin look is associated with youth，vigor and success．The fat person，on the other hand，is thought of as lazy and lacking in energy，self-discipline and self-respect．In an image-conscious society like the US，thin is "in" but fat is "out"．
It's not surprising that millions of Americans have become crazy about staying slim and "in shape"．The pursuit of a youthful physical appearance is not，however，the only reason for America's fascination with diet and exercise．Recent research has shown the importance of diet and exercise for personal health．As in most technologically developed nations，the life style of North Americans has changed dramatically during the course of the last century．Modern machines do all the physical labor that people were once forced to do by hand．Cars and buses transport us quickly from point to point．As a result of inactivity，people's bodies can easily become weak and vulnerable （易受攻擊的）to disease．In an effort to avoid such a fate，millions of Americans are spending more of their time exercising．
