1 . With the weather getting colder and the days becoming shorter, some people are noticing they have less energy and aren’t feeling as positive as they usually do.
Researchers aren’t yet clear on what causes SAD, but it's likely to be complex. Some research suggests it could be due to a malfunctioning hypothalamus (下丘脑功能不全) or producing too much melatonin (a hormone which controls our sleep-wake cycle). Some researchers theorize it could also be due to having a disrupted circadian rhythm(昼夜节奏混乱).
Some people notice that their symptoms start to improve when the seasons begin to change and spring approaches.
Aside from seeking professional help, there are a couple of other things that people can do to help them cope with SAD during their day.
| A．Colder weather and less daylight may have you feeling a bit more down lately. |
| B．Research also shows that lifestyle factors can play an important role in both causing and managing depression. |
| C．According to one study, getting more natural light during the day may help improve symptoms. |
| D．Of course, there may be other factors at play too. |
| E．But this doesn’t mean that there aren't many things people can do during the winter months to help them cope with their symptoms. |
| F．While these feelings may be temporary for some, around one in three people consistently struggle through the autumn and winter months. |
| G．Light therapy is also currently being investigated as a treatment for SAD. |
2 . If you followed the 2016 Rio Olympic Games, you may have noticed that several athletes, including US swimmer Michael Phelps, had circular bruises on their bodies. These bruises were the results of “cupping therapy”, a traditional Chinese medical practice that has been around for more than 2,000 years.
Cupping therapy involves attaching circular cups to the skin using suction(吸力). The suction is created either by heating the cup inside or by using a handheld pump. This suction pulls the skin upward into the cup. Sometimes it can leave dark red bruises, other times there is no mark at all.
Many athletes say that they have benefited from the therapy. Phelps used the therapy in the fall of 2014 and has used it about twice a week since, reported ABC News. Another US swimmer, Dana Vollmer, also believes that “it really helps with blood flow, and helps pull swelling out of different areas.”
However, some have said that the supposed health effects result from people feeling that the treatment works, rather than any physical effects of the treatment.
To figure out whether cupping therapy has any physical effects, last year researchers from Germany carried out a test in which a sham(假装的) treatment was provided.
In the study, the same type of cups was used in the real treatment and the sham treatment. But in the sham treatment, the cups had a hole at the top so that they couldn’t create the proper suction.
The tested patients, who suffered from a disorder(疾病) that causes a lot of pain, were told that they would receive either a traditional cupping or “soft cupping”. But they were not informed that the so-called “soft cupping” was a sham treatment.
It turned out that most patients correctly guessed which kind of cupping they had received. In both groups, patients also experienced about the same reductions in pain. The results suggest the effects of cupping therapy might come fro factors that are not necessarily part of the treatment itself, the researchers told the Live Science website.
The question of whether cupping therapy works still needs to be answered. But because the treatment is relatively safe and it could be helpful for some people, “the therapy can be used as a part of a comprehensive treatment program involving other exercises, nutritional choices and lifestyle interventions(干预)”, Dr Brent Bauer, director of the US’ Mayo Clinic Complementary and Integrative Medicine Program, told Live Science.

3 . Paintings and sculptures can be a feast for the eyes of visitors to art museums, but today their viewing is also an unconventional treatment for people with mental illness.
Last month, a group of Canadian doctors started to write a new kind of prescription（处方）,which gives patients free access to the Montreal Museum of Fine Arts（MMFA）. There, they will have a "relaxing, revitalizing experience" looking at the museum's collections, according to MMFA.
Nathalie Bondil, the museum's director general, believes that being in contact with culture and arts can help with wellbeing. "In the 21st century, culture will be what physical activity was for health in the 20th century," she said.
Each prescription will allow not only the patients but also their families or friends to go with them. In the museum, the visitor can appreciate the artworks, and take part in a wide range of activities including drawing, sewing（缝纫）and making a sculpture with recycled materials.
The new treatment is said to be the first of its kind in the world. But there's increasing evidence that the display of visual art, especially art depicting（描绘）nature, can have positive effects on people with depression, anxiety and self-esteem（自尊）problems.
In 2017, the UK's All Party Parliamentary Group on Arts, Health and Wellbeing（APPGAHW）also released a report stating that "the time has come to recognise the powerful contribution the arts can make to our health and wellbeing".
Is it possible for art to improve overall health? We may not know the answer yet. But one thing is certain, more and more people today are persuaded by the idea that "art is good medicine".

4 . Close your eyes for a minute and imagine what life would be like if you had a hundred dollars less. Also imagine what it would be like spending the rest of your life with your eyes closed. Imagine having to read this page, not with your eyes but with your finger-tips.
With existing medical knowledge and skills, two-thirds of the world's 42 million, blind should not have to suffer. Unfortunately, rich countries possess most of this knowledge, while developing countries do not.
ORBIS is an international non-profit organization which operates the world's only flying teaching eye hospital. ORBIS intends to help fight blindness worldwide. Inside a DC-8 aircraft, there is a fully-equipped teaching hospital with television studio and classroom. Doctors are taught the latest techniques of bringing sight back to people there. Project ORBIS also aims at promoting peaceful cooperation among countries.
ORBIS tries to help developing countries by providing training during three-week medical programs. ORBIS has taught sight-saving techniques to over 3,000 doctors and nurses, who continue to cure tens of thousands of blind people every year. ORBIS has conducted 17 plan programs in China so far. For the seven to ten million blind in China ORBIS is planning to do more for them. At the moment an ORBIS is working on a long-term plan to develop a training center and to provide eye care service to Shanxi Province. ORBIS needs your help to continue their work and free people from blindness.
For just US$38, you can help one person see; for $380 you can bring sight to 10 people; $1,300 helps teach a doctor new skills; and for $13,000 you can provide a training program for a group of doctors who can make thousands of blind people see again. Your money can open their eyes to the world. Please help ORBIS improve the quality of life for so many people less fortunate than ourselves.

5 . In a major medical breakthrough, Tel Aviv University researchers have “printed” the world's first 3D vascularized (有血管的）engineered heart using a patient’s own cells and biological materials. Their findings were published on April IS in a study in Advanced Science.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” says Prof. Tal Dvir of Department of Materials Science and Engineering, who led the research for the study. “This heart is made from human cells and patient-specific biological materials. In our process, these materials serve as the bioinks, something made of sugars and proteins that can be used for 3D printing of complex tissue models，” Prof, Dvir says. “People managed to 3D print the structure of a heart in the past, but not with cells or with blood vessels (血管).Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”
According to Prof. Dvir，the use of “ native ” patient-specific materials is important to successfully engineering tissues and organs.
The researchers are now planning on culturing the printed hearts in the lab and “ teaching them to behave” like hearts, Prof. Dvir says. They then plan to transplant the 3D-printed heart in animal models.
“We need to develop the printed heart further，” he concludes. “The cells need to form a pumping ability ； they can currently contract (收缩），but we need them to work together. Our hope is that we will succeed and prove our method’s efficacy (功效)and usefulness. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world，and these procedures will be conducted routinely. ”

6 . First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. First aid may save a life or improve certain vital signs including pulse, temperature, a clear airway, and breathing. In minor emergencies, first aid may prevent a victim’s condition from worsening and provide relief from pain. First aid must be given as quickly as possible. In the case of seriously injured, a few minutes can make the difference between complete recovery and loss of life.
First aid measures depend upon a victim’s needs and provider’s level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury , for example, can lead to permanent spinal (脊柱的) injury and paralysis (瘫痪)。
Despite the variety of injuries possible, several basic rules of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious (有意识的), should be reassured that medical aid has been requested, and ask for permission to provide any first aid. Next, assess the scene, asking other people or the injured person’s family or friends about details of the injury or illness, any care that may have already been given, and preexisting conditions such as diabetes (糖尿病) or heart trouble. The victim should be checked for the medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim.
First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for assessing a victims condition is known by ABC, which stands for:
A — Airway: is it open and clear?
B — Breathing: is the person breathing? Look, listen, and feel for breathing.
C — Circulation: is there a pulse? Is the person bleeding extremely?
Check skin color and temperature for additional indications of circulation problems.
1. Before we give first aid to a victim, it is very important for us to ___________________.| A．make sure what to do and what not to do | B．refer to all kinds of handbooks on first aid |
| C．remove the ring or bracelet he/she may be wearing | D．take him/her to a hospital at once |
| A．professional doctors | B．the victim’s family members |
| C．the victim’s friends | D．those who are not necessarily professional doctors |
| A．Checking whether there is a pulse. | B．Looking, listening and feeling for breathing. |
| C．Replacing his/her medical card. | D．Examining whether the airway is open and clear. |
| A．the importance of protecting the accident scene. | B．some basic knowledge about first aid. |
| C．what professional medical help is. | D．who can give first aid. |
