In Wiltshire, England, volunteers are needed to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is started by an environmental protection organization, which has contributed to improving the living environment for wild animals. Recently the organization has asked volunteers to help it observe environmental changes based on the record of butterflies and protect the environment.
In the area, the local people have planted many special flowers with the help of the organization, aiming to see whether these flowers will interest the rare and beautiful butterflies. The project officer Sarah Marshall says, "It will be a suitable habitat(栖息地) for butterflies. They are great 'indicator species' as they are easily affected by weather changes so they make an early-warning system for the environment." She also points out that volunteers are needed to record the number or species of butterflies, and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time.
The organization is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed way and record the different butterflies they met along the way. Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife.
No experience is necessary as training and support will be provided, but an interest is important. If you are interested, please contact Sarah on (01380) 725670, exe 278, email sarah@ wiltshirewildlife.org.

【推荐1】William Dunn is the founder of Take a Kid Fishing, a nonprofit (非营利的) organization in Lakeland, Florida, which teaches poor and fatherless kids through the sport of fishing.
A dozen years ago, inspired by his six-year-old fatherless neighbor, Camran, who got angry and shouted at his mom, William asked Camran’s mom for permission to take Camran fishing. Camran was “hooked” from that first trip. The two fished together several times a week, and William saw positive changes in Camran’s behavior. “That’s when I realized that I had the duty to help fatherless kids,” he says.
On weekends, William and a few other volunteers take 20 to 25 kids out fishing on a rental boat, which was supported by the captain of the Double Eagle. Many have never been fishing or even on a boat, so William —or Big Will, as the kids call him —starts by teaching the basic skills. Then come the life lessons that fishing offers: patience, team work and the simple joy of relaxing in the outdoors. Take a Kid Fishing has taken more than 600 fishing trips with almost 2,000 kids who don’t have a father in their lives.
He wants to share his love of fishing with kids who don’t have a father to take them. “I just want to show them that I care about them, that I’m there for them,” he says. Because many kids go on many trips, William is able to build relationships with them. He and Camran, now 20, still regularly fish together, and Camran sees Big Will as a father figure.
Take a Kid Fishing has a huge impact, but it started because William wanted to help one kid. Do you know a child who might benefit from your friendship? Introduce them to fishing or another hobby you enjoy. You can make a great difference to their life.

【推荐2】Like many new graduates, I left university full of hope for the future but with no real idea of what I wanted to do. My degree, with honors, in English literature had not really prepared me for anything practical. I knew I wanted to make a difference in the world somehow, but I had no idea how to do that. That’s when I learned about the Lighthouse Project.
I started my journey as a Lighthouse Project volunteer by reading as much as I could about the experiences of previous volunteers. I knew it would be a lot of hard work, and that I would be away from my family and friends for a very long time. In short, I did not take my decision to apply for the Lighthouse Project lightly. Neither did my family.
Eventually, however, I won the support of my family, and I sent in all the paperwork needed for the application. After countless interviews and presentations, I managed to stand out among the candidates and survive the test alone. Several months later, I finally received a call asking me to report for the duty. I would be going to a small village near Abuja, Nigeria. Where? What? Nigeria?I had no idea. But I was about to find out.
After completing my training, I was sent to the village that was small and desperately in need of proper accommodation. Though the local villagers were poor, they offered their homes, hearts, and food as if I were their own family. I was asked to lead a small team of local people in building a new schoolhouse. For the next year or so, I taught in that same schoolhouse. But I sometimes think I learned more from my students than they did from me.
Sometime during that period, I realized that all those things that had seemed so strange or unusual to me no longer did, and returned to the United States a different man. The Lighthouse Project had changed my life forever.

Long ago in a small town, there was a place known as the House of 1,000 Mirrors. A small, happy little dog learned of this place and decided to visit it.
When he arrived, he bounced(跳) happily up the stairs to the doorway of the house. He looked through the doorway with his ears lifted high and his tail wagging as fast as it could. To his great surprise, he found himself staring at 1,000 other happy little dogs with their tails wagging just as his. He smiled a great smile, and was answered with 1,000 great smiles just as warm and friendly. As he left the house, he thought to himself, “ This is a wonderful place. I will come back and visit often.”
In this same village, another little dog, who was not quite as happy as the first one, decided to visit the house. He slowly climbed the stairs and hung his head low as he looked into the door. When he saw the 1,000 unfriendly looking dogs staring back at him, he growled at them and was horrified to see 1,000 little dogs growling back at him. As he left, he thought to himself, “This is a horrible place, and I will never go back there again.”

【推荐2】While it remains debatable whether animals really feel what we call love, hate and happiness, the following might be yet more proof that humans are not the only creatures capable of emotions.
A friend in need
While some cats might spot a helpless baby chicken and think “lunch", an orange kitten in Russia saw a friend in need of a helping paw. Baby chickens are particularly vulnerable to attacks from rats and other vermin (害兽), but this little chick stayed safe thanks to its energetic feline (猫科的) bodyguard.
We’ve got each other
On an island off the coast of China, a little macaque (猕猴) was seen resting its head on a dove. Having got lost, the macaque was found and taken in by the staff of an animal protection center. It soon became friends with the white dove, which had also been adopted by center staff. For two months they ate together and slept together.
Fast friends
When baby elephant Themba’s mother died, the veterinary (兽医的) team at Shamwari Game Reserve in South Africa hoped another elephant would adopt the orphan, but none would feed him. The team took the baby elephant in, giving him constant care and attention, but Themba was too distressed to eat. Fearing he would starve to death, the team introduced him to a sheep called Albert, who they hoped could provide companionship for Themba. Despite some initial tension, the two quickly became inseparable and Themba finally started eating.
A strong bond
Koko the gorilla, one of the most studied primates (灵长类动物) in history, communicated in American Sign Language. Koko asked for a cat in 1984. She chose a grey kitten and called it All Ball. Koko took care of All Ball as if it were a baby gorilla, and would appear distressed when parted from it. When All Ball was hit and killed by a car, Koko was seen mourning (哀悼) the cat's death.
1. Why did Themba remained hungry in the beginning? Because________.A.the staff members were unable to feed him. | B.he didn’t get on well with his new friend. |
C.he lost his parent and was too sad. | D.he got lost from his mother. |
A.Koko formed a close relationship with All Ball |
B.All Ball suffered attacks from other vermin. |
C.All Ball got parted from its mother gorilla. |
D.Koko liked communicating with All Ball in sign language. |
A.Animals are not capable of emotions. |
B.Friendship actually knows no boundaries. |
C.kittens are most likely to make friends with other animals. |
D.None of the friends in the passage liked each other at first. |
【推荐3】Feeding bread to the ducks is a fond pastime for many of us, reminding us of our happy childhood trips to the local park. But did you know that bread actually poses a danger to birds, as well as the environment? Eating it can cause our feathered friends to develop a condition called Angel Wing, which is when too much bread makes birds’ feathers grow too quickly. This additional weight puts a strain on their muscles, causing their wings to twist and drop open, and if not treated fast, they can lose the ability to fly.
“Angel Wing can be remedied if we reach birds before it has developed too severely,” says Caroline Simpson, a trustee of UK charity Swan Lifeline, which has rescued and treated more than 30,000 birds over the last 20 years. “Otherwise the consequence can be awful—such as amputations(截肢)of the wing.” Adult swans can also develop gut and heart disease, so it’s important we do our bit to prevent this by feeding wild birds with the right kind of food.
Bread can also cause harmful changes to the natural ecosystem. Rotting bread at the bottom of rivers and lakes allows bacteria to breed, spreading disease and attracting rats and other vermin to our waterways. It can result in algal(藻类的)blooms and the presence of a mould(霉菌)called Aspergillus too, which has the potential to kill waterfowl(水禽)and other wildlife if it gets into their lungs.
But this doesn’t mean we have to stop fun trips to feed the ducks. Giving birds the right food-like frozen peas, sweetcorn and lettuce leaves-is good for both them and the environment. So, next time you visit your local park, take a healthier alternative with you and do your bit to protect our precious wildlife.

【推荐1】World Environment Day is celebrated annually on June 5th and was created to inspire people around the globe to take an active part in environmental protection and learn more about ways we can help to guarantee the future of our planet is safe.
The very first World Environment Day took place in 1974, established by the United Nations General Assembly on the first day of the Stockholm Conference on the Human Environment that took place in 1972. Each year the United Nations picks a theme and a host city where anyone who is concerned about the environment can talk about environmental topics with others, followed by different kinds of exhibits to promote environmental awareness. Environmentalists, academics and scientists come together to bring new ideas on the table concerning the environment.
The 2018 World Environment Day was hosted by India, and the theme was Beat Plastic Pollution. It urged people to explore and choose supportable alternatives like paper or cloth bags to reduce the production and use of disposable plastic, which made up 10% of all of the waste. Even though the United Nations picks a specific host city every year, people around the world still celebrate World Environment Day in their hometowns with parades (游行), concerts, cleaning up, tree planting and all kinds of green actions to work towards having a beautiful planet and battling pollution.
World Environment Day is not a public holiday, so you won’t be getting the day off work or school, but if you want to celebrate, why not bring it to the attention of your parents, friends, colleagues or classmates? World Environment Day is all about working together to take action for the planet, so try to get everyone you know interested in helping do something. Things as small as making sure people have a way to recycle can make a difference. You could also try beautifying your neighborhood by planting gardens, learn about green foods, raise money for a local wildlife conservation group or simply learn about the effects of different products on the earth.

【推荐2】The Value of Tears
Tears can ruin make-up, bring conversation to a stop, and give you a runny nose. Tears leave you embarrassed and without energy. Still, crying is a fact of life, and your tears are very useful. Even when you’re not crying, they make a film over the eye’s surface.
When tears fall, they reduce stress. But we tend to fight them for all sorts of reasons. “People worry about showing their emotions, afraid that once they lose control they’ll never get it back.”
Sometimes people become much stressed and can’t cry. Whatever emotion they are feeling—shock, anger, fear, or sadness—is being held back.
But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry.
In certain situations, such as at work, tears are not appropriate. It’s good not to cry during a tense business discussion.
Tears are a sign of our ability to feel. If you find yourself near someone crying, deal with it. And never be afraid to cry yourself.
A.They too may be holding back a need to cry. |
B.They cry for different reasons. |
C.She gives crying exercises. |
D.It contains a chemical against infection. |
E.The fact is that no emotion lasts forever. |
F.It forms in response to the stress on the surface of the eye. |
G.But once you’re safely behind closed doors, don’t just cry. |
【推荐3】Recently the term “climate anxiety” has been used to better describe our growing concerns about climate change. While there is evidence that climate anxiety can be identified and reliably measured, what’s less clear is how it relates to mental illness. Mental health providers across the world are noting the presence of climate anxiety in their patients; however, the degree to which it is influencing mental illness is not yet clear, though evidence addressing this question is slowly growing.
For years now, mental health clinicians have seen climate anxiety influencing presentations of mental illness in a variety of ways, some extreme. Recent studies are starting to look at links between climate anxiety and mental illness in larger samples to help better understand the directionality of their relationship. In a U.S. survey of more than 340 people published in 2018, climate concerns were associated with depressive symptoms (症状). Ecological coping, which includes pro-environmental behaviors such as reducing energy consumption, appeared to be protective against depression, indicating that climate concerns and the poor coping skills used to address them could be causing depressive symptoms.
So who might be more at risk of mental illness secondary to the uncertainties around climate change? Unsurprisingly, climate anxiety appears higher in individuals with more concern about environmental issues at baseline and those already experiencing direct effects of climate change. Climatologists also face increased risk given their in-depth knowledge on the issue coupled with the upsetting task of trying to convey it to individuals and governments that often deny or downplay it. People with high levels of neuroticism, a personality trait that increases susceptibility to mental illness, are also likely to be at high risk.
Some individuals report adaptive responses to climate anxiety like adopting pro-environmental behaviors and participating in collective action, while others are unable to respond behaviorally at all. It’s not yet clear how these varying reactions manifest (呈现) on a population level and how they’re influencing humanity’s response to climate change. However, a recent survey of nearly 200 people found that, while climate anxiety was associated with an emotional response to climate change, it was not correlated with a behavioral response.
If this is true for humanity as a whole, we must urgently help motivate the anxious among us. Doing so successfully will require many approaches, such as delivering cognitive-behavioral therapy (认知行为疗法) to the most severely affected and demonstrating to entire populations that change is possible by better publicizing productive efforts by organizations to reduce their carbon footprints. We can’t let climate anxiety stop us from responding to climate change, because now, more than ever, we need action, not inaction.

【推荐2】The CCU (Charity Cycling UK) recently called on to raise awareness (觉察,意识)of dooring after discovering that many people don’t know what it is. Dooring is when a driver or passenger opens the door into another road user (typically cyclist) without looking for other road users.
The CCU chief officer Paul told Glou Live: Some people seem to see car dooring as a bit of a joke, but it’s not and can have serious results. We want to see great awareness made about the dangers of opening your car door carelessly, and people to be encouraged to look before they open. w Among the 3,000 injuries, 2,009 were cyclists, resulting in five deaths but this might not be the whole of the danger. Not all car dooring incidents will be attended by police, so the CCU has written to call for a public awareness campaign urging(敦促)all car users, not just drivers, to look before opening vehicle doors.
One of the ways the CCU suggests is the “Dutch reach”, where people leaving a vehicle reach over and use the non-door side hand to open the door. In the Netherlands they are known for practicing a method, known sometimes as the “Dutch reach”, which we think could be successfully encouraged in the UK. If you're really concerned about opening a door into the path of a cyclist coming behind you, consider using what’s known as the “Dutch reach” to open the door. That will naturally turn you in your seat and give you a much better view of what's coming up alongside in the car.

【推荐3】Teenagers who talk on the cell phone a lot, and hold their phones up to their right ears, score worse on one type of memory test. That’s the finding of a new study. That memory impairment might be one side effect of the radiation (放射线) that phones use to keep us connected while we’re on the go.
Nearly 700 Swiss teens took part in a test of figural memory. This type helps us remember abstract (抽象的) symbols and shapes, explains Milena Foerster. The teens took memory tests twice, one year apart. Each time, they had one minute to remember 13 pairs of abstract shapes. Then they were shown one item from each pair and asked to match it with one of the five choices. The study volunteers also took a test of verbal memory. That’s the ability to remember words. The two memory tests are part of an intelligence test. The researchers also surveyed the teens on how they use cell phones. And they got call records from phone companies. The researchers used those records to figure out how long the teens were using their phones. This allowed the researchers to work out how big radiation exposure (接触) each person could have got while talking.
A phone user’s exposure to the radiation can differ widely. Some teens talk on their phones more than others. People also hold their phones differently. If the phone is close to the ear, more radiation may enter the body, Foerster notes. Even the type of network signal that a phone uses can matter. Much of Switzerland was using an older “second-generation” type of cell phone networks, the study reports. Many phone carriers (通讯公司) have moved away from such networks. And more companies plan to update their networks within the next few years.
The teens’ scores in the figural memory tests were roughly the same from one year to the next. But those who normally held their phones near the right ears, and who were also exposed to higher levels of radiation, scored a little bit worse after a year. No group of teens showed big changes on the verbal memory test. Why might one type of memory be linked to cell phone use, but not another? Foerster thinks it could have to do with where different memory centers sit in the brain. The site that deals with the ability to remember shapes is near the right ear.
