Going green seems to be fad(时尚)for a lot of people these days.Whether that is good or bad，we can't really say, but for the two of us，going green is not a fad but a lifestyle．

    On April22nd，2011，We decided to go green every single day for an entire year．This meant doing 365 different green things，and it also meant challenging ourselves to go green beyond easy things．Rather than recycle and reduce our energy, we had to think of 365 different green  things to do and this was no easy task．

    With the idea of going green every single day for a year .Our Green Year started．My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment．We wanted to push the message that every little bit helps．

    Over the course of our Green Year, we completely changed our lifestyle．We now shop at organic(有机的) stores．We consume less meat, choosing green food．We have greatly reduced our buying we don't need．We have away half of what we owned through websites．Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made flesh bread .In our home office anyone caught doing something ungreen might be punished．

    Our minds have been changed by Our Green Year．We are grateful for the chance to have been able to go green and educate others .We believe that we do have the power to change things and help our planet．

    Hidden from the noise of Washington, D.C., Hillwood Museum is a special treasure. It contains (包含) one of the finest personal collections (收藏) of Russian and French art in the world.

    Hillwood Museum was once the home of Marjorie Merriweather Post. She was a rich businesswoman. She owned one of the largest food companies in the United States. She was also very interested in collecting beautiful French art and furniture.

    She moved to Russia in the 1930s as her third husband, Joseph Davies, became the American ambassador (大使) in Moscow. Marjorie Merriweather Post had a love for Russian art as well. She bought the house in Washington in 1955 and she wanted to make it into a museum after her death. Many art experts helped Mrs. Post create its fine collection.

    Hillwood has many rooms which are filled with her treasures. Visitors can see beautiful music boxes from the eighteenth century and colorful paintings of European princesses (公主). Experts say the ancient wood and gold furniture from France is some of the finest ever made. Visitors can even look at Mrs. Post's jewels and clothes.

    The museum also has several beautiful gardens. One is designed like the gardens in Japan. It has a bridge and visitors can watch flowers floating in the water. Flowers are also grown all the year in a special glass building or greenhouse. These flowers are placed in the house throughout the year.

After a walk, visitors can rest at a nearby eating place. They can also buy objects to remember this special museum.

    For as long as we've known about it, humans have searched for a cure for cancer. Across the world, countless amounts of time and money have been spent on researching a way to stop this terrible disease. But now, it seems like the answer could have been inside our own bodies the whole time.

    Recently, the Food and Drug Administration (FDA) in the US, a government agency that's responsible for healthcare, approved a new form of gene therapy (疗法) that could mean the end of a certain type of cancer.

    The therapy allows scientists to "train" the immune (有免疫力的) cells of sick patients to fight leukemia (白血病)—a form of blood cancer that mostly affects young people.

    The exciting new treatment works by removing healthy immune cells from the patient, known as T-cells, which are then changed to be able to "hunt down" cancer cells.

    The cells are then put back into the patient before they begin to get rid of the patient's leukemia over time, similar to how the body fights off other illnesses.

    "This is truly an exciting new day for cancer patients," Louis J. DeGennaro, president of the Leukemia and Lymphoma Society, said in a news release.

    Up until now, a long and painful marrow transplant (骨髓移植) was the only option for many leukemia patients.

    In this procedure, healthy blood cells are taken from a donator and placed into the sick patient, who also has to go through chemotherapy (化疗) to allow their body to adjust to the new cells.

    But with a recovery rate of around 83%—according to a news release published by the FDA—it's hoped that the days of painful trips to the hospital, or even death, are over for leukemia sufferers.

    "We're entering a new frontier in medical innovation (创新) with the ability to reprogram a patient's own cells to attack a deadly cancer," FDA representative Scott Gottlieb said in the release. "New technologies such as gene and cell therapies hold the potential to transform medicine and our ability to treat and even cure many incurable illnesses."

    If you'd like to go travelling, the following World Heritage Sites may be your best choices.

    Jiuzhaigou Valley Scenic and Historic Interest Area

    Jiuzhaigou Valley, which lies in the northern part of Sichuan Province, China, reaches a height of more than 4, 500m, with a series of different forests ecosystems. It's especially famous for its narrow landforms and excellent waterfalls. Some 140 kinds of birds also live in the valley, as well as a number of endangered plants and animals, including the giant panda. Jiuzhaigou Valley was recognized as a World Heritage Site by UNESCO in 1992.

    Khami Ruins National Monument

    The city of Khami, which developed after the capital of Great Zimbabwe had been given up in the mid-16th century, is of great archaeological (考古的) interest. The discovery of objects from Europe and China shows that Khami was a centre for trade over a long period of time. It joined the World Heritage List in 1986.

    Henderson Island

    Henderson Island, which lies in the eastern South Pacific, is one of the few atolls in the world whose ecology (生态) has been untouched by humans. It is famous for the 10 plants and 4 birds that can only be seen on the island. It was recorded in the World Heritage List in 1988.

    Old City of Jerusalem

    As a holy city for three different religions (宗教) in the Middle East, Jerusalem has always been of great religious importance  It was given a World Heritage status in 1981 and placed on the "List of World Heritage in Danger" the following year.

    Cooking programs and classes for children seem to positively influence children's food preferences and behaviors, according to a recent review. And, although the review didn't look at long-term effects of such programs, the findings suggest that such programs might help children develop long-lasting healthy habits.

    This research comes at a time when childhood obesity(肥胖) rates have been rising rapidly. More than one-third of adolescents in the United States were obese in 2012, according to the U. S.Centers for Disease Control and Prevention (CDC). This trend has been caused, at least in part, by a significant decrease in the amount of meals that people consume at home since the 1980s, according to background information in the study.

    Cooking education programs, such as Food Explorers, teach children about new healthy foods and how to prepare them. They also stress the importance of eating five fruits and vegetables every day. A volunteer parent explains a new food to the group, and the kids make something based on the lesson, such as fruit or vegetable salad. Depending on the program, kids may be sent home with information about healthy foods to bring to their parents, the review explained.

    The study team reviewed eight other studies that tested different types of cooking education programs. Children in these classes were between 5 and 12 years old, according to the review. The goal of the study team was to learn more about developing an efficient program to encourage healthy food choices that last a lifetime. The study found that it is particularly important to expose kids to healthy foods on a number of occasions. This makes them feel comfortable with the new foods, which helps them build healthy habits.

    The study stressed the importance of getting parents involved in(参与) their children's eating habits. Parents who are unable to enroll their kids in a cooking class can achieve similar benefits by having their kids help them while they prepare meals at home. Children are more comfortable at home, which makes them more receptive to new foods because they will make the connection to a positive experience.

Adults check their phones, on average,360 times a day, and spend almost three hours a day on their devices in total. The problem for many of us is that one quick phone-related task leads to a quick check of our emails or social media feeds, and suddenly we've been sucked into endless scrolling.

It's an awful circle. The more useful our phones become, the more we use them. The more we use them, the more we lay neural（神经的） pathways in our brains that lead to pick up our phones for whatever task is at hand-and the more we feel an urge to check our phones even when we don't have to.

What we do know is that the simple distraction of checking a phone or seeing a notification（通知）can have negative consequences. This isn't very surprising; we know that, in general, multitasking does harm to memory and performance. One of the most dangerous examples is phone use while driving. One study found that merely speaking on the phone, not texting, was enough to make drivers slower to react on the road. It's true for everyday tasks that are less high-risk, too. Simply hearing a notification "ding" made participants of another study perform far worse on a task-almost as badly as participants who were speaking or texting on the phone during the task.

It isn't just the use of a phone that has consequences-its me re presence can affect the way we think.

In one recent study, for example, researchers asked participants to either put their phones next to them so they were visible（like on a desk）, nearby and out of sight（like in a bag or pocket）, or in another room. They were found to perform far better when their phones were in another room instead of nearby-whether visible, powered on or not.
