Is there anything more important than health? I don't think so. “Health is the greatest wealth.” wise people say. You can't be good at your studies or work well when you are ill. If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.    

    Speaking about doctor's advice, I can't help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat with pleasure, drink with pleasure and enjoy life as it is.” The doctor also said that if the man wanted to be well again, he shouldn't smoke more than one cigarette a day. A month later the gentleman came into the doctor's office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.“ But you know, doctor,” he said, “it's not easy to begin smoking at my age.”

    Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.

    The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

    Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.

    But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.

    There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

    French writer Frantz Fanon once said: ＂To speak a language is to take on a world, a culture.＂ Since the world changes every day, so does our language.

    More than 300 new words and phrases have recently made it into the online Oxford Dictionary, and in one way or another they are all reflections of today's changing world.

    After a year that was politically unstable, it's not hard to understand the fact that people's political views are one of the main drives of our expanding vocabulary. One example is ＂clicktivism＂, a compound of ＂click＂ and ＂activism＂. It refers to ＂armchair activists＂ — people who support a political or social cause, but only show their support from behind a computer or smartphone. And ＂otherize＂ is a verb for ＂other＂ that means to alienate (使疏远)people who are different from ourselves — whether that be different skin color, religious belief or sexuality.

    Lifestyle is also changing our language. For example, ＂fitspiration＂ — a compound of fit and inspiration — refers to a person or thing that encourages one to exercise and stay fit and healthy.

    The phrase ＂climate refugee＂ — someone who is forced to leave their home due to climate change—reflects people's concern for the environment.

 According to Stevenson, social media was the main source for the new expressions. ＂People feel much freer to coin their own words these days,＂ he said.

    But still, not all newly-invented words get the chance to make their way into a mainstream (主流的) dictionary. If you want to create your own hit words, Angus Stevenson, Oxford Dictionaries head of content development, suggests that you should not only make sure that they are expressive (有表现力的) and meaningful, but also have an attractive sound so that people will enjoy saying them out loud.

    One of the questions surrounding climate change is how it might affect the food supply for a growing global population. A new study suggests that researchers have been overlooking how two key human responses to climate—how much land people choose to farm, and the number of crops they plant—will affect food production in the future. The new study focused on the Brazilian state of Mato Grosso, an emerging（新兴的）global breadbasket（产粮地区）that as of 2013 supplied 10 percent of the world's soybeans. The researchers used variations in temperature and precipitation（降水）across the state over an eight-year period to estimate the sensitivity of the region's agricultural production to climate change. Those historical comparisons can help in making predictions about the sensitivity of agriculture to future climate change.

    The study found that, if the patterns from 2002 to 2008 hold in the future, an increase in average temperature in Mato Grosso of just 1 degree will lead to a 9 to 13 percent reduction in overall production of soy and corn. “This is worrisome given that the temperature in the study region is predicted to rise by 2 degrees by 2050,” said Avery Cohn, who led the study.

    Most studies of this kind look only at the extent to which climate shocks affect crop output. But researchers can miss critical dynamics（动力）that can affect overall output, says Leah VanWey, one of the study's senior authors. “If you look at output alone, you're not looking at all of the information because there are economic and social changes going on as well,” said VanWey.

    If output decreases, farmers may put less land area into production because it's not profitable. Farmers may also vary the number of crops they plant in a growing season. Double cropping is common in Mato Grosso. But if the weather is bad, farmers may change their decision to plant a second crop.

Teenage summer camps

    We helped on a nature reserve(保护区)for a week. We did different things every day, including cutting the reeds(芦苇),by the lake. Every day, we took turns to cook, in teams of five. When it was our teams turn, we made a simple dinner of pasta and salad for everyone. Judging by the fact that there was none left, we didn't do too badly!

    We stayed with families who had kids our own age, and because they were on a mid-term break they came with us on all the trips. So except when we were actually in a language class, we were spending time with our new friends. It was a great way to practice the language we had been working on in the classroom.

-Oliver

    Every morning we had the same breakfast, and then cleaned up the camp. When it was all completely tidy, we could head off for the day. The first time we went into the city, we were put into teams and given lists of things to spot, like statues, squares and other landmarks. With some help from the locals, my team found almost all of the things on our list and came second. We went to different museums and galleries in and around the city every day. It was a great chance to learn about another country and its history.

-Sarah

    We stayed in a youth center in the suburbs, and went into the center of town by bus every day. It was a good way to see a bit of the city, and it didn't take long to get to the theater where we had our classes. I loved the atmosphere in the old building, and we could walk around during our breaks and watch rehearsals(排练). We learned a great deal and I'm looking forward to putting it all into practice at my school drama club next term!

A researching team analyzed data from long-running studies conducted in Brazil and South Africa to assess whether children exposed to early adversities (逆境), such as extreme poverty, low birth weight, and pre-term birth, could reach their full learning potential by experiencing responsive caregiving and opportunities to learn in their home. They found that early life adversities matter throughout life. Teenagers who had been exposed to multiple adversities early in life had lower IQ scores, were more likely to have difficulties adjusting socially and psychologically, and achieved a lower physical height compared to teenagers exposed to fewer adversities. They also found that being raised in a nurturing (培育) environment could significantly counteract the negative effect of early adversities on IQ and help children achieve their full potential of intelligence.

Globally, more than 250 million children younger than 5 years are at risk of not reaching their developmental potential because of adversities that co-occur early in life and worsen with age. In the US, almost one in five children are raised in poverty and 15 percent do not complete high school. Exposing these children to a nurturing environment, whether at home or in daycare or pre-school settings, can lead to cognitive (认知的) benefits that last into teenage and beyond.

Parents should provide nurturing environments, which include interacting with young children in a positive way such as reading children's books from the library, singing songs together, and playing games with numbers and letters. Children who join in age-matched housework like picking up toys and clearing the table gain skills and feel good about helping. Get children involved in friendly activities as much as possible rather than park them in front of a screen. Children love to learn and in a nurturing environment, they can grow into teenagers and adults with the abilities to care for themselves, their families, and their communities.
