    We meet on Mondays at 14：30 at the IWC clubhouse. We chat for about an hour and discuss everything. Mandi asks “students” to contact her on Monday to confirm the class as sometimes she needs to cancel for various reasons or occasionally she may choose to hold the class at a different venue(举办地点) or at an earlier time for us to be able to have lunch together.

    The group meets on Thursday afternoons from 15：00－16：30 at the clubhouse. The first half of the class is devoted to reading out loud from the book “Easy French Reader”, working on pronunciation and phrasing. During the second half, we listen to audio recordings from “New French with Ease” and work on oral comprehension.

French Conversation, Advanced

Leader: Juliette Brull

    We meet every Tuesday at the IWC clubhouse from 9：30－11：00. Most of our time is devoted to very lively discussions about current events and various topics. We also read a book written by a French author and sometimes we see a French movie.

    The discussion on renewable energy has been going on for at least a decade and people have relied on fossil fuels almost entirely for more than a century. However, the situation when fossil fuels were the most efficient and the cheapest source of energy has been left far in the past. Many countries such as Germany and Sweden have already made significant efforts to fix this situation, employing numerous power plants working on the renewable resources of energy. The most effective among these resources is geothermal（地热的）energy.

    Geothermal energy does not depend on the world's economic and political situation as strongly as fossil fuels do. Besides, extracting（提炼）fossil fuels adds to the price of energy produced from them. Therefore, geothermal energy is much cheaper than traditional ones, saving up to 80% of the costs over fossil fuels.

    Being a renewable resource, geothermal energy produces less waste and pollution than traditional energy sources. In geothermal systems, carbon dioxide makes up about 10% of air produced. Overall, in order to produce the electricity that can be used for one hour, the geothermal systems produce 0.1 pound of carbon dioxide and other harmful gases. For a comparison, a power plant producing from gas produces up to 2 pounds of carbon dioxide into the atmosphere, and those power plants that work on coal（煤）produce an astonishing 3.6 pounds of greenhouse gases.

    Low costs is another reason why using geothermal power plants should be the first choice for many countries. Geothermal heat systems require 25% to 50% less energy for work compared with the traditional systems for heating or cooling. Besides, geothermal equipment is less big: due to the very nature of geothermal energy, geothermal power plants have only a few moving parts, all of which can be easily sheltered inside a relatively small building. What's more, the life span of geothermal equipment is rather long. All these make geothermal power stations easy to build and keep.

    A new high tech mirror, designed specifically for cancer patients, will only become reflective when a user smiles into it. The plug-in device, which exactly looks like a tablet, comes equipped with a mirror, a built-in camera, and a smart material triggered(触发)by some software. Facial recognition technology captures the face and instructs the surface of the mirror to change when a smile is detected. It can hang on a wall or sit on a table, much like a conventional mirror. Unlike a regular mirror, however, the price is currently standing at a surprising $2000—$3000.

    After witnessing a close family member struggle through cancer treatments, Turkish industrial designer Berk Ilhan decided to focus his work primarily on products that would cultivate joy and benefit cancer patients directly.

    “She told me in the first days after her diagnosis, it was difficult for her to look in the mirror and acknowledge she had cancer.” he said.“ Our facial expressions affect how we feel. If we flex(绷紧)our facial muscles to smile, our brains think that something good happened and as a result, we feel happiness.”

    After earning his master's degree at the School of Visual Arts in New York, Ilhan spent several weeks visiting cancer hospitals in Turkey, speaking to both patients and doctors. He spent two years designing and developing the mirror. The idea behind it is that smiling, even when forced, can make us feel better, according to research known as the facial feedback hypothesis. Laughter is linked to improved immune system function, and some researchers claim it can even increase our lifespans.

Ilhan is currently producing the mirror in limited quantities at the previously mentioned price. The product, however, will soon be launching a campaign in which Ilhan hopes to raise enough funds to bring the price down to $500.He also intends to donate the mirror to hospitals when it is financially possible to do so.

    It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.

    In recent years, many writers have begun to speak the 'decline of class' and 'classless society' in Britain. And in modern day consumer society everyone is considered to be middle class.

    But pronouncing the death of class is too early. A recent wide-ranging society of public opinion found 90 percent of people still placing themselves in particular class; 73 percent agreed that class was still a vital part of British society; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an important part of British society. Britain seems to have a love of stratification.

    One unchanging aspect of a British person's class position is accent. The words a person speaks tell her or his class. A study of British accents during 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice, Most people said this accent sounded 'educated' and 'soft'. The accents placed at the bottom in this study, on the other hand, were regional city accents. These accents were seen as 'common' and 'ugly'. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.

    In recent years, however, young upper middle-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song 'Common People' puts forward the view that though a middle-class person may 'want to live like common people' they can never appreciate the reality of a working-class life.

    Cli-Fi refers to "climate fiction"; it is a term invented by journalist Dan Bloom. These are fictional books that somehow or someway bring real climate change science to the reader. What is really interesting is that Cli-Fi books often present real science in a believable way. They become fun teaching tools. There are some really well known authors such as Paolo Bacigalupi and Margaret Atwood. A list of other candidate Cli-Fi novels was provided by Sarah Holding in the Guardian.

    What makes a Cli-Fi novel good? In my opinion, it has to have some real science in it. And it has to get the science right. Second, it has to be fun to read. When done correctly, Cli-Fi can connect people to their world; it can help us understand what future climate may be like, or what current climate effects are.

    One thing that is hard to imagine is the future. What will the world be like decades from now when Earth temperatures have continued to rise? What will agriculture be like? What will coastal communities be like? It is also hard to imagine what living a subsistence agriculture life is like, today. What happens to lives and communities when the rains change, or don't come at all? What would that world look like?

    One recent example of Cli-Fi literature is South Pole Station by Ashley Shelby. In this book we follow Cooper Gosling, who is traveling to a research location on Antarctica to create paintings. Yes, an artist is sent to live with researchers and crew ­ with funding from the National Science Foundation. After arriving at the South Pole, Cooper has to become acquainted with the strange social system that exists there. Ashley writes the book in such a way that you actually feel you are huddled(拥挤) in the cold with her and her co-workers.

    It is common to see many different kinds of insects while spending time outside in the summer. Some of them do not trouble people and can even add beauty to the natural environment. Other insects can harm the environment or humans. The population of these insects seems to stay large and healthy.

    But scientists say this does not appear to be true for some flying insects that serve an important purpose. There is growing evidence that these insects are decreasing across the world.

    One researcher looking into the present insect population is Doug Tallamy, a professor at the University of Delaware. He remembers walking through Washington D. C., in the past when it was "alive with insects, especially butterflies". Now, he said, "The flying insects are actually gone." Wilson said this point seemed to be proved during a drive he made last year from Boston to Vermont. He was surprised that, during his trip, he counted only one insect that had hit the car's front window. Several other scientists have carried out similar tests by checking how many insects hit their cars while traveling.

    While researchers admit this method is not scientific, they say it can still help them understand the changing flying insect population. There have not been many studies done on the flying insect populations covering large areas. However, some international research suggests a downward turn. In 2006, a group of studies showed that there had been a 14-percent drop in ladybugs(瓢虫) in the United States and Canada from 1987 to 2006. In Germany, a 2017 study found an 82-percent drop in the number of flying insects compared to levels recorded in 1990.

    After the German study, other countries also started looking into the problem. David Wagner of the University of Connecticut says other evidence leads him to believe the findings of the 2017 study are "clearly not a German thing".
