My students entered the art room with their usual eagerness to see what they would be learning in today's class. Little did they know they were going to be students for a new teaching method that is spreading the nation.

    I often use videos as previews and supplements (补充) to our art lessons providing students with a variety of artists showing their skills in real-life situations outside the classroom. Finding a new painting technique called glue batik(胶水蜡染),  I thought of something new I hadn't tried before!  How awesome would it be to learn a new technique together with artists? The lesson was planned, presented to the students without any introduction or set objectives. I also asked the students to watch and pause the video as often as they needed to.

    They watched as the artist explained and showed her skills, taking notes on her steps and results. After the video, they shared what they felt the artist's objectives were, her end result using art vocabulary as well as the steps they would need to know to present their own examples. Then they began creating their works using the glue batik technique.

    Surfing the Internet a couple of weeks later, I found that the teaching method I used sounded very familiar to a new movement in education called flipped teaching, which was developed by Jonathan Bergmann. He asked his students to watch video lectures at home and do exercises (homework) in class under supervision (监督). He found that grades went up and he also found time for other types of activities, which Bergmann states are more important than the videos.

    Back to my art class, the students were learning to get ideas, make predictions, and explain reasoning to their classmates. Together they compared, asked questions and made discoveries as they presented the technique.

    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 OxfordDictionary, 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.

    April 22nd every year marks the start of Earth Day, a day that is celebrated every year to raise awareness(意识)about our home planet and how we can save it from being damaged.

    Green up your home

    This is one of the most common things that people do whenever Earth Day rolls around, that is, switch off their lights.  Conserve (节约)energy by switching off all power of electricity points whenever they are not on use. In addition, take out all the plugs(插头) from plug points even after switching them off.

    Cars, being the greatest source of air pollution, can be left at home this weekend.  Other greener choices are carpooling, riding a bike or you can also walk if you want a healthier choice and if your workplace is not that far away from your home.

    Be a little dirty

    No, we don't mean it “that way”. We simply mean to say, don't take a bath. Yes, saving water is super important. A day or two without a bath won't harm you, but it will certainly do a lot of good for our planet. A daily shower isn't a matter of health; it's a matter of comfort.

    The future of our planet is in your hands!

A. Leave your cars at home.

B. Traveling by public transport is a better choice.

C. Below, we have made a list of things you can do to celebrate Earth Day.

D. Showering every day can wash away the natural oils that our skin and hair need.

E. However, this is not something you should do just for a day or for only an hour.

F. Started in the year 1970, Earth Day is now celebrated in more than 190 countries each year.

G. Do something every day that will improve your surroundings to make the planet a better place to live.

    Last weekend, there was art festival in our school. Our headmaster plan to make it a feature of our school. I was so excited, for it was the first time for me to join in it.

    Early in the morning, I saw such many people come to our school, made it so lively. The students gave a warm welcome to the guest. I walked around or appreciated the paintings. All of the works were from the students and I was very impressed by it. There were also some handcrafts, that were so creative. Though they were busy with their study most of the time, some students still managed to develop their hobbies. I should learn to them and develop a hobby as well as.
