People who have lost the ability to understand or use words due to brain damage are called aphasics（失语症患者）.Such patients can be extremely good at something else.From the changing expressions on speakers' faces and the tones of their voices,they can tell lies from truths.

    Doctors studying the human brain have given a number of examples of this amazing power of aphasics.Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.

    Recently,scientists carried out tests to see if all that was said about aphasics was true.They studied a mixed group of people.Some were normal;others were aphasics.It was proved that the aphasics were far ahead of the normal people in recognizing false speeches—in most cases,the normal people were fooled by words,but the aphasics were not.

    Some years ago,Dr.Oliver Sacks wrote in his book about his experiences with aphasics.He mentioned a particular case in a hospital.Some aphasics were watching the president giving a speech on TV.Since the president had been an actor earlier,making a good speech was no problem for him.He was trying to put his feelings into every word of his speech.

    But his way of speaking had the opposite effect on the patients.They didn't seem to believe him.Instead,they burst into laughter.The aphasics knew that the president did not mean a word of what he was saying.He was lying!

    Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words.However,according to Dr.Sacks,they are more gifted than normal people.Normal people may get carried away by words.Aphasics seem to understand human expressions better,though they cannot understand words.

    If the crust (外壳) of the earth were not pretty solid (坚固的), it would be shaking about and moving up and down frequently. However, there are places in the rocks of the earth's crust where it isn't strongly held together—where faults exist. Along the faults, one rock might push against another with great force. The energy is changed to vibration in the rocks, so they begin to shake and we have an earthquake!

    The most famous one in North America was the San Francisco earthquake of 1906. Seven hundred people died and property (财产) damage amounted to about $425,000,000.The greatest destruction came from the fires that followed the quake.

    One of the most famous earthquakes in Europe took place in Lisbon, Portugal, in 1755. The city was destroyed and at least thirty thousand people were killed. In 1908, in Calabria and Sicily, a quake killed about seventy­five thousand people. In 1915, in central Italy, hundreds of towns and villages were damaged and thirty thousand people were killed.

    Two great earthquakes that caused great damage in Asia took place in Tokyo, Japan, and in Gansu Province in China. The Tokyo quake of 1923 killed more than one hundred thousand people and destroyed the city and the city of Yokohama, too. The Chinese quake in 1920 covered more than three hundred square miles and killed about two hundred thousand people.

    While both Europe and the United States of America are considered the Western world, it's good to know there are some differences in culture. If you are considering moving to a European country, you will find the information below helpful as you plan your move.

    One cultural difference is how the countries perceive（感知）time and space. For example, a house in the United States that is 200 years old would be considered ancient. This is probably because America is a fairly young country. However, in Europe, something would not be considered ancient unless it was at least 2,000 years old. However, perception of distance seems to be the opposite. While Europeans would consider 100 kilometers a long way to drive, Americans would think twice. This could be due to the fact that Europe is smaller and more heavily populated. In fact, the United States is over twice the size of Europe.

    Cars are another factor that differs greatly between Europe and the United States. American automobiles usually have automatic transmissions（传动）while European cars generally have manual gears（手动变速器）. European automobiles are smaller and more round-shaped, while American cars are larger and more square-shaped. Trucks and limousine are vehicles that American enjoy. In Europe, however, these types of vehicles are hardly seen, as they prefer smaller cars due to parking and traffic congestion.

    The view of education is another cultural difference between the European countries and the United States. In America, parents may save for many years and even go into debt to pay for their children to attend college. Most schools and universities in Europe, however, are free of tuition. In fact, it is just expected for children to attend college there and not a privilege（特权）, as in the United States.

    A project in Gambia is empowering women and reducing dangerous waste at the same time.

    The Waste Innovation Center, funded by the European Union's Global Climate Change Alliance, shows women in the Brikama area how to recycle waste into useful materials and products, which they can then sell in local markets.

    Wood-like waste is recycled into charcoal (木炭), for example, which can be used to supersede firewood and reduce the number of trees that are cut down for firewood. Food waste is recycled into compost(混合肥料)to function as environmentally friendly fertilizers and plastic is turned into many useful things.

    Supported by Waste Aid UK and the Gambia Women's Initiative (GWI), among others, the project provides women with skills they can use to become self-sufficient (自给自足的). Women learning at the center come from five communities, and some of them travel as far as 12 miles to learn these important skills that will provide them with an income, according to The Guardian.

    Isatou Ceesay, who now leads the GWI, highlighted the need to focus on economic equality in her country, telling The Guardian, "In terms of education, women are the ones who are always behind. Boys are chosen to go to school. When we conduct our training, we find women can do a lot, but don't know who they are, or how to carry out things. "

    According to the World Health Organization's Country Cooperation Strategy 2018—2023 report, the main environmental issue facing Gambia is poor waste management in urban areas. Ndey Sireng Bakurin, executive director of the National Environment Agency, has voiced concern over health and environmental risks, such as water pollution, the increase of insects as well as flooding that occur as a result of poor waste management.

    When the weather's hot, do you enjoy a glass of Brad's Drink while watching your TV made by Tokyo Telecommunications Engineering, and surfing the web using a search engine called BackRub? No? Neither do I. That's because all these companies have changed their names.

    Brad's Drink is now Pepsi. The mouthful that was Tokyo Telecommunications Engineering has become, simply, Sony. And BackRub is now known as Google. Though I must admit, the idea of a back massage does sound good right now!

    Joking aside, choosing the right name for your start-up is a serious matter. Think of the case of a small Canadian company called Research in Motion, who in 1998 had just developed a high-tech mobile phone that could send emails.

    They were torn between names like MegaMail and ProMail. Then they sought the help of consulting firm Lexicon, who specialize in brand names. They had other ideas. They brainstormed words connected to enjoyment and freshness. Someone said.

    Lexicon's boss added two capital letters, and there you have it: BlackBerry was born. Since then it has sold over 33 million handsets to customers around the world. Would it have sold as well if it was called MegaMail? Who knows?

    Recently, BlackBerry sales have been overtaken by Android phones and Apple's iPhone. Lexicon's founder David Placek is a big fan of simple brand names like those Apple chooses: the iPhone. They l0ok a household word and by putting one letter in front of it, it ends up being game changing.

    So, for all you entrepreneurs(企业家)out there, make sure you allow time to develop a catchy and memorable name. Think about what makes your company different. What's your USP (独特的销售主张)? Maybe you can reflect that in your name.

    What about you? What would you call a company if you had one?

Three grade 11 students from Harbour View High School, Canada, wanted to convey their message of fighting climate change to a younger audience. So, they wrote a children's book named Keeping It Cool as part of a project.

Upon receiving their first order of 12 copies, Claire Malco, the illustrator of the book, vividly recalls the moment when the realization struck. "I just sat there with my mouth open and was like, wow, this is actually happening," Malco told CBC News.

Coauthored by Joanna Jackson and Olivia Jordan, the book employs age-appropriate analogies (类比), coupled with vibrant illustrations, to promote actions kids can take against climate change. To explain the concept of the atmosphere, for example, the young authors drew a bubble(气泡) around Earth throughout the story. They also call for actions, such as planting trees and vegetable gardens – explaining how plants absorb CO2 from the "bubble" atmosphere just like a vacuum cleaner (真空吸尘器). The book also tells kids how they can avoid polluting the bubble by trying to walk, bike or scoot instead of taking a car or bus.

"The entire second half of the book is just things kids can do without needing their parents' support … We wanted it to be something that every kid could finish," Jordan explained to CBC News.

On Earth Day, the students visited a local elementary school where they read their stories and facilitated discussions about the text with every grade 5 class. They spread awareness that, regardless of age, anybody can help make a positive impact on Earth's climate."Educating students was the intention when writing this book. Having the opportunity to present to 10 different classes helped us gain insight on how to better our presentation and content, as well as see the impact this book will have on students," the students told Our Canada Project.
