Have you seen the videos on TV? Do you wear large T-shirts and baggy（宽松的） jeans? Or have you heard someone rap (说唱)? Hip-Hop is very hot now.

Hip-Hop music was started in the middle of the 1970s by African Americans in New York. break-dancing (霹雳舞)and graffiti(涂鸦)are the two main kinds of music in Western Hip-Hop culture. Most of the Hip-Hop songs are about love, jobs or even games.

    Usually in rap, singers speak words very quickly to a certain beat. Most of the words are fun. Singers play off words to make fun of themselves or others. Hip-Hop music has few rules. Singers just do what they think and rap it out in a clever or creative way. The freedom makes a lot of teenagers fall in love with the music. Many of them like wearing large T-shirts and baggy jeans. Famous rap(说唱) and Hip-Hop stars include Eminem in the U. S. and Jay Chou from China.

    Today Hip-Hop is more and more popular across most of the world.

    You might think that native English speakers are the best at speaking the English language. But some experts believe that when it comes to successfully communicating in English, non-native English speakers are actually better at it.

    "Often you have a room full of people from different countries communicating in English and all understanding each other. And then suddenly the American or British person walks into the room and nobody can understand them," Chia Suan Chong, a UK-based communications culture expert, told the BBC.

    Chong said that happens because non-native speakers communicate more carefully. "English speakers, on the other hand, often talk too fast, use jokes, slang (俚语) and make references (引用材料) to their country that others might not understand," Chong said.

    It is something that I keep in mind when talking to my Chinese friends. I am careful to speak slowly and use words I know they will understand. Sometimes we confuse each other though. Once I told my friend "no dramas", which means "no problem". She thought I was calling her a drama queen, though, and got upset!

    But don't worry. Experts say that it is the native speaker's fault if they can't understand you, not yours! "English speakers with no other language often don't know how to speak English internationally," said English language teacher Dale.

    The best way to avoid any trouble might be to ask for some patience. If you find it difficult to understand an English speaker, don't be afraid to ask them to slow down and speak clearly.

    Did you spend much time lying on the comfortable sofa at home during the summer vacation? How often did you do sports this summer? People across the world need to get moving, according to a new study by the World Health Organization (世界卫生组织).

    5% of adults do not get enough exercise, according to the study. This number hasn't changed from 2001. Because of this, about 1.4 billion people are close to deadly diseases (疾病) such as heart disease and cancer (癌症).

    People should do at least 2 and a half hours of "moderate intensity (中等强度)" exercise each week, such as dancing or swimming. They can also do 75 minutes of "vigorous intensity (高强度)" exercise, such as running or playing soccer, according to the WHO.

    As for how to exercise more, experts says that we don't have to go to the gym (健身房) every time For example, we can go up and down stairs (楼梯) a lot instead of taking the lift. If we can't go to a dancing class each week, standing on one leg for 30 seconds a day is very good too.

    The study also found that women are less active than men, 32% of women hardly ever take exercise, compared to (比较) 23% of men. Women spend more time at home taking care of children and doing housework.

    But unlike that in most other countries, men are less active than women in China, with 16.6% of men and 12% of women not getting enough exercise.
