What time of day can you think most quickly? Are you a morning person?" Or does it take you a few hours to get your brain going? A lot of recent research suggests that we should pay attention to our body clock. It can tell us what time of day we can perform best at.

    But everyone's body clock is different and some are special. Morning people will get up early and work better early in the day." Evening people will work later, but work better towards the end of the day.

    Research shows that we're better at some activities at certain times of the day." Physical performance is at its best between 3p. m. and 6p.- m.-,- so it's better to exercise later in the day.

    Between noon and'4p. m. , people begin to pay less attention. This is because we think less quickly after, a big meal. Research also shows we become sleepy around 2 p.m. This is why people in Spain take a short sleep in early afternoon.

    Finally'it is best to eat when we' re active. This allows our body to burn calories (卡路里) better and stops our blood sugar levels from getting too high.

    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.

    In England, people often talk about the weather because you can experience four seasons in one day. In the morning the weather is warm just like in spring. An hour 1 black clouds come, and then it rains hard. The weather gets 2 cold. In the late afternoon the sky will be clear, the sun will begin to shine and it will be summer at this time of a day.

    English playwright Arthur Wing Pinero said, "Where there's tea, there's hope." Similarly, a Chinese saying goes that "Firewood, rice, cooking oil, salt, sauce, vinegar and tea are the seven necessities to begin a day."

    Tea is, without doubt, welcomed all over the world. According to Statista, a German website for statistics (数据), global tea production reached about 5.8 million tons in 2018. It has become the most consumed beverage (饮品) in the world – after water, of course.

    According to the UN, tea is much more than just a hot drink. It's a big part of many cultures around the world. You probably know that people in China use top-grade tea to show respect when receiving important guests. Meanwhile, the British tradition of afternoon tea is an important part of that country's identity. Making Malaysia's pulled tea has become a sort of art form, where drinkers take pride in its entertainment aspects.

    Apart from its cultural significance (意义), tea is also a medicine, used from ancient times to modern day. "Tea is cold and lowers the fire," Chinese Ming Dynasty herbalist Li Shizhen once said. The health benefits of tea are still being discovered today: preventing heart disease, obesity and cancer have all been linked to drinking green tea, according to the National Center for Biotechnology Information in the US.

    Where were dominoes (多米诺骨牌) from? Modern dominoes first showed up in Italy during the 18th century. But it is believed that the earliest dominoes were Chinese playing cards. Italian missionaries (传教士) in China may have brought the game to Europe. Do you think so?

    Do you like to play with dominoes? Dominoes are small rectangular (长方形的) pieces made of wood or plastic (塑料). People can place dominoes in different shapes. Then, they push one domino down and the rest of the dominoes fall one by one. It is interesting to watch.

    But placing dominoes is hard. To make sure the dominoes fall smoothly, the space between each domino is important. According to domino—play. com, if a domino is about 4 cm long, then the space between two dominoes should be1—2 cm. If the space is too big, the dominoes will stop falling halfway. If the space is too small, the dominoes will fall too quickly and won't look interesting.

    Beginners can start by putting dominoes in a straight line. This is the easiest shape. Professional (专业的) players can place dominoes in many other shapes, including big circles, beautiful flowers and even famous paintings.
