We have to be fit, no matter (不管) what age we are. It's very important for kids. That's w{#blank#}1{#/blank#} they have P.E. class.

    In Britain students have two hours of P.E. each week. P.E. includes sit-ups, press-ups (俯卧撑) and skipping rope.

    Students also p{#blank#}2{#/blank#}football, basketball and cross-country running. In summer kids run and do the high and long jumps.

    Most teens need more than 9 hours of sleep each night. But about 1 in 4 teens has trouble in sleeping. Lack of sleep can affect everything from our feelings to how well we focus on tasks like studying. It can also influence sports performance, increase our chances of getting sick, and may lead to weight gain in some people.

    How can we get the sleep we need? Here are some ideas:

    Be active during the day. Get at least 60 minutes of exercise a day. Physical activity can decrease stress and help people feel more relaxed. Just don't work too close to bedtime because exercise can wake you up before it slows you down.

    Say goodnight to electronics. Experts suggest using the bedroom for sleep only. At least shut everything down an hour or more before lights out.

    Keep a sleep routine. Going to bed at the same time every night helps the body expect sleep. Creating a bedtime routine can improve this relaxation effect. Reading, listening to music, spending time with a pet, writing a diary or doing anything else can relax you.

    Expect a good night's sleep. Instead of worrying that you won't sleep, remind yourself that you can. Say "Tonight, I will sleep well." several times during the day. It can also help to practise breathing exercises or gentle exercises before bed.

    Everyone has a sleepless night once in a while. But if you regularly have trouble in sleeping and you think it's affecting your mood or performance, talk to your doctor.

Imagine walking around a fashion store. You see a beautiful leather bag and want {#blank#}1{#/blank#} it. But in fact, it's made from recycled fruit and food waste. Would you still buy it?

Song Youyang, a 30-year-old material designer, works on developing products. She studied material design at a university in Germany and now lives in China. {#blank#}2{#/blank#} she was designing some new products, she couldn't find any suitable biomaterials (生物材料) to work with. So, she and her team decided to develop {#blank#}3{#/blank#} own new material from fruit waste.

The resulting material {#blank#}4{#/blank#} a lot like leather. It keeps the fruits' texture (质地), sense of touch and nice smell. Song and her team have used this new material to make fashion {#blank#}5{#/blank#} , such as bags, lamps and so on.

The designer thought these products would be {#blank#}6{#/blank#}. But in fact, not many customers have bought them. "Many people have their old ideas about biomaterials," said Song. "They think these materials are too expensive or of {#blank#}7{#/blank#} quality." As a result, it's quite difficult for these materials to become {#blank#}8{#/blank#} used. But Song still believes biomaterials will shape the {#blank#}9{#/blank#}. She and her team will {#blank#}10{#/blank#} working on new types of "green" materials and products.

Besides Song's team, many other fashion companies are {#blank#}11{#/blank#} working towards the same goal. They are showing us that fashion can be environmentally friendly.

Table manners

All societies have customs about how to eat politely. In English, we call these customs "table manners". Based on culture and location, table manners can be quite different from place to place. It's very interesting! {#blank#}1{#/blank#}

●In some cultures, it's polite to serve food to guests, while in other cultures, people don't do this because it makes the guests feel like they are being forced to eat.

●In most East Asian countries, people use chopsticks at the table. {#blank#}2{#/blank#} Do you know that in some places people simply use their hands to eat? And in some places, only their right hand?

●In Russia, it's polite to leave a bit of food on your plate to show the host that there was plenty to eat. {#blank#}3{#/blank#} It means you enjoyed the food.

{#blank#}4{#/blank#} So when you visit another place or another country, take the time to learn the local customs and manners. Remember, "When in Rome, do as the Romans do."
