If the butterfly doesn't struggle (挣扎；奋斗) to leave the chrysalis, it can't fly！The struggle develops the e{#blank#}3{#/blank#} in the butterfly which makes it fly. Similarly, the challenges of life bring out the best in young people and make the fly.

When people are young, meeting and overcoming challenges will make them s{#blank#}4{#/blank#} and ready to face life.

When we look at successful people, we see that the most successful of them are people who have had to struggle.

One famous businessman, who now o{#blank#}5{#/blank#}many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. He had to b{#blank#}6{#/blank#}up a big family. He took up the challenges and overcame them. Today his brothers and sisters are leading s{#blank#}7{#/blank#} lives.

Sometimes challenges do not appear to us because we keep away from them. So, some parents and teachers actively encourage young people to face challenges. They might organize some a{#blank#}8{#/blank#}for young people which provide them with challenges, like rock—climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of t{#blank#}9{#/blank#}. For countries to continue to become successful, it is i{#blank#}10{#/blank#}that the young people learn to meet challenges and overcome them.

    Maybe a lot of thin people will be worried about their health if the inside fat matters.

    Some doctors now think that the inside fat around important organs like the heart or liver could be as dangerous as the outside fat which can be noticed more easily.

    "Being thin doesn't surely mean you are not fat," said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have tested nearly 800 people with MRI to create "fat maps" showing where people store fat.

    According to the result, people who keep their weight through the food they usually eat rather than exercise are likely to have major deposits (堆积物) of inside fat, even if they are thin.

   Even people with normal Body Mass Index (体重指数) scores can have surprising levels of fat deposits inside. Of the women, as many as 45 per cent of those with normal BMI scores (20 to 25) actually had too high levels of inside fat. Men were nearly 60 per cent.

    According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the stomach first, but at some point, the body may start storing it elsewhere.

    Doctors are unsure about the exact dangers of inside fat, but some think it has something to do with heart disease and diabetes (糖尿病). They want to prove that inside fat does harm to the body's communication systems.

    The good news is that inside fat can be easily burned off through exercise or even by improving your eating habits. "If you want to be healthy, there is no other way. Exercise has to be an important part of your lifestyle," Bell said.

Every month, Zhang Lingling holds a party with her friends in a KTV room. At the party, all the people wear hanfu—a type of dress worn by the ancient Han people—and sing songs that are accompanied (伴奏) by traditional instruments or inspired by ancient poems.

"I'm really interested in clothes and songs based on traditional culture. I'm not buying the items just because they are Chinese—they just satisfy my aesthetic (审美的) needs," she told China Daily.

Like Zhang, there are many young people who have a passion for traditional Chinese culture. Looking for the reason behind this fascination with traditional culture, a professor Ji Fangfang said it's because traditional culture is the best way for young people to distinguish (区分) their national identity. They want to tell the world who they are. 

"Younger people know the world well through the Internet, and they need to express their uniqueness," Ji said.

While some prefer inheriting (传承) traditional Chinese culture, others are putting twists on it. Pop culture designer Yu Yang is one of them. When he made a series of products featuring the ancient God of Fortune, the god wore fashionable Chinese shoes and a cap, and had a microphone in his hand. "Pop culture is a universal language. I hoped more people would accept and love my work and know Chinese culture through my art pieces," he said in an interview.

Biomimicry borrows nature's design ideas and applies them to solve human difficulties. Nowadays a lot of companies started to invent in ways that are as elegant as what nature manages to do, and their designers and engineers began to sit with biologists to learn how nature would solve whatever it is they're trying to solve. 

 Some biologists worked with Nike company on apparel(服装）that would keep an athlete cool at the 2004 Summer Olympics. In a hot, dry place like Athens, what kind of organisms have to keep themselves cool and how do they do it? They found an African reed frog——a champion adapter in the heater—to study. 

If a company is making a solar cell , Biomimicry scientists will talk about how a leaf captures energy with their designers. Or if they're looking for some way to create an impact-resistant car, 

Biomimicry scientists will explain how woodpeckers can peck trees all day without harming themselves. 

Companies get the catalog of inspiration from the natural world and create things that sip energy, a city planner, an architect-should take one biology class in school. 

If you take a look at the octopus, you'll notice it moves fluidly and precisely but of course without motors or noisy fans or harmful fuel. The giraffe's vascular system allows it to pump blood up to its head and dip its head without getting dizzy. The humpback whale's flipper has scalloped edges to calm turbulence, and that's being mimicked in a new kind of wind turbine that can rotate in very low wind speeds because of its shape. There's even a new kind of pacemaker based on the heart of the whale. 

One famous biologist once said, 'In nature, failures are fossils. The organisms that are still with us are proven Companies that created a new product inspired by an organism have decided to donate a percentage of their proceeds to conserve the habitats of the organism. 

In ten years, you'll be able to visit ocean parks that have been preserved with the proceeds from a no-heat ceramic recipe based on the abalone's mother-of-pear!

Do you have a good time your family? Whether you do or not, these rules will help you.

1. ____

Most people value some privacy in their lives. If you expect your parents to knock before entering your room, you should do the same to remind them that it is important to do so.

2. Let parents know your plans

Whether your parents set some family rules for you or not, they want to be clear about your plans. If you go outlet them know when you'll comeback and who you're with. Doing this can avoid some parental worries.

3. Help with the housework

Everyone knows that the housework is far from fun, including your parents! But if you choose to help with the housework with or before being asked to do so, you will be in control of your own time, Of course, you are selective about what you do around the house. That means you can choose the housework that you prefer to do and avoid the housework you dislike most.

4. Be polite

There is an expression "a little goes along way" in English. It means that a small polite gesture can have a big influence. Most quarrels (争吵) can be avoided by talking with each other nicely.

5. Apologise

Sometimes, when quarrels happen, we just cant get along well with each other. However, there must besom cone who needs to calm down and apologise, Even if apology is just "I'm the sorry that I fought with you", it will work.

Children's Day is next Sunday, but Dong Fei is not happy. Her father is in Beijing. He is very busy and can not come back to Nanjing. Now, Dong Fei is in her room with Lin Min, her cousin. Dong Fei says,"I don't think I'm important(重要的) to my father. He is always busy with his work. Next Sunday is Children's Day. But he can not come back."

The telephone rings and Dong Fei goes to answer it. It's from her father." Feifei, can you come to the airport(机场) at 4:00 next Sunday afternoon? I can be there for only an hour. I have something for you."

" Yes, Daddy! Yes!" says Dong Fei.

After Dong Fei puts down the telephone, her cousin says," Well, I think your father really loves you. What about you? Do you love him?"

" Yes." says Dong Fei.

" Well, do you know it's Father's Day today?" Liu Min says.

" Oh, what? I'm so sorry." says Dong Fei.
