Whenever I'm invited to somebody's house for the first time, I'll take a close look at their bookshelves. What they keep on their shelves, in my eyes, is a reflection(反映) of their personal tastes and interests. The books on a bookshelf tell the story of a life.

My own shelves are a kind of road map through my life, telling a chronological tale. First up come my favorite childhood reads, like Water ship Down and His Dark Materials. The collection then moves on to teenage things I read in school — Nineteen Eighty-Four, The Handmaid's Tale and A Clockwork Orange. Finally, we come out of full-time education and enter the real world, and this part is a reflection of my professional( 职业的) life, from the first exciting days of their work experience to the present.

If you pointed to any book on my shelves, I could name the year I got it, where I was working, and probably where I was living at the time.

▲ It is an easy way to get to know about his hopes, dreams and interests. And a big part of that story is how we arrange our books, and get on with them. It's such a personal thing, different from each other. Some want to be with their books in every room, others have them on shelves, behind glass or simply lining their floors. Each home has a story to tell through the way they live with their books.

It's often said that what we read says something about who we are. The way we fill our bookshelves might also send a message about ourselves. From the pile of books on your bedside table to your well-organized shelves, whether we notice it or not, our book collections are telling a story before a single page has been turned.

Mobile phones are becoming more and more popular not only with adults but also with students. However, they also have become a problem for middle schools in the last few years.

Some children have got mobile phones as Christmas or birthday gifts, and more will ask their parents to buy phones for them.

Many students like mobile phones because they are easy and quick. Some parents feel it convenient because they can get in touch with their children. Some teachers think using mobile phones is a distraction(分心的事)to students during school hours and mobile phones also give them much trouble in their classrooms. Sometimes students send phone messages to cheat(作弊)during exams. A new study says that some teenagers even hurt their fingers because of the over-use of mobile phones. They keep using mobile phones for more than ten hours during a day.

Many teachers suggest that students should not have phones at school, but if there is a good reason, they can leave their phones at the school office. Many people think they understand why parents would want their children to have them, but they agree school should let the students know when they can use their mobile phones.

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!

When I was in the seventh grade，I always liked to eat or listen to music in class while I was doing homework. This bad habit 1 my poor grades directly. My mother was worried about my study. So she found my head teacher Susan and asked her to be2 with me. 

I thought my head teacher would3 me. At that time，I was very worried until one day my head teacher asked me to go to the playground to meet her. I4 rushed to the playground though I was afraid. 

5 I ran to my head teacher，she gave me a stick. She asked me to draw a circle on the ground with my left 6 and a triangle with the other one at the same time. Then I began to draw circles and triangles with both hands. I7 many times but I failed. 

Half an hour later，my head teacher smiled and said to me， "In fact，almost 8 can draw a circle and a triangle at the same time. After all，our energy is not enough to finish many 9 at the same time. We must pay attention to one thing to succeed. " From then on，I began 10 my heart to my study. Since then，I have made rapid progress.

Elias Chasiotis loves taking photos. He s{#blank#}1{#/blank#} a few days in Qatar. That was surely a worthy trip. One day, a solar eclipse（日食） was in progress above the sea, making it look like two horns rising from the water. And Chasiotis caught it all with his c{#blank#}2{#/blank#}. 

The photo wasn't the result of just chance and luck. Chasiotis carefully chose a place where he got a perfect view of the eclipse. The w{#blank#}3{#/blank#} wasn't good at the beginning— it was cloudy. He was w{#blank#}4{#/blank#} that he couldn't see anything. L{#blank#}5{#/blank#}, the Sun began to rise after a while. It looked like two red horns rising from the sea. Because of their shape, they were nicknamed the "Devil's Horns".
