A sunflower is a sunflower . A mobile phone is a mobile phone . But can you combine the two to do something for your local environment?
As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower. A biodegradable (能进行生物递降分解的) mobile phone was, this month, introduced by scientists.
Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms nitrates (硝酸钾). These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. "We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.
As phone technology is developing so quickly people are constantly  throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. "The seed is released and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it," said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.

The story happened on a hot heavy rainy day.
After class, I took a few bottles to go and   36  some water from the water room. Oh! There were so many people! I had to wait   37  the rain. My hair didn't get wet because I wore a hat, but my clothes  38  .
When at last it was my   39  , I filled the bottles as quickly as possible. I began making my way back when I saw a boy   40  towards me. He   41  two umbrellas in his hand. He shouted hello and as he came   42  , I recognized that it was Tom.
He   43  my classmate for nearly three years, but we never   44  more than ten sentences. He was silent, but I liked talking. We were quite   45  people and had nothing in common. I didn't   46  him and even didn't want to see him.
"Hey! What's wrong?" His words   47  me out of my thought. "I saw you   48  in the rain, so I brought you this umbrella. But it seems a little   49  , your clothes are already wet,"
On hearing this, I was so   50  that I couldn't say a single word.
"Don't just stand there. Let's go!" He said and held the umbrella for me. We walked towards   51  and this time we talked   52  .
"I know you don't like me, but I want to   53  with you." he said, "You may think I am silent, but it is because I can't find the right   54  to say."
The rain finally stopped and we saw a rainbow in the blue sky. I said to myself, "It is wrong to  55 someone only by his appearance.

On the first day of my new high school, I almost had a nervous breakdown. Everything about the school seemed so difficult. When I got home, my parents said, “You're nervous and that's okay. Everyone is afraid of high school. ”I denied it. I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends.
On the first day I was late for every class and was constantly lost. The school seemed like a puzzle that I couldn't figure out. Was this how the whole year was going to be？ I didn't think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it！The schoolmates seemed to regard me as a fool, and they were probably right.
Despite my fears, after the first week I finally had my schedule figured out.
With the exception of falling up and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad.  It was actually much better than middle school and much more challenging.
Since then, I've been elected vice president of my class, which wasn't much of a victory since only three people ran for the four positions.
It is normal to be scared about a new school. Take a deep breath and relax. High school is something that any student can overcome. Make sure you participate in some out-of-class activities because you’ll find it easier to make friends. Try to do your best, even if it isn't straight A’s.
Most important of all, be who you are , whether you're a “fool”, an athlete, or a lower grader. Don't try to pretend to be someone you're not. Now you know the true secrets of high school.
