After stepping into the classroom, I glanced round all the students and began my following words.“Thank you” is my  1  word, which I would like to use to express my deepest  2  to all of you.

Thinking back to the past 3 years, a lot of things  3 remain fresh in my memory.I cannot forget your  4  smile the first time I met you.I cannot forget that you were to 5  for your being late for class by the head teacher,   6  when I asked why you were late, you tried to  7  the fact of buying me a lovely teddy bear for Teacher's Day.I cannot forget your humorous words of breaking  8  when I was angry about your bad performance.I cannot forget that we share the happiness of success after making great   9

With time going by, I come to   10  that you are the mirror of my life.The mirror can reflect my past and  11  my future.Looking through the mirror, I'm more aware of my   12  and weaknesses.

It is you who made me believe love can be  13  .It is you who made me realize sometimes in the  14  of pursuing our dreams, we may  15  some difficulties and setbacks(挫折), but if we set up our mind to do it,   16  is impossible to a willing heart.

So standing in a higher position, I will help you to  17  the dreams confidently and firmly,   18  suffering the mistakes I made when I was your age.

19  , I pray that kind of friendship can stand the test of  20  and last forever.I pray that you can get good performance in the entrance examination and make your dreams come true.

Broken rubber bands and flat tires requiring replacement could soon be a thing of the past.

French researchers have developed a new kind of rubber that can repair itself when broken.The new rubber is made from widely available materials including vegetable oil and a common industrial chemical.All the materials are considered safe to the environment and can be easily reused.

The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch.When cut, the rubber can be made new again, simply by pressing the two broken ends back together.

The product can be repaired at room temperature, around twenty degrees Centigrade;other self-healing materials require higher temperatures for repair.

Traditionally, rubber substances are made from huge molecules(分子)connected by strong chemical links, or bonds.The new rubber is made of smaller molecules.The molecules are linked together using hydrogen bonds.When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks(超分子网).When the rubber is cut, the molecules attempt to connect with whatever molecule is near them.When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new.

However, time is an important element in the process.If the broken ends are not brought together quickly, a repair is not possible.This is because molecules will form bonds with molecules on their own side.The inventors say the surfaces of the rubber can be repaired within a week of being separated.

The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris.The organization is part of France's National Center for Scientific Research.The new material is described in greater detail in the research publication Nature

It was a beautiful Sunday morning, and Maggie and I were returning from our walk through the woods.We were only a couple of blocks from home when I spotted a cell phone and a credit card sitting on the road.We took them home.We always find amazing things on the street and she looks upon them as a movable feast-a chicken wing here or a barbecue rib (肋骨)there.

I found another cell phone a few years back, too, and called a number in its phone book.I explained the situation to the guy who answered.He said it was his sister's and that he'd come to pick it up, which he did.

And that was that.No verbal thank-you, no written thank-you, no “here's a box of chocolates” thank-you.

I didn't have time to call anyone on my latest found cell phone.I was pouring myself coffee when it started to shake and dance across the kitchen counter.

“Who's this?” someone asked when I picked up.

“Who's this?” I countered(反问).“Sarah?”

She was surprised at my knowing her name until she realized her name was on the credit card.“Could you send them to me?” she asked.

She lives in Arlington, which is 2 miles from my house.

“Hmm, no, ”I replied, adding that I thought she could come to get them, and that if I wasn't at home, they would be in my mailbox.

A day later, when I was out for a run, someone got them back.There wasn't even a piece of paper put in the mailbox with “Thanks” on it.In this age of e-mail and cell phone, there's really no excuse.Years ago, I found something more precious than a $100 bill on the street:a driver's license.I saw  that its owner lived a couple of blocks from me, so I called him up.He asked whether I could slip the license through his front door.

“I guess I could, ”I replied.

And that was that.
