We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.

The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a $10,000 prize, a $20,000 scholarship, and a chance to revolutionize a major environmental issue.

Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.

With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.

The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.

“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.

Daniel Burd won first prize at the Canada Wide Science Fair because      .

    A. he found a new kind of microorganism

    B. he contributed much to environmental protection

    C. he found a way to degrade plastics in shorter time

    D. he could encourage microbe growth in an easier way

Daniel Burd exposed one plastic sample to dead bacteria to      .

    A. make the live bacteria work better      B. test how effective his method was

C. know which bacteria worked faster      D. control the temperature in the process

Maintaining the required temperature takes little energy because       .

    A. plastics can get hot easily           B. microbes can produce heat themselves

    C. much carbon dioxide is produced     D. the temperature can be controlled

Daniel Burd got his idea from       .

    A. his school textbook          B. the failure of researchers

    C. his everyday work           D. the practice of other people

It had been some time since Jack had seen the old man. College, carrier, and life itself got in the way. In fact, Jack moved clear across the country in pursuit of the dreams. There, in the rush of his busy life, Jack had little time to think about the past and often no time to spend with his wife and son. He was working on his future, and nothing could stop him.

Over the phone, his mother told him, “Mr. Belser died last night. The funeral is Wednesday.” Memories fleshed through his mind like an old newsreel as he sat quietly remembering his childhood days.

“Jack, did you hear me?”

“Oh, sorry, Mom. Yes, I heard you. it’s been so long since I thought of him. I’m sorry, but I honestly thought he died years ago,” Jack said.

“Well, he didn’t forget you. Every time I saw him he’d ask how you were doing. He’d reminisce (回忆) about the many days you spent over ‘his side of the fence’ as he put it, ” Mom told him.

“I loved that old house he lived in,” Jack said.

“You know, Jack, after your father died, Mr. Belser stepped in to make sure you had a man’s influence in your life,” she said.

“He’s the one who taught me carpentry. I wouldn’t be in this business if it weren’t for him. He spent a lot of time teaching me things he thought were important. Mom, I’ll be there for the funeral.” Jack said.

Busy as he was, he kept his word. Jack caught the next flight to his hometown. Mr. Belser’s funeral was small and uneventful. He had no children of his own, and most of his relatives had passed away.

The night before he had to return home, Jack and his Mom stopped by to see the old house next door one more time, which was exactly as he remembered. Every step held memories. Every picture, every piece of furniture … Jack stopped suddenly.

“What’s wrong, Jack?” his Mom asked.

“The box is gone,” he said.

“What box?” Mom asked.

“There was a small gold box that he kept locked on top of his desk. I must have asked him a thousand times what was inside. All he’d ever tell me was ‘the thing I value most’,” Jack said.

It was gone. Everything about the house was exactly how Jack remembered it, except for the box. He figured someone from the Belser family had taken it.

“Now I’ll never know what was so valuable to him,” Jack said sadly.

Returning to his office the next day, he found a package on his desk. The return address caught his attention.

“Mr. Harold Belser” it read.

Jack tore open the package. There inside was the gold box and an envelope. Jack’s hands shook as he read the note inside,

“Upon my death, please forward this box and its contents to Jack Bernett. It’s the thing I valued most in my life.” A small key was taped to the letter. His heart racing, and tears filling his eyes. Jack carefully unlocked the box. There inside he found a beautiful gold pocket watch. Running his fingers slowly over the fine cover, he opened it.

Inside he found these words carved: “Jack. Thanks for your time! Harold Belser.”

“Oh. My God! This is the thing he valued most …”

Jack held the watch for a few minutes, then called his assistant and cleared his appointments for the next two days. “Why?” his assistant asked.

“I need some time to spend with my son,” he said.

Why did Jack think Mr. Belser died years ago?

   A. College and career prevented him from remembering Mr. Belser.

   A. Because he was grateful for Jack’s time with him.

   B. Because he had no children or relatives.

   C. Because he thought he had to keep his word.

   D. Because Jack had always wanted it during his childhood.

   B. He had promised to spare more time to stay with his son.
