Barcodes(条形码) aren’t given much thought by the majority of consumers, but these codes were fairly recently applied in a working fashion in 1970.

A small food store owner decided one day that keeping records of the inventory(存货) of his stock and the associated prices were an extremely laborious process, and so, in 1948, he contacted The Drexel Institute of Technology in a bid to work towards a solution. Bernard Sliver rose to the challenge and set out to study the problem and began working on a solution involving an automatic way of keeping track of items that had been sold. Sliver and a group of students from the institute realized their answer in the form of ultraviolet light (紫外线), ink and a scanner.

The system worked initially, but possessed some negatives. It was incredibly costly to carry out on a large scale and the system was also unstable. If the invention was to become commonplace（寻常的事）in grocery stores, these two problems had to be solved.

The patent (专利) for the bar code system was filed by Sliver and one of his students, Woodland. The patent was not granted immediately; in fact, it took three years for the patent agency to grant their invention patent for the barcode, occurring on 7^th October, 1952.

Despite the patent being issued, the system was still not welcomed by the majority of store owners. It was not until 1966 that the system began moving its way into more and more grocery stores. This system was soon criticized, as there was no central mechanism for controlling uniformly（统一地）coded items. In 1970, Logicom developed the Universal Grocery Products Identification code( UGOIC), soon shortened to Universal Identification Number (UPC). It was Marsh’s superstore, in Troy, which was the very first store to install this complex barcode reading system, and its popularity has soared(升温) ever since, and is obviously now commonplace in all types of stores worldwide.

1.What is stressed in the second paragraph?

A．The heavy work of store owners.

B．The function of ultraviolet light, ink and a scanner.

C．The origination of barcodes.

D．Bernard Sliver’s education background.

2.Which of the following was NOT a drawback of Sliver’s system?

A．It was expensive to be applied on a large scale.

B．It was a laborious process.

C．The system was not stable.

D．It lacked a central mechanism.

3.The popularity of the barcode rose quickly after________.

A．1948             B．1952             C．1966             D．1970

4.What is the purpose of the text?

A．To tell people that failure is the mother of success.

B．To praise scientists’ efforts in making people’s lives easier.

C．To describe shop owners’ opinions of barcodes.

D．To provide information about the development of barcodes.

Nature has its own way of balancing itself out, but when we humans get involved, we tend to throw things out of control. Forests and oceans are natural carbon sinks that absorb carbon dioxide from the atmosphere, but since we’ve been pumping too much into the air, those sinks can’t keep up. Scientists at the Max Planck Institute in Germany, led by biologist Tobias Erb, have figured out a way to supercharge plants to make them better at absorbing CO2, which could be a key defense against climate change.

Erb and his team figured out a way to make plants more efficient at absorbing carbon, so that they consumed more carbon in a shorter amount of time. “If you think about plants, they are efficient CO2-fixing filters, but they are not fast, ” Erb said. “I think there is a chance to improve existing biology with synthetic(人造的) biology.”

Erb’s team identified 17 enzymes(酶) from nine different organisms, re-engineering three of them, that had an enlarged carbon consumption. When those enzymes worked together as a team, they worked better at not only plants’ natural enzymes, but also themselves individually. Existing enzymes in plants consume about 5 to 10 molecules(摩尔) of CO2 per second. The team of enzymes that Erb used consumed 80 molecules per second.

So far, these enzymes have only been tested in test tubes in the lab, but the next step is real world testing where the enzymes would be introduced into plants to see if the same result occurs. If those tests show that plants really can be supercharged, we could have a new tool in the fight against climate change where not only do we protect the amazing carbon-absorbing forests we have, but we also add these super plants or an artificial leaf technology using the enzymes into other mixed fields.

1.Why can’t forests and oceans balance nature?

A. Because oceans and forests are getting smaller.

B. Because a large number of forests are cut down.

C. Because we human beings give off too much CO2.

D. Because there are too many creatures in the world.

2.Which is the key defense against climate change according to Erb and his team?

A. To increase the plants’ ability and efficiency to absorb CO2.

B. To make oceans and forests to absorb more CO2 quickly.

C. To reduce the human’s activities giving off too much CO2.

D. To increase the number of plants in the world.

3.What can we get from the last paragraph?

A. The enzymes have proved useful in real world.

B. The technology has worked against climate change.

C. The enzymes have not been used in the lab.

D. The technology may have a bright future.

4.This passage is intended to ________.

A. call on people to pay more attention to the balance of nature

B. introduce a possible way to better plants’ ability of absorbing CO2

C. analyze the cause and result of climate change related to plants

D. explore the possibility of using plants to fight against climate change

I was watching some little kids play soccer. These kids were only five or six years old, but they were playing a real game — a serious game — two teams, complete with coaches, uniforms, and parents. I didn’t know any of them, so I was able to enjoy the game without the distraction of being anxious about winning or losing.

The teams were pretty evenly matched. I will just call them Team One and Team Two. Nobody scored in the first period. Then came the second quarter. The Team One coach pulled out what must have been his first team and put in the scrubs(替补队员), except for his best player who now guarded the goal.

The game took a dramatic turn. I guess winning is important even when you’re five years old — because the Team Two coach left his best players in, and the Team One scrubs were no match for them. Team Two packed around the little guy who was now the Team One goalkeeper. He was an outstanding athlete, but he was no match for three or four who were also very good. Team Two began to score. The lone goalkeeper gave it everything he had, desperately throwing his body in front of incoming balls, trying bravely to stop them.

Team Two scored two goals in quick succession. It angered the young boy. He became a raging maniac — shouting, running, diving. With all the strength he could gather, he covered the boy who now had the ball, but that boy kicked it to another boy twenty feet away, and by the time he repositioned himself, it was too late — they scored a third goal.

I soon learned who the goalkeeper’s parents were. They were nice, decent-looking people. I could tell that his dad had just come from the office — he still had his suit and tie on. They yelled encouragement to their son. I became totally absorbed, watching the boy on the field and his parents on the sidelines.

After the third goal, the little kid changed. He didn’t quit, but he became quietly desperate and futility was written all over him. His father changed, too. He had been urging his son to try harder — yelling advice and encouragement. But then he became anxious. He tried to say that it was okay — to hang in there. He sorrowed for the pain his son was feeling.

After the fourth goal, I knew what was going to happen. The little boy fetched the ball from the net and handed it to the referee(裁判). He just stood there while huge tears rolled down both cheeks. He went to his knees, and he cried the tears of the helpless and brokenhearted.

At that moment, I saw the father start onto the field. His wife seized his arm and said, “Jim, don’t. You’ll embarrass him.” But he tore loose from her and ran onto the field. Suit, tie, dress shoe, and all — he charged onto the field, and he picked up his son so everybody would know that this was his boy, and he hugged him and held him and cried with him. I’ve never been so proud of a man in my life.

He carried him off the field, and when he got close to the sidelines I heard him say, “Scotty, I’m so proud of you. You were great out there. I want everybody to know that you are my son.”

“Daddy,” the boy sobbed. “I couldn’t stop them. I tried, Daddy, but they scored on me.”

“Scotty, it doesn’t matter how many times they scored on you. You’re my son, and I’m proud of you. I want you to go back there and finish the game. I know you want to quit, but you can’t. And, son, you’re going to get scored on again, but it doesn’t matter. In my eyes, you are the winner! Go on, now.”

The little guy ran back onto the field — and they scored two more times — but it was okay. Now in all viewers’ eyes, he is the Winner.

When you’re all alone, and you’re getting scored on — and you can’t stop them — it means a lot to know that it doesn’t matter to those who love you. In their eyes, so long as you don’t give up, you are the winner. And they are always proud of you.

D. He didn’t quit, but he became quietly desperate and futility was written all over him.
