Most students, when asked about their ideal graduation gift, would probably reply, “A car”, or “Money for a deposit on a house”. Cai Kaiyuan, 21, made a different choice. As a graduation gift to himself, he decided to work as a volunteer teacher in a remote village in Tibet.
Cai, a senior majoring in electrical engineering at Huan Railway Professional Technology College, originally planned to cycle from Sichuan to Tibet. During his journey, Cai’s idea for a different graduation gift to himself began to take shape. “I did not know beforehand what the journey would mean to me. I just want to gain a unique experience and have pleasure in appreciating the view there,” he said.
It turned out cycling on a plateau was extremely challenging. And it has kept changing his outlook on life. Cai’s fingers even became frostbitten while cycling up a 5008-meter-high mountain, where temperatures often dropped to 18 below zero. At night, the ice covered the road and he fell off his bike three times. The lack of oxygen made him feel dizzy and weak. “At the most serious moment, I felt that my life was on the line,” said Cai.
However, he also gained something unexpected. At Ya’an, a city in Sichuan, he met a group of tourists who are also university students. A girl called Wu Ling told him that she planned to work as a teacher in a primary school in Tibet after her journey. He was impressed by the idea as she looked slender and weak.
It was not until he reached a family-run hotel in Shigatse that Cai’s spirits began to rise. The hotel manager’s two daughters enjoyed talking with him. The kids asked about his experiences on his trip, and showed him the beautiful local lakes. “They told me that they always liked to talk to guests, as they wanted to improve their Mandarin,” he said, “Their parents and many locals can only speak Tibetan.”
Cai was touched by the girls’ story. Their situation is tough and the local people have little chance to learn Mandarin because the schools are short of teachers. “I want to do something to improve the situation for kids like them,” said Cai. His parents finally gave their agreement and his teachers also supported him.According to the passage, Cai Kaiyuan’s graduation gift to himself is _________.
| A．to have money for a deposit on a house |

Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88°C and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05°C. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules (分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.Why can the Antarctic cod live at the freezing temperature?
A. The seawater has a temperature of -1.88°C.
B. It loves to live in the ice-salt mixture
C. A special protein keeps it from freezing.
D. Its blood has a temperature lower than -2.05°C.What does the underlined word “it” in Paragraph 5 refer to?
| A．A type of ice-salt mixture. |
| B．A newly found protein. |
| C．Fish blood. |
| D．Sugar molecule. |
What does “glyco-” in the underlined word “glycoprotein” in the last paragraph mean?
| A．sugar | B．ice | C．blood | D．molecule |
What is the best title of this passage?
| A．Discovery of the AFGP. |
| B．A special fish living in Antarctica. |
| C．The ice shelf around Antarctica. |
| D．Protection of the Antarctic cod. |
If you were to walk up to Arthur Bonner and say, “Hey, Butterfly Man,” his face would break into a smile. The title suits him. And he loves it.
Arthur Bonner works with the Palos Verdes blue butterfly, once thought to have died out. Today the butterfly is coming back — thanks to him. But years ago if you’d told him this was what he’d be doing someday, he would have laughed, “You’re crazy.” As a boy, he used to be “a little tough guy on the streets”. At age thirteen, he was caught by police for stealing. At eighteen, he landed in prison for shooting a man.
“I knew it had hurt my mom,” Bonner said after he got out of prison. “So I told myself I would not put my mom through that pain again.”
One day he met Professor Mattoni, who was working to rebuild the habitat (栖息地) for an endangered butterfly called El Segundo blue.
“I saw the sign ‘Butterfly Habitat’ and asked, ‘How can you have a habitat when the butterflies can just fly away?’” Bonner recalls. “Dr. Mattoni laughed and handed me a magnifying glass (放大镜), ‘Look at the leaves.’ I could see all these caterpillars (蝴蝶的幼虫) on the plant. Dr Mattoni explained, ‘Without the plant, there are no butterflies.’”
Weeks later, Bonner received a call from Dr. Mattoni, who told him there was a butterfly that needed help. That was how he met the Palos Verdes blue. Since then he’s been working for four years to help bring the butterfly back. He grows astragalus, the only plant the butterfly eats. He collects butterflies and brings them into a lab to lay eggs. Then he puts new butterflies into the habitat.
The butterfly’s population, once almost zero, is now up to 900. For their work, Bonner and Dr. Mattoni received lots of awards. But for Bonner, he earned something more: he turned his life around.
For six years now Bonner has kept his promise to stay out of prison. While he’s bringing back the Palos Verdes blue, the butterfly has helped bring him back, too.When he was young, Arthur Bonner ___.
| A．broke the law and ended up in prison |
| B．was fond of shooting and hurt his mom |
| C．often laughed at people on the streets |
| D．often caught butterflies and took them home |
Bonner came to know the Palos Verdes blue after he ___.
| A．found the butterfly had died out |
| B．won many prizes from his professor |
| C．met Dr. Mattoni, a professor of biology |
| D．collected butterflies and put them into a lab |
From the last sentence of the text, we learn that raising butterflies has ___.
| A．made Bonner famous | B．changed Bonner’s life |
| C．brought Bonner wealth | D．enriched Bonner’s knowledge |
Which of the following would be the best title for the text?
| A．A Promise to Mom | B．A Man Saved by Butterflies |
| C．A Story of Butterflies | D．A Job Offered by Dr. Mattoni |
Nuclear energy has always been controversial. But since the tsunami and nuclear disaster in Fukushima (Japan) last year the issue is back in the headlines. And the world is divided— some countries are planning more nuclear plants, while others have promised to shut theirs down.
After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy are also phasing out nuclear power. But France and the United States remain staunch supporters of atomic energy. In fact, almost 80% of France’s electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it “continues to support the expansion of nuclear power, despite the crisis in Japan.”
Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power doesn’t create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain’s chief scientific adviser (John Beddington) supports this view. He recently said that the world doesn’t have the luxury of ignoring nuclear energy.
Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they’re expensive; and right now, they require a lot of investment. This higher cost of using “green energy” is usually passed onto the consumer. So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills. This is of particular concern while the world economy is in such bad shape.
The main argument against nuclear energy is that it isn’t safe. For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands.
The nuclear energy issue is very complex. And it doesn’t look like it’ll be resolved anytime soon. As a Japanese commentator recently said, “it’s been a bad year for the ‘nuclear village’, but I don’t think they’re down and out yet.” The battle continues.Which of the following may NOT be the advantage of nuclear energy over other energy sources?
| A．Nuclear energy doesn’t produce any greenhouse gases. |
| B．Nuclear energy can help prevent the climate damage. |
| C．Nuclear energy is more environmental-friendly than other green energy sources. |
| D．Nuclear energy can save the consumers some money, compared to other renewable energies. |
What does the underlined word “this ” refer to in paragraph 4?
| A．The fact that many people prefer to use the green energy sources while unwilling to pay higher bill. |
| B．The cost of using renewable sources |
| C．The fact that the nuclear power is cheaper. |
| D．The investment of renewable energy sources |

| A．convince the reader that nuclear waste is difficult to get rid of. |
| B．explain that nuclear waste may remain harmful to humans for thousands of years. |
| C．persuade the world not to use nuclear energy. |
| D．support the idea that nuclear energy is not safe. |

One evening I was on my daily evening return from London to my home. I had got into the habit of sitting in the last carriage at the platform, so I could get off near to the station exit at my end. One evening before getting off the train, I found a purse. I opened the purse and thought this must be my lucky day, for the purse contained some ￡80 in cash. Looking further into the purse, I found credit cards, and house keys and a name and address. My first thought when seeing the cash was to pocket it, and throw the other contents away.
Now I am not a basically dishonest person, but had developed a hardened attitude over the years that most people were dishonest in some way, and my own personal experience had been that whenever I lost anything of value, that was the last I ever saw of it. And since I was a construction worker at that time, I had been the victim of a great deal of stealing during my working life.
Almost as I read the name and address, I had a picture of that woman being struck with terror, when she realized she had lost her purse, and could not get into her home, had no money, and, would have thoughts of someone spending on her credit cards, not to mention the trouble of canceling all the cards.
In that same moment I decided to hand the purse over to the train guard. So I told him I would like to see it returned to its rightful owner. He told me would be sent to the lost property office. I arrived at my station and started to walk the five minute journey to my home all the while feeling very pleased with myself that I was going to bring a great deal of happiness to someone I did not know.The author liked to sit in the last carriage because ________.
| A．sitting in the last carriage was safer |
| B．he was always almost late for his train |
| C．he could get out of the station sooner after getting off |

| B．The author thinks not all the people are honest all the time. |
| C．The author often lost things in the past. |
| D．The author always got his lost things of great value back. |
