A few years ago, I had the opportunity to play the character of Ronald McDonald for the McDonald's Corporation.
One day each month，we visited hospitals bringing a little happiness to the children there. But there were two rules placed on me during a visit. First, I could not go anywhere in the hospital  without permission. And second, I could not physically touch anyone within the hospital. They did not want me to carry germs(细菌)from one patient to another. Breaking either of these rules, I was told, I could lose my job. One day, as I was heading down a hallway and on my way home, I heard a little voice coming through a half­opened door，“Ronald，Ronald.”
I stepped in and saw a boy，about five years old, lying in his dad's arms, Mom with a nurse on the other side. I knew by the feeling in the room that the situation was grave. I asked his name. He told me it was Billy and that I did a few simple magic tricks for him. As I stepped back to say good­bye, he asked me “Ronald, would you hold me？”
At such a simple request, my heart was screaming, “Yes！”But my mind was screaming louder. “No！You are going to lose your job！”
“Hold me” was such a simple request, and yet I searched for any reasonable excuses that allowed me to leave, but none. It took me a moment to realize that in this situation, losing my job may not be the disaster I feared. Then, I picked up this little boy. He was so weak and so scared. We laughed and cried for 45 minutes. With tears in my eyes, I left them. Less than 48 hours later, I received a phone call from Billy's mom that Billy had passed away. She and her husband simply wanted to thank me for making a difference in their little boy's life.
Billy's mom told me shortly after I left the room. Billy looked at her and said, “Momma, I don't care any more if I see Santa this year because I was held by Ronald McDonald.”
For the record, McDonald's Corporation did find it out, but, given the situation，permitted me to go on with my job. I continued as Ronald for another year before leaving the corporation to share the story of Billy and how important it is to take risks.
【小题1】The underlined word “grave” in Paragraph 3 means “________”.

( B )
“Cool”is a word with many meanings．Its old meaning is used to express a temperature that is a little bit cold．As the world has changed，the word has had many different meaning．
“Cool”can be used to express feelings of interest in almost anything．
When you see a famous car in the street，maybe you will say，“It’s cool．”You may think“He’s so cool，”when you see your favourite footballer．
We all maximize（扩大） the meaning of“cool”．You can use it instead of many words such as “new” or “surprising”．Here’s an interesting story we can use to show the way the word is used．A teacher asked her students to write about the waterfall（瀑布）they had visited．On one student’s paper was Just the one sentence，“It’s so cool．Maybe he thought it was the best way to show what he saw and felt．
But the story also shows a scarcity（缺乏）of words．Without “cool”，some people have no words to show the same meaning．So it is quite important to keep some credibility（可信性）．Can you think of many other words that make your life as colourful as the word “cool”？ I can．And I think they are also very cool．
【小题1】We know that the word“cool”has had ________.

A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.
Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.
Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.
“No one had ever looked,” explained Randall Johnson, a biologist researcher.
Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.
“We have no reason to think that they are not in the skin of people too,” Johnson said.
These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.
These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.
Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.
The scientists detailed their findings in the April 18 issue of the journal Cell.
【小题1】Which of the following statements is TRUE according to the passage?

A MENTORING (导师制) program is giving life changing opportunities to Banbury youth.

Young Inspirations was founded two years ago to provide mentoring sessions for students and unemployed young adults aged 11 to 21.

Alex Goldberg, the program's founder, said; "We set up Young Inspirations because we wanted to give young people experiences which will potentially be life changing and broaden their outlook.

"We try to create work experience opportunities that will really make a difference to our youth. For example, we've secured internships (实习) with world-famous firms such as Honda.

"At a time of funding cutbacks where schools are finding it more and more difficult to offer this kind of mentoring, it is extremely important that these opportunities are available both to help youth with their school work and grades and to give them opportunities which may help shape their futures. " Kieran Hepburn, 14, is one of a group of Banbury youth who has benefited from the program so far. In October the Banbury School pupil was accompanied by Young Inspirations staff to Paris where he was an observer at the United Nations Educational, Scientific and Cultural Organization's (UNESCO) International Youth Forum (论坛).

The event was held for young people from around the world, to seek their views on how the future of youth and education should look. Kieran joined several hundred observers mostly in their 20s and was the only UK school pupil to attend the event. Kieran thinks the trip was a life changing experience. " Before we left I didn't quite know what to make of it but when we got there we didn't stop, it was amazing," he said, " We went to three or four hours of debates each day and then did something cultural each afternoon."

The main theme of the forum was how youth can drive change in political and public life. It dealt with issues such as drug abuse, violence and unemployment.

Kieran said: " It has really helped me to improve my confidence and social skills as well as my school grades and I was voted most improved pupil at school in August. "
