    I am Peter Hodes, a volunteer stem courier. Since March 2012, I've done 89 trips of those, 51 have been abroad, I have 42 hours to carry stem cells(干细胞) in my little box because I've got two ice packs and that's how long they last, in all, from the time the stem cells are harvested from a donor(捐献者) to the time they can be implanted in the patient, we've got 72 hours at most, So I am always conscious of time.

    I had one trip last year where I was caught by a hurricane in America. I picked up the stem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London. But when I arrived at the check-in desk at Providence, the lady on the desk said: “Well, I'm really sorry, I've got some bad news for you-there are no fights from Washington.” So I took my box and put it on the desk and I said: “In this box are some stem cells that are urgently needed for a patient-please, please, you've got to get me back to the United Kingdom.” She just dropped everything. She arranged for a flight on a small plane to be held for mere-routed(改道) me through Newark and got me back to the UK even earlier than originally scheduled.

    For this courier job, you're consciously aware than that box you're got something that is potentially going to save somebody's life.

    You may hear about some people who have walked on the moon. Of the outstanding astronauts listed below, who do you think was the most influential in human's history?

Pete Conrad (Apollo 12)

    Because of his dyslexia（阅读障碍）, Pete always failed in his study and had to leave school. Then his father sent him to Darrow School, where he performed so well that he won a Naval Reserve Officers Training Corps (NROTC) scholarship. He took the NASA's test, but his dyslexia ruined the opportunity.

    It was because of Alan Shepard's persuasion that Pete decided to apply again for NASA. He was chosen as the commander of Apollo 12. He landed on the moon on Nov 19, 1969 and spent 31 hours there.

Neil Armstrong (Apollo 11)

    Armstrong's biggest moment came in 1969, when he was chosen for NASA's first manned lunar mission (登月任务), along with Edwin Aldrin and Michael Collins. On July 21, 1969, he set foot on the surface of the moon. which made him the first human to do so. He stayed on the moon for 21 hours. After returning, Armstrong became an international star and was honored worldwide.

John Young (Apollo 16)

    Young was made the commander of Apollo 16, which landed on the moon on April 16, 1972. He spent two days and 23 hours on the moon. Young retired from NASA after serving for around 42 years, which made him the man ever to work for NASA for the longest time.

Edgar Mitchell(Apollo 14)

    Edgar was selected by NASA in 1966, and was later made the lunar pilot of Apollo 14. He followed his commander Alan Shepard onto the moon, staying there for 1 day and 9 hours. Edgar has expressed his firm belief that UFOS belong to other planets. He also firmly believes that American government is in possession of some “recovered alien bodies.”

    Last week the British university system offered a record number of places. That sounds like good news—but do we really need more people to go to university? For that matter, does the world need more universities?

    The answer feels like it should be yes.

    Education is good, is it not? But everything has a cost.

    Education takes time. We could insist that everyone study full-time until the age of 45 but that would surely be too much. And perhaps half the population studying until they're 21 is also too much. As for universities, they consume financial and intellectual resources—perhaps those resources might be better spent elsewhere.

    My own personal opinion is strongly in favor both of going to university, and of simply having universities around.

    The main skill I learnt at university was to write about economics, and I use that skill every day of my professional life, even an abstract education seems practical to me. And I now live in Oxford, one of the world's most celebrated (著名的) university cities. Oxford's experience certainly suggests that universities have much to offer.

    The city's architecture and green spaces have been shaped—greatly for the better, on balance —by the 900-year-old institution at its heart. The beauty attracts tourists and locals too.

    But these are samples of one. Many people do not find themselves using the skills and knowledge they accumulated at university. And Oxford's dreaming spires (尖顶) aren't terribly representative of global universities as a whole.

    "Our aim is to take our art to the world and make people understand what it is to move," said David Belle, the founder of parkour.

    Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.

    Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the barriers in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.

    Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.

    Overcoming all the obstacles on the course and in life is part of the philosophy behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back in your life, to reach the destination successfully. A parkour lover said, "I love parkour because its philosophy has become my life, my way to do everything."

    Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself.

    Grandma Pugh sized up the baby like a pig at the farmers' market. There was a pause and then she pronounced. "He's got nice long legs." She clapped her hands once in approval. But then she frowned and leaned forward. Everyone waited anxiously. The baby had opened his eyes and was staring up. "But those cross eyes won't do," she declared firmly, shaking her head in disappointment.

    That had been Freddie Pilcher's first meeting with Grandma Pugh. Since then, ten years had passed. Much to his grandmother's satisfaction, she'd been proven right about the boy's legs. He was a regular beanpole. Grandma Pugh had also been correct about his eyes. Freddie had been wearing glasses to correct his vision since he was two years old. His current pair was thick, and cheap-looking, but at least he could see.

    Freddie not only had poor eyesight, but he was also clumsy. He wasn't good at schoolwork either. But there was one thing that the boy was good at and it was all on account of the length of his legs. He could jump.

    Freddie was the best jumper in school. Not only could he leap the furthest but also the highest. At break times, he entertained the little ones by leaping over the school wall into Mrs. Hobson's garden and then rapidly jumping back. She had been up to see the head teacher several times because somebody had been crushing her vegetables.

    It was badgers (獾), Freddie suggested, when questioned by Miss Harpy—definitely badgers; no doubt about it. His dad had terrible problems with badgers. Only last week he had lost two rows of carrots. Freddie had woken one night and heard them tearing through the garden, a whole herd of them. They rooted up the lawn and dug up the vegetables. Terrible things, badgers. All the other children nodded their heads wisely. There was a moment's pause in Class Three as everyone thought about the dreadful damage that badgers could do.
