Last week I was riding my special motorbike and then stopped at a convenience store.As I was getting my wheelchair off the back,a man watched me from his car and I noticed a wheelchair in his back seat.We spoke for a moment and I asked him about the wheelchair.He answered that it was for his daughter.“Well,do you think she would like to go for a ride on my motorbike with me?”I asked.He seemed shocked that a total stranger would ask him this.He thought about it for a second and said,“OK,as long as I can follow you.”

    He introduced me to Amy and he sat her on my back seat.Her father followed me for a few miles and she talked non-stop about what she wanted for Christmas.

    As we came back to the convenience store,she said,“This ride is the best Christmas present I could ever receive. I have been in a wheelchair my whole life and didn't know I could do this.”I told her about some of the other things I do (ski,travel the world by myself,etc.).As her father was taking her off my bike,she turned to him and said,“Oh Daddy,I'm going to be OK.Mr.Bryant does all kinds of things,and I win too.” Her father turned away as a tear of joy rolled down his cheek.He hugged me and said,“I was sitting here praying for a gift for Amy that would encourage her.She often felt that her life was dull compared to other children.God answered my prayer just now.Now I pray that God will bless you for your gift to Amy today.” I believed what he said.Being kind and thoughtful to others,we can be an answer to prayer.

    With the start of the new term, the students around the country exchange their fun and fashionable clothes for boring school uniforms. But not all schools are fashion deserts. Colorful sports shoes, school bags, T-shirts and even drink containers are breathing life into campuses.

    "The uniform makes us look like a bunch of clones, especially when we are doing morning exercises on the playground," said Qing Pei, a Senior 2 from Shanghai Qibao High School. "But the boys wear different sports shoes and girls have different decorations in their hair. These are the areas where you can express yourself," said Qing.

    Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.

    "Nike and Adidas basketball shoes, although they are still the must-have items for many of my friends, are becoming out-of-date," Qing added. He explained that "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn."

    "Still in fashion are the various baseball caps and American-style T-shirts with random (随意的) English words printed on them," said Qing. "The accuracy of the written message is not important. Often, the words are misspelt. Sometimes they do not even make sense, "Qing said with a smile.

    Besides sports shoes and T-shirts, styles and colors of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls.

    Other fashionable items are the colorful drink containers which are now popular among girls this term.

    "Some teachers are surprised to see a teenager sucking a bottle like this at school and criticize it as a childish regression (退化). But some girls just love it," said Yang Rui, a Senior 3. from High School attached to Xi'an Jiaotong University.

    There once lived in China a very foolish king and queen. One day the queen had a baby daughter. When they saw their baby, they both cried out, “My goodness! How small it is! It's hairless and toothless! It's a monster!” they sent for all the doctors in the country and ordered them to prepare some medicine for her.

    “When she drinks your medicine, she must grow to the right size and have hair and teeth,” the king said, “If you don't do this, you'll have a beating.”

    The doctors thought it impossible, but they dared not say anything against the king's order. Just then and old doctor stepped forward. “Oh, we shall certainly obey your order,” he said, but it takes time. We have to dig a mineral from the KunLun Mountains when the snow melts for the second time. The snow melts on those mountains only once in six years. So we need twelve years.”

    At last the king agreed and the doctors took away the little princess. On her twelfth birthday, they brought her back to her parents with long black hair and beautiful teeth. The king and queen were very happy and gave the doctors expensive presents.

    I was working the overnight shift in a remote hospital in the Rocky Mountains. Late in the evening, a young African teenager was brought into the emergency department. He lived at sea level and had never been in the mountains. After skiing all day, he felt really ill. Everyone assumed it was altitude sickness.

    He was sweating and had abdominal (腹部的) pain. His heart rate increased. We sent off his lab work, and his blood sugar came back at almost 600 — normal is less than 100. His platelets (血小板), necessary for stopping bleeding, came in at 10,000; they should have been over 150,000. I did an ultrasound of his abdomen, and it looked like his belly was full of blood. This wasn't altitude sickness. And in the short time I'd been trying to figure out what was wrong, he was getting sicker. The friends he was traveling with were terrified, and rightly so.

    The mystery was finally solved with an old-fashioned microscope. When we looked at his blood, we saw some sickled (镰形的) red blood cells. That's how we were able to diagnose sickle cell trait. If you have sickle cell trait — which means you got the sickle cell gene from just one parent instead of two — you have no symptoms at low altitude, but high altitude can sometimes cause the red blood cells to turn into sickle shapes and take oxygen from vital organs. This teenager didn't know he had it, but the effect of the altitude on his blood cells was so extreme that after just a short time in the mountains, he suffered great pain.

    He needed platelets immediately, but we didn't have enough at the remote hospital. And there was a snowstorm, so the medical helicopters couldn't fly. It was a scary night. Just as we were abandoning all hope, we met an ambulance that drove halfway up from the city with blood products and transferred him to the city hospital for emergency surgery. The story has a happy ending: He recovered fully.

    After a homeless man offered a college student in England all the money he had so she'd be able to get home safely, the woman is paying it forward—in a massive way.

    The story began in early December. It was about 3 a.m. and Harrison-Bentzen was panic. “I came out after a student night out and realized I didn't have any battery on my phone. I'd lost my friends,” the 22-year-old told BBC Radio 5. She'd also lost her bank card, she discovered, and she had no money.

    Just then, a homeless man, known only as Robbie, approached the young woman and asked her if she needed help. He reached into his pocket and pulled out all the money he had—loose change amounting to about $4.60. He insisted that Harrison-Bentzen take it to pay for a taxi so she'd get home safely.

    Harrison-Bentzen, a student at the University of Central Lancashire in Preston, England, says she refused to take Robbie's money and found another way to get home. But following her encounter（偶然相遇）with the generous man, she says she couldn't get him out of her mind.

    For the next few days, the student searched for Robbie, driving around the streets with her mom and using social media in an attempt to locate the man. In that time, Harrison-Bentzen says she learned more about Robbie and discovered that he actually had a reputation for helping strangers.

    Finally, after four days of driving around Preston, Harrison-Bentzen found Robbie. She was determined to do something to help change Robbie's life.

    So, earlier this month, the student launched a fundraising campaign in Robbie's name. She explained that she would be spending 24 hours on the streets, so as to “understand the difficulties” that the homeless face on a daily basis.

    Harrison-Bentzen says she had initially（最初）hoped to raise about $780 with her campaign. Her expectations, however, were quickly blown out of the water. As of Thursday morning, 4,800 people have donated almost $50,000.

Jack Horner is co-author of the book How to Build a Dinosaur. However, he is most famous for his role as consultant(顾问) on all four Jurassic Park films, including the new film Jurassic World.

The original film Jurassic Park tells the story of a theme park where dinosaurs live. In that movie, scientists used DNA collected by ancient mosquitoes that had been trapped in amber shortly after they drank dinosaur blood. The scientists used this dinosaur DNA to create baby dinosaurs. The scientists in Jurassic Park created various types of dinosaurs, but in the real world there is one big problem with the story. It turns out that DNA could not possibly survive the 65 million years since the death of the dinosaurs.

The new movie creates the Indominus Rex. This idea of creating a hybrid species is something Horner has explored before. In 2011, he gave a speech in which he discussed producing a dinosaur by working with the genes of a bird. Modern birds are the closest living relative of dinosaurs.

The concept of using the genes of different animals to create new animals is called transgenic science. And this type of science has already produced some interesting results — goats that produce spider silk in their milk, cows that produce proteins for medicines that can treat diseases, and a pig that produces less-polluting waste thanks to a bit of mouse DNA. However, none of these examples are close to the dinosaurs in Jurassic World. And for a good reason — genetics is a very complex science. Producing a new species is not as simple as just exchanging a few genes around.

In the end, Jurassic World is all about fun.
