I believe that we can have an important effect on anyone we meet. The right words at just the right time could change someone's life. When I was three years old, my parents discovered I was deaf. After asking many doctors and parents of other deaf children, they decided to put me in a normal school.

    On my first day in the school, the other kids made fun of me because of my hearing aid. And then I saw myself as an ugly kid.

    Mrs. Jordan, my teacher changed all of that with a simple three-word phrase. One morning, she asked the class a question. I read her lips（嘴唇） and raised my hand right away. She called me. I took a deep breath and nervously answered Mrs. Jordan's question.

    I will never forget what happened next. Mrs. Jordan pointed directly at me. With a big smile she cried,

    "That's right, Stephen! "For the first time in my young life, my confidence soared（剧增）.At that moment, I decided that no matter how many difficulties I may face, I can overcome（克服） them. Just from those three simple words, my life changed from that moment.

    A young woman traveled and stayed in a hotel. All the rooms in the hotel were singles(单人间). So she lived in a single room.

    Just when she was going to bed, there was a knock at the door. She had no friends in the city. So she was quite surprised but still opened the door.

    The man who was standing at the door looked a little nervous. "Oh! I'm sorry. I thought this was my room," the man said and walked away in a hurry.

    The woman called the police at once. Soon, the man was caught. He was a thief(小偷)! But how did the woman know that?

    All the rooms in the hotel were singles. Who would knock at his own door if he was staying alone? Only a thief would do this. He wanted to see if anyone was inside before he broke into the room.

    This morning I woke up being a little bit worried. Too many unlucky things happened and I needed to make many decisions. I decided to go for a walk and tried to relax. On the way, I kept repeating to myself," Don't stop being kind. Others may have worse situations than me." I already felt better when walking in the park enjoying the beautiful trees and the smiles to and from strangers. I decided to go shopping on my way back.

    After paying. I sat-down for a while and got a coffee. An elderly man sat next to me and started talking very loudly. I noticed that he had hearing aids(助听器)in both cars. He had a coffee too. I tried talking with him, but I realized he could not under-stand anything. I stayed anyway and he told me about his difficulties with hearing, his son who worked in the supermarket and that he was at the age of 89! He felt happy to still be able to do the shopping on his own.

    He said he liked talking to people and he apologized many times. I told him it was lovely to talk to him and after a while I said goodbye, shook his hands and wished him a good day. He was so happy and grateful(感激的).He thanked me many times and the last thing he said was" Thank you for listening". I thought the whole point was" I just stayed and listened".

    Life is full of surprises and you never know how things will turn out.

    Sir John Gurdon is a good example of this. As a boy, he was told he was hopeless at science and was at bottom of his class. Now, aged 79, the very same Gurdon shared the 2012 Nobel Prize in Medicine with Japanese stem cell (干细胞) researcher Shinya Yamanaka.

    Like so many scientists, Gurdon shows us where the power of curiosity and perseverance(坚持) can lead.

    When he was 15 in 1948, Gurdon ranked last out of the 250 boys at his high school in biology and every other science subject. Gurdon's high school science teacher even said that his dream of becoming a scientist was "quite ridiculous".

    In spite of his teacher's criticisms(批评), Gurdon followed his curiosity and kept working hard. He went to the lab early and left later than anyone else. He experienced thousands of failures.

    "My own belief is that we will, in the end, understand everything about how cells actually work," Gurdon said.

    In 1962, Gurdon took a cell from an adult frog and moved its genetic (基因的) information into an egg cell. The egg cell then grew into a clone of the adult frog. This technique later helped to create the sheep Dolly in 1996，the first cloned mammal(哺乳动物) in the world.

    In 2006, Gurdon's work was developed by Yamanaka to show that a sample(样本) of a person's skin can be used to create stem cells. Using this technique, doctors can repair a patient's heart after a heart attack.

    "Luck favors the prepared mind," Gurdon told the Nobel Prize Organization. "Ninety percent of the time things don't work, but when they do, you have to seize(抓住) the chance."

On a hot summer day, Holmes and Dr. Watson went on a camping trip. After a good meal and a bottle of wine, they lay down in a tent for the night and went to sleep. Some hours later, Holmes woke up and pushed his friend. "Watson, look! What can you see in the sky?" Watson answered, "I see millions and millions of stars." "What does that tell you?" asked Holmes. Watson thought for a while. "First, it tells me that we will have a beautiful clear day tomorrow. Second, it tells me that the time is about twelve o'clock. And..." "What else?" Holmes asked. "Well, it also reminds me that the world is so big and we are so small. What does that tell you?" Holmes said with a grin (咧着嘴笑) on his face, "You silly guy! It only tells me that someone has stolen our tent!"
