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.

At the beginning of the school year, each student would be given a special job for which they would be responsible (负责任的) for the whole term. Rita, a quiet and hardworking girl, hoped for an exciting task, like taking care of the class plants. Instead, she received a small box with sand and a small ant. 

Even though the teacher explained that this task was very special, Rita could not help feeling disappointed. However, she decided to do her best with her new job. She began to study and care for the ant, learning about its habitat (栖息地) and needs. She made the box a comfortable home for the ant, and it grew much bigger than anyone expected. 

Rita's efforts caught the attention of her science teacher, Mr. Thompson. He turned her work into a class project, and Rita became the class expert (专家) on ants. Her hard work helped the whole class learn about ant behavior and habitats. They even built a small ant farm in the classroom to observe the ant closely. 

Gradually, Rita's classmates became more and more interested in the ant project. They started asking her questions and observing the ant's behavior themselves. Rita organized a presentation where she shared her findings with the whole school during the science fair. 

At the end of the year, Rita's class was recognized as the best of the year. Rita was as well praised for her hard work and how she turned a small task into something big. Rita learned that every task, no matter how small, could make a big difference. She also learned that sometimes the most unexpected things can lead to great success.

Amy: My throat hurts and I have a cough for many days.

Sally: So bad. {#blank#}3{#/blank#}

Amy: Yes, but I still feel bad.

Amy: Yes, you're right. Maybe I should ask for a leave to rest for a few days.

Sally: You also need to drink more water and take the medicine on time.

Stamp collecting is a fun way for children to learn about the world.{#blank#}1{#/blank#} When the child collects a stamp from a different country, he can find the place on the map and put the stamp there. 

Strangely (奇怪) enough, the first stamp collectors were children. When they grew up, they kept collecting stamps.{#blank#}2{#/blank#} Today, many children still have this hobby because it's interesting. {#blank#}3{#/blank#} If a child is collecting stamps from different countries, he will ask everyone he knows to send him a letter from any country they visit. 

Many children just like pretty stamps - they really don't care what kind of stamp.{#blank#}4{#/blank#} They like to collect stamps with cartoon characters and lovely animals on them. 

Wang Xinyao and her parents will never forget the special day— July 22nd, 2022. On that day, Wang 1 the admission letter (录取通知书) from Peking University in Beijing. Two important people from the university travelled to Wang's high school in Changchun, Jilin Province to give her the2 news. 

In the 2022 gaokao, Wang got a 3 of 618. As we know, it isn't easy for most high school students to 4 that high scores. And Peking University is most Chinese students' dream university. You can 5 how difficult it is for a girl who can't walk. Wang Xinyao hurt badly  6 she was practising dance moves at the age of 6. Her parents took her to many  7 in Beijing, but doctors said she would never walk.8 , her parents didn't give up. Over the next two years, the family9 in Beijing for Wang's rehabilitation (康复). 

"She often asked us when she could return to school and whether she would be 10 to walk and run like other children," her dad said. After returning to Changchun, they went to the local Education Bureau (教育局) for 11 . Finally Wang Xinyao went to study at Shuguang Primary School. 

"My daughter is 12 to meet so many kind teachers and classmates. From primary school to high school, her classrooms are always on the first floor," her dad said. To 13 the gaokao, Wang studied much harder. She never went to bed before midnight,14 during her third year. 

"I want to thank my parents, my teachers and classmates.15 their care and help, I would never have been able to make my dream come true," said Wang.
