The teacher stands before his class and is going to hand out the final exam papers. “I know how ________ you have all worked for this test,” he says. “and because I know you can do it well, I am going to give a B to anyone who doesn’t ________ to take the test.”

Many students jump up to ________ the teacher and leave the classroom. The teacher ________ the remaining (剩下的) students and says, “Does anyone else want to get a B? This is your ________ chance.” Two more students decide (决定) to ________.

Seven students remain. The teacher then hands out the ________. There are only 3 sentences on the paper: Congratulations! (祝贺) You just ________ an A in this class. Keep believing in ________.

I ________ had a teacher like that, but I think it is a test that any teacher could and should give. Students who don’t believe in what they have ________ are just B students.

The same is true in real life. The A students are those who believe in what they are doing because they have ________ both success and failure (失败). They have learned life lessons and have become ________ people. You are a big child now, and you ________ that you have some weaknesses(缺点). However, there is ________ you can’t do or learn.

When I was a child, watermelon (西瓜) was too expensive for my family. One of my father’s friends, Bernie,was a rich businessman. He owned a large fruit store in another place.

Every summer, when the first watermelons arrived, Bernie would give us a call. My father and I would go to Bernie’s place. We would sit on the dock (码头) happily and get ready for a big meal.

Bernie would take a big watermelon out, cut it up, give us both a big piece and sit down next to us. Then we three would put our faces into the watermelon, eating it happily.

In my father’s eyes, Bernie was a real rich man. I always thought it was because he was a successful businessman. Later I learned that it was not Bernie’s money that made my father think like that. My father thought he was rich because of the way he lived his life. Bernie knew when to stop working, get together with friends and enjoy his “watermelon”.

When I grew up, because I was too busy making money as a doctor, I forgot the lesson I once learned on the dock. Well, now I’ve relearned it. Though (尽管) I’m still busy working as a doctor, I will try to slow down and take the time to enjoy the small pleasures (快乐) of my life.

①It’s often believed that only grown-ups can make a difference (产生影响). Is it true? Teen Vogue interviews (采访) some teenagers across the world. Get ready to be inspired (启发).

②16-year-old Michael starts using social media (媒体) to cheer up teenagers of his age to follow their dreams on his baseball blogs (博客). Michael also writes about sports people and how they will face their challenges.

③Lesein, 14 years old, first learns about climate change when he is twelve years old. His home country of Kenya loses about 29,650 acres (英亩) of forest each year.

④With a deep love of soccer, Lesein starts Trees for Goals, planting a tree for every goal he scores in a match. Later the school’s soccer and basketball teams all follow him. In 2019, almost 1,000 trees in forests outside of Nairobi are planted. Now the government provides (提供) trees for them to plant.

⑤Alexis Lewis, a 15-year-old inventor, designs a simple wheelchair with bamboo to help poor people who need to transport children many miles to hospitals. Another invention of his is a special mask which can be thrown through a window of a smoke-filled building to people inside.

⑥Alexis said, “People are dying because they can’t be saved in time. Another reason why I want to invent something is that I love physics and I use it to improve technologies.” Alexis also tells our reporter that he wants children to know that ________.

⑦These young people are certainly shining examples to show you’re never too young to make a difference.

I am having a good time visiting my aunt in Thailand now. She is working here. It’s really a beautiful place. You can do a lot here. I like outdoor activities like     41    , biking and diving (潜水). All of these are wonderful. I visit many temples (寺庙) and learn about their history. I also learn a lot about elephants here. The elephant is one of Thailand’s     42    . The first flag of Thailand had a white elephant on it. Elephants can play soccer or music. They can walk for a long time and never get     43    . They can also remember places     44     food and water. It’s really cool, isn’t it? I also miss my parents very much. I like Thailand and my vacation here, but there is     45     “no place like home”.

Alan is a cute boy. He often goes to a park with his dad in     46     (they) free time.

There is a swimming pool in the park, and Alan often sees many     47     (child) there. They swim     48     (happy) in summer. He     49     (wish) that he can swim in a river or a lake someday.     50     he knows that he must learn how to swim in a pool first.

    51     the morning of Sunday, while dad is still     52     (sleep), Alan wakes him up. Then the boy asks Dad     53     (take) him to the park.

“Why do you want to go there? It’s so hot today,” Dad asks.

“I want to learn swimming,” says Alan, “And you can teach me there.”

“Oh, I’m sorry. But I can’t swim,” Dad answers.

“You can’t swim? Jack’s dad swims very     54     (good). Why can’t you swim?” Alan feels quite surprised.

“His dad likes eating fish, so he can swim     55     a fish,” Dad says.

“Oh, I see,” says Alan, “But you like eating chicken very much. Can you lay eggs (下蛋)?"
