My name is Liu Na. I'm unhappy because I'm getting heavy. I'm sorry to say that I exercise 1 than once a week. I know it is not a2way of living for a 14-year old girl. But I really don't have much time to3. In fact, unlike other girls, I love4. I used to be a member of the swimming team and the5 team at school. I went 6 on Saturdays and played basketball after school on weekdays. 7 the sports teams last year, because I had to spend much more 8on my study. Now I have little time to play sports. I9 watch TV or play computer games, either.

    These days, my mother asks me to play sports with her. She 10 health is very important. I hope I can have time to exercise with her and lose weight(减肥).

    John was a manager in a factory. He enjoyed running for exercise around the park when he was free.

    One Sunday afternoon, after running as usual, John 1to go home and had a rest. Just then, he noticed an old woman standing by the road. 2old woman looked around worriedly. John went over and asked what 3 for her. After a short talk. John came to know that she forgot her way home and got lost. Besides, she was very tired and hungry. John called the old woman's son and then took her to the4restaurant.

    In the restaurant, John ordered food and drink for the old woman  5. While eating, sometimes she carelessly sprinkled(撒)food and drink on the table and on her coat. Other customers felt disgusted(厌悲的)at this sight. 6John didn't care about this. He stood up and cleaned the table from time to time 7 silence.

    It took the old woman some time 8 eating. After that, John paid the bill and they were ready to leave when the old woman's son arrived. He held John's hands and said, "Thanks to your help, my mother  9well" "You're welcome. She makes me remember my mom who died years ago. I did what a son should do, "said John. All the 10around showed respect(尊敬)to John. They were touched by his kindness.

Jerry is a world-famous mountain climber. He climbed many high mountains in the world. Starting in 2015, he and his friends spent two years on an adventure (探险) in South America. In 2018, a famous geography magazine even named him Adventure of the Year.

Although Jerry achieved great success, he didn't feel satisfied. He asked himself, "Is it enough to climb the highest mountains? Am I doing something helpful? How can I change my adventures into something that can help the world?"

Jerry learned that scientists need plants, rocks and water samples (样本) from the places far away to do research. But scientists can't get there themselves because such places are hard to reach—only the bravest adventurers can make it. Jerry thought he could do something to help. He then came up with an idea. He organized a team of top adventurers to collect samples for scientists. By studying the samples, scientists could know more about the earth and find ways to protect it.

Recently Jerry and his adventurer friends have discovered a special plant life of Mount Qomolangma. The samples they brought back have helped scientists study how plants live in extreme (极端的) condition.

For Jerry, this kind of adventure is most satisfying. "Such adventures had made us see life in a different way. Now, being the best climber isn't important for me. What matters is doing something helpful while climbing the mountains. There is still much more we can do," Jerry said to a newspaper.

Hello, everyone. I come from Zhejiang. I live in a beautiful town here. Would you like to learn something about my hometown? The name of my hometown is Wuzhen. It has a history of about 7,000 years. Wuzhen is Well-known（出名的）for its history and culture. And it is one of the most popular water towns in China. The old stone bridge, stone roads and houses make the town look very beautiful. The old canal（运河）runs through it. You can see some shops and restaurants along the canal. There are many tourist attractions（旅游景点）in the town. Xizha and Dongzha are two beautiful places in Wuzhen. Many people feel relaxed when they come here. In Xizha, some houses are hundreds of years old. But many people still live in some of them now. The colors of many old houses are grey and white. There are free buses and boats running between Dongzha and Xizha. And it only takes about 10 minutes if you want to walk between the two places. There are all kinds of historical sites（历史遗迹）, workshops, and relaxing places in Wuzhen. Come to my hometown and I believe you'll love it. 

In 1988, a serious earthquake hit Armenia. It killed(杀死)about 25,000 people in less than four1 . A father rushed to the school where his son was,2 to find that the building was flattened(变平).

But he remembered the3 he had made to his kid, "No matter4 happens, I'll always be there for you!" Tears began to fill his eyes. He ran5 to the place where his kid's classroom had been and started digging(挖掘).

Other parents tried to pull him out of what was left of the6 . To each parent, he asked in a7 voice, "Are you going to help me?" Then he went back and8 his digging, stone by stone.

He dug11 eight hours...18 hours... 28 hours... And then, in the 38th hour, he pulled back a12 and heard his son. He called his son's name, "ARMAND!" He heard back, "Dad? It's me. Dad! I told the other kids not to worry,13 I'm sure that you would come to save us."

"What's going on in there?" the father asked.

"There are 14 of us left out of 33, Dad," his son answered.

"Come on out, Son!"

"Let the other kids out14 . I know you'll get15 ! No matter what happens, I know you'll always be there for me!"
