Mason has seen the future—and it's fun. Mason likes thinking about how machines can make our life easier by doing the work we hate, such as cleaning. He shows a floor cleaning machine that's built into the wall. It can clean up the floor.

    When it comes to the kitchen, Bruce, an expert at Whirlpool, is sure that in a few years, robots will be doing most of the boring work, freeing us to relax. "More than just fun, future kitchens will be environmentally friendly," he says. A new system will be built in the house which can recycle energy lost from your kitchen to make the whole home warm.

    "The fridge will be the centre of the home," says Daniel, a market expert. The fridge will have a touch screen (触摸屏幕) where you can watch TV, surf the Internet, check your emails, keep a shopping list and order vegetables. "Your fridge is the first place you go to in the morning and the last place at night," says Daniel.

    "I wonder why a 1.9-metre man and 1.6-metre woman have to cook meals on counters (柜台) of the same height," Jane Langmuir, an expert of cooking machines, says. "But times have changed. We have made a new counter where you can press a button and it moves to whatever height you want."

    Ted Selker has made the dish maker which lets you make dishes and bowls out of plastics at home. After each meal, the dishes are changed straight back into plastics.

    Last year, I went to a summer camp in the United States with my classmates. It was my first time to go abroad.

    I lived with a host family in Los Angeles for five days. My host family was friendly and gave me lots of advice. For example, they said I should say "excuse me" if I have to interrupt (打断) someone or ask for directions.

    I also took some classes. They were different from the classes I had had back home. In the US, each class is like a seminar. Students join groups, speaking freely and creating a cheerful atmosphere (氛围). I had to work hard to learn more vocabularies, so I could better communicate with my international classmates. I used to pay little attention to my word usage (使用), but now I pay more attention.

    During my visit, I also went to some famous universities in Boston, New York and Washington, D. C. We learned about the history behind the universities. At MIT (麻省理工学院), we saw lots of names on a wall in the hall. The tour guide told us they were the names of students who had lost their lives during wars. I was inspired (鼓舞) by the fact that they fought for their country.

    One day, Jack's parents told him that his grandpa would retire (退休) after working for forty years. Jack said1, "I'm only seven, so it means my grandpa has been…er…a really long time!"

    His parents said, "Yes. There is a (n)2place in his heart that we don't know how to fill. That's why we are going to have a surprise party for him."

    Jack loved his grandpa and wanted to do something3for him. He remembered the business card his grandpa had given him two years before. He knew that his grandpa would no longer hold the position on that card, so he decided to build a new one for his grandpa.

    When the big night came, Jack was4. He put his gift in a small box. But he didn't want to put his gift together with others'. He carried it around with him the whole5.

    When all the other people6, he took his grandpa's hand and brought him over to a chair and gave him the gift.

    His grandpa smiled, "Well, it must be a beautiful7. May I open it now?" "Sure!" Jack said excitedly.

    As Jack's grandpa opened the gift, tears came into his eyes. He was touched by Jack's gift. Jack gave him the greatest gift he had8got! It was a business card with his new position FULL-TIME GRANDPA! Jack said, "Now your9job is my grandpa."

    "Well10do l get paid?" his grandpa asked, smiling. "As many hugs (拥抱) as you want!" With these words, Jack gave his grandpa a hug. "Well, I guess that means I'm the richest man in the world!" said the grandpa.

    Nearly 7,000 medical workers in the team supporting Central China's Hubei province left the capital, Wuhan, the hardest-hit city in the novel coronavirus outbreak in China, and went back to their hometowns on Tuesday, March 31, marking the largest scale departure (离开) of medics (医学工作者)since the first group left on March 17. The Civil Aviation Administration of China has organized 51 planes to support the departure.

    More than 42,000 medics from other parts of the country have joined the battle with local medics to fight against COVID-19. The support teams came from 21 provinces, cities and autonomous regions(自治区) and some of them worked on several battlefields during the past months. The support team from the First Hospital of China Medical University in Shenyang, was among those in the group. Sixty members were in charge of treating COVID-19 patients in 100 beds in the Union Hospital and treated 174 patients who have been seriously ill since they arrived on Feb 10.

    Wang Zhenning, the leader of its support team, expressed his thanks to the Wuhan people who offered great help to them. "I am proud to witness and play a role in history. We've been here, seen it happen and become better. Wuhan is our second hometown. We will forever care about the city and the people fighting with us." he said.

    Wuhan city government showed great thanks to all medics in a letter, expressing their gratefulness of the medics' efforts to save lives in the battle. "Thanks to your arrival, Wuhan welcomes today's peace and stability. We will always remember your kindness!" the letter said. In it, the city government also invited the medics to visit Wuhan in the future for sightseeing. Local people volunteered to line up and see medics off as the medics left for home after finishing their mission(使命) in Wuhan. Wuhan traffic police led the way for medics to the airport.

I have a friend named Monty Roberts who owns a horse ranch （牧场）. He has let me use his 1 to raise money for youth at risk programs. 

The last time I was there he told me his story. When he was young, his family is too 2 to have a house to live in. As a 3 , he had a poor childhood. When he was in high school, he was asked to write a paper about what he wanted to be and do when he grew up. That night he wrote a seven- page paper describing his goal of 4 a horse ranch. He also drew a picture to show a 4000- square- foot house that would sit on a beautiful farm. The next day he 5 it in to his teacher. Two days later he received his paper back. On the front page was a large red F. Roberts asked, "Why did I 6 an F?" His teacher said, "This is a （an）7 dream for a young boy like you. A horse ranch requires a lot of money. " Then the teacher added, "If you will rewrite this paper with a more realistic （现实的） goal, I will reconsider your grade. "

The boy went home and thought about it for a （an）8 and hard time. He asked his father what he should do. His father said, "Look, son, you have to have your own mind on this. " Finally, after sitting with it for a week, the boy turned in the same paper, making no 9 at all. He told his teacher, "You could keep the F and I still keep my dream. "

Monty tells me this story because I am sitting in his 4000- square- foot house in the middle of my 200- acre horse ranch. He said a lot of kids' dream can be stolen. Don't let anyone steal your dreams. Follow your heart, no matter what happens. 10 he had enough courage not to give up his dream.
