    Andy woke up and looked at the clock 11: 30? He jumped out of bed and threw on clothes. He had wanted to get up early and surprise his dad with Father's Day breakfast in bed﹣with his mom's help of course. He took up the wrapped present on his desk and went to find his 1.

    "Where is Dad?" Andy checked all the rooms, but the whole house was empty. He walked out to the 2, and his jaw dropped. Dad was holding a hammer and looking at a new tree fort that stood in 3 big back yard.

    Andy climbed the rope ladder up to the fort. It had two rooms with three small windows.

    Dad followed Andy into the fort, looking excited. "I spent all morning 4 it. I had one when I was your age. Grandpa surprised me with it on Father's Day, too. "

    "So, it's like a（n） 5?" Andy asked.

    "Yes, this is a present for 6 of us. Maybe you'll build one for your son one day. "

    Dad looked around and asked Andy 7 they would do first in the tree fort. Andy slowly showed the 8 and said, "Happy Father's Day!" He didn't think it was possible, 9 Dad's smile widened as he opened the gift. "A chess set! How did you know I wanted 10?" Andy always saw his dad playing against the computer and he guessed it 11 be his father's favorite.

    "Let's play it!" Dad set up the chessboard. "It's the 12 gift I got of all this Father's Day. "

"I'm glad you like it." Andy said.

    "I do, but I was talking about spending more time with you. I 13 loved the father﹣son time. I spent a lot with your grandfather when I was 14. "

    Andy looked at his dad. "Can we call Grandpa and 15 him to come to the fort?"

Dad squeezed Andy's shoulder. "I think he'd love that."

    That day, the three men played, talked and laughed. It was really a happy Father's Day.

        In a nice house there lived an old man. Behind the house there was a big garden. He planted many plants there. He took care of his flowers all the time, watering and fertilizing (施肥) them.

       One day a young man went by the garden. He looked at the beautiful flowers, imagining how happy he could be if he lived in such a beautiful place. Then, suddenly he found the old gardener was blind. He was very _________ about this and asked, “You can't see these flowers. Why are you busy taking care of them every day?”

       The old man smiled and said, “I can tell you some reasons  . First, I was a gardener when I was young, and I really like this job. Second, although I can't see these flowers, I can touch them. Third, I can smell the sweetness of them. As to the last one, that's you.”       

       “Me? But you don't know me,” said the young man.

       “Yeah, it's true that I don't know you. But I know that flowers are angels that everybody knows. We enjoy the happiness these flowers have brought us.”

       The blind man's work opened our eyes and pleased our heart, which also made his life happier. It was just like Beethoven, who became deaf in his later life and wrote many great musical words. Beethoven himself couldn't hear  his wonderful music, but his music has encouraged millions of people to face their difficulties bravely. Isn't it one kind of happiness?

    Mr. Black comes into Class Three. The bell is ringing. He wants to teach an English lesson. Mr. White comes in and asks him to go to the office. He must go and have a meeting. Mr. Black says to his students, "You study by yourselves, please. I'll be back soon. "

    After a while, Mr. Black comes back. He sees Mike talking to his deskmate Jack. Mr. Black is very angry.

    "Stand up, Mike！" says the teacher. "What are you doing？"

    "I'm reading English now, " says Mike.

    "What's in your hand? Please look at it carefully, " says the teacher.

    Mike looks at it. Oh, it's a history book. He looks at Jack's hand. There is an English book in his hand. He has a good idea right away.

    "I'm sorry, Mr. Black. Jack is holding an English book and I am holding a history book. We are studying the history of English. "

    On March 14, one of science's brightest stars went dark. Stephen Hawking, the world-famous British scientist, died at 78 in Cambridge, UK.

    Hawking is considered by many to be the greatest scientist in history since Albert Einstein. He came up with the theory（理论） that the universe (宇宙) began with the Big Bang and will end in black holes. His theories became the base for a lot of later research. He also wrote books to help common people understand the universe. His most famous book is A Brief History of Time, which has sold more than 10 million copies around the world.

    Besides his scientific achievements, Hawking was also someone who had a strong will. When he was 21, he got a serious illness that stopped him from walking and talking. Later in life, he had to sit in a wheelchair and “speak” using a computerized voice. But this didn't stop him from living a meaningful and colorful life.

    He celebrated his 60th birthday by going up in a hot-air balloon; when he was 65, he took part in a zero-gravity (零重力) flight to experience weightlessness. He hoped to travel into space one day. In 2015, Hawking spoke about how he felt life was unfair when he first knew about his illness. “But now, 50 years later, I can be quietly satisfied with my life,” he said.
