Jack is my best friend. He is in a new school. He likes it very much. It's not far from his home. And it usually takes him 10 minutes to get to school by bike. School begins at 8: 00 every morning. But these days Jack is often late for school. This morning, he is late again. The teacher is very angry.

    "How do you usually come to school?" asks the teacher. "By bike." Jack answers. "What time do you usually get up?" "At 6: 30." "Well, it's not late. What time do you usually leave home?" "I leave home at 7: 55." "Why not leave home earlier?" "My mother is ill (生病的). She stays in bed all day. I must look after her and give her medicine at the right time， so I'm often late for school," says Jack with tears (泪水) in his eyes. "I see, Jack, you are a good boy!" says the teacher.

My family lived in a big city, and we had no garden, but I often {#blank#}1{#/blank#} (go, went) to a small park near my home. There {#blank#}2{#/blank#} (are, were) a lot of trees in the park. Early in spring, those trees{#blank#}3{#/blank#} (get, got) green. I liked to see all the green leaves. In summer there were flowers everywhere. I often {#blank#}4{#/blank#} (read, reads) picture hooks on the bench. In autumn, the leaves turned yellow and red. I often {#blank#}5{#/blank#} (take, took) a walk with my parents. I also{#blank#}6{#/blank#} (like, liked) to walk after supper with my grandpa. He {#blank#}7{#/blank#} (know, knew) a lot of stories.

Humans are mammals (哺乳动物). Most mammals are born able to do many things.

Some can walk within a few minutes of being born. They have to be able to run away if 1 is near. But human babies are born 2. They need the care of adults to live.

In the first month of life, babies can not smile or sit up. They can not even hold up their own heads 3 some help from grown-ups.

In the next few months, babies grow a lot. They learn to roll over, support their heads, and 4 sit up while being held.

Babies also have to learn to use their 5. It takes months for them to learn to reach for objects. At around six months old many babies can 6 an object from one hand to another.

Babbling is 7 a human baby learns to speak. Babies all seem to make similar sounds by babbling. They try to imitate (模仿) the sounds they hear from adults. It will take about nine months 8 a baby can say real words.

Somewhere around a baby's first birthday he or she may stand or walk with help. Soon the baby will 9 around on his or her own!

The first year of a baby's life is a time of growing and 10. Growing sure takes a lot of work!

Dear Mum，

Many people say they have the best mum. But I think that I have the best mum in the world. There's so much to thank you. I don't know where to start, but I will try. 

♥Thank you for looking after me. You are there at hospital visits, plays, everything. Whenever I need you, you are always there and you will always be. 

♥Thank you for being my best friend now. You're the one to whom I tell everything. Every time I need someone, you are my fan. 

♥Thank you for loving me. You tell me that you love me every day. 

And you know what, I love you, too. 

Love，

Your Daughter

This summer, when I walked into my grandparents ' house with my little brother Frank, I tried not to look at Grandpa's chair anyway. It still  looked the same. His blue 1 was  there, as if ( 好 像 ) Grandpa was going to pull it over his legs. My cousin Jack was playing in the yard as if 2 had happened. "Let's go to catch fish!" Jack 3 the fish net from the corner, Grandpa's net.

Last summer, I was holding the net when Grandpa asked me 4 I could help him teach Frank how to play chess. I said no because I wanted to catch fish. Grandpa had been the one who'd taught us how to catch fish, but then the 5 made him stay behind.

I regretted saying no to Grandpa, and now I wouldn't have 6 to play chess with him.

When we reached the stream, we began to catch fish. Suddenly, Jack shouted, "Frank is shaking." We hadn't brought anything to keep 7 so I had to send him home.

Grandma was worried to see a wet Frank and 8 put Grandpa's blue blanket around him. As I went to the stream again to meet Jack, I looked back at Frank with that old blanket. Something seemed to 9 me at that moment. Everything was just like before, but Grandpa was gone.

I walked to Frank. "Did Grandpa teach you to play chess last summer?" I asked. "No, Grandpa was too sick then." he said, "I miss him."

"Me, too." When I said it, I knew Grandpa was never gone. What 10 us was still there. It could be the fish net. It could be the chess. It could be the blue blanket.

A European Union program is letting blind people experience famous paintings for the first time. It uses three dimensional（3-D） printing to recreate famous paintings so they can be touched. 

One painting printed with the new technology is Gustav Klimt's "The Kiss". It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes（长袍） and have their arms around each other. The man leans down to kiss the woman. 

Klimt finished the painting in 

1908. Until now, people who had trouble seeing could not appreciate the artwork. But thanks to the reproduction（复制品）, they can touch the piece and feel the ridges（隆起） and depressions. Andreas Reichinger said this reproduction was his most difficult project because the couple's robes are so detailed. 

Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it she said, "Exactly, can you see these? There are so many details. " Raditsch said she could imagine what the original painting looked like when she touched the reproduction. "It's somehow round. You can feel it. It comes with it. And in many places it's so smooth. And then I think to myself — it probably shines, too!" Raditsch said. 

The Belvedere is not the only museum to have 3-D versions of its artwork. Some of the pieces at the Prado, in Madrid, Spain, have reproductions that can be touched. But the piece in Vienna has one special part: it is made with widely available 3-D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.
