2 . Several years ago, I spent most of my time at a mental hospital (精神病院) in our town. I found much joy there. At first it was a little scary to be there, but I stayed on, because I had a reason for doing this.

I volunteered in a locked-up (封闭的) environment. To my surprise, I found that a friend of my parents’ was a patient in this hospital. I knew, when I was a baby, this woman wanted to keep me because she had no children. I looked after this woman and showed my old photos to her. Finally, she was able to remember some old things, and she said to me one day, “Dear, you should not come here.” But I wanted to bring something happy into this woman’s life. I learned that because she had no family, she couldn’t leave here and go home. So I brought her to my home twice and I still remembered the happy smile on her face.

I have never forgotten this volunteering experience. This woman later passed away. I can’t see her anymore, but I’m happy that I have done something to make a difference in another person’s life.

Little Dora always wanted a sister. So when Mum told her she would have one in six months, she felt very ________. But Dora had to be away for some time. She had promised to stay with her grandparents till autumn came.

“How can I make ________ go faster? I can’t wait to see the ________.” Dora said to herself while she was sitting in her grandparents’ yard one day. She had a good ________ when she saw the apple tree in the yard. She decided to ________ a picture of the tree each day. As Grandpa said, by the time she saw red apples on the tree, she would have a sister!

Dora’s first picture was a tree full of green leaves. Day by day, the weather got cooler. The leaves slowly ________ their colour and tiny apples appeared among them.

________, Dora drew her last picture of the tree. It had a lot of red apples. Now it was time to return home. When she entered the house, Mum and Dad were ________ her on the sofa. Each of them was ________ a baby in their arms.

“Now you have a sister and a brother!” Dad said. “Wow, I’m the ________ sister in the world!” Dora said happily. “Look! Their faces are as round as red apples. They are so cute.”

7 . About 80% of people do not get enough vitamin (维生素) D every day. But this vitamin is very important for your health.

Vitamin D is really important for our bones (骨骼). When we are young, vitamin D builds up our bones and makes them strong. When we are older, we still need vitamin D to keep our bones strong. Our bodies keep the vitamin D in our bones and teeth. Then we lose vitamin D as we work and exercise during the day. But our bodies can’t make vitamin D. So we have to get it from outside of our bodies.

Where can a person get this very important vitamin? Vitamin D is in foods like fish and eggs. Sometimes, vitamin D is added to bread, milk, and orange juice. Food is not the only way our bodies can get vitamin D. The sun also gives us vitamin D. If we want to be healthy, we should spend some time in the sun each day. Too much sun is not good for you, but about 15 minutes a day is usually enough. And we should be sure to eat foods that are rich in vitamin D, too.
