    It was Saturday again. Grace and Karen disliked Saturdays. That was another thing the twins had in common. They shared the same clothes and tied their hair in the same manner. In fact, it was hard for their classmates and teachers to tell them apart sometimes.

    Unlike their classmates, they had to get up early every Saturday to prepare for their lessons. Grace had to attend the art lesson and Karen had to attend her ballet lesson. "How I wish I could do something different today," said the twins with one voice. All at once, an idea came to Grace and Karen at the same time. "How would you like to be me for a day?" they asked each other. It seemed like a wonderful plan to them. After giving each other a description of their own mends. Grace put on Karen's ballet dress while Karen put Grace's brushes and paints into her bag. Then they left for their classes.

    When the art lesson started, Karen was lost. Unlike Grace, Karen was poor at drawing. When the art lesson finally ended, Karen didn't dare to hand in her work.

    Meanwhile, Grace was struggling in the ballet class as well. As she had no idea about the dance steps, she had to follow her classmates blindly. As a result, she kept knocking into them. Their ballet teacher became impatient with her, "Karen, you should remember the basic steps. You can't rely on copying what others are doing."

    When Karen and Grace got home, they were tired out. They decided that they would never try to be someone else they were not. It seemed that the grass was not always greener on the other side.

    Students who get tired of looking at the four walls of a classroom might like to take the nature course being offered by Carvel College again this summer. Groups of about a dozen students each, led by an experienced guide, will go on ten-day camping trips to the mountains to study the plants and animals that grow and live there.（51题依据）

    Students carry their own things, which includes sleeping bags, warm clothing, food and water, and other useful tools. And what do the students do all day? Well, as soon as the sun comes up, they eat breakfast and start climbing up the mountain trail to the next campground（54题依据）, which is five to ten miles away. As the students take notes, the guide points out different plants and animals alongside the trail. The climb is usually over by early afternoon, so the group spends the rest of the day resting or swimming in a mountain lake. Before dinner each night, they all come together and discuss the day's activities.

    At the end of the course, the students write reports using the information they have collected. But they don't mind at all. What they do mind is leaving the beauty of the wilderness and the good friends they've made to return to their normal lives in the city.

    Betty and I are best friends. Our birthdays are on the same day, so every year we have a birthday party together. But this year, we had a costume party instead.

    While we were writing the invitations, my mum came in and asked, "Why not invite John?" John had been in our class for only a few months, but he had already got better grades in math than anyone else in class. I wrinkled(皱起) my nose," Mum, he wears the same pants to school every day. How could he even afford a costume?" Mum said nothing. The next day, Mum gave me an envelope(信封) with a shopping card in it. "I thought it would be nice for you to give this to John," Mum said. But how? We didn't want to make John embarrassed. We discussed it for a long time. Finally, Betty and I had a good idea.

    On the day of our party, kids arrived, dressed differently. John arrived, in an old sheet(床单), but still in the same brown pants as usual. We danced, ate snacks and played games in groups. Before eating the birthday cake, Betty said in a loud voice," Now it's time for the great prize game. It's the following riddle..."It was a math game. None of us was surprised when John came up with the right answer first and walked off with the envelope.

    Everything went on well as we planned. John wore a new pair of pants and a new shirt the next week. He felt happy. So did we.

    When we help others, we need to find a proper way, or we may hurt them in another way.
