Yet ever since she’d fallen off her bike and broken her arm, she’d been afraid. “Oh honey,” I said. “I don’t think you’ll break another arm.” “But I could, couldn’t I?” “Yes,” I admitted, and found myself struggling for the right thing to say. “I don’t think I want to ride,” she said and got off her bike. We walked away and sat down beside a tree. “Don’t you want to ride with your friends?” I asked. “And I thought you were hoping to start riding your bike to school next year,” I added. “I was,” she said in a low voice. “You know, honey,” I said. “Most everything you do comes with dangers. You could break your arm at gymnastics. Do you want to stop going to the gym?” “No, of course not!” she replied. And with a determined spirit, she stood up and agreed to try again. I held on to the back of her bike until she found the courage to say, “Let’s go!” I spent the rest of the afternoon at the park watching a very brave little girl overcome a fear, and congratulating myself for being an independent single parent. As we walked home, pushing the bike as we made our way along the sidewalk, she asked me about a conversation she’d overheard me having with my mother the night before. “Why were you and Grandma arguing last night?” “It’s nothing.” I told her. She shrugged (耸肩). “Grandma said she just wanted you to find someone to love.” “What Grandma wants is for some guy to break my heart again,” I snapped. “But Mom …” “You’re too young to understand.” I told her. She was quiet for the next few minutes. Then she looked up and in a small voice said, “So I guess love isn’t like a broken arm.” Unable to answer, we walked the rest of the way in silence. When I got home, I let go and agreed to meet a man called Steve. Steve was the man for me. We married less than a year later. It turned out my mother and my daughter were right. 57.

Nuclear, wind, or solar power? According to scientists at the Massachusetts Institute of Technology (MIT) in the US, it might be leaves – but man-made ones. Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用). Now researchers have found a way to copy this seemingly simple process. The man-made leaf developed by Daniel Nocera and his partners at MIT can be seen as a special chip with catalysts (催化剂). Similar to natural leaves, it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell (电池), which uses those two materials to produce electricity. A man-made leaf is not a new idea. The first man-made leaf was invented in 1997 but was too expensive and changeable for practical use. The new leaf, on the contrary, is made of cheap materials, easy to use and highly stable. In laboratory studies, Nocera showed that a man-made leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity. The wonderful improvements come from Nocera’s recent discovery of several powerful, new, inexpensive catalysts. These catalysts make the energy change inside the leaf more efficient with water and sunlight. Right now, the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides, the machine can run in whatever water is available; that is, it doesn’t need pure water. This is important for some countries that don’t have enough pure water. With the goal to “make each home its own power station” and “giving energy to the poor”, scientists believe that the new machine could be widely used in developing countries, especially in India and rural China. 61.
