Ⅱ. 阅读表达【主题：人与社会 了解世界的最好方式】
Science is the best way we have of finding out about the world. Scientists collect evidence (证据). They have ideas about the way things work. Science tests those ideas. Sometimes the test will show that the idea is not correct. If the idea passes the test, it adds to our understanding.
Scientists make observations (观察). They may look, or listen. They may read the work of other scientists. This gives them ideas. You can do this. You can look around you. You can ask questions. You can plan a test to find out. You can discover something new.
Scientists make predictions. They say something about the future. They might say if I do this, then I think that will happen. Isaac Newton was a famous scientist. When he shone white light through a glass prism, he saw a spectrum (光谱) of different colours. Newton predicted what would happen if he shone the spectrum through a second prism. He thought the colours would come together and he would see white light again. He tried it. He shone a spectrum through a second prism. He was right. The colours made white light. He discovered that white light is made up of many colours.
It's important to test your ideas. It's important to plan a fair test. A scientist wondered how a tree grows. Where does all that material come from? Was it from the soil? He planted a young tree in a pot. He weighed the pot, the dry soil and the tree at the start of his test. Years later, the tree had grown tall. It had many branches and leaves. The scientist dug it up. He weighed it. The tree weighed far more than when it was young. Then he weighed the pot and the dry soil. It weighed just a bit less. Where had all the new tree material come from? He decided that trees use water, and a gas from the air, to grow.
