Many people have only seen chemical reactions in textbooks. However, students can also create these reactions in class by themselves. They use different liquids to create amazing colour changes. They mix acids and bases, and watch bubbles form and colours change. First, students prepare the liquids and measure them carefully. Then they mix them in a test tube. After a few seconds, the chemical reaction happens — the liquid turns from clear to blue, or from yellow to red! "It sounds easy, but it's not. When we mixed the liquids, we often added the wrong amount. After many failures, we finally got the perfect colour change," said student Wang Fang. "The lesson is so fun and creative!" said another student. "It shows us that science is not boring. Chemistry is like magic, and we can all be magicians!" ( )1. What do students use to create colour changes in class? A. Different plants. B. Different liquids. C. Different paints. D. Different foods. ( )2. What does the underlined word "failures" mean in Chinese? A. 成功 B. 失败 C. 竞争 D. 影响 ( )3. Why did students often make mistakes during the experiment? A. They used the wrong test tubes. B. They added the wrong amount of liquids. C. They mixed liquids too slowly. D. They forgot to stir the liquids. ( )4. What do the students think of the chemistry experiment project? A. Boring and difficult. B. Useful but boring. C. Enjoyable and creative. D. Easy and enjoyable. ( )5. What is the best title for this passage? A. Students' Homework After School B. How to Mix Colours C. A Special and Fun Chemistry Lesson D. Different Types of Liquids 八、阅读表达（阅读短文，根据短文内容回答下列问题，每题2分，共10分） Marie Curie — A Great Scientist Marie Curie was a famous scientist. She was born in Poland in 1867. She is well-known for her work on radioactivity. When Curie was growing up, she was very interested in science. She loved reading books about physics and chemistry. She wanted to know how things worked. At the age of 24, she went to Paris to study at a university. She studied very hard and often spent long hours in the laboratory. Curie and her husband Pierre Curie discovered two new elements — polonium and radium. They worked together in a small laboratory without good equipment. But they never gave up. Their hard work finally paid off. They won the Nobel Prize in Physics in 1903. In Curie's opinion, it is important to be curious and never stop learning. She believed that hard work and dedication can lead to great discoveries. She also encouraged young people to follow their interests. She believed that interest in science is the first step to becoming a good scientist. 1. Where was Marie Curie born? ________________________ 2. How old was Curie when she went to Paris to study? ________________________ 3. What two new elements did Curie and her husband discover? ________________________ 4.
