June 拓展思考（示例） Part 1 Zhangye Geopark is famous for its colourful rainbow hills. The hills look like waves and have many bright colours. They were formed when rivers brought coloured sand and stones into a lake, and later the land rose and was shaped by wind and rain. The best time to visit is from June to September when the weather is cool in the morning and evening. I think it is amazing because the colours look like a painting on the ground. Part 2 I recommend you to visit Zhangye Geopark in summer. You can see hills that look like rainbows painted on the earth. The colours are most beautiful after a summer rain when the sun shines. The best season is from June to September because the weather is pleasant. You will be amazed by the natural beauty. Part 3 The writer uses words like “must” and “should” to persuade readers to visit the park. They make the reader feel that this is a special place they should not miss. For example, “you must visit” suggests that the experience is necessary for nature lovers. This helps the writer encourage action and create excitement. Using such strong words is an effective way to persuade. 1 学科网（北京）股份有限公司 $
