There are 55 different clubs, such as sports and music, for them to choose from. They go to their classes every Thursday from 4:40 p.m. to 6:05 p.m. Students really like the soil and hydroponics club (水土栽培社团). In each class, students first learn how to tell plants from one another and how to plant them in the right place. Then, they have 10 minutes to look closely at real plants. At last, they can plant their plants in the school garden! They need to find the best way to plant different plants. For example, strawberries grow well in water while apples love soil (土). “It’s interesting but also difficult,” said 13-year-old Wang Yijie, “In hydroponics (水栽培), different plants need to stay in water with different pH levels (酸碱值). So, I need to make the water right for each plant by adding acid (酸) in different amounts (量). This helped me learn a lot.” 1．When do students go to club activity classes? A．Every Tuesday morning. B．Every Tuesday afternoon. C．Every Thursday morning. D．Every Thursday afternoon. 2．What is Paragraph 2 mainly about? A．Some popular clubs at the school. B．The best way to plant plants. C．What students do in the soil and hydroponics club. D．How students learn to tell plants from each other. 3．What can we learn from Wang’s words? A．Wang doesn’t like this club very much.
