Miss Green was sad. She took her favourite orchid(兰花)to school to show her students. She left the flower in the classroom, but later it was gone. Three students were still in the room. (One of them must be the thief(小偷).
Two of her students, Max and Nina, decided to help her find who did it.
The first student they talked to was Maria. "I have a cold," she said." I cannot even speak."
Patrick was standing next to Maria. "Megan and Maria had already been in the room when I arrived," he said quickly. "I didn't see the orchid."
Megan, who was known to love pretty flowers best, was the next to answer their questions.
"Of course it wasn't me," she said to Max and Nina. "I have two orchids at home. I just stopped by to put a book on my desk. Maria was already in the room."
"So how can you explain that, Maria?" Nina asked.
"After I practised singing, I stopped to get my notebook, "Maria whispered(小声说). "I'll have a concert tomorrow. I didn't take the orchid."
Nina and Max had a quick conversation with Miss Green and said, "We think we know who took the orchid."
