8 阅读理解。 My granddaughter, Shari, owns The Berry (莓果) Factory in Sacramento, California, and her mother, Joan, and I were helping with the Valentine"s Day rush. We"d dipped (浸泡) hundreds of berries, arranged gift baskets and packaged orders to be shipped around the country. By the end of the day, the two middle-aged women, Joan and I, were exhausted. Shari didn"t seem tired. That was typical Shari. Though she was very busy, I"d seen her give away berries to everybody -parking attendants, mail carriers and hairdressers."For me?" they would say, bursting into a smile. As a"thank you", Shari took us out for dinner. But there was a 45-minute wait at her favorite restaurant. "No big deal. There"s another place just up the road," she said, driving us there. This time we walked right in. When the waitress came to take our drink orders, Shari reached into her handbag, pulling something out. "I want you to have these," she said, handing the waitress a box of chocolate-dipped strawberries."She will love those berries!" I thought. But the waitress seemed startled. She only let out a "thank you" before grabbing the box and rushing into the kitchen. A few minutes later, the waitress returned with our iced tea."I apologize," she said. "My best friend and I had promised to send each other something every Valentine"s Day. But she passed away last year. I didn"t know how I"d get through this day without her. Then you handed me that box.""I"m so sorry to hear that," said Shari. "It"s not much, but I hope you can enjoy them." "Oh, I will," the waitress said."See, every year we always sent each other the same thing; a box of chocolate-dipped strawberries bought from our favourite store, The Berry Factory." 1. What can be inferred in the first paragraph? A. The Berry Factory is a gift store B. The Berry Factory has few shop clerks C. The Berry Factory has many branches around the country D. The Berry Factory has customers from different parts of the country. 2. Which of the following words can best describe Shari? A. Talkative B. Creative C. Kind-hearted D. Well-known 3. The underlined word "startled" in Paragraph 4 probably means _______. A. shocked B. excited C. tired D. frightened 4. We can learn from the last paragraph that _______. A. the waitress" best friend didn"t like chocolate B. the waitress" best friend broke up with her C. the waitress" best friend worked for Shari D. the waitress" best friend was Shari"s customer
