| My sister is twenty-two this year. She is now a worker in a factory (工厂). The factory is far from our home, so she gets up early every morning, and then she goes to work by bus. At about seven thirty, she gets to the factory. She works very hard. Everyone likes her very much and says she is a good worker. She has lunch in the factory. She often plays table tennis after lunch. In the evening, she learns English at home. Her English is very good. She sometimes helps me with my English. I like her very much. | ||||||||||
