1949年3月23日上午，***率中共中央机关离开西柏坡前往北平。出发时，***回过头来对周恩来说，今天是进京的日子，进京赶考去。“进京赶考”意味着什么（　　）

    Mrs. Green doesn't like sports. She has much work to do at home. Her mother is coming this afternoon and she goes to meet her. Near the school she looks at her watch. She has some time. So she goes into the school. Her son isn't in the classroom. She asks a boy and knows they're behind the school. She sees some boys playing there. Her son is there too. She watches them playing and soon she's angry. She takes her son to the wall. “Go home with me, Richard.” She says, "Don't play with them. I can buy a nice ball for you. Then you don't need to scramble for the ball."
