Don’t ever tell anybody anything. If you do, you start missing everybody.” “说来好笑。你千万别跟任何人谈任何事情。你只要一谈起，就会开始想念每一个人。”——《麦田里的守望者》(The Catcher in the Rye)，J.D. Salinger “Whatever our struggles and triumphs, however we may suffer them, all too soon they bleed into a wash, just like watery ink on paper.” “无论是怎样的奋斗和成功，无论我们遭受何等的痛苦和磨砺，一切都会很快渗入浪涛中，就像水墨颜料泼洒在纸上。”——《艺伎回忆录》(Memoirs of a Geisha)，Arthur Golden . 28 主题写作 Caught in a flood (Part II) After a brief discussion, Mum and Dad decided they should stay in the house. They thought it would be really dangerous to try to walk through the water to get to higher ground. “Mary, we’ll have to go upstairs and wait there,” said Mum. “OK, Mum. If that’s what you think is best,” Mary replied uncertainly. So they went upstairs and waited. Downstairs, water started flooding into the living room and kitchen. All three of them were nervous, but at least they had disaster supplies, including food and drinking water. . 29 主题写作 Finally, the rain stopped, but Mary and her family could not leave while the house was still flooded. They listened to the radio and learnt that rescue workers in boats were coming to rescue people who were trapped in their homes. They waited for a boat to arrive at their house.
