Lesson 9 A cold welcome
On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing.
任务配置：L0+L4
知识笔记：at five to twelve 差五分钟12点，学了一个新表述，以前都是eleven fifty-five。。。
练习感悟：后面这几篇文章越来越难了。。果然是要一步一步来。前面的不能过急，决不能读一遍了事。要努力背下来才是正理！
