练习材料：
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+L1
知识点：
The clock has stopped!
现在完成时态，说话的人是在当时的“现在”说的，所以是现在时间；主语是the clock，所以用has，因为在观众看来，时钟时自己停下来的，文章中也没有其他信息指出它是“被停下”的，所以使用主动语态，stop，但是在那个人说话之前，始终就已经停止了，所以用stopped。
练习感悟：
新概念第二本相对容易一些，慢慢上手学习语法知识，手上有语法知识书，日拱一卒。
