练习材料： L16-1：Mary had a little lamb 时长：45s
Mary and her husband Dimitri lived in the tiny village of Perachora in southern Greece.
One of Mary's prize possessions was a little white lamb which her husband had given her.
She kept it tied to a tree in a field during the day and went to fetch it every evening.
One evening, however, the lamb was missing.
The rope had been cut, so it was obvious that the lamb had been stolen.
When Dimitri came in from fields, his wife told him what had happened.
Dimitri at once set out to find the thief.
He knew it would not prove difficult in such a small village.

练习感悟： 看起来很简单，读起来却不简单，一开始总觉得应该15分钟内可以搞定，但是读了一遍又一遍，总有一些地方不满意，重新读，这样子30分钟就过去啦
第二句不知道为什么总是会卡壳， prize possessions 是首字母相同的单词 little white lamb 应该是要嘴巴张大的比较夸张，读起来也会费劲一些。
在家里的话不应该把任务截成两段完成，总是拖延，上午完成了一部分，下午的另一部分就拖到第二天了，已经连续拖了好几天，中间也短了4天没有读，内心很惭愧啊
