练习材料：Lesson 7 Too late
The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamonds from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand!

练习感悟：今天换了一种跟读的方法，先一直跟，到感觉熟悉了在录自己的，重复的次数多了一些，似乎对于长句子的练习有帮助，可以继续尝试，也发现了自己读和听起来不一样，还是要有对照反馈才能知道自己的问题。今天早上注意到at the door，opened the parcel这两个次音频中似乎用了连读，用轻读带过去，自己掌握的还不够熟练。以及在语调方面，以前自己只会记一下这个词要升还是要降，但是仔细听词中不同音节也有区别，需要注意。不知不觉读了七天了，时间真快啊。
