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!

知识笔记：
单词： 1、parcel：包裹，小包；2、airfield ：飞机起降场地；3、Customs House：海关大楼；4、precious：珍贵，宝贵；
音标：/ʌ/：someone，some，other，custom
/ʌ/是元音音标，属于单元音、中元音及短元音，发音时嘴巴张开一半，牙齿分开，舌中部抬起，舌尖和舌端贴在下齿，由喉部推出气流发出短促有力的类似“啊”的音。发音方法：1）嘴巴张开一半左右，牙齿分开，下嘴唇略向下。2）舌中部向硬颚抬起，不要接触到硬颚，舌尖和舌端两侧贴在下。3）双唇向两边平展形成扁平状，震动声带，短促有力推出气流发出/ʌ/音。注意：/ʌ/个短元音，要诀是发音时收小腹，注意与/æ/的区别。
练习感悟：越着急就会不自觉的读得越快，出错也就越多，今天练习的时候按照原音的语速和语调练习，虽然最后跟原音不完全一样，但是明显感觉心里不再那么着急了。
