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!

任务配置：L0+L1+L4

知识笔记：

1.朗读(L0): 提交录音的时长为54秒，原音正文部分55秒左右。

2. 音标(L1):  plane /pleɪn/ late /leɪt/ all /ɔːl/ valuable /ˈvæljʊəbl/ parcel/ˈpɑːsl/ earlier /ˈɜːlɪə/ police /pəˈliːs/  steal /stiːl/ building   /ˈbɪldɪŋ/ while /waɪl/ airfield /ˈeəfiːld/ full /fʊl/

L /l/

1）双唇略张开，牙齿自然张开。

2）舌尖紧贴上齿龈，舌前部抬起靠近硬腭。

3）气流从舌的两侧泄出，声带震动发音。

/l/发音有两种情况，根据它所出现在音节的位置不同发出两种不一样的音。/l/在音节的音头时，发音时舌头从上齿龈迅速下落，为清晰音；当其在音尾时靠舌头抬起使音从两侧发出，为含糊音。

3. 今天是第七天: 今天的感悟是 /ə/一直以来读得都是靠中央了，导致遇到有这个音时一直都很拧巴，口形僵硬。/ə/是唇形和舌位最放松的音标。发音的时候，双颌微微打开，双唇放松，舌尖放在一早醒来最自然的位置，声带振动自然发声。这个音只有放松了才能发得好，同时也是所有元音弱化后的音。
