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!

任務配置：L0+L1+L4

知識筆記：

1.朗讀(L0): 提交錄音的時長為54秒，原音正文部分55秒左右。

2. 音標(L1):? plane?/ple?n/?late?/le?t/?all?/??l/?valuable?/?v?lj??bl/?parcel/?pɑ?sl/ earlier?/???l??/?police?/p??li?s/??steal?/sti?l/?building? ?/?b?ld??/?while?/wa?l/?airfield /?e?fi?ld/?full?/f?l/

L /l/

1）雙唇略張開，牙齒自然張開。

2）舌尖緊貼上齒齦，舌前部抬起靠近硬腭。

3）氣流從舌的兩側泄出，聲帶震動發(fā)音。

/l/發(fā)音有兩種情況，根據(jù)它所出現(xiàn)在音節(jié)的位置不同發(fā)出兩種不一樣的音。/l/在音節(jié)的音頭時，發(fā)音時舌頭從上齒齦迅速下落，為清晰音；當其在音尾時靠舌頭抬起使音從兩側發(fā)出，為含糊音。

3. 今天是第七天: 今天的感悟是 /?/一直以來讀得都是靠中央了，導致遇到有這個音時一直都很擰巴，口形僵硬。/?/是唇形和舌位最放松的音標。發(fā)音的時候，雙頜微微打開，雙唇放松，舌尖放在一早醒來最自然的位置，聲帶振動自然發(fā)聲。這個音只有放松了才能發(fā)得好，同時也是所有元音弱化后的音。
