Lesson55 Not a gold mine
Dreams of finding lost treasure almost came true recently. A new machine called 'The Revealer' has been invented and it has been used to detect gold which has been buried in the ground. The machine was used in a cave near the seashore where--it is said--pirates used to hide gold. The pirates would often bury gold in the cave and then fail to collect it. Armed with the new machine, a search party went into the cave hoping to find buried treasure. The leader of the party was examining the soil near the entrance to the cave when the machine showed that there was gold under the ground. Very excited, the party dug a hole two feet deep. They finally found a small gold coin which was almost worthless. The party then searched the whole cave thoroughly but did not find anything except an empty tin trunk. In spite of this, many people are confident that 'The Revealer' may reveal something of value fairly soon.

如何正确的发出/j/这个音。
1）双唇向两旁伸展成扁平形。
2）舌前部向硬腭尽量抬起，不要抵住硬腭。
3）气流从舌和硬腭的缝隙间通过，同时声带需震动，发音短促，立刻向后面的元音滑动。
注意：/j/是个半元音，发音时口型和元音/iː/有点相似，但它仍是个辅音，元音可以单独成音可以延长，半元音不可以单独成音不可以延长。
相关单词：used，new，value
