The best spear(矛) and the best shield(盾)
导读：同学们，前几个单元我们读了许多和动物有关的寓言故事。这个单元我们来读一个出自《韩非子》的寓言故事，看看你们能不能猜出由这个故事引申而来的成语是什么。
A man of the State of Chu(楚国) had a spear and a shield for sale(出售).
He held up his shield and said loudly in praise of his shield, “My shield is strong. Nothing can pierce(刺穿) it through.”

Then he held up his spear and also said in praise of his spear, “My spear is very sharp. It can pierce through anything.”
When the people heard this, they laughed loudly.
One of them asked him, “According to(根据) what you said, your spear is the sharpest and your shield is also the strongest. Then what would happen if you use your spear to pierce your shield?”
The man was embarrassed(窘迫的). He did not say a single word and left quickly.

“中华传统”译文：
楚国有个人在卖一支矛和一面盾。
他举起盾，大声夸道：“我的盾坚固无比，没有任何东西能刺穿它。”
然后又举起矛，大言不惭地说道：“我的矛锐利无比，能够刺穿任何东西。”
一旁的人群听到他的话，大笑起来。
其中一个人问他：“照你这么说，你的矛是最锋利的，你的盾也是最坚固的。那么用你的矛来刺你的盾会怎么样呢？”
这人非常窘迫，哑口无言，匆匆离开了。

1. 自相矛盾
2. Because he said nothing could pierce his shield, but his spear could pierce through anything. His words were contradictory, and he couldn't answer people's question.

1. 该寓言是《韩非子》中的经典故事，引申出的成语是自相矛盾。2. 这个人同时吹嘘自己的盾坚不可破、矛无坚不摧，两种说法相互矛盾，面对旁人的质问，他无法给出合理的回答，因此感到窘迫。
