Meaning: Some things are not as valuable as they appear to be.

　　汉语中意思接近的有：金玉其外，败絮其中；闪闪发光物，未必尽黄金。

　　描述要点：先要描述表面上看起来非常好或非常有价值的东西，然后通过有代表性的细节，揭示这一东西的实质其实是与它留给你的表面印象不相符。

　　Decide which of the two versions given below you think is the better one. Why?

　　I have a very little dog named Lili, she is only half a year old. One day, I took her out to go walking. We met a dog as large as a goat. Lili felt nervous at the sight of that big dog. That dog stepped closer and closer to her. There was no time for her to run away. Lili had to bark in top voice to that dog. The strangest thing happened, it was that big dog who was scared and ran away with the tail downward. It turned out that dogs are not as strong as they look to be.

　　Version B

　　My little dog is only six months old; her name is Lili. We went out for a stroll one day and met a dog big as a goat. I could feel Lili grew more and more frightened as the big dog drew closer and closer. Because there was no chance to run away and escape, she barked at him as loudly as she could. Then, strange as it may seem, it was that big dog that turned and ran way with his tail between his legs. So it appears that dogs are not so fearsome as they may look.

　　注解：

　　stroll: a slow, relaxed walk漫步，闲逛

　　draw: to move slowly or continuously (缓慢、持续地)移动

　　fearsome: frightening可怕的
