Instead of 1. (abandon) him, his owner has made him a safe and comfortable barn to live in. And if you stand nearby and listen, you will hear the sound of a bell 2. (come) from 3. smaller horse. Attached to 4. (it) halter (缰绳) is a small, copper-colored bell assisting the blind friend to follow him,

5. you watch them, you'll find the horse with the bell always checking on the blind one, and that the blind horse will listen for the bell and then slowly walk to 6. the other one is, trusting he will not 7. (lead) astray (迷路地). When the horse with the bell returns to the barn each evening, he will stop 8. (frequent) to look back, making sure that the 9. isn't too far behind to hear the bell．

Life does not throw us away just because we are not perfect or because we have problems or challenges. Sometimes we are the blind horse being guided by the little ringing bell of our acquaintances; 10. other times, we are the guide horse, who helps others to find their way.
