    Just up the road from my home is a field，with two horses in it. From a distance，each horse looks like any other horse. But if you get a{#blank#}1{#/blank#}(close)look, you will notice one of them is blind. Instead of abandoning 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 {#blank#}2{#/blank#} (come) from{#blank#}3{#/blank#} smaller horse. Attached to{#blank#}4{#/blank#}(it) halter is a small, copper-colored bell assisting the blind friend to follow him.

    {#blank#}5{#/blank#} 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 {#blank#}6{#/blank#}the other one is，{#blank#}7{#/blank#}(trust ) he will not {#blank#}8{#/blank#} (lead) astray (歧路). When the horse with the bell returns to the barn each evening，he will stop {#blank#}9{#/blank#}(frequent) to look back，making sure that the other isn't too far behind to hear the bell.

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

    When I was a kid, Mom used to cook food for us. One night after {#blank#}1{#/blank#} (spend) a long hard day at work, Mom placed a plate of bread jam and {#blank#}2{#/blank#} (extreme) burnt toast（烤面包） in front of my dad, I was waiting {#blank#}3{#/blank#} (see) if he noticed it. However, while eating his toast. Dad just asked me {#blank#}4{#/blank#} my day was at school. I don't remember what I told him that night,{#blank#}5{#/blank#} I do remember I heard Mom apologizing to Dad for burning the toast. I'll never forget what Dad said, "Honey, I love burnt toast."

    Later that night, I {#blank#}6{#/blank#} (go) to kiss Daddy good night and asked him if he really liked his toast burned. He gave me {#blank#}7{#/blank#} big hug and said, "Your mamma put in a long hard day at work today, really {#blank#}8{#/blank#} (tire). Besides, a burnt toast never hurts but cold words do!"

    What I've learned over the years {#blank#}9{#/blank#} (be) that learning to accept each other's faults is one of the most important {#blank#}10{#/blank#} (key) to creating a healthy, growing and lasting relationship.
