老师：

A young man，while traveling through a desert，came across a spring of clear water．The water was sweet．

He filled his leather container so that he could bring some back to an elder who had been his teacher．

After a four-day journey，the young man presented the water to the old man.

His teacher took a deep drink，smiled warmly，and thanked his student very much for the sweet water.

The young man went home with a happy heart．

After the student left，the teacher let （another/other）student taste the water.  He spit it out，saying it was awful．Apparently，it was no longer fresh because of the old leather container．

He asked his teacher，"Sir，the water was awful．Why did you pretend to like it？"

The teacher replied，"You tasted the water．I tasted the gift．The water was simply the container

for an act of kindness and love．Nothing could be sweeter．"

We understand this lesson best （as/when）we receive gifts of love from children．

Whether it is a cheap pipe or a diamond necklace，the proper response is appreciation．We love the idea within the gift rather than the thing．

（1）答案是another, 可是other为什么不可以呢？答案是when, 可是as难道不可以吗？

（2）he could bring some back to an elder who had been his teacher. - 这里的had been暗示当时已经不是他的老师了吗？不然，为什么不用一般过去时was呢？很奇怪。

谢谢老师！
