【编者按】下面的故事虽然带有一些启示性质，但主要是用英语来理解，毕竟我们很少有机会静下心来阅读英文篇章，而这篇故事还算是一气呵通、连贯性强的，希望大家珍惜这次机会。

Once there was a great teacher, and he had many students.【译】从前有一位伟大的老师，他有许多学生。【单词】【解释】teacher - 老师；students - 学生（student的复数形式）。

有一天，一个学生来找他，问道：“我读了很多书，但大部分都忘了。”【译】The student asked the teacher, "I have read a lot of books, but I have forgotten most of them." 【短语】most of... - 大部分；大多数的；绝大多数；例句：Most of the students in the class are girls.（这个班的大部分学生是女孩。）

“读书的目的是什么？”老师反问道。【译】"What is the purpose of reading?" the teacher asked in return. 【单词】purpose - 目的；决心；意图。

老师当时没有立即回答他。【译】The teacher did not immediately answer him at that time. 【短语】at that time - 当时。

几天后，老师给了那个学生一个筛子，那个筛子脏兮兮的，状况很差。【译】A few days later, the teacher gave the student a dirty and poor-conditioned sieve. 【短语】a few days later - 几天后；脏兮兮的 - dirty；状况很差 - poor-conditioned（或in poor condition）。

老师让那个学生用这把筛子去河边取水。【译】The teacher asked the student to go to the nearby river and fetch water using the sieve. 【单词】fetch - 取来；卖得；给（某人）一击；河水 - river.

他走到河边，用筛子装满了水，但走了几步后，筛子里的水都从洞里排了出来。【译】He walked to the river, filled the sieve with water, but after walking a few steps, the water in the sieve drained out through the holes. 【单词】drained - ；排干；喝光；耗尽；洞 - hole.

然后他又来到河边装满筛子。【译】Then he went back to the river and filled the sieve again. 【短语】then - 然后；之后；again - 再次。

他一整天都在做这件事，但没有完成老师交给他的任务。【译】He spent the whole day doing this, but failed to complete the task assigned by his teacher. 【单词】task - 任务；工作；assign - 分配；指定；指派；确定。

他带着满脸愁容回到老师那里，说：“我不能用这个筛子打水。”【译】He returned to the teacher with a sad face and said, "I can't fetch water with this sieve." 【短语】with a sad face - 满脸愁容；不能用 - can't；打水 - fetch water.

老师看着他微笑。【译】The teacher smiled at him. 【短语】looking at him - 看着他；微笑 - smiled.
