“You must be mad！” said my friends. “Giving up your job now， when there isn't much chance of finding another one， ever！”
But I had already come to my lonely decision. To wake up in the morning with a sense of fear， to force a hasty breakfast down an unwilling throat and then to set off for work with pounding heart and frozen face had become habitual， and I had turned to tranquilizers(镇定剂) to help me along.
It hadn't always been as bad as this. Ten years before I had managed quite well.
I， in common with most other teachers， am rather selfcritical， and I knew now I was no longer “managing”.My classes were noisy， the children were not learning very much， and my attempts to cope with changing teaching methods produced very little effect. At one time my very presence in the doorway would be enough to ensure a partial silence. Now they give a vague(含糊的) “Hello， Miss”， and carry on. I had run out of enjoyment and enthusiasm. It was time to stop.
Was it all my own failure？ In fairness to myself， I don't think it was. I had plenty of ideas， I loved my subject， and I liked children.
I had been idealistic. But the reality I faced was bored children， overstimulated(刺激)by videowatching the night before and tired out by a late bedtime. They were given the wrong food at the wrong time， who came without breakfast to school and then stuffed themselves with gum and chocolates bought on the way； who were “high” with hunger in class and talked restlessly as the cooking smell from the school kitchen came drifting (漂) to all floors.
I had been trying to create the basic conditions in which teaching becomes possible， but I had failed， and no longer had the stomach for the job.
