vi. 叛逃（defect的过去式与过去分词形式）

defect，fault

【解说】

这两个词都有“缺点，缺陷”的意思。它们的区别是defect强调不影响全局，完美不足，而fault强调不十分严重，无伤大雅；用于人时，defect多指人体器官上的缺陷，而fault多指道德行为的缺点；用于物时，defect指易于察觉的缺陷，fault则指功能方面的缺陷。例如He has some defects in his eyesight.他的视力有缺陷。I bought the cloth cheap because there is a small defect in it.这布我买得便宜，因为上面有个小疵点。Snobbishness was his main fault.他的主要缺点是势利眼。I don't mean to praise myself.I have my fault.我并不是要表扬自己，我也有我的过错。His only fault is that he lacks ambition他唯一缺点就是没有雄心壮志。This accident is due to a fault in the electrical circuit.这次事故是由电路故障引起的。There is a fault in the machine.这机器有毛病。
