John and his father never agree on one thing, so they often disapprove［1］of each other, for there was some misunderstanding［2］ between them. Once, John and his parents went to his aunt’s home for dinner. When they left after dinner, John said “Bye-bye!” to his aunt in a low voice. However, his father didn’t hear it and he thought John misbehaved［3］ himself for it was impolite［4］to leave without saying goodbye. John insisted that he did say it, but his father didn’t listen to him. From then on, John was unfriendly［5］ to his father, which made his father extremely unhappy［6］.

Undoubtedly［7］, it is unwise ［8］of John to do so. After all, they are father and son. His father sent him to a class of manners to enrich［9］ his knowledge of manners, which his father believed would enable［10］him to be a good-mannered boy. John’s father said he was angry at his son’s dishonesty［11］, which would certainly endanger［12］ his future. His father’s nonstop［13］nonsense caused John much discomfort［14］. John had to go to the class. Later on, he did everything against his father’s will.

汉语译文：约翰和父亲总有分歧，所以他们经常不赞同对方的想法，因为他们之间有一些误会。一次，约翰和父母去姑姑家吃饭。晚饭后当他们离开时，约翰小声对姑姑说“再见!” 然而，他的父亲没听到，他认为约翰不懂规矩,不告而别是非常不礼貌的。约翰坚持说他确实说了，但他父亲不听。从此，约翰对父亲很不友善，这使他的父亲非常不高兴。

毫无疑问，约翰这样做是不明智的。毕竟，他们是父子。他的父亲把他送去上礼仪班以丰富他的礼仪知识，他的父亲认为这样做会使他成为一个懂礼貌的男孩。约翰的父亲说对于儿子的不诚实他感到很生气，他的不诚实当然会危及他的未来。父亲不间断的唠叨让约翰很不舒服。约翰不得不去上课。此后，他总是和父亲对着干。
