四年级英语小故事150字，最好带翻译。

A mother and her young son get into a bus. The bus conductor(售票员) comes to them for their money.The mother says,”I want a ticket(票) to Shanghai”,and gives her 5 yuan.The conductor looks at the boy,and says to him：”How old are you,young man”The mother begins to say,but the conductor stops her and the boy says,”I’m 4 at home,and 2 in buses.”The mother has to give 2.5yuan to the conductor. 一位母亲和他的儿子上了一辆公交车，售票员来到他们身边让他们买票。母亲说：“我想要一张去上海的票。”然后给了售票员5元钱。售票员看了看那个男孩，对他说：“年轻人，你多大了？”那位母亲刚想开口就被售票员打断了，然后那个男孩说：“我在家是4岁，在车上是2岁。”那位母亲只好又付了2.5元给售票员。是个小笑话，应该只有Conductor一个字你不认识，发音没办法表示出来，可以查一下字典~希望帮得上你的忙^_^
