A kid said to his dad,Pop, my leacher asked me if I had any younger siblings1 who will be coming to school.
The dad teplied, What did your teacher say when you told him you are an only child?
The kid answered, He said, Thank goodness!
一个孩子告诉他父亲:爸，我的老师问我,有没弟弟或妹妹将要去上学的。
父亲回答说:当你对你说的老师你是独生子时，他怎么说?
孩子回答:他说谢天谢地!
if若接在ask, doubt, know, tell, try, wonder等动词的后面,则表示是不是的意思。
an only child是表示家里惟一的孩子，无兄弟姐妹,而the only son则是表示家里惟一的儿子或女儿,有其他兄弟或姐妹。
goodness在这里当感叹词,表示惊讶、愤怒或诅咒所发出的感叹，如:My goodness!=My God!。句中若有两个引号,则里面一层用单引号,外面一层用双引号。
sibling2 [srblm]n.兄弟姐妹
goodness [ gudnts]n.God的委婉语
