小刘：谢谢。我自己也没想到。一下子怀上了两个，真的很惊喜。
心涛：你知道吗，我家也有多胞胎的基因。我爸爸和我叔叔是同卵双胞胎，我两个姑姑是异卵双胞胎。
小刘：是嘛!真有意思。
心涛：这还不算什么。我妈妈和我两位阿姨是三胞胎姐妹，我小姨又生了一男一女的龙凤胎!
小刘：哇，你们真是多胞胎家族啊!那你呢?你有同胞兄弟姐妹吗?
心涛：不瞒你说，我有一个哥哥一个姐姐和一个妹妹，我们可是同一天出生的!
小刘：哈!也就是说你妈妈生了四胞胎啊!
心涛：对啊，看着别人都是独生子女，我却有三个兄弟姐妹，这感觉，甭提有多幸福了!
Xintao: Congratulations! Xiao Liu, I heard you’re pregnant with twins.
Xiao Liu: Thank you. I didn't expect that. It’s surprising to carry two babies at a time.
Xintao: You know what? There is a gene of multiple births in my family. My father and my uncle are identical twins and my two aunts are fraternal twins.
Xiao Liu: Really? That’s interesting.
Xintao: That’s not a big deal. My mother and my two aunts are triplets and another aunt of mine gave birth to a boy and a girl.
Xiao Liu: Wow. You really have a multi-births family. How about you? Do you have any siblings?
Xintao: To be honest, I have an elder brother, an elder sister and a younger sister. We were born on the same day!
Xiao Liu: Wow! That means your mother had quadruplets, didn't she?
Xintao: Exactly! It’s amazing that others are only child of their own family while I have three siblings!
