重点解说：

★ 像MacCornick, McCarthy这般，在姓氏前冠上Mac或Mc(意为~之子)时，意味着此人为爱尔兰或苏格兰人的后裔。

★ happen to ~「碰巧~，刚好~」一语用于表示某种状况是在无意之中发生的。Do you happen to have an extra copy of this textbook?「你刚好有多余的一本教科书吗？」 I happened to meet Mary.「我碰巧遇见了玛丽。」这句话也可以说成I came across Mary.或I ran into Mary.

★ It's a small world.「世界可真小。」这句话常用于意外在某地遇到熟人时。
