2. twin是指“双胞胎”还是指“双胞胎之一”
Theso much alike that I can’t tell which is which.
A. twin looks B. twins lookC. twin lookD. twins looks
此题容易误选C，误认为twin的意思是“双胞胎”，指两个，表复数意义。其实，此题的正确答案为B，twin的意思是“孪生子之一”或“双胞胎之一”，英文解释为either of two children born of the same mother at the same time，即它指的是两者中的一个，而不是两个，要表示双胞胎，要用复数twins。类似地，parent的意思是“父（母）亲，父亲或母亲”，其英文解释是the father or mother of a person or animal。要表示“父母双亲”，要用复数parents。如：Where are your parents?你父母在哪儿？Denise and Martin have recently become parents.丹尼斯和马丁最近当爸爸妈妈了。Being a parent can be hard work.为人父母是件很辛苦的事。To have good children one must be a good parent.要想培育出好的孩子，自己必须要是好的父母。
