She's such a goody two-shoes that all the men I know are afraid to ask her out on a date.
尽管有些学者认为goody two-shoes的复数形式应该是goodies two-shoes或goody two-shoeses，但词典推荐的用法是单复数同形（同为goody two-shoes）。
Kevin:I think Penny is a nice girl, modest and elegant.
Rose:She is not as nice as you see.
Kevin:Make it clear.
Rose: She is always to pretend to be a goody two-shoes when she goes out with his friend and another person when she is at home.
