问题 There are no hard and fast rules, but rather traditional guidelines as to who pays for what. The underlined part means______.
选项 A、fixed
B、difficult
C、single
D、plain
答案 A
解析 习语理解题。原句中hard and fast是习惯用语，意为“(规则等)不能变通的，不容更改的”，而fixed意为“固定的，不更改的”，两者意思相同，因此选项[A]为答案。difficult意为“困难的”；single意为“单一的；单身的”；plain意为“简单的；平的”，均与句意不符，故排除。
