pray
1.下面各句里的pray都可以改作please：
- Pray let me know.
- Do pray let me know.
- Do, pray, let me know.
- Pray don't let me disturb you.
- Pray(,) what do you mean by that?
- What do you mean by that(,) pray?
- Let me know(,) pray!
但pray跟please的语法结构完全不同：pray=I pray（我请求）或=I pray you（我请求你）。参见please(d) 1，4和6
2.比较下面两句：
- I pray you, let me know.
- I pray you let me know.
在第一句里you后面有逗号，you当然是pray的宾语，let当然是祈使句。在第二句里you后面没逗号，全句的语法结构就可能有三种说法：（1）跟第一句相同，（2）let是没有to的不定式，（3）you let me know是名词从句，作pray的宾语。
