please(d)
1.注意下面四句的结构：
- Please let me know.
- Please to let me know.
- Will you please let me know?
- Will you please let me know.
第一句比第二句普通得多，第二句是旧式，现在只有“老派”的人用它。第一句和第二句都不及第三句客气。第四句的末尾用句号，因为全句在语法上虽然是疑问句而在作用上等于请求句，所以用句号也可以。第三句和第四句里的please后面加上to也可以，但现在一般不用to。
Please let me know的强势式是Do please let me know。
2.决不可用Please you...，如不可说Please you let me know，该把you删去。Please you...在15和16世纪里是用的，但现在绝对不可用。
3.关于Please kindly...，参见kindly 2
4.说“请不要…”用Please don't..., Please do not..., Please not to...和Don't please...都可以，似乎第四种表达方式最不普通。
5.下面各句里please后面的不定式有to或没有to都可以：
- We ask you to please (to) send the goods immediately.
- The members will please (to) leave their addresses with the secretary.
- If you will please (to) look into the matter at once, we shall be very much obliged.
6.We ask you to please to send the goods immediately和We ask you to please send the goods immediately里的to please都是不定式。也可以说We ask you please to send the goods immediately，这句里的please不是不定式而是祈使句，它的前面和后面可以加上逗号。
下面各句里的please也都是祈使语：
- Please(,) may I take this chair?
- May I take this chair(,) please?
- Please(,) can you tell me more?
- Can you tell me more(,) please?
- Don't(,) please(,) come here.
- If so, may we(,) please(,) have an explanation?
Will you please let me know?和Will you please let me know（参见1）里的please通常不被当作祈使句，它的前面和后面不用逗号。但Please(,) will you let me know和Will you let me know(,) please里的please都是祈使句。
7.Those who would like to go to the pictures this evening please signify in the usual manner里的please是祈使句，那Those可以算作呼唤语。
8.much pleased, very much pleased和very pleased都可以说，但有些英美人以为第三种表达方式是不正当的。
9.说“乐于…”在pleased后面接不定式。例如：I shall be pleased to see you.和She was pleased to be witty.说“因…而快乐”在pleased后面接不定式或at和动名词都可以，如I was pleased to hear of his success和I was pleased at hearing of his success。
10.if you please往往有“竟然”、“出人意料”、“岂有此理”等意思，例如：
- I thought I had lost my pen, which, if you please, was in my pocket all the time.
- Instead of paying me the money he owed me, he wanted me to lend him more, if you please!
11.关于a pleased laugh（一个愉快的笑声）等，参见much 3 (5) E
