课文详注 Further notes on the text
1.A slip of the tongue，(标题)说走了嘴，失言。
slip在这里表示“不经心的错误”、“失误”、“疏漏”：
You've made some slips (of the pen) in your report.
你的报告中有一些小错(笔误)。
When he was nervous, he would sometimes make a slip of tongue.
当他紧张时，他有时就会发生口误。
Are you sure that it was just a slip of tongue?
你确信那只是一时口误吗?
2.People will do anything to see a free show…人们总要想尽办法去看不花钱的演出……
anything用于肯定句时表示“不论什么”、“任何事情”，to see a free show表示目的，也可以用for+名词形式：
He will do anything to save his child's life.
他要想尽办法挽救他孩子的生命。

3.When the news got round that a comedy show would be presented at our
local cinema by the P. and U. Bird Seed
Company…当“皮尤”鸟食公司将在我们当地*演出喜剧节目的消息传开后……
(1)when引导的这个时间状语从句中含有一个同位语从句，即the news
that…。由于that引导的同位语从句较长，便与它所修饰的news隔开了，放在谓语动词之后，以免句子头重脚轻。同位语从句中用了被动语态的过去将来时形式。
(2)get round在这里表示消息、谣言等“传开”(也可以用get around/about)：
The word soon got round that there was buried treasure in that cave.
那个洞里有宝藏的消息很快便传开了。

artistes who should have appeared did not come.
那些没能进到场内的人没有必要感到失望，因为很多应该出场的专业演员都没有来。
must+have+过去分词表示对过去发生的事进行推测(其否定式为can't+have+过去分词，cf.第17课语法);need+have+
过去分词表示过去不必做但实际已做了的事(cf.第41课语法);should/ought
to+have+过去分词表示本来应该做而实际未做的事(cf.第65课语法)：

5.As soon as he opened his mouth, everyone burst out laughing.

burst out为固定短语，其含义之一为“突然……起来”，后面通常接动名词，也可以接in/into+名词：

6.We all know what the poor man should have said, but what he actually said

用should+have+过去分词表示过去应当做而并没有做的事时，它后面经常跟but(actually)以形成对比：
