课文详注 Further notes on the text
1．ask for trouble
You shouldn't have been so rude to her. You are asking for trouble.
The boss seems to be annoyed. To talk to him now is to ask for trouble.
2．I don't think the windows need cleaning at this time of the night.
（1）有些动词如 think, believe, expect, suppose 等后面跟表示否定意思的宾语从句时，否定词not 往往用在主句中，但译成汉语时否定意义应在宾语从句中。我们一般不说 I think
Mary won't come this evening，而说 I don't think Mary will come this evening。又如：
I don't believe he is still in London.
（2）need cleaning 的含义相当于 need to be cleaned。need 表示“需要”时，后面接的动名词有被动的含义（cf．第44课语法）：
The needs mending.
2．I immediately regretted answering in the way I did.
I regretted saying it almost at once.
We regret to inform you that you needn't come here next week.
与 regret 相似，remember, forget, stop 等动词后面接不定式与接动名词形式的意义有很大不同。 remember / forget+不定式指未来的动作（或从过去观点看的“未来的”举动）：
Remember to post the letters.
I remembered to post the letters.
Don't forget to ask Tom.
I forgot to ask Tom.
remember / forget+ 动名词形式则指过去的动作（已发生过）：
I remember posting / having posted the letters.
Have you forgotten meeting / having met her at a party?
On the way to the station I stopped to buy a paper.
When he told us the story, we just couldn't stop laughing.
词汇学习 Word study
The policeman answered in a tone.
The waiter greeted us in a friendly tone.
You should use the rising / falling tone at the end of this sentence.
Her dress has a bright tone.
The building has a foreign tone.
2．用于并列补充句和反应句的 so与 neither／nor
so和 neither／nor 用于并列补充句和表示反应的句子时表示“也”、“同样”， so 用于肯定句，neither ／nor 用于否定句（neither 和 nor完全可以互换）。它们后面跟的是省略形式的分句，只有助动词+ 主语，也可以是情态助动词 +主语：
You should work less and so should I.
You shouldn't work so hard and nor should I.
I've got a new car and so has John.
She's going to help us and so is Jim.
He likes his beer and so does Frank.
