误：He went to bed until 11 o’clock in the evening. 正：He didn’t go to bed until 11 o’clock in the evening.
解析：until意为“直到??为止” “到??时”可用作介词，后跟名词或名词短语，也可用作连词，后跟句子。until用于否定句中时，主句的谓语动词通常为非延续性动词（go, come, get, arrive, leave等），如：

until用于肯定句中时，主句的谓语动词通常为延续性动词（live, work, study等），表示该动作一直持续到所表示的时间。如： We’ll wait until she comes back. 我们会一直等到她回来。

2)用作形容词词组，修饰不可数名词。如：
I don’t like winter because there’s too much snow and ice.
我不喜欢冬天，因为雪和冰太多。 3)用作副词词组，修饰动词。如： Don’t speak too much. 别讲得太多。
much too意为“太”、“非常”，用作副词词组，修饰形容词或其他副词。如： It’s much too cold today. 今天天气太冷。
The old man walked much too slow. 这位老人走得太慢了。
注意：两者都可以用作副词词组，但too much不可修饰形容词， much too 不可以修饰动词。 [课文要点] I have too much homework this weekend. (P66)

He replied that he didn’t know the secret. 他回答说，他不知道这个秘密。
answer用作及物动词，作“回答”解，但answer可跟名词、代词或从句。如： He answered nothing. 他什么也没有回答。 I can’t answer you now. 我现在不能回答你。
