dare

1.dare在下面各句里都用作普通的动词。看作及物或不及物都可以：

• He dares to go.
• Does he dare to go?
• He does not dare to go.
• He will dare to go.
• Will he dare to go?
• He will not dare to go.
• He dared to go.
• Did he dare to go?
• He did not dare to go.

dare也可以用作助动词。例如：

• He dare not go.
• Dare he go?
• He dared not（或durst not）go.
• No-one dared go（或dared to go，或durst go）.
• He dare do anything.
• No-one dare go.

在这种用法里注意：1.句子是否定的或者有否定的意味的。2.不定式除了在dared后面以外都没有to。3.用dare而不用dares。4.durst不及dared普通。5.有时dare也指过去的事。例如：He was afraid, and dare not（或daren't）go.

上面所讲的是正常的用法，事实上下面几句也是常见的。

• He dare go.
• I am sure he dare.
• He dares go.
• Does he dare go?
• He does not dare go.
• He is too weak to dare go today.
• He dared go.
• Dared he go?
• He did not dare go.
• No-one dares go.

2.Do you dare to..? Does he dare to...? 等里的dare to...通常有“胆大妄为”的意思。例如：Do you dare to tell such a lie? Dare you（或he等）...？ 通常有“冒险”的意思。例如：Dare you tell the sick old woman that she has only a few days to live? 但How dare you（或he等）...? 却有“胆大妄为”的意思。例如：How dare you say such rude things about him?

3.下面两句意思相同。第一句比第二句普通：

• If he had been warned, he would not have dared to go.
• If he had been warned, he dare not have gone.

4.I dare say（也作I daresay）通常作“我以为”、“在我看来”、“大概”、“或者”等解。例如：His brother, I dare say, is still in town. 和I dare say his brother is still in town. I dare say后面的从句通常省去that。
