五、不定式结构作状语
不定式结构可以作状语，修饰动词、形容词、副词等，表示目 的、原因、结果、条件等。 1．表示目的： They ran over to welcome the delegates. He bought a bicycle to go to town more quickly. He went home to see his mother. 注①：不定式结构表示目的时，通常句子的主语就是它的逻辑主语 (参见以上三句)，但也有例外的情况，例如： I stopped for him to speak to me. He opened the door for the children to come in. He brought a porter to carry the boxes / bags. They sent a man to mend the window. He stood up to be seen better.
பைடு நூலகம்
四、不定式结构作定语 1．不定式作定语通常只能放在被修饰的名词之后，如： It’s time to go to bed. He is not a man to bow before difficulties. Have you anything to declare? She usually has a lot of meetings to attend in the evening. I want to get something to read during the vocation. 2．能带不定式结构作宾语的动词，转化成名词时往往也能带不定 式结构作定语，如： I don’t wish to quarrel with you. →I have no wish to quarrel with you. They will attempt to cross the river tonight. → They will make another attempt to cross the river tonight. She promised not to do that again. → She made a promise not to do that again.
