1. She is __________ t get an ffer(第一个拿到ffer的毕业生) in the big cmpany.2. He is _____________（唯一幸存的人） the accident. 3. He is______________ the jb. （合适做这份工作的人）
二、名词被特定词修饰当名词被序数词或 the nly, the next, the last, the right，形容词最高级修饰，且该名词是作定语的非谓语动词的执行者时，用不定式主动形式作定语。
不定式作后置定语的几种情况

1. I have a lt f things t d tmrrw.2. Please give me smething t drink.3. He will shw yu the right path t take.
在一些固定句型中，动词不定式作定语用主动形式表被动意义，如 have / get / give / shw sth t d。在此类句型中，不定式与前面的名词构成动宾关系，和句中另一个名词或代词构成主谓关系。 I d a lt f things. / I drink smething. / Yu take the right path.
1. D yu have any clthes t wash?2. Kids, d yu have any clthes t be washed?3. I can’t g ut this afternn, because I have many materials t type. 4. The bss tld me that he had many materials t be typed.
当不定式与前面的名词构成动宾关系，且和句中的主语构成逻辑上的主谓关系时，用主动形式表被动意义；若没有逻辑上的主谓关系且不确定逻辑主语是谁时，仍用被动语态。

t/in rder t/s as t
目的状语从句与不定式的转换

①当目的状语从句中的主语与主句中的主语相同时，可以直接简化为不定式或不定式短语作状语。
②当目的状语从句中的主语与主句中的主语不相同时，要用动词不定式的复合结构作状语。
