Summary: 1. 不定式的结构：________________ 2. 分析上面的句子，我们知道在描述太空探索时，动词不定式不仅可以用来表______，还可以用来作_______，表_______。
不定式作定语，一般放在被修饰的名词、代词后面。例如：
只能用动词不定式做定语的情况
例：1. Please make an effrt t catch the bus.2. He made a prmise t cme here n time tmrrw.
1.当修饰的名词是ability, ambitin, attempt, chance, curage, desire, decisin, effrt, failure, mment, prmise, right, time, wish … （一些表示企图、努力、愿望、打算、能力 等意义的名词）
例：1. He was the first ne t think f the idea.2. Yu are the nly persn t be late.3. The manager is the last t cme t the meeting.
2.当修饰的名词前有the nly, the next, the best, the first, the last,以及由序数词或形容词最高级修饰的名词常常用不定式作定语。
例：1. D yu have anything t say?2. There is nthing t wrry abut.3. I want t get smething t drink.
3.当修饰的词为smething, nthing, anything等不定代词时。
4.当定语表示未来的还没做的动作时。
例：The letter t be written is t my father.The matter t be discussed is imprtant.
不定式作状语，用来修饰动词、形容词和副词。
例：I cme here t say gd-bye t yu.S as nt t disturb the baby, I walked quietly.
常用结构：t d; in rder t d, s as t d, s/ such…as t d, etc.
※ 不定式作目的状语时， 其动作通常迟于谓语动词 的动作。
例：I said that t encurage him.
3. 结果状语：常与nly , enugh 或t连用,用于“”；“enugh t...”；“nly t d”句型中。
例：He studied hard nly t fail the exam. He is ld enugh t g t schl. She is s prud as t lk dwn upn thers.
2.原因状语：多用于“sb.+be+adj.+t d”句型中。
例： I’m glad t see yu. She was disappinted t hear the news.
现在分词与不定式作结果状语的区别
例：1. He went hme t find his ld friend Gerge utside the dr.2. The child fell, striking his head against the dr and cutting it.
动词不定式作结果状语强调的是一种意想不到的结果；而现在分词作结果状语强调的是一种顺承的，必然造成的结果。
