t-infinitive as attributive
不定式作定语，一般作后置定语，与被修饰的名词或代词之间是主谓关系、动宾关系、同位关系或修饰关系。
主谓关系(被修饰的名词或代词实际上是不定式的逻辑主语） I need smene t help with the wrk.(Smene will help with the wrk.)
注意：在“某人是第…位做某事的人”固定结构中，不定式与被修饰的词间是主谓关系； Edisn was the first man t invent electric lights.而“某人是第几位被…的人”的结构中，应用过去分词dne做后置定语。He was the first freiner invited t take phts f Chinese pandas.
2. 动宾关系（被修饰的名词或代词是动词不定式的逻辑主语） 　On Sundays, he always has a lt f letters t write. （t write many letters）　　
3 同位关系 (某些抽象名词后面用不定式说明某种情况，陈述某种事实)，如：chance, pprtunity, way, time, right, need, mment, ambitin, desire, prmise, wish, curage, failure等. We students shuld have the curage t face any difficulty. He has n chance t explain it t yu.
4. 修饰关系Nw it is time t begin ur class. 　　
注意： ① 不定式作定语要考虑与主语的关系，主语是不定式的逻辑主语，不定式要用主动式；反之用被动式。 I have many things t d . He wants his bike t be repaired right nw.
there be句型中用主动强调有人去做，被动强调事物本身 There’s a lt f wrk t d. = Smene has t d the wrk. There’s a lt f wrk t be dne. =The wrk has t be dne.
注意事项： 　由于动词不定式与其修饰的词之间往往有动宾关系，而该不定式动词为不及物动词时，其后须加上适当的介词，构成不定式短语，即不定式＋介词结构，介词一般不可省去，如： I need a pen t write with Give me sme paper t write n. There are sme thing t be grateful fr. She has a child t take care f. There is nthing t wrry abut. He has n friend t depend n. I've gt a lt f things t see t this mrning. 今天上午我有许多事情要处理。
t-infinitive as adverbial f result
1. 多用于固定句型搭配中，也可以表示出乎意料，意想不到的结果，常常限于learn, find, be tld, see, hear等动词。 He gt t the statin nly t find the train had gne. 2. 不定式表示结果常见于下列句型　 1)  t d （如此…而能够…）Wuld yu be s kind as t lend me yur bicycle? 把你的自行车借给我好吗？2)  t d （如此…而能够…）We are nt such fls as t believe him.我们还没蠢到会相信他的地步3) enugh t d （足够地…而能够… ）He didn't run fast enugh t catch the train. 他跑得不够快，没赶上火车。　
5)  d （太…而不能够…） His eyesight is t pr t read such small letters. 他的视力太差了，看不清这么小的字。 注意：t之前如果有nly, nt, never, all, but,此时不定式不再表否定意义，而表肯定意义，nly t 表“非常”、“很”意。如：They are nly t lucky t g abrad fr a visit. 他们很幸运去国外访问。 2. One is never t ld t learn. 活到老学到老。 另外，t后如果是happy, glad，kind, anxius, easy, delighted, eager, pleased, ready, surprised, willing之类形容词时，不定式也表肯定意义，如：She was t happy t meet her ld friend in the street.
