谢谢曹老师的讲解!

所以曹老师 以上结构的不定式都有2种解释 又可以做定语又可以做状语？虽然觉得曹老师分析的很好 但是内心还是有点小纠结 毕竟不太喜欢共存态 哈哈

Huddleston的《剑桥英语语法》在讲解悬空不定式一节时指出，不定式分句作目的状语时，可以为悬空不定式，也可以是普通不定式。当不定式的逻辑宾语为句子的宾语，而且不定式有目的意义时，就存在二种不同的解释了：1 不定式作定语，表示动宾关系；2 悬空不定式作与宾语有关的目的状语。

It's nice having the expectation to perform well. NPR: Flanagan Best US Hope In Boston Marathon In Years 曹老师： 1）这里为什么不是...nice to have...呢？ 2）另外，不定式 to perform 是及物动词，宾语是前面的expectation吗？

1 动名词也可以作主语，为什么一定要用不定式呢。你应该通过阅读了解多种表达方式。2 perform在此是不及物动词，这不是很明显的吗。这不是反射不定式。

老师，It's nice having the expectation to perform well. 1）是不是等同于 It's nice to perform well having the expectation = It's nice to perform well with the expectation ？ 2）原句 It's nice having the expectation to perform well. 应该是 动状结构？ 谢谢老师

It's nice having the expectation to perform well.= It‘s nice that you expect/want to perform well. ’

谢谢老师。 顺便请教您： It's nice having the expectation to perform well. It's nice to have the expectation to perform well. 上面2句含义有差别还是相同呢？谢谢。 我感觉不定式应该是还没有发生。 动名词表示了一种通常的情况。 不知对否？

意思基本相同，不必作区分。

It's nice having the expectation to perform well.= It‘s nice that you expect/want to perform well.这个等式里，曹老师省略了两步，可以有点儿难理解，我试着补充一下。 第一：It's nice having the expectation to perform well=it's nice that i have the expectation to perform well. 这是把不定式转换为从句。 第二：it's nice that i have the expectation to perform well.=it's nice that i expect to perform well. 当抽象名词由相应动词转化而来，而相应动词接不定式作宾语时，其转化的名词多接不定式作定语。这是把它再转回去 两步之后才是结果：It's nice having the expectation to perform well.=it's nice that i expect to perform well.
