Sorry, it is urgent because I am going to have an exam soon. This exam very important so I cannot fail. Within a few days before exam, I am still cannot understand about the usage between gerund and infinitive. Upon the search result on internet, gerund and infinitive both can use as subject, object and complement.
Examples:
1. Reading helps you learn English. subject of sentence
2. Her favorite hobby is reading. complement of sentence
3. I enjoy reading. object of sentence
Examples:
1.To learn is important. subject of sentence
2.The most important thing is to learn. complement of sentence
3.He wants to learn. object of sentence
Q: 1) She delayed____ (get) out of bed. (answer: getting).
3) I offered______ (help) (answer: to help)
However, there is no explanation about how to differentiate the question that which to use gerund or infinitive?
