I was having a nap when suddenly the telephone rang的意思?

I was having a nap when suddenly the telephone rang的意思? I felt better after having a nap.此处为何要用having 而不是过去式? on the way I was able to take a nap on the way over.这句话中on the way I was having a hard time _____ (find) your school. I was having a hard time doing的意思 take a nap 音标 A nap是什么意思 -------,someone rang me upa having a bath b when i was having a bath I was having a hard time finding the school.这个句子为什么用having I was seven o'clock in the evening,The Smiths ------supper.A was having,B were having I was excited about the idea of having aI was excited about the idea of having a dog.怎么翻译 I was having dinner at a restaurant .having dinner 前为什么 有was ,having dinner 不也是一个动词短语,能当谓语吗 I don't like being b by anyone while I am taking a nap I make a habit of taking a nap after lunch怎么翻译 I have a nap after lunch的否定句怎么写 oh you're so slow..I'll go take a nap,中文意思是什么 I want to take a nap so do not disturb for the next half hour. TO以及BE been的用法I must to be take a nap.i must be take a nap.i must to take a nap.i must take a nap .请问这4句中 哪一句是对的?我总是搞不明白到底什么时候要加BE,什么时候不加be,还有什么时候要加TO,什么时
