interesting应该用a还是an

interesting应该用a还是an interesting应该用a还是an,为什么呢? There is a interesting book.还是an interesting book? interesting,的定冠词是a还是an It's so interesting a book 为什么我觉得应该用such an it is an interesting book 变感叹句是how interesting an book 还是 how interesting a book? -interesting an story it is!感叹词应该用什么? 是He is a very interesting boy 还是He is an very interesting boy?我是说,是不是interesting前面加个very,那个a就是用来修饰very的,而不是用an? I have never seen _____book before.应该填a more interesting 还是the most interesting? I am an person 用 interested 还是 interesting如题 ( ) __________ interesting story I have ever heard!A) What B) How C) What a D) What an请问是C还是D?到底是因为有interesting而用an 还是主语是story而用a? interview前面冠词应该用a还是an use 和 m 前,应该用 a 还是 an . house的前面应该用a还是an? an interesting places=a places of interest有a或an为什么place还加s?还是是“an interesting place=aplace of interest”? 这种句型应该用a还是an?a/an+形容词+apple 用a/an填空 ( )popular ( )important ( )unimportant ( )interesting ( )uninteresting 可不可以用an interesting man
