Question

This is useful book.He wants to buy it at one. A,a quite B,quite a C,an quite D,quite an

选哪个？为什么

Answer 1

This is （quite a ）useful book. He wants to buy it at once 最后一单词是once。
选B。 quite 做副词， 修饰带不定冠词的形容词时的搭配一定是： quite a + 形容词
同时， quite a 词义上也表达的是， 相当的。
例如， She had quite a long show.

Answer 2

正确：B
quite a/an +adj.=a very +adj.+n.
useful以辅音因素开头，故选择a.

Answer 3

cd排除我觉得选b

Answer 4

选D，quite 后是a或者an或者the。useful 前只能放an
