All of his friends each have an iPad, and he ______ wants one, too.
A.badly B.very C.quite D.barely
本题答案选A。
1. barely 表示“几乎不”，意思跟hardly 接近，是否定类副词，故排除该选项。
2. very 和quite 都是程度副词，重在修饰“状况定义”的形容词和副词：
This dictionary is very useful to my English study.
He was driving verycarefully then.
I dont have quite many copies left.
You did quite well.
3. badly 也可以用作程度副词，等于very much，重在修饰动作定义。If you want or need something badly, you want or need it very much.
badly 最常常修饰的动词，是want 和need。除此之外，一些表达人的“欲想，好恶”之类的动词，也可被badly 修饰。
Why do you want to go so badly?
你为何要这么急着走？
Why does he need this money so badly?
他为何这么急着要这点儿钱?
