本题答案选A。

1. barely 表示“几乎不”，意思跟hardly 接近，属于否定类副词，故排除该选项。

2. very 和quite 都是程度副词，重在修饰“状态概念”的形容词和副词：

This dictionary is very useful to my English study.

He was driving very carefully then.

I don't have quite many copies left.

You did quite well.

3. badly 也可以用作程度副词，相当于very much，重在修饰动作概念。If you want or need something badly, you want or need it very much.

badly 最经常修饰的动词，是want 和need。此外，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?

你为什么要这么急着走？

Why does he need this money so badly?

他为什么这么急着要这点儿钱?

We have missed you badly since you were gone.

自你走后我们非常想念你。

I wished to get your help badly.

我非常想得到你的帮助。
