1，大家知道，a little 用于修饰比较级的用法比较广泛。如：

2，但是，副词little修饰比较级时，其用法比较有限，主要用于修饰better和more：

1. little better：其意为“好不了多少”，相当于not much better。如：

His second suggestion was little better than his first. 他的第二条建议比第一条好不了多少。

His legs were in little better shape than they had been the year before. 他的双腿与前一年相比没有多少好转。

2. little more (than)：其意为“只”“只不过”。如：

He was little more than a child when his father died. 他父亲去世时，他差不多还是个孩子。

Aid to the Third World is at present little more than a drop in the ocean. 目前对第三世界的援助不过是杯水车薪。

He left school with little more than a basic education. 他只接受了点基础教育就退学了。
