1, Small and little are both adjectives. We use small to talk about the size of something. —–都可以尺寸小。
- Your cat is very small.
- Can I have two small pizzas please?
2, We can use little to refer to size in the same way as small, but we usually use it with another adjective to express an emotion. —–Small用来形容某人、某物尺寸小，几乎不带感情色彩；Little是个“感情丰富”的词，多用在口语中，带有喜欢、讨厌、怜惜等感情。
- He’s a clever little boy.
- Nobody’s looking after that poor little dog.
