Recognize these for context; they are not the main practice focus.
Learning Note
`卖给` and `拿给` can take two pieces of information: the person first, then the thing. In `还要吗`, `还` means still or more.
Pattern: `动词 + 给 + 人 + 物`
After `卖给`, `拿给`, or `送给`, you can say the person first, then the thing.
Pattern: `A + 比 + B + 形容词 + 数量 / 一点儿`
To say how much the difference is, put the exact amount after the adjective. For a small difference, use `一点儿`.
