Analysis:
The original sentence "the company's opening advertisement said: free small gifts, while stocks last." In Chinese, the words "free" and "gift" are repetitive, and one of them needs to be removed. Because "free" means giving, and "gift" means free, so you can choose one of them, so change this sentence to: A company's opening advertisement says: Give small gifts until they are given.

Correction: it is often used to modify ill-defined sentences such as improper collocation, improper words and unclear reference.
For example, "his grades have improved significantly."
Change: "His grades have improved obviously."
