Cách sử dụng
The expression "as/that was" is used to refer back to something that was previously mentioned in a conversation or text. It is often used to emphasize a point or to clarify what was said before. For example, if someone says "It was a really hot day," another person might respond by saying "As/That was the day we went to the beach and got sunburned." This indicates that the hot day being referred to is the same one that they had previously mentioned. The expression can also be used to connect two related ideas, such as "He's always been good at math, as/that was his favorite subject in school."
