2
flexible or easily adjustable
Able to change easily when the situation is different, especially about rules, plans, or ideas.
用法模式：
elastic [rule/plan/deadline]
常见错误：
Learners may overuse "elastic" for people, saying things like "He is very elastic" to mean he is open-minded. In this sense, it is more natural to say a person is "flexible" or "open"; use "elastic" mainly for rules, plans, ideas, or concepts.
近义词
flexible (Most common everyday synonym for being willing or able to change.)
|
adaptable (Focuses more on people and systems changing themselves rather than on rules being loose.)
反义词
strict (Rules or people that do not allow change or exceptions.)
|
rigid (Very unchanging and inflexible, often with a negative tone.)

stretchy band or material
A thin, stretchy band or piece in clothes that makes them tight and helps them stay in place.
用法模式：

Learners sometimes confuse the noun "elastic" with "rubber band." A "rubber band" is a loop of rubber used mainly for holding small objects together; "elastic" (noun) is more general and is often sewn into clothes.
近义词
elastic band (More specific; clearly refers to a band rather than elastic material in general.)
|
stretch band (Less common; used in some contexts for similar stretchy bands.)
