The act of a government or group using power to stop people from speaking, sharing news, or protesting.
用法模式：
the suppression of [information/opposition/protests]
常见错误：
Learners often confuse "suppression" with "oppression."

Also, do not say *"suppression protests"*; use the pattern *"suppression of protests"*.
