在查看外网新闻时，我们可以看到官方的说法是Canada eases Covid-19 travel rules. 这里ease 是缓解的意思。
英文释义是: to make or become less severe, difficult, unpleasant, painful, etc.
比如我们会常用到的减轻痛苦就可以说ease the pain
举个例子：
▲ These pills should ease the pain.
▲ 这些药丸能缓解疼痛。
当然除了ease,还可以用remove:
Government of Canada will remove pre-entry test requirement for fully vaccinated travellers on April 1
这句新闻的标题中就是用的remove, to take something or someone away from somewhere, or off something
