A government shutdown is a situation in which a government ceases all or part of its functions.
政府关门是指政府停止行使其全部或部分功能。

The US federal government begins a partial shutdown, the first in 17 years, after the two houses of Congress fail to agree a new budget.
美国国会参众两院未能就一项新的预算达成一致意见，导致联邦政府部分部门关门，这是17年来的头一回。
