美国政府为什么关门？

在2018年和2019年，美国政府关门事件引起了全球的关注。美国政府关门的原因是什么？下面我们来探讨一下。

Firstly, one of the main reasons for the shutdown of the US government is political differences and disputes. The US government shutdown often occurs when there are differences between the Republicans and the Democrats over certain political issues, such as the budget, immigration, health care and other policies. The two sides cannot reach an agreement on these issues, resulting in a failure to pass the budget and a shutdown of the government.英文翻译：

Secondly, another reason for the shutdown of the US government is the failure of the negotiation process. When the Republicans and the Democrats cannot reach an agreement on the budget or other political issues during the negotiation process, they often threaten to shutdown the government as a means of pressure. Sometimes, this kind of shutdown may be avoided if there is a last-minute agreement or a temporary spending bill is passed.英文翻译：

Thirdly, the shutdown of the US government may also be due to technical reasons. For example, the government may run out of money because Congress has not passed a new budget or because Congress has passed a temporary spending bill that expires before a new budget is passed. Sometimes, this kind of shutdown may be avoided if Congress passes a new spending bill or extends the temporary spending bill.英文翻译：
