在国际商务交流和法律事务中，英文授权书是一种非常重要的文件。它用于确认某人或某个实体被正式授权代表他人行事。无论是商业合作、法律事务还是个人事务，一份清晰且专业的英文授权书都是必不可少的。

以下是一个基本的英文授权书模板，您可以根据具体情况进行调整：

[Your Name]

[Your Address]

[City, State, ZIP Code]

[Email Address]

[Date]

To Whom It May Concern,

I, [Full Name of the Authorizing Party], residing at [Your Address], hereby authorize [Full Name of the Authorized Person] to act on my behalf and represent me in all matters related to [specific matter, e.g., property transactions, business dealings, etc.].

The authorized person is granted full authority to make decisions, sign documents, and perform any actions necessary to fulfill the aforementioned purposes. This authorization is valid from [start date] to [end date], unless otherwise revoked in writing.

All actions taken by the authorized person within the scope of this authorization shall be binding upon me.

In witness whereof, I have executed this letter of authorization as of the date first above written.

请注意，这只是一个基础模板，实际使用时需要根据具体情况填写详细信息，并可能需要律师的帮助以确保其合法性和有效性。此外，在涉及重要事务时，建议咨询专业法律顾问以避免潜在的风险。
