总的来说，利息和利率都是金融领域中重要的概念，但它们在定义和用途上有所不同。利息是借款人需要支付的费用，而利率则是计算这种费用的方式。对于借款人和投资者来说，理解这两个概念的区别是非常重要的，因为这有助于他们做出更明智的金融决策。

英文段落：

Interest and interest rate are two concepts that often appear in the financial field, but there is a clear distinction between them. Simply put, interest is the cost that a borrower needs to pay to a lender, while the interest rate is a way to calculate such cost.

First, let's look at interest. When a person or business borrows money from a bank or other financial institution, they usually need to pay a certain fee as a cost of borrowing, which is interest. The amount of interest depends on the borrowed amount, the duration of the loan, and the interest rate. Interest can be simple or compound, depending on the terms of the loan contract.

Next, we turn to the interest rate. The interest rate is the proportion between the interest that a borrower needs to pay and the borrowed amount. It is usually expressed as a percentage, used to describe the level of cost that a borrower needs to bear. The interest rate can be influenced by various factors, including central bank policies, market supply and demand relationships, and inflation rates.

Overall, both interest and interest rate are important concepts in the financial field, but they differ in definition and usage. Interest is the cost that a borrower needs to pay, while the interest rate is the way to calculate such cost. For borrowers and investors, understanding the distinction between these two concepts is crucial, as it helps them make more informed financial decisions.
