1. What is an Exchange Rate? | 什么是汇率？

The exchange rate is the price of one currency expressed in terms of another currency. For instance, if the exchange rate for the British pound (GBP) against the US dollar (USD) is 1.30, it means that £1 can be exchanged for $1.30.

汇率是用一种货币表示的另一种货币的价格。例如，如果英镑对美元的汇率是 1.30，这意味着 1 英镑可以兑换 1.30 美元。

Exchange rates can be quoted in two ways: direct (foreign currency per unit of domestic currency) or indirect (domestic currency per unit of foreign currency). In the UK, it is common to express how many dollars one pound buys – this is a direct quotation for the UK.

汇率可以有两种报价方式：直接标价（每单位本币兑换的外币数量）或间接标价（每单位外币兑换的本币数量）。在英国，通常表示一英镑能买多少美元——这属于英国的直接标价法。

Economists also refer to the trade-weighted exchange rate, which is an index measuring the value of a currency against a basket of currencies of the country’s main trading partners, weighted by trade shares.

经济学家还提到贸易加权汇率，它是一个指数，衡量一国货币相对于其主要贸易伙伴一篮子货币的价值，并根据贸易份额加权。
