人教版高中政治必修1第一课神奇的货币教案
1、外汇与外币的关系：（1）外汇包括外币，但外汇不等于就是外币。外币是指外国的货币，包括外国的纸币、铸币；外汇通常是以外国货币表示的用于国际间结算的支付手段，具体包括外币、外币有价证券、外币支付凭证等。（2）外币属于外汇的范围，但不能把二者等同起来。通常情况下，只有可以自由兑换的外币才是外汇，因为外汇的实质是国际支付手段，如果某种货币不能自由兑换，它就不能成为国际支付手段。外汇执行的 主要是货币的支付手段的职能。（3）持有外汇意味着对外汇发行国拥有债权。持有外汇过多，一方面意味着国际支付能力强和有可能对外汇发行国施加影响；另一方面则意味着大量该由本国享受的资源，被借给外国利用，并要承担外汇贬值的风险。2、关于币值变化的分析：（1）对货币升值的具体分析：一个国家的货币升值（上浮）后，同量的这种货币能比以前换 取更多的他国货币，买到更多的他国商品。
