②其他貨幣與美元掛鉤：即各會(huì)員國(guó)貨幣對(duì)美元的匯率按各自貨幣的含金量與美元確定固定比價(jià)。各國(guó)貨幣與美元的匯率可按各國(guó)貨幣含金量與美元含金量之比來確定，這稱為法定匯率。例如，1946年一英鎊的含金量為3．58134克，一美元的含金量為0．888671克，則英鎊和美元的含金量之比1英鎊＝4．03美元就是法定匯率。這一規(guī)定，使美元等同于黃金，美元從此有了“美金”的說法；與美元比起來，其他國(guó)家的貨幣處于從屬地位，確立了美元在國(guó)際貨幣體系中的中心地位、主導(dǎo)地位正如當(dāng)時(shí)美國(guó)財(cái)政部長(zhǎng)福勒所說：“各個(gè)行星圍繞著太陽轉(zhuǎn)，各國(guó)貨幣圍繞著美元轉(zhuǎn)?！毙〗Y(jié)： “布雷頓森林體系”是一個(gè)以美元為中心的世界貨幣體系，美國(guó)通過布雷頓森林體系，掌握了資本主義世界的經(jīng)濟(jì)命脈。（2）影響：①為世界貨幣關(guān)系提供了統(tǒng)一的標(biāo)準(zhǔn)和基礎(chǔ)，有利于維持戰(zhàn)后世界貨幣體系的正常運(yùn)轉(zhuǎn)，為世界經(jīng)濟(jì)的恢復(fù)和發(fā)展創(chuàng)造了條件。

2、系統(tǒng)的基本特征系統(tǒng)觀念為人們把握復(fù)雜事物提供了一系列科學(xué)方法和原則。第一，整體性原則。第二，有序性原則。第三，優(yōu)化原則。學(xué)生的興趣被激發(fā)，可以再調(diào)起高潮，讓學(xué)生聽一首歌曲，三個(gè)和尚挑水，讓學(xué)生從愉快的歌聲中，明白一個(gè)道理：“三個(gè)和尚沒水喝”，導(dǎo)致這一結(jié)果的根本原因就在于人數(shù)雖然多了，但沒有形成合理的結(jié)構(gòu)，不是相互支持，相互促進(jìn)，而是相互制肘、相互消磨，結(jié)果各要素的力量或作用被內(nèi)耗了，出現(xiàn)了1＋1＜2的效應(yīng)。所以，就要求我們一定要做到：3、掌握系統(tǒng)優(yōu)化的方法的要求（1）著眼于事物的整體性；遵循系統(tǒng)內(nèi)部結(jié)構(gòu)的有序性；注重系統(tǒng)內(nèi)部結(jié)構(gòu)的優(yōu)化趨向。（2）用綜合的思維方式來認(rèn)識(shí)事物鞏固練習(xí)：以鞏固知識(shí)為基礎(chǔ)，培養(yǎng)能力為目標(biāo)。
