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(lái)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(shuō)法；與美元比起來(lái)，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(shuō)：“各個(gè)行星圍繞著太陽(yáng)轉(zhuǎn)，各國(guó)貨幣圍繞著美元轉(zhuǎn)。”小結(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。

戰(zhàn)國(guó)陰陽(yáng)五行家鄒衍認(rèn)為，歷史中的朝代更替是由于五德運(yùn)行產(chǎn)生的影響。按照鄒衍的學(xué)說(shuō)，每個(gè)朝代必須與五德之一相連，因此，這個(gè)朝代就應(yīng)當(dāng)遵循這五德之一的要求來(lái)運(yùn)轉(zhuǎn)。董仲舒修改了這個(gè)理論，認(rèn)為朝代的更替不是依循五德運(yùn)行的順序，而是依循“三統(tǒng)”，即黑統(tǒng)、白統(tǒng)、赤統(tǒng)的順序。他在《三代改制質(zhì)文》中說(shuō)：每個(gè)朝代都依循一統(tǒng)，每統(tǒng)又各有其為政的系統(tǒng)。按董仲舒的說(shuō)法，夏朝代表黑統(tǒng)，商朝代表白統(tǒng)；周朝則是赤統(tǒng)。夏、商、周三朝完成了這一歷史循環(huán)。之后，歷史又開始一次新的循環(huán)，新的朝代又應(yīng)當(dāng)代表黑統(tǒng)。繼承周朝統(tǒng)治的既不是秦朝，也不是漢朝，而是孔子，他承受天命，創(chuàng)立了黑統(tǒng)?？鬃铀芴烀?，不是一種“法統(tǒng)”，而是一種“道統(tǒng)”。董仲舒說(shuō)：“《春秋》大一統(tǒng)者，天地之常經(jīng)，古今之通誼也。今師異道，人異論，百家殊方，指意不同，是以上亡以持一統(tǒng)；法制數(shù)變，下不知所守。臣愚以為諸不在六藝之科孔子之術(shù)者，皆絕其道，勿使并進(jìn)。邪辟之說(shuō)滅息，然后統(tǒng)紀(jì)可一而法度可明，民知所從矣?！?/p>

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角）left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything. For this reason, I think there are better stories that can be used to impress upon people with the need for personal responsibility.Step 8 Pair workExchange drafts with a partner.
