戰(zhàn)國陰陽五行家鄒衍認(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,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: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)。孔子所受天命,不是一種“法統(tǒng)”,而是一種“道統(tǒng)”。董仲舒說:“《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)。邪辟之說滅息,然后統(tǒng)紀(jì)可一而法度可明,民知所從矣?!?/p>

⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand,70% think space is worth exploring because we have benefited a lot from it,such as using satellites for communication and weather forecast. What’s more,with further space research,we may solve the population problem by moving to other planets one day. Also,space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

學(xué)生探究案例:找出不同等級(jí)城市的數(shù)目與城鎮(zhèn)級(jí)別的關(guān)系、城鎮(zhèn)的分布與城鎮(zhèn)級(jí)別的關(guān)系并試著解釋原因。在此基礎(chǔ)上,指導(dǎo)學(xué)生一步步閱讀書上的閱讀材料,首先說明這是德國著名的經(jīng)濟(jì)地理學(xué)家克里斯泰勒對(duì)德國南部城市等級(jí)體系研究得出的中心地理論,他是在假設(shè)土壤肥力相等、資源分布均勻、沒有邊界的平原上,交通條件一致、消費(fèi)者收入及需求一致、人們就近購買貨物和服務(wù)的情況下得出的理想模式。然后指導(dǎo)學(xué)生閱讀圖2.14下文字說明,理解城市六邊形服務(wù)范圍形成過程。指導(dǎo)學(xué)生讀圖2.15,找出圖中城市的等級(jí)、每一等級(jí)六邊形服務(wù)范圍并敘述不同等級(jí)城市之間服務(wù)范圍及其相互關(guān)系,從而得出不同等級(jí)城市的空間分布規(guī)律,六邊形服務(wù)范圍,層層嵌套的理論模式。給出荷蘭圩田空白圖,讓學(xué)生應(yīng)用上面的理論規(guī)劃設(shè)計(jì)居民點(diǎn)并說出理由,再和教材上的規(guī)劃進(jìn)行對(duì)照。然后給出長三角地區(qū)城市分布圖和各城市人口數(shù),讓學(xué)生對(duì)這些城市進(jìn)行分級(jí),概括每一級(jí)城市的服務(wù)功能、統(tǒng)計(jì)每一等級(jí)城市的數(shù)目以及彼此間的平均距離,總結(jié)城市等級(jí)與服務(wù)范圍、空間分布的關(guān)系?
