Unit 16 The United States of America教案
Ⅰ.Brief Statements Based on the Unit
The United States of America is a developed country and also a booming country,which has a history of only 200~300 years.After the USA was founded,the American Civil War broke out in 1861,which brought suffering to the people of the USA,especially those in the South.Rebuilding the South became an essential task at that time.This unit mainly talks about the rebuilding and development of the American South.And Atlanta is a good illustration.It also deals with the bison on the plains of America.Because the bison was killed in huge numbers by European settlers,the balance of the whole wildlife was destroyed.After learning the unit,we let the students learn about the early history of America.Besides,some useful expressions and phrases should be mastered,and Non-finite verbs need to be reviewed,especially their passive forms.
Ⅱ.Teaching Goals
1.Talk about the USA.
2.Practise describing places.
3.Review Non-finite Verbs(2).
4.Write a comparison essay.
Ⅲ.Background Information
1.The American Civil War
The war of 1861~1865 between the northern states (the Union) and the southern states (the Confederacy) is also called the War between the States or the War of the Rebellion.There were many causes,of which the most important were disagreement over slavery,and the quarrel concerning Federal control and States’ Rights.The direct cause of the war was the election of Lincoln as President;this was followed by the secession of the southern states from the Union and the founding of the Confederacy,with Jefferson Davis as its President.The North had many advantages,a far greater population,more railway lines,and more factories.But the Confederates fought hard and were at first successful:they won the battles of Bull Run and Fredericksburg;but then Lee was defeated at Gettysburg and the Union army led by Grant won control of Mississippi.Admiral Farragant forced New Orleans to surrender:Texas,Arkansas and Louisiana were cut off from the rest of the Confederacy.After the Union won the Vicksburg campaign,Sherman made his march through Georgia to the sea,and Lee surrendered to Grant at Appomatton Court House,Virginia,on April 9,1865.Lincoln was assassinated in the same month.Slavery was declared unconstitutional.The period after the war (Reconstruction),when the South was occupied by the Worth,left bitterness that has not yet entirely vanished.During Reconstruction the southern states were admitted back into the Union.
2.The War of American Independence
(Also called the Revolutionary War 1775~1783)
The struggle of the thirteen British colonies in North America for independence ended in the forming of the USA.The main causes of the war were taxes imposed by the British government,e.g.the Stamp Tax of 1765 and the Tea Tax.The colonies rebelled in 1775;the first shots were fired at Lexington,and the First battle was fought at Bunker Hill.The continental Congress appointed General Washington as leader of its forces,and issued the Declaration of Independence on July 4,1776.General Burgoyne led a British army down from Canada but was forced to surrender at Saratoga (Oct.1777).He was supposed to meet the army of General Howe,who managed to occupy Philadelphia.Washington spent the hard winter of 1777~1778 at Valley Forge,and had difficulty in keeping his men together,France (1778),Spain (1779)and the Netherlands (1780)joined the war against Britain.British forces under Cornwallis won victories in the South where Britain had some popular support,but Cornwallis was defeated at Yorktown,Virginia,and forced to surrender (Oct.19/1781),which practically brought the war to an end.At sea,Britain had to fight to keep her naval supremacy,but after Yorktown the American ports were lost one by one.The war was ended by the Treaty of Paris,1783,which recognized the independence of the USA.
3.Slavery in the United States
The African ancestors (祖先) of today’s black Americans were brought to the US as slaves in the seventeenth,eighteenth,and nineteenth centuries.They worked on farms,especially the large farms in the southern states.Slowly they became a necessary part of the economic (经济) system (体制) of the South.
Slaves did not have the right of people;according to the law,they were a “thing” which belonged to the person who bought them.They had to obey the orders of their owners without questions.They were not allowed to learn to read;their owners feared the educated slaves would begin to think about the injustice of the system and would learn to struggle for their freedom.Slaves had to work long hours in very unhealthy conditions.Their owners had complete power over them.They could be bought and sold like animals.At the slave markets,black children were separated from their parents and never allowed to see them again.Slave owners had the right to punish the slaves who broke the law or was against the system.Slaves were often beaten or even killed by their owners.After the Civil War,one free slave reported that his owner killed an older slave who was teaching him to read.In theory an owner who treated a slave badly could be punished.In practice,however,the law meant nothing.
Opposition to slavery began very early in the history of the US—in 1671—but little progress was made until the beginning of the nineteenth century.By 1804 slavery was illegal (非法的) in the northern states.But it continued,and even grew,in the southern states,which depended on cotton for their economic wealth.Slavery,ended in the South only after the Civil War.For blacks,however,the end of slavery was only a beginning,the late beginning of a long and difficult struggle for true justice.

Ⅰ.异域风情
Weddings in the U.S.
Weddings in the United States vary as much as the people do.There are church weddings with a great deal of fanfare1;there are weddings on mountain-tops with guests barefooted2;and there have been weddings on the ocean floor with oxygen tanks for the guests.But many weddings,no matter where or how they are performed,include certain traditional customs.
Before a couple is married,they become engaged.And then invitations are sent to those who live nearby,their close friends and their relatives who live far away.When everything is ready,then comes the most exciting moment.
The wedding itself usually lasts between 20 and 40 minutes.The wedding party enters the church while the wedding march is played.The bride carrying a bouquet enters last with her father who will “give her away”.The groom enters the church from a side door.When the wedding party is gathered by the altar3,the bride and groom exchange vows.It is traditional to use the words “To have and to hold from this day forward,for better,for worse,for richer,for poorer,in sickness and in health,to love and to cherish,till death do us part”.Following the vows,the couple exchange rings.Wearing the wedding ring on the fourth finger of the left hand is an old custom.After the ceremony4 there is often a party,called a “reception” which gives the wedding guests a chance to congratulate the newlyweds.
The car in which the couple leaves the church is decorated5 with balloons,streamers and shaving cream.The words “Just Married” are painted on the trunk or back window.The bride and groom run to the car under a shower of rice thrown by the wedding guests.When the couple drives away from the church,friends often chase them in cars,honking6 and drawing attention to them.And then the couple go on their honeymoon.

Ⅱ.知识归纳
1.浅析非谓语动词的被动式结构
非谓语动词的逻辑主语是该非谓语动词动作的承受者时，一般要用非谓语动词的被动式。如何在句中使用这些被动式呢？现分述如下：

经常有人提醒我们自身的缺点是有必要的。
②用作某些动词的宾语。如：
He asked to be sent to work in Tibet.
他请求派他到西藏去工作。
He hated to be flattered.

孩子们将去医院打预防针。
She was not old enough to be given such heavy work.

有时可用不定式的完成被动式，表示当时已经完成的被动动作。这样的被动式可在句中充当上面所述的各种语法成分。如：
It was a good thing for him to have been criticized.
他受到批评是件好事。（to have been criticized作真正的主语）
（2）动名词的被动式
①用作句子的主语。如：
His being neglected by the host added to his uneasiness.

be aimed at是aim at的被动语态。aim for强调最终目的。总之，at强调“目标”，for强调最终目的。如：

Ⅳ.能力训练
1.单句改错
(1)How have you done with the letter?
答案：应将done改为dealt或将How改为What。因为习惯上how常与deal with连用，what常与do with连用。
(2)These girls called out their names in turns.
答案：应将turns改为turn。因为in turn是一个固定介词短语，意思是“依次、逐个地”。
（3）These agreements have an affect on both the buyer and the seller.
答案：应将affect改为effect。因为affect是动词，effect是名词，在这里，have an effect on意思是“对……有影响，起作用”。
（4）My remarks were not aim at you.
答案：应将aim改为aimed。因为be aimed at是一个短语，它的意思是“针对，目的是”。
（5）I’d like the question not to raised again.
答案：应在to后加be。因为问题是被提出，它们之间是被动关系，所以要用被动语态。
（6）The flight was delayed as the result of fog.
答案：应将the改为a。因为as a result of是一个固定短语，它的意思是“由于……的
原因”。
（7）She seems to finish her work.
答案：应将finish改为have finished。因为不定式动作是发生在谓语动词所表示的动作之前的，所以应该用不定式的完成式，即to have done。
2.根据所给汉语完成下列各句

答案：died out
(2)那天我们打死打伤了大量的敌人。

A.To wait B.Have waited
C.Having waited D.To have waited
简析：选C。本题考查非谓语动词的用法。作时间状语应该用现在分词；又因“wait”发生在“realize”之前，应用完成式。
7.(2004北京春)
He was in hospital for six months.He felt as if he was______from the outside world.
A.cut out B.cut off C.cut up D.cut through
简析：选B。cut out“切掉，裁剪出”；cut off“断绝，使隔绝”；cut up“切碎”；cut through“抄近路，凿穿”。该句意为：他在医院呆了六个月，觉得好像与外界隔绝了似的。可见B为最佳答案。
