Albert Einstein
Albert Einstei ( http: / / www.21cnjy.com )n was born in Ulm,Germany,in 1879.His father owned a factory that made electrical devices.His mother enjoyed music and books.His parents were Jewish but they did not observe many of the religion’s rules.As a child he always loved mathematics,and he had his idea of the theory of relativity when he was only 16 years old.He published his special theory of relativity in 1905.In 1915,he expanded it to a “General Theory of Relativity.” He changed the way we understand the universe.
In 1921,he wo ( http: / / www.21cnjy.com )n the Nobel Prize in Physics.It was given to him,not for his theories of relativity,but for his discovery of the law of the photoelectric effect.This scientific law explained how and why some metals give off electrons after light falls on their surfaces.The discovery led to the development of modern electronics,including radio and television.Albert Einstein taught in Switzerland and Germany.He left Germany when Adolph Hitler came to power in 1933.He moved to the United States to continue his research.He worked at the Institute for Advanced Study in Princeton,New Jersey.Einstein became a citizen of the United States in Nineteen-Forty.Albert Einstein opposed wars.Yet he wrote to President Franklin Roosevelt in 1939 to advise him that the United States should develop an atomic bomb before Germany did.Albert Einstein died in Nineteen-Fifty-Five.He was seventy-six years old.
Archimedes
阿基米德(Archimedes约公元前28 ( http: / / www.21cnjy.com )7～前212)是古希腊著名的数学家和物理学家。静力学和流体静力学的奠基人。公元前287年诞生于地中海西西里岛的叙拉古城（今意大利锡拉库萨）。他的父亲是古希腊天文学家和数学家。阿基米德从小深受父亲的影响,偏爱数学,很早就学习希腊著名数学家欧几里得（约前330~前275）的《几何学原理》。11岁的时候,阿基米德去当时著名的文化中心——尼罗河畔的亚历山大城学习。学习期间对数学、力学和天文学有浓厚的兴趣。在他学习天文学时,发明了用水力推动的星球仪,并用它模拟太阳、行星和月亮的运行及表演日食和月食现象。为解决用尼罗河水灌溉土地的难题,他发明了圆筒状的螺旋扬水器,后人称它为”阿基米德螺旋”。公元前240年,他学成后回到叙拉古,当了国王亥厄洛的顾问,帮助国王解决生产实践、军事技术和日常生活中的各种科学技术问题。公元前212年,叙拉古城失陷,正在聚精会神地研究科学问题的阿基米德,不幸被蛮横的罗马士兵杀害。

Homework today is to find more examples to practice after class.
So much for today. Good-bye, everyone!
被动语态
1.被动语态的构成
英语动词有两种语态:主动语态 ( http: / / www.21cnjy.com )和被动语态。主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。 由于不及物动词不能带宾语,故无被动语态,只有及物动词或相当于及物动词的动词短语才有被动语态,其基本构成方式是”助动词be＋过去分词”。
注意:”be＋过去分词”结构不 ( http: / / www.21cnjy.com )一定都是被动语态,有些动词（如 be,feel,look,seem等）后面的过去分词已转化为形容词,用作表语表示状态。如: The glass is broken.(杯子破了。)
2.主动语态改被动语态的方法
(1) 将主动语态改为被动语态应注意 ( http: / / www.21cnjy.com )三方面:①将主动语态的宾语改为被动语态的主语;②将主动语态的谓语动词改为”be＋过去分词”结构;③将主动语态的主语改为介词by之后的宾语,放在谓语动词之后(可省略)。
(2)含直接宾语和间接宾语的主动语 ( http: / / www.21cnjy.com )态改为被动语态时有两种情况:①把间接宾语改为被动语态的主语,直接宾语仍保留原位;②把直接宾语改为主动语态的主语,此时,间接宾语前要加介词to或for。如:
He gave the boy an ap ( http: / / www.21cnjy.com )ple. →The boy was given an apple.（或An apple was given to the boy.）
Her father bought her a present.
→She was bought a ( http: / / www.21cnjy.com ) present by her father.（或A present was bought for her by her father.）
(3)不带to的动词不定式作宾语补足语的主动语态,改为被动语态时不定式前要加to。如:
They watched the ch ( http: / / www.21cnjy.com )ildren sing that morning. →The children were watched to sing that morning.
(4)带复合宾语的动词改为被动语态时,一般把主动语态的宾语改为主语,宾补在被动语态中作主语补足语。如:
We call him Xiao Wang.→He is called Xiao Wang.
He cut his hair short.→His hair was cut short.
They told him to help me.→He was told to help me.
(5)短语动词是不可分割的整体,改为被动语态时要保持其完整性,介词或副词不可遗漏。如:
We must take goo ( http: / / www.21cnjy.com )d care of the young trees. →The young trees must be taken good care of.
(6)含有宾语从句的主动结构变为被动 ( http: / / www.21cnjy.com )结构时,常用it作为被动结构的先行主语,从句放在句后;也可采用另一种形式。可以这样转换为被动结构的动词有know,say,believe,find,think,report等。如:
People believ ( http: / / www.21cnjy.com )e that he is ill.→It is believed that he is ill.（或:He is believed to be ill.）
3.被动语态改为主动语态的方法
被动语态中介词by后的宾语改为主动语态中的主 ( http: / / www.21cnjy.com )语（或按题意要求确定主语）,按照这个主语的人称和数以及原来的时态把谓语动词形式由被动语态改为主动语态。注意在主动语态中有的动词要求不带to的动词不定式作宾语补足语,此时要把被动语态中的to去掉。被动语态的主语用来作主动语态的宾语。如:
History is made by the people.→The people make history.
4.不能用于被动语态的情况
(1) 某些表”静态”的及物动词(表状 ( http: / / www.21cnjy.com )态而非动作,且常是不可用于进行时态的动词）如have, fit, suit, hold(容纳), cost, suffer, last(持续)等不能用于被动语态。如:
They have a nice car. ( http: / / www.21cnjy.com ) 他们有一辆漂亮的汽车。 My shoes don’t fit me. 我的鞋不合适。
My brain can’t hold so ( http: / / www.21cnjy.com ) much information at one time. 我的脑子一下子记不住这么多资料。
How much／What does ( http: / / www.21cnjy.com )it cost？这值多少钱？ Our holiday lasts 10 days.我们的假期有十天。
This food will last (them)(for) 3 days. 这食物足够（他们）（吃）三天。
(2) 不是所有带介词的动词都能用于被动结构。若是构成成语动词通常有被动态, 否则无被动态。比较:
They arrived at a decision. →A decision was arrived at. 他们作出了决定。
They arrived at the station. 他们到达车站。（不说The station was arrived at.）
He looked into the question.→ The question was looked into.他调查了这个问题。
(3) 动词leave(离开), enter(进入), join(参加)不可用于被动语态。例如:
The car left the road and hit a tree. 车子离开了道路,撞上了树。
(4) 某些及物动词可作 ( http: / / www.21cnjy.com )不及物动词用,特别是后加副词(如well, easily等)时。 主动语态有被动含义, 这类动词常见的有sell, write, wear, wash, cook, open, close, lock, read, record等。如:
His new novel is se ( http: / / www.21cnjy.com )lling well.他的新小说很畅销。 This material won’t wear.这种材料不耐穿。
(5) feel, look ( http: / / www.21cnjy.com ), appear, sound, taste, smell等由实义动词演变而来的系动词,后接形容词作表语,不用被动语态。
Tell me if you feel cold. 你要是感到冷就告诉我。
Those roses smell beautiful. 那些玫瑰好闻极了。
(6) 宾语是不定式或动词的-ing形式时,不可用于被动语态。 Peter hoped to meet her. 彼得希望遇见她。
Mr.Smith enjoyed seeing his daughter. 史密斯先生喜欢看他的女儿。
(7) 宾语是反身代词或相互代词时,不可用于被动语态。如: She can dress herself. 她可以自己穿衣服。
We could hardly see each other in the fog. 在雾中我们彼此几乎看不见。
(8) 宾语是同源宾语时,不可用于被动语态。如 They live a happy life.他们过着幸福的生活。
5. 某些动词的主动形式表被动含义
英语中有很多动词如act ( http: / / www.21cnjy.com ), break, catch, cut, clean, drive, draw, let, lock, open, sell, read, write, wash, wear等, 当它们被用作不及物动词来描述主语特征时,其主动形式常用来表达被动含义。另外,像 owe, beat, cook, bake, print, build, make等,有时可以用主动形式表达被动含义。如:
This kind of radio doesn’t sell well. 这种收音机不太畅销。
The shop opens at eight o’clock. 这个商店八点开门。
The pipe does not draw well. 这烟斗不太通畅。
注意: 主动表被动强调的是主语的特征,而被动语态则强调外界作用造成的影响。例如:
The door won’t lock. 门锁不上。（指门本身有毛病）
The door won’t be locked. 门不会被锁上。（指不会有人来锁门）
His novels sell easily. 他的小说销路好。（指小说本身内容好）
His novels are sold easily. 他的小说容易销售。（主要强调外界对小说的需求量大）
6.某些动名词的主动形式表被动含义
(1) 在need, w ( http: / / www.21cnjy.com )ant, require, deserve和bear等词的后面,动名词用主动形式表示被动含义,其含义相当于动词不定式的被动形式。如: The house needs repairing (to be repaired). 这房子需要修理。
(2) 形容词worth后跟动名词的主动式表被动含义,但不能跟动词不定式; 而worthy后面跟动词不定式的被动形式。
He picture-book is wel ( http: / / www.21cnjy.com )l worth reading.(The picture-book is very worthy to be read.)这画册值得一读。
