Lesson 1 詞匯辨析：
1. I'm not sure whether to go to the one about accidents. 我還沒有決定是否去聽那個有關(guān)事故的報告。
(1) be sure + whether等連詞+不定式
be sure + of/about短語
be sure + that-clause（從句）
這些句型表示主語對所提到的未來或當時的事情有無把握。e．g。
�、� She isn't sure whether to stay in New York next month．下個月是否留在紐約，她還不能肯定。(注：不定式的邏輯主語與全句主語一致)
② I wasn't sure about/of the way，so I asked someone．我對于怎么走沒有把握，所以我就問人了。
�、跧'm sure he'll come．我肯定他會來。
�。�2）be sure to do sth.表示"一定會...，必定會..."。e.g.
It's a really good film-you're sure to like it.它確實是一部好電影，你一定會喜歡
(3)be sure作"有把握"解時，還可用feel sure。e.g.
①I've never felt sure of success．我從來沒有像現(xiàn)在這樣對勝利有充分的信心。
②I feel sure we have disturbed you of your work．我確信我們已打擾了你的工作。
(4)be sure 與be certain
be certain意思是"確信，有把握"，用法與be sure同，即：
be certain + 不定式
be certain + of/about-phrase
be certain + that-clause
但sure強調(diào)主語的心理狀態(tài)，指主語心中無疑或十分確信、有把握，著重于人的內(nèi)心世界，故其主語只能是人，且不能用來形容事件。所以當主語是表示事件的名詞、代詞或it時，只能用certain. certain 著重說明有肯定的理由和證據(jù)使人相信或確信，強調(diào)內(nèi)心世界之外的證據(jù)。e.g.
�、� It is certain to rain．天肯定會下雨。
�、� His information was by no means certain．他的消息-點也不可靠。
�、� It's almost certain that the government will lose the next election．幾乎可以肯定現(xiàn)政府會在下次選舉中輸?shù)簟?/p>
④We are sure/certain of victory．我們確信自己會獲勝。
(5)make sure表示"查明，弄確實"和"(采取行動)確保"，其用法是：
make sure + of-phrase
make sure + that-clause
① I think I locked the door，but I'll just go back and make sure of it/that I did．
我想我是鎖了門，但我還是回去查看一下吧。
②They made sure of winning by scoring two goals in the last five minutes．
他們在最后五分鐘進了兩個球，確保了這場比賽的勝利。
2. Perhaps I'll go to that one。也許我會去聽那個報告。
Maybe it was useful for some people．它(指報告)對一些人或許有益。
這兩句都不表示可能性的句型。此外還有probably和possibly。注意它們的區(qū)別。
�。�1）maybe"大概，或許"，意思與perhaps很接近，多數(shù)地方可以換用，但不及perhaps正式，多用于口語，還可用于禮貌的建議或請求，多用于句首或句末，多用于美國。
(2)perhaps"也許，可能，大概"，可與maybe換用，但比maybe正式。perhaps還可用于建議，清求及溫和的命令，英國用法。
(3)probably"大概，很可能"，所表示的可能性雖不是完全肯定，但比maybe，perhaps實現(xiàn)的可能性大多與動詞連用。
�。�4）possibly"可能地，也許，或許"，較probably意味弱，在肯定句里表可能性很小，在否定、疑問句中與can，could連用，表示"無淪如何也不"，肯定句中與can，could連用，以加強語氣，表示"設(shè)法，竭力地"。e.g.
�、貾erhaps/Maybe I'll go．我或許會去。
�、赥his is perhaps his best novel yet．這也許是他迄今為止寫得最好的一部小說。
�、跴erhaps/Maybe you would like to join us for lunch．也許您愿意和我們一塊去吃午飯。（表請求）

�、轎'll do all I possibly can.我將盡我的所能去做。(與can連用)
�、逫 can't possibly drink any more．我無論如何不能再喝了。
4．I doubt if he'll be asked to speak again next year．我懷疑明年是否會再次邀請他發(fā)言。
用doubt表示懷疑的句型：
(1)doubt + that-clause。e.g.
I doubt that she will get the job．我不相信她會得到那個工作。
(2)doubt + 名詞/代詞。e．g.
I doubt his honesty.我對他的誠實表示懷疑。
(3)doubt + v．-ing form。e.g.

我們曾經(jīng)對能否及時完成這工作懷疑過。
(4)doubt + of-phrase。e．g.
They have never doubted of success．他們從未對取得成功有什么懷疑。
如果要表示"對……沒有懷疑/疑慮"，則用句型
There is no doubt about sth./as to sth./ that-clause。

=There is no doubt as to the troth of the news．消息的真實性無可懷疑。
�、赥here is no doubt that the news is true．

Lesson 2
Background Information:
Ⅰ. Madame Curie
Marie was born in Poland in 1867. She was given the name Marie Sklodowska by her parents. Her father was a teacher. Everyone soon saw that Marie had a quick mind.
Marie's mother died when her youngest daughter was only ten. This made Marie know that she must work hard at her lessons if she wanted to be successful in her life. So she did and won top honors at her school. Marie and her elder sister, Bronya, dreamed of studying in France. But their father did not have enough money to send them there. Then Marie made out a plan: She would teach at home and send her money to Bronya. After her sister finished studying in Paris, she could get work and send Marie the money to study there in return. With tears in their eyes the girls said goodbye to each other, and Marie worked very hard for six years to pay for her sister's studies. At last it was Marie's turn, but by the time she got to France, her sister was married and could not give her much help.
Again Marie worked, she studied in a small room without heat or light. She lived on bread and tea most of the time, but what she cared of most was her science-her study and her research work. This was her world, and she liked her experiment most.
In Paris she met and married Pierre Curie, a young famous scientist. Together they made their experiments in an old house. The Curies were awarded the Nobel Prize for their great contribution to science. In 1911 Madame Curie received another Nobel Prize. It is the only time in history that two Nobel Prizes have been given to the same person, and this person was a woman.
Marie Curie, an extraordinary woman scientist with extraordinary success discovered a hidden power from which the world benefits much. It was this same power, however, that killed her in 1934.
Ⅱ. Marie Curie visited the USA
By the end of World War I, Marie Curie was probably the most famous woman in the world. She had made a decision, however, not to patent radium or its medical applications. As the price of radium escalated(逐漸上升), she found that she did not have sufficient(足夠的) supplies for the radiochemical research that she wanted to undertake at the Institute of Radium in Paris.
Thus, in 1921 Marie Curie made her first visit to the United States with her two daughters. One stop was the Radium Refining Plant in Pittsburgh, where Marie Curie toured the chemical extraction facilities used to prepare radium for the US market. A photo of Marie Curie on the tour is shown.
On May 20, 1921, Marie Curie visited the White House to receive the gift of a gram of radium from President Harding. The dangerous source itself was not brought to the ceremony. Instead she was presented with a golden key to the coffer, in which the radium tubes were placed.
異域風情 The Nobel Prize
A Nobel Prize is considered by most people as one of the highest international honours a person can receive. As you know, the prizes were started by a Swede called Alfred Nobel. Alfred Nobel was born in Stockholm, the capital of Sweden, and lived from 1833 to 1896.
Alfred Nobel was a chemist and inventor. He made two important inventions, and so he became very rich. Although he was rich, Nobel was not a happy man. He never married or had children.Also, he was a sick man a large part of his life. Nobel died at the age of sixty-three. When he died, he left a fund of $900 000. The money was to be used in giving prizes to those who made outstanding achievements in physics, chemistry, medicine, literature and the promotion of world peace.
The first Nobel Prizes were given on December 10th, 1901, five years after Nobel's death. Many famous people from all over the world have been given Nobel Prizes for their achievements. Albert Einstein and Madame Curie were two of them.
Each Prize has three parts. The first part is a gold medal. Second, a winner of a Nobel Prize is given a diploma saying that he has been given the Prize. The third part of the Prize is a large amount of money-about $40 000.
Often a Prize is given to just one person, but not always. Sometimes a Prize is shared. It may be given to two or more people who have worked together. Sometimes a Prize is not given at all if there is no outstanding achievement. In 1972, for example, no Nobel Peace Prize was given. It is the Nobel Foundation in Stockholm that decides whether to give the Prize or not.

語法教學：
復(fù)習定語從句
定語從句分為限定性定語從句和非限定性定語從句。
1) 限定性定語從句：限定性定語從句對所修飾的先行詞起限定作用。 限定性定語從句中關(guān)系詞的使用列表如下：
在句中的作用關(guān)系詞說明
主語 關(guān)系代詞：who/that(指人) which/that(指物 關(guān)系代詞不能省略
賓語 who／whom／that(指人)
which／that(指物) 關(guān)系代詞在非正式
文體中可以省略
定語 whose 名詞前表所有關(guān)系
介詞+關(guān)系代詞 whom(指人) which(指物) 關(guān)系代詞不能用who或that
whose(定語) 名詞前表所有關(guān)系
狀語 關(guān)系副詞：when(時間) where(地點)why(原因) 先行詞為表時間、地點等的名詞 例:
�、貯nna was an American writer who／that interviewed Mao Ze dong in Ya'an．(指人作主語)

�、轍e looked at the box from which the voice came．(介詞+關(guān)系代詞)
他看著那只傳出聲音的方箱子。
2)非限定性定語從句：非限定性．定語從句對所修飾的先行詞(句子)起補充說明的作用，不起限定作用。從句中使用關(guān)系代詞who，whom，which，whose和關(guān)系副詞when，where等，不使用關(guān)系代詞that，作賓語的whom不能用who代替。
例：They visited the city of Hangzhou，which is famous for its beautiful scene．他們參觀了杭州城，它以風景秀麗而聞名。
非限定性從句中關(guān)系詞指代整個句子時，用關(guān)系代詞which。試比較：
�、貰ig floods hit some parts of China in the summer of 1998,which caused a great damage to the country．1998年夏中國部分地區(qū)遭受特大洪災(zāi)，給國家?guī)砹司薮髶p失。(指代整個句子)
�、赥hey got married on July 1，1997，when Hong Kong returned to our motherland．他們于1997年7月1日喜結(jié)良緣，香港在這一天回歸祖國。(指代時間作狀語)
學習中應(yīng)注意的問題(一)
1)先行詞為表示時間或地點的名詞在從句中作主語或賓語時關(guān)系詞的使用。當先行詞為表示時間或地點的名詞時，在從句中作主語或賓語時，應(yīng)使用代詞which或that，不能用副詞when或where．
①a：I'll never forget the days which/that I spent in the country．(which作spent的賓語)
b：I'll never forget the days when I worked in the country．(when代替in the days作狀語)
�、赼：They came to the small village，which was hundreds of miles from the city．(which在從句中作主語)
他們來到這個小村，小村與城市相距幾百英里。
b：They came to the small village，where not more than l00 villagers lived．(where代替in the village作狀語)他們來到這個小村莊，那里的村民不超過一百人。
2)the time，the way等為先行詞時關(guān)系詞的使用。
(1)先行詞為time／moment等表示時間的名詞時，用關(guān)系詞when，that均可，且可省略。
例：By the time (when／that) they arrived，the house had been destroyed completely．等他們到達時，房子已完全燒毀了。
(2)the way用作先行詞，關(guān)系代詞作介詞in的賓語時，通常介詞與關(guān)系代詞可以同時省略；如不使用"in"，則不能用關(guān)系代詞。
例：He hated the ways(which／that)she talked (in)．他不喜歡她說話的方式。
3)關(guān)系代詞只使用that，不使用which的情況。
(1) 關(guān)系代詞前有形容詞的最高級修飾時。
This is the funniest drama that I have seen.這是我看過的最滑稽的劇。
(2)先行詞為不定代詞。如：all，everything，nothing，anything，both．either，much，little，none。
例：①Everything that was taught in class seemed easy for him. 對他來說課堂上教的一切似乎很容易。
(3)先行詞為only，very等詞修飾肘。
例：①It was the only textbook that could be found．這是能夠找到的僅有的一本課本。
�、赥his is the very dictionary that I want to get．這正是我想得到的詞典。
(4)定語從句中固定短語動詞和短語中的介詞不能前置。
例：It was the maths book that the boy was in search of．這是這個男孩正在尋找的數(shù)學書。
5)whose與of which/whom
(1)都可表所有關(guān)系。
(2)of which/whom還可表示"其中的……"(整體的部分)
例：He told us many stories about Long March，of which this is a good example.他給我們講了許多關(guān)于長征的故事，這是其中一個很好的例子。
as和which引導(dǎo)的非限制性定語從句比較:
下面是近年高考題中關(guān)于定語從句的試題
1.The result of the experiment was very good, ____ we hadn't expected． (NMET2000，10)
2.Dorothy was always speaking highly of her role in the play，____, of course，made the others unhappy. (NMET2000，17)
A.when B.which C.this D.what
3.Carol said the work would be done by October,____ personally I doubt very much．(NMET99，19)
A.it B.that C.then D.which
4.The weather turned out to be very good,____ was more than we could expect. (NMET94,39)
A.what B.which C.that D.it
它們的答案分別是C、B、D和B，都是用which引導(dǎo)一個非限制性定語從句，which代替逗號前整個主句的內(nèi)容。
但有時關(guān)系代詞as也可引導(dǎo)非限制性定語從句，as也是代替整個主句的意思。如:
As we all know，he never smokes. The foolish boy made the mistake again，as could be expected. ____ is mentioned above，the number of students in senior high school is increasing．('99上海，4)
A.Which B.As C.That D.It
關(guān)系代詞as和which引導(dǎo)的非限制性定語從句區(qū)別究竟在哪里呢?
1．非限制性定語從句位于句末，而且as或which在從句中作主語、賓語或表語時可互換。如:
He is a farmer as/which is clear from his manners．(在從句中作主語)
This elephant is like a snake，as／which anybody can see．(在從句中作賓語)
2. which引導(dǎo)的非限制性定語從句一般放在句末，而as引導(dǎo)的非限制性定語從句可放在句末，也可放在句中、句首。置于句首時，不能用which替換。如：
Crusoe lost his dog, which made him very sad.
Taiwan is part of China, as/which is known to all.
As we have seen, oceans cover more than 70 percent of the earth.
3.as引導(dǎo)非限制性定語從句時，意為"這一點"、"這件事"，常與see，hope，expect，know，guess等動詞搭配；而which引導(dǎo)非限制性定語從句時，與主句有一種因果關(guān)系，可譯為"所以……"。如：
Cyprus, as you all know, is in the Mediterranean．大家都知道，塞浦路斯在地中海。
Bamboo is hollow，which makes it very light。竹子是空的，所以很輕。
4.as引導(dǎo)非限制性定語從句，并在從句中作主語時，其后面的謂語動詞必須是連系動詞。如果從句謂語動詞是行為動詞，則必須用which。如：
He married her，as was natural.
She refused to take the medicine，which made her mother angry．
It rained hard yesterday，which prevented her from going to Shenyang.
但若從句謂語是usually, happen，be often the case等時，仍用關(guān)系代詞as，不用which。如：He is absent，as is often the case.
幾組正誤辨析：
1．誤：We visited a factory where makes toys for children．
正：We visited a factory which that makes toys for children.
析：此句錯誤的原因是把先行詞a factory當作從句中的狀 語，實際上先行詞a factory在從句中充當動詞makes的主語。故關(guān)系詞應(yīng)使用which或that。
2．誤：After living in Paris for 50years，he returned to the small town that he grew up as a child。
正：After living in Paris for 50years, he returned to the small town where he grew up as a child。
析：此句錯誤的原因是把先行詞the small town當作從句中的賓語，實際上從句中缺少地點狀語。因為從句中謂語動詞grew up是一個不及物動詞短語，其后的as a child已充當了賓語，故從句中缺少狀語，應(yīng)使用關(guān)系副詞where。
3．誤：He paid the boy $15 for washing ten windows，most of them hadn't been cleaned for at least a year．
正：He paid the boy $15 for washing ten windows, most of which hadn't been cleaned for at least a year．
誤：This is the boy with him he worked．
正：This is the boy(that／whom) he worked with。
正：This is the boy with whom he worked．
析：在定語從句中，如果介詞及介詞短語用在從句前，其后必須用關(guān)系代詞which(指物)、whom(指人)。上面兩誤句中先行詞windows(物)，the boy(人)應(yīng)分別使用most of which和with whom。如果介詞及介詞短語用在從句句尾，應(yīng)按普通定語從句對待。

三、詞語辨析
1.accident; incident, event
(1)accident指意外或偶然發(fā)生的事故，特別是不幸的、有損害性的事故。
e.g.He was killed in a traffic accident.ニ在一次交通事故中喪生。
注：accident為可數(shù)名詞，前面可加不定冠詞an，表示“一個，一次”，習慣用語by accident為“偶然”，相當于by chance。
e.g.I met her in the street by accident,yet she had a bad accident three days ago.
我在大街上偶爾碰見過她，然而三天前她卻遭遇了一次嚴重事故。
（2）incident泛指不重要的事件，還可指政治上有影響的重大事件。
e.g.I remember an incident that took place in Mr Li's class.
我記得發(fā)生在李先生課上的一件事。
The Lugouqiao Incident broke out on July 7th，1937. 1937年7月7日爆發(fā)了盧溝橋事變。

如何開發(fā)好中國的西部是一項重大的活動。

e.g.The doctor is treating me for my bad cold.ヒ繳在為我治重感冒。
四、能力訓練
（一）單句改錯
1.I don't doubt if he will pass the final examination.
簡析：if改為that。因doubt“懷疑”，在肯定句中常跟whether或if引導(dǎo)的從句，而在否定句、疑問句中常跟由that引導(dǎo)的從句。
2.Being a Christian,he believes Christianity.
簡析：believes后加in。因believe sb./a statement為“相信某人的話或相信一種說法”，believe in sb.是“信任某人（的行為），或信仰（宗教、真理、原則）”。
3.The doctor has done what he can to cure the patient with a newly-made medicine.
簡析：cure改為treat。因cure強調(diào)“治愈”，treat強調(diào)“治療”，兩者分別常用于句型cure sb.of disease;treat sb.as…,treat sb.with…,treat sb.for sth.。
4.Every word from the teacher will have a great affect on the students.
簡析：affect改為effect。因兩者都為“影響”，但affect為動詞，effect為名詞，常用于have an effect on sb./sth.“對……有影響”。
5.What you asked has something to deal with the matter.
簡析：deal改為do。因have sth./nothing to do with…表示“……與……有/沒有關(guān)系”
6.Several years later,she succeeded finding a job again.
簡析：succeeded后加in。因succeed in sth./doing sth.表示“（干……）成功”。
7.There will be a party in the honour of his success.
簡析：去掉the，因in honour of表示“為了紀念……；為了向……表示敬意”。
（二）翻譯填空
1.我對他所做的事很佩服。
I________him________what he has done.
答案：admire,for
2.他供給子女們衣食。

五、高考真題
1.(上海2000)Although the working mother is very busy,she still____a lot of time to children.
A.devotes B.spends C.offers D.provides
簡析：選A。因這四個動詞的用法為：offer sb. sth./offer sth. to sb.;provide sth.for sb.;spend time(in)doing sth.; devote oneself (time, money, energy)to sth./sb.
2.(上海1999)Washington，a state in the United States, was named________one of the greatest American presidents.

3.（2000上海）Recently I bought an ancient Chinese vase,________was very reasonable.
A.which price B.the price of which C.its price D.the price of whose

4.(NMET2000)The manager discussed the plan that they would like to see____the next year.
A.carry out B.carrying out C.carried out D. to carry out
簡析：選C。因that引導(dǎo)定語從句，從句中用了see sth.done句型，that指代the plan,作賓語。
5.(2001年春)John said he'd been working in the office for an hour,________was true.
A.he B.this C.which D.who
簡析：選C。因which引導(dǎo)非限制性定語從句，其代表前面整個句意。
