1 This woman is one of the greatest scientists of all times. Even her name tells you that she likes science: a good scientist should want to find out manswers and ask many questions. In other words they should be curious. This woman was certainly curious. Together with her husband, she tried to learn the secrets of radioactivity. The couple were awarded the Nobel Prize for Physics in 1903. Eight years later,she received a second Nobel Prize, this time forchemistry.
2 It is said that this English gentleman was sitting in his garden one day when suddenly he was hit by a falling apple. The story is probably not true, but this man did mention that he got one of his best known ideas while watching apples fall from a tree. His name makes you think that he was not too interested in old things. He discovered the force of gravity, and he drew up a system of how objects move. His laws for motion are still used in physics today, at least in schools and universities.
3 Food is what sets this great mind on fire. Rice, to be exact. This great mind has spent most of his life looking for ways to help farmers grow more rice so that all of us will have enough food to eat. He is known as the father of modem rice, but because of his long friendship with all the farmers in China, he would rather be known as “the farmer”.
Answers to the exorcises:
Great Mind No 1: Madame Curie
1 This great mind was on fire for radioactivity.
2 The scientist's name is similar to the English word
curious, meaning being interested in something.
(Curie sounds like the beginning of curious.)
Great Mind No 2: Sir Isaac Newton
1 This great mind was on fire for gravity.
2 The scientist's name is similar to the English word
for something not old. (New-Newton)
Great Mind No 3: Yuan Longping
1 He is known for his work with rice / in agriculture.
2 He wants to be called the farmer.
3 Various answers are possible. They are all passionate
about what they do. / They are on fire for something.
They have all made important contributions to
science and society.
Great Mind No 4: Various answers are possible.

Part 1
Scientists often look at nature in order to find new ideas.In ancient times, Chinese scientists studied how spiders make silk. Modern scientists are interested in the spider,too. A spider can make silk that is much stronger than most man-made materials. A spider's silk doesn't break easily. Instead of breaking, it gets longer. Best of all, the spider produces the silk without the use of dangerous or poisonous chemicals. If we could learn to use the technique, we might be able to use the strong silk to make things like seat belts and wires that hold up bridges.
Part 2
There are many other examples of how new technology has been developed by learning from nature. A group of German scientists wanted to find out why leaves and flowers are able to stay so clean. They decided to take a closer look at the white lotus, a flower that is known for its clean leaves. At first, the scientists believed that a very flat leaf would be better at staying clean. However,when they looked closely at the white lotus, the scientists saw that the leaf was in fact covered with tiny hairs and needles. The needles and hairs collect the dust that falls on the leaf so that a raindrop can easily wash it off. The German scientists used this technique to design a new kind of paint. The new paint could keep houses looking clean for years.
Scientists also believe that the butterfly could teach us a way to keep our computers cool. A computer must be kept cool to function well. The fans we use today are not always good enough. The butterfly is cold-blooded and must change its body temperature all the time. Scientists have found that there are small parts on its wings that the butterfly uses to change its temperature. If scientists can learn how this is done, it may be possible to use the samemethod to keep computers from becoming too hot.
Answers to the exercises:

1 A spiders can make silk that is much stronger than
most man-made materials.
2 A spider's silk doesn't break easily.
3 Best of all, the spider makes the silk without the use
of dangerous or poisonous chemicals.

Background information
閱讀下面材料，回答下列問
( A )
A black hole itself is invisible because no light can escape from it. In fact, when black holes were first hypothesized( 假設(shè) ) they were called "invisible stars. " If black holes are in-visible, how do we know they exist? This is exactly why it is so difficult to find a black hole in space! However, a black hole can be found indirectly by observing its effect on the stars and gas close to it. For example, consider a double-star system in which the stars are very close. If one of the stars explodes as a supernova( 超新星 ) and creates a black hole, gas and dust from the companion star might be pulled toward the black hole if the companion wanders too close. In that case, the gas and dust are pulled toward the black hole and begin to orbit around the event horizon and then orbit the black hole.
The gas becomes heavily compressed( 壓縮的 ) and the friction
( 摩擦 ) that develops among the atoms changes the kinetic( 運動的 ) energy of the gas and dust into heat, and x-rays aregiven off. Using the radiation( 射線 ) coming from the orbiting material, scientists can measure its heat and speed. From the motion and heat of the spreading matter, we can infer" the presence of a black hole. The hot matter circling near the event horizon of a black hole is called an accretion disk.
John Wheeler, a well-known theorist, compared observing these double-star systems to watching women in white dresses dancing with men in black tuxedos within a dimly lit ball- room. You see only the women, but you could predict the existence
of their invisible partners because of the women 's spinning and whirling( 旋轉(zhuǎn) ) motions around a central axis( 軸 ). Searching for stars whose motions are influenced by invisible partners is one way in which astronomers search for possible black holes.
The selection mainly tells us ___________.
Key: what a black hole looks like
Animal or plant What it can do How we could use it
Spider It can make strong silk without using dangerous or
Poisonous chemicals. We could use it to make better seat belts and stronger
wires to hold up bridges.
White Lotus
It keeps its leaves clean using tiny hairs and needles. We could use the same technology to make paint
that would stay clean.
Butterfly The butterfly uses small parts on its
wings to change its temperature. We could use the same method to keep computers
cool.
( B )
Stephen Hawking in China
Stephen Hawking, the disabled author of A Brief History of Time is launching his second journey to China in Hang-Zhou of Zhejiang Province. His first visit was over 10 years ago.
The great theoretical scientist has been invited to attend a state-of-the-art mathematics research institute at Zhejiang University, Hangzhou-based Dushi Kuaibao reported.On Sunday evening, he made his debut at a press conference held at Shangri-La hotel, Hangzhou. Hawking appeared at about 5:00 p.m. with his wife.
The 50-year-old man answered a total of nine questions with the help of his computer."Experts in theoretical science are dispersed around the world but we need communication. I am very glad that the world's first-class conference is being held in China this time, "he said.
I find the real universe much more interesting than the one in the film Star Wars," Hawking joked. "I encourage young people to study theoretical physics first if they are interestedin it. Stephen Hawking has worked on the basic laws which govern the universe. With Roger Penrose he showed that Einstein's General Theory of Relativity implied( 隱含 ) space and time would have a beginning in the Big Bang and an end in black holes. These results indicated it was necessary to unify General Relativity with Quantum Theory, the other great scientific development of the first half of the 20th century.
One consequence ( 結(jié)果 ) of such a unification theorywould be that black holes would not be completely black, but emit( 防射 ) radiation and eventually evaporate( 蒸發(fā) ) and disappear. Another conjecture is that the universe has no edge or boundary in imaginary time. This would imply that the way the universe began was completely determined by the laws of science.
But the talented man who has produced such rich work suffers serious Amyotrophic Lateral Sclerosis (ALS) (肌萎縮性脊髓索硬化)。 He is one of the 350,000 sufferers in the world. The disease kills over 100,000 people every year."I like life and I love life, my family and music give me the greatest happiness,” smiled Hawking, who can only move three fingers.
In the coming year, Hawking said he is scheduled to write a new edition of A Brief History of Time for young children.
"A Brief History of Time is my first book for common people. But I later found that I could write it in a more simple way," he answered. "So I decided to rewrite it so that all people can read it easily. "

難點
1. Imagination is more important than knowledge．
想像力比知識更重要。
(1)在這個句子中，我們應(yīng)注意more…than．．．的正確理解，漢語意思為“比……更……”。
eg： He works more and better than he used to．
他的工作比過去做得更好。
Some students think chemistry is more interesting than physics．
有些學(xué)生認為化學(xué)比物理更有意思。
(2)另外more…than…還可譯作“與其……倒不如……”
eg：The child was more frightened than hurt．
這孩子的傷倒不算什么，只是受驚不小。
The book seems to be more a dictionary than a grammar．
這本書看來與其說是一本語法書，倒不如說是一本詞典。
2. It takes a very unusual mind t0 undertake analysis of the obvious．
分析明顯存在的事物需要非凡的頭腦。
(1)在這個句中take作“需要，要求”講。
eg：The journey from London to Oxford takes about an hour and a half．

她的病需要很長時間才能痊愈。
3．…they are studying something that is too large or too difficult to observe directly，…

too…to太……而不能／而沒有
eg：He is too angry to speak．他太生氣了，以致說不出話。
He went too late to see her．他去得太晚了而沒有見到她。
但是，該句型有時卻不表示否定，而表示肯定，有以下三種情況：
(1)如果too后為glad，pleased，happy，eager，anxious，willing，ready(甘心的、情愿的)，easy 等表示心情(情緒)的形容詞時，該句型表示肯定意義，這時too相當(dāng)于very。
eg：Mary is too willing to study Chinese．
瑪麗很愿意學(xué)習(xí)漢語。
The old man is too easy to get angry．
那個老頭很容易生氣。
(2)當(dāng)too前有副詞only，but，a11修飾時，該句型也表示肯定意義。這時only(but，a11)too相當(dāng)于very very，語氣較強。
eg：I shall be only too pleased to come．我將非常高興來。
We are but too glad to do s0．我們非常愿意這樣做。
(3)如果too前有否定詞never，not，即never／not too…to…的形式；或不定式前有not時，即too…not to do的形式，均表示肯定意義。
eg：This lesson is not too hard to understand．
這一節(jié)不太難，容易理解。
You are too clever not to learn English well．
你很聰明，能學(xué)好英語。
練習(xí)： He is careless find out all the errors in the composition．
A．too；to B．very；to
C．much；to D．rather；to
Grammar
一 不定式的用法
不定式由“to+動詞原形”構(gòu)成其否定形式是"not to do”。
不定式可以帶賓語或狀語構(gòu)成不定式短語，
沒有人稱和數(shù)的變化，但有時態(tài)和語態(tài)的變化。
to do 一般式
不定式的主動式有 to have done 完成式
to be doing 進行式
被動式最常用的是 to be done。
不定式的用法主要有：主語、賓語、表語、定語、賓語補足語、狀語,但不能作謂語。
1.作主語：不定式短語作主語時，往往放在謂語之后，用it作形式主語。 例：To see is to believe．
It is right to give up smoking．
It is a great pleasure to talk with him.
It is important for us to learn English well.
It is kind of you to help me so much.
注意：
要想說明不定式的動作是由誰發(fā)出，可在不定式前加for sb.；但如果是形容詞
careless, clever, foolish, good, impolite, kind, nice, silly, stupid 等作表語時用of sb.
2.作賓語：不定式短語作賓語時，如果還帶有賓語補足語，往往把不定式賓語放在賓語補足語之后，而用it作形式賓語。
eg：e wanted to go．
I find it interesting to work with him．
Most of them don't know how to solve the problem.
You can decide whether to stay at home or play football.
注意：
有些動詞后如：know, decide, find out, show, learn, teach, tell, wonder 常用 動詞+疑問詞+不定式 的形式。
3.作定語: 一般放在被修飾的名詞或代詞之后。
eg：I have some books for you to read．
注意：
(1)作定語的不定式如果是不及物動詞，或者不定式所修飾的名詞或代詞是不定式
動作的地點、工具等，不定式后面須有相應(yīng)的介詞。
eg：He is looking for a room to live in．
There is nothing to worry about．
Please give me a knife to cut with．
但是，不定式所修飾的名詞如果是time，place或way，不定式后面的介詞習(xí)慣上要省去。
eg：He had no money and no place to live．
(2)當(dāng)作定語的不定式所修飾的名詞或代詞是不定式動作的承受者時，不定式既可以用主動語態(tài)，也可用被動語態(tài)，但其含義有所不同。試比較：
(1)Have you anything to send? 你有什么東西要寄嗎?
(不定式to send的動作執(zhí)行者是you)
②Have you anything to be sent? 你有什么要(我或別人)寄的東西嗎?
(不定式to be sent的動作執(zhí)行者是已被省略的me或someone else)
4.作狀語: 表示目的、原因、結(jié)果或條件
eg：I came here to see you．(目的)
We were very excited to hear the news．(原因)
He hurried to the school only to find nobody there．(only to…常表示未曾料到的結(jié)果)
To look at him，you would like him．(條件)
注意：
(1) 目的狀語還可以用in order to或so as to來表示。
eg：In order to pass the exam, he worked very hard.
We ran all the way so as not to be late．
(2)不定式也可在作表語用的形容詞后面作狀語。
eg：I am very glad to hear it．
he question is difficult to answer．
(3)“too+形容詞或副詞+不定式”也作狀語。
eg：He is too old to do that．
另外句子中有enough這個詞時，常用不定式作狀語。
eg： The room is big enough to hold us．
5.作賓語補足語
eg：He asked me to do the work with him．
(1)在feel，hear，listen to，look at，notice，observe，see，watch，have，let，
make等詞后的補足語中，不定式不帶to，但是這些句子如果變成被動結(jié)構(gòu)時，就必須帶to。
eg: I often hear him sing the song．
He is often heard to sing the song．
(2)動詞不定式在介詞but，except，besides后面時,如果這些介詞之前有行為動詞do的各種形式，那么這些介詞后的不定式不帶to，否則要帶to。
eg：She could do nothing but cry．
What do you like to do besides swim?
I have no choice but to go．
6.作表語
eg：My job is to help the patient．
7.作獨立成分
eg： To tell the truth，I don't agree with you．
8.不定式與疑問詞who，which，when，where，how，what等連用，在句中起名詞作用，可充當(dāng)主語、表語、賓語等。
eg：He didn't know what to say．(賓語)
How to solve the problem is very important．(主語)
My question is when to start．(表語)
二 不定式的省略
在一定的語境中，為了避免重復(fù)，在某些詞語的后面不定式可省略，但不定式to通常不能省略。
1. 形容詞后不定式的省略。這類形容詞有：happy，gIad，ready，eager，anxious等。
如：I’ ll be away on a business trip．Would you mind looking after my cat?
Not at all。I’ d be happy to．
2. 賓語補足語、主語補足語中不定式的省略。這類動詞有l(wèi)agk，teIl，order，persuade，advise，wish，permit，allow等。
如：The boy wanted to ride his bicycle in the street, but his mother told him not to．
3. 動詞后不定式的省略。這類動詞有：like，love，hope，wish，mean，want，refuse，try，advise，persuade等。
如： Will you go to the theatre，Miss Brown?
Sorry．I don want to．
4. 在某些固定用法，如：ought to，have to，used to，be able to，be going to等后也可省略不定式。
如：一Alice，why didn’t you come yesterday?
一1 was going to，but I had an unexpected visitor．
注意：
有些動詞后既可接不定式，也可接動名詞，但含義不同。試比較：
go on doing sth．繼續(xù)干同一件事
go on to do sth．接著干另外一件事
stop doing sth．停止干某事
stop to do sth．停下來去干某事
forget doing sth．忘記已干了某事
forget to d0 sth．忘記要干某事
remember doing sth．記得已經(jīng)干了某事
remember to do sth．記住要干某事
try doing sth．試著干某事
try to do sth．設(shè)法干某事
mean doing sth．意味著干某事
mean to do sth．打算干某事
cant help doing sth．禁不住干某事
can't help(to)to sth．不能幫助干某事
regret doing sth．后悔干了某事
regret to do sth．因要做某事而感到遺憾
◇例題解析
1. She can’t help _______the house because she’s busy making a cake．
A．to clean B．cleaning
c．cleaned D．being cleaned (上海高考題)
[解析] 考查不定式作賓語。但不可因為思雛定勢的影響而選擇了B項。can’t help cleaning的意思是“忍不住要打掃”。與下文矛盾。本句句意是：她不能幫忙打掃房子，因為她忙于做蛋糕。can't help(to)do stll．表示“不能幫忙做某事”。[答案] A
2. When I handed the report to John，he said that George was the person______．(上海高考題)
A．to send B．for sending
C．to send it to D．for sending it to
[解析] 賓語從句還原則完成了send the report(it)to the person。當(dāng)它變成不定式作定語則成了the person to send it(the report)to。 for 引導(dǎo)的短語不可作定語。[答案] C
3. The purpose of new technologies is to make life easier，______ it more difficult．
A．not make B．not to make
C．not making D．do not make (全國高考題)
[解析] 所缺部分作目的狀語：(目的是)使生活變得更容易。再根據(jù)一致原則，前面用不定式作表語，后面也應(yīng)用不定式 作表語。[答案] B
4. Wang Tao was made_______ the dishes for a week as a punishment．
A．to wash B．washing C．wash D．to be washing
[解析] 不定式在使役動詞 make 后作賓語補足語時不帶to，但如果make變?yōu)楸粍诱Z態(tài),不定式就成了主語補足語，就須加上to。 [答案】 A
5. The chair looks rather hard，but in fact it is very comfortable to________.
A．sit B．sit on
C．be sat D．be sat on (全國高考題)
[解析] 不定式to sit on用作狀語，要用主動形式。sit為不及物動詞，故應(yīng)加上一個介詞on。[答案] B
6. 一--The light in the office is still on．
一-- 0h，I forgot_______．
A．turning it off B．turn it off
C．to turn it off D．having turned it off (全國高考題)
[解析] “我忘了關(guān)燈”，“關(guān)燈”這個動作并未發(fā)生.[答案] C
7. 一You were brave enough to raise objections at the meeting．
一 Well, now I regret_________ that．
A．t0 d0 B．to be doing
C．to have done D．having done (全國高考題)

8. 一 I usually go there by train．
一 Why not______ by boat for a change?
A. to going B．trying to go ‘
c. to try and go D．try going (全國高考題)
[解析] 對方建議為什么不換一種方式，乘船試一試。[答案] D
9.In some parts of London，missing a bus means______ for another hour．(2002年上海春季高考題)

[解析] mean doing sth．表示“意思是／意味著……”之意。[答案]A
10. We agreed______ here but so far she hasn't turned up yet．
A．having met B．meeting
C．to meet D．to have met (全國高考題)
[解析] agree后要求接不定式作賓語。[答案] C
11. Little Jim should 1ove________to the theatre this evening．
A．to be taken B．to take
C．being taken D. taking (全國高考題)
[解析] would like／love 后只接不定式，一般不能接動名詞。Jim 和take 間存在被動關(guān)系，故用不定式的被動形式。[答案] A
12. He gave me this strange object for my birthday and I don't know_______.
A．it what to do with B．what to do it with
C．what to do with it D．to do what with it
[解析] 該題考查名詞詞組作用的“疑問詞+不定式”的用法。根據(jù)句意和結(jié)構(gòu)，空白處應(yīng)填“疑問詞+不定式”結(jié)構(gòu)，作know的賓語。do with 在此意為“利用”、“使用”。[答案] c
13. She will tell us why she feels so strongly that each of us
has a role_______ in making the earth a better place to live．
A．to have played B．to play
C．to be played D．to be playing(2003年上海春招題)
[解析] 本題考查動詞不定式作后置定語的用法。這里是不定式作定語，修飾a role。但要注意不定式的不同形式表達不同含義。to have played表示完成；to be playing表示進行;play表示將來；to be played表被動關(guān)系。根據(jù)句意“她會告訴我們?yōu)槭裁此@樣強烈地感覺到：在使地球成為更美好的居住地中，我們每個人起到一定作用�！笔潜硎緦�。
再者要注意當(dāng)動詞不定式與所修飾的名詞之間為動賓關(guān)系，同時與句子主語為主謂關(guān)系時，動詞不定式用其主動形式表示被動意思，故排除c項。由題干從句中時態(tài)來看，為一般現(xiàn)在時(has arole)，故此處表示“起作用”，并非已完成的動作或正在起作用，故排除A、D兩項。[答案] B

答案
1.B 剖析：不定式放在句首作目的狀語。
2.D 剖析：要做好本題有兩點，一是pretend+to do，二是假裝的，是入睡的狀態(tài)。易誤：若弄不清是假裝入睡的動作還是狀態(tài)而誤選A。

4.C 剖析：先知道 manage to do sth．結(jié)構(gòu)，再者 get 是接賓補結(jié)構(gòu)。
5.C 剖析：定冠詞the+序數(shù)詞結(jié)構(gòu)后用不定式作定語。
6.B 剖析：本題考查的是不定式的否定式，在to前加not。
7.B 剖析：不定式作表語，且主語中有實意動詞 do 時，作表語的不定式中要省略 to。

9.C 剖析：要做對此題，必需具備的知識是rather than + 動詞原形，prefer to + 動詞原形。
10.B 剖析：make用于被動句時，要還原原來的to。易誤：若看見make就想到make sb．do sth．而想不到被動結(jié)構(gòu)的特殊性,則易誤選A.
