The branch of chemistry that studies and finds ways to use raw materials from farm products to make industrial products is called chemurgy. Carver was one of the first and greatest chemurgists of all time. Today the science of chemurgy is better known as the science of synthetics(合成纤维织物). Each day people depend on and use synthetics made from raw materials. All his life Carver battled against the disposal of waste materials, and warned of the growing need to develop substitutes(代用品) for the natural substances being used up by humans.
Carver never cared about getting credit for the new products he created. He never tried to patent(申请专利) his discoveries or get wealthy from them. He turned down many offers to leave Tuskegee Institute to become a scientist in private industry. Thomas Edison, inventor of the electric light, offered him a laboratory in Detroit to carry out food research. When theUnited States government made him a collaborator in the Mycology and Plant Disease Survey of the Department of Agriculture, he accepted the position with the understanding that he wouldn’t leave Tuskegee. An authority on plant disease—especially of the fungus(真菌) variety—Carver sent hundreds of specimens(标本) to the United States Department of Agriculture. At the peak of his career, Carver’s fame and influence were known on every continent.

举一反三
Imagining being asked to spend twelve or so years of your life in a society which consisted only of members of own sex. How would you react? Unless there was something definitely wrong with you, you wouldn’t be too happy about it, to say the least. It is all the more surprising therefore that so many parents in the world choose to impose such abnormal conditions on their children – conditions which they themselves wouldn’t put up with for one minute!
Any discussion of this topic is bound to question the aims of education. Stuffing children’s heads full of knowledge is far from being foremost among them. One of the chief aims of educations is to equip future citizens with all they require to take their place in adult society. Now adult society is made up of men and women, so how can a segregated school possibly offer the right sort of preparation for it? Anyone entering adult society after years of segregation can only be in for a shock.
A co-educational school offers children nothing less than a true version of society in miniature. Boys and girls are given the opportunity to get to know each other, to learn to live together from their earliest years. They are put in a position where they can compare themselves with each other in terms of academic ability, athletic achievement and many of the extra-curricular activities which are part of school life. What a practical advantage it is ( to give just a small example ) to be able to put on a school play in which the male parts will be taken by boys and the female parts by girls! What nonsense co-education makes of the argument that boys are cleverer than girl or vice-versa. When segregated, boys and girls are made to feel that they are a race apart. Rivalry between the sexes is fostered. In a coeducational school, everything falls into its proper place.
But perhaps the greatest contribution of co-education is the healthy attitude to life it encourages. Boys don’t grow up believing that women are mysterious creatures – airy goddesses, more like book-illustrations to a fairy-tale, than human beings. Girls don’t grow up imagining that men are romantic heroes. Years of living together at school dispel illusions of this kind. There are no goddesses with freckles, pigtails, piercing voices and inky fingers. There are no romantic heroes with knobby knees, dirty fingernails and unkempt hair. The awkward stage of adolescence brings into sharp focus some of the physical and emotional problems involved in growing up. These can better be overcome in a co-educational environment. Segregated schools sometimes provide the right conditions for sexual deviation. This is hardly possible under a co-educational system. When the time comes for the pupils to leave school, they are fully prepared to enter society as well-adjusted adults. They have already had years of experience in coping with many of the problems that face men and women.
小题1:What is the best title for this passage?
A only co-education can be in harmony with society.
B people are in great need of co-education.
C any form of education other than co-education is simply unthinkable.
D co-education has many features.
小题2:what does co-education offer to children?
A A society. B A true small model of society.
C A real life. D True version of social condition.
小题3:According to the passage, what is one of the chief aims of education?
A It is for students to acquire knowledge.
B It is to equip future citizens with scientific technology.
C It is to equip future citizens with what is required in getting a position in society.
D It is for students to get academic achievements.
小题4:Why do boys and girls in co-education have no illusion about each other?
A They live together and know each other too well.
B Years of living together at school dismiss such illusion.
C co-education encourage them to have an healthy attitude toward life.
D They are familiar with each other’s problems.
But things could start to get better soon. The government is co-operating with a US-based environmental protection agency to update existing buses and trucks with clean fuel technology. The new technology could reduce air pollutants in existing diesel vehicles (柴油机) by 40 per cent. The programme will begin by testing buses in Beijing to see if the technology can be applied to them.
“We encourage the development of public transportation. But at the same time we need to reduce pollution from them,” said an official.
Efforts are being made to improve the capital’s environment with tighter controls on emissions (排放). Some heavily polluting factories and construction sites, such as those owned by the steel giant Shougang Group, have been asked to cut production in November and December or be closed.
Beijing was the third polluted city in the world at the end of last century, according to the UN. But thanks to recent measures, the capital has made some progress. Last year 224 clear days were rated as having good air quality. In 1998 the air quality index (指数) gave just 100 days as good.
“I am glad to see an improvement,” said a Senior 1 boy living in the northwest of Beijing. “Compared to other places, the air quality of Beijing is still worrying though. I hate the pollution. Once I was riding my bike in the morning when I almost had a traffic accident because I couldn’t see a car only metres away from me in frog.”
In early October, the skies were covered by such a thick fog that a display show by the visiting French air force was called off.
Rapid development, industry, traffic fumes (烟) and sandstorms from the desert all contribute to the city’s bad air.
小题1:The passage is mainly about ________?
| A．a programme to improve Beijing’s air quality |
| B．progress made in Beijing’s air quality |
| C．Beijing’s air pollution |
| D．the difference between Hainan and Beijing |
| A．Clean fuel technology will be used in public transportation. |
| B．Some factories have been asked to cut production. |
| C．Some construction sites have been told to be closed. |
| D．A display show of airplanes has been called off. |
| A．far more still needs to be done |
| B．nothing else needs to be done |
| C．all traffic has to be closed |
| D．the development of the city has to be slowed down |
| A．Beijing’s air quality is getting worse and worse. |
| B．Development, industry, traffic fumes and sandstorms are all the causes of bad air quality. |
| C．Clouds of smoke in the sky is the common feature in the winter of Beijing. |
| D．The government is making every effort to stop air pollution. |
If proved by DNA evidence, the theory will break long established beliefs about the southerly migration of people who entered America across the Bering Strait, found it empty and occupied it.
On this theory rests the belief of Native Americans to have been the first true Americans. They would be classified to the ranks of escapee, beaten to the New World by Aboriginals (土著人) in boats.
To a European, this may seem like an academic argument, but to Americans it is a philosophical question about identity, Silvia Gonzales, of Liverpool University said .
Her claims are based on skeletons found in the California Peninsula of Mexico that have skulls quite unlike the broad Mongolian features of Native Americans. These narrow-skulled people have more in common with southern Asians, Aboriginal Australians and people of the South Pacific Region.
The bones, stored at the National Museum of Anthropology (人类学) in Mexico City, have been carbon-dated and one is 12,700 years old, which places it several thousand years before the arrival of people from the North. “We think there were several migration waves into the Americas at different times by different human groups,” Dr. Gonzales said. “The timing, route and point of origin of the first colonization of the Americas remains a most contentious topic in human evolution.”
But comparisons based on skull shape are not considered conclusive by anthropologists, so a team of Mexican and British scientists, backed by the Natural Environment Research Council, has also attempted to take out DNA from the bones. Dr. Gonzales declined yesterday to say exactly what the results were, as they need to be checked, but indicated that they were consistent(一致) with an Australian origin.
小题1:It is generally considered that the first Native Americans came from ________.
| A．North Asia | B．Australia |
| C．South Pacific | D．South Asia |
| A．the broad skull shape |
| B．the narrow skull shape |
| C．different features of Aboriginal Australians |
| D．the same features of Native Americans |
| A．likely to cause great interest | B．difficult to solve |
| C．well-known to all | D．likely to cause argument |
| A．Research on skulls can draw an exact conclusion. |
| B．DNA tests have proved the fact that the first Native Americans came from Australian. |
| C．Scientists are still not sure about the origin of the Native Americans. |
| D．People began to enter America across the Bering Strait about 12,700 years ago. |
The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image(印象)of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.” We were surprised by just how positive today’s young people seen to be about their families,” said one member of the research team.” They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation(商议) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends.” My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall.” I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.”Susan Crome, who is now 21, agrees.”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework ,I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers’ rebellion is not rooted in real facts. A researcher comments,” Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”
小题1:What is the popular images of teenagers today?
| A．They worry about school | B．They dislike living with their parents |

| A．go to clubs more often with their children | B．are much stricter with their children |
| C．care less about their children’s life | D．give their children more freedom |
| A．may be a false belief | B．is common nowadays |
| C．existed only in the 1960s | D．resulted from changes in families |
| A．Negotiation in family | B．Education in family |
| C．Harmony in family | D．Teenage trouble in family |
One advantage of the essay test is that it reduces the element of luck. The student cannot get a high score just by making a lucky guess. Another advantage is that it shows the examiner more cares about the student’s ability to put facts together into a meaningful whole. It should show how deeply he has thought about the subject. Sometimes, though, essay tests have disadvantages, too. Some students are able to write rather good answers without really knowing much about the subject, while other students who actually know the material have trouble expressing their ideas in the essay form.
Besides, in an essay test the student’s score may depend upon the examiner’s feelings at the time of reading the answer. If he is feeling tired or bored, the student may receive a lower score than he should. Another examiner reading the same answer might give it a much higher mark. Because of this, the objective test gives each student a fairer chance, and of course it is easier and quicker to score.
Whether an objective test or an essay test is used, problems arise. When some objective questions are used along with some essay questions, however, a fairly clear picture of the student’s knowledge can usually be gotten.
小题1:What may have been discussed in the previous paragraphs?
| A．The essay test. | B．How teachers test their students. |
| C．How students write their essays. | D．The objective test. |
| A．it shows more about the student’s understanding of the subject |
| B．it tests the student’s knowledge of the material as well as his expression of ideas |
| C．it gives each student a fairer chance |
| D．its scoring may be influenced by the examiner’s feelings |
| A．students may receive a lower score in an essay test |
| B．another examiner usually gives the answer a higher mark |
| C．different examiners may give the same essay different scores |
| D．the objective test gives each student a fairer chance |
| A．It is more objective than the essay test in terms of scoring. |
| B．It allows the student to guess the correct answer without really knowing the material. |
| C．It shows the student’s ability to think about difficult problems. |
| D．It is easy and quick to score. |
