Everyone becomes a little more forgetful as they get older, but men's minds decline more than women's, according to the results of a worldwide survey.
Certain differences seem to be inherent in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning<推論;說服> and spatial <空間的>skills), while women tend to excel (擅長) at recalling information from their brain's files (helpful with language skills and remembering the locations of objects).
Many studies have looked for a connection between sex and the amount of mental decline (衰退) people experience as they age, but the results have been mixed.
Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline. Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, "so they're the ones that may not have shown such cognitive(認(rèn)知的;認(rèn)識的) decline," said study team leader Elizabeth of the University of Warwick in England.
People surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated(旋轉(zhuǎn)的) form, matching lines shown from the same angle, typing as many words in a particular category (范疇) as possible in the given time, e.g.  "object usually colored gray", and recalling the location of objects in a line drawing. The first two were tasks at which men usually excel; the latter are typically dominated(占有主導(dǎo)地位的) by women.
Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders(性別), women showed obviously less decline than men overall(全部地).
小題1:The underlined word in the second paragraph means_________.
A.naturalB.greatC.obviousD.a(chǎn)bsolute
小題2:According to the passage, which of the following can Not be typed into the same category?

D.Women excel at dealing mathematic problems.
小題4: One important factor that affects the correctness of the results is that _________.
A.the old men tested may not have shown such cognitive decline
B.people surveyed are all old
C.people taking part in this test came from all over the worldD.women live longer than men
小題5:The author aims to tell us that __________.
A.women’s minds perform better than men’s
B.men’s minds decline more with age
C.everyone becomes a little more forgetful as they get older

Imagine a training course that helps you in your specific job. Imagine tools and techniques that are so closely connected with your work that you can apply them directly to it. Imagine receiving an Open University (OU) certificate (證書) in a course which states what you have studied and achieved.
It may sound fantastic, but it’s a reality at the Open University’s CCPD, which is making learning while you work more flexible (靈活的) than ever before.
The courses are starting to change workplace learning completely. Paige, who took CCPD’s courses, said the study had changed her whole way of thinking. “It was excellent for so many reasons,” she said. “It developed me as a person and as an employee and taught me particular techniques. I was always able to bring what I’d learned into the office the next day and apply it to my job.”
Even better news for Paige was that her employer paid the full cost of her study. She became one of thousands of OU students whose fees were paid by employers who recognized the value of an OU education.
“These courses are designed for CCPD rather than as part of a formal certificate,” said Kathy, an OU teacher. “We pay more attention to development rather than assessment (評估). Our role is to give them personal developmental advice, not a mark.”
Paige is just one of 200,000 students who are learning at OU. CCPD itself is just a part of an organization that offers courses and qualifications in 360 subjects and has so far helped to develop the skills and knowledge of more than two million people.
“Education does not stop with getting a degree,” said Charles Edwards, CCPD’s director. “In a fast-moving economy you cannot afford to rely on the degree you got some time ago. You must keep updating your knowledge.”
For details on CCPD’s courses and to register with the 10% discount available to members, visit www.open.ac.uk.
小題1:According to the passage, CCPD’s courses are ________.
A.required courses for formal academic qualifications

Few people would defend the Victorian attitude on children, but if you were a parent in those days, at least you knew where you stood: children were to be seen and not heard. Freud and his colleagues did away with all that and parents have been puzzled ever since. The child’s happiness is all- important, they say, but what about the parents’ happiness? Modern child-rearing manuals(撫養(yǎng)孩子手冊)would never permit cruelty to children .The trouble is you are not allowed even to shout. Who knows what deep psychological(心理的)wounds you might cause? The poor child may never recover from the dreadful experience. So it is the parents that bend over backwards to avoid giving their children complex which a hundred years ago hadn’t even been heard of. Certainly, a child needs love, and a lot of it. But the excessive permissive(縱容) of modern parents is surely doing more harm than good.
Psychologists(心理學(xué)家) have succeeded in weakening parents confidence in their own authority. And it hasn’t taken children long to get wind of the fact. In addition to the great modern classics on child care, there are countless articles in magazines and newspapers. With so much advice flying about, mum and dad just don’t know what to do any more. In the end, they do nothing at all. So, from early childhood, the kids are in charge and parents’ lives are regulated according to the needs of their kids. When the little dears develop into teenagers, they take complete control. Lack of authority over the years makes teenagers rebellion against parents all the more violent. If the young people are going to have a party, for example, parents are asked to leave the house. Their presence merely spoils the fun. What else can the poor parents do but obey?
小題1:The author says that today’s parents _______.
A.a(chǎn)re bombarded with excessive amounts of child-care literature.
B.draw a distinction between permissiveness and carelessness.
C.a(chǎn)re only towards children from happy home backgrounds.
D.weigh their children’s knowledge rather than intelligence.
小題2:The phrase “get wind of” (Para.2) most likely means _______ .
A.become used toB.try to avoid
C.realizeD.become puzzled of
小題3:Which of the following can be inferred from this passage?
A.Victorian child rearing is a model for parents to follow.
B.Psychologists have much to answer for today’s problems on child care.
C.With the help of so much advice, raising children is easier than ever.
D.Parents like to enjoy the freedom when there is a party in the house.
小題4:What’s the main idea of this passage?
A.The excessive permissiveness of today’s parents is harmful to children.
B.Psychologists shouldn’t interfere so much with child care.
C.Parents should hold the Victorian attitudes towards children.
D.Children are too sensitive to be hurt.

The United States government wants to know what the public thinks about its findings on the safety of cloned animals.
The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An F.D.A. official called them "as safe to eat as the food we eat every day." And when those clones reproduce sexually(有性繁殖), the agency says, their offspring(后代) are safe to eat as well. But research on cloned sheep is limited. So the F.D.A. proposes that sheep clones not be used for human food.
The United States this year could become the first country to approve the sale of foods from cloned animals. First, however, the public will have ninety days to comment on three proposed documents. On December 28th the F.D.A. released a long report, called a draft risk assessment, along with two policy documents.
The agency says it must receive comments by April second. The F.D.A. seemed ready to act several years ago, but an advisory committee called for more research.
For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.
Clones are still rare. They cost a lot and are difficult to produce.
The F.D.A. says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.
Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about cloning.
Cloning differs from genetic engineering. A cell taken from a so-called donor animals is grown into an embryo(胚胎)in the laboratory. Next, the embryo is placed into the uterus(子宮)of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.
小題1:From the passage we know that               .
A.foods from cloned animals are popular in America
B.cloned adult animals are safe to eat except sheep.
C.cloned animals will be easy to produce
D.most foods from cloning is expected to take place of other foods
小題2:The main purpose of the text is to               .

小題3:Who believe that foods from cloning are safe to eat?
A. Most Americans     B. An advisory committee
C. Critics             D. The F.D.A.
小題4:It can be inferred from the last paragraph that         .

Why did humans evolve to walk upright? Perhaps because it’s just plain easier. Make that “energetically less costly”, scientifically speaking.
Bipedalism—walking on two feet, is one of the defining characteristics of being humans, and scientists have debated for years how it came about. In the latest attempt to find an explanation, researchers trained five chimps(黑猩猩)to walk on a treadmill(跑步機(jī))while wearing masks that allowed measurement of their oxygen consumption. The chimps were measured both while walking upright and while moving on their legs and knuckles(膝關(guān)節(jié)).That measurement of the energy needed to move around was compared with similar tests on humans and the results are published in this week’s online edition of “Proceedings of the National Academy of Sciences”.
It turns out that humans walking on two legs use only one-quarter of the energy that chimps use while knucklewalking on four limbs(肢).And the chimps, on average, use as much energy using two legs as they did when they used all four limbs.
However, there were differences among chimps in how much energy they used, and this difference corresponded to their different manner of walking and anatomy(解剖構(gòu)造).One of the chimps used less energy on two legs, one used about the same and the others used more, said David Raichlen, assistant professor of anthropology at the University of Arizona.
“What we were surprised at was the variation(變異) ”, he said in a telephone interview. Interview. “That was pretty exciting, because when you talk about how evolution works, variation is the bottom line, without variation there is no evolution.”
Walking on two legs freed our arms, opening the door to drive the world, said Raichlen. “We think about the evolution of bipedalism as one of first events that led hominids(原始人)down the path to being humans.”
The research was supported by the National Science Foundation and the L.S.B.Leakey Foundation.
小題1: The underlined word “Bipedalism” in Paragraph 2 probably means____.
A.moving sidewaysB.walking upright
C.walking on four legsD.running fast
小題2:We can infer from the passage that____.
A.scientists have no idea on how humans’ walking on two legs came about
B.scientists have had different views on why chimps walk on four legs
C.scientists have had different views on how humans’ walking on two legs vame about
D.scientists have had similar views on how humans’ walking on two legs came about
小題3:What is Paragraph 4 mainly about?
A.How chimps saved energy.
B.Why chimps didn't walk on two legs.
C.David Raichlen studied chimps.
D.Different chimps consumed different energy.
小題4: According to the passage, humans walk upright in order to____.
A.conserve energyB.differ from other animals

Contribution of Coeducation
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.
小題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.
小題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.
小題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.
小題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.

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.
When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered(轉(zhuǎn)基因的) trees.
Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.
Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.
Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
The Pentagon (五角大樓) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack..
So far, the poplar, eucalyptus (楊樹與桉樹), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes(基因組).
However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.
"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.
They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.
小題1:What trees are NOT the ones that scientists are planting in the US?
A.Trees that worms can't hurt.
B.Trees that can protect themselves at a chemical attack.
C.Trees that can resist wind better.
D.Trees that can improve soil conditions.
小題2:What caused the American scientists to work on special trees?
A.They think science could give nature a fighting chance against both natural and man-made dangers.
B.Great numbers of trees have been lost due to attacks by viruses.
C.Researchers successfully introduced seeds designed to resist the virus.
D.Tree genomes are mapped out so scientists know how to improve trees.
小題3:Which of the following was probably the first kind of trees being engineered?
A.Papaya.B.Pine.C.Apple. D.Poplar.
小題4:The best title of the passage is         .
A.The improvement of environment
B.The side-effects of special trees
C.The development of special trees

Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush. Through her own efforts, her letter was reproduced on over 250 donated billboards across the country.
The response to her request for help was so huge that Poe established Kids For A Cleaner Environment (Kids F.A.C.E.) in 1989. There are now 300,000 members of Kids FACE worldwide and is the world's largest youth environmental organization.
Poe has also asked the National Park Service to carry out a "Children's Forest" project in every national park. In 1992, she was invited as one of only six children in the world to speak at the Earth Summit in Brazil as part of the Voices of the Future Program. In 1993, she was given a Caring Award for her efforts by the Caring Institute.
Since the organization started, Kids F.A.C.E. members have distributed and planted over 1 million trees! Ongoing tree-planting projects include Kid's Yards – the creation of backyard wildlife habitats (棲息地) and now Kids F.A.C.E. is involved in the exciting Earth Odyssey, which is a great way to start helping.
"Starting the club turned out to be a way to help people get involved with the environment. Club members started doing things like recycling, picking up litter and planting trees as well as inviting other kids to join their club."
"We try to tell kids that it's not OK to be lazy," she explains. "You need to start being a responsible, environmentally friendly person now, right away, before you become a resource-sucking adult."
