“Enough” with the multivitamins already. That’s the message from experts behind three new studies that tackled an often debated question: Do daily multivitamins多种维生素make you healthier?
“We believe that the case is closed - supplementing(补充) the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers. They urge consumers to not ‘waste’ their money on multivitamins. “The ‘stop wasting your money’ means that perhaps you’re spending money on things that won’t protect you long term,” editorial co-author, Dr. Edgar Miller said, “What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money.”
The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive(认知的) measures. The first study looked at vitamin supplementation’s role in preventing chronic(慢性的) disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. “The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo(安慰剂)-takers.” Dr. Edgar Miller stated.
One expert agreed some nutrient-deficient people may still benefit from multivitamins. “There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet,” Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant.

One night in March 1999, a man was driving from California to Oregon, US, to visit some friends. He had stopped his car to have some food when he started to hear strange noises. Turning on the headlights, he saw an 8-foot-tall creature covered in thick, dark hair. The creature stared at him for a minute, turned in the road and walked off slowly into the woods. 
In the past 50 years alone, there have been thousands of reported sightings of similar creatures in the US, Canada, the Himalayas(喜马拉雅山地区)and even Hubei Province in China. The creature is known as bigfoot.
Bigfoot is said to be a very tall(between 2 and 4. 5 metres), ape-like(类人猿似的)creature that is covered in hair and walks upright on two legs. It is very wary(警惕的)of human beings.
Believers think bigfoot is a direct descendent(后代)of ancient gigantopithecus(巨猿). But it remains one of the planet’s undiscovered secrets. There is a little evidence(证据)to support the believers’ theory: traces of hair, footprints and body prints as well as the reported sightings. Some people have even showed what they say with photos or films of bigfoot.
But so far, no one has found bones or any other definite proof that the giant creature exists.
As a result many people believe the evidence is just part of a big trick.
The footprints are easy to make and they say: all you need to do is to make two large feet out of plaster(石膏), attach them to the bottom of your shoes and walk with big steps. As for the photos and films, they are just people dressed in ape suits.
They also say the sightings are not real, just people making mistakes. For example, bigfoot could be a bear living in the wild that sometimes stands up on its back legs.
【小题1】 So far what we can be sure about is that .
| A．there exist savages(野人)in several places in the world |
| B．there are some traces of hair, footprints and body prints of the “bigfoot” |
| C．bigfoot is a direct descendent of ancient gigantopithecus |
| D．all the big foot discovered have the same look |
| A．1999 | B．the 1960’s |
| C．the 1950’s | D．the 1940’s |
| A．may fool the world into believing |
| B．have definite evidences to prove |
| C．refuse to believe |
| D．will soon offer proofs of |
| A．apes |
| B．bears |
| C．gigantopithecus |
| D．people dressed in animal skins |

Today just as technology changed the face of industry, farms have undergone an “agricultural revolution”. On the farm of today, machines provide almost all the power.
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.
【小题1】According to the passage, computers can NOT help farmers decide _______.
| A．what livestock to raise |
| B．whether to plant a certain kind of crop |
| C．how much money they can earn from their products |
| D．when to sell their products |
| A．Farmers in the future will depend totally on computers. |
| B．Both computers and robots have been in use on today’s farms. |
| C．Farmers mainly use machines on their farms at present. |
| D．Students at agricultural colleges must take computer classes because they can do nothing without the help of computers on today’s farms. |
| A．all farm work | B．milking cows |
| C．most of the farm work | D．some farm work |
| A．Computer, Farmers’ Best Friend |
| B．The Agricultural Revolution |
| C．Farmers in The Future |
| D．Computers and Robots |

The $11 billion self-help industry is built on the idea that you should turn negative thoughts like “I never do anything right” into positive ones like “I can succeed”. But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?
Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.
The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by citing (引证) older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better. If you tell your friend who is slow to learn that he has the potential of an Einstein, you’re just underlining his faults. In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write essays against funding for the disabled. When the essayists were later praised for their sympathy, they felt even worse about what they had written.
In this experiment, Wood, Lee and Perunovic measured 68 students’ self-esteem (自尊). The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, “I am lovable.”
Those with low self-esteem didn’t feel better after the forced self-affirmation (自我肯定). In fact, their moods turned significantly darker than those of members of the control group, who weren’t urged to think of positive thoughts.
The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation (静思) techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic viewpoint. Call it the power of negative thinking.
【小题1】The first paragraph is written _________.
| A．to raise an argument about positive thinking |
| B．to introduce the power of positive thinking |
| C．to encourage people to have positive thoughts |
| D．to introduce the $11 billion self-help industry |
| A．positive thinking is not as powerful as negative thinking |
| B．encouraging positive thinking may actually discourage people |
| C．happy people can think positively while unhappy people can’t |
| D．getting people to think positively can strengthen their confidence |
| A．You are pointing out the mistakes he has made. |
| B．You are reminding him that he is not intelligent. |
| C．You are not taking his mistakes seriously enough. |
| D．You are showing he has great potential in spite of faults. |
| A．negative feelings must be got rid of |
| B．there’s no point in thinking positively |
| C．it doesn’t make sense to think negatively |
| D．negative thinking is not always negative |

Our body clock，or natural body rhythm，influences our energy and alertness．Paying attention to it can help us choose the suitable time of day when we best perform specific tasks．
The reality，however，is that most of us organize their time around work demands，school deadlines，commuting or social events．Doing whatever your body feels like doing is a luxury in today's fast-paced modem society．
But that doesn't mean it isn't worth trying．Obeying our body clock has significant health benefits．Disrupting our natural body rhythm，on the other hand，has been linked to problems such as depression，obesity，or headache，says Steve Key，a biology professor．
When the body clock can synchronize（使……同步）the rhythms of its natural processes，it “gives us an advantage in daily life”，says Key．
According to him，when it comes to cognitive（认知的）work，most adults perform best in the late morning．As our body temperature starts to rise just before awakening in the morning and continues to increase until midday，our memory，alertness and concentration gradually improve．
However，he adds，our ability to concentrate typically starts to decrease soon thereafter．Most of us are more easily distracted（分心）between noon and 4 pm．
Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm，making that a good time for a nap．
Surprisingly, tiredness may increase our creative powers．For most adults，problems that require open ended thinking are often best dealt with in the evening when they are tired， according to a study in the journal Thinking & Reasoning．
When choosing a time of day to exercise，paying attention to your body clock can improve results．Physical performance is usually best from about 3 to 6 pm，says Michael Smolensky，a professor of biomedical engineering．
Of course, not everyone's body clock is the same，making it even harder to synchronize natural rhythms with daily plans．
【小题1】If we know our natural body rhythm well, we can ．
| A．find out the suitable time to do specific tasks |
| B．organize our time around work demands |
| C．do whatever our body feels like doing |
| D．be sure to be healthy |
| A．Our alertness is influenced by our natural body rhythm |
| B．Doing whatever your body feels like is very difficult in our modem society． |
| C．Obeying our body clock is good for our health． |
| D．Disrupting our natural body rhythm can lead to obesity． |
| A．When our body clock synchronizes the rhythms of its natural processes，we can do better． |
| B．When it comes to cognitive（认知的）work，most people perform best in the late morning． |
| C．As body temperature rises before awakening in the morning，our concentration gradually improves． |
| D．We concentrate better in the late morning than between noon and 4 pm． |
| A．when we get up in the morning |
| B．when we are tired in the evening |
| C．when we are full of energy in the late morning |
| D．when we are asleep at night |
| A．What is natural body rhythm? |
| B．Natural body rhythm is good for us． |
| C．Something about natural body rhythm． |
| D．The latest research about natural body rhythm． |

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
【小题1】The biggest difficulty in operating on the damaged brain is that _______.
| A．the time is too short for doctors |
| B．the patients are often too nervous |
| C．the damage is extremely hard to fix |
| D．the blood-cooling machine might break down |
| A．taking the blood out of the brain |
| B．trying the operation on monkeys first |
| C．having the blood go through a machine |
| D．lowering the brain' s temperature |
| A．can last as long as 30 minutes |
| B．can keep the brain' s blood warm |
| C．can keep the patient' s brain healthy |
| D．can help monkeys do different jobs |

Mass transportation revised the social and economic fabric of the American city in three fundamental ways. It catalyzed physical expansion, it sorted out people and land uses, and it accelerated the inherent instability of urban life. By opening vast areas of unoccupied land for residential expansion, the omnibuses, horse railways, commuter trains, and electric trolleys pulled settled regions outward two to four times more distant form city centers than they were in the premodern era. In 1850, for example, the borders of Boston lay scarcely two miles from the old business district; by the turn of the century the radius extended ten miles. Now those who could afford it could live far removed from the old city center and still commute there for work, shopping, and entertainment. The new accessibility of land around the periphery of almost every major city sparked an explosion of real estate development and fueled what we now know as urban sprawl. Between 1890 and 1920, for example, some 250,000 new residential lots were recorded within the borders of Chicago, most of them located in outlying areas. Over the same period, another 550,000 were plotted outside the city limits but within the metropolitan area. Anxious to take advantage of the possibilities of commuting, real estate developers added 800,000 potential building sites to the Chicago region in just thirty years – lots that could have housed five to six million people.
Of course, many were never occupied; there was always a huge surplus of subdivided, but vacant, land around Chicago and other cities. These excesses underscore a feature of residential expansion related to the growth of mass transportation: urban sprawl was essentially unplanned. It was carried out by thousands of small investors who paid little heed to coordinated land use or to future land users. Those who purchased and prepared land for residential purposes, particularly land near or outside city borders where transit lines and middle-class inhabitants were anticipated, did so to create demand as much as to respond to it. Chicago is a prime example of this process. Real estate subdivision there proceeded much faster than population growth.

[A] Types of mass transportation.
[B] Instability of urban life.
[C] How supply and demand determine land use.

【小题2】Why does the author mention both Boston and Chicago?
[A] To demonstrate positive and negative effects of growth.
[B] To exemplify cities with and without mass transportation.
[C] To show mass transportation changed many cities.
[D] To contrast their rate of growth.
【小题3】According to the passage, what was one disadvantage of residential expansion?
[A] It was expensive.
[B] It happened too slowly.
[C] It was unplanned.
[D] It created a demand for public transportation.
【小题4】The author mentions Chicago in the second paragraph as an example of a city,
[A] that is large.
[B] that is used as a model for land development.
[C] where the development of land exceeded population growth.
[D] with an excellent mass transportation system.

Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex.
In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent.
The study's participants were tested on science, maths, English and mechanical abilities.
Though there were twice as many men as women in the smartest group, there were also twice as many men among the dolts.
The aggregate scores of men and women were similar.
One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their home.
"The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying.
The research tallies with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds.
It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning.
A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds.
The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach.
【小题1】The purpose of the passage is to tell us that ________.
| A．man are smarter then women |
| B．man are more stupid the women |
| C．a new fact about the IQ of men and women has been found |
| D．men are more likely to receive first class university degrees |
| A．they are born stupid |
| B．they have to spend more time to tale care of their home than men |

The art of reading fiction is largely a matter of inferring meanings. To infer means to understand facts which are not directly stated---only suggested. Inference is one of the commonest ways of knowing things: a child holds his knee and cries; this action implies his feeling; an observer infers that the child is hurt. To infer accurately in everyday life requires caution in observing; to infer skillfully in fiction requires caution in reading; both require disciplined imagination.
The short-story reader can expect to find certain basic elements in any story. For example, all stories involve a person or persons, in a particular setting, faced with a demand for a response. The response called for may be a physical action, such as defeating an adversary(对手) or escaping from a danger; or it may be a mental action, such as adjusting to others or within oneself. In either case, the short story is a description in two ways: first, it shows the motives for a given human action; second, it makes a point about the general human situation. Such descriptions, however, rather than being stated directly, usually are implied by the elements of the story.
When the reader of a story understands all the facts and their interrelationships, he is ready to infer the significance of the story as a whole---its comment on the human situation. This comment, or theme, is the seed from which the story grew. It is also the idea by which all the separate elements of the story are governed, while these in turn further shape and modify the theme. In addition to action, character, and setting, these elements include structure, mood, tone, and point of view.
Fiction reading requires an awareness of all the ways in which a story communicates. It also requires attention to detail. What the author provides is a network of points which serve as clues to his meaning. He invites the reader to develop the meaning by inference, actually to create much of the story himself and so make it part of his own experience.
【小题1】According to the author, "infer" means ________ .
| A．knowingfactsbeyondthestatement |
| B．lookingformoreevidencesforthestatement |
| C．findingoutadifferentmeaningfromthestatement |
