共用题干第三篇Boys' schools are the perfect place to teach young men to express their emotions and are more likely to get involved in activities such as art,dance and music,according to research released today.Far from the traditional image of a culture of aggressive masculinity,the absence of girls gives boys the chance to develop without pressure to conform to a stereotype,the U.S. study says.Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness,rather than feeling they had to conform to the "boy code" of hiding their emotions to be a "real man".The report,presented at a conference of the International Boys' Schools Coalition in London attended by the heads of private and state schools,goes against received wisdom that boys do better when taught alongside girls.The headmaster of Eton,Tony Little,warned that boys were being failed by the British education system because it had become too focused on girls.He criticised teachers for failing to recognise that boys are actually more emotional than girls,despite the fact that girls"turn on the waterworks".The research argued that boys often perform badly in mixed schools because they become demoralised when their female counterparts do better earlier in verbal skills and reading,because the left side of the brain develops faster in girls.They also felt they had to be"cool"rather than studious. But in single-sex schools teachers are able to tailor lessons to boys' learning style,letting them move around the classroom and getting them to compete in teams to prevent boredom,wrote the study's author,education expert Abigail James,of the University of Virginia.Teachers could encourage boys to enjoy reading and writing with specifically"boy-focused" approaches such as themes and characters that appeal to them. Because,the researchers say,boys generally have better spatial skills,more acute vision,learn best through touch,are more impulsive and more physically active,they need to be given "hands-on" lessons where they are allowed to walk around." Boys in mixed schools view classical music as feminine and prefer the modern genre in which violence and sexism are major themes,"James wrote.Single-sex education also made it less likely that boys would feel they had to conform to a stereotype gained from the media by girls that men should be "masterful and in charge" in relationships. "in the present sexualised atmosphere prevalent in mnixed schools,boys feel coerced into acting like men before they understand themselves well enough to know what that means,"the report said.What does Tony Little say about the British education system?A:It fails more boys than girls academically.B:It focuses more on mixed school education.C:It fails to give boys the attention they need.D:It places more pressure on boys than on girls.

共用题干Teaching Math,Teaching AnxietyIn a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn:If a female teacher is uncomfortable with her own math skills,then her female students are more likely to believe that boys are better than girls at math.If these girls keep getting math-anxious female teachers in later grades,it may create a snowball effect on their math achievement said Levine. In other words,girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident.Just as students find certain subjects to be difficult,teachers can find certain subjects to be difficult to learn一and teach. The subject of math can be particularly difficult for everyone. Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.The new study found that when a teacher has anxiety about math,that feeling can influence how her female students feel about math. The study involved 65 girls,52 boys and 17 first-and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year,and the researchers compared the scores.The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math,such as when reading a sales receipt. A teacher who got nervous looking at the numbers on a sales receipt,for example,was probably anxious about math.Boys,on average,were unaffected by a teacher's anxiety. On average,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety.“This is an interesting study,but the results need to be interpreted as preliminary and in need of replication with a larger sample,”said David Geary,a psychologist at the University of Missouri in Columbia.David Geary thinks that______.A: the study is interesting but it is based on unreliable research processB: the research results need to be retested based on a larger sampleC: the research results need to be reinterpreted to be meaningfulD: the study is well based and produces significant results

共用题干第三篇 Smart ExerciseDoctors are starting to find more and more information that suggests a connection between exercise and brain development.Judy Cameron,a scientist at Oregon Health and Science University,studies brain development.According to her research,it seems that exercise can make blood vessels,including those in the brain,stronger and more fully developed.Dr. Cameron claims this allows people who exercise to concentrate better. As she says:"While we already know that exercise is good for the heart,exercise can literally cause physical changes in the brain."The effects of exercise on brain development can even be seen in babies.Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active.With babies,even a{ittle movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in the importance of exercise.She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses.They need to establish a connection between motion and memory.In this way,as they get older,children will begin to associate physical activity with higher learning,"says Margaret. Older people can beef up their brains as well.Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week.The exercise does not have to be very difficult,but it does have to increase the heart rate.Also,just like the motion for infants,exercise for older people should involve some complexity.Learning some new skills or motions helps to open up memory paths in the brain that may not havebeen used for a long time.For most people,any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood.And your brain can benefit from as little as two to three hours of exercise a week. Research by Dr.Cameron seems to suggest that exercise canA: generate new blood vessels. B:change the way a person thinks.C: promote brain development. D: divert one's attention.

Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.The new study found that when a teacher has anxiety about math,that feeling can influence how her female students feel about math. The study involved 65 girls,52 boys and 17 first-and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year,and the researchers compared the scores.The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math,such as when reading a sales receipt. A teacher who got nervous looking at the numbers on a sales receipt,for example,was probably anxious about math.Boys,on average,were unaffected by a teacher's anxiety. On average,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety.“This is an interesting study,but the results need to be interpreted as preliminary and in need of replication with a larger sample,”said David Geary,a psychologist at the University of Missouri in Columbia.What is implied in the third paragraph?A: Math teachers,like math learners,do not like the subject due to its difficulty.B: A difficult subject like math may affect teachers'confidence in teaching the subject.C: Teachers are more anxious teaching math than their students learning math.D: Math is so difficult that no teachers like to teach it.
共用题干第二篇Where Have All the Frogs Gone?In the 1980s,scientists around the world began to notice something strange:Frogs were disappearing. More recent research has shown that many kinds of amphibians（两栖动物）are declining or have become extinct. They have been around for a long time一over 350 million years.Why are they dying out now?Scientists are seriously concerned about this question.First of all,amphibians are an important source of scientific and medical knowledge.By studying amphibians,scientists have learned about new substances that could be very useful for treating human diseases. Further research could lead to many more discoveries,but that will be impossible if the amphibians disappear.The most serious aspect of amphibian loss,however,goes beyond the amphibians themselves.Scientists are beginning to think about what amphibian decline means for the planet as a whole.If the earth is becoming unlivable for amphibians,is it also becoming unlivable for other kinds of animals and human beings as well?Scientists now believe that amphibian decline is due to several environmental factors. One of these factors is the destruction of habitat,the natural area where an animal lives. Amphibians are very sensitive to changes in their habitat.If they cannot find the right conditions,they will not lay their eggs一These days,as wild areas are covered with houses,roads,farms,or factories,many kinds of amphibians are no longer laying eggs. For example,the arroyo toad（蟾蜍）of southern California will only lay its eggs on the sandy bottom of a slow-moving stream.There are very few streams left in southern California,and those streams are often muddy because of building projects. Not surprisingily,the arrovo toad is now in danaer of extinction.There are a number of other factors in amphibian decline.Pollution is one of them.In many industrial areas,air pollution has poisoned the rain,which then falls on ponds and kills the frogs and toads that live there,In farming areas,the heavy use of chemicals oncrops has also killed off arrtphibians.Another factor is that air pollution has led to increasedlevels of ultraviolet (UV) light. This endangers amphibians, which seem to be especiallysensitive to UV light. And finally, scientists have discovered a new disease that seems tobe killing many species of arnpttibians in different parts of the world.All these reasons for the disappearance of amphibians are also good reasons for moregeneral concern. The destrriction of land, the pollcition of the air and the water, thechanges in our atmosphere, the spread of diseases-these factors affect human beings,too. Amphibians are especially sensitive to environmental change. Perhaps they are likethe canary （金丝雀）bird that coal miners once used to take down into the mines to detectpoisonous gases. When the canary became ill or died,the miners knew that dangerous gases were near and their own lives were in danger.Scientists think that the decline of amphibians couldA:cause environmental change.B:cause a decline in other kinds of animals.C:be a warning signal for human beings.D:be a good sign for human beings.

共用题干Teaching Math,Teaching AnxietyIn a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship be-tween what female teachers think and what female students learn:If a female teacher is un-comfortable with her own math skills,then her female students are more likely to believe that boys are better than girls at math.If these girls keep getting math-anxious female teachers in later grades,it may create a snowball effect on their math achievement said Levine. In other words,girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up be-lieving that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident.Just as students find certain subjects to be difficult,teachers can find certain subjects to be difficult to learn一and teach.

Online distance learning is an instructional system which connects learners with educational resources．Students work on their own at home,at work,or at school and communicate with faculty and other students by means of e-mail,electronic meetings,videoconferencing,chat rooms,instant messaging and other forms of computer-based communication．There are both advantages and disadvantages to online distance learning.There are many benefits to using online distance learning environments．Online education is available all the time,anywhere and to all people．However,there are weaknesses for some learners．The online learner only has the written text and no other face-to-face hints．This may confuse the learner and cause misunderstanding．While distance learning allows for an openness,it is also difficult because it is done by e-mail messages and writing,and therefore may take more time than face-to-face learning．Sometimes the messages can be overwhelming for many online students.Universities,colleges and schools use online distance learning environments．These are important for students who may be unable to attend classes for various reasons like illnesses or busy everyday schedules．Some learners just want to further their studies at home．They enjoy the convenience of home learning as they take regular programs or enrichment classes.Online courses keep learners very occupied at all hours of the day．There are a great many messages and other online resources to read and respond to．Most learners have regular jobs or attend regular school classes on ground as well．However,the benefits are clear．Online distance learning is becoming very popular．Some online classes have become a profitable business as they replace regular traditional means of learning.Which of the following is TRUE of the passage about online distance learning?A.It has more disadvantages than advantageB.It is a learning form based on interneC.It is not available for some studentD.It has only enrichment classe
共用题干Learning Disorder一DyslexiaAs many as 20% of all children in the United States suffer from some form of the learning disordercalled dyslexia.Experts on dyslexia say that the problem is not a disease.They say that persons with dyslexia use infor-ination in a di价rent way.One of the worlds great thinkers and scientists Albert Einstein was dyslexic.Ein-stein said that he never thought in words the way that most people do.He said that he thought in pictures in-stead.The American inventor Thomas Edisoii was also dyslexic.Dyslexia first was recognized in Europe andthe United States more than 80 years ago.Many years passed before doctors discovered that persons with thedisorder were not mentally slow or disabled.The doctors found that the brains of persons with dyslexia aredifferent,In most people,the left side of the brain一the part that controls language一is larger than the rightside.In persons with dyslexia,the right side of the brain is bigger. Doctors are not sure what causes thisdifference.However,research has shown that dyslexia is more common in males than in females,and it isfound more often in persons who are left-handed.No one knows the cause of dyslexia,but some scientistsbelieve that it may result from chemical changes in a babys body long before it is born.They are trying tofind ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teachinghelp.After they have solved their problems with language,they often show themselves to be especially intelligentor creative.Many great thinkers and scientists in the world are dyslexic.A:RightB:WrongC:Not mentioned
