Many do-it-yourself homeowners are interested in
trying out solar power to leam about the technology and
perhaps to provide energy for limited-use applications．
There are a variety of ways to find cheap solar panels
（板）, including buying used and building your own
with factory seconds．Both methods will save money
while forcing you to learn the ins-and-outs of a solar
power array （陣列）．  
We've all seen solar-powered street signs or PV
panels being used for various purposes at remote locations．
When those units become cracked or chipped and are considered "unsafe", companies are forced to replace them, generally to avoid responsibility issues．Because it's difficult to get rid of PV panels, many companies, if approached, are willing to give them away or to sell them for modest prices．Depending on the degree of damage present, expect to see performance degradation （降級(jí)） in the range of 10% to 60%．A multimeter （萬用表） can be used to test the panel before buying．If the panel's free, take it anyway．It could still be useful in a home solar project．
A solar panel is really nothing but a box serving as a container for a large group of solar cells．Factory second solar cells are usually sold on eBay at a small part of their regular cost．The cells come in a variety of sizes．You will need to figure out how much power a single cell produces to determine how many will need to be wired together to form an array．
A simple search of the Internet will show numerous sites detailing home solar panel projects．Do-it-yourself lovers are generally quite generous in supply photographs of their work and description of what went wrong and right with the project．
Getting cheap solar panels with slight imperfections, either used or through sales of factory seconds, is a perfect solution for home-built renewable energy projects．The high number of solar lovers online provide a wealth of useful information．Only limited skills are required, plus an understanding of the basic wiring involved．All are well within the talents of almost any home handyman．Beyond the satisfaction of having completed the project, you'll come away with a functional solar panel that will be a source of power for use around the house or at remote locations．
Solar energy systems are quickly becoming more popular with homeowners as prices continue to decline．
72．The author writes the passage to introduce ____．
A．ways of finding cheap solar panels B．ways of saving energy
C．a(chǎn) way of making a solar panel     D．a(chǎn) home-built energy system
73．What does the phrase "factory seconds" in the passage refer to?
A．Second-hand factory products．  B．Cheap but perfect factory products
C．Faulty factory solar cells．        D．The second best factory solar cells
74．From Paragraph 5, we can learn about home-built energy projects that ____．
A．none of them are beyond home handymen
B．a(chǎn) lot of useful information is available on the Internet
C．a(chǎn) perfect solution is to get cheap and perfect solar panels
D．understanding electrical wiring is not necessarily needed
75．What is the author's attitude towards the future of solar energy systems?

D
What is a good education? The question is far from being answered. Once more, colleges and universities are changing their programs: they drop "fun courses" and restart some of the traditional subjects neglected (忽視) since the 1960s. Many great schools are again requiring the students to take a number of classes in English, history, literature, the social sciences, philosophy, the natural sciences, and art if they want to get a degree. Meanwhile, the experts are trying to describe the good education of our time. Obviously the purely vocational training once favored is not enough. But neither is the gentleman's education of the nineteenth century. Educational programs must meet the demands of a modern world where men and women have to work and to deal with big problems.
What, then, is a good education of this century? Some educators suggest that it should include foreign languages and the study of foreign cultures; a mastery of English, including the ability to write and speak well, because communications have become all-important in the modern world, and also because "a person who doesn't speak and write clearly doesn't reason clearly either"; some knowledge of the social sciences (sociology, psychology) that deal with human relations and human problems; some basic knowledge of modern science, which would enable future voters to be better informed about current problems like nuclear. Finally, many educators insist that all college graduates should be familiar with computers and modern information system since the educated professionals of tomorrow will have to understand their machines. Is that all? "No, of course not." answer the educators. "We have not mentioned the two great building blocks of education: history and literature!"
71．The best title for this passage might be _______.            
A．Education           B．A Mastery of English
C．A Good Education   D．Something About Study
72．The underlined word "drop" in the first paragraph means _______.
A．desert       B．dislike      C．decline     D．neglect
73．The author thinks that the question about what a good education is _______. 
A．has been answered fairly well                     
B．hasn't been put forward yet
C．has been dealt with successfully                   
D．has not been answered satisfactorily
74．Some educational experts believe a mastery of English should include the ability _______.
A．to read fast                        B．to write and speak well
C．to write clearly and accurately    D．to listen and speak skillfully         
75．Which of the following statements is not mentioned in the passage?      
A．Educational programs must meet the demand of a modern world.
B．The students will not get a degree unless they take a number of classes in English, history,
literature, the social sciences, philosophy, the natural sciences and art.
C．A good education should include foreign language and the study of foreign culture.
D．Every student ought to take part in military training.

The questions of what children learn, and how they should learn it, is continually being debated and reheated. Nobody dares any longer to defend the old system, the parrot – fashion (way of learning by repeating what others say) of learning lessons, the grammar with a whip system，which was good enough for our grandparents．The theories of modern psychology have stepped into argue that we must understand the needs of children．Children are not just small adults；they are children who must be respected as such．
Well，you may say，this is as it should be，and a good idea．But think further．What happens?
‘Education’ becomes the responsibility not of teachers, but of psychologists．What happens then? Teachers worry too much about the psychological implications of their lessons，and forget about the subjects themselves．If a child dislikes a lesson，the teacher feels that it is his fault，not the child’s. So teachers worry whether history is ‘relevant’ to modem young children．And do they dare to recount stories about violent battles? Or will this make the children themselves violent? Can they tell their classes about children of different races，or will this encourage racial hatred? Why teach children to write grammatical sentences? Verbal expression is better．Sums? Arithmetic? No：real—life mathematical situations are more understandable．
You see．you can go too far．Influenced by educational theorists，who have nothing better to do than write books about their ideas，teachers leave their teacher—training colleges filled with grand，psychological ideas about children and their needs. They make complicated preparations and try out their ‘modern methods’ on the long – suffering children. Since one ‘modern method’ rapidly replaces another, the poor kids will have well been fed up by the time they leave school. frequently the modern methods are so complicated that they fail to be understood by the teachers, let alone the children; even more often, the relaxed discipline so necessary for the ‘informal’ feeling the class must have, prevents all but a handful of children from learning anything.
63．Under the old system, children were           .
A．made to learn passively                        B．good enough to their grandparents
C．made to learn actively                          D．understood and respected by teachers
64．What happens when teachers pay too much attention to the psychological implications during a lesson?
A．They find that children dislike the lessons.
B．They worry too much about history, stories, racial hatred, grammar and arithmetic.
C．They don’t pay enough attention to what students are learning.
D．They tend to blame students for their failure in teaching.
65．How do you understand the underlined sentence at the end of the passage?
A．Children will learn well in a relaxed classroom atmosphere.
B．Few children will actually learn when there is no discipline.
C．Relaxed discipline is necessary for children to develop.
D．No children will learn anything without strict discipline.
66．What is the author’s attitude toward the theories of modern psychology?
A．Indifferent (不關(guān)心的).                       B．Tolerant (容忍的).
C．Supportive (支持的).                           D．Critical (批評(píng)的).

（B）
People have wondered for a long time how their personalities and behaviors are formed．It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive．
Social scientists are, of course, extremely interested in these types of questions．They want to explain why we possess certain characteristics and exhibit certain behaviors．There are no clear answers yet, but two distinct schools of thought on the matter have developed．As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory．The controversy is often referred to as “nature/nurture”．
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors．That our environment has little, if anything, to do with our abilities, characteristics, and behavior is central to this theory．Taken to an extreme, this theory maintains that our behavior is predetermined to such a degree that we are almost completely governed by our instincts．
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claimed that our environment is more important than our biologically based instincts in determining how we will act．A behaviorist, B．F．Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings．The behaviorists’ view of the human being is quite mechanistic; they maintain that, like machines, humans’ respond to environmental stimuli as the basis of their behavior．
Either of these theories cannot yet fully explain human behavior．In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes．That the controversy will continue for a long time is certain．
69．Which of the following statements would the supporters of the “nature” theory agree with?
A．A person’s instincts have little effect on his actions．
B．Environment is important in determining a person’s behavior and personality．
C．Biological reasons have a strong influence on how we act．
D．The behaviorists’ view correctly explains how we act．
70．Concerning the nature/nurture controversy, the writer of this article____________．
A．supports the nature theory
B．supports the nurture theory
C．believes both are completely wrong
D．thinks that the correct explanation of human behavior will take ideas from both theories．
71．In the United States, Black people often score below White people on intelligence tests．With this in mind, which of the following statements is NOT true?
A．Nature proponents would say that Whites are genetically superior to Blacks．
B．Supporters of the nature theory would say that Whites score well because they have a superior environment．
C．Behaviorists would say that Blacks often lack the educational and environmental advantages that Whites enjoy．
D．Nurture proponents would disagree that Blacks are biologically inferior to Whites．

D
The eruption of a volcano in the Canary Islands could trigger a “mega-tsunami”（巨大海嘯）that would hit Atlantic coastlines with waves as high as 330 feet, scientists said on Wednesday. They said an eruption of the Cumbre Vieja volcano on La Palma, part of the Spanish island chain off West Africa, was likely to cause a massive chunk（大塊）of rock to break off, crashing into the sea and kicking up huge walls of water higher than any other in recorded history. The tsunami would be capable of traveling huge distances at up to 500 miles an hour, the scientists said in a research paper to be published soon.
Simon Day, of the Benfield Greig Hazard Research Centre at the University College of London, said that as the volcano was not erupting at present, the short-term and medium-term risks were “negligible”. But Cumbre Vieja should be monitored closely for any signs of activity so that emergency services could plan an effective response, he said. “Eruptions of Cumbre Vieja occur at intervals of decades to a century or so and there may be a number of eruptions before its collapse（倒塌）,” said Day, who cooperated on the research with Steven Ward of the University of California. “Although the year-to-year probability of a collapse is therefore low, the resulting tsunami would be a major disaster with indirect effects around the world.”
The effects would spread north, west and south of the Canaries, with the west Sahara bearing the worst of the wave’s energy. The energy released by the collapse would be equal to the electricity consumption of the entire United States in half a year.
Immediately after the landslide（山崩）,a huge wave of water 93,000 feet high and tens of miles wide would form. As the landslide rocks moved deeper under water, a tsunami would develop. Within 10 minutes, the tsunami would have moved a distance of almost 155 miles. On the west Saharan shore, waves would probably reach heights of 330 feet.
Florida and the Caribbean, the final north Atlantic destinations to be affected by the tsunami, would have to brace themselves for 165-foot waves some eight to nine hours after the landslide. Wave heights toward Europe would be smaller, but substantial waves would hit the coasts of Britain, Spain Portugal and France. The research paper estimated water would penetrate several miles inland and that the devastation would cause trillions of dollars in damage.
76. What would be the result of a big chunk rock falling into the sea?
A. Waves would be very high.                                         B. The volcano would stop.
C. Walls of water would kick up a storm.                          D. An earthquake would take place.
77. The word “negligible”(Line 3, Paragraph 2) is closest in meaning to ______.
A. unimportant                    B. small                              C. predictable               D. avoidable
78. From the passage we may learn that the volcano erupts ______.
A. every year                                                                 B. every 5 to 9 years
C. every 10 to 100 years                                                        D. every 5 to 10 months
79. All of the following are true EXCEPT ______.
A future eruption of Cumbre Vieja volcano may experience a massive collapse
Waves generated by the landslide could even reach the coasts of the United States
The landslide-released energy is equal to half a year’s electricity consumption in the US
American scientists have managed to utilize the volcanic energy for civil purposes

C.
Here are two letters from our readers expressing their concern about school assessment (評(píng)價(jià)):
(l)
Students should be allowed to study without worrying about grades (學(xué)習(xí)成績(jī)). Fortunately, most educators realize that students have different interests and abilities. However, grade-based assessment is still very common. Grades often hold back creativity. Competing for better grades causes many students to turn down opportunities to go in for music, drama and sports. Grades are also an unfair measure of a student’s ability. I do not demand, as some extremists do, that grades should no longer be recorded. However, I do believe that less importance should be placed on. grades. I hope that someday grades will become optional(可選擇的) at Village High School.
Magdalena Smith, President
Drama Club
(2)
Let’s face the facts about grades. Grades perform three basic functions( 功能). First, grades get students to work at their highest level of competence  (能力 ). Second, they act as an encouragement for hard-working students and as a warming to those who are not. Finally, grades are an effective standard by which to measure students' achievement. Good grades help students to get jobs and to get into university.
I've spoken with a number of students who have jobs, and most of them say that they were hired mainly because of their grades. My grades helped me get a part-time job and will help me into university next year. I think grades are extremely important at Village High School.
Simon Harper, Member,
Science Club
64. Simon Harper writes from the viewpoint of someone who      
A. insists grades should become optional in the near future
B. believe in the advantages of assessment based on grades
C. is concerned about improving students' creativity
D. supports using students' interests to measure their abilities
65. Magdalena Smith thinks it is important for       .
A. educators to assess the students by grades
B. educators to pay more attention to grades
C. students to compete for better grades
D. students to take part in music, drama, and sports
66. According to the letters, which of the following is TRUE about Village High School?
A. Grades are effective in every way.    
B. Grades hold back students' creativity. .
C. Grades bring about unnecessary worries.
D. Grades are still in use at present.    .
67. What are the two letters mainly about?
A. The role that grades should play in assessing students.
B. The importance of art and music in students' life.
C. The need to have a standard measure for students' success.
D. The reasons why grades shouldn't be used to assess students.

Among the most popular books being written today are science fictions (小說). Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories.
It is often thought that science fiction is a fairly new development in literature, but its forefathers can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a main subject which is still often found in modern stories.
Most of the classics of science fiction, however, have been written within the last one hundred years. Books by writers, such as Jules Verne and H.G. Wells, to mention just two well–known authors, have been translated into many languages.
In an age where science fact frequently overtakes (超過) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are clear-sighted to see how the ways are going, however, may provide a valuable lesson on how to deal with the problems which society will unpreventably face as it tries to master its new technology and come to terms with a continually changing view of the world.
45. It can be concluded that modern science fiction ______
A. is worse than that in the past
B. shows the writer’s viewpoints
C. tells stories about men from other planets
D. has been written only by Jules Verne and H.G. Wells
46. From the article we get the impression that science fiction ______.
A. is popular
B. is a fairly new development in literature
C. reflects the technical advances in the past
D. describes things that happen in developed countries
47. Which of the following statements is true?
A. Science fiction is based on successful films.
B. Science fiction often overtakes science fact.
C. Writers may find it easy to keep ahead of scientific advances.
D. The writer who can see clearly the way we are going will give us valuable instructions.

Can you train your cat to actually use your toilet? Can you not have to deal with litter boxes any more? Well for many people the answers to these questions are yes．
You may have heard that some people have managed to train their cats to use the human toilet, Well this is correct．One advantage to this is the fact that you no longer have to lug heavy bags of litter home from the supermarket, or worry about cleaning out the dirty litter everyday．
Like any other cat training program, training your cat to use the toilet takes times and patience, you just can put your cat on the toilet and hope that they can use it．
By slowly shaping your cat’s behavior over a couple of weeks, you too can end lugging heavy bags of cat litter home from the supermarket．First, start by slowly moving the litter box closer and closer to the toilet each day, so your cat gets used to being in the bathroom and being around the toilet．
Next, when you have had to litter box next to the toilet for several days, slowly raise the litter box higher and higher each day until it is at the level of the toilet．Then find an insert for the top of the toilet, like a shallow pan that can sit in the rim of the toilet and hold litter．
Once your cat gets used to using this litter pan on top of the toilet for a week or so, try removing the pan and your cat should be able to use the toilet．
Like any cat training program, it takes time and effort on the part of the cat owner to do this．Don’t get frustrated with your cat if she is not learning as fast as you would like, many cats learn at their own pace．With a little effort you too can have a toilet trained cat．
64．The author advises you to train your cat to use a toilet so that may    ．
A．keep the toilet clean
B．keep the cat clean
C．save a lot of trouble
D．save a lot of money
