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 (阵列).
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 (降级) in the range of 10% to 60%.A multimeter (万用表) 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 way of making a solar panel D.a 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 lot of useful information is available on the Internet
C.a 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?
A.Optimistic. B.Pessimistic. C.Indifferent. D.Doubtful

Some fish form huge schools. Could fish set up schools and teach their children how to survive in the ocean? You may ask. No. Here the “schools” are not the places where you study. They are fish shoals (鱼群) that cover tens of kilometers. What causes hundreds of millions of fish to gather and move together is one of biology’s mysteries.
Darkness appears to be the first step to the creation of shoals, according to a study published in the March 27 journal Science. A team of researchers from the Massachusetts Institute of Technology (MIT) and five other institutions studied Atlantic herring (鲱鱼), which forms shoals on a fishing ground off Massachusetts. They used an underwater imaging technology and fish-finding sonar (声纳) to observe the herring over several days in autumn when they spawn (产卵).
They found that, as the sun set, fish in scattered (分散的) groups began swimming much closer to one another than they normally do. When the number of fish reached a certain point in an area, this set off a chain reaction of similar behavior that spread like a sound wave through the water.
The herring’s movement seemed to be started by sunset. The team didn’t record the breakup of these shoals, but a previous study suggested that as the sun rose, the shoals fell apart.
“When the light fades (逐渐消失), it’s safer for the fish to move away from the seabed,” says Nicholas Makris, a professor at MIT who led the research. “Once they have a certain number of other fish, they suddenly come together - forming a shoal covering tens of kilometers within tens of minutes.”
Herring form shoals to migrate during the autumn spawning season. Some shoals were 40 km across and 30 m from top to bottom. They formed in deep water and moved into more shallow waters to spawn.
Forming shoals helps protect them from predators (掠食者) by giving them simple strength in numbers. The ordered movement of the shoal means the fish can reach their spawning ground more quickly and more safely.
Scientists have never before gathered information on so many animals acting together. Understanding these herring shoals could lead to more ideas about what causes animals to move in schools, says Iain Couzin, a biologist at Princeton University, US.
1. Which school in the following expressions is used the same way as the underlined one in the first paragraph?
A. schools of thoughts B. school a horse C. a school of whales D. a medical school
2. Which of the following statements is true?
A. There are more large shoals of herring at night than in the daytime.
B. The research on Atlantic herring was conducted independently by the Massachusetts Institute of Technology.
C. The larger the shoal of herring is, the more slowly it moves.
D. Scientists have found out the reason why fish gather and move together in huge shoals.
3. According to the research, herring tend to get together except ______.
A.when there are predators around B. when they spawn C. when the sun sets D. when the sun rises
4. What seems to be the main reason for herring to gather and move together?
A. To avoid the darkness.
B. To keep other kinds of fish out of their spawning ground.
C. To spawn in the shallow waters.
D. To make themselves feel safe.

TAIBEI-Increasing numbers of Taiwanese students are joining the island’s “China rush”, seeking education on the Chinese mainland.
According to official Chinese figures, the number of Taiwanese students admitted into college and postgraduate(研究生)programs on the mainland totaled 461 in 1996, 928 in 1997 and 839 in 1998.Although no latest official numbers were available,” Netbig. Com Said this number had risen between 30 to 50 percent annually in the past two years with well over 1000 entering mainland campuses last year.
The Internet site, based in the Chinese city of Shenzhen, provides education service and information on Chinese mainland college and universities. “Many Taiwanese believe a Chinese education giving more knowledge about the people and culture in the mainland will increase their chances in the Chinese job market, Net. Com vice-president Ingrid Huang said.“I believe it will give me hands-on experience in the business field in the Chinese mainland and a better understanding of the Chinese mainland people,” said Lydia Chang, a 19-year-old majoring in journalism at Shih Shin University. Chang plans to go on to get a master’s degree in business administration in Shanghai, which she says offers the best environment for such studies.
A journalism graduate student, surnamed Lin, at the National Taiwan University said he would like to study law on the Chinese mainland since “there will be better career prospects now that more Taiwanese companies are going there”. “They hope the children could build up connections which could later become useful in their business operations,” said Yang Ching-yao, professor of the Chinese mainland studies. A Netbig. Com survey showed the campuses favored by Taiwan students included Beijing, Qinghua and Renmin universities in Beijing, and Jinan and Zhongshan universities in Guangzhou. The most popular studies were law, business and Chinese medicine.
