Hi Cindy,
Please don"t worry if you feel a little strange around boys．You are in the process of 36 from a little girl into a young woman and there are 37 called hormones （荷尔蒙） that are changing not only your body but your 38 ．For example, you say you used to feel at ease _39_ boys and you would usually run and fight one another for 40 ．That was Cindy, the little girl．Cindy the 41 woman doesn"t want to fight boys or even run with them 42 your interests are changing．That is what is making you feel strange and it is also 43 to the other girls around you and also to the boys．Your life is 44 a different stage but you should understand that this is （a） 45 normal, and （b） something that will pass quickly．
I think you should again try to 46 around boys．You can still talk with them about 47 you like including sports, movies, web sites and celebrities（名人）．I 48 that you not try to fight with them, however, because the 49 are becoming much bigger and stronger．I think you will find that you will _50_ being with boys but that your feelings will be different from the 51 they used to be．I know you are not supposed to have a 52 while you are still in school in China, but if you start to find some boys very handsome and you are strongly __53_ to some of them, don"t be surprised． 54 , this is all very normal．For now, you should _55_ your school work, though you will find that some boys are attracted to you．This will be a new adventure for you and my best advice is to relax and enjoy it．
Good luck,
Brad

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 （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

War, money and power are a few things that countries and people are concerned about. 36 I agree that those things are important，I believe that everyone should start to 37 more on a growing problem — global warming.
Global warming will not only 38 our country and our generation, but a1so the entire 39 and future generations. It is 40 because the weather has been a lot warmer over the past few years, which 41 the melting（融化） of the ice in the Antarctic. This will soon cause water levels to 42 and flood parts of the world.
Many people ignore this problem because they fee1 43 they can’t do anything about it and have more 44 things to worry about. If we al1 45 so，then our ozone layer（臭氧层）will be 46 and the planet will no longer be able to make life continue to exist. We should do our best to limit the use of our planet’s 47 resources（资源）and keep our air clean. 48 , future generations will suffer from our 49 .
Some might feel that they can"t stop global warming from 50 But if every single person does his or her part in keeping the air clean. then it will become a 51 effort. Sure, there are some things that cause pollution and that we won’t be able lo 52 change. This may include cars burning oil，but we can 53 adjust some of these things. People can start carpooling, taking the bus, riding their bikes, or . 54 just walking.
If everyone takes 55 now, I believe we can start seeing remarkable results within a few years.

Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well. Today, about 160 million people depend on the Nile River for their living. Within the next 25 yeas ,the district"s population is expected to double, adding to the demand brought about by growth in industry and agriculture. The frequent drought（干旱）adds to the urgency.
Water quality is also a problem. Precious soil is washed out to sea. Wastes from industry and agriculture create pollution. Higher concentrations of salt influence irrigated soils. Water-borne diseases continue unchecked. In areas where it"s hot and damp, water hyacinths choke off lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day. They’ve seen the river change course, and their only source（来源） of water thickened with mud. They’re very poor and have few choices.
But a new program, the Nile Basin Initiative （NBI），is offering very practical assistance. The program is more than just a water-management project. It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions（解决办法）. Half the Nile Basin"s countries are among the world"s poorest nations；yet, somehow, they must find the resources, skills and political will to overcome these challenges.
68. What are the great challenges the Nile Basin faces？
A. The development of .shipping industry.
B. Overfishing of native people.
C. Water shortage and water quality.
D. Increasing population and tourism.
69. The underlined word “hyacinths”（in Paragraph 3） refer to “ ”.
A. animals B. plants C. rocks D. salts
70. The program NBI is mainly aimed at .
A. preventing water pollution B. changing the river course
C. improving living condition of the poor
D. preventing land from becoming desert
71. What would be the best title of this passage？
A. People"s Life in Egypt and Sudan
B. Frequent Drought in Egypt and Sudan
C. The Poorest Countries in the Nile Basin
D. The Ecosystem Problems in the Nile Basin

The announcements by the NASA，in the form of several Web site postings and a video posted on YouTube，were in response to worries that the world will end on Dec．21，2012．
The doomsday(末日) rumour reached a high point with the release of the new movie “2012”，directed by Roland Emmerich．In th
e movie，Yellowstone blows up, showering the continent with black ash．Tidal waves wash over the Himalayas，where the governments of the planet have secretly built a ship which a select 400，000 people can ride out the storm．There are hundreds of hooks devoted to 2012，and millions of Web sites，depending on what combination of“2012”and“doomsday”you type into Google．All of it，astronomers say, is nonsense．“Most of what"s claimed for 2012 relies on wishful thinking and ignorance of astronomy．”Ed Krupp， an expert on ancient astronomy，wrote in an article in the November issue of Sky＆Telescope．“I get angry at the way people are being influenced and frightened to make money,” Morrison said．“There is no right to frighten children to make a buck．”suggested David Morrison，an astronomer at the NASA Ames Research Center in Moffett Field，Calif．He said he had been getting about 20 letters and e—mail messages a day from people as far away as India scared out of their wits．Morrison said he did n
ot blame the movie for all this，as much as many other supporters of the Mayan prediction．But then，he said，“my doctorate is in astronomy，not psychology．”In an e—mail exchange, Krupp said：“We are always uncertain about the future，and we always consume representations of it．We are always attracted by the romance of the ancient past．”A NASA spokesman，D
wayne Brown，said the agency did not comment on movies，leaving that to movie critics．But when it comes to science, Brown said, “we felt it was careful to provide a resource．” If you want to worry，most scientists say，you should think about global climate change or nuclear war．But if ancient prophecies(预言)get you going，here are some things Morrison and the others think you should know．
64．Which of the following statements is TRUE according to the passage?
A．Dr．Morrison blamed the Movie“2011”for the panic it aroused in the public around the world．
B．People who watched the movie were seared and firmly believed that the end of the world was coming．
C．In terms of science it was better to provide evidence and theory at the same time．
D．Dr．Morrison thought it was not right to make money by frightening people．
65．It can be inferred from the text that
．A．astronomers think that doomsday is likely to happen in the near future
B．the reason why the NASA posted web site postings was to make people interested in astronomy
C．scientists think we shouldn"t worry about doomsday but show concern about environment protection
D．most astronomers agree that the world is not ending—at least anytime soon
66．Which of the following would be the best title?
A．A New Movie“2012” B．Is Doomsday Coming?
C．End-of-the-World Stories D．Astronomers Comment on Movies
67．What would the author probably discuss in the paragraph that follows?
A．Evidence that the Mayans thought something special would happen in 2012．
B．What will really happen in 2012．
C．The reason why there is no need to worry about doomsday．
D．Ancient stories about the end of the world．

Backpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don’t mind carrying a heavy load, your backpack might also power your MP3 player, keep your cell phone running, and maybe even light your way home.
Scientists from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass., have invented a backpack that makes electricity from energy produced while its wearer walks.
The backpack’s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer’s back, and the whole pack moves up and down as the person walks. A mechanism with gears(传动装置) collects energy from this motion and transfers it to an electrical generator.
Surprisingly, the researchers found, people walk differently when they wear the springy packs. As a result, wearers use less energy than when carrying regular backpacks. Also, the way the new packs ride on wearers’ backs makes them more comfortable than standard packs.
The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. These people often rely on global positioning system(GPS) receivers, night-vision goggles(夜视镜), and other battery-powered devices to get around and do their work. Because the pack can make its own electricity, users don’t need to give up space in their packs to lots of extra batteries.
For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren’t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!
65. The passage introduces a new kind of ______ backpack.
| A．electronic | B．electricity-producing |
| C．electron-generating | D．electricity-controlling |
batteries placed at the bottom of the frame
the motion of the pack while the wearer walks
energy the wearer consumes for carrying the pack
the collective motion of a mechanism and some gears
67. From the passage, we can infer that ______.
the backpacks of mountaineers may become smaller in the future
the new backpack can hardly be produced due to its potential danger
the new backpack will someday replace MP3 players and cell phones
the backpack will also provide electricity for lighting our houses
68. An enormous disadvantage of power-generating backpacks might be that ______.
they may stop working at any time
it takes quite a while to have the energy transferred
they may distract the wearer’s attention from road safety
they will be extremely heavy with the mechanism
