Ⅲ.阅读理解 All around the world, more and more people are donating their time to take part in online volunteering projects. What motivates them to help strangers without expectation of money or even thanks? Radha Taralekar helped teach Imelda how to protect herself from HIV, though the two have never met, and neither knows the other's name. From her home in Mumbai, the young woman took several weeks to write a guide especially for Imelda — who lost her children to HIV/Aids in Uganda. Taralekar received no payment for the job. Taralekar is one of a number of talented people who regularly donate their time online. But what is driving them to help total strangers, while asking for nothing in return? For Taralekar, the project gave her the chance to use her professional experience. “I want to serve people with my medical knowledge，” she says. For some, the inspiration to volunteer online was far more personal. After losing his wife to cancer, Tony Selman spent many hours online helping Cancer Research to collect data on the disease. “Seeing how painful she was when my wife was dying, I determined to help scientists find a cure for cancer，” he says. Interests and hobbies are also one of the factors. In 2011 Sam Luk, a designer, joined other online volunteers to try to help the police solve a murder case. Twelve years earlier the body of Ricky McCormick had been found killed in a field in St Louis, Missouri — the only clues being two encoded(译成密码)letters found in his pockets. Unable to decipher(破译)the codes, the police posted them online, calling for volunteers to help them make sense of the messages. “I'm interested in patterns and I love Sherlock Holmes，” says Luk. He spent hours every week trying to decrypt the notes, but the case remains unsolved to this day. For writer Clay Shirky, some large online volunteering projects benefit millions of people, giving him a sense of achievement and generosity. He helps write Wikipedia, the world's biggest encyclopaedia(网上百科全书), which is written entirely by people willing to donate their professional knowledge without any reward. 1. Which of the following is the best title? A. What caused Taralekar to help Imelda? B. What motivates people to help others? C. Why do people help strangers online? D. Where can we find volunteers online? 2. We can infer that Radha Taralekar is a ______. A. designer B. doctor C. writer D. policewoman 3. Sam Luk volunteered to help the police out of ______. A. interests and hobbies B. his duty of work C. money rewards D. a sense of achievement 4. When was Ricky McCormick found killed in a field in St Louis, Missouri? A. In 1999. B. In 2008. C. In 2011. D. In 2012. 5. Which of the following shows the structure of the passage? CP: Central Point　P: Point　SP: Sub­point(次要点)　C: Conclusion Ⅳ.阅读填空(每空不超过三个单词) Identity theft(身份盗用) is one of the fastest­growing crimes. Identity theft is a crime in which your personal information is stolen by someone and is used in an illegal way. When your identity is stolen, the thief often does fraud(诈骗)with that. He may get a credit card in your name and spend it carelessly without paying the bills; he may get a driver's license in your name and you have to be responsible for the accidents he causes… The popularity of the Inter and puters provides a gateway for the identity theft. The wealth of personal details people post on social works such as Facebook also makes it easier for identity thieves to obtain personal information. Many people are not aware of the problems caused by this crime. They wake up from their carefree attitude only when they bee a victim and suffer the damages caused by this crime. There is no cure for identity theft except prevention and this is why it is important that every person should bee cautious when using the Inter. The following tips may prevent you from identity theft. First, make sure your puter has an updated anti­virus and firewall system installed. Second, only enter your credit card details on secure sites, or websites that you've used before. Third, avoid giving away too much personal information on social working sites. Your date of birth, names of schools attended, phone number or the names of your parents are often required to verify an identity, and thieves can use this information too. Fourth, avoid sharing files as this gives other people access to your hard drive. Fifth, never open suspicious e­mails from unknown source. Last but not least, create plex passwords using a bination of numbers and keyboard symbols and change your passwords on a regular basis. Title: 1.__________ — one of fastest­growing crimes Ⅰ.

Ⅲ.阅读理解 Two organizations have announced plans to send people to Mars within the next 10 years. The Inspiration Mars Foundation, an American­based nonprofit organization, intends to send two people — probably a married couple — on a 501­day mission that will fly around Mars and return to Earth. They hope to launch in 2018. Mars One, a Dutch private pany, wants to land a team of four people on Mars by 2023. These people will settle on Mars forever. Mars is the most Earth­like pla we know, but it still is a very different world. Surviving on Mars will not be easy. Mars is a frozen desert, with no liquid water on its surface and a climate that makes Antarctica look fortable. Mars' atmosphere is thinner than that of Earth. The little air there is mainly made up of carbon dioxide which is unfit to breathe. Strong radiation(辐射) from the sun and other stars reaches the surface and would ruin their health if residents didn't wear spacesuits in the open air. Is there life on Mars? Not on the surface, most likely. Conditions are too harsh there. But microbial(微生物的)life might exist deep underground. Or maybe there are other forms of life, new to the earth. We just don't know. That's one of the reasons for going there. Ever since humans came into being on Earth, humans have always been explorers, seeking new lands and new opportunities. Now we're reaching farther than ever before. Human societies exist everywhere on Earth, even in frozen Antarctica. We have explored the deepest oceans and the highest mountains. At this moment there are half a dozen humans living aboard the International Space Station, orbiting the Earth a few hundred miles overhead. Is Mars the next human exploration destination? What will we gain from going to Mars? There's no gold or silver there. No oil. No natural resources worth mentioning. But it is the humans' curiosity that urges humans to explore the unknown world. New knowledge is something to treasure, for from new knowledge eventually e new abilities, and new understanding of the way the universe works. Would you go to Mars, given the chance? Why not? 1. Which of the following is true of the plan of Mars One? A. They will send two married couples to Mars. B. The four people will return to Earth in 2023. C. The four people will never return to the earth. D. It will take 501 days for the four people to reach Mars. 2. What is the main idea of the third paragraph? A. Surviving on Mars will be very difficult. B. Mars is the most Earth­like pla. C. Mars is a frozen desert with no water. D. Sending people to Mars is no easy job.　　3. What do you know about the climate of Mars? A. Mars is very hot. B. Mars is very mild. C. Mars is very cool. D. Mars is very cold. 4. We can infer that future residents on Mars ______. A. have to wear spacesuits outdoors B. don't have to wear spacesuits C. can breathe the air freely on Mars D. can get water from Mars' surface 5. At present, how many astronauts are living aboard the International Space Station? A. Four. B. Six. C. Eight. D. Twelve. Ⅳ.阅读填空(每空不超过三个单词) After experiencing heavy casualties(伤亡)and damage in powerful earthquakes since 2008, China is developing a way to give at least a few extra seconds' warning for those near quake epicenters(震中)． The system, called the National Earthquake Early Warning System, which will cost about 2 billion yuan, is expected to be built before 2017. The system mainly includes the construction of more than 5,000 quake­monitoring stations across the country. The system works by detecting earthquake­related shakings in the form of P­waves. P­waves move rapidly but are harmless, and they arrive before the more powerful and destructive S­waves. S­waves travel more slowly. So detecting P­waves with the system can provide a few precious seconds for people to escape before the more powerful S­waves arrive. The system is designed to rapidly detect the initiation of an earthquake, and it can determine how big the earthquake is and where it is located. The system can also issue a warning to people immediately through TV, short messages and emails. If quake­monitoring stations are about 30 km apart, the system can issue warning information about 10 seconds after a quake happens below ground. As earthquakes cannot be predicted, getting people to safety quickly before the destructive S­waves arrive can decrease casualties and reduce damage. Experts estimate that casualties could be reduced by 14 percent with a three­second advance warning of an earthquake, and 39 percent with a 10­second warning. And the few seconds of warning can also help a train driver slow down to avoid possible derailment, and give a shutdown signal to chemical factories or nuclear plants to prevent potential leaks and fires. But the system has its limitations. The S­waves generally move at a speed of 3.5 km per second, which means before the warning is issued, S­waves have already spread in a radius(半径)of 35 km from the epicenter. The area within the 35­km radius of the epicenter called the “blind area” cannot be warned. The system cannot play a role in *** all quakes, either. Unit 3 Ⅰ.1.

10[KHC2O4·H2C2O4]＋8KMnO4＋17H2SO4＝8MnSO4＋9K2SO4＋40CO2↑＋32H2O

设KHC2O4·H2C2O4·2H2O的量为 A 摩尔。那么，所消耗的NaOH 摩尔数 = 3A 摩尔。若所用的NaOH 体积为 X L, 就有: 3A = 0.1000 (mol·L－1) x X (L),即，A = 0.1000X /3 摩尔

又，氧化 A 摩尔的KHC2O4·H2C2O4·2H2O，需消耗KMnO4的量=4A/5 = 4x0.1000X/15 摩尔 ，已知消耗KMnO4溶液的体积=X/3 L.
所以，KMnO4溶液的浓度（mol·L－1）= （4x0.1000X/15 摩尔）/（X/3 L）
=0。08000 mol/L
