Operation Always ride your bike in a safe, controlled manner on campus. Obey rules and regulations. Watch out for walkers and other bicyclists, and always use your lights in dark conditions.
Theft Prevention Always securely lock your bicycle to a bicycle rack—even if you are only away for a minute. Register your bike with the University Department of Public Safety. It’s fast, easy, and free. Registration permanently records your serial number, which is useful in the possible recovery of the bike stolen.
Equipment
Brakes Make sure that they are in good working order and adjusted properly.
Helmet A necessity, make sure your helmet meets current safety standards and fits properly.
Lights Always have a front headlight—visible at least 500 feet in front of the bike. A taillight is a good idea.
Rules of the Road
Riding on Campus As a bicycle rider, you have a responsibility to ride only on streets and posted bicycle paths. Riding on sidewalks or other walkways can lead to a fine. The speed limit for bicycles on campus is 15 mph, unless otherwise posted. Always give the right of way to walkers. If you are involved in an accident, you are required to offer appropriate aid, call the Department of Public Safety and remain at the scene until the officer lets you go.
Bicycle Parking
Only park in areas reserved for bikes. Trees, handrails, hallways, and sign posts are not for bicycle parking, and parking in such spots can result in a fine.
If Things Go Wrong
If you break the rules, you will be fined. Besides violating rules while riding bicycles on campus, you could be fined for:
×No bicycle registration…$25 ×Bicycle parking banned…$30
×Blocking path with bicycle…$40 ×Violation of bicycle equipment requirement…$35

Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.
According to Science Daily, a new study predicts that by the year 2100, many of today’s familiar climates will be replaced by climates unknown in today’s world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.
Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn’t matter what is causing it, but rather, what can be done about it. What’s more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.
However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data.
小题1: Which of the following would be the best title for the Passage ?
| A．Ways to protect our planet. | B．Solutions to climate change. |
| C．Be prepared for climate change. | D．Climate change and its effects. |
| A．To show the damage earthquakes caused. |
| B．To remind people to prevent future earthquakes. |
| C．To show major changes are taking place on the planet. |
| D．To tell us more earthquakes will happen in the future. |
| A．Separated. | B．Destroyed. | C．Removed. | D．Affected. |
| A．Animals and plants won’t die out as long as climate changes slowly. |
| B．There’s enough data for us to predict the future of climate change. |
| C．The world is getting more unstable because of animal migration. |
| D．The earth is not the only planet that is experiencing climate change. |
Merrigan, a former college professor, is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture. Aside from trying to stop the graying of America"s farmers, her work is made tougher by a recent blog posting that put agriculture at No.1 on a list of "useless" college degrees. Top federal agriculture officials are talking about the posting, and it has the attention of agricultural organizations across the country.
“There couldn"t be anything that"s more incorrect," Merrigan said. "We know that there aren"t enough qualified graduates to fill the jobs that are out there in American agriculture.
In addition, a growing world population that some experts predict will require 70% more food production by 2050, she said.
“I truly believe we"re at a golden age of agriculture. Global demand is at an all-time record high, and global supplies are at all-time record lows," said Matt Rush, director of the Texas Farm Bureau. "Production costs are going to be valuable enough that younger people are going to have the opportunity to be involved in agriculture”.
The Department of Agriculture has programs aimed at developing more farmers and at increasing interest in locally grown food. The National Young Farmers" Coalition has also been pushing for state and federal policy changes to make it easier for new fermers.
Ryan Best, president of Future Fanners of America, has been living out of a suitcase, traveling the country and visiting with high school students about careers in agriculture. The 21 -year-old Best hopes his message-that this is a new time in agriculture-will motivate the next generation to turn around the statistics.“Never before have we had the innovations (创新）in technology which have led to agriculture in this country being the most efficient it has ever been” he said. “There’s really a place for everybody to fit in”
小题1:What is the new challenge to American agriculture?
| A．Fewer and older farmers. | B．Higher fuel prices. |
| C．More natural disasters. | D．Lower agricultural output. |
| A．To draw federal agriculture officials" attention |
| B．To select qualified agriculture graduates. |
| C．To clarify a recent blog posting. |
| D．To talk more students into farming careers |
| A．the government will cover production costs |
| B．global food supplies will be even lower |
| C．investment in agriculture will be profitable |
| D．America will increase its food export |
| A．To re-analyze the result of the national census. |
| B．To increase production. |
| C．To bring down the average age of farmers. |
| D．To invest more in agriculture. |
| If blood is red, why are veins (静脉) blue? Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker（超级油轮）. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Why do teeth fall out, and why don’t they grow back in grown-ups? Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed（腐烂）and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off. Do old people shrink（收缩）as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy)? Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not. Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system（边缘系统）. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet. If exercise wears you out, how can it be good for you? Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease. |

| A．Because their spine is in active use. |
| B．Because they are more easily affected by gravity. |

The first real mobile telephone call was made in 1973 by Dr Martin Cooper, the scientist who invented the modem mobile handset． Within a decade, mobile phones became available to the public． The streets of modem cities began to feature sharp-suited characters shouting into giant plastic bricks． In Britain the mobile phone quickly became the same with the "yuppie" , the new type of young urban professionals who carried the expensive handsets as status symbols． Around this time many of us said that we would never own a mobile phone．
But in the mid-90s, something happened． Cheaper handsets and cheaper calling rates meant that, almost overnight, it seemed that everyone had a mobile phone． And the giant plastic bricks of the 80s had changed into smooth little objects that fitted nicely into pockets and bags．
Moreover, people" s timekeeping changed． Younger readers will be amazed to know that, not long ago, people made spoken arrangements to meet at a certain place at a certain time． But later Meeting times became approximate under the new order of communication: the Short Message Service （SMS） or text message． Going to be late? Send a text message! It takes much less effort than arriving on time, and it" s much less awkward than explaining your lateness face to face and the text message has changed the way we write in English． Traditional rules of grammar and spelling are much less important when you" re sitting on the bus, hurriedly typing "Will B 15mm late - C U @ the bar． Sorry! - ）"．
Alexander Graham Bell would be amazed if he could see how far the science of telephony has progressed in less than 150 years．If he were around today, he might say "That" s gr8! But I" m v busy rite now．Will call U 2nite．"
小题1:What does the underlined part in Para． 2 refer to?
| A．Houses of modern cities． | B．Sharp-suited characters． |
| C．New type of professionals． | D．Mobile phones． |
| A．People were more likely to be late for their meeting． |
| B．SMS made it easier to inform each other． |
| C．Young people don" t like unchanging things． |
| D．Traditional customs were dying out． |
| A．Call U@ SKUg8 2nite． | B．IM2BZ2CU 2nite． |
| C．CU@ the bar g8 2nite． | D．W84U@ SKUg8 2nite． |
| A．Alexander Graham" s invention． |
| B．SMS @ a new way of communication． |
| C．New functions of the mobile telephone． |
| D．The development of the mobile phone． |
When an ecosystem has not been pushed past certain limits, it is able to recover on its own. Human involvement should only play a minor role, including after an earthquake. This is particularly the case for sandy grasslands, grasslands deserts, the mountains of the south and the northern sides of mountains in the north. In these areas soil remains and the water, light, heat and nutrients needed are available. Less human involvement is even more appropriate in areas with a small population, where it can avoid money being wasted on ineffective efforts, such as creating forests in dry areas.
The creation of nature reserves should be a model to allow damaged ecosystems to recover. Funding can start at the national level; centrallyfunded nature reserves can enforce environmental protection laws and help to promote the local economy. This will solve the problems of reserves being run to make money. When national reserves are funded, local governments will be able to adopt the same model and provide the funds for nature reserves from their own budgets. The first project should be established in nature reserves hit by the quake; these can then become models for other areas.
小题1:To restore the quakehit ecosystem, government should ________.
| A．forbid locals from taking firewood from the mountainsides |
| B．encourage local people to feed their animals just with straw |
| C．spend large amounts of money relocating the population |
| D．protect the environment without harming locals" interests |
| A．pressures on land were reduced | B．a large amount of coal is provided |
| C．no people live in that area | D．locals take good care of the forest |
| A．local people | B．nature itself |
| C．human involvement | D．government"s effort |
| A．Nature reserves could be helpful to recover the damaged ecosystems. |
| B．Centrallyfunded nature reserves are beneficial to local economy. |
| C．Some nature reserves are created for the purpose of making money. |
| D．The first projects on nature reserves should be set up in quakehit areas. |
