2014考研英語(一)新題型密押模擬題(3)

  Passage 1

  Directions: For question 1—5, choose the most suitable paragraphs from the list A—G and fill them into the numbered boxes to form a coherent text. Paragraphs B and G have been correctly placed.

  [A] There are doubters, of course. The cost of electricity may rise, and some polluters may flee the state, taking jobs away. But California already has one in four of America’s solarenergy jobs and will add many more. Sun, wind, geothermal, nuclear: “We need it all,” says Terry Tamminen, who advised Mr Schwarzenegger. The state is setting up an “interesting experiment”, he thinks. “California goes one way, the United States another.”

  [B] To Europeans, Asians and Australians, this may seem nothing much. After all, the European Union already has a similar emissionstrading market, and a carbon tax is now wending its way through the Australian legislature. India have adopted versions of carbon taxes or emissions trading. But California is in America, which has taken a sharp turn in the opposite direction. Congress debated a capandtrade system in 2009, but then allowed it to die. Republicans attacked it as “capandtax”, and increasingly deny that climate change is a problem at all. Some even point to the bankruptcy of Solyndra, a Californian maker of solar panels which had received lots of federal money, as proof that renewable energy is a wasteful pinko pipedream.

  [C] But California is staying its course. Besides capandtrade, its climatechange law calls for lower exhaustpipe emissions from vehicles and cleaner appliances, and requires the state’s utilities to use renewable energy for onethird of the state’s electricity by 2020. In the Californian mainstream the controversy is not whether to do this, but how.

  [D] More complex and less elegant (but politically easier) than a simple carbon tax, a capandtrade system limits the emissions of dirty industries and puts a price on their remaining pollution so that market forces, in theroy, provide an incentive for reductions. In California’s case, starting in 2013 the government will “cap” the amount of gases (such as carbon dioxide) that industry may emit, and gradually lower that cap. It will also issue permits to companies for their carbon allowance. Firms that reduce their emissions faster than the cap decreases may sell (“trade”) their permits and make money. Firms that pollute beyond their quota must buy credits.

  [E] Jerry Brown started talking about solar power in the 1970s, when he was California’s governor for the first time. He was lampooned for it, but the vision gradually became attractive in a state that is naturally sunny and, especially along the coastline, cares about the environment. So in 2006, under a Republican governor, Arnold Schwarzenegger, California set a goal to reduce its green house gas emissions to 1990 levels by 2020. This year Mr Brown, governor once again, signed the last bits of that goal into law. And this month the state’s airquality regulators unanimously voted to adopt its most controversial but crucial component: a capandtrade system.

  [F] Some firms are building vast fields of mirrors in the Mojave desert to focus the sun onto water boilers and use the steam to spin turbines. But this also requires costly power grids to carry the electricity to the distant cities. Unexpectedly, it has also drawn the ire of some environmentalists, who love renewable energy but hate the mirrors (or wind farms) that ruin landscapes. In the Mojave they fret about a

  environment. I love the diversity of my job. Every day is different. Most tasks require creativity. Now that I am an experienced naturalist, I have the freedom to plan my own day and make decisions about the types of programs that we offer at Peninsula.

  42. _____________

  In my first naturalist job, I spent four out of five days leading school field trips and visiting classrooms. As a state park naturalist I still work with students, but more often lead programs like bird walks, nature crafts, outdoor skills, and trail hikes. I also find myself increasingly involved in management decisions. For example, sometimes the park naturalist is the person who knows where rare orchids grow or where ravens nest. When decisions are made about cutting trees, building trails, or creating more campsites. naturalists are asked to give the “ecological perspective.”

  43. _____________

  Perhaps the grossest thing I’ve done as a naturalist is to boil animal skulls. Visitors like seeing bones and skins—at least after they have been cleaned up! Once, our nature center needed more skulls. A trapper gave me muskrat, raccoon and fox skulls but I had to clean them. First, I boiled the skin and meat off. Boy, did that stink! Then I used dissecting tools and old toothbrushes to clean out the eyeballs. Finally, I soaked the skulls in a bleach solution. I’ve had some embarrassing experiences, too. On my first hike as Peninsula’s new naturalist, I was so excited that I identified a white pine tree as a red pine tree! That’s quite a mistake since the trees are so easy to tell apart. White pine needles are in bundles of five and red pine needles are in bundles of two.

  44. _____________

  Not all state parks are as busy or as big as Peninsula. Not all park naturalists spend the seasons as I do. Nevertheless, park naturalists share certain common interests and responsibilities: A park naturalist might notice that branches of a red maple growing in a field reach out to the side while those of a red maple in a thick forest reach up, and wonder why the trees look different. A naturalist makes things happen. It might be working with workers to clean up part of a river. Park naturalists share knowledge in different ways, but all of them communicate with people. A love of learning--from other people, from plants and animals, from books, and more—is an essential quality. Most naturalists don’t work in places of rare beauty. Many work in city parks or in places that show “wear and tear.” If you can wonder about an inchworm, a juniper bush, or a robin and cause others to wonder, too, then you are ready to become a park naturalist.

  45. _____________

  If you think you want to become a park naturalist, do the following:

  Explore your home landscape. Knowing how people have shaped the land where you live-and how the land has shaped them-will lend a comparison that will serve you well.

  Start a field sketch book.Sketch what you see, where and when. The reason is not to practice art skills (though you may discover you have a talent) but, rather, to practice observation skills.

  Go to college. You will need a 4-year degree. There are several academic routes that lead to the naturalist’s road. I have found ornithology, plant taxonomy and human growth and development to be among my most helpful courses.

  Listen and learn. A college degree is like a ticket. It lets you board the plane but is only the beginning of the journey. Look and listen to those who have already traveled the road for ideas, knowledge and inspiration.

  Passage 2

  Directions: Reading the following and answer questions by finding a subtitle for each of the marked parts or paragraphs. There are two extra items in the subtitle. Mark your answer on ANSWER SHEET . (10 points)

  A. The consequence of losing bones

  B. A better lab than on earth

  C. Two different cases

  D. Multiple effects form weightlessness

  E. How to overcome weightlessness

  F. Factors that are not so sure

  During weightlessness, the forces within the body undergo dramatic change. Because the spine is no longer compressed, people grow taller. The lungs, heart and other organs within the chest have no weight, and as a result, the rib cage and chest relax and expand. Similarly, the weights of the liver, kidneys, stomach and bowels disappear. One astronaut said after his flight: “You feel your guts floating up. I found myself tightening my belly, sort of pushing things back。”

  41.

  Meanwhile muscles and bones come to be used in different ways. Our muscles are designed to support us when stand or sit upright and to move body parts. But in space, muscles used for support on the ground are no longer needed for that purpose; moreover, the muscles used for movement around a capsule differ from those used for walking down a hall. Consequently, some muscles rapidly weaken. This doesn’t present a problem to space travelers as long as they perform only light work. But preventing the loss of muscle tissue required for heavy work during space walks and preserving muscle for safe return to Earth are the subject of many current experiments。

  Studies have shown that astronauts lose bone mass from the lower spine, hips and upper leg at a rate of about 1 percent per month for the entire duration of their time in space. Some sites, such as the heel, lose calcium faster than others. Studies of animals taken into space suggest that bone formation also declines。

  42.

  Needless to say, these data are indeed cause for concern. During space flight, the loss of bone elevates calcium levels in the body, potentially causing kidney stones and calcium crystals to form in other tissues. Back on the ground, the loss of bone calcium stops within one month, but scientists do not yet know whether the bone recovers completely: too few people have flown in space for long periods. Some bone loss may be permanent, in which case ex-astronauts will always be more prone to broken bones。

  43.

  These questions mirror those in our understanding of how the body works here on Earth. For example, elderly women are prone to a loss of bone mass. Scientists understand that many different factors can be involved in this loss, but they do not yet know how the factors act and interact; this makes it difficult to develop an appropriate treatment. So it is with bone loss in space, where the right prescription still awaits discovery。

  44.

  Many other body systems are affected directly and indirectly. One example is the lung. Scientists have studied the lung in space and learned much they could not have learned in laboratories on earth. On the ground the top and bottom parts of the lung have different patterns of air flow and blood flow. But are these patterns the result only of gravity, or also of the nature of the lung itself? Only recently have studies in space provided clear evidence for the latter. Even in the absence of gravity, different parts of the lung have different levels of air flow and blood flow。

  45.

  Not everything that affects the body during space flight is related solely to weightlessness. Also affected, for example, are the immune system and the multiple systems responsible for the amount and quality of sleep(light levels and work schedules disrupt the body’s normal rhythms). Looking out the spacecraft window just before going to sleep(an action difficult to resist, considering the view) can let enough bright light into the eye to trigger just the wrong brain response, leading to poor sleep. As time goes on, the sleep debt accumulates。

  For long space voyages, travelers must also face being confined in a tight volume, unable to escape, isolated from the normal life of Earth, living with a small, fixed group of companions who often come from different cultures. These challenges can lead to anxiety, depression, crew tension and other social issues, which affect astronauts just as much as weightlessness—perhaps even more. Becau
