                                   How Room Designs Affect Our Work and Feelings
          Architects have long had the feeling that the places we live in can affect our thoughts, feelings and
    behaviors.But now scientists are giving this feeling an empirical (经验的,实证的) basis.They are
    discovering how to design spaces that promote creativity, keep people focused, and lead to relaxation.
         Researches show that aspects of the physical environment can influence creativity.In 2007, Joan
    MeyersLevy at the University of Minnesota, reported that the height of a room's ceiling affects how
    people think.Her research indicates that higher ceilings encourage people to think more freely, which may
    lead them to make more abstract connections.Low ceilings, on the other hand, may inspire a more detailed outlook.
         In addition to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate.Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of
    attention.
         Using nature to improve focus of attention ought to pay off academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia.Tanner and his team found that students in classrooms with unblocked views of at least 50 feet
    outside the window had higher scores on tests of vocabulary, language arts and maths than did students
    whose classrooms primarily overlooked roads and parking lots.
         Recent study on room lighting design suggests that dim (暗淡的) light helps people to loosen up.If that
    is true generally, keeping the light low during dinner or at parties could increase relaxation.Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.
         So far scientists have focused mainly on public buildings."We have a very limited number of studies,
    so we're_almost_looking_ at_the_problem_through_a_straw_(吸管),"architect David Allison says."How do you take answers to very specific questions and make broad, generalized use of them? That's what
    we're all struggling with."

    1. What does Joan MeyersLevy focus on in her research?

    A. Light.  
    B. Ceilings.
    C. Windows.  
    D. Furniture.

    2. The passage tells us that ________.

    A. the shape of furniture may affect people's feelings
    B. lower ceilings may help improve students' creativity
    C. children in a dim classroom may improve their grades
    D. students in rooms with unblocked views may feel relaxed

    3. The underlined sentence in the last paragraph probably means that ________.

    A. the problem is not approached step by step
    B. the researches so far have faults in themselves
    C. the problem is too difficult for researchers to detect
    D. research in this area is not enough to make generalized patterns

    4. Which of the following shows the organization of the passage?

         Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you
    think caused this change in colour? It is soil that has been washed into the river from the riverbank or from the nearby fields.
         Components of Soil
         Soil is made up of a number of layers(层),each having its own distinctive colour and texture.The upper
    layer is known as the litter.It acts like a blanket, limiting temperature changes and reducing water loss.The
    topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus(腐殖质),which is black and gives the topsoil its dark colour.This layer is usually rich in nutrients,oxygen,
    and water.Below the topsoil is the subsoil,a layer that contains more stones mixed with only small amounts of organic matter.This layer is lighter in colour because of the lack of humus.Beneath the soil lies a layer of bedrock.
          Soil forms from the bottom up.Over time bedrock is attacked by rain, wind,frost, and snow.It is gradually broken down into smaller particles in a process called weathering.Plants begin to grow,and rotten materials enrich the topsoil.Most of the soil in Eastern Canada, for example, was formed from weathered rock
    that was exposed when the ice disappeared 12,000 years ago.
         Water Beneath the Soil
         Surface water collects and flows above the ground in lakes, ponds, and rivers.Once in the soil or rock,
    it is called groundwater.Gravity pulls groundwater through the soil in a process called percolation(渗透).
    Eventually the water reaches a layer called the water table.Under this is bedrock through which water
    cannot percolate.
         As water percolates downward,it dissolves organic matter and minerals from the soil and carries them
    to deeper layers.This causes a serious problem because plants require these nutrients for growth.
         Soil pH
          Soil can be acidic,neutral,or basic.The pH of the soil is determined by the nature of the rock from which it was formed, and by the nature of the plants that grow and rot in it.
          The acidity of rain and snow can lower the pH of the groundwater that enters the soil.By burning fossil fuels such as coal,oil and gasoline,humans have been contributing to higher levels of acidity in many soils.When fossil fuels are burned, gases are released into the air and then fall back to earth as acid rain.Acid soil increases the problem of carrying nutrients to lower soil levels.As nutrients are removed,soil is less fertile.Plants grow more slowly in acidic soil,and also become easily attacked by diseases.

    1. The layer of soil that provides necessary nutrients for plant growth is called ________.

    A. litter  
    B. topsoil
    C. humus  
    D. subsoil

    2. According to the text, which of the following is NOT true?

    A. Soil forms from weathered rock on the earth surface.
    B. The deeper layer of soil is darker in colour than the surface soil.
    C. Air pollution is partially responsible for acid soil.
    D. Groundwater tends to carry away nutrients for plant growth.

    3. We can infer from the passage that the water table lies ______.

    A. between the topsoil layer and the subsoil layer
    B. in the subsoil layer above bedrock
    C. between the subsoil layer and bedrock
    D. in the bedrock layer beneath the subsoil

    4. The underlined word "dissolve" is used to express the idea that organic matter and minerals from
         soil are ________.

    A. rushed away into the river
    B. cleaned and purified by water
    C. destroyed and carried away by water
    D. mixed with water and become part of it
