    The sun is a star. It is a flaming ball of extremely    1    gases. The surface temperature is about 11,000 F., hot enough to turn every    2    to vapor (气体), but relatively cool compared to the strong heat at the    3   .

        Located about 93 million miles    4    the earth, the sun has a diameter (直径) that is nearly equal to 109 of our ear ths    5    up like a row of beach balls, and a mass that is about 330 000 times the mass of the earth.

        The sun is the original source of nearly all our    6   . It is mostly made of hydrogen (氢), 7    it also contains nearly every other kind of atom (原子 )that exists on the earth. The sun obtains its energy from a process of fusion (溶解) in which hydrogen atoms are changed into helium (氦) atoms    8    extreme heat and pressure. This process creates a great noise, but we cannot hear it because    9    does not travel through empty space.

        Our sun is not even    10    large or bright compared to    11    stars. Stars vary in size from smaller than the earth to large enough to hold a good part of our solar system (太阳系)! The    12    of a star shows its temperature. A star may be red, yellow, white, or blue.

        The nearest star is 4.3 light years from the earth. A light year is the    13    light travels in one year, or about    6    million miles. The    14    stars are billions of light years away. Some are    15    far away that if they were to blow up today, their light would continue to be seen from the earth    16    a million years! Our sun is part of a great galaxy (星系) of    30  billion stars called the Milky Way.    17  , there are billions of galaxies within    18    of our telescopes and countless billions beyond.

    阅读理解

    　　In the atmosphere, carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping．

    　　According to a weather expert' s prediction, the atmosphere will be 3℃warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate．If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities．Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(北半球), possibly resulting in an alteration of the earth's chief food growing zones．

    　　In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet．But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels．

    　　Satellite pictures show that large areas of Antarctic ice are already disappearing．The evidence available suggests that a warming has taken place．This fits the theory that carbon dioxide warms the earth．

    　　However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling．Scientists conclude , therefore, that up to now natural influences on the weather have gone beyond those caused by man．The question is：Which natural cause has most effect on the weather?

    　　One possibility is the variable behavior of the sun．Astronomers at one research station have studied the hot spots and "cold" spots(that is, the relatively less hot spots)on the sun．As the sun rotates(使旋转), every 27.5 days, it presents hotter or "colder" faces to the earth, and different aspects to different parts of the earth．This seems to have a considerable effect on the distribution of the earth's atmospheric pressure, and consequently on wind circulation．The sun is also changeable over a long term：its heat output goes up and down in cycles, the latest trend being downward．

    　　Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age．The problem is that the models are predicting that the world should be entering a new Ice Age and it is not．One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(惯性)of the earth's climate．If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun's fading heat．

    (1)

    It can be concluded that a concentration of carbon dioxide in the atmosphere would ________．

    [　　]

    A．

    mean a warming-up in the Antarctic

    B．

    raise the temperature of the earth' s surface

    C．

    prevent the sun's rays from reaching the earth's surface

    D．

    explain the cause of great changes in the climate in the northern hemisphere

    (2)

    The article was written to explain ________．

    [　　]

    A．

    the greenhouse effect

    B．

    the solar effects on the earth

    C．

    the causes affecting weather

    D．

    the models of solar-weather interactions

    (3)

    Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling．This is ________．

    [　　]

    A．

    mainly because the levels of carbon dioxide are rising

    B．

    partly due to changes in the output of solar energy

    C．

    possibly because the ice caps in the poles are melting

    D．

    only due to the effect of the inertia of the earth' s climate

    (4)

    On the basis of their models, scientists believe the opinion that ________．

    [　　]

    A．

    the climate of the world should be becoming cooler

    B．

    the new Ice Age will be delayed by the greenhouse effect

    C．

    the man-made warming effect helps to increase the solar effects

    D．

    it will take thousands of years for the inertia of the earth's climate to take effect

    (5)

    If the assumption about the delay of a new Ice age is correct, ________．

    [　　]

    A．

    ice would soon cover the northern hemisphere

    B．

    the greenhouse effect could work in favor of the earth

    C．

    the best way to overcome the cooling effect would be to burn more fuels

    D．

    the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly

    Adult butterflies use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry predators.
    Sight
    Butterflies have large, compound (multifaceted) eyes, which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a large stand of flowers rather than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but sense polarized（偏振的） light, which indicates the direction the sun is shining, as well as ultraviolet light, which is present on many flowers and guides butterflies to nectar （花蜜）sources.
    Smell
    Butterflies have a very well-developed sense of smell, but it's not in their nose (since they don't have one). Sense receptors located in their antennae, feet, and many other parts of the body help butterflies find food (usually flower nectar), and mates (the female smells the male's pheromones).
    Taste
    Butterfly's feet have sense organs that can taste the sugar in nectar, letting the butterfly know if something is good to eat or not. Some females also taste host plants in order to find appropriate places to lay their eggs. Adult butterflies and moths feed using a proboscis, a long, coiled tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
    Hearing
    Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations.
    Butterflies may possess senses we don't even know about yet because their anatomy is very different than ours, and therefore difficult to understand when perceived through our own human senses.
    【小题1】From the passage we can know that butterflies can see_____

    A．thing behind themB．thing in the distance
    C．most bright colorsD．flower nectar from a distance
    【小题2】 Butterflies can easily find food resources by using their______.
    A．sense organs of sight and smellB．sense organs of sight and taste
    C．sense organs of smell and hearingD．sense organs of smell and taste
    【小题3】 How do butterflies feed themselves?
    A．by using their feetB．by using a tube.
    C．by using sense receptorsD．by using their wings.
    【小题4】What is the passage mainly about?
    A．The food sources of butterflies.B．The habits of butterflies.
    C．The unusual body of butterflies.D．the sense of butterflies.

    Have you ever been to the beautiful country of Holland and its capital Amsterdam? Anyone who has traveled to Amsterdam would probably agree on one thing: Amsterdam’s story is a tale of two cities — one during the day and a completely different one at night.
    When the sun is up, this largest city in the Netherlands sits quietly on the Amstel River. You can rent a bicycle, visit the Van Gogh or Anne Frank museum, or take a water taxi. But when the sun goes down, the partying begins. In the big clubs and in the coffee shops, tourists gather to talk politics and smoke.
    Several areas of the city clearly show the two worlds that rule Amsterdam. And they’re all within a short cab ride of each other. For example, Dam Square attracts daytime sightseers to its festivals, open markets, concerts and other events. Several beautiful and very popular hotels can be found there. And there’s the Royal Palace and the Magna Plaza shopping mall. But at night party-seekers come to the square. Hip hop or funk music (疯狂音乐) is heard there. So if you come, be ready to dance. The clubs don’t shut down until 4 am.
    And while you’re there, check out the various inexpensive ways to tour the city. Don’t worry about getting lost. Although Dutch is the official language, most people in Amsterdam speak English and are happy to help you with directions. And you’ll notice that half the people walking around in the streets are on bicycles they rent. Amsterdam also has a well-planned canal system. For about 10 dollars, you can use the canal bus or a water taxi to cruise (巡游) the “Venice of the North”.
    The city has a historic past. One impressive (印象深刻的) place to visit is the Anne Frank House on Nine Street. It was there that the young Jewish girl wrote her famous diary during World War II. Visitors can view Anne’s original diary and climb behind the bookcase to the room where she and her family hid from the Nazis for two years.
    【小题1】 What means of transport is not available to visitors in Amsterdam?

    A．A carriage.B．A bicycle.
    C．A canal bus.D．A water taxi.
    【小题2】What can you learn about by visiting the Anne Frank House?
    A．The wonderful past of Amsterdam.
    B．The experience of a beautiful girl survivor.
    C．The life of Jewish during World WarⅡ.
    D．The suffering of the Dutch in wars.
    【小题3】The passage is intended to _______.
    A．call up people’s memories of World WarⅡ
    B．tell readers what A Tale of Two Cities is about
    C．instruct visitors what to do and see in Holland
    D．offer readers some information about Amsterdam
    【小题4】This passage is most likely taken from _______.
    A．a private diaryB．a test paperC．a travel journeyD．a history book
