    Agitated Sunspot Cause Trouble
    If the lights in your house keep flickering, blame frequent sunspots.
    A sunspot is actually charged particles flying at the speed of 3 million kilometers an hour out of the surface of the sun to form sun storms.
    __1__.
    The earth, which is directly energized by the sun, is influenced by sun storms in a number of ways.
    __2__. Wireless short-wave communication, which depends on the wave's reflection against this layer of atmosphere, is likely to be jammed. It is said that mobile phone communication may be affected too.
    __3__. According to a research conducted by the Russian scientists from 1957 to 1960, the frequency of earthquakes can be linked to the movement of the sunspots.
    Though little research has been carried out about how exactly the sunspot will negatively harm the health of the people, a paper published by a North Korea observatory says that sun storms may cause an increase in the incidence of heart disease and skin disease. __4__.
    Besides, the nervous system is also affected, and traffic accidents are more frequent when sunspots are active.
    It is hard to say when the sunspots are most violent during their active year, but generally one active period is believed to last possibly eight days. Not long ago there were two violent sun storms breaking out, which seriously affected mobile phone communication, etc. in many parts of the world. __5__.
    A. Ionosphere is high above the earth.
    B. One is that the magnetic filed of the earth is much disturbed because of the sun's interference in the ionosphere which is 80 to 500 kilometers above the earth.
    C. Scientists also say that the active movement of the charged sun storm also has effects on earthquakes
    D. Every 11 years, the sun, as its energy accumulate inside up to a certain point, will send out streams of charged particles, which affect the earth in different ways
    E. But the communication situation in each case returned to normal in about 24 hours.
    F. So, scientists warn that people going outdoors should be careful to protect their exposed skin and eyes with clothes, umbrellas and sunglasses from the strong sunlight rich in ultraviolet rays.

    Dark Forces Dominate Universe
    The Earth,moon,sun and all visible stars in the sky make up less than one percent of the universe.Almost all the rest is dark matter and dark energy, unknown _1_ that puzzle
    astronomers.
    Observations in recent years have changed the basic understanding of how the universe
    evolved and have emphasized for astronomers how little is known _2_ the major forces and
    substances that shaped our world.
    Astronomers now know that luminous matter-stars.planets and hot gas – _3_ only about 0.4 percent of the universe.Non.1uminous components.such as black holes and intergalactic
    gas,make up 3.6 percent.The rest is either dark matter, about 23 percent,or dark energy, about 73 percent.
    Dark matter, sometimes called “cold dark matter,” has been known for some _4_. Only recently have researchers come to understand the pivotal role it _5_ in the formation of stars.planets and even people.
    “We owe our very existence to dark matter,” said physicist Paul Steinhardt and a co-author of a review on dark matter which appeared not long _6_ in the journal Science.
    Steinhardt said it is believed that following the Big Bang,the theoretical _7_ of the universe,dark matter caused particles to clump together.That set up the gravitation processes that led to the formation of stars and galaxies.Those stars,in turn,created the basic chemicals,such as carbon and iron.that were _8_ to the evolution of life.
    “Dark matter dominated the formation of structure in the early universe.”Steinhardt said.“For the first few billion years dark matter contained _9_ of the mass of the universe.You can think of ordinary matter as a froth of an Ocean of dark matter.The dark matter clumps and the ordinary matter falls into it.That led to the _10_ of the stars and galaxies.”
    Without dark matter,“there _11_ be virtually no structures in the universe.”
    The nature of dark matter is _12_.It cannot be seen or detected _13_ .Astronomers know it is there because of its effect on celestial objects than can be seen and measured.
    But the most dominating force Of _14_ in the universe is called dark energy.a recently proven power that astronomers say is causing the galaxies in the universe to separate at a faster and faster speed.
    One scientist said it is clear now _15_ dark matter and dark energy engaged in a gravitational tug of war that,eventually,dark energy won.
