    9．Fear can be a wonderful feeling in our lives，protecting us from dangerous situations and keeping us safe．But fear can also limit our lives significantly．While it may not be conscious，fear may make us think we are unacceptable or that what we have to offer isn't valuable．Fear may make us feel that we are not safe being ourselves．
    To avoid feeling fear，we may limit our lives greatly，living in tiny boxes．Living this way gives us the illusion（假象） of safety but leaves us with an unfulfilling life of no passion．If we shine a light on many of our fears，we see they have a very limited view of what is"safe"and how to"protect"us．Many of our fears are concerned only with protecting us from humiliation（羞辱） and failure．While these fears are doing their jobs incredibly well，they are doing so with faulty and outdated programming．Many fears we have as adults are trying to protect us as they protected us when we were children．Indeed，many of our current，automatic reactions to fear were actually formed when we were children．
    Even so，it's important not to judge ourselves for feeling these types of fears．If we judge ourselves，we will bury our fears or disguise them．By denying our fears，however，we also deny our energy，creativity and passion．
    So what do we do with fear？We recognize the fear for what it is---a feeling we've experienced many times in the past and a feeling we will experience many times in the future．We become very familiar with our own particular brand of fears and how we allow them to control our lives．It is especially beneficial for each of us to become aware of the particular behavior patterns we've adopted when we feel fear，so we can look at our reactions with a sense of humor and compassion．Then，if we wish，we can choose a different response，which can be a scary yet very exciting experience．
    5．According to the first paragraph，fear sometimesD．
    A．protect us when we've made mistakes
    B．makes sure our feelings are not hurt
    C．brings great change to our everyday life
    D．makes us lose confidence in ourselves
    6．According to the author，the ways we react to fearB．
    A．vary from person to person
    B．have been formed since childhood
    C．develop during our growth
    D．will not change until we get old
    7．The last paragraph mainly tells usC
    A．what is the essence of fears
    B．usual reactions we have when feeling fear
    C．how to deal with fears reasonably
    D．the importance of humor and compassion
    8．What would be the best title for the passage？A
    A．Is fear managing your life？
    B．Be calm when feeling fear
    C．What do you fear most？
    D．Passion，chance and fear．

    13．A．recently        B．affects        C．pattern        D．varies      E．movesF．warm          G．regularly       H．special       I．effect       J．evidence
    Big climate changes in the last million years might have come from something very small：dust from outer space．Earth changes between ice ages and warm periods in a （n）（36）C that includes several cycles，including a（37）H one that lasts 100，000years．Scientists（38）A suggested this cycle might be due to changes in the inflow of cosmic dust．
    The idea is that Earth（39）E above and below the imaginary orbit that runs through the sun and Jupiter，completing a cycle every 100，000years．So maybe it（40）G meets amounts of dust during each cycle that produce the climate trend．
    Now there is some（41）J，from ancient cosmic dust near the Azores islands west of Portugal．The large quantity of the dust rises and falls with a wonderful 100，000year cycle during the period 253，000years to 458，000years ago．Periods of more dust are related to（42）F climates．
    But that is a long way from showing that the dust（43）B climate．Some scientists argue that it is not clear how cosmic dust would make the climate warmer while dust from volcanoes is known to make it cooler．They say the cosmic dust is so thin that it is hard to see how it could have any climate（44）I．
