问题     The changes in globally averaged temperature that have occurred at the Earth’s surface over the past century are similar in size and timing to those【C1】______by models that take into account the combined influences of human factors and solar variability.
    To【C2】______the question of attribution requires the【C3】______of more powerful and complex methods, beyond the use of global averages alone. New studies have focused on【C4】______maps or patterns of temperature change in【C5】______and in models. Pattern analysis is the climatologically equivalent of the more comprehensive tests in the medical analogy mentioned 【C6】______, and makes it possible to achieve more definitive【C7】______of observed climate changes to a particular cause or causes.
    The expected influence of human activities is thought to be much more complex than uniform warming over the entire surface of the Earth and over the whole【C8】______cycle. Patterns of change over space and time therefore provide a more powerful【C9】______technique. The basic idea【C10】______pattern-based approaches is that different【C11】______causes of climate change have different characteristic patterns of climate response or fingerprints. Attribution studies seek,to【C12】______a fingerprint match between the patterns of climate change【C13】______by models and those actually observed.
    The most recent assessment of the science suggests that human activities have led to a discernible 【C14】______on global climate and that these activities will have an increasing influence on future climate. The burning of coal, oil and natural gas, as well as various agricultural and industrial practices, are【C15】______the composition of the atmosphere and contributing to climate change. These human activities have led to increased atmospheric【C16】______of a number of greenhouse gases, including carbon dioxide, methane and so on in the lower atmosphere.
    Human activities, such as the burning of fossil, have also increased the【C17】______of small particles in the atmosphere. These particles can change the【C18】______of energy that is absorbed and reflected by the atmosphere. They are also believed to modify the【C19】______of air and clouds, changing the amount of energy that they absorb and reflect. Intensive studies of the climatic effects of these particles began only recently and the overall【C20】______is uncertain. It is likely that the net effect of these small particles is to cool the climate and to partially offset the warming of increasing concentrations of greenhouse gases. [br] 【C3】
选项 A、application
B、integration
C、avenge
D、intervene
答案 A
解析 To probe the question of attribution requires the 63 of more powerful and complex methods，beyond the use of global averages alone．这个句子中，不定式做主语，介词短语beyond the use of global averages alone在句子中做状语。空格所在句子的大意为：探究问题的原因需要强有力复杂方法的——。对四个选项意思进行分析，可选出适合本句意思的项。A项意思为“应用；申请应用程序；用途”；B项意思为“综合；集成”；C项意思为“替……报仇；报仇；报复”；D项意思为“干涉；调停；插入”。文中所要表达的意思是“对一些方式方法的使用”，所以A项符合题意。
