6、答案及解析解析

1.从下文可以看出，由于地球上的水源不充足，有时有泉水的地方就意味着控制own拥有

2.根据下文中的“thedesert”可判断出是干旱地区distant”遥远的〃；deserted“废弃的；wild“野生的”3比较上文中的“desert”可确定选rich即使没有大片的富饶的土地也要控制richland“富饶的土地”.这是一个双重否定句，表示在美国西部早期，人们为了水源发生枪战的事并不罕见uncommon罕见的”.makelaws“制定法律”是一个固定搭配6制定法律保护移民者用水的权力和按照规定使用水源winner“胜利者”；fighter“战士”；supporter支持者；settler“移民者”asisknowntousall为尚定句型，意为“众所周知”根据常识可推断出世界上没有足够的水供人们随便使用plentiful表示“绰绰有余的，enough“足够的”theamountofwater“水量”type类型，；quality“质量”；level水平”.决定任何特殊时期的用水量需要仔细计划require“需要；request〃请求〃;mean〃意味着；suggest“建议”.上文uthereisnotenoughwaterinallplacesforeveryonetouseasmuchashelikes”说明由于水源不足，需要仔细地计划特殊时期的用水量，以便使人们更加有效地用水effectively”有效地”.农民必须根据供水预报改变他们的用水量accordingto“根据”.thecorrectwatersupplyforecast正确的供水预报.根据下文中的“dependontheadvanceknowledgeofsnowonmountainsnotofwaterunderground^可确定应选above作为正确答案theabove指“山上的积雪”；thebelow指地下水”.人们对人工增加降雨量的兴趣不断增加raise是及物动词，后面要接宾语rise是不及物动词.根据常识可知，在冬天雪会堆积在山顶上onmountaintops“在山顶上”.科学家正在研究利用积雪的方法makeuseof“利用.人们为了利用山上的积雪，需要不断地收集有关数据thegathereddata”收集的数据”.操作员只要按一下按钮随时都可以获得数据pressabutton“按按钮”.根据时间状语“inthenearfuture”可确定要用一般将来时

6.haveexplored.which

8.because

9.especiallylO.known解析La此处填不定冠词a表示“一”perfonnances考查名词单复数前面有anumberof表示“许多”，后接可数名词复数like考查介词的用法前文讲的是他们也将参观许多历史名胜，如木兰山和将军庙所以此处用likeits考查代词的用法此处要用形容词性物主代词作定语修饰directorocreating考查现在分词作状语haveexplored考查动词的时态由本句中的时间状语inthelastfewyears可知此处用动词的现在完成时态which考查定语从句的关系词由于此处是非限制性定语从句，且先行词指物所以填which？because考查状语从句此处表原因句意:Bancroft补充说“我认为花木兰的传说之所以能吸引西方人主要是因为花木兰对家人尤其是对她父亲的尊重”especially考查词性转换由语境可知，此处要用副词especiallyknown考查非谓语动词此处用过去分词known作定语修饰前面的LiuYifeio
