2、movable【答案】A【解析】【选项释义】A. everlasting 永久的，永恒的，经久不变的 B. expansive 广阔的，辽阔的C. outward 表面的，外表的 D. movable 可移动的，活动的【答案】A【考查点】形容词辨析。【解题思路】perpetual的意思为“持续的，长久的”，用来形容snow，指的是安第斯山脉的永久性积雪，everlasting与之词义相近，因此A选项正确。【干扰项排除】B、C、D选项词义与之不符。【句意】智利的许多河流相对较短，大多发源于安第斯山脉，向西流向太平洋。在北部和中部地区，河流的主要水源是安第斯山脉的永久性积雪。2. 填空题Taste

4、y a role in sth.为固定搭配，其意思为“在中起作用”，how big a role到句尾的部分还原成一般陈述语序为taste preference actually plays a big role in brand loyalty，所以D部分应为in。【句意】因为口味是主观问题，所以一般不会对食物进行偏好测试。但由于两大可乐公司可口可乐和百事可乐的营销非常激进，我们想知道口味偏好在品牌忠诚度中到底起到了多大作用。3. 填空题The origin of contemporary sociological references to social structure can be

A B C D【答案】
7、B something去掉【解析】【考查点】从句。【解题思路】that all leaders have something in common是修饰personal qualities的定语从句，其中that充当从句宾语，意思指的是personal qualities，所以B部分的something去掉句子才正确。【句意】似乎并没有所有领导人都具备的一系列个人品质；事实上，如果一个人的素质符合那个特定群体的需要，他就是公认的领导者。5. 单选题Although recent years have seen substantial reductions in noxious pollutant
